Abstract
PCT No. PCT/US79/00026 Sec. 371 Date Jan. 18, 1979 Sec. 102(e) Date Jan. 18, 1979, PCT Filed Jan. 18, 1979 PCT Pub. No. W080/01505 PCT Pub. Date July 24, 1980. A seal (16) is positioned to prevent entry of foreign matter through an annular opening (26) between first and second members (12,14). The first and second members (12,14) are, for example, a stationary backing plate (20) and a rotatable hub (22) of a brake assembly (24) or a rotatable shaft and associated housing element. Foreign matter passing between the backing plate (20) and the hub (22), for example, can enter an associated brake drum (30) and interfere with effectiveness of the brake assembly (24). Apparatus (72) connects the seal (16) to the backing plate (20). The seal (16) has first and second legs (38,40) each having a sealing surface (58,60). The sealing surface contact a face (68) and outer surface (66) of the hub (22), respectively, to substantially block passage of foreign matter to the brake drum (30).
