  • Patent number: 8336887
    Abstract: A seal assembly disposed between relatively rotating members such as a rotating shaft passing through an opening in a stationary housing. The seal assembly may include a housing, such as a canister, and a seal member retained in the canister. The seal member may include an inner portion and an outer portion interconnected by a flexible wall and an aperture for receiving the shaft. The flexible wall may permit the inner portion to move relative to the outer portion of the seal member. The inner portion of the seal member may forms a seal with the shaft, and the seal member may rotate with the shaft within the canister. The seal assembly may engage an oil seal and may function as an excluder seal.

  • Patent number: 6959623
    Abstract: A park brake cable system including a brake actuation lever, a connector clip having a first end and a second end, and including a shear member, having a shear failure force, positioned between the first and second ends. A brake assembly, a front cable strand having a first end and a second end, the first end attached to the brake actuation lever, and the second end engaging the shear member on the connector clip are also included. Further included are a rear cable strand having a first end and a second end, the first end attached to the second end of the connector clip and the second end attached to the rear brake assembly, and a tensioner is attached in a tension force transmitting relationship with the front cable strand and the rear cable strand. Applying tension to the front and rear cable strands by the tensioner creates at least the sufficient shear failure force to cause the second end of the front cable strand to break the shear member and move to the first end of the connector clip.

  • Patent number: 5713579
    Abstract: A radial seal and facial excluder seal are mounted on separate rings but installed in combination so that the excluder seal always maintains sealing engagement with its intended counterface notwithstanding wide axial assembly tolerances between the shaft and bore on which the seals are mounted, the excluder seal also serving to prevent contamination from coming into contact with the radial seal, and the ring on which the excluder seal is mounted serves as a guide for installation of the shaft past the radial seal in such a way as to reduce occurrence of damage to the radial seal as a result of sharp splines or other imperfections on the shaft.

  • Patent number: 5687972
    Abstract: A unitary oil seal assembly intended for installation between relatively rotating inner and outer concentric members, such as, a shaft and housing of a motor vehicle is made up of a combination of a radial seal engageable with the shaft and a facial axial seal engageable with a rotating counterface and forming a part of a seal body which is mounted within the bore of a housing, a fixed axial relationship being maintained between the radial seal, facial seal and their respective sealing surfaces notwithstanding relative axial movement or misalignment between the shaft and housing.

  • Patent number: 5655781
    Abstract: A unitized radial and facial seal assembly intended for use between radially inner and outer relatively rotationally and axially movable members includes a facial seal which is disposed between axially spaced, radially extending flanges of a counterface and a retainer to prevent entry of external contaminants, a radial seal mounted on a casing and fixed against relative rotational and axial movement, and a wiper seal on the counterface which is disposed in sealing engagement with the radially inner member. One or more bearing members are disposed on the counterface for conjoint rotation with the radially inner member and cooperate with the wiper seal in maintaining a fixed axial relationship between the counterface and retainer. The relationship is such that the seals that rotate relative to their sealing surfaces are not exposed to axial reciprocation and the seals that undergo axial reciprocation are not exposed to relative rotation with respect to a sealing surface.

  • Patent number: 5421592
    Abstract: A unitized radial and facial seal assembly intended for use between radially inner and outer relatively rotationally and axially movable members includes a counterface for securement to the radially inner member and a bearing fixed to the counterface for conjoint movement therewith. An axially compressible facial seal is captured between axially spaced, radially outwardly extending flanges of the counterface and the retainer to prevent entry of external contaminants. A radial seal is mounted on a casing fixed against relative rotational and axial movement while sealingly engaging the radially inner member. In an installed condition, the radial seal, casing, retainer, and facial seal are all fixed against relative rotational and axial movement to the radially outer member. The counterface and bearing are secured for conjoint rotation with the radially inner member. The seal components form a secondary labyrinth seal to prevent any contaminants which do pass by the facial seal from reaching the radial seal.
