ABSTRACT:
A torsional sleeve coupling provides a spring system for dampening torsional vibrations in a driveline coupling during low torque modes of operation. In a preferred form, the coupling is adapted for use with a driving and a driven shaft which are coaxially aligned. The coupling includes a lost motion connection for torsionally coupling the driven and driving shaft ends for joint rotation. In a preferred embodiment, the coupling incorporates a sleeve which contains a C-spring having an annular metallic body positioned in coaxial registration with one of the shafts. The spring includes a pair of spaced, radially oriented ears. The sleeve and the shaft about which the spring is positioned each contain a slotted portion. The two slotted portions are in radial alignment with each other, and each is adapted to receive both of the ears of the spring.
