A seal assembly for sealing between a first member (12) and a second member (14) of a joint, the first member (12) being able to pivot about an axis (50) of the joint relative to the second member (14), is disclosed. The seal assembly includes a first ring (26), a load ring (20), a first seal ring (22), and a resilient second seal ring (24). The first ring (26) is for a first seal cavity (52) of the first member (12). The load ring (20) is for a second seal cavity (54) of the second member (14). The first seal ring (22) may be of a metal having a sealing surface (34) extending in a radial direction. The resilient second seal ring (24) may have an annular seal lip (18). The first seal ring (22) is held stationary by the first ring (26) in the first seal cavity (52) of the first member (12), and the second seal ring (24) is forced axially by the load ring (20) into axial sealing engagement with the first seal ring (22). A track joint may include such a seal assembly and a vehicle may include such a seal assembly. The first seal ring (22) may be integral with a thrust ring (40). |
