Title: prop rubber buffer Post by: digger06 on August 18, 2014, 01:28:49 PM 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,? Title: Re: prop rubber buffer Post by: the coppersmith on August 18, 2014, 03:42:54 PM 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.

Title: Re: prop rubber buffer Post by: saex69 on August 19, 2014, 11:57:47 PM 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.
Title: Re: prop rubber buffer Post by: digger06 on August 23, 2014, 08:39:47 AM you got any pics of this?
Title: Re: prop rubber buffer Post by: saex69 on August 23, 2014, 03:53:31 PM Here ya go you will only need to use 4 holes or you could use all of them.
Title: Re: prop rubber buffer Post by: minimutly on August 24, 2014, 11:19:04 AM 3 each surely?

Title: Re: prop rubber buffer Post by: digger06 on August 24, 2014, 01:32:42 PM is that capable of taking a bit of movement/misalignment, or is it just for shock absorption?
Title: Re: prop rubber buffer Post by: hunter on August 24, 2014, 01:43:18 PM It's basicaly a shock absorber,
But you can trasmit a couple of hundred horspower through these things. This one's from a BMW Z4 i think.

It would allow for the linear expansion you get as the gearbox and diff heat up.
Title: Re: prop rubber buffer Post by: digger06 on August 25, 2014, 07:23:07 AM what about a cv joint?as above, it was the heat/expansion i was thinking about,
Title: Re: prop rubber buffer Post by: phunkie hiboy on August 25, 2014, 08:57:43 AM what about a cv joint?as above, it was the heat/expansion i was thinking about, 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 Title: Re: prop rubber buffer Post by: the coppersmith on August 25, 2014, 09:04:44 AM Plus they are a bit bulky
Title: Re: prop rubber buffer Post by: digger06 on August 26, 2014, 04:25:59 AM I have gone for a rubber like the one above,
I will throw some piccys on when I start it, edit, thread started |
