A connecting arrangement for a rotationally fixed connection of components in the drive train of a motor vehicle, comprising a shaft journal and a hub of an articulation, which has a central opening for receiving the shaft journal, wherein the shaft journal can be axially fixed in the hub, for example by a retaining ring. The invention further relates to an articulated shaft comprising such a connecting arrangement.

Connecting arrangement and articulated shaft comprising same

A connecting arrangement for connecting, for example, two components of a jointed shaft via a securing ring, and a jointed shaft including a connecting arrangement of this type.

Connecting arrangement and jointed shaft comprising the same

A displacement unit comprising a tubular outer part on an inner surface of which outer paths are provided. An inner part displaceable in the tubular outer part in axial direction, on whose exterior surface inner paths are provided and a plurality of balls guided in a cage, the balls respectively located in outer and inner paths that are associated with each other in pairs. The tubular outer part and/or the inner part provided with cage guide paths between at least some of the paths for axial guiding the cage. A quantity of the cage guide paths is smaller than the quantity of pairs of paths formed by the outer and inner paths. The cage may comprise a plurality of integral guide path protrusions that engage the cage guide paths.

Displacement unit and universal shaft comprising a displacement unit

A system for connecting a shaft () to a joint (), which system includes a shaft journal () that is connected to the shaft (), and a sleeve () that is connected to a hub of the joint (), the sleeve () having a shaft-side first opening section (), a joint-side second opening section (), and a first radial stop section (), and the shaft journal () having a shaft-side first shaft-journal section (), a joint-side second shaft-journal section (), and a second radial stop section () for delimiting the insertion path of the shaft journal () in the sleeve ().

Connecting system and constant velocity joint

A drive joint, particularly a fixed joint in the form of a counter-track joint, for establishing a connection between two components in the drive train of a motor vehicle. The joint is provided with joint parts such as an inner hub, an outer hub and a ball cage containing torque-transmitting balls as additional joint parts. The outer hub of the drive joint can be destroyed in the case of an accident. The invention also relates to a drive shaft comprising such a drive joint.

Drive joint and drive shaft

A rolling-sliding unit, particularly for a jointed shaft, including a profiled sleeve () having outer raceways on an interior surface thereof; a journal () which is displaceable in the profiled sleeve () and which has inner raceways on an exterior surface thereof, and balls () in the raceways between the profiled sleeve and the journal for transmitting torque. A cover is provided on the journal of the rolling-sliding unit and an elastic element is arranged between the profiled sleeve and the journal of the rolling-sliding unit. A jointed shaft comprising a rolling-sliding unit of the described type also is described.

Rolling-sliding unit and jointed shaft comprising the same

A jointed shaft with two shaft sections which are connected together in a rotationally fixed manner via a central shaft which is constructed as a constant velocity fixed joint. A constant velocity fixed joint is also arranged on the end of each of the shaft sections which is oriented away from the central joint. At least one roller displacement unit, which enables both shaft sections to be displaced in an axial manner in relation to each other, is also provided.

Joint shaft and roller displacement UNIT THEREFOR

A system for connecting a shaft to a joint, and a corresponding method are provided, wherein a shaft journal embodied on the end of the shaft that is to be connected to the joint can be inserted into a recess of a joint connection. The aim of the invention is to be able to pre-assemble and axially align the shaft and the recess in a simple manner. To this end, the shaft journal and the recess are adapted to each other in such a way that the shaft journal can be displaced in the recess in an essentially weak manner in a first section Tof the insertion path E, and a large amount of force is expended for the displacement of the shaft journal in the recess in a section Tof the insertion path E.

System for connecting a shaft to a joint

A homokinetic joint includes an outer hub having outer running tracks, an inner hub having inner running tracks, balls which are guided in pairs consisting of an outer running track and an inner running track and a cage having cage windows, in which the balls are accommodated. The homokinetic joint further includes a sleeve that is firmly connected with the inner hub and disposed coaxial to it and sealing means having an accommodation part that is connected with the outer hub so as to rotate with it. The sealing means have a sealing membrane firmly connected with the outer hub by means of an outer collar, and connected with the sleeve by means of an inner collar, forming a seal, and having a securing ring for fixing the inner collar in place on the sleeve. The sleeve has a circumferential annular groove, into which the sealing membrane engages with an inner annular bead that is formed on.

Drive shaft and constant velocity joint for it

A drive shaft, in particular a longitudinal shaft for a motor vehicle, includes at least one hollow shaft cross-section and at least one homocinetic joint whose external hub is connected to the hollow shaft cross-section. The homocinetic joint is sealed off from the hollow shaft section by a lid, the lid and the hollow shaft section being configured and disposed so that the inner hub of the homocinetic joint does not penetrate significantly into the hollow shaft section as a result of an axial force that act on it, such as an axial force resulting from an accident.

A homokinetic joint includes an inner hub and an outer hub, wherein several pathways are associated together in pairs, wherein balls which are guided in a cage are received in order to transmit torque between the inner hub and the outer hub. A sealing arrangement includes a set of bellows and seals the homokinetic joint. The radially outer edge of the set of bellows is coupled to the outer hub and/or to a carrier housing engaging therewith. The radially inner edge is secured in a stationary manner on the inner hub.

Homokinetic joint having a sealing arrangement

A constant velocity joint having an inner hub and an outer hub () in which races or tracks () associated with one another in pairs are provided and with balls received in respective pairs of races or tracks for transmitting torque. The constant velocity joint is further provided with at least one joint connector () which, when the joint is assembled, is connected in a rotationally fixed manner to one of the hubs () by mating profile members () in order to transmit torque.

Constant velocity joint

A displacement unit and a jointed shaft which includes such a displacement unit. The displacement unit is formed of an external part and of an internal part which can be displaced in an axial direction in the external part, in which the external and internal parts have guide paths provided with balls arranged in the guide paths for the transmission of torque.
