Title (EN) SEAL ASSEMBLY
(FR) ENSEMBLE D"ETANCHEITE
Abstract: front page image
(EN)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).
(FR)Un ensemble d"etancheite pour des structures telles que des joints de chenille, des liaisons de chargeurs et des suspensions de chassis sert a maintenir un joint de pression entre deux composants deformables sur une plage relativement grande d"amplitude de flexion. Des dispositifs d"etancheite anterieurs etaient efficaces seulement sur un degre limite de flexion a cause de leur incapacite a maintenir un degre desire de compression sur une grande plage de flexion. L"ensemble d"etancheite decrit presente un joint elastique (84) dispose dans un evidement ouvert annulaire (82) defini dans un premier organe (56). Un second organe est dispose adjacent a l"ouverture de cet evidement (82) et peut flechir vers et en retrait de cette ouverture de l"evidement (82). Des moyens (90) disposes l"evidement (82) et sensibles a l"ecartement entre le premier membre (56) et le second membre (74) operent la flexion deflechissement du joint (84) du premier organe (56) et du second organe (74), sensiblement sur toute la plage de flexion des organes (56, 74).
