Abstract
A transmission system for a vehicle having a belt drive transmission. The belt drive has an adjustable input: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:output ratio of the belt drive allows for a continuously variable transmission system.
Claims12
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:output ratio;
- a second drive having an input and an output, the second drive input driven by the input shaft;
- 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 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:output ratio of the first belt drive.
