dont have a prop on my trike, just a u/j,
whilst it doesnt pose a problem, i was thinking of swapping it out
in favour of a rubber buffer style thingy,
i have seen these on some of the newer rear wheel drive propshafts on cars,
anyone had experiance with these? or had any ideas on which to try and use,?

Think most BMW cars now have them, bit like the old Hillman Imp rubber doughnut, Lotus had them on the elans and I think Triumph used them on GT6 and spitfire variants. Do recall many moons back some bad press and many tried to convert to a constant velocity type joint, but things have moved forward in rubber gear now.

I made up the carriers for one once ( for a chèvre tote rally car), it took quite a bit of machining. If you can get one to bolt on, laughing, otherwise it could be expensive.

I'm thinking of doing the same digger06 as i to don't have a prop and the way i see is my engine is fixed as is the axle so using a doughnut as a cushdrive would work the same as on a motor cycle, the one i'm using is from a BMW.

is that capable of taking a bit of movement/misalignment, or is it just for shock absorption?

Would have thought these would be better than a single UJ on a Reliant where there is no sliding coupling. It would allow for the linear expansion you get as the gearbox and diff heat up.

Modern marine/boat drive shaft systems use CV joints now, we have one fabricated in this style for our inboard engined speed boat. If you use this type of shaft, the ends it's attached to (gearbox and rear axle) have to be solidly mounted at either end i.e. normal style gearbox with a bolt on flange and something like a Sierra rear axle. Basicly you'd be using front wheel drive shaft technology http://www.aquadriveusa.com/system/system.htm |
