Multi-range, belt-type, continuously variable transmission |
摘要 |
In a multi-range, continuously variable transmission, input engine power is split between a belt-type, continuously variable transmission unit and a system of interconnected planetary gears. This gear system then combines the split power received from the engine and the transmission unit output to produce a transmission output for propelling a vehicle in multiple forward ranges and one reverse range, each range of continuously variable speed produced by stroking the transmission unit. Synchronous shifting between ranges is achieved by selectively clutching or braking elements of the planetary gear sets at appropriate stroke settings of the transmission unit, such that the vehicle may be smoothly accelerated from rest to maximum speed.
