COMPACT INLINE LONGITUDINAL CVT

摘要

A series inline continuously variable transmission (SICVT) in which two series coupled continuously variable transmissions are in an inline configuration is provided to be used in rear-wheel drive vehicles. Two sets of pulleys are connected in series to square the reduction and bring the input and output shafts inline. The input and output pulleys are configured for actuation by hydraulic pistons for shifting, while the idler pulley set may be implemented without a need for actuation. Displacement of the actuated pulleys results in the square of the original ratio change. The SICVT is compact and efficient, and can be used in all types and sizes of vehicles including gasoline and diesel powered vehicles and electric, fuel cell electric, and all types of hybrid electric vehicles. Additional CVT stages can be provided for further reduction in size.
