ABSTRACT:
A shock absorber for a vehicle is provided with an elongated rod which is longitudinally displaceable with respect to a carrier which supports at least one frictional rod engagement member for producing a rod travel retardation force. The rod engagement member is arranged to apply a lateral force to the rod, which lateral force is translated into the rod travel retardation force to smoothly and quickly control the motion of the rod between first and second positions. The frictional rod engagement member can be urged against a rod in various ways, including compression of a resilient or elastic force exerting component, such as a wire-wound spring. The combination of the force exerting components and the frictional member can be configured to apply retardation forces to the rod which have preselectable damping characteristics. In a featured embodiment of the invention, the resilient force exerting component is itself damped by contact with the frictional rod engagement member.
