ABSTRACT:
The present invention concerns an air spring and jounce shock assembly for use in an automotive vehicle suspension system. The assembly may include a base adapted to be mounted on one of an axle assembly and a suspension component, a top cap adapted to be attached to a vehicle frame, and a diaphragm disposed between and attached to the base and the top cap, with the diaphragm including an inner surface defining a first portion of a compressed air cavity. A jounce shock reaction surface defines a second portion of the compressed air cavity and is included in a one of the top cap and the base. A jounce shock assembly is disposed in the air cavity in opposed relation to the jounce shock reaction surface and affixed to an other of the top cap and the base, with the jounce shock assembly including a body, affixed to the other of the top cap and the base and defining a compressed gas chamber, and a rod having a first end portion in the compressed gas chamber sealably engaged with and slidable relative to the body and a second end portion telescopically slidable from the body and located to selectively engage the jounce shock reaction surface.
