摘要： The invention relates to a brake booster for an automotive brake system with regenerative brake force generation, comprising a force input element that may be or is coupled to a brake pedal, a chamber arrangement having a vacuum chamber and a working chamber that are separated from one another by a movable wall, a control valve, by means of which in accordance with a displacement of the force input element the working chamber is connectable selectively to the vacuum chamber and the atmosphere to generate and reduce a differential pressure at the movable wall, wherein the control valve has a control valve housing that is connected for joint movement to the movable wall In this case, it may be provided that in a first actuation phase of the brake booster from its rest position the force input element is displaceable relative to the control valve housing by an idle travel, in which the control valve remains non-actuated to suppress a build-up of a differential pressure at the movable wall.

摘要： A brake booster with regenerative brake force generation comprising a force input element coupled to a brake pedal. A chamber arrangement having a vacuum chamber and a working chamber that are separated from one another by a movable wall. A control valve actuated in accordance with a displacement of the force input element. The working chamber is connectable selectively to the vacuum chamber and the atmosphere to generate and reduce a differential pressure at the movable wall. The control valve has a control valve housing that is connected for joint movement to the movable wall. In a first actuation phase of the brake booster from its rest position, the force input element is displaceable relative to the control valve housing by an idle travel, in which the control valve remains non-actuated to suppress a build-up of a differential pressure at the movable wall.

摘要： A master cylinder (10) for a vehicle hydraulic brake system has a housing (12) with a bore (14) formed therein, which is open at one end and in which a first pressure piston (16) and a second pressure piston (18) are guided sealingly and displaceably along an axis (A). Acting counter to an actuating direction (X) upon the first pressure piston (16) is a restrained first restoring spring (34) and upon the second pressure piston (18) a second restoring spring (52). In order, in a transportation or disassembly state of the master cylinder (10), to prevent the first pressure piston (16) from being pressed excessively out of the bore (14), the second pressure piston (18) is supported by means of a stop component (66) counter to the actuating direction (X) positively in the housing (12) of the master cylinder (10).

摘要： A vacuum brake booster (10) is described, having a vacuum chamber (16) and a working chamber (18) separated from one another by a movable wall (14), and a control valve (20), which comprises a housing (12) coupled workingly to the movable wall (14) and which to achieve a pressure difference at the movable wall (14) is capable of controlling the supply of atmospheric pressure or above-atmospheric pressure to the working chamber (18) in dependence upon the displacement of an actuating piston (28). The vacuum brake booster (10) has an emergency braking aid comprising a permanent magnet (38) and an armature (36), which cooperates with the permanent magnet (38) and is resiliently biased counter to actuating direction and during an emergency braking operation is drawn into abutment with the permanent magnet (38), with the result that the control valve (20) is held open for the supply of atmospheric pressure to the working chamber (18). The vacuum brake booster (10) comprises a coupling device (90) for detachably coupling the armature (36) to the actuating piston (28).
