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

It is known in the art to apply a counterforce, which opposes the actuating force, onto an accelerator pedal of a vehicle in the event that the vehicle, with respect to a vehicle parameter, sufficiently deviates from the nominal value. The parameter can be the speed or the measured distance from vehicles driving ahead. The invention discloses a series of embodiments that satisfy especially easily and reliably the defined requirements for applying the counterforce to the pedal.

The invention relates to a master cylinder with a pressure chamber formed in a housing of the master cylinder and a reservoir bore for accommodating a pressure fluid reservoir, a valve with a closing element being provided which due to a pressure difference prevailing between the pressure chamber and the pressure fluid reservoir can be moved into an opening position or a closing position, the valve in its opening position allowing a pressure fluid flow from the pressure fluid reservoir into the pressure chamber and throttling or preventing, in its closing position, a pressure fluid flow from the pressure chamber into the pressure fluid reservoir. Means are provided which maintain the closing body in its opening position when it is acted upon by a closing pressure difference during vacuum filling of the brake system.

Master cylinder

Vacuum brake booster for motor vehicles comprising a booster housing whose interior is subdivided by a movable wall into a vacuum chamber and a working chamber, a control valve that controls a pressure difference acting upon the movable wall and is accommodated in a control housing that carries the movable wall, said control valve being composed of two concentrically arranged sealing seats and an elastically deformable valve member, wherein the control housing includes a cavity through which a cross member extends and delimits the axial movability of a valve piston relative to the control housing, and the cross member includes at least one projection made of an elastic material in the area where the cross member rests against the booster housing. At least one projection made of an elastic material is provided in the area of points of abutment between the control housing and the cross member.
