<p>Seal assembly for such structures as track joints, loader linkages and undercarriage suspensions for maintaining a pressure seal between two deflectable components over a relatively wide range of deflection. Previous seal arrangements have been effective over only a limited degree of deflection due to their inability to maintain a desired degree of compression over a wider range of deflection. A seal assembly is disclosed wherein a resilient seal (84) is disposed within an open annular recess (82) defined in a first member (56). A second member is disposed adjacent to and is deflectable toward and away from the recess (82) opening. Means (90) within the recess (82) and responsive to the spacing between the first (56) and second (74) members are effective to deflect the seal (84) of the first (56) and second (74) members over substantially the entire range of deflection of the members (56, 74). </p> |
