Power train for motor vehicle, has gearbox downstream to speed change gearbox and with transmission ratio, which is increased by reciprocating value of transmission ratio of front-mounted gearbox for adjustment of output speed and torque

摘要

The train has a non-adjustable single-step front-mounted gearbox (9) directly connected upstream to a speed change gearbox (6) for decreasing an input torque. The gearbox (9) is attached to a lubricating oil supply of the gearbox (6). A gearbox, downstream to the gearbox (6), exhibits a transmission ratio that is increased by the reciprocating value of transmission ratio of the gearbox (9) for adjustment of the output speed and torque.
