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.
