WHEEL-MOUNTED POWER SHOVEL Russian patent published in 2002 - IPC

Abstract RU 2184193 C2

FIELD: mechanical engineering; earth moving machines on wheeled running gear with hydraulic drive. SUBSTANCE: proposed wheel-mounting power shovel has power plant, hydraulic system consisting of power pumps, distributor, hydraulic motors, central manifold, servocontrol hydraulic lines with columns, travel motion mechanism with truck, gearbox and gearshift mechanism with servo drive. Gearbox gearshift mechanism is provided with synchronizer. Gearshift mechanism has channels connecting gearbox servocontrol hydraulic line with distributor servocontrol hydraulic line. Flows of servocontrol hydraulic lines from servocontrol column and from gearbox control mechanism to hydraulic system distributor are connected through OR valve. EFFECT: enlarged range of traction characteristics by provision of possibility to change over gears on the go, facilitated control. 4 dwg
