A brake adjusting device is mountable to a frame and a rotary disc of a cable reel and includes a rotary knob mounted to an outside surface of the frame. A first pad is arranged between the frame and the rotary disc and is coupled to the rotary knob for synchronous rotation therewith and includes pushing parts in the form of slope. A second pad is arranged between the first pad and the rotary disc and is provided, on two opposite surfaces thereof, with first and second slope sections and friction plates. The rotary knob is operable to rotate the first pad for causing the pushing parts to press against first and second slope sections in order to move the second pad toward the rotary disc and causing the friction plates to get into tight engagement with the rotary disc to result in a braking effect.

A drive device for a braking system of a motor vehicle. The drive device includes a housing and an electric machine that includes a rotatably supported drive shaft. The drive shaft is connected or connectable to an actuator element of the braking system via a planet wheel gear situated in the housing.

An actuator assembly for an electromechanical vehicle brake is disclosed, having a carrier assembly with a frame part, and a guide part in which an actuating slide for a brake pad is mounted so as to be linearly displaceable. The guide part has a rotational locking geometry by which the guide part is rotationally fixedly received in the frame part by form fit. An electromechanical brake is also proposed.

A friction brake system comprises a first gear unit having a first member and a second member, the first gear unit is configured for converting a rotary motion of the first member into a braking motion of the second member, the first member is configured such that the rotary motion may be driven by an electric motor, the brake system further comprises a second gear unit having a spindle and nut for converting a rotary motion into a linear motion for pad wear compensation, the spindle is connectable to a brake pad, the second member of the first gear unit and the nut of the second gear unit are or may be mechanically coupled such that, during the braking motion, the second member of the first gear unit pushes against the nut of the second gear unit to press the brake pad against a friction surface.

An actuating device for a disc brake may have a piston, and a first ramp-ball motion converter having a first ramp portion axially constrained and actuatable in rotation around and actuating axis. The device may also have a second ramp portion coupled to the piston and a plurality of rolling elements interposed in contact between ramp tracks formed by the first and second ramp portion. The device may also have a second screw and nut motion converter connected between the second ramp portion and the piston. The device may also have a torque limiter that implements a torsional connection of the first ramp portion with the second ramp portion. The torque limiter may also decouple the rotation of the first ramp portion with respect to the second ramp portion about the actuating axis when a predetermined limit torque is exceeded.

An expanding device for actuating one of the brake shoes of a drum brake includes a body of revolution and transmission bodies actuated by the body of revolution via ball track ramps. A spacer body is located between two partial bodies of the body of revolution, the spacer body guided by an adjustment spring keeping the partial bodies at the respectively reached distance. The spacer body is screwed onto a pin on the first partial body. A readjustment nut ensures that, when the two partial bodies are pushed apart, the spacer body rotates on the pin and moves away from a supporting surface on a partition of the second partial body. Upon renewed actuation of the brakes, the readjustment nut is guided such that the spacer body bears against the second partial body), but takes up a different position on the pin, the position corresponding to the air clearance readjustment.

A magnetic load sensor unit (1) is provided which can detect the magnitude of an axial load applied by a linear motion actuator (14) to a friction pad (22). The magnetic load sensor unit (1) includes a magnetic target (4) which generates a magnetic field, and a magnetic sensor (5) designed to move relative to the magnetic target (4) corresponding to the axial load.
