<p>A vehicle drive transmission system includes a continuously variable speed-control unit of the expansible pulley type whose output shaft is drivingly connected via a reduction gear unit to a differential gear. The differential gear has two coaxial output shafts which are connected to the half shafts of the vehicle's driving wheels. Both the reduction gear unit and the differential gear are epicyclic in form and are arranged coaxial with the output shaft of the speed control unit. To accommodate this compact arrangement, both the output shaft of the speed control unit and the input shaft of the reduction gear unit are made hollow so that one of the output shafts of the differential gear can extend therethrough.</p> |
