Angled Driveshafts for traction

[THR]

It was suggest to me that the reason that driveshafts are angled is to improve traction. is this true and can anyone explain y? and how?

by angled driveshafts i mean... if u look top down on the rear gearbox of a single seater, the gearbox appears forward of the wheel. maybe angling the driveshaft 10deg.

I don't really get by what you meant by 'angled driveshaft' but if i undesrtands your question correctly....

The angle between the yoke and pinion must be of the same degrees. Because yoke is turned by the transmission while the pinion is being turned because of the differentials of the moving car.

This is as to avoid vibrations or shaking effects. The yoke and pinion can be angled at whatever degrees you want as long as it's unison.

I don't see any sense of traction advantage...maybe others have different opinions

na not quite wot i meant.
between the wheel hub and the gearbox
the actual driveshaft, not the gearbox internals.

differentials has got to do with traction not driveshafts gtr69

oppsss....THR not gtr69..sorry

Hi driveshafts are normally only angled to put the engine/gearbox unit more forward in the chassis (more central between the axle center lines ) to aid front / rear weight distribution and give less rear overhang.
hope this helps

thats wot i thought. but on this particular car, they could have put them where ever they wanted to, and chose to put them there!

i guess they were wrong then if none of u can think of a reason for it! i couldnt

[Hitech]

The main reason driveshafts are run at an angle and not straight is to work the balls in the joints over a larger load path as they rotate. Straight driveshfts were found to give premature joint wear on road cars, and I guess this must have been continued as good practice in race car design. Angled driveshafts do consume more power though so angles are usually kept within five degrees. I've tried many variations of angles over the years on my hillclimb cars and have not found any effect on traction, which is the usual old wives tale about why drive shafts must sweep forward when vieved from above.

my view too Phil.
this was on the new DJ carbon car that i was told about the driveshafts, they couldnt explain it either but said it was theoreticaly correct to angle them.
