Description

Technical Field

[0001] The present disclosure relates to a sliding bearing component of a clamping device for a disc brake of a vehicle, in particular a commercial vehicle. The present disclosure also relates to a brake caliper for accommodating a clamping device for a disc brake of a vehicle, in particular a commercial vehicle, a disc brake for a vehicle, in particular a commercial vehicle, comprising a sliding bearing component and a brake caliper, and a vehicle, in particular a commercial vehicle, comprising a disc brake. Background Art

[0002] Such a disk brake is known from the prior art. Such a disk brake has a clamping device. In this case, a so-called sliding block can be provided as a sliding bearing component and a rod bearing can be provided as components of the clamping device that can be operatively connected to each other. Such sliding bearing components are known from the prior art. According to the prior art, in particular in compressed air disk brakes, functional surfaces, in particular sliding surfaces, are realized by using such components and, in the case of a rod bearing, usually have the function of reducing the sliding friction between the sliding partners of the rod bearing.

[0003] EP 3 109 499 A1 discloses a disc brake, in particular a disc brake for commercial vehicles, which has a brake disc, a brake shaft (whose axis of rotation is parallel to the main plane of the brake disc), a brake lining located on the same side as the brake shaft relative to the brake disc, a pressure piece between the brake shaft and the brake lining, a first limiting device that limits the movability of the pressure piece relative to the brake disc in a direction parallel to the axis of rotation of the brake shaft to a predetermined first degree, and a second limiting device that limits the movability of the brake shaft relative to the brake disc in a direction parallel to the axis of rotation of the brake shaft to a predetermined second degree, wherein the brake shaft, when actuated, causes the pressure piece and thus the brake lining to press against the brake disc. The second limiting device has a first stop on the pressure piece and a second stop on the brake shaft, the second stop cooperating with the first stop in the sense of limiting the movability. The support of the brake shaft on the brake caliper can be designed in principle in any manner and method. The support can also be realized via a slide. Such a slide can avoid the blocking of elements involved in the brake clamping by corresponding sliding, if necessary. Furthermore, a third limiting device can be provided, which limits the mobility of the slide relative to the brake disk in at least one direction parallel to the main plane of the brake disk to a predetermined third extent. Such a limiting device can be particularly useful in the installation of the brake, i.e., for example, as a means of preventing the slide from being lost. It can be provided that the third limiting device has a projection, which projects into the recess in the installed state.

[0004] EP 3 499 071 A1 discloses a clamping device for a disc brake, in particular for a sliding caliper disc brake, for clamping a brake disc. The disc brake has at least one brake caliper for accommodating the clamping device and a brake lining for clamping the brake disc. In addition, the clamping device comprises a clamping lever with at least one clamping lever leg. The clamping lever leg has a recess for accommodating a bearing shell in the direction of the side facing the brake lining or the side facing away from the brake lining. The clamping lever is arranged inside the brake caliper of the disc brake and is supported on the inner wall of the brake caliper on the side facing away from the brake lining via two slide blocks.

[0005] The fastening of the sliding block as a sliding bearing component is reliable. However, the production of the sliding block and / or the inner wall of the brake caliper on which the sliding block is supported is relatively complex due to the geometry of the sliding block: that is, the sliding block essentially has an arc-shaped cross section, that is, without taking into account the limiting device. The sliding block thus has a cross section that is bounded by a curved circular arc and a flat circular chord. As a result, the production of such a sliding bearing component has improved cost efficiency. Summary of the invention

[0006] The object of the present disclosure is to enrich the prior art and at least partially improve the above-mentioned aspects. In particular, the present disclosure solves the object of being able to provide an alternative plain bearing component, which enables a more efficient production of the alternative plain bearing component and / or the friction partner.

[0007] According to one aspect of the present disclosure, a sliding bearing component of a clamping device for a disc brake of a vehicle, in particular a commercial vehicle, is provided, wherein the sliding bearing component has a peripheral side surface, the peripheral side surface has a partially circular cross-section, and the sliding bearing component has a limiting element arranged on the peripheral side surface on the sliding bearing component side for limiting the movability of the sliding bearing component.

[0008] It has been recognized that the production of the plain bearing component can be more efficient if the lateral surface has a partially circular cross section. Due to the fully circular cross section of the plain bearing component or thus the partially cylindrical shape, the plain bearing component can be produced significantly more efficiently.

[0009] In order to limit and / or avoid the movement of the sliding bearing component reliably as in the prior art, the sliding bearing component has a limiting element on the sliding bearing component side for limiting the mobility of the sliding bearing component. For this purpose, the limiting element can be operatively connected to the limiting element on the brake caliper side.

[0010] Optionally, the limiting element on the sliding bearing part side has a partially circular cross section. Therefore, efficient production of the limiting element is possible. The limiting element can protrude radially from the peripheral side so that it can be operatively connected to the limiting element on the brake caliper side. The limiting element can be a bolt protruding from the peripheral side.

[0011] Optionally, the sliding bearing component has a cylindrical body, and the limiting element on the sliding bearing component side is welded to the body and / or connected to the body in a force-locking manner. Therefore, a safe and reliable connection between the body and the limiting element on the sliding bearing component side can be achieved. By welding, the limiting element on the sliding bearing component side can be arranged on the peripheral side. For the force-locking connection, the body can have an opening, and the limiting element on the sliding bearing component side is at least partially pressed into and thus fixed in the opening. After pressing in, a clamping force can act between the limiting element on the sliding bearing component side and the opening in the body, and the clamping force can achieve a reliable fastening of the limiting element on the sliding bearing component side in the opening.

[0012] Optionally, the plain bearing part has a longitudinal axis and the plain bearing part has a completely circular cross section in a section defined along the longitudinal axis. In this case, the section can be arranged in particular outside the limiting element on the plain bearing part side, as seen in the direction of the longitudinal axis. The plain bearing part is thus cylindrical in this section. Outside of this section, the shape can deviate from the cylindrical shape due to the limiting element on the plain bearing part side.

[0013] According to one aspect of the present disclosure, a brake caliper for accommodating a clamping device for a disc brake of a vehicle, in particular a commercial vehicle, is provided, wherein the brake caliper has a base section for arranging a sliding bearing component, the base section has a recess, the recess is designed to accommodate a circumferential side of the sliding bearing component, and the base section has a limiting element on the brake caliper side for limiting the movability of the sliding bearing component, wherein the limiting element on the brake caliper side is designed to be operatively connected to the limiting element on the sliding bearing component side for limiting the movability of the sliding bearing component relative to the base section, wherein the recess is partially cylindrical and / or is defined by two planes.

[0014] A brake caliper having a base section with a recess can effectively support the plain bearing component. In this case, the recess can be partially cylindrical and have a shape that matches the circumferential surface of the body of the plain bearing component. Alternatively or additionally, the recess can also be defined by two planes, in particular planes that are parallel to each other. The planes define a U-shaped recess or pocket, in which the plain bearing component can be at least partially arranged.

[0015] Optionally, the limiting element on the brake caliper side is a partially circular pocket. Therefore, the limiting element on the sliding bearing component side, in particular the limiting element on the sliding bearing component side having a fully circular cross section, can be effectively and reliably operatively connected to the limiting element on the brake caliper side in order to reliably reduce and / or avoid movement of the sliding bearing component.

[0016] Optionally, the recess has a longitudinal axis, along which the base section extends. Thus, the plain bearing component with the lateral surface can be arranged and oriented on the base section in a clearly defined and secure manner.

[0017] According to one aspect of the present disclosure, a disc brake for a vehicle, in particular a commercial vehicle, is provided, which includes the above-mentioned sliding bearing component and the above-mentioned brake caliper. Optionally, the disc brake or the sliding bearing component and / or the brake caliper include one or more of the above-mentioned features to achieve relevant technical effects.

[0018] According to one aspect of the present disclosure, a vehicle, in particular a commercial vehicle, is provided, which includes the above-mentioned disc brake. Optionally, the disc brake of the vehicle, in particular a commercial vehicle, includes one or more of the above-mentioned features to achieve relevant technical effects.

[0028] Figure 1 A schematic diagram of a vehicle 200a, in particular a commercial vehicle 200b, according to one aspect of the present disclosure is shown. The vehicle 200a, in particular the commercial vehicle 200b, is subsequently referred to as the vehicle 200a, 200b. The vehicle 200a, 200b is a land vehicle, such as a tractor and / or trailer of a multi-section vehicle and / or a bus.

[0029] The vehicle 200a, 200b comprises a disc brake 220. The disc brake 220 is pneumatically and / or electropneumatically actuatable and is designed to decelerate the movement of the vehicle 200a, 200b or to brake the vehicle 200a, 200b. To this end, the disc brake 220 can realize a braking torque acting on one or more wheels (not shown) of the vehicle 200a, 200b. For this purpose, the disc brake 220 comprises a clamping device 250 (see Figure 2 and Figure 5 ), which is used to clamp the brake linings on the brake disks (not shown in each case) as friction partners that can be operatively connected to each other for decelerating the vehicles 200a, 200b. For this purpose, the disk brake 220 includes a sliding bearing component 100 and a brake caliper 150.

[0030] The brake caliper 150 can be designed in particular as a floating and / or sliding caliper and thus can be mounted movably relative to the brake disk. In other specific embodiments, the brake caliper 150 can be designed as a fixed caliper and can be arranged in a fixed position relative to the brake disk.

[0034] The clamping device 250 comprises a rod (not shown) having a rod leg 260. On the rod leg 260 a bearing housing 261 is arranged or fastened.

[0035] The clamping device 250 or the disk brake 220 comprises a sliding bearing component 100 which is designed as a slide. The sliding bearing component 100 and the lever leg 260 or the bearing shell 261 are designed to be operatively connected to each other so as to enable the lever leg 260 to be rotatably supported and thus to enable the lever leg 260 to rotate around the sliding bearing component 100.

[0036] The sliding bearing component 100 comprises a main body 105 which can be in mechanical contact with the bearing shell 261 and a limiting element 120 on the sliding bearing component side for limiting the movability of the sliding bearing component 100. The sliding bearing component 100 has a main body 105 with a partially circular cross section, as in Figure 2 As can be seen in the cross-sectional view in , and therefore has a partially cylindrical profile with partially cylindrical and locally flat surfaces.

[0037] The disc brake 220 comprises a brake caliper 150 for accommodating a clamping device 250. For this purpose, the brake caliper 150 has a base section 155 for arranging the sliding bearing component 100. The sliding bearing component 100 and the base section 155 are designed to be operatively connected to each other in order to support the sliding bearing component 100 on the base section 155. Accordingly, the base section 155 is defined by a plane 171, on which the sliding bearing component 100 can be supported, in particular, by means of a locally planar surface of the sliding bearing 100.

[0038] The base section 155 has a caliper-side limiting element 165 for limiting the mobility of the plain bearing part 100. The caliper-side limiting element 165 is a depression or pocket 170 within the base section 155. The caliper-side limiting element 165 is designed to be brought into operative connection with the plain bearing part-side limiting element 120 in order to limit the mobility of the plain bearing part 100 relative to the base section 155. The plain bearing part-side limiting element 120 is a pin that can be introduced into the pocket 170 in order to hold the plain bearing part 100.

[0042] The sliding bearing component 100 has a peripheral side surface 110 having a partially circular cross section 115. Figure 5 In the cross-sectional view shown, the cross section 155 is completely circular, ie a perfect circle, except for the limiting element 120 on the plain bearing part side. Therefore, except for the limiting element 120 on the plain bearing part side, the plain bearing part 100 is cylindrical.

[0043] The sliding bearing component 100 has a limiting element 120 arranged on the sliding bearing component side on the lateral surface 110 for limiting the mobility of the sliding bearing component 100. The limiting element 120 on the sliding bearing component side has a partially circular cross section 125 (see also Figure 7 ). The limiting element 120 is a pin or a bolt protruding from the peripheral side surface 110 .

[0044] The plain bearing component 100 has a cylindrical body 105, and the limiting element 120 on the plain bearing component side is welded to the body 105 and / or connected to the body 105 in a force-fitting manner. For example, the limiting element 120 on the plain bearing component side is a pin or a bolt pressed into an opening (not shown) of the plain bearing component 100.

[0045] The sliding bearing component 100 has a longitudinal axis L. Figure 5 In the illustration shown, the longitudinal axis L extends into the image plane, as schematically indicated by a cross.

[0046] The base section 155 has a recess 160. The recess 160 is designed to accommodate the circumferential side surface 110 of the sliding bearing component 100.
