  • Publication number: 20230043913
    Abstract: The present invention provides a hybrid driving module which fixes a rotor while hub ridges of the rotor are provided on a rotor hub and firmly provides the hub ridge to the rotor hub so as to enable vibration noise to be reduced, and which has a structure in which the hub ridges support the rotor in a state in which the hub ridges are fastened to the rotor hub at which the rotor is provided. The hybrid driving module may further include a ridge fixing structure that prevents the hub ridge from separating from the rotor hub. For example, the ridge fixing structure may be a ridge snap ring. The hybrid driving module may further include an elastic body that elastically presses the hub ridge toward the ridge snap ring. The elastic body may elastically press the rotor in the axial direction. The elastic body may also serve as a return spring of the piston plate of the engine clutch.
