I also didnt know about the Prius planetary CVT until John mentioned that it was not belt driven like most others and your link showed it in detail. Great site if I do say so myself.___Jchan2, I havent heard back from the 03 Prius E-Bay purchaser so far?
Sport Mode, and paddle shifters. The key to the Dynamic Shift CVT’s distinct performance feel is a gearset used as a “first” gear for start-off acceleration, before seamlessly
Regarding gearbox in Prius, the planetary gear set is just that. It may have only a single ratio, but it serves the purpose that a typical CVT would (other than that a typical CVT would continuously vary the gear ratio to maintain engine speed while car accelerates). If...

The traditional Toyota hybrid CVT transaxle also got a rework. The electric propulsion motor, called MG2, is smaller and lighter than before. To trim friction, the planetary gearset between MG2 and the final drive has been replaced by helical gears. A second electric motor/generator, called MG...
it exceeded the fuel efficiency of the previous generation. The latest version of its Hybrid Synergy Drive combines the output of a 1.8-liter 4-cylinder gasoline engine and two motor/generators through an electronically controlled planetary-type continuously variable transmission (CVT). Sh...
The first planetary gear set 24 has rotary elements consisting of: a first sun gear S1, a first planetary gear. P1; a first carrier CA1 supporting the first planetary gear P1 such that the first planetary gear P1 is rotatable about its axis and about the axis of the first sun gear S1...
Preferably, the planetary gear set is of a single-pinion type. In this case, the axial dimension of the differential mechanism can be reduced, and the differential mechanism is simply constituted by one planetary gear set. Preferably, the overall speed ratio of the vehicular drive system is def...
More preferably, the differential mechanism includes a planetary gear set comprised of a first element connected to the engine, a second element connected to the first electric motor, and a third element connected to the power transmitting member. The first element includes a carrier of the planeta...
