Abstract
The present invention relates to an anti-lock hydraulic automotive brake system which includes a pneumatic brake force booster (6) operable in response to the driver and independently therefrom, and a master brake cylinder (8) connected downstream of the brake force booster (6) and having pressure chambers to which several wheel brakes (HR, HL, VR, VL) associated with the vehicle wheels are connected by way of an ABS hydraulic unit (11) with a pump (7). Means (1, 2, 3, 4, 5) are provided which sense the actution of the brake force booster (6), control the pump (7) and constitute a hydraulic connection between the master brake cylinder (8) and the suction side of the pump (7).
Claims8
An anti-lock hydraulic automotive brake system comprising:
- a pneumatic brake force booster operable in response to a driver;
- a master brake cylinder connected to the brake force booster and having pressure chambers to which several wheel brakes associated with vehicle wheels are connected by way of a brake line and an ABS hydraulic unit including a pump with a suction side and a pressure side;
- a pressure sensor that senses the pressure developed by the master brake cylinder;
- a multi-way valve constituting a hydraulic connection between the master brake cylinder and the suction side of the pump;
- a diaphragm connected to said hydraulic connection, interposed between the multi-way valve and the suction side of the pump;
- and
- a pressure sensor positioned on the pressure side of the pump.
