Abstract: 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.

Abstract: The invention relates to a travel limiting element in a brake booster device for a motor vehicle brake system, comprising a pair of longitudinal legs which are connected together via at least one transverse leg, wherein the travel limiting element can be brought into contact with a stop of the brake booster device. In favor of a simple design and cost-effective production, the travel limiting element comprises two dimensionally stable reinforcement braces which extend along the longitudinal legs, and the transverse leg is made of a damping material which surrounds the two longitudinal legs at least in sections.

Abstract: A vacuum brake booster (1) has a vacuum chamber (4) and a working chamber (3), which are separated from one another in a pressure-proof manner by a movable wall (5). A control valve (6), which has a housing (7) workingly coupled to the movable wall (5), has a valve seat (10), which is disposed in the housing (7) and which in dependence upon the displacement of an input element (8) may control the supply of at least atmospheric pressure to the working chamber (3) in order to achieve a pressure difference at the movable wall (5). For improved braking force assistance during emergency braking operations, an armature (18) cooperating with a permanent magnet (19) is provided in the control valve housing (7) and coupled in actuating direction to the actuating element (8). The armature (18) is spring-biased counter to actuating direction and, in the normal position of the control valve (6), is held at a first distance from the permanent magnet (19).

Abstract: A vacuum brake booster (1) having a control valve (6) with a housing (7) workingly coupled to a movable wall (5) is described. For improved braking force assistance during emergency braking operations an armature (18) cooperating with a permanent magnet (19) is provided in the control valve housing (7) and coupled in actuating direction to an actuating element (8). The armature (18) is spring-biased counter to actuating direction. For adjusting the distance between the armature (18) and the permanent magnet (19) in the non-actuated state of the vacuum brake booster (1), the axial position of the permanent magnet (19) relative to the control valve housing (7) and/or the distance between the armature (18) and a valve seat (10) is adjustable.
