Description

[0001] The present invention relates to a guide element for a vehicle disc brake for arrangement between a brake pad assembly and a brake carrier of the vehicle disc brake. The present invention further relates to a brake carrier for such a vehicle disc brake. In addition, the present invention relates to a vehicle disc brake with such a brake carrier and at least one guide element.

[0002] Guide elements of the aforementioned type are known from the prior art, for example from patent applications WO 2016 / 141135 A1 and WO 2014 / 205177 A1. Furthermore, patent applications JP 2013-96454 A, WO 2012 / 147875 A1 and WO 01 / 31223 A1 disclose disc brakes and brake clips.

[0003] It is an object of the present invention to provide a guide element which, when mounted on a brake carrier of a vehicle disc brake, can be quickly and easily attached in a correct position on the brake carrier.

[0004] This problem is solved according to the invention by a guide element having the features of claim 1.

[0005] Further advantageous embodiments are the subject of the dependent claims.

[0006] The guide element for a vehicle disc brake is designed for placement between a brake pad assembly and a brake carrier of the vehicle disc brake and has a guide section and a receiving section. The guide section is designed to guide a guide extension of the brake pad assembly.

[0007] The receiving section defines a receiving area for receiving a projection of the brake pad carrier. The receiving section has at least one centering element that projects into the receiving area.

[0008] The recording area is formed by a roof surface, an intermediate surface, and a mounting surface. The roof surface, the intermediate surface, and the mounting surface define the recording area between them.

[0009] The at least one centering element serves to ensure the correct positioning of the guide element on the brake carrier during assembly. In other words, the at least one centering element prevents assembly errors. By correctly positioning the guide element on the brake carrier using the at least one centering element, the functionality of the guide element can be ensured, particularly with regard to the smooth movement of the brake pad assembly during braking or the return of the brake pad assemblies to their initial position after braking.

[0010] The centering element, at least one of which protrudes into the receiving area, tapers towards a smaller size. This allows the guide element to self-align during installation and automatically be forced into the correct position on the brake carrier's projection. The centering element, at least one of which is trapezoidal in shape, tapers towards its end.

[0011] At least one centering element extends at least essentially perpendicular to the intermediate surface and the roof surface.

[0012] The at least one guide element can have a predetermined elasticity. The elasticity of the guide element can result from its construction or shape. The guide element can have a substantially S-shaped base body. Due to the elasticity of the guide element, the at least one centering element can be reliably held in engagement with the projection of the brake carrier.

[0013] The guide elements can guide the brake pad assemblies within the guides of the brake carrier. In particular, the guide elements can serve to receive and guide the guide projections of a brake pad assembly. A brake pad assembly typically comprises a brake pad backing plate and a friction lining attached to the brake pad backing plate. The two guide projections can be located on opposite sides of the brake pad backing plate of the brake pad assembly. The guide elements can prevent undesirable noises, such as rattling noises during driving, which result from relative movements between the brake pad assemblies and the brake carrier.

[0014] The receiving section can be essentially C-shaped. The roof surface and the intermediate surface can be at least substantially parallel to each other. The roof surface and the intermediate surface can be connected to each other via the contact surface. The contact surface can extend at least substantially perpendicular to the intermediate surface and / or the roof surface. The roof surface can form a top surface of the guide element. This applies in particular to a state when mounted on the vehicle. When mounted on a brake carrier, the contact surface can rest against an end face of a projection on the brake carrier.

[0015] The at least one centering element can run at least substantially parallel to the at least one contact surface. The contact surface can be designed to rest against an end face of the brake carrier's projection.

[0016] The at least one centering element can taper towards its end. Preferably, the at least one centering element is essentially trapezoidal. Alternatively, the at least one centering element can be essentially triangular. The tapered end of the centering element can be located closest to the intermediate surface, i.e., have the smallest distance to the intermediate surface.

[0017] The at least one centering element can be connected to the roof surface and / or to a surface of the receiving section adjoining the roof surface. The at least one centering element can be held against the roof surface by the surface adjoining the roof surface. The surface adjoining the roof surface can be angled relative to the roof surface. For example, the surface adjoining the roof surface can be at an angle of 90° to the roof surface. The at least one centering element can be located at the end of the roof surface opposite the mounting surface. In other words, the roof surface can extend substantially perpendicularly between the mounting surface and the centering element.

[0018] The at least one centering element can be designed such that it projects a predetermined distance into the receiving area. The distance by which the at least one centering element projects into the receiving area can depend on the design of the brake carrier's projection. The at least one centering element can extend into the receiving area from the roof surface or from the surface adjoining the roof surface in the direction of the intermediate surface. The roof surface and the intermediate surface can be at least substantially parallel to each other. The at least one centering element can extend into the receiving area over a predetermined portion of the distance between the roof surface and the intermediate surface. This predetermined portion of the distance between the roof surface and the intermediate surface can be between 15% and 50% of the total distance between the roof surface and the intermediate surface.Preferably, this predetermined portion can be between 20% and 40% of the distance. Particularly preferably, this predetermined portion can correspond to 25% of the distance between the roof surface and the intermediate surface.

[0019] The at least one centering element can be arranged offset from the plane of a back surface of the guide section. In particular, the at least one centering element can be arranged in front of the back surface of the guide section with respect to a mounting direction of the guide element. This allows the at least one centering element to ensure correct positioning of the guide element on the brake carrier before the back surface of the guide section contacts the brake carrier. Preferably, the at least one centering element can be arranged offset from at least one retaining claw formed on the guide section. The at least one centering element can be arranged in front of the retaining claw in the mounting direction of the guide element. This ensures that the centering of the guide element on the projection of the brake carrier is completed before the at least one retaining claw comes into contact with the brake carrier.

[0020] The guide elements may include a return mechanism. This return mechanism ensures that the brake pad assemblies release the brake disc after braking, i.e., detach from it. The return mechanism may include a spring with a spring arm. A lug may be provided on the spring arm. The lug of the spring arm can engage behind the guide projections of the brake pad assembly. When the brakes are applied, the brake pad assemblies are moved towards the brake disc against the preload force of the return mechanism's spring. After braking, the spring arm, with its lug, returns the brake pad assembly to its initial position in the brake carrier guide.The reset device prevents the brake pad assembly from remaining in permanent contact with the brake disc, which could potentially lead to residual grinding torques and thus increased energy consumption.

[0021] The present invention further relates to a vehicle disc brake, in particular a floating caliper brake, with a brake carrier. The brake carrier has at least one projection designed for attaching a guide element, wherein the projection has at least one centering recess for centering the guide element. The centering recess is preferably designed to engage the at least one centering element.

[0022] The centering recess can be groove-shaped. The centering recess can be larger or at least wider than the end of the centering element projecting into the receiving area. In particular, the centering recess can be wider than the free end of the centering element in a direction transverse to the mounting direction of the guide element. The brake carrier projection can be received by the centering recess within the receiving area of ​​the guide element defined by the receiving section. The centering recess can be formed on a centering surface that, when the brake carrier is mounted on the vehicle, forms the upper surface of the projection.

[0023] The at least one centering recess can have two side walls extending at least substantially parallel to each other, which define the width of the centering recess. The side walls of the centering recess can be connected to each other by two walls, which can define the length of the centering recess. One of these walls can form the beginning of the centering recess and the other wall its end. The centering recess can also have an opening. The opening can be formed on the end face of the brake carrier's projection. Starting from this opening, the centering recess extends substantially perpendicular to this end face.The centering element of the guide element, when the guide element is placed onto the brake carrier's projection, can engage with the centering recess, which has an opening, to force the guide element into its correct position on the brake carrier. The width of the centering recess can be adapted to the shape and / or size of the centering element. The width of the centering recess can be greater than the free end of the centering element projecting into the receiving area. Once the centering element's side edges rest against the walls of the centering recess, the guide element can be forced into the correct position on the brake carrier's projection due to its elasticity.

[0024] The centering recess of the brake carrier can interact with the centering element to center or position the guide element on the brake carrier. During the installation of the guide element on the brake carrier, the at least one centering element can engage in the centering recess of the brake carrier. The elasticity of the guide element presses the at least one centering element into the centering recess. The at least one centering element guides the guide element into the correct position on the brake carrier. The centering or positioning of the guide element on the brake pad carrier can be completed before the at least one retaining claw can engage the brake carrier.

[0025] The present invention further relates to a vehicle disc brake with such a brake carrier and at least one guide element of the type described above. The vehicle disc brake can, for example, be a floating caliper disc brake. In such a vehicle disc brake, the brake carrier can be rigidly attached to the vehicle brake. The brake caliper can be slidably attached to the brake carrier by means of brake caliper guide devices. The brake caliper can be actuated by means of a hydraulic actuating device. For this purpose, the hydraulic actuating device can have a piston that is slidably received in a recess in the brake caliper. The brake caliper can encompass a brake disc coupled to the vehicle wheel. The brake carrier can guide the brake pad assemblies.The brake caliper can exert clamping forces to displace the brake pad arrangements onto the brake pad arrangements in order to carry out a braking process by clamping the rotating brake disc.

[0026] In such a vehicle disc brake, at least one centering element can extend at least substantially perpendicular to the intermediate surface and / or the roof surface.

[0027] In this type of vehicle disc brake, at least one centering element can become smaller towards its free end projecting into the receiving area. In this way, the guide element can align itself automatically during installation and is automatically forced into the correct position on the projection of the brake carrier.

[0028] In such a vehicle disc brake, at least one centering element can, for example, taper towards its end in a trapezoidal shape.

[0029] Exemplary embodiments of a guide element and a brake carrier according to the invention are described in more detail below with reference to the accompanying schematic figures. These show: Fig. 1. A perspective view of a disc brake with a brake caliper and a brake carrier; Fig. 2 a view of the disc brake from Fig. 1 from the bottom; Fig. 3 a side view of a brake carrier with a brake pad assembly attached to it; Fig. 4 a sectional view of the disc brake from the Fig. 1, Fig. 2 to Fig. 3, in which the brake pad arrangements and the guide elements for guiding the brake pad arrangements are shown; Fig. 5 a perspective view of a brake carrier according to a first embodiment; Fig. 6 a perspective view of a brake pad arrangement; Fig. 7 a perspective partial view of the brake carrier according to the first embodiment with a guide element attached to it; Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12 to Fig. 13 different views of a guide element; and Fig. 14 a perspective partial view of a brake carrier according to a second embodiment with a guide element attached to it.

[0030] Fig. Figure 1 shows a perspective view of a disc brake 1000. The disc brake 1000 can be designed as a floating caliper disc brake. The disc brake has a brake caliper 100 and a brake carrier 200. The brake carrier 200 has an outer carrier section 202 and an inner carrier section 204, between which a Fig. One brake disc (not shown) can be inserted. The brake carrier 200 can be rigidly mounted to a vehicle or to an axle of the vehicle (not shown). The brake caliper 100 is slidably connected to the brake carrier 200 via brake caliper guide devices 102 and 104.

[0031] Fig. Figure 2 shows a view of the 1000 disc brake from below. Fig. Figure 2 shows the brake caliper 100, the brake carrier 200, and brake pad assemblies 300 and 302. The brake pad assemblies 300 and 302 are arranged on the brake carrier 200. A [missing information] can be located between the brake pad assemblies 300 and 302. Fig. The brake caliper 100 can apply clamping forces to the brake pad assemblies 300 and 302 to move them towards the brake disc. To execute a braking action, the brake pad assemblies 300 and 302 are pressed against the brake disc.

[0032] Fig. Figure 3 shows a side view depicting the brake pad assembly 300 and the brake carrier 200. Mounting projections 206 are formed on the inner carrier section 204. Each mounting projection 206 is provided with a mounting opening 208 through which the brake carrier 200 can be attached to a vehicle. The brake carrier 200 has two guides 210 and 212, which serve to guide the brake pad assembly 300.

[0033] The brake pad assembly 300 comprises a brake pad carrier plate 304 and a Fig. 3. Friction lining (not shown). Guide projections 306 and 308 are formed on the brake pad carrier plate 304. The guide projections 306 and 308 are formed on opposite sides of the brake pad carrier plate 304 and thus extend laterally away from the brake pad carrier plate 304. The guide projections 306 and 308 are partially received in the guides 210 and 212 of the brake pad carrier 200. Guide elements 400 are arranged on the guides 210 and 212 of the brake pad carrier 200; these serve in particular for vibration damping in order to prevent undesirable noise such as squeaking. The guide elements 400 are able to suppress acoustically perceptible, vibration-related noises that can occur during vehicle operation due to relative movements between the brake pad arrangement 300 and the brake carrier 200 in the area of ​​the guides 210 and 212.

[0034] Fig. Figure 4 shows a sectional view of the 1000 disc brake. Fig. Figure 4 shows the brake caliper 100, the brake carrier 200 with its outer carrier section 202 and its inner carrier section 204, the brake pad arrangements 300, 302 and the guide elements 400.

[0035] The brake caliper 100 is equipped with a hydraulic actuating device 106. The hydraulic actuating device 106 has a recess 108 formed in the brake caliper and a piston 110, which is slidably mounted in the recess 108. The piston 110 can be pressurized with hydraulic pressure to move the brake pad assemblies 300, 302 in the direction of a Fig. Move the 4 brake discs not shown.

[0036] Like brake pad assembly 300, brake pad assembly 302 also has a brake pad carrier plate 310. A friction lining 312, 314 is attached to each of the brake pad carrier plates 304, 310 of brake pad assemblies 300, 302. During braking, the friction linings 312, 314 provide friction with the Fig. 4 brake discs not shown create a frictional connection.

[0037] Two guide elements 400 are arranged on each of the outer support section 202 and the inner support section 204 of the brake carrier 200. The guide elements 400 serve to guide the brake pad assemblies 300, 302 on the brake carrier 200 and engage with the brake pad carrier plates 304, 310 for this purpose. The guide elements 400 are arranged between the brake carrier 200 and the brake pad assemblies 300, 302.

[0038] Fig. Figure 5 shows a perspective view of the brake carrier 200 with the guide elements 400 attached to it. Of the four guides typically found on a brake carrier 200, in Fig. Figure 5 shows only guides 210, 212 and 214. A guide element 400 is arranged on each of guides 210, 212, 214.

[0039] Fig. Figure 6 shows a perspective view of the brake pad assembly 300. The brake pad assembly 300 comprises the brake pad carrier plate 304 and a friction lining 312, which is attached to the brake pad carrier plate 304. Guide projections 306 and 308 are formed on opposite sides of the brake pad carrier plate 302.

[0040] Fig. Figure 7 shows a perspective partial view of the brake carrier 200. Fig. Figure 7 shows the guides 212 and 214 for the brake pad assemblies 300 and 302, with a guide element 400 attached to guide 214. Guides 212 and 214 are essentially identical in construction. In the following explanation of the construction of guides 212 and 214, only guide 212 will be referred to, as it is shown in Figure 7. Fig. Figure 7 is shown without guide element 400.

[0041] The guide 212 is formed by a roof surface 216, a back surface 218, and a base surface 220. The base surface 220 and the roof surface 216 extend essentially parallel to each other and are connected by the back surface 218. The end surface 222 adjoins the roof surface 216. The end surface 222, in turn, adjoins the centering surface 224. The roof surface 216 and the centering surface 224 run essentially parallel to each other and are connected by the end surface 222, which extends at right angles to both the roof surface 216 and the centering surface 224. The surfaces 216, 222, and 224 form a projection V, which is received in the receiving section 414 of the guide element 400. The receiving section 414 of the guide element 400 is explained in more detail below.

[0042] A groove-shaped centering recess 226 is formed in the centering surface 224. The centering recess 226 extends along the centering surface 224 in the direction of arrow BR. Arrow BR also indicates the direction along which the guide elements 400 can be attached to or detached from the brake carrier 200. The centering recess 226 extends substantially perpendicular to the end face 222. The centering recess 226 has two parallel side walls 226a and 226b, which extend at an angle of substantially 90° to the end face 222. The side walls 226a and 226b are connected to each other via walls 226c and 226d. The wall 226c is closest to the end face 222 and extends parallel to the end face 222. A web remains between the wall 226c and the end face 222, separating the wall 226c from the end face 222.The side walls 226a and 226b and the walls 226c and 226d define the centering recess 226. The two side walls 226a and 226b define the width of the centering recess 226 between them. The walls 226c and 226d define the length of the centering recess 226 in the direction of arrow BR. In the direction of arrow BR, surface 226c forms the beginning of the centering recess 226 and wall 226d its end. The centering surface 224 forms the upper surface of the projection V formed by surfaces 216, 222, and 224. The centering surface 224 is located on the side of the projection V facing away from the guide 212. The floor area 220 is adjoined by an area 218, which runs perpendicular to the floor area 220.

[0043] The guide element 400 is attached to the guide 214. The guide element 400 has a substantially C-shaped guide section 402 in which the guide extensions 306 and 308 of the brake pad carrier plate 304 (see Fig. 3) can be recorded section by section. The C-shaped guide section 402 is formed by a base surface 404, a back surface 406, and an intermediate surface 408. The back surface 406 connects the base surface 404 with the intermediate surface 408. The back surface 406 extends substantially perpendicular to the base surface 404 and the intermediate surface 408. The base surface 404 and the intermediate surface 408 extend substantially parallel to each other. Starting from the intermediate surface 408, a support surface 410 extends at an angle of at least substantially 90° to the intermediate surface 408. The roof surface 412 also extends from the support surface 410 at an angle of at least substantially 90°.

[0044] The intermediate surface 408, the mounting surface 410, and the roof surface 412 form a recording section 414, which defines a recording area AB. The intermediate surface 408, the mounting surface 410, and the roof surface 412 define the recording area AB between themselves. A centering element 416, or centering tab, is arranged on the recording section 414. The centering element 416 projects into the recording area AB. The centering element 416 extends at an angle of approximately 90° to the roof surface 412. The centering element 416 is connected to the surface 418, which extends at an angle of essentially 90° to the roof surface 412. The surface 418 adjoins the roof surface 412. The roof surface 412 forms the top of the receiving section 414. The centering element 416 engages in the centering recess 226 on the centering surface 224 of the brake carrier 200.By engaging the centering element 416 in the centering recess 226, the guide element 400 can easily be attached to the brake carrier 200 in the position intended for it.

[0045] A return mechanism for the brake pad assembly 300 (not shown) is provided on the guide section 402. The return mechanism has a spring arm 420 with a lug 422 at its end and a loop-shaped spring 424. The spring 424 connects the spring arm 420 to the base surface 404 such that the spring arm 420 extends between the base surface 404 and the intermediate surface 408, and thus within the guide section 402. The spring 424 of the return mechanism provides a return force for the brake pad assembly 300. The return mechanism engages the guide extensions 306 and 308 with its spring arm 420 via its lug 422 in order to move the brake pad assembly 300 back to its initial position after a braking operation. This prevents the brake pad assembly 300 from remaining in permanent contact with the brake disc (not shown).The residual grinding torques resulting from the permanent contact of the brake pad assembly 300 with the brake disc can thus be prevented by the return mechanism. Such residual grinding torques counteract the vehicle's propulsion and thereby increase its energy consumption. To transmit the return force, the spring arm 420 engages the guide projections 306 and 308 on the brake pad carrier plate 304 with its nose 422. Fig. The directions of movement in which the spring arm with its nose 422 can be displaced are represented by a double arrow P. The restoring force acts along the arrow P in the direction of the spring 424.

[0046] Extending from the base surface 404 is a further contact surface 426. This contact surface 426 runs at least substantially perpendicular to the base surface 404. During braking, the brake pad carrier plate 304 abuts the contact surface 426 in order to transmit the reaction forces resulting from the frictional engagement between the friction lining 308 and the brake disc to the brake carrier 200. Adjoining the contact surface 426 is a section of the guide element 400 with a surface 428 that extends perpendicular to the contact surface 426. After the brake pad assemblies 300, 302 have been mounted on the brake pad carrier plate 302, the section with surface 428 can engage it and preload it against a surface of the guides 210 and 212 on the brake carrier 200. By means of the section of the guide element 400 covering an area of ​​428, unwanted noise developments, such as rattling, can be prevented during driving.

[0047] The Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12 to Fig. Figure 13 shows various views of a guide element 400. The intermediate surface 408, the mounting surface 410, and the roof surface 412 define the receiving area AB between them. The centering element 416 is arranged on the receiving section 414. The centering element 416 projects into the receiving area AB. The centering element 416 extends at an angle of at least substantially 90° to the roof surface 412 and at least substantially parallel to the mounting surface 410. The centering element 416 is formed on the surface 418, which extends at least perpendicularly to the roof surface 412. The surface 418 adjoins the roof surface 412. As can be seen in particular in the top view of the guide element 400 shown in Figure 13, the following view is shown: Fig. As can be seen from Figure 13, the surface 418 and the centering element 416 are essentially in the same plane in the top view. The contact surface 410 can abut an end face 222 of the projection V of the brake carrier 200 (see Figure 13). Fig. 7).

[0048] The centering element 416 is arranged at the end of the roof surface 412 opposite the mounting surface 414. The roof surface 412 thus runs perpendicularly between the mounting surface 414 and the centering element 416. The centering element 416 extends from the surface 418 adjoining the roof surface 412 towards the intermediate surface 408 into the receiving area AB, specifically over a predetermined portion of the distance A between the roof surface 412 and the intermediate surface 408. The roof surface 412 and the intermediate surface 408 run at least substantially parallel to each other. According to the illustrated embodiment, this predetermined portion of the distance A is approximately 25% of the distance A between the roof surface 412 and the intermediate surface 408.

[0049] The centering element 416 is essentially trapezoidal in shape (see Fig. 10) The centering element 416 thus tapers towards its free end projecting into the receiving area AB. Due to this shape of the centering element 416 and the elasticity of the guide element 400, the guide element 400 can be automatically aligned and forced into the correct position on the brake carrier 200. The elasticity of the guide element 400 can result from its design. The guide element 400 has an S-shaped base body formed by the guide section 402 and the receiving section 414. The guide section 402 and the receiving section 414 open in opposite directions. This allows the receiving section 414 to receive the projection V of the brake carrier 200 and the guide section 402 to receive one of the guide extensions 306, 308 of the brake pad carrier plate 304 (see Fig. 6).

[0050] The width of the centering recess 226 is matched to the shape and / or size of the centering element 416. The width of the centering recess 226 is greater than that of the free end of the centering element 416 projecting into the receiving area AB. As soon as the centering element 416, with its side edges that converge towards the free end of the centering element, rests against the side walls 226a and 226b of the centering recess 226, the guide element 400 is forced into the correct position on the brake carrier 200 and thus automatically aligned.

[0051] The guide element 400 has retaining claws 430 and 432, which serve to fasten the guide element 400 to the brake carrier 200. The retaining claws 430 and 432 are formed on the back surface 406 of the guide 402 and extend in opposite directions. The retaining claw 430 extends towards the receiving section 414 or the receiving area AB. The retaining claw 432, on the other hand, extends towards the contact surface 426. With respect to the fastening device BR, the centering element 416 is arranged in front of the retaining claws 430 and 432 so that the centering or positioning of the guide element 400 is completed before the retaining claws 430 and 432 engage with the brake carrier 200.

[0052] The function of the guide element 400 is briefly explained below. The centering recess 226 of the brake carrier 200, together with the centering element 416, serves to center and position the guide element 400 on the brake carrier 200. The centering element 416 is placed against the projection V of the brake carrier 200 so that it can engage in the centering recess 226. Due to the elasticity of the guide element 400, the trapezoidal centering element 416 is pressed into the centering recess 226 with its reduced end. The trapezoidal shape of the centering element 416 forces the guide element 400 into the correct position on the brake carrier 200. The centering or positioning of the guide element 400 on the brake carrier is already completed before the retaining claws 430, 432 engage the brake carrier 200.

[0053] Fig. Figure 14 shows a perspective partial view of the brake carrier 200 according to a second embodiment. Fig. Figure 14 shows the guides 212 and 214 for the brake pad assemblies 300 and 302. A guide element 400 is attached to the guide 214. The guides 212 and 214 are essentially identical in construction.

[0054] The brake carrier 200 according to the in Fig. The embodiment shown in 14 largely corresponds to that described in relation to Fig. The brake carrier 200 of the first embodiment described in section 7. The only difference between these two embodiments lies in the design of the centering recess 226. The centering recess 226 according to Fig.14 is formed as a groove on the centering surface 224 and extends in the direction of arrow BR along the centering surface 224. The centering recess 226 extends substantially perpendicular to the end face 222. The centering recess 226 extends from the end face 222 along the centering surface 224. The centering recess 226 has two parallel side walls 226a and 226b, which extend from the end face 222 at an angle of substantially 90° to the end face 222. The centering recess 226 thus has an opening 226e at the end face 222 and an end wall 226c that connects the side walls 226a and 226b. The two side walls 226a and 226b define the width of the centering recess 226 between them. The centering recess 226 extends from the end face 222 or...from the opening 226e on the end face 222 to the end wall 226d, wherein the length of the centering recess 226 is defined between the end face 222 and the end wall 226d.

[0055] Through the opening 226e of the centering recess 226, the centering element 416 of the guide element 400 can engage with the centering recess 226 immediately upon placing the guide element 400 onto the projection V of the brake carrier 200, thus guiding the guide element 400 into its correct position on the brake carrier 200. The attachment of the guide element 400 to the brake carrier is therefore possible without any additional pivoting movement or similar action, further simplifying assembly.

[0056] With the centering element 416 according to the invention, the guide element 400 can be quickly and easily attached in the correct position to the projection V of the brake carrier 200 without assembly errors occurring.
