PCT No. PCT/EP87/00660 Sec. 371 Date Jun. 28, 1988 Sec. 102(e) Date Jun. 28, 1988 PCT Filed Nov. 3, 1987 PCT Pub. No. WO88/03618 PCT Pub. Date May 19, 1988.A suspension spring system includes a housing, a suspension spring located in the housing and a bistable control spring located in the housing. A load supporting member is positioned at least partially within the housing and is movable with respect to the housing. The control spring is radially compressed within the housing so that the control spring is prestressed. The control spring is shiftable between two stable final positions and is, thus, able to influence and control the spring characteristics of the suspension spring.
