TWO-SPEED DRIVE OF POWER TAKE-OFF SHAFTS OF TRANSPORT VEHICLE Russian patent published in 1994 - IPC

FIELD: general-purpose row crop tractors. SUBSTANCE: drive comprises engine, transmission for transmitting torque to driving wheels via clutch, gearbox and rear axle. Using equipment receives energy through synchronous or independent power take-off shaft, gear wheels of reduction units and gearbox, and couplings. The links of kinematic chain connect gearbox main shaft by flexible linkage through gearshift coupling with extension of lower rear power take-off shaft and, via gearbox countershaft, sliding gear and gearshift coupling, with extension of front power take-off shaft. Drive of front power take-off shaft includes coupling for selective meshing by gears with countershaft or with engine. EFFECT: improved design. 1 dwg
