Abstract
A leaf spring suspension for a motor vehicle wherein the leaf spring has one end pivotally connected to the frame and the other end also connected to the frame via a torsion spring member. The torsion spring member has a shaft member which is pivotally connected to the other end of the leaf spring. The torsion spring member has an elastomeric sleeve whose inner bore surface is bonded to the shaft member. The torsion spring member also has an outer shell secured to the sleeve and also connected to the frame. A stop member is mounted on the outer shell for engagement by an abutment member on the bracket member to cut out the torsion spring and place the leaf spring in sole control as the suspension.
