High articulation driveshafts
High articulation driveshafts
(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

The first is 7-8,000 RPM. Is there an axle with gear reduction or does the car simply go 120 MPH sideways?
The second is 90*. A wheeled vehicle can literally turn in place with less than 90* at the wheels. Is there another axle that can share the turning chores or does the car actually go sideways?

I appreciate the driveline calcs for vehicle speed and so on but don't fear - you're all right in your points but nonetheless I want to be able to rotate the output of the driveshaft through 90 degrees without excessive losses / efficiency degradation.
Does anyone know a way?

Driveshaft speed does not make sense.
Drive train layout does not make sense.
Secrecy level set too high.
