ABSTRACT:
A nonlinear torsional spring includes an inner torsion member and an outer torsion member. The inner torsion member includes a central axis and has first and second axial ends and the outer torsion member is fixedly secured to the inner member adjacent the first end thereof and extends along the inner member toward the second end. At least one projection and groove are provided in the arrangement for causing the inner member and the outer member to contact one another along the length of the inner member at a position progressively nearer the second end thereof as torque is applied to one of the inner and outer members. The spring may be used as a stabilizer bar in a vehicle and the like or employed in a machine as a nonlinear torsional spring element.
