Abstract: A multi-part longitudinal drive shaft of a motor vehicle consists of two shaft sections that are each formed by a shaft tube connected with each other by a homokinetic displacement joint. The outer diameter of the shaft tube in the second shaft section is smaller than the inner diameter of the shaft tube of the first section. The outer joint ring of the homokinetic displacement joint is firmly connected with the shaft tube of the first shaft section and a ball hub of the joint is connected with the second shaft section. When a specific axial position is exceeded, the homokinetic displacement joint can be broken down. The individual parts of the two shaft sections can be displaced into one another, after break-down of the homokinetic displacement joint, so that the second shaft section is displaced in the direction of the first shaft section.

Abstract: A sealing assembly includes a sealing element and its placement in homokinetic joints. This sealing element seals the outer joint part relative to a pipe or a hollow shaft. The sealing element is connected with the outer joint part which is connected with a sealing rolled bellows on the opposite side. In this case, the sealing element is configured as a closure lid provided with a pressed projection, and a set back piece on its outer circumference. This lid includes a cylindrical or turned over shape, and is disposed on the outer joint part of the homokinetic joint by way of the pressed projection and by secondary weld seams of a friction weld or magnetic arc weld that connects the outer joint part with a pipe. This connection is with a shape fit or a force fit whereby the closure lid in the set back partial piece is configured with a circumferential groove as well as with planned breakage points.

Abstract: A longitudinal drive shaft for motor vehicles, for transferring a torque, consists of two or more shaft sections which are connected with one another by way of an intermediate shaft or a journal. The intermediate shaft or the journal is the carrier of a center bearing and is connected to the shaft section by a homokinetic displacement joint rigidly disposed in a pipe. The parts of the center bearing and shaft sections that are displaced in a crash are configured to be smaller than the inside diameter of the pipe. The inside diameter of the outer joint ring is greater than the outside diameters of the roller bearing of the center bearing and of the pipe. The homokinetic displacement joint is sealed off with a sealing cap and a sealing bellows in the direction of the shaft section, and has a closure lid assigned to it.

Abstract: A homokinetic displacement joint for longitudinal shafts of motor vehicles, has an outer and inner joint body having ball raceways, a cage between the joint bodies, and balls provided in the individual pairs of ball raceways. The balls are guided in the cage and the ball raceways are provided in alternating sequence, alternately rising to the right and left, to form slanted, spatially arranged ball raceways in the assembled state of the joint bodies. The individual ball raceways possess a track slant angle ? 8 and an incline angle ?? 9 that are determined, relative to one another, by the ratio ?:??=5:3.

This connection is with a shape fit or a force fit whereby the closure lid in the set back partial piece is configured with a circumferential groove 16 as well as with planned breakage points.

Abstract: A sealing and securing element for a homokinetic joint between hollow longitudinal shafts is disposed in an interior of the longitudinal shaft in a region of a connection point of the longitudinal shaft to the homokinetic joint. The sealing and securing element includes a molded part and a closure lid. The molded part has an inner structure configured in a first stepped shape with two accommodation openings, a guide bevel in a direction of the homokinetic joint and a circumferential projection. The closure lid has an outer structure configured in a second stepped shape with two projections. The inner structure of the molded part is adapted to the outer structure of said closure lid and has a same coverage as the outer structure. The closure lid is pressed into an interior of the molded part and rests against the circumferential projection.
