A method and a device for fracture splitting a connecting rod and a connecting rod formed therefrom are provided, in which a force exerted on an outer rim of an eye of the connecting rod by a separating tool is generated by an electromagnetic force. The separating tool includes at least two separating members inserted into the eye, and the electromagnetic force is generated by displacing the at least two separating members away from each other inside the eye in response to application of the electromagnetic force. The electromagnetic force may be generated by passing current through coils positioned between the at least two separating members in a manner that causes the coils to repel one another, preferably with a pulse duration of less than 100 microseconds, in order to minimize plastic deformation at the fracture locations.

Method for fracture splitting a connecting rod and corresponding device

A method for producing an internal or external part of a torque-transmitting opposed track joint, such as a fixed constant velocity ball joint, in which approximately axially parallel extending track bases of the joint tracks have curvatures which deviate in their axial course from the curvatures of the ball contact lines. The method is characterized in that in a first step a perform with approximately axially parallel extending grooves having lateral flanks is produced, and in a second step the perform is formed into a final joint part whereby the lateral flanks of the grooves are just partially formed to achieve the ball contact lines.

Method for producing an internal or external part of an opposed track joint

A cage for a ball joint, the cage being configured annularly about a longitudinal axis and having an inner surface and an outer surface, two edges delimiting the inner surface and the outer surface and a window, in which the inner surface surrounds an inner space of the cage and two webs laterally adjoin the window. One edge of the cage has an offset relative to the longitudinal axis in relation to one of the two webs at the height of the window. A ball joint with a corresponding cage is also disclosed.

Cage for ball joint and ball joint

An axle assembly comprising a differential provided with a drive wheel comprising two pairs of bevel gears disposed in a two-part housing, one of the pairs of bevel gears being a pair of axle bevel gears and the other pair of bevel gears being a pair of compensating bevel gears.

Axle assembly with a differential provided with a drive wheel

A method for producing a torque transmission device such as a fixed constant velocity ball joint constructed as an opposed track joint in which the curvatures bases of the tracks of the joint deviate in their axial course from the curvatures of the ball contact lines. The method is characterized in that prior to the formation of a longitudinal profile of a joint component, the component is brought to an increased hardness by a hardening process and a diffusion layer is partially or completely removed in the region of the longitudinal profile.

Method for producing a torque transmission device useful as a fixed constant velocity ball joint for drive shafts

A connecting arrangement between a shaft journal and a constant velocity rotary joint having a joint inner part and a joint outer part, in which the shaft journal engages in a rotationally fixed manner in one of the joint parts, and the shaft journal and the constant velocity rotary joint are two components. At least one clamping sleeve is provided which is axially secured on one of the components, and which includes at least one elastic element which can lock in place in a contour of the other component.

Connecting arrangement between shaft journal and constant velocity rotary joint

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

The invention relates to a connecting arrangement between a shaft end and a joint part in which a collar on a connecting nut engages behind a another collar on the shaft end or on the joint part or on a clamping nut which clamps a bearing on the shaft, and one of the collars is formed by a oval ring received in a groove which facilitates disassembly of the connection formed by the connecting arrangement.

Connecting arrangement

A differential provided with a drive wheel comprising two pairs of bevel gears disposed in a two-part housing, one of the pairs of bevel gears being a pair of axle bevel gears and the other pair of bevel gears being a pair of compensating bevel gears.

Differential provided with a drive wheel

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 connecting arrangement between a shaft journal, which is mounted so as to be axially fixed with respect to a unit, and a joint part which can be pivotably attached to the shaft journal in a rotationally fixed manner. A shaft nut having an internal thread which can be screwed onto an external thread of the shaft journal, is provided with an additional external thread onto which a further nut can be screwed. The further nut includes first and second thread sections with different pitch directions which produce an axially acting interlocking connection between the further nut, the shaft nut and the joint part.

A torque transmission device such as a fixed constant velocity ball joint constructed as an opposed track joint and a process for producing such a device, in which the curvatures bases of the tracks of the joint deviate in their axial course from the curvatures of the ball contact lines. The process is characterized in that prior to the formation of a longitudinal profile of the joint component, the component is brought to an increased hardness by a hardening process and a diffusion layer is partially or completely removed in the region of the longitudinal profile.

A connecting arrangement between a shaft journal (), which is mounted so as to be axially fixed with respect to a unit, and a joint part () which can be pivotably attached to the shaft journal in a rotationally fixed manner. A shaft nut () having an internal thread () which can be screwed onto an external thread () of the shaft journal, is provided with an additional external thread () onto which a further nut () can be screwed via a counter-thread () to produce an axially acting interlocking connection () between the further nut () and the joint part ().

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.
