Description

Technical Field

[0001] The invention relates to an air brake having a brake caliper and a spring support for fixing a brake lining, which is used, for example, in a truck or trailer vehicle. Background Art

[0002] This type of spring support 10 is Figure 1 The spring support 10 has an end 12 with which it is pushed into a recess of the brake caliper during assembly, and an opposite end 14 with a hole 16 with which the spring support is screwed to the brake caliper.

[0003] The spring support 10 is assembled into the brake caliper 20. Figure 2 . The spring support 10 is first pushed with the end 12 into the recess 22 of the brake caliper 20 and then pressed onto the brake caliper 20 until it rests on the brake caliper 20. In the process, the two leaf springs 24, 25 are pressed downward, so that the leaf springs exert pressure on the two brake linings 26, 27 for fixing the brake linings 26, 27. The spring support 10 is then screwed to the brake caliper 20 with the screw 28, as shown in FIG. Figure 3 As shown in .

[0004] The recess 22 is deeper than necessary in order to compensate for tolerances. As a result, during assembly, the spring support 10 can be pushed too deeply into the recess 22. As a result, the end 14 of the spring support 10 collides with the boundary 29 of the brake caliper 20 and cannot be screwed to the brake caliper 20. Figure 4 In this case, an additional assembly step is required to calibrate the spring support 10, which leads to increased manufacturing costs.

[0005] There is therefore a need for an air brake with a brake caliper and a spring support which has low assembly costs. Summary of the invention

[0006] It is therefore an object of the present invention to provide an air brake having a brake caliper and a spring support which has a simplified assembly and thus has low costs.

[0007] This object is achieved by an air brake according to claim 1 and a commercial vehicle according to claim 10 .

[0008] Based on the following description of these measures, the dependent claims contain advantageous developments and improvements of the invention.

[0009] The invention relates to an air brake having a brake caliper, at least one leaf spring and a spring support. When assembling the spring support, before the spring support is screwed to the brake caliper, the spring support is pushed into a recess of the brake caliper, and the spring support has a marking portion for aligning the spring support, or the brake caliper has a notch for aligning the spring support.

[0010] In an advantageous embodiment, a marking on the spring support or a recess in the brake caliper indicates how far the spring support is to be pushed into the recess of the brake caliper when the spring support is assembled.

[0011] In a preferred embodiment, the marking portion has the form of a notch or a recess.

[0012] In a further preferred embodiment, the identification portion is in the form of a sticker or a colored identification portion.

[0013] In a further preferred embodiment, the identification feature is in the form of a hole.

[0014] In a further preferred embodiment, the identification feature has the form of a recess.

[0015] In a further advantageous embodiment, the identification is at a distance from the end of the spring support by which the spring support is to be pushed into the recess of the brake caliper during assembly, which distance is equal to the length by which the spring support is to be pushed into the recess of the brake caliper.

[0016] In a further advantageous embodiment, the spring support has a hole for screw connection at one end and a marking at the opposite end.

[0017] In a further advantageous embodiment, the recess of the brake caliper has a depth which is equal to the depth into which the spring support is to be pushed into the recess of the brake caliper during assembly.

[0018] Air brakes can advantageously be used in commercial vehicles, in particular in trucks, and in trailer vehicles. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] This specification illustrates the principle according to the disclosure of the present invention. It should therefore be understood that those skilled in the art will be able to design various arrangements, which, although not explicitly described herein, still embody the principle according to the disclosure of the present invention and should also be protected within their scope.

[0033] In a preferred embodiment, the air brake according to the present invention comprises a brake caliper and a spring support 30a, the spring support having a marking portion 38a at one end 32 for correct assembly, such as Figure 5 , the spring support is pushed into the recess of the brake caliper with this end. In this embodiment, the marking 38a is in the form of a notch or a recess. The marking 38a indicates how deep the spring support 30a should be pushed into the recess of the brake caliper during assembly. At the end 34 opposite to this end, the spring support 30a has a hole 36, with which the spring support is screwed to the brake caliper during assembly of the air brake.

[0034] In another preferred embodiment, the spring support 30b has a marking portion 38b, which is in the form of a sticker or a colored marking portion, such as Figure 6 as shown in .

[0035] In another preferred embodiment, the spring support 30c has an identification portion 38c in the form of a hole, such as Figure 7 as shown in .

[0036] In another preferred embodiment, the spring support 30d has an identification portion 38d in the form of a notch at the end 32, which is opposite to the end 34 having the threaded portion, such as Figure 8 as shown in .

[0037] The markings 38a-d in particular specify the distance from the end 32 of the spring support 30a-d, at which the spring support 30a-d will be pushed into the recess 42 during assembly, and the distance is equal to the length of the spring support 30a-d to be pushed into the recess 42. The spring support 30a-d is, for example, assembled in a position corresponding to the end 32 of the spring support 30a-d. Figure 2 The brake caliper 20 corresponds to the brake caliper 40 .

[0038] In another preferred embodiment, the brake caliper 41 of the air brake 100 has an identification portion above the recess 42, into which the spring support 30e is pushed when the air brake 100 is assembled, and the identification portion has the form of a notch 50, such as Fig. 9 . The spring support 30e has no identification portion here. The depth of the notch 50 is equal to the depth of the spring support 30e pushed into the recess 42 when the spring support 30e is correctly assembled. Therefore, when the spring support 30e is correctly assembled, the edge 52 of the spring support 30e that enables the spring support 30e to be pushed into the recess 42 is just above the edge 54 of the notch 50.

[0039] The markings 38a-d of the spring supports 30a-d are selected in particular in such a way that the markings 38a-d are located at the upper edge 56 of the recess 42 of the brake caliper 41 when correctly assembled. Fig.11 shown. Fig.11 The spring support shown in the figure corresponds to the spring support 30a having the recess 38a. This ensures that the other end 34 of the spring support 30a does not collide with the boundary 58 of the brake caliper 41. Fig.12 . Therefore, when assembling the air brake 100, no additional assembly step is required to align the spring support 30a, because the spring support 30a can be positioned correctly immediately in the first assembly step. The two leaf springs 44, 45 are pressed onto the brake linings 46, 47 of the air brake 100 by the spring support 30a, thereby positioning them.

[0040] All examples and conditional statements mentioned herein should be understood without limitation to these specifically cited embodiments. The present disclosure is not limited to the embodiments described herein. There is still room for various matching schemes and modifications considered by those skilled in the art based on their expertise and belonging to the present disclosure.
