ABSTRACT:
A torque tube propshaft assembly having an outer tube free to float with movements of an inner shaft (propshaft) by being free of rigid anchorage at each end. A plurality of shaft bearings interface the outer tube with the inner shaft, wherein the outer tube is generally co-extensive with the inner shaft. An anti-rotation mechanism prevents rotation of the outer tube with respect to the frame of the motor vehicle. An axial slip mechanism is integrated with at least one end of the inner shaft. A non-welded construction of the power carrying components is provided. The outer tube provides bending support so the inner shaft does not become dynamically unstable at any rotation speed including its critical speed.
