ABSTRACT:
A torsional spring 10 includes an outer cylinder 12 connected to a central hub 14 through a series of elastomeric spokes 16-30. The elastomeric spokes 16-30 extend from the inner periphery of the cylinder 12 to the hub 14 substantially along a line tangential to the central hub 14. Further, each of the elastomeric spokes 16-30 includes first and second radial segments wherein the first radial segment is adjacent the hub 14 and has an elastic modulus that is lower than the second radial segment.
