摘要： A shear seal assembly (80) for sealing between two members (22, 36) having limited relative motion therebetween has an inner sleeve (86), an outer sleeve (88), and an elastomeric member (90) connecting the sleeves (86, 88). The inner sleeve (86) is in a press fit relationship with one of the members (22) and the outer sleeve (88) is in a press fit relationship with the other of the members (36). Thrust members (92, 93) extending radially outwardly along the sides (94, 96, 98, 99) of the seal assembly (80) control distortion thereof and prevent damage thereto. A protective member (93, 100) prevents the ingress of external contaminants and abrasives into the area to be sealed.

摘要： A shear seal assembly (65) has an inner sleeve (66) and an outer sleeve (68) with an elastomeric material bonded therebetween. One sleeve (66, 68) has a circumferential groove (74) formed in the exposed wall (76) thereof in which groove (74) an O-ring (78) nests. The assembly is mounted between two telescopic members (28, 38) that have limited relative rotation. The sleeve without the groove (74) is press fit on or in one member (28, 38) and the sleeve (68) with the groove (74) will be spaced from the other member (28, 38) so that the O-ring (78) will extend from the groove (74) into sealing contact with said other member (28, 38). Clips or retainers (82) are provided for seating the grooved sleeve (66, 68) to said other member (28, 38) whereby limited relative rotation or oscillation between the members takes place without rupturing the elastomeric material. The shear seal can be removed without destroying the shear seal structure so that it can be reused.

摘要： Roller suspension apparatus are useful for example in belted vehicles. The heretofore known roller suspension apparatus impart a shear force to the spring due to the geometry and the relationship between the roller mounting arms, the walking beam, and the pivot pins to which the arms and beam are pivoted. The subject roller suspension apparatus has a pair of arms (34, 36) and a force transmitting beam (40) pivotally connected to a single pivot shaft (32). The mounting surfaces (46, 50, 51) to which a pair of springs (42) are attached are then arranged relative to the pivot shaft such that substantially only compressive forces are imparted to the springs. Thus, the full shock absorbing potential of the springs is fully utilized.
