Hydraulic Braking System Having a Temporary Store

摘要

The invention relates to a hydraulic braking system for a land vehicle, having at least one wheel brake; a master brake cylinder, which is designed to displace hydraulic fluid into the at least one wheel brake upon actuation of the braking system by the driver; a pump, which is designed to displace hydraulic fluid into the at least one wheel brake; a plurality of valve arrangements; a control unit, which is designed to actuate the pump and the plurality of valve arrangements; and a temporary store, which is connected hydraulically to the at least one wheel brake and to an input of the pump. The temporary store comprises a restoring element and is designed to accommodate a hydraulic fluid reserve volume during a rest state of the braking system, and to make the accommodated hydraulic fluid reserve volume available to the pump for displacement into the at least one wheel brake during an actuation state.

1. Hydraulic brake system for a land vehicle, comprising
at least one wheel brake, which is assigned to a wheel of the land vehicle; a master cylinder, which is hydraulically connected to the at least one wheel brake, wherein the master cylinder is adapted to displace hydraulic fluid into the at least one wheel brake when the brake system is actuated by the driver; a pump, the output of which is hydraulically connected to the at least one wheel brake, and the pump is adapted to displace hydraulic fluid into the at least one wheel brake; a plurality of valve arrangements;characterised by
a control unit which is adapted to drive the pump and the plurality of valve arrangements and, during the actuating state, to drive at least one first valve arrangement, arranged between the at least one wheel brake and the master cylinder, such that the first valve arrangement throttles a volume displacement from the master cylinder to the at least one wheel brake; and an accumulator, which is hydraulically connected to the at least one wheel brake and to an input of the pump, wherein the accumulator includes a return element and is adapted to accommodate a hydraulic fluid reserve volume during a non-operating state of the brake system, and provide the accommodated hydraulic fluid reserve volume to the pump for displacing it to the at least one wheel brake during an operating state of the brake system.
