A power transmission shaft comprises a shaft unit interposed between first and second shafts; an engaged portion provided on one end of the second shaft and having an annular stepped part provided between a smaller diameter portion and a larger diameter portion; and an engaging portion provided on one end of the shaft unit and joinable with the engaged portion to rotate together about a common rotation axis, wherein the engaging portion comprises a cylindrical base portion that rotates together with the shaft unit, an elastically shrinkable cylindrical portion that is provided on one axial end of the cylindrical base portion to project toward the engaged portion and catching pawls that are provided by the elastically shrinkable cylindrical portion and latchingly engageable with the annular stepped part when the engaged portion and the engaging portion are coaxially arranged and joined with each other.

A shaft connection 1 for a longitudinal shaft assembly, has at least a first shaft having a first and second ends, and a second shaft, disposed so as to be coaxial with the first shaft, having first and second ends; the shafts extending axially. The first end forms a hollow portion. The first shaft end forms a first journal having a displacement portion. The first shaft end at least in an initial position of the shaft connection extends through the hollow portion which axially by the displacement portion forms a guide portion and circumferentially forms a form-fitting first connection. In the initial position a mutual axial displacement of the first and second shafts is prevented by an axial securing feature. In a crash the axial securing feature; is releasable by an axial release force. The first shaft is axially displaceable relative to the second shaft.

A constant velocity housing is provided to couple a plunging CV joint with a transaxle. The constant velocity comprises an elongate housing configured to retain the plunging CV joint and a splined shaft configured to engage with a transaxle. A locking system removably retains the splined shaft within the transaxle. The locking system comprises a lock pin in mechanical communication with pins slidably retained within radial holes disposed in the splined shaft underneath a snap-ring. An actuator moves the lock pin to push the pins to operably change a diameter of the snap-ring. When the actuator is loosened, the snap-ring constricts to a diameter less than the diameter of the splined shaft, allowing removal of the splined shaft from the transaxle. When the actuator is fully tightened, the snap-ring assumes a diameter greater than the diameter of the splined shaft, such that the spline shaft remains engaged with the transaxle.

A joint assembly for use in a motor vehicle. The joint assembly includes a first joint member that is drivingly connected to a second joint member via one or more third joint members. At least a portion of the first joint member is drivingly connected to at least a portion of a first shaft and at least a portion of the second joint member is drivingly connected to at least a portion of a second shaft. One or more first joint member tool grooves circumferentially extends along the outer surface of the first joint member. The joint assembly further includes a nut that drivingly connects at least a portion of a third shaft to at least a portion of the second shaft. The nut includes one or more nut tool grooves circumferentially extending along the outer surface of the nut.

A constant velocity universal joint includes outer and inner joint members that transmit torque while allowing angular displacement via balls, a power transmission shaft connected to the inner joint member in a torque transmittable manner, and a detachable mechanism between the inner joint member and the power transmission shaft to detach the power transmission shaft from the inner joint member. The detachable mechanism includes a cylindrical member externally fit onto the power transmission shaft, spheres movable in a radial direction in the cylindrical member, and an annular member movable in an axial direction on an outer periphery of the cylindrical member. Locking claws are provided at an end of an inner joint member side of the annular member, and a locking groove is provided at an end of an annular member side of the inner joint member. The locking claws are fitted into the locking groove.

A constant velocity universal joint includes outer and inner joint members configured to transmit torque therebetween through intermediation of balls while allowing angular displacement. A power transmission shaft is coupled to the inner joint member. A mounting and dismounting mechanism configured to mount and dismount the power transmission shaft to and from the inner joint member is provided between the inner joint member and the power transmission shaft. The mounting and dismounting mechanism includes a tubular member inserted externally on the power transmission shaft so as to extend from the inner joint member, a fixing member received in the tubular member, and an annular member arranged on an outer periphery of the tubular member. The fixing member is moved in the radial direction along with movement of the annular member in the axial direction so that the fixing member is mountable to and dismountable from the power transmission shaft.

A propeller shaft as a power transmission shaft is provided between vehicle-side first second shaft parts, and a first tube as a first shaft member is connected to the first shaft part through a first joint member and to the second shaft part through a second joint member. The first tube is connected to the first joint member through a first collar member and to the second joint member through a second collar member. The first collar member includes a first main body part exposed from a first end portion of the first tube, and a first insertion part inserted into the inside of the first end portion. In at least the first collar member, the maximum value of the outer diameter of the first main body part is set to be no greater than the maximum value of the outer diameter of the first insertion part.

A shaft connection 1 for a longitudinal shaft assembly, has at least a first shaft having a first and second ends, and a second shaft, disposed so as to be coaxial with the first shaft, having first and second ends; the shafts extending axially. The first end forms a hollow portion. The first shaft end forms a first journal having a displacement portion. The first shaft end at least in an initial position of the shaft connection extends through the hollow portion which axially by the displacement portion forms a guide portion and circumferentially forms a form-fitting first connection. In the initial position a mutual axial displacement of the first and second shafts is prevented by an axial securing feature. In a crash the axial securing feature; is releasable by an axial release force. The first shaft is axially displaceable relative to the second shaft.

A constant velocity joint includes an external joint part including internal ball tracks, an internal joint part including external ball tracks assigned to the internal ball tracks, and a ball cage holding balls. The external joint part is connectable to a connecting part and sealed by a closure cap on the side facing this connecting part. The internal joint part is an integral internal joint part connected permanently to a shaft piece, sealed on this side towards the external joint part by a flexible sealing element, hardened, and has a protruding welding attachment for an adapter on its free end. The welding attachment outer diameter is larger than the smallest integral internal joint part outer diameter. In a method, the sealing element is mounted over the integral internal joint part free end and connected to the external joint part, the adapter subsequently welded near the welding attachment.

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.
