A drum brake having a brake drum, brake shoes, a carrier plate and a load measurement device in the region of an abutment is mountable on a steering knuckle. The abutment has a cylinder in which two pistons are guided, on the outer end faces of which the abutment ends of the brake shoes rest and the inner end faces of which are each supported by a spring on a step in the cylinder. A hollow peg projects from the outside of the cylinder and penetrates an opening in the carrier plate, such that it can be received in a receiving space in the steering knuckle resting on the carrier plate or in a reinforcement element fixed on the steering knuckle.

Drum brake having a load measurement device

The proposal is for an improved expansion device for a drum brake having an integrated readjustment unit having a readjusting screw which can be locked therein by a spring-loaded latching unit which, for a reliable readjustment function with a reduced level of force, provides for the latching unit to allow a defined idle rotation of the readjusting screw, which is defined structurally by a first stop acting in a first direction of revolution and a second stop acting in the opposite direction of revolution.

Expansion device having a readjustment unit for a drum brake

A brake device having a hydraulic booster stage for a hydraulic motor vehicle brake system is provided, which brake device, within normal boosting operation, can be operated both in an autonomous, driver-independent actuation mode with electronic control and in a manual actuation mode controlled by the driver, and outside normal boosting operation, can be operated in an emergency mode with a non-boosted actuation force generated by the driver alone, in the case of which brake device it is proposed that, within normal boosting operation, each actuation mode is assigned a dedicated piston in a booster housing of the booster stage, which piston is acted on directly with the boosting force and transmits this mechanically to components connected functionally downstream.

Brake device for a hydraulic motor vehicle brake system

A modular braking device for a hydraulic motor vehicle brake system, which is optimized for remote actuation, including a hydraulic booster stage with a booster housing, a main brake cylinder mounted thereon, a booster piston which is displaceable therein and delimits a pressure chamber which is supplied directly with pressure medium by a motor pump unit.

Braking device for a hydraulic motor vehicle brake system

A simple, compact, and economical motor/pump unit for supplying vacuum to a pneumatic brake booster of a motor-vehicle brake system, wherein the motor/pump unit is designed as a diaphragm pump having a single elastomeric diaphragm, which is moved by an electrically operated motor unit by an eccentric drive, and has a pump housing and a working-space cover and the diaphragm is clamped between the pump housing and the working-space cover at the radial outer edge of the diaphragm in a sealing manner and the working-space cover is designed as a multi-part working-space cover having an upper cover, a lower cover, and an inlet valve and an outlet valve, which are arranged between the upper cover and the lower cover and control the air circulation through the working space.

Motor/pump unit having a single elastic diaphragm

The invention relates to a pump unit that can be driven by an electric motor, in particular for providing vacuum for a pneumatic brake booster, including a pump housing that can be closed by a working-chamber cover and at least one elastic displacement element, wherein a working chamber is bounded between the displacement element and the working-chamber cover and wherein inlet valves and outlet valves and inlet channels and outlet channels associated with the valves are associated with the working chamber. According to the invention, in order to reduce noise emissions, devices for reducing a contact surface between the working-chamber cover and the pump housing are provided.

Pump unit driven by an electric motor

A pump assembly for supplying negative pressure to a pneumatic brake booster, wherein the pump assembly has at least two elastic displacement elements which are moved by connecting rods, the connecting rods each being rotatably mounted on an eccentric element. The eccentric element has a bearing seat element and a force element. At least two eccentric elements are secured next to each other on a drive shaft that rotates about an axis of rotation and an interlocking anti-rotation device is provided that determines a defined angular position of the eccentric elements relative to each other about the axis of rotation. In order to improve the ease of assembly and simplify the manufacturability, the anti-rotation device is designed as shaped elements of the bearing seat element in such a way that they engage in each other in an interlocking manner when the eccentric elements are in a defined angular position relative to each other.
