摘要： 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.

摘要： A connecting device for the connection of mechanical shaft parts, having a first connector section for connection to a first shaft part, and a second connector section for connection to a second shaft part, wherein the first connector section can be connected in a positively locking manner to a mating section of the first shaft part for the transmission of torque, wherein a locking mechanism which may be functionally independent of the transmission of torque is provided on the connecting device, said locking mechanism having at least one displaceable blocking element, for example a ball, which can be transferred between a release position, in which the first connector section can be released from the mating section, and a blocking position, in which a release of the mating section from the first connector section is prevented in a positively locking manner by way of the blocking element, wherein the locking mechanism has at least one displaceable locking bolt which, in a fixing position, secures the blocking element in the blocking position and, in a release position, permits a transfer of the blocking element into the release position, and which can be connected to an annular actuating element.

摘要： A propeller shaft for a vehicle in which a tube yoke is connected to a main tube via an adapter and tapered splines are formed at the contact regions between a tube yoke and the main tube to transmit the power output from a transmission to a rear wheel. The tube yoke and the main tube are displaced relative to each other at the tapered splines to break the adapter. The tube yoke and the main tube are thus separated from each other by virtue of the breakage of the adapter.

摘要： A shaft coupling includes a first shaft supported by a bearing at a first end, and a second shaft supported by a bearing at a second end. The first shaft and second shaft are coaxially arranged so that the second end of the first shaft is against the first end of the second shaft. On an end surface of the second end of the first shaft, there is a recess, and a protrusion protrudes from the end surface of the first end of the second shaft, and the recess receives the protrusion. The shaft coupling includes only one third bearing, as well as a coupler which receives the second end of the first shaft and the first end of the second shaft. With such a solution, a greater radial error may be allowed between the shafts without the structures of the coupling point being overloaded.

摘要： A gear-tooth system can be produced on a component of a shaft/hub connection. The component can have a first axis of rotation and a gear-tooth system; wherein the gear-tooth system of the component comprises a plurality of teeth, disposed next to one another along a circumference direction, wherein a tooth interstice is disposed between two teeth, in each instance, and each tooth has a head region and a flank region, in each instance, between head region and a foot region disposed in the tooth interstice, wherein the tooth interstice has a tooth gap width in the flank region; wherein the gear-tooth system has at least a first region and subsequently a second region along an axial direction parallel to the first axis of rotation; wherein the first region has a first tooth gap width and the second region has a second tooth gap width, which is less in comparison.

摘要： A constant velocity ball joint uses a star shaped sleeve with a splined connection to its shaft. The sleeve is longitudinally retained on its shaft using a retaining ring in an outwardly facing groove of the shaft. The star shaped sleeve has a 30° assembly assist chamfer angle on one side, as well as a 45° transition chamfer angle and a 65° ramp chamfer angle facing the opposite direction. These angles control the diameter of the retaining ring as it is compressed inward into the groove during assembly and disassembly. The star shaped sleeve can be used in a dynamic length CV joint, with the splines of a configuration that allows longitudinal sliding of the sleeve on the shaft, so the shell of the dynamic length CV joint still can be of the spherical race type.

摘要： A constant velocity universal joint includes an outer joint member and an inner joint member between which torque is transferred through intermediation of balls while allowing angular displacement. A power transmission shaft is coupled to the inner joint member to allow torque transmission therebetween. 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, a snap ring mounted inside the tubular member, a pushing member arranged on a radially outer side of the snap ring to be movable in a radial direction, and an annular member arranged on an outer peripheral surface of the tubular member to be movable in an axial direction.

摘要： A propeller shaft assembly comprises a first rotary component having a first splined portion and a first engaging surface arranged transverse to a longitudinal axis of the first rotary component and spaced from the first splined portion and a second rotary component having a second splined portion configured to engage the first splined portion. The second splined portion defines a second engaging surface arranged transverse to the longitudinal axis of the first rotary component. A shear component is disposed between the first engaging surface of the first rotary component and the second engaging surface of the second rotary component. The shear component forms a crash feature of the propeller shaft assembly configured to shear at an edge of the second engaging surface when the first shear component is compressed between the first engaging surface and the second engaging surface.
