Abstract: A coupling connection for a fiber reinforced synthetic resin pipe, especially for a driving or driven hollow shaft of a motor vehicle, wherein the fibrous synthetic resin pipe is non-rotatably connected with a coupling element arranged concentrically to the pipe. The coupling element includes peripheral teeth and is pressed onto the fiber reinforced synthetic resin pipe in such a way that the coupling element forms a shape-mating connection with the fiber reinforced synthetic resin pipe in a direction of rotation of the pipe.

Abstract: An installation for damping vibrations of a drive axle, especially of a rear axle, of motor vehicles, in which the driving pinion of the differential gear which meshingly engages with the spur bevel gear, is driven by way of a universal joint shaft and in which the output from the differential gear onto the axle half-shafts takes place by way of one synchronizing joint each; for purposes of changing the resonant frequency of the system, additional annular parts constructed of shell-shape are clamped onto that part of the synchronizing joint which is connected with the output of the differential gear.

Abstract: An elastic shaft coupling, especially a cardan shaft coupling for motor vehicles, which is equipped with a disk-shaped elastic base body, in which are arranged about the center axis of the base body an even number of connecting elements having parallel axes; of these connecting elements, successive ones are coordinated to opposite sides and are connected by way of at least one band loop that is supported on at least one of the respective connecting elements by way of an elastic intermediate member.

Abstract: An installation for damping vibrations in the drive connection of motor vehicles with the aid of a vibration absorber whose absorber mass is constructed as annular body and is connected with at least one driving part of the drive connection by means of an elastic member of rubber or analogous material; the connection between the transmission output shaft and the universal joint shaft is thereby split up from a vibrational point of view by an elastic coupling soft in the radial direction while the vibration absorber is coordinated to the input of the universal joint shaft.

Abstract: An installation for damping vibrations in the drive connection of vehicles, especially of motor vehicles, with the aid of a vibration damper whose vibrating mass is constructed as annular body and is connected with a driving part of the drive connection by means of an elastic body; the damper thereby serves for damping the torsional vibrations of the drive connection and also the bending vibrations of the drive shaft while the elastic body is delimited, on the one hand, by a cylinder surface and, on the other, by a polygonal surface.
