Possible slipper idea??

[BrianG]

OK, don't laugh!

I was looking at my H8 with the "prototype" motor on it using the clutchbell and started to think of an idea about making a compact slipper for buggies using the clutchbell (or something similar). I mean, a Nitro engine uses the clutchbell as a reverse slipper really. You just have the make it so the clutch applies pressure all the time but allows to slip when needed instead. It would be nice to have a compact slipper setup for use with centerdiffs.

After some measurements, I came up with something to start with: Cross-section view of CB slipper

Excusing the crude drawing (using Excel with some Paint Shop Pro touch-ups); basically you have the clutchbell (black) that is coupled to the center shaft by the spring loaded slipper pads (blue) pressed into the inside of the bell via the springs. Since the motor shaft is not long enough to extend to the needed depth, an extender is used. This design allows you to still slide on the bearings (green) and is held with grub screws (purple-ish).

Yeah, it looks dumb and there are some flaws to this design. But I think there might be some merit to it. The biggest problem is to get the shaft extender to fit inside the CB opening and still use bearings. Even using 6mm X 10mm bearings (for the largest inside opening), there is only 1/2 a mm for the "walls" of the extender at one point since the motor shaft is 5mm in diameter. If the CB opening could be bigger, the extender should work.

Anyway, it's just an idea, so be gentle! :dft001:
