Brake system for rear wheels of motor vehicle - feeds brake pressure to front and rear wheel cylinders equalised upon faulty functioning of antilocking protection adjustment

摘要

The hydraulic brake system has a brake pedal (26) for regulating a brake pressure, an antilocking protection device for regulating a brake pressure in order to prevent the rear wheels becoming locked, a judgement device (128) which determines a fault function of the protection regulating device, a front brake device (100,102) for braking the front wheels (96,98), a rear brake device (108,106) for braking the rear wheels (104,106), and a device (10) developing a high pressure which produces a high pressure in relation to an operation of the brake pedal (26). A low pressure developing device (12) produces a low pressure in relation to the operation of the brake pedal, and feed equipment (90,92,94) feeds the high pressure to the rear brake device (106, 108) and the low pressure to the front brake device (100,102). Change-over equipment equalises the pressures fed to the rear and front wheels when the judgement device (128) determines a fault function. USE/ADVANTAGE - To increase braking force on rear wheels, thus prolonging useful life of brake linings of front wheels.
