ABSTRACT:
A telescoping torque transmitting shaft has an outer shaft element non-rotatably and slidably mounted upon an inner shaft element and both shaft elements have conforming cross-sections. A tubular shaft is concentrically arranged about the outer shaft element and the opposing surfaces of the tubular shaft and the outer shaft element are provided with axially extending grooves in which are positioned a plurality of linearly arranged torque transmitting balls. Springs are mounted on the tubular shaft to limit the axial movement of the balls in each groove and a restoring spring biases the tubular shaft and the outer shaft element to a predetermined axial position with respect to each other.
