Hydraulic assembly for a vehicle brake system

摘要

A hydraulic assembly for a vehicle brake system comprising at least two brake circuits and wheel brakes associated with the brake circuits. The hydraulic assembly comprises a pressure generator for generating a central hydraulic pressure for the brake circuits independently of the driver at least in the case of service braking initiated by the driver. Furthermore, at least one pressure adjusting device is provided for adjusting for each individual brake circuit the central hydraulic pressure that is generated by the pressure generator independently of the driver.

1. Hydraulic assembly for a vehicle brake system comprising at least two brake circuits and wheel brakes associated with the brake circuits, the hydraulic assembly comprising:
a pressure generator for generating a central hydraulic pressure for the brake circuits independently of a driver at least during a service braking operation initiated by a driver; and at least one pressure adjuster for adjusting for each individual brake circuit the central hydraulic pressure generated by the pressure generator independently of the driver, wherein the at least one pressure adjuster comprises a first valve device, the first valve device comprising at least one adjusting valve, which is adjustable at least between an open valve position and a closed valve position, and a first non-return valve, which is connected in parallel to the at least one adjusting valve in a way that in the closed valve position enables an overflow of the at least one adjusting valve in the direction of the wheel brakes, wherein the hydraulic assembly further includes a changeover device for selectively coupling the wheel brakes to either the hydraulic pressure generated independently of a driver or a hydraulic pressure generated by a driver, wherein the changeover device comprises one 3/2-way valve per brake circuit.
