  • Method for producing a shaft-hub connection, and motor vehicle shaft having such a connection
    Patent number: 11525482
    Abstract: A method for producing a shaft-hub connection in which a shaft component and a hub component are placed into a joined state in the form of a frictional shaft-hub connection. The shaft component has a toothed region having teeth with a height H, and the hub component has a mating toothed region having a mating region internal diameter d. The hub component is pushed onto the shaft component in a longitudinal direction to produce the frictional shaft-hub connection and in the process geometrically reproduces the toothed region in the mating toothed region. The mating toothed region passes over a cylindrical centering region with an outer diameter D before coming into contact with the toothed region. The outer diameter D is at most 0.2 mm and at least 0.005 mm smaller than the mating region inner diameter d. The centering region has a length L greater than 1 mm.
