Method for connecting differential cage with driving wheel of axle differential gear box in passenger car, involves performing training process with rotating load, where amplitudes of load lie below rated load torque during process

摘要

The method involves coating mating faces of a shaft component i.e. differential housing (200), and a hub component i.e. driving wheel (300), with a thin metal layer (410) before joining the faces to a shaft hub press connection (400). A training process is performed with an alternative rotating load after joining the mating faces to the press connection, where amplitudes of the rotating load lie below a rated load torque transmitted from the press connection during the training process. The shaft component is formed from a malleable cast iron material. An independent claim is also included for a structural unit for an axle differential gear box of a motor vehicle.
