VEHICLE ENERGY RECUPERATOR Russian patent published in 2002 - IPC

FIELD: transport engineering. SUBSTANCE: invention relates to means of recuperation of energy of braking and suspension vibrating by means of pneumohydraulic accumulator. According to invention, suspension cylinder 11 is secured on housing of axle 10 of wheel 9. Cylinder 11 is divided into two spaces 16, 17 by piston 14 with rod 15 connected with frame 13. Spaces 16, 17 are placed in communication with hydraulic tank 1 and with pneumohydraulic accumulator 3 by hydraulic main lines. Train couples driving wheels 9 with hydraulic motor 4. Acceleration rod 39 is coupled with hydraulic valve 31 which provides delivery of liquid from energy accumulator 3 to hydraulic motor 4. Braking rod 40 is coupled with hydraulic valve 32 which provides delivery of liquid by hydraulic motor 4 into accumulator 3. Hydraulic valve 31 is made in form of piston with rod on which piston-like hydraulic valve 32 is installed for movement, and spring 33 is arranged between hydraulic valves 31, 32. hydraulic valves 31, 32 are connected by corresponding main lines with control unit 45 of clutch 5 connecting hydraulic motor 4 to driving wheels 9. EFFECT: improved efficiency of energy recuperation. 1 dwg
