New Aussie CV joint invention

Just came across this in the newspaper last night and thought some of you guys would be interested in a new CV that they say is the first ever true constant velocity without the high frictional forces of existing ones. It also can handle angles of 15-20 degrees.

• The Thompson Coupling is as essential to our mechanised age as the screw, the crank, the lever and piston
• The Thompson Coupling is the world's first and only Constant Velocity Joint which:
• Has all loads carried by roller bearings
• Has no sliding or skidding surfaces whatsoever
• Can tolerate axial and radial loads without degradation
• Has no torque limitation, constructed to any torque level
• Does not require special lubrication
• Does not require a dust boot
• No wearing components except replaceable bearings and trunnions
• Is suitable for automotive tail or propeller shaft applications
• Is a true Constant Velocity Coupling as distinct from a cv joint
• Is less bulky than a double coupling or double Cardan joint.

Very simple to see the advantages in the demos.

Also states that it is less bulky than a double cardon too.

very cool

but not practical for us. 20 degrees obviously wouldn't cut it for steering joints, and it doesn't look very strong for a given size. maybe they'll improve on those things.

Not for steering shafts but as a replacement for double cardon and CV joints. It is actually smaller for the same torque rating than a double cardon.

I watched the video and thought it was awesome. Very good demonstrations.

I was sold on the invention, but I think it may have been that sauve australian accent that did it.
