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.

A motor vehicle transmission for producing a stepless range of torque ratios between an input member and an output member comprising: means connected to the input member for varying its torque ratio by steplessly changing the radial distance from the axes of the input member and its output member at which an endless, flexible belt driveably engages these members; a hydrodynamic torque converter connected to the output of the torque ratio producing means, adapted to multiply the torque output of the torque ratio producing means over at least a portion of its range; and a gearset connected to the output of the torque converter adapted to selectively produce forward drive or reverse drive at a constant torque multiplication.
