A centered double universal joint comprises a housing having a first inner joint fork and a second inner joint fork, a first outer joint fork hingedly connected to the first inner joint fork via a first trunnion cross, a second outer joint fork hingedly connected to the second inner joint fork via a second trunnion cross, an annular recess in the housing disposed about a longitudinal axis of the housing, a guide disc that is guided in a radially adjustable manner in the annular recess of the housing, the two outer joint forks being coupled in an articulated manner to the guide disc, and two floating discs arranged in the axial direction on both sides of the guide disc in the annular recess, wherein the housing, the floating discs or the guide disc is/are magnetized, exerting a magnetic force on the floating discs in the direction of the longitudinal axis.

Disclosed is a toroidal variable speed traction drive including a driving disc and a driven disc, with a plurality of roller assemblies in between. Each roller assembly has a toroidal rolling surface to contact the toroidal surface of the corresponding disc, and a conical surface, for engaging the other roller in the assembly. An engagement is provide to prevent or reduce axial movement between the first and second rollers along the conical surface.

A joint assembly having a first shaft having an end and extending along a first axis and a second shaft having an end and extending along a second axis is provided. A first inner ring coupled to the first shaft, a second inner ring coupled to the second shaft, and a sleeve coupled to the first and second inner rings are also provided. The first and second inner rings are disposed within the sleeve and a centering device engages the ends of the first and second shafts. The centering device is configured to maintain the angular positions of the first and second shafts relative to the sleeve. The centering device is substantially fixed from rotation during rotation of the first and second shafts and the centering device includes a receiving socket defining a socket path, the socket path having a different orientation than the second axis.

A joint assembly includes a first shaft having an end, a second shaft having an end, a first inner ring coupled to the first shaft, and a second inner ring coupled to the second shaft. The assembly further includes a sleeve coupled to the first and second inner rings, the first and second inner rings disposed within the sleeve, and a centering device engaging the ends of the first and second shaft. The centering device is configured to maintain the angular positions of the first and second shafts relative to one another, and the centering device is substantially fixed from rotation during rotation of the first and second shafts.

A double cardan constant velocity joint including a housing extending between a housing first end and a housing second end. A first yoke is pivotably coupled to the housing first end by a first spider. The first yoke extends between a first end having a socket and a second end configured for attachment to a first shaft. A second yoke is pivotably coupled to the housing second end by a second spider. The second yoke extends between a first end having a ball stud and a second end configured for attachment to a second shaft. A ball is disposed in the socket, wherein the ball has a recessed pocket for receipt of the ball stud. A biasing member is disposed in the recessed pocket to impart a bias on the ball, wherein pivotal movement of the first yoke and the second yoke causes the ball to translate in the socket.

A joint assembly for use in a vehicle. The joint assembly includes a first joint member drivingly connected to a second joint member by one or more third joint members. The joint assembly further includes one or more bearing cup assemblies having a bearing cup, one or more bearings and one or more sealing members. The bearing cup has a receiving portion having a size and shape to receive and/or retain at least a portion of one or more trunnions extending from a body portion of the one or more third joint members. At least a portion of the one or more bearings are interposed between the one or more trunnions and one or more side surfaces of the receiving portion. Additionally, the one or more sealing members may be connected to and/or sealingly engaged with at least a portion of the outer surface of the one or more trunnions.
