ROAD VEHICLE SLIPPING WHEEL AUTOMATIC BRAKING DEVICE Russian patent published in 2001 - IPC

FIELD: transport engineering. SUBSTANCE: pneumohydraulic device and distributing mechanism are additionally installed in slipping wheel automatic braking drive. Pneumohydraulic device has two cylinders with pistons mounted on common rod. Hydraulic cylinder space is hydraulically coupled through throttle with double-side hydraulic cylinder, and space of pneumatic cylinder is pneumatically coupled with distributing mechanism. Spool-type distributing is pneumatically coupled with air receiver. Winding of spool electromagnet are electrically coupled with storage battery through cut-in relay, cut-out and normally open switch. Invention provides increase of road vehicle cross-country capacity. EFFECT: improved of braking considerable consumption of energy from storage battery, simplified design of device and enhanced reliability. 1 dwg
