Comet - CVT

[vmrod]

This is a tpye of torque converter found on a snow mobile.

Rather than had a 1 or 2-speed, I'm looking into this possibility.

There are 3 hurdles to overcome to use this device.

1. Drive shaft and Jackshaft should be minimum 8.8" apart.
(Can redesign RA to move Jackshaft rearward 1"+. Minimal impact. Must recut aluminum plates as these were cutout just last night! )

2. Air Spring and shock absorber mounts need to be relocated slightly to adjust for the movement in the Jackshaft.
(No biggie here. Just paid attention to how much things moved.)

3. The drive pulley on the snow mobile CVT has a 30mm / 1:10 tapered bore. This means that it will NOT fit on the shaft of a Warp 9.
(Talked to a nice fellow at Dutchman axles. If I purchase a TransWarp 9, he will either reshape the motor shaft for me, or reshape the pulley bore to match the TransWarp shaft.)

Anyway, sounds like a pretty good way to go!

Well, since no one else is apparently using this, I decided to forego it as well.

I had to make some small changes to my RA to accomodate the CVT. (in design only) However, since the changes are minimal impact, I'll keep them. If ever I feel 'sausy', I may decide to go ahead and pioneer a CVT. I'll have the setup ready to go!

Back to the tranny!

I also was thinking about using a CVT for a snowmobile. I was picturing it in a UrbaTrike for running around town. Maybe using a chain drive motorcycle engine and a jackshaft for the CVT. Just thinking....Scooter

Once I shrug off this jet-lag, maybe I can dig-up the exact part numbers that the engineers at Comet recommended for an electric motor.

Keep in mind that a snowmobile engine develops power at high RPMs, while an EV develops power instantly. Thus the clutch mechanism has less or no springs in it.
