Hydraulic multi-circuit brake system including a traction and anti-skid control device for motor vehicles

摘要

A multi-circuit brake system having an anti-skid and traction control device for non-delayed, driver-activated braking. The multi- circuit brake system has a self-aspirating pump, which in case of traction control operation aspirates pressure medium from a pressure medium reservoir via an aspirating line and a main brake cylinder. A valve assembly in the brake line of the non-powered vehicle wheel is switched to maintain pressure in this case. A valve assembly, open in case of traction control operation, is located in the aspirating line. An auxiliary brake line with a pressure-controllable valve assembly originates at the aspirating line on the side towards the pump, when the valve assembly in the aspirating line is open, brake pressure generated by the driver by activating the main brake cylinder can be supplied to the wheel brake of the non-powered vehicle wheel. The invention is particularly suited for motor vehicles.
