DETAILED DESCRIPTION

[0029] Selected embodiments of the present disclosure will now be described with reference to the accompanying drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments of the invention are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.

[0030] Referring initially to FIG. 1, a bicycle 1 is illustrated with a hydraulic brake system 2, including a hydraulic brake actuation device 4 operatively connected to a hydraulic brake caliper assembly 8 configured to engage a brake disk 6 to slow rotation of a wheel 3 to which the brake disk 6 is mounted in response to actuation of the hydraulic brake actuation device 4. To operatively connect the hydraulic brake actuation device 4 to the hydraulic brake caliper assembly 8, a hydraulic hose coupling assembly 10 is provided that includes a banjo fitting 12 and a hydraulic hose 20 securable therein as described below. The hydraulic hose 20 extends between the hydraulic brake actuation device 4 and the hydraulic brake caliper assembly 8, and contains hydraulic fluid therein. Hydraulic fluid pressure is transmitted from the hydraulic brake actuation device 4 to the hydraulic brake caliper assembly 8 via the hydraulic fluid in the hydraulic hose 20. In this manner, when a rider actuates the hydraulic brake actuation device 4, the hydraulic brake caliper assembly 8 is caused to grip the brake disk 6 to slow rotation of the wheel 3.

[0031] The banjo fitting 12 of the hose coupling assembly 10 is typically provided on the hydraulic brake caliper assembly 8, but may alternatively or in addition be provided on the hydraulic brake actuation device 4. The hydraulic hose coupling assembly 10 and banjo fitting 12 of the present disclosure are useful in particular during installation of the hydraulic hose 20, since they can be used to install a sealed hose with hydraulic fluid therein in a manner that inhibits air from becoming entrained therein.

[0032] Although only the front portion of the bicycle 1 is depicted in FIG. 1, it should be understood from the drawings and the description herein that the bicycle 1 includes both a front and a rear wheel, and that a respective hydraulic brake system 2 including one or more respective hydraulic hose coupling assemblies 10 and banjo fittings 12 may be installed in each of the front and rear wheels. Since features of both front and rear brake systems are the same, description of rear portions of the bicycle and rear portions of the hydraulic brake system are omitted for the sake of brevity.

[0033] In FIGS. 2A-2C and 3, a first embodiment of a hydraulic hose coupling assembly 10 is illustrated. The hydraulic hose coupling assembly 10 includes a banjo fitting 12, the hydraulic hose 20, a banjo bolt 22, a threaded fitting 24, a deformable tubular bushing 26.

[0034] The banjo bolt 22 is an elongated member that is configured to be coupled to the hydraulic brake caliper assembly 8, and attach the hydraulic hose coupling assembly 10 to the hydraulic brake caliper assembly 8, while also fluidly coupling the hydraulic hose coupling assembly to the hydraulic brake caliper assembly 8. The banjo bolt 22 includes a body having a shaft portion 22a and a cap portion 22b. The shaft portion 22a is typically threaded, as shown in FIG. 3, and configured to threadingly engage a threaded hole 8a in the hydraulic brake caliper assembly 8. The shaft portion 22a includes at least one hydraulic passageway 27 extending therethrough. The hydraulic passageway 27 includes one or more longitudinal subpassageways 27a extending along a longitudinal axis of the banjo bolt 22, and an annular passageway 27b fluidly connecting each of the longitudinal subpassageways 27a. In the embodiment illustrated in FIG. 3, three longitudinal subpassageways 27a are shown in the form of external flutes formed at respective positions equilaterally about axis 32b. It will be appreciated that other forms are possible, such as an internal bore that replaces the annular passageway 27b or the externally fluted longitudinal subpassageways 27a. Further, a different number (e.g., 1, 2, or 4 or more) of longitudinal subpassageways 27a may be provided.

[0035] As shown in FIGS. 2A, 2B, and 3, the banjo fitting 12 of the hydraulic hose coupling assembly 10 includes an annular portion 14, a hose attachment portion 16, and a seal rupturing structure 18 within the hose attachment portion 16.

[0036] The annular portion 14 of the banjo fitting 12 may have a cylindrical, polygonal, or curvilinear shape with an internal bore 30 that extends along a first axis 32a of the banjo fitting 12. The internal bore 30 of the annular portion 14 is may be longer in the first axis 32a than it is in diameter along a second axis 32b. The relatively longer length in the first axis 32a helps provide sufficient room for both the annular passageway 27b of the banjo bolt 22 and the surrounding regions of the shaft 22a of the banjo bolt 22 with a larger outer diameter that contact the inner wall of the internal bore 30, while the reduced diameter along the second axis 32b helps the overall size of the top and bottom surface of the hose coupling assembly 10 remain compact. The banjo bolt 22 is configured to be installed within the internal bore 30 of the annular portion 14, where an inner surface of the annular portion 14 extends rotatably around the banjo bolt 22 enabling the rest of the hose coupling assembly 10 to be pivoted relative to the banjo bolt 22 when the banjo bolt 22 is secured. Furthermore, when the banjo bolt 22 is installed in the annular portion 14 of the banjo fitting 12, the hydraulic passageway 27 of the banjo bolt is open on one end of the banjo bolt 22 (i.e., at distal ends of the longitudinal subpassageways 27a) to the hydraulic brake caliper assembly 8, and open at the other end (i.e., adjacent a portion of annular passageway 27b) to an opening 14a in an inner surface of the annular portion 14 of the banjo fitting 12, which is fluidly coupled to the internal fluid passageway 36 of the hose attachment portion 16. When assembled, the banjo bolt 22 is also configured to direct the flow of hydraulic fluid between the hydraulic hose coupling assembly 10 and the hydraulic brake caliper assembly 8. The internal bore 30 of the annular portion 14 may include recesses or concave annular shaped grooves that retain a pair of sealing rings 34. Further, annular axial end faces of the annular portion 14 of the banjo fitting 12 may be coated with a friction resistant material so as to improve retention.

[0037] The hose attachment portion 16 extends radially from the annular portion 14 of the banjo fitting 12 and is integrally formed as a one piece element with the annular portion 14 in the illustrated embodiments, although a two-piece construction may be possible. The hose attachment portion 16 extends along the second axis 32b of the banjo fitting 12, formed at an angle to the first axis 32a of the banjo fitting 12.

[0038] An internal fluid passageway 36 extends along the second axis 32b of the banjo fitting 12 and passes through the entire length of the hose attachment portion 16, with the seal rupturing structure 18 positioned within the internal fluid passageway 36. It will be appreciated that the length of the internal fluid passageway 36 may be substantially longer than the hydraulic passageway 27 that extends along a longitudinal axis of the banjo bolt 22, which achieves the potential advantage of improving the strength of the hydraulic hose attachment. Referring to FIG. 2C, the internal fluid passageway 36 has a first diameter portion 37, a second diameter portion 39 having an interior diameter 39a smaller than the first diameter portion 37, and a step portion 38 provided between the first diameter portion 37 and second diameter portion 39. The seal rupturing structure 18 includes an insertion portion 46 formed to be inserted in the second diameter portion 39 of the internal fluid passageway 36.

[0039] The seal rupturing structure 18 may have a cylindrical shape to allow fluid flow through the seal rupturing structure 18, so that the portions of the internal fluid passageway 36 on each side of the seal rupturing structure 18 are in fluid communication. The seal rupturing structure 18 includes a needle portion 40 on the side of the internal fluid passageway 36 containing the first diameter portion 37. The needle portion 40 has a proximal end 40a, and a beveled distal end 40b opposite to the proximal end 40a. The seal rupturing structure 18 also includes a flange portion 42 provided on the proximal end 40a of the needle portion 40. The insertion portion 46 extends from the proximal end of the needle portion 40.

[0040] The hydraulic hose 20 illustrated in FIGS. 2A and 2B, for example, may be a flexible tube that is used for conveying hydraulic fluid from a hydraulic brake actuation device to the hydraulic hose coupling assembly 10 under pressure, and may be manufactured of a polymer material. The hydraulic hose 20 has a first end portion 20a with a first opening 20b and a seal 52 that seals the first opening 20b before the hydraulic hose coupling assembly 10 is assembled. The seal 52 is formed of a thin flexible sheet of metal foil, or a suitable similar material. The seal 52 is adhesively attached to an axial end surface of the first end portion 20a of the hydraulic hose 20 to overlie the first opening 20b of the hydraulic hose 20. Thus, the seal 52 forms a seal that seals the first opening 20b of the hydraulic hose 20. The sealed hydraulic hose typically contains hydraulic fluid therein, prior to the assembly process.

[0041] When the hydraulic hose coupling assembly 10 is assembled, the hydraulic hose 20 is coupled to the hose attachment portion 16 of the banjo fitting 12. The seal 52 prevents fluid communication between the banjo fitting 12 and the interior 54 of the hydraulic hose 20 until the seal 52 is ruptured by the seal rupturing structure 18. As further seen in FIGS. 2B and 2C, the hydraulic hose 20 is configured such that the seal 52 of the hydraulic hose 20 is ruptured or punctured by the seal rupturing structure 18. In particular, the seal 52 is physically ruptured by the seal rupturing structure 18 in response to the first end portion 20a of the hydraulic hose 20 being fully inserted, i.e. coupled, to the hose attachment portion 16 of the banjo fitting 12. The seal 52 is configured to be easily ruptured by the seal rupturing structure 18. Coupling the first end portion 20a of the hydraulic hose 20 to the hose attachment portion 16 of the banjo fitting 12 causes fluid communication between an interior 54 of the hydraulic hose 20 and the internal fluid passageway 36.

[0042] Referring to FIGS. 2B and 2C, the needle portion 40 of the seal rupturing structure 18 is formed for rupturing or puncturing the seal 52. In particular, the beveled distal end 40b of the needle portion 40 punctures the seal 52 and is inserted into a first opening 20b of the hydraulic hose 20 in response to the first end portion 20a of the hydraulic hose 20 being fully inserted into the hose attachment portion 16 of the banjo fitting 12. When the first end portion 20a of the hydraulic hose 20 is coupled to the hose attachment portion 16, the flange portion 42 of the seal rupturing structure 18 is pushed against an annular end face of the hydraulic hose 20, with the seal 52 disposed in between, which securely retains the seal rupturing structure 18 relative to the first opening 20b of the hydraulic hose 20. The outer surface of the insertion portion 46 of the seal rupturing structure 18 is fitted to the inner surface of the second diameter portion 39 of the hose attachment portion 16. The insertion portion 46 of the seal rupturing structure 18 is configured to be retained in the second diameter portion 39.

[0043] The seal rupturing structure 18 may comprise a resin material such as a plastic, although any suitable rigid material may be utilized for the seal rupturing structure 18 as needed and/or desired. In the preferred embodiment, the seal rupturing structure 18 is formed separately from the hose attachment portion 16 of a different material than the hose attachment portion 16, and coupled to the hose attachment portion 16. However, it should be appreciated that in alternative embodiments, the seal rupturing structure 18 could be formed integrally with the hose attachment portion 16, or formed separately from the hose attachment portion 16 of the same material as the hose attachment portion 16.

[0044] When the hydraulic hose coupling assembly 10 is assembled and the seal rupturing structure 18 is ruptured, the hydraulic passageway 27 of the banjo bolt 22, the internal fluid passageway 36 of the hose attachment portion 16 of the banjo fitting 12, and the interior 54 of the hydraulic hose 20 are fluidly coupled to form a first fluid path when the hydraulic hose is coupled to the hose attachment portion 16 of the banjo fitting 12. By preventing coupling of the interior 54 of the hydraulic hose 20 to the internal fluid passageway 36 of the hose attachment portion 16, this configuration achieves the potential advantages of reducing the risk of air from being trapped in the hydraulic brake system, as well as minimizing the leakage of hydraulic fluid, during assembly of the hydraulic hose 20 to the hydraulic hose coupling assembly 10, therefore improving performance of the hydraulic brake system.

[0045] As seen in FIGS. 2A and 2B, a threaded fitting 24 has a longitudinal bore with the first end portion 20a of the hydraulic hose 20 and the deformable tubular bushing 26 disposed therein while the hydraulic hose coupling assembly 10 is assembled. The threaded fitting 24 has a threaded portion 66 configured to threadingly engage an external threaded portion 16a of the hose attachment portion 16 of the banjo fitting 12. The threaded fitting 24 is configured to secure the hydraulic hose 20 within the hose attachment portion 16 upon rotational engagement of the threads of the threaded portion 66 with the threads of the external threaded portion 16a of the hose attachment portion 16.

[0046] The deformable tubular bushing 26 has an inner surface 26a and a pair of annular inclined surfaces 26b. While the hydraulic hose coupling assembly 10 is assembled, the deformable tubular bushing 26 is disposed around the first end portion 20a of the hydraulic hose 20, and one of the pair of inclined surfaces 26b is positioned within an bushing receiving portion 37b of the internal fluid passageway 36 of the hose attachment portion 16. Where the internal fluid passageway 36 has a bushing receiving portion 37b and a hose receiving portion (a first diameter portion) 37, and an interior diameter 37c of the bushing receiving portion 37b is larger than an interior diameter 37a of the hose receiving portion 37. The deformable tubular bushing 26 is positioned between the bushing receiving portion of the internal fluid passageway and the threaded fitting 24 such that one of the pair of annular inclined surfaces 26b comes into contact with a surface of the bushing receiving portion 37b of the internal fluid passageway 36 and the other one of the pair of annular inclined surfaces 26b comes into contact with the threaded fitting 24 upon threaded engagement of threaded portion 66 of the threaded fitting 24 with the external threaded portion 16a of the hose attachment portion 16.

[0047] The deformable tubular bushing 26 is configured to be deformed during threaded engagement of the threaded fitting 24 with the banjo fitting 12. In particular, the deformable tubular bushing 26 decreases in axial length along the second axis 32b and decreases in radial width as the deformable tubular bushing deforms in response to engagement of the threaded fitting 24 with the external threaded portion 16a of the hose attachment portion 16. As a result, the deformable tubular bushing 26 is deformed so as to squeeze the first end portion 20a of the hydraulic hose 20, and secure the hydraulic hose 20 within the internal fluid passageway 36 of the hose attachment portion 16 of the banjo fitting 12. The deformable tubular bushing 26 may comprise a rigid material such as metal. For example, the deformable tubular bushing 26 may comprise a copper or a copper alloy, although any suitable rigid material may be utilized for the deformable tubular bushing 26 as needed and/or desired.

[0048] Referring to FIG. 4, a hydraulic hose coupling assembly 110 is provided according to a second embodiment of the present disclosure. Since the hydraulic hose coupling assembly 110 is generally similar to that of the first embodiment with the exception of the threadings of the hose attachment portion 116 and the threaded fitting 124, detailed description thereof is abbreviated here for the sake of brevity. It is to be noted that like parts are designated by like reference numerals throughout the detailed description and the accompanying drawings.

[0049] As shown in FIG. 4A, the hose attachment portion 116 of the banjo fitting 112 can also be provided with an internal threaded portion or bore 116b. In this embodiment, the threaded fitting 124 is configured to threadingly engage the internal threaded portion 116b of the hose attachment portion 116. Accordingly, the threaded portion 166 of the threaded fitting 124 is disposed on an external surface of the threaded fitting 124, instead of on an internal surface, as seen with the first embodiment.

[0050] The widest point of the internal fluid passageway 136 of the hose attachment portion 116 is elongated along the second axis 132b to accommodate the internal threaded portion 116b, but the hose receiving portion 137 (a first diameter portion) of the internal fluid passageway 136 is shortened in the second axis 132b.

[0051] Similar to the previous embodiment, the deformable tubular bushing 126 is positioned so that one of the pair of annular inclined surfaces 126b comes in to contact with a surface of the bushing receiving portion 137b of the internal fluid passageway 136 and the other one of the pair of annular inclined surfaces 126b comes into contact with the threaded fitting 124 upon threaded engagement of the threaded fitting 124 with the internal threaded portion 116b of the hose attachment portion 116. The deformable tubular bushing 126 disposed therebetween. The threaded fitting 124 of this embodiment is also configured to secure the hydraulic hose 120 within the hose attachment portion 116 by deforming the deformable tubular bushing 126 so as to squeeze the first end portion 120a of the hydraulic hose 120, and secure the hydraulic hose 120 within the internal fluid passageway 136 of the hose attachment portion 116 upon rotational engagement of the threads of the threaded portion 166 with the threads of the internal threaded portion 116b of the hose attachment portion 116. For all other aspects of this embodiment of the hydraulic hose coupling assembly, the configuration reflects the primary embodiment of the present disclosure.

[0052] As seen in FIGS. 5A and 5B, a hydraulic hose coupling assembly 210 is provided according to a third embodiment of the present disclosure. Since the hydraulic hose coupling assembly 210 is generally similar to that of the first embodiment with the exception of the presence of a tubular insert 228, detailed description thereof is abbreviated here for the sake of brevity. In this embodiment, the hydraulic hose 220 includes a tubular insert 228 provided on a first end portion 220a and within a first opening 220b of the hydraulic hose 220. The tubular insert 228 has a tubular portion 270 and an annular flange portion 268 provided on an end of the tubular portion 270. A longitudinal passageway 272 passes through within the tubular portion 270 and the annular flange portion 268. The seal 252 is attached to an annular flange portion 268 of the tubular insert 228. The outer surface of the tubular portion 270 may have a plurality of inclined barbs such that the tubular portion 270 is securely retained in the interior 254 of the hydraulic hose 220. The tubular insert 228 is configured to be retained in the first end portion 220a of the hydraulic hose 220 and to provide radial support at the first end portion 220a of the hydraulic hose 220 while the deformable tubular bushing 226 squeezes the first end portion 220a of the hydraulic hose 220 in response to threaded engagement of the threaded fitting 224 with the hose attachment portion 216 of the banjo fitting 212. Accordingly, the tubular insert 228 comprises a rigid material, such as a metallic material. For example, the tubular insert 228 may comprise a copper or a copper alloy, although any suitable rigid material may be utilized for the tubular insert 228 as needed and/or desired.

[0053] When the tubular insert 228, installed to the first end portion 220a of the hydraulic hose 220, is coupled to the hose attachment portion 216 of the banjo fitting 212, the flange portion 242 of the seal rupturing structure 218 is pushed against the annular flange portion 268 of the tubular insert 228, with the seal 252 disposed therebetween, which securely retains the seal rupturing structure 218 relative to the longitudinal passageway 272 of the tubular insert 228. The needle portion 240 of the seal rupturing structure 218 is configured to rupture the seal 252, and to be retained in the longitudinal passageway 272 of the tubular insert 228. When the hydraulic hose coupling assembly 210 is assembled and the seal rupturing structure 218 is ruptured, the hydraulic passageway 227 of the banjo bolt 222, the internal fluid passageway 236 of the hose attachment portion 216, the longitudinal passageway 272, and the interior 254 of the hydraulic hose 220 are fluidly coupled to form a first fluid path.

[0054] Although FIGS. 5A and 5B depicts the tubular insert 228 in a hydraulic hose coupling assembly 210 in which the a hose attachment portion 216 of a banjo fitting 212 has an external threaded portion 216a, it should be obvious to one skilled in the art that the tubular insert 228 could be implemented in numerous embodiments, including one in which the hose attachment portion 216 of the banjo fitting 212 has an internal threaded portion 216b. For all other aspects of this embodiment of the hydraulic hose coupling assembly, the configuration reflects the primary embodiment of the present disclosure.

[0055] While specific embodiments of the hydraulic hose coupling assembly have been described in detail, the particular arrangements disclosed are meant to be illustrative only and not limiting. The features of the various embodiments described above, as well as modifications thereof, may be variously combined without departing from the scope of this disclosure.
