DETAILED DESCRIPTION OF THE INVENTION

[0027] Considering the numbering adopted in the figures, the filter for a brake device F comprises a case 1, 1′ made of sheet metal, a cylindrical tubular filtering element 2 and a dismantlable axial fastening system which allows the filter assembly of the present disclosure to first be assembled in the brake device F and dismantled; second it provides axial fastening of the filter when same is assembled on the filter device; and third it provides axial fastening of the filtering element 2.

[0028] The filtering element 2 is located and fitted inside the case 1, 1′, wherein the case 1, 1′ includes at least one cylindrical tubular lateral wall 3 having two opposite end edges, a first and a second. The filtering element 2 sits on an internal surface of the lateral wall 3 of the case 1, 1′. Said lateral wall 3 of the case 1, 1′ includes a set of holes 4.

[0029] Once the filter of the present disclosure is assembled around the brake device F, the latter is encapsulated within an inner space of the filter, wherein said inner space is radially delimited by the filtering element 2 having a cylindrical tubular configuration. The filtering element 2 is configured for retaining contaminating particles that are released from the brake device F housed inside the inner space delimited by the filtering element 2, such as for example the brake device described in present disclosure patent ES2705358, wherein said brake device externally includes protrusions fitting into axial channels 5 located in the filtering element 2.

[0030] In a first embodiment of the present disclosure shown in FIGS. 1 to 3, the cylindrical tubular case 1 is a whole body and includes an annular bottom 6 in the form of a washer which is integrally attached to the first end edge of the lateral wall 3 forming part of the case 1 itself, whereas a support ring 7 is coupled in a dismantlable manner to the second end edge of the case 1.

[0031] To that end, the support ring 7 includes an annular groove 8 in which the second end edge of the case 1 fits. Furthermore, to secure the fastening of the support ring 7 on the case 1, engagement mechanisms 9 are included, each of which comprises a pivoting blade 9a, an articulated frame 9b connected in an articulated manner to the pivoting blade 9a, and a fixed flange 9c on which the articulated frame 9b engages in an anchoring position of the engagement mechanism 9.

[0032] Each pivoting blade 9a is coupled in an articulated manner to a protruding appendage integral with the support ring 7, whereas the fixed flange is integral with the case 1.

[0033] In this first embodiment of the present disclosure being described, the dismantlable axial fastening system of the filter assembly is formed by the annular bottom 6 of the case 1 and by the support ring 7, wherein both the annular bottom 6 and the support ring 7 include through holes 10, 11 aligned with the axial channels 5 of the filtering element 2.

[0034] In a second embodiment of the present disclosure shown in FIG. 4, the case 1′ comprises two parts which are attached by means of a hinged articulation 12, while at the same time including engagement mechanisms 9′ such as those described above for being able to engage between one another the two parts of said case 1′ and being able to stably put together the structure of the cylindrical tubular case 1′. Said engagement mechanisms 9′ are located in proximity to facing edges of the two parts of the case 1′.

[0035] In this second embodiment of the present disclosure, the filtering element 2 comprises two separate parts that are joined together when the filter is assembled around the brake device F, wherein in said assembled position the filtering element 2 forms a cylindrical tubular shape equivalent to that described in the first embodiment.

[0036] In the second embodiment of the present disclosure, there are furthermore included two opposing support rings 7′ constituting the dismantlable axial fastening system of the filter when same is assembled in the brake device F. To that end, the support rings 7′ are placed in parallel planes inside the case 1′ in contact with the internal surface of the case 1′, wherein said contact is close to the two opposite end edges: first and second of the case 1′. The support rings 7′ include through holes 13, 14 aligned with the axial channels 5 of the filtering element 2.

[0037] Moreover, both the support ring 7 of the first embodiment and one of the support rings 7′ of the second embodiment of the present disclosure include pairs of boreholes 15 which are configured for sleeves 16 to be fitted therein for connecting to cooling conduits of the brake device described in patent ES2705358, which belongs to the same proprietor as the present disclosure.

[0038] Therefore, the assembly of the case 1, 1′ made of drilled sheet metal together with the filtering element (2) surrounds the brake device F, such that all the particles that are released in each braking are deposited in said filtering element 2, preventing them from being released into the air.

[0039] When the filter has been used for a certain number of kilometres, a first option includes the filtering element 2 being replaced with another new one and being able to recycle the used filtering element 2; and a second option includes being able to use the filtering element again if it is washable. In this situation, the brake device of the mentioned patent is once again in conditions where it can continue braking and protecting the environment.

[0040] The protection of the present disclosure also extends to “soundproofing” with respect to the noise generated by the brake device in each braking, and to the “protection of the brake device against external agents”, such as dust, sand, small stones, etc.

[0041] In the design of the encapsulation of the brake device of the referenced patent, the easy replacement of the filter has been taken into account, where once the wheel of a vehicle has been removed, it leaves the encapsulation of the case 1, 1′ in view, in such a way that by actuating the engagement mechanisms 9, 9′ by hand, the case 1, 1′ is released and can be manually removed outwards, leaving the particle filtering element 2 in view, which in turn, by extracting it also outwards, allows its easy replacement, proceeding by the same method for its assembly.

[0042] The figures show descriptive but non-limiting examples of the encapsulation system mainly applicable to the brake device of the referenced patent ES2705358, and its design variants for the easy replacement of the particle filtering element 2, also depending on the positioning arrangement of said brake device; it should also be noted that the filtering of harmful particles is 100%.

[0043] It is important to understand that the brake device of the referenced patent has the technical capability to be installed both on the wheel (non-suspended) and on the vehicle chassis (suspended). The first embodiment of the present disclosure would be appropriate for being installed on the wheel of a vehicle, whereas the second embodiment of the present disclosure could be installed both ways.

[0044] It is important to understand that the brake device of the referenced patent ES2705358 has the technical capability to be installed both on the wheel (non-suspended) and on the vehicle chassis (suspended), such that the first embodiment of the filter of the present disclosure would be appropriate for being installed on the wheel of a vehicle, whereas the second embodiment of the present disclosure would be appropriate for being installed both ways.
