Does the CVT have a torque converter?

They don't use a belt, they use a chain.

Scooter. Its a scooter.



I wonder what the rationale is for using TC on a CVT? Seems like an idjit idear.

you need a way to smooth out the changing ratio, absorb shock and also give it the ability to idle in gear. A clutch would make it too harsh.

Makes sense. But then, why not just stick with regular auto transmissions?

Do other cars with CVTs use TCs?

What are you guys talking about? What belt/chain?

Thankfully, the US and Canadian versions don't use the CVT.

I don't see how that's relevant.

Thanks for a direct answer.

This is a simple explanation of it from the service manual:

The continuously variable transaxle (CVT) assembly mainly consists of the following: a pulley and belt unit as a shift mechanism, a planetary gear unit as a forward/reverse switching mechanism, a torque converter, a differential, a CVT fluid warmer to keep the CVT fluid temperature optimal, an oil pump and a valve body unit for hydraulic control.

*1 Pulley and Belt Unit
*2 Planetary Gear Unit
*3 Oil Pump
*4 Torque Converter
*5 Differential
*6 Reduction Drive Gear
*7 Reduction Driven Gear
*8 Differential Drive Pinion
*9 Differential Ring Gear
*10 Differential Pinion

Pulley and Belt Unit (Shift Mechanism)
1. The pulley and belt unit consists of a primary pulley, a secondary pulley and a metal belt applied to the pulleys.
2. In the primary and secondary pulleys integrated with the piston, the pulley groove width can be changed by each chamber's hydraulic control.
3. The metal belt consists of elements and 2 multi-layered rings which hold the elements in a belt-shaped form.

Thanks a lot just what I wanted! Do you have any idea where I can get the full manual for the CVT? I asked in another thread but my replies aren't showing.
