Michael, I did buy a pair of Hooke joints, but there was so much backlash in them that it wasn't worth installing them. Hooke joints have poor angular velocity variations. Its interesting that the MINI used to have 1 x Hooke joint and 1 x CV joint - I wonder how that worked out !

I did have 1 x beam joint of a far superior quality, but I needed 2! The ones I have are several magnitudes stiffer !

This looks like the Rolls Royce Beam couplings

It was a (very stiff) rubber/metal bonded kind of U/J that was located next to the gearbox and because of that, it didn't need to flex very far with suspension & steering movement, when compared to the C/V joint, which was mounted on the streered wheel hub.

It mentions torsional variations but then refers to steady state. If its steady state then where do the dynamic loadings come from?

Just curious

.

I think they are admitting that the spiral will wind-up [or unwind] with dynamic changes … and their ‘steady state’ reference is to the shaft running at constant speed.
