A spindle nut assembly for an electric parking brake has a spindle and a spindle nut. The spindle has a plurality of spindle stops and a plurality of external threads. The plurality of external threads has at least two threads. The spindle nut is operatively connected to the spindle, has a plurality of stop cams, and has a plurality of internal threads. At least one of the plurality of stop cams is engaged with at least one of the plurality of spindle stops when a first thread of the plurality of internal threads is started on any external thread of the plurality of external threads.

Spindle nut assembly having multiple stop cams

A motor vehicle brake, in particular a combined hydraulically and electromechanically actuatable motor vehicle brake, with an actuator assembly comprising: a housing, an actuator which can be moved relative to the housing for hydraulically or electromechanically moving a brake lining, a motor drive, a movement mechanism which is arranged between the motor drive and the movable actuator, a gear arrangement which is paired with the movement mechanism, and a separate self-locking device which is designed to block the movement mechanism when necessary, wherein the movement mechanism has a ball screw drive with a rotatable spindle and a nut which can be moved in the housing in a linear manner. The nut can be moved within the housing in order to move the actuator by rotating the spindle, and the gear arrangement has at least two gear stages. In the motor vehicle brake, the self-locking device is arranged in or on the gear arrangement such that at least two gear stages are arranged between the ball screw drive and the self-locking device.

Electromechanically and hydraulically actuatable motor vehicle brake with selective self-locking

An actuating device is specified for an electromechanically actuatable vehicle brake. The device comprises a multi-stage transmission unit, which is arranged between a driving electric motor and a driven drive element of the vehicle brake, wherein at least one stage of the transmission unit is embodied as a spur-gear transmission, and at least two stages of the transmission unit are coupled by means of a double gearwheel, the rotational axis of which extends parallel to the rotational axis of the electric motor. The transmission unit has at least one intermediate stage which is embodied as a spur-gear transmission and into which at least one stage, embodied as a spur-gear transmission, of the transmission unit is integrated.

Actuating device for an electromechanically actuatable vehicle brake

The invention relates to an assembly for a brake actuator which is provided, for example, for an electromechanically operated parking brake. The assembly comprises a drive device and a gear device for generating and transmitting a torque to a brake device, a carrier element having a first mounting device to which the drive device and the gear device are mechanically secured, and a housing having a housing lower portion which has a second mounting device, on which the carrier element together with the drive device and gear device is arranged in a self-supporting manner by means of the first mounting device.

Assembly for an electromechanical brake actuator

An actuator device for use in a land vehicle, comprising an actuator for actuating a wheel brake of the land vehicle, a control unit for controlling the actuator and a processing unit. The processing unit is connected to the control unit and an external main control unit in order to route signals of the main control unit to the control unit. The actuator device further comprises a memory for storing actuator-specific information. This memory is connected to a monitoring unit. The monitoring unit is connected in turn to the control unit and the processing unit.

Actuator device and method for controlling the actuator device

A hydraulic vehicle brake having an optional locking device is described. The locking device is disposed inside a hydraulic chamber that is delimited by a brake piston. For reducing the hydraulic fluid intake, an incompressible filling body is provided inside the hydraulic chamber.
