A spreader unit for a drum brake is provided with a readjustment device which ensures that the clearance remains substantially constant even in the case of wear on the brake linings. The readjustment device is arranged between actuating pistons and changes the spacing of the actuating pistons in at least one readjustment step when an actuating travel of the first and second brake shoe holders has exceeded a travel setpoint value. A thermally actuable blocking device mechanically prevents the execution of the readjustment step by the readjustment device at a temperature above a temperature setpoint value

A multi-disk brake (1) for a motor vehicle has two multi-disk mechanisms (7, 8) and an actuation device (9) for brake actuation and/or brake release of the multi-disk mechanisms (7, 8), and an electric drive (16) for translational actuation (spreading) of the actuation device, such as, in particular, the ramp unit (9). During a spreading operation, the multi-disk mechanisms (7, 8) are pretensioned in a metered manner by the actuation device and produce a desired frictional engagement, and a correspondingly reversed activation of the actuating mechanism enables a correspondingly metered brake release. By means of the electric drive (16), the action of the multi-disk brake (1) can be metered overall in a particularly precise, sensitive and compensated manner in modern vehicle topology, including all peripheral brake components and systems, including recuperation.

Left front electric brake mechanisms apply a braking force to a left front wheel by actuating an “electric motor of a first left front electric brake mechanism” and an “electric motor of a second left front electric brake mechanism” controllable independently of each other. A first ECU (a control portion) acquires a target thrust force instruction value to be generated on the left front electric brake mechanisms based on a target braking force to be applied to the left front wheel. The first ECU (the control portion) outputs a first control instruction for actuating the electric motor of the first left front electric brake mechanism and a second control instruction for actuating the electric motor of the first left front electric brake mechanism according to a change amount of the target thrust force instruction value.

A wheel and brake disc apparatus of a vehicle includes a roadway wheel and a brake disc mounted rotatably to the vehicle, the roadway wheel and the brake disc arranged about an axis of rotation. The roadway wheel extends radially in relation to the axis of rotation to a wheel rim configured to hold a tire adapted to operate on a roadway surface. The brake disc is inboard of the roadway wheel and extends radially in relation to the axis of rotation to a brake disc rim. A brake caliper assembly mounted at a fixed location over the brake disc rim is configured to squeeze brake pads against the brake disc. The brake disc rim includes a tread configured to operate on a rail without interference from the brake caliper assembly.

A brake apparatus for a vehicle may include: a drive part configured to generate driving power; a pair of pressing parts configured to receive the driving power from the drive part and to apply or release a braking force; a load transmission part installed between the pair of pressing parts and configured to transmit a pressing load of any one of the pair of pressing parts to the other pressing part of the pair of pressing parts; and a load transmission restricting part configured to selectively restrict an operation of the load transmission part by pressing the load transmission part.

An electronic brake system is disclosed. According to one aspect of the present disclosure, there may be provided an electronic brake system including a piston provided in a caliper housing to press a pad plate, a nut coupled to the inside of the piston to move the piston forward or backward, a spindle configured to move the nut forward or backward by rotation and including a stepped portion formed on an outer surface thereof, a rotation limit unit connected to or disconnected from the spindle to allow or block the rotation of the spindle, and a drive unit configured to move the rotation limit unit to a position at which the rotation of the spindle is allowed or blocked, wherein the rotation limit unit includes a body surrounding an outer circumferential surface of the spindle, a binder provided on the body and provided to come into close contact with the stepped portion, and a connector provided on the body and configured to receive a driving force from the drive unit.

The brake pad for a disk brake includes a lining and a plate. The lining includes:—a friction face and a fastening face;—a rear edge;—an inner edge and an outer edge; and—a collection groove extending into the inner edge or outer edge. The plate has a hole, the hole being connected to a vacuum source via communication element. The lining has a rear region including the rear edge and the collection groove, and a chamfered portion such that an area of a friction surface of the rear region increases when a thickness of the rear region decreases, the collection groove being located at a distance from a free surface of the chamfered portion and having a cross-section which extends obliquely towards the free surface of the chamfered portion.

A disc brake (1) for a utility vehicle includes a brake disc (19), a brake caliper (2) which surrounds the brake disc (19), an application-side brake lining (3), a rim-side brake lining (3a) and an application-side application device (4) which is arranged in the brake caliper (2). The application device (4) has at least one adjustment spindle (5) and a pressure plate (6) that is arranged axially between the adjustment spindle (5) and the application-side brake lining (3). A plain bearing element (7) is arranged between the pressure plate (6) and the adjustment spindle (4).

A method is provided for scheduling regenerative braking torque, including: sensing a position of an accelerator pedal; generating a torque request value in response to the sensed accelerator pedal position; determining a speed of operation of a motor/generator; determining a torque limit in response to the torque request value and the determined speed of the motor/generator; generating a regenerative braking command in response to the torque limit; and outputting the regenerative braking command to the motor/generator.
