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 first constant velocity joint is equipped with a cup part made of a light alloy. First ball grooves that receive a torque from torque transmitting members are formed on an inner wall of the cup part. A high hardness layer made of ceramic or cermet as a principal component thereof is formed on an inner surface of the cup part including at least inner surfaces of the first ball grooves.

Provided is a method of manufacturing an outer joint member of a constant velocity universal joint, which is constructed by forming a cup section having track grooves, and a shaft section, and by welding a cup member and a shaft member, the method including: forming the cup member and the shaft member of medium carbon steel; preparing a cup member having a cylindrical portion and a bottom portion integrally formed by forging, and a joining end surface in a machining step; preparing a shaft member having a joining end surface formed in a machining step; bringing the joining end surface of the cup member and the joining end surface of the shaft member into abutment against each other; welding the cup member and the shaft member by radiating a beam; and performing, after the welding, an ultrasonic flaw detection-inspection step.

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 connection arrangement for axially securing a shaft-hub connection includes a shaft, a hub, and a securing device. The hub has an inner stop surface for the shaft formed by a recess and has an outer groove for axially positioning the securing device. The securing device has an axially extending sleeve-shaped part at least partly surrounding the circumference of the hub and has a radial collar at least partly engaging behind the annular end surface of the hub. The sleeve-shaped part is surrounded by a tensioning strap. A holding socket region offset radially inwards surrounds the expanded outer groove of the hub coaxially in the assembled state and can be locked in the expanded outer groove of the hub by the tensioning strap. The radial collar of the holding socket rests against an axial securing ring of the shaft in the locked state.

A drive shaft includes a first shaft member made of metal, a tubular member made of CFRP, and a first exterior sleeve. The first shaft member is capable of being attached on one end side thereof to a first constant velocity joint, and has a first serrated part on which serrations are formed on another end side thereof. The tubular member is formed with a first fitting part fitted externally over the first serrated part. The first exterior sleeve covers the first fitting part by being disposed to extend over outer circumferential surfaces of the first shaft member and the tubular member. A film provided with a bonding assistance region and an adhesive are interposed between the outer circumferential surface of the tubular member and the inner circumferential surface of the first exterior sleeve.

A vehicle drive system comprises a first shaft and a second shaft that includes an opening configured to receive the first shaft. A shaft retention apparatus comprises a support component extending axially and along the outer contour of the outer surface of the first shaft and the outer surface of the second shaft, to bridge the two shafts at an intersection thereof. A first clip portion extends from the support component and engages a groove in the outer surface of first shaft and a second axially spaced clip portion extends from the support component and engages a groove in the outer surface of the second shaft, preventing prevent axial movement therebetween.

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.

Provided is a fixed type constant velocity universal joint, including: an outer joint member (10) having a cup-shape; and an inner joint member (20), which is received in the outer joint member (10), and is configured to transmit torque between the inner joint member (20) and the outer joint member (10) through intermediation of balls (30) while allowing angular displacement. The fixed type constant velocity universal joint has a shaft (50) extending from the inner joint member (20). The shaft (50) includes a large-diameter portion (51), which is formed integrally with the shaft (50), and interferes with the balls (30) when the shaft (50) forms an operating angle, which is larger than a maximum operating angle, with respect to the outer joint member (10).
