drive shaft angle
dilley - 10/7/10 at 10:36 PM

Hi Guys,

I am trying to do a mock up of a bike engine and a chain drive diff in my buggy and its bloody tight!!!

Is there any reason why I cannot move the diff back and run the drive shafts not at 90 degrees to the wheels??

drive shafts move up and down so why not foward or backward fixed/mounted???

hope tis makes sense!!

If it's only a few degrees it is actually beneficial as it spreads the wear a bit more
rather than a constant load at one part of the CV.

as long as you are still in the working envelope of the cv you will be ok. Dont exceed the angles other wise they blow up

Should be fine - just don't go for huge angles! I've been running my driveshafts at about 8-10 degrees now for a few hundred miles without any problems.

Mine are at ~5 degrees with no problems in 3 years.

I had some teething problems with the CV boots exploding due to the angles caused by strapping the car down on the rollers - I think the grease was thrown to one side and the centrifugal force made it burst through the boots .....twice! All this happened at a roller speed of 150mph

This was cured by using a race quality CV boot which doesn't flop about like the cheapies. You can see the difference in this pic. Rescued attachment Driveshaft Boots.jpg

At the risk of a hijack, mine have 11 degress is that too much? Or will it just wear quicker.

Obviously fwd car operate huge angles at the outer cv joint, and under power.

Thanks
