AUTOMOTIVE BRAKE DRIVE Russian patent published in 2013 - IPC B60T8/60 B60T13/68 

FIELD: transport.

SUBSTANCE: invention relates to automotive industry, particularly, to brake systems and can be used to up the braking efficiency. Brake drive consists of three independent circuits, i.e. one circuit of front wheels and two circuits of rear wheels. Proposed drive comprises compressor, air cylinders, pressure gage, brake chamber, brake pressure control valve and booster valves. Circuits of rear wheels comprises power accumulators (air cylinders) and safety single reverse-flow valves with compressed air control to sustain required level between air cylinders. Said safety single reverse-flow valves are arranged upstream of air cylinders of rear wheels. Power flows are controlled by three-way brake control valve.

EFFECT: higher trailing weight at breaking, minimum consumption of compressed air in braking, better stability at poor-grip roads.
