VEHICLE ANTILOCKING BRAKE SYSTEM Russian patent published in 2005 - IPC

FIELD: automotive industry.

SUBSTANCE: proposed antilocking brake system of automobile includes brake mechanism of front and rear wheels, hydraulic set with channels to control brake mechanisms of front and rear wheels, two-section brake master cylinder, two-circuit pressure regulator containing housing, primary and secondary circuits with valves, sealing unit separating said circuits, piston included into primary circuit and spring-loaded relative to housing. Input of secondary circuit of two-circuit pressure regulator is connected to one of spaces of two-section brake master cylinder. Input of control channel of rear wheel brake mechanisms of hydraulic set is connected to second space of two-section brake master cylinder. Sealing unit of two-circuit pressure regulator contains spacer bushing and pusher passing through bushing. Valve locking elements rest on opposite end faces of pusher. Input of primary circuit of two-circuit pressure regulator is connected with output of control channel of rear wheel brake mechanisms of hydraulic set, and outputs of primary and secondary circuits of two-circuit pressure regulator are connected with brake mechanisms of rear wheels.

EFFECT: simplified design of system, improved reliability.
