DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

(7) FIG. 1 schematically shows a part of a rail vehicle 2 in a side view.

(8) FIG. 1 shows a bogie 4 of the rail vehicle 2 and a part of a body 6 of the rail vehicle 2. The body 6 of the rail vehicle 2 is mounted on the bogie 4 via a rotary pan of the bogie 4 (not shown in the figure), such that the body 6 can be rotated relative to the bogie 4.

(9) The bogie 4 comprises a bogie frame 8 and two wheelsets 10 among other things (see FIG. 2). FIG. 1 shows two wheels 12 of the two wheelsets 10. Furthermore, the bogie 4 is embedded into a bogie cavity 14 of the rail vehicle 2.

(10) Furthermore, the rail vehicle 2 has a multi-part bogie cladding 16, via which the bogie 4 is clad. The bogie cladding 16 closes off the bogie cavity 14.

(11) The bogie cladding 16 comprises two bulkheads 18 attached to the body 6 and two base walls 20 attached to the body 6. In addition, the bogie cladding 16 comprises two wheelset claddings 22 and a center cladding 24 arranged between the two wheelset claddings 22, where the two wheelset claddings 22 and the center cladding 24 are attached to the bogie 4, in particular to the bogie frame 8. In addition, the bogie cladding 16 comprises two side claddings 26 (not shown in FIG. 1) attached to the body 6 (see FIG. 2). The aforementioned parts 18-26 of the bogie cladding 16 can each consist of one element or a plurality of interconnected elements, in particular a plurality of interconnected plates.

(12) The bogie cavity 14 is delimited upward by a base section 28 of the body 6. In the vehicle longitudinal direction 30, the bogie cavity 14 is delimited by the two bulkheads 18.

(13) The bogie cladding 16 has an opening 32 between its front base wall 20 and its front wheelset cladding 22, in relation to the vehicle longitudinal direction 30. Similarly, the bogie cladding 16 has an opening 32 between its rear base wall 20 and its rear wheelset cladding 22, in relation to the vehicle longitudinal direction 30. These two openings 32 are both a movement gap that allows a relative movement between the respective base wall 20 and the respective wheelset cladding 22.

(14) FIG. 2 shows schematically the bogie 4 and the bogie cladding 16 of the rail vehicle 2 from FIG. 1 in a view from above.

(15) FIG. 2 shows both wheelsets 10 of the bogie 4 with their wheelset bearings 34 and wheels 12. In addition, the two previously mentioned side claddings 26 of the bogie cladding 16 are shown in FIG. 2.

(16) The bogie cladding 16 further has an opening 32 in each case between the parts 22, 24 of the bogie cladding 16 attached to the bogie 4 and the side cladding 26 arranged on the left-hand side of the vehicle and between the parts 22, 24 of the bogie cladding 16 attached to the bogie 4 and the side cladding 26 arranged on the right-hand side of the vehicle. These openings 32 too are in each case a movement gap that allows a relative movement between the respective side cladding 26 and the parts 22, 24 of the bogie cladding 16 attached to the bogie 4.

(17) At the aforementioned openings 32, the bogie cladding 16 is in each case fitted with at least one elastically deformable flow-inhibitor, which serves to reduce an inflow of outside air through the respective opening 32 into the bogie cavity 14 (cf. FIG. 3-FIG. 6). The flow-inhibitors are not shown in FIG. 1 and FIG. 2 for purposes of clarity.

(18) FIGS. 3-6 each schematically show a first cladding element 36a of the bogie cladding 16 and a second cladding element 36b of the bogie cladding 16 arranged adjacent to the first cladding element 36a.

(19) Between the two cladding elements 36a, 36b the bogie cladding 16 has an opening 32, in particular in the form of a gap.

(20) The two cladding elements 36a, 36b can be attached to the bogie 4. Alternatively, the two cladding elements 36a, 36b can be attached to the body 6. Further alternatively, the first cladding element 36a can be attached to the bogie 4, while the second cladding element 36b is attached to the body 6, or vice versa. For example, the first cladding element 36a can be one of the two base walls 20 of the bogie cladding 16 or an element of the respective base wall 20. The second cladding element 36 can be, for example, one of the two wheelset claddings 22 of the bogie cladding 16 or an element of the respective wheelset cladding 22.

(21) In the embodiment of FIG. 3, the bogie cladding 16 has a flow-inhibitor 38 arranged at the opening 32, which is attached to the first cladding element 36a. This flow-inhibitor 38 is formed as a brush, where the flow-inhibitor 38 has a brush trim consisting of a plurality of brush fibers 40.

(22) The flow-inhibitor 38 extends in the embodiment of FIG. 3 only over part of the width 42 of the opening 32. This means that the flow-inhibitor 38 is spaced apart from the second cladding element 36b. With the aid of the flow-inhibitor 38, it becomes possible to ensure that a smaller part of an outside air flow 44 flows through the opening 32 into the bogie cavity 14 (compared to the case in which no such flow-inhibitor 38 is arranged at the opening 32).

(23) In the embodiment of FIG. 4, the bogie cladding 16 comprises a first flow-inhibitor 38a arranged at the opening 32, which is attached to the first cladding element 36a, and a second flow-inhibitor 38b arranged at the opening 32, which is attached to the second cladding element 36b. The respective flow-inhibitors 38a, 38b are formed as a brush and have a brush trim consisting of a plurality of brush fibers 40.

(24) In the embodiment of FIG. 4, the two flow-inhibitors 38a, 38b only extend over part of the width 42 of the opening 32. This means that the first flow-inhibitor 38a is spaced apart from the second cladding element 36b and the second flow-inhibitor 38b is spaced apart from the first cladding element 36a. In the embodiment of FIG. 4, the two flow-inhibitors 38a, 38b touch and engage in one another.

(25) In the embodiment of FIG. 5, the bogie cladding 16 comprises a first flow-inhibitor 38a arranged at the opening 32, which is attached to the first cladding element 36a, and a second flow-inhibitor 38b arranged at the opening 32, which is attached to the second cladding element 36b. These two flow-inhibitors 38a, 38b are each formed as a brush and each have a brush trim consisting of a plurality of brush fibers 40.

(26) In addition, the two flow-inhibitors 38a, 38b in the embodiment of FIG. 5 extend over the entire width 42 of the opening 32. This means that the first flow-inhibitor 38a is in contact with the second cladding element 36b and the second flow-inhibitor 38b is in contact with the first cladding element 36a. In the embodiment of FIG. 5, the two flow-inhibitors 38a, 38b are spaced apart from one another.

(27) In the embodiment of FIG. 6, the bogie cladding 16 has a flow-inhibitor 38 arranged at the opening 32, which is attached to the first cladding element 36a. This flow-inhibitor 38 is formed as a sealing lip and is in contact with the second cladding element 36b.

(28) In each of the embodiment of FIG. 3 to FIG. 6, the respective flow-inhibitors 38, 38a, 38b inhibit an inflow of air through the opening 32 into the bogie cavity 14.

(29) At least one of the two bulkheads 18 of the bogie cladding 16 (cf. FIG. 1 or FIG. 2) can have an opening through which, for example, a cable and/or a fluid line are/is guided. At such an opening, the bogie cladding 16 may likewise have a flow-inhibitor of the above-described type to reduce an inflow of air into the bogie cavity 14 through this opening.

(30) FIG. 7 shows schematically a bogie 4 and a bogie cladding 16 of a further rail vehicle 46 in a view from above.

(31) The description of the following exemplary embodiment is primarily limited to the differences from the exemplary embodiments of FIG. 1 and FIG. 2, to which reference is made with regard to the same features and functions.

(32) In the bogie cladding 16 from FIG. 7, both side claddings 26 each have two openings 32. One of the wheelset bearings 34 is in each case guided through these openings 32. In other words, one of the wheelset bearings 34 of the bogie 16 protrudes out of the openings 32 in each case.

(33) At these openings 32, the bogie cladding 16 is in each case also fitted with an elastically deformable flow-inhibitor that serves to reduce an inflow of outside air through the respective opening 32 into the bogie cavity 14 (cf. FIG. 8).

(34) FIG. 8 shows an exemplary section of one of the side claddings 26 of the bogie cladding 16 from FIG. 7. One of the openings 32 of the side cladding 26, from which one of the wheelset bearings 34 protrudes, is located in the section of the side claddings 26 that is depicted.

(35) The bogie cladding 16 has a flow-inhibitor 38 arranged at the opening 32, which is formed as a brush and comprises a plurality of brush fibers 40. This flow-inhibitor 38 surrounds the wheelset bearing 34 protruding from the opening 32 in the circumferential direction 48 thereof.

(36) In the present example, the brush fibers 40 of the flow-inhibitor 38 are spaced apart from the wheelset bearing 34. Alternatively the brush fibers 40 can touch the wheelset bearing 34.

(37) Although the invention has been illustrated and described in detail by the preferred exemplary embodiments, the invention is not restricted by the disclosed examples and other variations can be derived therefrom without departing from the scope of protection of the invention.

(38) Thus, while there have been shown, described and pointed out fundamental novel features of the invention as applied to a preferred embodiment thereof, it will be understood that various omissions and substitutions and changes in the form and details of the devices illustrated, and in their operation, may be made by those skilled in the art without departing from the spirit of the invention. For example, it is expressly intended that all combinations of those elements which perform substantially the same function in substantially the same way to achieve the same results are within the scope of the invention. Moreover, it should be recognized that structures and/or elements shown and/or described in connection with any disclosed form or embodiment of the invention may be incorporated in any other disclosed or described or suggested form or embodiment as a general matter of design choice. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto.
