Torque management system from DANA

I found this in the 2-22-01 edition of Machine Design. Thought it looked interesting... It won't let me attach the entire file, so I'm going to attempt to crop it and put it inside my post.. [img]/wwwthreads_images/icons/smile.gif[/img]Bret

Re: Torque management system from DANA

Okay, here's the picture:

Torque transfer systems -- those that sense wheel slip and reroute torque to the wheels getting traction -- can be expensive and complex. A new type of torque-management system, dubbed TXT by its developers at Spicer Light Vehicle Axle, a division of Dana Corp., Fort Wayne, Ind., can be installed on front or rear axles and works without driver intervention. It smoothly transfers torque from a spinning wheel to the wheel getting traction.

The system is made of two concentric housings, with a ring gear bolted to the external housing. A standard (or open) differential inside the external housing is free to rotate. A hydraulically actuated clutch pack connects the internal and external housings. A speed difference between the left and right axles activates the clutch pack.

The system, totally contained in the axle differential, controls the amount of torque transferred. It is a much lighter and more efficient package compared to other torque-transfer schemes. TXT also eliminates torque coupling devices which are commonly used in 434 vehicle. These devices generate noise and unwanted vibrations. TXT, which is compatible with ABS, is currently a hydromechanical system. But it will soon be available with electronic control over the hydraulics.
