DEVICE FOR RECUPERATION OF KINETIC ENERGY OF MOVING VEHICLE BRAKING Russian patent published in 2009 - IPC B60T13/138 B60K6/12 B60L7/16 

FIELD: engineering industry.

SUBSTANCE: present invention is concerned with vehicle engineering industry and namely with wheel and tracked vehicle brake systems. Device consists of main brake hydraulic cylinder, pipe lines, brake fluid and return valve. On gear box primary shaft there strictly fixed is hydraulic engine rotor, and on gear box secondary shaft there strictly fixed is drive gear installed with the possibility of transmitting rotation from drive wheels to differential device. Device also includes high and low capacity pumps, hydraulic chamber with diaphragm that communicates with piston of hydraulic chamber slide valve. When piston closes slide valve of hydraulic brake pedal and slide valve of hydraulic chamber in discharge side of low capacity pump, discharge side of high capacity pump is connected with hydraulic accumulator of operating fluid via back-pressure valve. Hydraulic brake pedal is connected with finger that can freely move to support point in rod through hole of elliptical form. The rod actuates the piston of slide valve of hydraulic brake pedal in reciprocating motion. Throttle control pedal is connected with finger that can freely move to support point in rod through hole of elliptical form. The rod actuates the piston of control slide valve providing the connection of one of hydraulic engine rotor gears with operating fluid in hydraulic accumulator through hydrovalve if gear box is switched on. Pressure switch is actuated if there is specified operating fluid pressure in hydraulic accumulator.

EFFECT: fuel economy is increased and vehicle parts wear during operation is decreased.
