All UTV's How the clutch works!!

here is some good reading on how our UTV clutches works.

this shows a dry clutch setup on a snomobile but the principles are the same.

this is a good example of how the RZR and Teryx work, the rhino with rollers and Cam plate would act similar in reguards to roller weight, but the cam plate is of a fixed angle and not as tuneable as the profile weights in the dry clutch setups, like Bronco or PDM.

Re: how does the cltuch work

great post Rog!!! Thanks for hooking us up with some great info!! This is a Sticky Thread!!
 
Rog - I was on Gates site two days go and found that page! Very good stuff...but Gates pissed me off as I have one of their sonic tension meters, but the CVT belts can't be used with it!!! It would make setting the belt so easy...guess I need to dig out my fish scale!:D
 
The big difference in the secondary between what I just read and the Rhino is the rhino is not full helix, therefore doesnt have near the torque sensing backshift ability that all others do. Its only helix for the first part of the movement.

yes it is a rotational style with pins in a groove in radiused slots, the effect is similar and torque sensing, but not to the degree that a snomobile helix has.

but for the basic SxS owner it provides soem good info on what is happening, don't ya think Court??

Bob, I had this site marked last year when searching for belt replacements, I used to use gates belts in all my snomobiles and had good luck, and was seeing if I could find one for a rhino.

Very good description of how the CVT works. I think a full helix type secondary would work a lot better for us, just havent had time to prove it. The pin and slot system works fine, just not sure why the slots start angled and then go straight, thus only torque sensing for the first part of the secondarys travel. Probably to 20mph or so. .
 
This post was made in 2009 so it looks like Gates may have done away with the og video... too bad..
