Infinitely variable belt-drive transmission

摘要

A continuously variable belt driven pulley system drives a torque converter followed by a planetary reversing speed reduction gearset another speed reduction unit and the differential, which distributes power to the drive wheels of the vehicle. The drive system of a motor vehicle according to a second aspect of the invention includes a continuously variable flexible belt-pulley system driving a reversing bevel or planetary gear set and a tandem fluid coupling, which functions as a limited slip differential and distributes power to the drivewheels of the vehicle through two speed reduction gearsets driven from two output shafts of the fluid coupling.
