A profiled wheel assembly for coupling to a shaft includes a profiled wheel having a first guide slot extending radially outwardly from a central aperture of the profiled wheel and a first assembly slot spaced apart from and parallel to the first guide slot. A retainer is supported on the profiled wheel for movement between a lock position wherein the retainer axially locks the profiled wheel relative to the shaft and a release position wherein the retainer axially unlocks the profiled wheel relative to the shaft.

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 constant velocity universal joint has an outer joint member and an inner joint member that transmits torque while permitting angular displacement due to balls between the inner and outer joint members. An attaching and detaching mechanism for attaching and detaching a power transmission shaft to and from the inner joint member is provided between the inner joint member and the power transmission shaft such that torque can be transmitted between the two. The attaching and detaching mechanism has a cylindrical member that fits over the power transmission shaft, a retaining ring that is radially movable, and an annular member that is axially movable. By using a boot band to fixedly tighten, to the power transmission shaft, a small diameter end portion of a boot closing an opening portion of the outer joint member, the axial position of the annular member is restricted by the small diameter end portion.

A quick disconnect system includes a main shaft, a sprocket shaft mounted around the main shaft, a coupler configured to move relative to the main shaft and the sprocket shaft between a connected configuration wherein the coupler is configured to connect the main shaft to the sprocket shaft such that torque is transferred between the main shaft and the sprocket shaft, and a disconnected configuration wherein the main shaft is configured to rotate relative to the sprocket shaft, and a release button configured to be actuated to release the coupler from the connected configuration or the disconnected configuration.

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 universal joint assembly includes a yoke including a serration hole to receive an end portion of a steering column and a bolt-hole to receive a bolt which is used to restrict the steering column received in the serration hole, and a misassembly prevention member coupled to the yoke and elastically movable from a first position in which the bolt-hole is at least partially blocked to a second position in which the bolt-hole is opened, thereby preventing a misassembly of the steering column and improving safety and reliability of the universal joint assembly.

A torque transmitting assembly including a first drum having a plurality of teeth formed at an end thereof and a sensor component annularly extending on an inner surface of the first drum. A gear assembly axially aligns with the first drum and has a plurality of teeth intermeshing with the plurality of teeth of the drum. The gear assembly includes an annular gear and a plate axially aligning with the gear.

A joint assembly includes a first member having splines formed therein. A second member includes splines formed thereon and is coupled to the first member. The splines of the first member engage the splines of the second member. An access window is formed on the first member. A ring retains the first member to the second member. A seal extends across a joint between the first member and the second member and covers the access window. A portion of the ring is accessible through the access window following removal of the seal, where the ring can be manipulated to release the first member from the second member.
