Ever see these types of CV's ?
]http://cvcoupling.com/index.php?option=com_content&task=view&id=36&Itemi d=58"]Thompson Couplings Ltd [/URL]
The Thompson Coupling is certainly amongst the most important inventions since the advent of the internal combustion engine. It is the world's first and only, practical, constant velocity joint to have no load bearing sliding surfaces.
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
In mass production each and every component of the Thompson Coupling can be produced by forging and/or casting with the only further requirement being to drill and machine the bearing journals, holes and circlip grooves. No dedicated machinery is required and there is no complex machining at all. Bearings for most applications are stock and assembly is very simple. For one-off project applications, manufacture is simple and within the capability of any machine shop. No specialist machinery is required as is the case with Rzeppa type joints. A Thompson Coupling can be disassembled with a pair of circlip pliers and the bearings replaced with a minimum of expertise and downtime. The Thompson Coupling is very compact and may be over-engineered to increase reliability without adding substantially to bulk and weight. It is obvious that use of the Thompson Coupling in lieu of Cardan Joints (traditional unis) will eliminate a large source of vibration in many machines and automotive applications.

I just found this, anyone seen this before?

Re: Ever see these types of CV's ?
The motor current over time graph is bullshit.
I don't care what the LIT-er-ah-CHOOR says, but any moving part that exists in an automotive environment without so much as a dust boot, much less sealed and lubricated, is designed to fail. If it's designed to take sealled bearing assemblies i should say so, bu it doen't.
It might still be a great design, but the concept has been presented to us by marketing execs not engineers.
