摘要： A motor vehicle shaft assembly has a shaft extending along a longitudinal axis between opposite ends, with the shaft having a male spline adjacent at least one of the opposite ends, and a housing having a through bore extending about the longitudinal axis, with the through bore having a female spline configured for meshed engagement with the male spline to prevent relative torsional movement between the shaft and the housing. At least one of the male and female splines includes a tapered spline extending in oblique relation to the longitudinal axis.

摘要： A boot for a shaft assembly joint and method of construction thereof are provided. The boot has a flexible hollow wall extending about a central axis between a first end and a second end. The first end has a skirt portion configured for snug engagement with an outer surface of a housing of the constant velocity joint and the second end has a neck portion configured for snug engagement with an outer surface of a shaft extending away from the constant velocity joint. At least one of the skirt portion and the neck portion has interior surface formed of a first material having a first coefficient of friction and an exterior surface formed of a second material having a second coefficient of friction, the first coefficient of friction being greater than the second coefficient of friction.

摘要： A constant velocity joint assembly includes an inner annulus having a first race and an outer annulus having a second race supporting the first race for pivotal movement relative to the second race about a pivot axis. A third race is provided by the outer annulus and a fourth race is provided by an interface member. A ball spline is disposed between the third race and the fourth race for axial stroking movement of the third race relative to the fourth race, wherein the ball spline is axially offset from the pivot axis. Separate boots seal and isolate the pivotal movement and the stroking movement from one another.

摘要： A half shaft system includes first and second universal joints, a shaft, a torque sensor device, and computing circuitry. The shaft is engaged to, and extends between, the first and second universal joints. The shaft is adapted to rotate about an axis. The torque sensor device is attached to the shaft, and includes a torque sensor and a transmitter. The torque sensor is configured to measure torque placed upon the shaft. The transmitter is configured to wirelessly output torque signals indicative of the measured toque. The computing circuitry is configured to receive the torque signals, process the torque signals, establish a load history of the half shaft assembly from the processed torque signals, compare the load history to a pre-programmed life model, and estimate a service life of the half shaft assembly from the load history.

摘要： A tripot constant velocity joint includes a housing defining a guide channel. A spider member is received within the housing and includes a trunnion having a functional outer surface with a convex profile defined by a first principal radius of curvature and a second principal radius of curvature different from the first principal radius of curvature. A first inner surface of a first ball member engages the functional outer surface of the trunnion. A first outer surface of the first ball member is provided with a non-symmetric piecewise continuous profile that engages the first sidewall.

摘要： A universal or constant velocity joint includes a first rotatable shaft member that extends along a longitudinal axis, a bearing member, and a joining member. The first rotatable shaft member has a free end that defines a shaft face spline. The bearing member includes a bearing hub having a first end, a second end, and a longitudinally extending hub bore. The first end has a hub face spline. The joining member fixes the bearing member to the shaft with the hub face spline and shaft face spline engaged in interlocking engagement.
