Abstract: A driveshaft assembly includes a driveshaft tube having two ends. An end fitting is operatively connected to one of the two ends of the driveshaft tube. A torque control mechanism is operatively connected to the end fitting. The torque control mechanism includes an outer member defining a first conical surface extending circumferentially relative to a central axis. The torque control mechanism includes an inner member defining a second conical surface extending circumferentially relative to the central axis. The first conical surface is configured to be in contact with the second conical surface so as to transfer a torque load from the inner member to the outer member. The second conical surface is configured to rotate relative to the first conical surface along the central axis at a slip angle when the torque load exceeds a predefined maximum torque load.

Abstract: A vehicle, a prop-shaft and a method of reducing noise in a vehicle are provided. The prop-shaft includes a cylindrical shaft having a hollow interior. A liner is positioned within at least a portion of the hollow interior. A first retaining member is disposed adjacent an end of the liner, the first retaining member sized to inhibit movement of the liner in a first direction. A second retaining member is disposed adjacent an opposite end of the liner from the first retaining member, the second retaining member sized to inhibit movement of the liner in a second direction, the second direction being opposite the first direction.

Abstract: A transaxle for a vehicle includes an input driven shaft that extends along a drive axis, between a first end and a second end. The input driven shaft is rotatable about the drive axis. A first planetary gear train is coupled to the first end of the input driven shaft, and a first motor is coupled to the first planetary gear train. A second planetary gear train is coupled to the second end of the input driven shaft, and a second motor is coupled to the second planetary gear train. The first motor and the second motor provide torque to the first planetary gear train and the second planetary gear train independently of each other to provide a differential functionality and allow torque vectoring between drive wheels.
