A disk brake with lower cost and improved maintainability is provided. The brake caliper includes at least one actuating device for actuating the disc brake using a moveably guided bridge. The bridge has at least one threaded hole into which an actuating spindle is displaceably located. A brake disk end of the actuating spindle penetrates a caliper closing plate facing the brake disk. The positioning spindle carries a rotatably-mounted pressure piece which presses a brake pad against the brake disc. The opening is sealed by a bellows retained on the brake caliper on one side and on the pressure piece on the other side. A securing ring non-rotatably located on the actuating spindle and rotatably connected to the thrust piece interacts with the bellows during brake application and/or release to maintain a desired air gap between the brake disk and brake pad.

A brake assembly comprising: (a) a caliper including: (i) one or more pistons, (b) one or more rotary to linear actuators that provides an axial force to move the one or more pistons, (c) a motor gear unit in communication with the one or more rotary to linear actuators, the motor gear unit including: (i) a motor, and (ii) an electromagnetic brake that prevents movement of the motor gear unit, the pistons, or both when the motor is turned off so that the brake apply is maintained.

Provided is an electric braking device that transmits power generated by an electric motor MTR to a pressing member PSN and causes pressing force to be generated by the pressing member PSN with respect to a friction member MSB. Hysteresis characteristics in the relation between the power supply amount to the electric motor and the pressing force of the pressing member are detected each time a predetermined point in time arrives. Upon determination of a “holding state in which the pressing force is held constant”, a minimum value for a power supply amount that makes it possible to maintain the current pressing force is obtained on the basis of the most recently detected hysteresis characteristics and the power supply amount is set to a value determined on the basis of the obtained minimum value for the power supply amount.

The invention relates to a vehicle brake, in particular a utility vehicle disc brake, having a brake carrier with at least one brake pad holder, at least one brake pad which is guided so as to be axially displaceable and supported in the brake pad holder, and a brake caliper which is axially movable relative to the brake carrier. According to the invention, it is proposed that the brake carrier is structurally reinforced on the run-out side relative to the run-in side, and at least one running direction indicator for indicating the first rotational direction is arranged on the brake carrier.

An electro-hydraulic hybrid braking system for a vehicle is disclosed. The system includes multiple wheel-end braking modules (1), a hydraulic control module (2), a first electronic control module (3), and a second electronic control module (4). Each of the wheel-end braking modules (1) includes a hydraulic piston (10), a motor (8), and a speed-reducing transmission mechanism (9) configured to convert a rotary motion from the motor (8) into a linear motion for driving the hydraulic piston (10) or brake friction plates (12) to move forwards. The hydraulic piston (10) is movably arranged, and is movable forwards through brake hydraulic pressure. The motor (8) is controlled by the first electronic control module (3) and/or the second electronic control module (4). The electro-hydraulic hybrid braking system for a vehicle is applicable to a vehicle braking system for intelligent driving.

A bearing assembly for a brake carrier for a utility vehicle, includes a retaining element and a brake support element, wherein the retaining element is fixed to an axle or a chassis component by form fit, substance bonding and/or force fit, wherein the axle extends along an axial direction, wherein the brake support element has a first mounting region, wherein the retaining element has a first retaining region, and wherein the first mounting region is configured to be brought into direct or indirect engagement with the first retaining region such that a displacement along a first transverse direction between the retaining element and brake support element is prevented by form fit.

Disclosed herein a caliper brake includes a carrier in which a pair of pad plates are installed to move forward and backward toward a disk; a caliper housing slidably installed on the carrier and provided with a cylinder; a piston installed in the cylinder and configured to move forward and backward toward the pair of pad plates by a braking hydraulic pressure; a seal groove formed to be recessed in an annular shape on an inner surface of the cylinder; and a seal member accommodated in the seal groove, the seal member including a front surface located in a forward direction of the piston; wherein the front surface is provided with a protrusion from which at least a part thereof protrudes.

This disc brake includes a mounting member, a pair of brake pads, a caliper, a cover member, and a locking member. The caliper includes a cylinder part having a cylinder hole in which a piston for moving one of the pair of brake pads is disposed, a bridge part extending across an outer circumferential surface of a disc from the cylinder part, a plurality of claw parts formed on an extended distal end side of the bridge part and disposed to face the cylinder part, and a recessed part provided between the plurality of claw parts, having an opening at a disc radial direction inner end, and formed to face the cylinder hole. The locking member includes a fixing part fixed to the cover member, and a plurality of locking pieces extending from the fixing part in a direction inclined with respect to a movement direction of the piston.

Flat mount brake calipers for bicycles are described herein. An example flat mount brake caliper includes a caliper body defining a first piston cylinder and a second piston cylinder. The caliper body has a flat mount surface with a first threaded bore and a second threaded bore extending into the flat mount surface. The first and second threaded bores are configured to receive threaded fasteners to couple the caliper body to a frame of the bicycle. The first and second piston cylinders are arranged such that projections of the first and second threaded bores do not intersect the first or second piston cylinders. The flat mount brake caliper also includes a brake pad and first and second pistons disposed in the respective first and second piston cylinders to move the brake pad relative to the caliper body.

A pull rod device arrangement of a brake caliper includes a pull rod top, a pull rod bottom, and two vertical rods, wherein the pull rod top and the pull rod bottom of the pull rod device are connected to each other. The pull rod top and the pull rod bottom of the pull rod device are designed as separate parts. A brake caliper includes the pull rod device.
