A disc brake for a motor vehicle having a reset device that can only be plastically deformed, as a result of a force acting thereon in the actuation direction along a guide surface of the receiving region, if the reset device has adopted a predetermined, exclusively elastic deformation as a result of this force, wherein the plastically deformable region is formed as a loop and is in direct contact with the retaining tongue and can also roll out along the guide surface during the plastic deformation.

A disc brake of a floating type includes: an inner pad and an outer pad located on opposite sides of a rotor; a pressing device that presses the inner pad and the outer pad against the rotor; and a housing holding the pressing device. The pressing device includes: a first pressing member movable toward the rotor; a second pressing member movable away from the rotor; and a frame held by the housing via engageable portions movably relative to the housing in a direction parallel with a rotation axis of the rotor. The engageable portions are spaced apart from each other in a circumferential direction of the rotor. The frame is moved with movement of the second pressing member to press the outer pad against the rotor. Each of the engageable portions has a labyrinth structure.

A disc brake of a floating type includes: an inner pad and an outer pad respectively located on opposite sides of a rotor rotatable with a wheel; a pressing device configured to press the inner pad and the outer pad against the rotor; and a housing mounted on a non-rotating member and holding the pressing device. The pressing device includes: a first pressing member movable toward the rotor; a second pressing member movable away from the rotor; and a frame having a substantially frame shape and including (i) a first side portion opposed to the second pressing member and (ii) a second side portion engaged with the outer pad and movable together with the outer pad in a direction parallel with a rotation axis of the rotor. The disc brake includes a return spring provided between the frame and one of the housing and the inner pad.

A brake carrier for a disc brake of a commercial vehicle has an attachment region for fixing on a vehicle axis and at least one pad shaft for receiving and supporting at least one brake pad. The pad shaft is formed by way of an inlet-side carrier horn, an outlet-side carrier horn and a bridge which connects the inlet-side carrier horn and the outlet-side carrier horn. Regions of the bridge which adjoin the carrier horns form bearing surfaces for radially supporting the at least one brake pad. The respective guide contours for guiding the brake pad into a push-in position are arranged to the side of the pad shaft on a side surface of the carrier horns, in which push-in position the brake pad can be pushed axially with respect to the vehicle axle into the pad shaft between the carrier horns.

The present application relates to a friction brake system (1) for a vehicle. The friction brake system (1) comprises a braking member (12) connectable to first and second brake pads and configured for pressing the first and second brake pads against a friction surface. The system (1) further comprises a transmission unit (2) configured for converting a rotary motion generated by an electric motor (30) into a braking motion of the braking member (12). The transmission unit (2) comprises a ball-in-ramp assembly (3) having a first plate (9) with at least one groove (23), a second plate (10) with at least one groove (22) facing the groove (23) of the first plate (9), and at least one ball (11) arranged between the first plate (9) and the second plate (10). The ball (11) is retained by the groove (23) of the first plate (9) and the groove (22) of the second plate (10). Further, the ball-in-ramp (3) assembly is configured to convert a rotary motion of the first plate (9) into a translational motion of the second plate (10) with respect to the first plate (9). The first plate (9) is configured to be rotated by the electric motor (30). Further, at least one of the first plate (9) and the second plate (10) is mechanically coupled with the braking member (12). The first plate (9) is rotatably supported by a brake bolt bracket (16) coupled to a braking bolt (13), and the second plate (10) is operably connected to a caliper housing bolt (14) connected with a caliper housing (33) such that the caliper housing (33) and the braking bolt (14) are configured to press the first and second brake pads against opposing surfaces of a brake disc when the braking member (12) executes the braking motion.

A utility vehicle disk brake includes a vehicle-mounted brake carrier that partially surrounds a brake disk, and a brake caliper that is arranged on and partially covers the brake carrier. Sliding guides allow the brake caliper to slide relative to the brake carrier perpendicularly to a friction surface of the brake disk. A first one of the sliding guides is designed as a fixed bearing, and a second one of the sliding guides is designed as a floating bearing. At least the floating bearing is designed as a slotted guide having a guideway that runs in the sliding direction of the brake caliper as well as a first guiding element that is accommodated in the guideway.

A drive unit a drive unit which can prevent an occurrence of an unintentional relative rotation between the right and the left wheels is provided. The drive unit comprises: a first motor connected to the first driveshaft and a second motor connected to the second drive shaft; a first torque transmitting route between the first motor and the first drive shaft; a second torque transmitting route between the second motor and the second drive shaft; a first rotary member arranged in the first torque transmitting route; a second rotary member arranged in the second torque transmitting route; and a restriction device that restricts a differential rotation between the first rotary member and the second rotary member.

A drive unit having a downsized brake device for applying a braking force to a drive wheel is provided. The drive unit comprises: a first brake device that applies braking torque to a first rotary member situated closer to a first motor than a first speed reducing device in a first torque transmitting route between the first motor and a first drive shaft; and a second brake device that applies braking torque to a second rotary member situated closer to a second motor than a second speed reducing device in a second torque transmitting route between the second motor and a second drive shaft.

A brake carrier for receiving brake pads for a disc brake with a brake disc includes a clamping-side bridge strut on a clamping side of the disc brake, and a reaction-side bridge strut on a reaction side of the disc brake arranged parallel to a brake carrier axis. The clamping-side bridge strut and the reaction-side bridge strut are connected together via a first connecting web at a first end of the brake carrier. Also, the clamping-side bridge strut and the reaction-side bridge strut are connected together via a second connecting web at a second end of the brake carrier. The brake carrier has a brake pad receiving side provided with brake carrier horns, and a brake carrier underside.

A brake carrier is provided for a disc brake having at least one brake pad, wherein the brake carrier includes: a wrap-around disc holder that wraps around a section of a brake disc of the disc brake in a frame-like manner; at least one brake pad slot in which the brake carrier guides the at least one brake pad, wherein the at least one pad slot is formed by carrier lugs, support surfaces and bridge struts on the wrap-around disc holder. The brake carrier is produced as a single piece using a shaping method and has a mold partition burr. The mold partition burr is arranged outside of the wrap-around disc holder.
