  • Publication number: 20140213374
    Abstract: A high angle constant velocity joint having an outer joint member defined by inner and outer surfaces; an inner joint member having an outer surface, wherein the inner surface of the outer joint member and the outer surface of the inner joint define tracks, including a front track and a rear track for a joint articulation; a cage disposed between the outer joint member and the inner joint member and positioned adjacent to the tracks; a plurality of torque transmitting bails arranged within the cage and contacting at least one of the front track and the rear track; and a high angle sealing member secured to the outer surface of the outer joint member and providing a fluid barrier to the inner surface of the outer joint member.

  • Patent number: 8221251
    Abstract: An articulated joint includes a first rotational member and a second rotational member coupled with and positioned generally coaxial to the first rotational member. The joint also includes a boot. The boot is selectively deformable in response to an increase in pressure in a joint chamber to increase the volume of the joint chamber. The volume of the joint chamber is selectively changed due to, at least in part, relative movement of the boot end to the second rotational member.

  • Patent number: 8157657
    Abstract: A barrier membrane assembly for sealing a constant velocity joint assembly includes at least one selectively expandable and contractible barrier membrane body. The barrier membrane body has no openings therethrough and may selectively expand and contract in response to operational pressures acting against the barrier membrane body.
