  • Patent number: 8070376
    Abstract: 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 T1 of 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 T2 of the insertion path E.

  • Patent number: 8057313
    Abstract: A longitudinal shaft, for use in particular in four-wheel drive or rear-wheel drive motor vehicles includes a gearbox-side articulation, a differential-side articulation, as well as a central articulation through which a gearbox-side section is integrally linked in rotation to a differential-side section of the longitudinal shaft. To reduce the centrifugal forces occurring at the longitudinal shaft in operation. Therefore, the gearbox-side articulation and the differential-side articulation have each an inner hub, designed to connect the longitudinal shaft integrally in rotation respectively to a gearbox output shaft and to a differential input shaft, the longitudinal shaft being centered on the gearbox output shaft and the differential input shaft by interlocking through the inner hubs.

  • Patent number: 7972218
    Abstract: 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.

  • Patent number: 7867098
    Abstract: A ball-and-socket joint comprising an inner hub (1) and an outer hub (6) inside which tracks are disposed that are associated with each other in pairs. At least one ball is arranged in each track in order to transmit torque between the inner hub and the outer hub. The ball-and-socket joint further includes at least one diaphragm which seals the outer hub with respect to a joining element that can be connected in a torsion-proof manner to the inner hub. The outer hub is provided with a metallic interior element encompassing the tracks, a dampening element which embraces the interior element in at least some areas, and a cap that embraces the damping element in at least some areas in order to connect the outer hub to a driving part or a part to be driven. The damping element is made of a material having a modulus of elasticity lower than the modulus of elasticity of the metallic material of the interior element and/or the cap of the outer hub while being greater than the modulus of elasticity of the diaphragm.
