摘要 |
The present invention relates to a hydraulically actuated brake system for vehicles, comprising a hydraulic pump (18), a high pressure hydraulic accumulator (24) for a powershifted brake system (10) and a conventional master brake cylinder (10) used to indicate the prescribed braking force value. The invention suggests that a suction part of the hydraulic pump (18) be connected to a low pressure hydraulic accumulator (20) into which the brake fluid flows from the wheel brake cylinders (16) when the wheel brake pressure goes down. The advantage of the inventive system is that it makes useless the connections from the hydraulic pump (18) to a holding tank (12) of the master brake cylinder (10), which are likely, in case of sealing defect, to bring about a malfunction of both the powershifted brake system and the auxiliary manually actuated brake system.
