  • Publication number: 20110092300
    Abstract: 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.

  • Publication number: 20110039627
    Abstract: A connecting arrangement between a shaft journal (2), which is mounted so as to be axially fixed with respect to a unit, and a joint part (10) which can be pivotably attached to the shaft journal in a rotationally fixed manner. A shaft nut (5) having an internal thread (6) which can be screwed onto an external thread (4) of the shaft journal, is provided with an additional external thread (8) onto which a further nut (12) can be screwed via a counter-thread (21) to produce an axially acting interlocking connection (13) between the further nut (12) and the joint part (10).

  • Publication number: 20100275429
    Abstract: 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.

  • Publication number: 20100218583
    Abstract: A transmission, particularly for a motor vehicle, having at least two torque transmitting shafts, shafts suitable for use in such a transmission, and a method for the production such shafts. At least one of the shafts is composed of a shaft base body (10) and at least one gearwheel (3a, 4a), which is at least substantially finished separately from the shaft and subsequently is fixed to the shaft in such a way as to transmit torque available at the shaft or input torque by the gearwheel having a hollow hub body (13, 14) and being axially pressed onto a seat (11, 12) on the shaft base body so as to form a frictional connection which transmits the torque from the shaft to the gearwheel.

  • Patent number: 7682257
    Abstract: A constant velocity joint having an inner hub and an outer hub (1) in which races or tracks (3) 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 (2) which, when the joint is assembled, is connected in a rotationally fixed manner to one of the hubs (1) by mating profile members (6, 7) in order to transmit torque.

  • Publication number: 20090317182
    Abstract: 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.
