  • Patent number: 11493091
    Abstract: A shaft assembly. The shaft assembly includes a joint assembly having a first joint member, a second joint member and one or more third joint members drivingly connecting said first and second joint members. At least a portion of a first shaft is drivingly connected to the second joint member. Circumferentially extending from at least a portion of an outer surface of a second end portion of the first shaft is a first and second increased diameter portion having a wall portion that connects the first increased diameter portion to the second increased diameter portion. Drivingly connected to the second increased diameter portion of the first shaft is a second shaft. During a crash condition, an amount of force is applied to the wall portion until it fractures and at least a portion of the first shaft and/or the joint assembly translates into a hollow portion of the second shaft.

  • Patent number: 11242897
    Abstract: A coupling assembly having a first member drivingly connected to a second member via one or more third members. A first shaft is drivingly connected to the first member and a second shaft is drivingly connected to the second member. The second member includes a flange portion having one or more seating portions on a first end portion of the flange. Additionally, the flange has one or more flange portion attachment apertures extending from the seating portions to a second end portion of the flange. An increased diameter portion of the second shaft has one or more increased diameter portion apertures extending from a first end portion to a second end portion. The flange portion apertures and the increased diameter portion apertures have a center-line with an angle from an axial center-line of the assembly. Additionally, the seating portions have an angle relative to a radial center-line of the assembly.

  • Patent number: 7520814
    Abstract: A cross for a universal joint includes a body portion having a trunnion that extends outwardly therefrom. The trunnion includes a surface. A bearing cup is mounted on the trunnion. A retainer includes a first portion that is supported on the bearing cup, a second portion that extends at an angle from the first portion, and a third portion that extends at an angle from the second portion into engagement with the surface of said trunnion. The retainer allows the assembly of the bearing cup and the retainer to be installed on the trunnion with a relatively small force, but requires a relatively large force to remove the assembly of the bearing cup and the retainer from the trunnion.
