A wheel drive assembly for transferring propelling torque from a source shaft to a wheel, the source shaft receiving torque from a motion actuator. The wheel drive assembly includes a wheel-hub, adapted to have the wheel mounted thereon, the wheel-hub being arranged about a longitudinal axis, which is adapted to coincide with a rotation axis of the wheel. The wheel drive assembly further includes a drive axle and a constant velocity (CV) joint mounted onto an outer end of the drive axle. The CV joint connects the drive axle to the wheel-hub. An outermost surface of the CV joint is disposed outwardly of an outermost surface of the wheel hub, along the longitudinal axis of the wheel-hub.

A spline connection having a hub with a toothing profile on the inner circumference, an axle journal having a toothing profile on an outer circumferential portion, a shoulder for axial support and/or abutment against the hub, and a tensioning device for axially bracing the axle journal with the hub. The hub has a constant toothing profile and the axle journal has a first portion and a second portion with different toothing profiles. The first portion is arranged on the insertion side to be further away from the shoulder than the second portion and has a constant toothing profile with play with respect to the toothing profile of the hub. The second portion is arranged on the shoulder side and has a toothing profile which has reduced tooth spaces compared with the first portion and which is play-free with respect to the toothing profile of the hub.

A wheel bearing arrangement for a motor vehicle with a wheel hub and a wheel bearing for the rotatable bearing of the wheel hub at a wheel mount. The wheel bearing has an outer ring and an inner ring, which is rotatable with respect to the outer ring around an axis of rotation and is connected to the wheel hub. A wheel flange extends from the wheel hub and, as viewed in the axial direction, has a brake disk mount, which is open in the direction facing away from the outer ring and which, as viewed in longitudinal section with respect to the axis of rotation, is formed by a recess of the wheel flange, and has a support surface for a brake disk.

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.

A joint arrangement includes comprising a joint, a nut and an adapter unit. The joint has an inner hub, an outer hub, balls and a cage with recesses for the balls. The inner hub has a recess with an inner toothing for receiving a first shaft. A cavity of the joint arrangement located around the balls is closed on two end sides by a respective sealing device. The adapter unit includes a first adapter portion and a second adapter portion which cooperate to transmit torque across the joint arrangement to or from a second shaft.

A propeller shaft (1), as a power transmitting shaft, of the present invention is configured such that a snap ring (8) as a retaining ring can be inserted inwards into a first penetration slot (31) formed at a tubular portion body (33) of a tubular portion (30) from a radial direction outer side. With this, good workability of assembly of the snap ring (8) is secured. Further, an engagement-stop state of a second shaft (3) by the snap ring (8) can be visually checked from the outside through the first penetration slot (31), then check of an engagement state by the snap ring (8) can be made.

A propeller shaft includes: an outer race having a plurality of bolt holes formed therethrough in an axial direction; a power transmission member swingable in the outer race; a shaft member having a front end portion in which a large-diameter portion is formed and a rear end portion connected to the power transmission member; a seal member made of rubber and configured to seal a front opening of the outer race; and a disc-shaped protection member mounted between the large-diameter portion and the rear end portion of the shaft member. In one aspect, the protection member has a clearance portion for a bolt fastening tool, and the clearance portion is annually formed around a shaft center. In another aspect, the protection member has clearance portions for a bolt fastening tool, and each of the clearance portions is in phase with a corresponding bolt hole when viewing in the axial direction.

Hub bearing constant velocity joint in which a radially outer, annular, element of the joint is engaged with an annular hub of a hub bearing unit with a flange at a first end thereof by means of a clamping system including a screw element assembled inside the annular joint element and able to be operated on the outer side through the annular hub so as to screw it inside a second end of the hub until it prestresses the rolling bodies of the hub bearing unit, while the transmission of torque is ensured by a splined coupling between the joint element and the second end of the hub; the screw element is axially locked against an annular shoulder formed on the inside of the joint element, on the opposite side to the annular hub, by means of an elastic ring engaged with at least one annular seat formed on the inside of the joint element.

A constant-velocity joint assembly for a power tool includes an output shaft and a coupling structure configured to drive the output shaft. The output shaft and the coupling structure form a joint configured to enable angling of the output shaft relative to the coupling structure at constant rotational speed, and the coupling structure is provided with a torque transducer configured to detect a torque acting on the coupling structure provided by the output shaft.

A joint assembly (200) comprising a first joint member (232) that is drivingly connected to a second joint member (272) by one or more torque transfer elements (290). Drivingly connected to at least a portion of the second joint member (312) is a stub shaft (292). An end of the stub shaft, opposite the second joint member, is drivingly connected to at least a portion of a second shaft. At least a portion of a second end portion of a first shaft (202) is drivingly connected to at least a portion of a first end portion of the first joint member (232) and at least a portion of a first end portion of the first shaft has a gear member (210) with a plurality of gear teeth thereon.
