ABSTRACT:
Fitting yokes are coupled each by a universal joint of the trunnion type to the opposite ends of a shaft assembly biased for axial extension. Each of the fitting yokes has a sleeve inserted in a center bored portion of the universal joint with a clearance formed therebetween to permit relative angular displacement between the axis of the shaft assembly and the axis of the fitting yoke. The drive shaft therefore has a greatly reduced length in its entirety. The shaft assembly includes a splined portion adapted to permit collapsing and extension of the assembly and circumferentially covered with a sleeve-shaped cover. The cover defines an interior space holding a lubricant to lubricate the spline portion for sliding movement.
