Abstract
An airspring for motor vehicles which includes a pair of spaced end members with an intervening flexible elastomeric sleeve forming a fluid pressure chamber therebetween, for absorbing shock forces exerted on the vehicle caused by variations in the surface of the roadway. An elongated flexible strap of synthetic fabric such as nylon, is formed as a closed loop and is connected to and extends between the end members within the pressure chamber. The flexible strap limits the expansion of the flexible sleeve in an extended direction to prevent damage to the airspring without effecting the external configuration of the airspring and without materially effecting movement of the airspring in the jounce direction.
