Abstract
The invention relates to a plunging assembly for a driveshaft, especially for being used in the driveline of a motor vehicle. The plunging assembly comprises a tubular outer joint part ( ) with a longitudinal axis and circumferentially distributed outer running grooves ( ) extending parallel to the longitudinal axis; an inner part ( ) with inner running grooves ( ) extending parallel to the longitudinal axis, as well as a plunging unit ( ) with a cage ( ) and balls ( ) provided for torque transmitting purposes. Furthermore, there are provided means for delimiting the path which can be covered by the inner part ( ) relative to the outer part ( ) during the moving-in and moving-out motion. The means being arranged between the inner part ( ) and the plunging unit ( ) as well as between the plunging unit ( ) and the outer part ( ). The length of the inner running grooves ( ) differs from that of the outer running grooves ( ). This design ensures that a rolling and a sliding movement during the moving-in and moving-out motion is delimited without the balls ( ) of the cage ( ) being jammed and without the plunging unit being locked.
