Disclosed is a brake actuating unit for actuating a motor vehicle brake system of the 'brake-by-wire' type. The system includes a brake booster which is operable in response to the driver's wish both by a brake pedal and by an electronic control unit. A device is provided to decouple a force-transmitting connection between the brake pedal and the brake booster in the 'brake-by-wire' operating mode. A master brake cylinder connected downstream of the brake booster, a device to detect a deceleration request of the driver, and a pedal travel simulator which interacts with the brake pedal and due to which a resetting force acting on the brake pedal can be simulated in the &#x2018;brake-by-wire&#x2019; operating mode independently of an actuation of the brake booster, and which can be enabled in the &#x2018;brake-by-wire&#x2019; operating mode when the force-transmitting connection between the brake pedal and the brake booster is decoupled and can be disabled outside the &#x2018;brake-by-wire&#x2019; operating mode. The pedal travel simulator () is enabled and disabled by electromechanical means (), electrohydraulic means () or pneumatically operable means (to).

Break actuating unit for actuating a motor vehicle brake system

Disclosed is a brake booster for motor vehicles, the control valve () of which is operable, irrespective of an actuating rod () that displaces a valve piston (), via an electromagnet (), which actuates a third sealing seat () allowing ventilation of the working chamber (). The third sealing seat () is provided on a sleeve () that cooperates with the electromagnet (), and a ring () is arranged, which is displaceable in relation to the third sealing seat () and is supported on the sleeve () by the intermediary of an elastic or compressible element (). In order to improve the dynamics and the sound behavior of the brake booster, the ring () is arranged radially within the sleeve () in such a manner that its areas (), by which it is in contact with the valve body (), at least partly release the passages () provided in the valve body ().

Brake booster for motor vehicles

A pneumatic brake booster for motor vehicles includes a booster housing, subdivided into at least one working chamber and at least one vacuum chamber by at least one axially movable wall to which a pneumatic differential pressure can be applied, a control valve controlling the differential pressure and arranged in a control housing to connect the working chamber to the vacuum chamber or atmosphere, the valve having two concentrically arranged sealing seats and an elastically deformable valve member, an operable input member connected to a valve piston whose movement is limited by a transverse member that can be introduced in a radial direction into the control housing, an elastic reaction element, an output member applying a boosting force to a master cylinder, and ventilating and bleeding ducts in the control housing.
