Tube for joining hollow shaft with cam or hub, has shaft end surface aligned with front surface of hub and front surface of head including seal to obtain pressure-resistant sealing connection under application of retention force

The tube (4) has a cylindrical tube base body displaceable in a hollow shaft (1) and a tube head (11) connected with the base body as a single piece. An axially running longitudinal channel (7) is attached to a pressurizing agent producer and pressurizing agent-guiding radial channels (8) connected with the channel for expansion of the shaft. A shaft end surface (6) is aligned with a front surface (3) of a hub (2), and a front surface (5) of the head including an annular seal (10) to obtain a pressure-resistant sealing connection under application of axially aligned retention force (FH). Die Erfindung betrifft eine Fügesonde zum Befestigen von Bauteilen, z.B. Nebenelementen nach dem Innenhochdruckfügeverfahren. Durch die vorgeschlagene Fügesondengeometrie mit axialer Abdichtung des Fügebereiches gelingt es, Nabenelemente ohne zusätzlichen Wellenüberstand auf einer Seite der Sonde zu fügen.
