Constant velocity coupling >90deg articulation
Constant velocity coupling >90deg articulation
(OP)
Hi, I'm trying to find out if anyone has ever found a drive coupling able to handle high levels of power (>100kW) at speeds up to 7-8000rpm while able to articulate from 0 degrees up to 90 degrees.
I thought about a bevel coupling with input and outputs picking up off a joint bevel gear but worry this is heavy and unwieldy.
Is hydraulics or electric drive my only option?
An application would be for a car able to steer the wheels 90 degrees out of axis from the driveshaft.
Alternatively arrangements with the nominal shaft angle at +45degrees to the wheel in normal operation and articulating to -45degrees in the other mode would be considered.
Thanks,
John

RE: Constant velocity coupling >90deg articulation
The other place I’ve seen this sort of thing was on a Mack 4WD army truck. The set up allowed for the diffs to be mounted close to the top of the chassis rails allowing for greater ground clearance.
Hope this gives you some ideas.
