摘要： In accordance with at least one aspect of this disclosure, a composite shaft includes a plurality of composite elements arranged about an axis to form a hollow shaft with at least one undulation. The plurality of composite elements incudes a first group of the composite elements arranged about the axis offset by an angle +α and a second group of the composite elements arranged about the axis offset by an angle −α to form a web with the first group of composite elements. The first and second groups of the plurality of composite elements are configured to cooperate with one another to allow the hollow shaft to be flexible under axial load and stiff under rotational load.

摘要： A tube is used in fiber-reinforced plastic power transmission shaft. The tube comprises: a cylindrical body section; a connection portion that has a larger diameter than the body section; and an inclined portion that has an outer diameter that increases toward the second connection section from the main body part. The inclined section has formed thereon, a weak section that is damaged when a load input in the axial direction exceeds a prescribed value. With this configuration, the cost of the tube can be reduced, and when a prescribed load is input to the tube in the axial direction, the tube is reliably damaged.

摘要： 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.

摘要： A drive unit is disclosed that includes case portions, a gasket interposed between the case portions, shafts, bearings having respective bearing races, and a bearing shim plate. One shaft includes an input oil tube which provides a fluid pathway between the bearing shim plate and a rotor of the drive unit. Interposed between bearings, and the bearing shim plate, are shims. An approach for sizing shims for use with a drive unit is also disclosed, the approach including determining the distance from a mating flange of a case portion, to different bearing races, selecting shims based on the determined distances, and attaching the bearing shim plate to the case portion with shims interposed therebetween.

摘要： A vehicular propeller shaft is configured to transmit a rotational force output from a drive force source to drive wheels. The vehicular propeller shaft includes a stepped pipe-shaped member including a compressive load weakest part with respect to an axial compressive load of the vehicular propeller shaft and a torsional load weakest part with respect to a torsional load around an axis of the vehicular propeller shaft. The compressive load weakest part and the torsional load weakest part are positioned apart from each other in a radial direction of the stepped pipe-shaped member.

摘要： A carrier bearing assembly can include a bracket comprising a first end, a second end, a first face extending between the first end and the second end width, and a second face opposite the first face. An opening can be formed completely through the bracket and extend from the first face to the second face. A bearing can be disposed within the opening and an angle between a centerline of the bearing and a centerline of the bracket can be in a range of 85-89° or 91-95°. First and second mounting structures offset from the opening can be for coupling the carrier bearing assembly to the frame of the UTV, and the centerline of the bracket can pass through a center of the first mounting structure and a center of the second mounting structure.

摘要： An intermediate bearing for a drive shaft train of a motor vehicle has an elastic bearing body which has a bore and a supporting ring which is arranged in the bore and has a receiving space for receiving an anti-friction bearing. The receiving space defines a longitudinal axis, and two sealing washers which are spaced apart axially from one another and have in each case one central opening for receiving a drive component. The supporting ring is arranged between the two sealing washers. The sealing washers have in each case one groove which extends concentrically with respect to the longitudinal axis. The supporting ring engages into the two grooves of the sealing washers.

摘要： A pillow block bearing assembly for a drivetrain assembly of a work vehicle may include a pillow block housing defining a bearing cavity, a bearing disposed within the bearing cavity, and first and second sealing devices installed within the bearing cavity. Additionally, the drivetrain assembly may include a shaft received within the pillow block bearing assembly, with the shaft extending through the bearing such that an outer circumferential surface of the shaft directly contacts an inner circumferential surface of an inner race of the bearing at a bearing/shaft interface defined between the shaft and the bearing. Moreover, a sliding fit may be defined between the outer circumferential surface of the shaft and the inner circumferential surface of the inner race at the bearing/shaft interface such that the shaft is allowed to slide axially relative to the bearing when a given axial load is applied through the shaft.
