Possible slipper idea??

[jhautz]

Just thought of another thing to worry about with any of these slipper designs. The heat generated by a slipper would be being transfered to the motor shaft and into the motor. I'm not sure if its enough to worry about, but the motors generate enough heat already. We don't need to be adding more.

True, but only if/when it slips. The idea is to just provide drivetrain protection, so it shouldn't be slipping that often. It is a thought though.

I really like this idea as it would eliminate our troubles with pinions and gearing since we could use standard clutch bells. My only concern from heat would be fade from limited contact area. With a center diff you don't really need much slipping action, so that wouldn't be an issue, but on the monster trucks where some slipping would be beneficial aside from just protection I would worry about heat generation.

This thread talks about the hardened steel pinions and Mike's view on them. I'm thinking that a slipper would go a long way to make those pinions wear better since there would be some give with some form of slipper.

I'm not sure about the potential heat issue. Nitros use the clutch a lot harder since it slips most at low rpm. The heat is caused by the rubbing surfaces when there is slippage. As long as the hub and CB spin at the same rate, there is no slipping, therefore no heat.

I wonder what Mike's take is on all this? I'd be curious as to what he thinks.

Nitros also have much more contact area in their clutch than the above drawing. I admit I didn't look at yours close enough. As long as contact area was equal to or greater than a nitro clutch (as yours shows) I would not be concerned about heat.

I still don't think any effective drive gear solutions exist as abundantly (and therefore inexpensively) as clutch bells.

Don't forget; my drawings are crude cut-aways. I was thinking of having four seperate fairly large pads covering the majority of the CB depth, which should approximate the amount of suface area of clutch shoes.

Yeah, there really isn't anything for buggy conversions yet, hence this thread.
