Abstract
A transmission system for a vehicle having a belt drive transmission. The belt drive has an adjustable input and output ratio, where the output of the belt drive is provided as a first input to a differential coupling. A further rotating connection is provided as a second input to the differential coupling, so that the output of the differential coupling is arranged as the output of the transmission system. Accordingly, the transmission output is based on the aggregate sum of the rotation of the first and second inputs to the differential coupling, wherein adjustment of the input and output ratio of the belt drive allows for a continuously variable transmission system.
Claims8
A belt drive transmission system comprising:
- an input shaft to be driven by a prime mover of a vehicle;
- a first belt drive having an input and an output, the first belt drive driven in a first direction by the input shaft, the first belt drive having an adjustable input and output ratio;
- a second belt drive having an input and an output, the second belt drive input driven by the input shaft in a second direction opposite to the first direction, the second belt drive having an adjustable input and output ratio;
- and
- a differential coupling having an output connected to a driven axle of the vehicle, the differential coupling driven by the outputs of the first belt drive and the second belt drive to provide an aggregate drive at the output of the differential coupling,
- wherein the output of the differential coupling can be varied by adjusting the input and output ratio of the first and second belt drives, the output of the differential coupling being driven in a forward or reverse direction based on the output speeds of the first and second belt drives;
- and wherein the transmission system further comprises a speed select mechanism having an input and an output, the output of the belt drive transmission provided as input to the speed select mechanism, and the output of the speed select mechanism connected to the driven axle, and wherein the speed select mechanism comprises a plurality of selectable geared connections arranged to provide a variety of speed ranges in the transmission path between the prime mover and the driven axle.
