ABSTRACT:
A linear vibration isolator between a pair of shaft segments of a motor vehicle intermediate steering shaft including an outer member rigidly connected to one of the shaft segments, an inner member rigidly connected to the other of the shaft segments and cooperating with the outer member in defining an annular chamber therebetween, and an axially flexible and torsionally stiff disc pack in the annular chamber. The disc pack includes a plurality of flat outer spacer rings, a plurality of flat inner spacer rings nested inside of the outer spacer rings, and a plurality of elastomeric isolator discs stacked between the nested pairs of inner and outer spacer rings. The outer spacer rings with the isolator discs therebetween are clamped against a shoulder on the outer member and coupled to the outer member for unitary rotation therewith. The inner spacer rings with the isolator discs therebetween are clamped against a shoulder on the inner member and coupled to the inner member for unitary rotation therewith. The effective axial flexibility and torsional stiffness of the disc pack is determined by the physical characteristics of and the number of isolator discs and inner and outer spacer rings.
