Patent DE-3903532-A1 (DE)
Title: Hydraulic motor-vehicle brake system with an anti-lock control device
Inventor: GABRISCH ROMAN DIPL ING
IPC: B60T13/16
Filed: 1989-02-07
Abstract: In a known hydraulic motor-vehicle brake system with an anti-lock control device, a controllable hydraulic pump connected to the wheel-brake cylinders is provided, this pump taking over the function of brake boosting when the anti-lock control system is inactive and assuming the function of a brake-pressure modulator when the anti-lock control system is active. For this purpose, its output pressure is, in the first case, controlled by the output pressure of the master brake cylinder and, in the second case, by a control signal output by the anti-lock control device. In the new hydraulic motor-vehicle brake system, the intention is that a hydraulic pump should likewise assume both the function of brake boosting and the function of pressure modulation but that the outlay for this purpose, particularly the outlay for control, should be comparatively low. The hydraulic pump, which is preferably designed as a gear pump whose direction of delivery can be reversed and can be switched on automatically when the service brake is operated, is in each case inserted in the brake line leading from the master brake cylinder to the wheel-brake cylinders. Connected in parallel with it is a proportional-pressure control valve, the low-pressure port of which is connected to the hydraulic pump on the master-brake-cylinder side and the higher-pressure port of which is connected to the hydraulic pump on the wheel-brake-cylinder side. <IMAGE>
