Half-Shaft Design
Half-Shaft Design
(OP)
I have to design half-shafts for a special FWD application, and I'm not familiar with the application. So I have a couple of questions:
1. During bounce, the wheel-to-transmission distance will change due to suspension geometry. The inboard CV joint will be fixed at the transmission. Do I allow the splined (outboard) shaft of the CV joint to slide inside the spindle to account for the change in distance?
2. Is it critical to locate the outboard (steering) CV joint on the steering axis? If the outboard end slides (laterally) then the location of the CV joint center will also vary in relation to the steering axis.
Anyone know of a paper on the applications criteria of half-shafts for FWD vehicles?

(2), no, but you'll find that you only have limited plunge in the plunge joint so you can't sacrifice too much by moving the ball away from the steering axis.
