The invention relates to an electronically adjustable brake unit for motor vehicles, comprising a pressure generating device for creating a hydraulic pressure and the corresponding drive device. Said brake unit operates particularly quietly and is optimally embodied for the reduction of radial forces on the motor bearing, whereby the pressure generating device is an internal gear pump (4). The internal gear pump (4) is preferably constructed in the form of a cassette and mounted in the valve block (1) by means of a clinch connection.

The invention relates to an electronically controllable brake actuating system for motor vehicles, comprising an unpressurized pressure medium reservoir (3), a pressure source (20) which can be controlled by means of an electronic control unit (38) and whose pressure allows for activation of the wheel brakes (7, 8, 9, 10) of the motor vehicle, and a device (13, 36) for detecting the intention of the driver to slow down as well as valve units (27, 28) which are mounted upstream of the wheel brakes (7 - 10) and optionally connect the wheel brakes (8 - 10) with the pressure source (20) or the pressure medium reservoir (3). To improve the operational and functional reliability of such a system the invention provides for means (33, 34, 35, 39, 40, 41, 49, 50) for detecting gases and air present in the system.
摘要:
The invention concerns an arrangement for actuating a motor vehicle braking system of the 'brake-by-wire' type, the arrangement comprising an actuating pedal and a path simulator which co-operates with the brake pedal and whose simulator piston is connected for force transmission ot the actuating pedal. The path simulator is also pretensioned by a spring and comprises means of attenuating the movement of the simulator piston as a function of the actuating pedal path. According to the invention, in order to attain effective attenuation, the simulator piston (11) delimits a hydraulic chamber (12) which is connected via at least one variable flow resistance (16, 17, 18, 19, 20) to a second hydraulic chamber (4 or 14).

The invention relates to an electronically adjustable brake actuation system for motor vehicles, comprising a master cylinder (2) with a pressureless hydraulic fluid tank (3), a pressure source (20) which can be controlled by an electronic control unit (32) enabling pressure to be exerted upon the wheel brakes (7, 8, 9, 10) of the motor vehicle. Said brakes can be joined to the master cylinder (2) by at least one hydraulic connection (11, 14) which can be shut off by a block valve (12, 15). The invention is also provided with a device (13, 33) for detecting the driver's desire to decelerate, in addition to at least one separating piston (16) arranged upstream from the wheel brakes (7-10) and whose first chamber (17) can be connected to the master cylinder (2) and whose second chamber 919) can be connected to the pressure source (20) or the hydraulic fluid tank (3) by a valve device (27, 271). In order to improve the dosing of braking pressure in said system, the invention provides that the valve device (27, 271) is formed by a multiposition valve built like a gate valve, and that a switching seat valve (29) is inserted in the joint between the multiposition valve (27, 271) and the pressure source (20).

The invention relates to a pressure sensor assembly, especially for a pressure control device, comprising a supporting housing (3) for accommodating several pressure sensors (4). Said supporting housing (3) accommodates the pressure sensors (4) in the form of a modular assembly which can be pre-tested. This forms a sub-assembly which can be handled independently and which is positionable preferably between a first and second housing (1, 2) of the pressure control device.
