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.
