A disc brake (10) of the type including a pivoting lever having eccentric journals which act on a pair of tappets is disclosed. The tappets are adjusted in length by rotation, and each tappet has a tappet gear (22). A centrally located intermediate gear (24) is provided between the tappet gears to form a gear train, synchronizing the rotation of the two tappets and therefore ensuring that they remain the same length. The centrally located intermediate gear (24) includes a socket (26) for receiving a centrally located adjuster. The adjuster may be installed and removed from the disc brake through an aperture at the rear of the brake caliper, without any substantial disassembly of the brake and without de-synchronizing the tappets or even interrupting the gear train between the tappets.

A disc brake, preferably a compressed air-actuated disc brake, in particular for a motor vehicle, has a brake application mechanism with a brake rotary lever, at least one spindle unit having a threaded rod screwed into a bridge, and a brake caliper. The caliper frames an edge region of a brake disc. The brake caliper has a brake application portion and a caliper back which are connected together via tie bars. The brake application mechanism with the brake rotary lever is received in the brake application portion of the brake caliper from an application face side of the brake disc. The brake application portion of the brake caliper has a first region, in which the application mechanism and a force transmission portion of the brake rotary lever are arranged, a second region, which is formed as a lever housing, and a lever portion for the brake rotary lever. A support wall with a bearing portion, which forms a pivot bearing with a brake rotary lever axis that runs parallel to the brake disc, for the brake rotary lever is arranged between the first region and the second region.

An adjusting device for a disc brake, in particular for utility vehicles, is provided. The adjusting device includes a freewheel having an inner ring and an outer ring. The inner ring and outer ring together with multiple rolling bearing balls form an axial ball bearing. The inner ring is rotatably supported relative to the outer ring by the rolling bearing balls. The freewheel further has a cage in which multiple clamping rollers are biased with compression springs and compression pieces, the cage being arranged between the inner ring and the outer ring in a radial direction relative to a through-bore passing through the inner and outer rings. The compression springs may be pretensioned by rotating the cage relative to the inner ring and then fixing the cage to on the inner ring with a locking device.

A force transmission device, tappet, and method of manufacture. The tappet may include a shaft portion for transmission of a thrust loading from an actuating member to a piston of a disc brake and a gear portion for transmission of rotary motion to the shaft. The gear portion may be formed as a separate piece from the shaft portion.

A brake assembly that may include a housing assembly, a piston assembly, an operating shaft, and a sensor assembly. The operating shaft may be configured to rotate about an axis to actuate the piston assembly and translate a brake pad assembly from a retracted position to an extended position. The sensor assembly may be configured to detect rotation of the operating shaft.

A disc brake, preferably pneumatically actuated, in particular for a motor vehicle, including a brake disc with a brake disc axis, a brake caliper, in particular a sliding caliper, with a brake application section and a caliper back which are connected via rension struts, and at least two brake pads with in each case one brake pad carrier. Of the brake pads, an application-side brake pad is assigned to the brake application section and a back-side brake pad is assigned to the caliper back. The brake pad carrier of the back-side brake pad and the caliper back of the brake caliper are in contact via at least one pair of contact surfaces. One contact surface of the at least one pair of contact surfaces is an end surface of a projection, and the other contact surface of the at least one pair of contact surfaces is a bottom surface of a recess.

This application provides an electro-mechanical braking system and a vehicle. The electro-mechanical braking system includes a clamp body which includes two sliding blocks, a screw rod, and a gain bridge, one of the sliding blocks is configured to be movably connected to one friction plate and the gain bridge, the gain bridge is configured to drive the friction plate, the other sliding block is configured to be in transmission connection to the sliding block and the other friction plate through the screw rod, and the screw rod is configured to be in threaded connection to the other sliding block. The electro-mechanical braking system includes a driving apparatus which is configured to drive the gain bridge and the sliding block and is configured to drive, through a one-way torque limiting apparatus, the screw rod to rotate along an axis of the screw rod relative to the two sliding blocks.

A brake caliper for a vehicle disc brake including a pair of brake pads, and brake a disc positioned in between the brake pads is provided. The brake caliper includes a thrust piece that is configured to move at least one of the brake pads relative to the brake disc, an adjuster unit in threaded engagement with the thrust piece, and a spring unit operatively coupled to the adjuster unit and the thrust piece. The spring unit has a latching element and the adjuster unit has a corresponding latching interface, wherein the latching element is arranged to engage the latching interface when the adjuster unit is in threaded engagement with the thrust piece, and the spring unit further has a mounting element in engagement with the thrust piece to provide a resistance against a rotational movement the adjuster unit relative to the thrust piece.

A force transmission device for a disc brake operable to move a friction element of the brake into engagement with a rotary brake disc along a first axis in response to a loading from an actuating member, the device comprising: a guide member having a generally cylindrical guide form; a piston comprising a complementary generally cylindrical outer sliding surface slideable within the guide member, wherein; an anti-rotation formation is provided between the guide member and the piston, the formation comprising a recess extending generally parallel to the first axis and a complementary projection.

A method for determining wear of a disc brake that is for braking a rotor, the disc brake configured to clamp an inner brake pad and an outer brake pad onto the rotor and the disc brake including a carrier, a caliper housing, and an adjuster configured to adjust position of the inner brake pad and/or the outer brake pad. The method includes sensing linear movement of the caliper housing relative to the carrier, sensing rotary movement of the adjuster, determining outer brake pad wear based on the linear movement of the caliper housing relative to the carrier, and determining inner brake pad wear based on the rotary movement of the adjuster.
