Abstract
A hybrid driving module includes a rotor with a hub ridge provided on a rotor hub to enable vibration noise to be reduced, and the hub ridge supports the rotor in a state in which the hub ridge is fastened to the rotor hub. 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.
Claims10
A hybrid driving module comprising:
- a motor comprising a stator and a rotor;
- a rotor hub configured to support the rotor and rotate integrally with the rotor;
- and
- a hub ridge coupled to the rotor hub so that a rotation thereof is restricted,
- wherein the rotor hub comprises a rotor holder configured to support the rotor,
- wherein the rotor holder comprises:
- a radial support portion extending in an axial direction and configured to support a radial inner portion of the rotor;
- an axial support portion disposed at one side of the radial support portion based on the axial direction, extending in a radial direction from the radial support portion, and configured to support one side of the rotor based on the axial direction;
- a plurality of spline shape portions provided at the other side of the radial support portion based on the axial direction and further extending to the other side in the axial direction from the other end of the radial support portion based on the axial direction;
- and
- a plurality of spline grooves provided between the plurality of spline shape portions and opened at the other side based on the axial direction, wherein the hub ridge comprises:
- a piston installation portion disposed at a radial inner side of the plurality of spline shape portions;
- and
- a hub coupling portion connected to a radial outer side of the piston installation portion, wherein the hub coupling portion comprises:
- a plurality of fitting portions, of which the rotations are restricted by the rotor hub by interfering with the plurality of spline shape portions in a circumferential direction in a state in which the plurality of fitting portions are respectively inserted into the plurality of spline grooves;
- a radius extension portion further extending radially outward from the fitting portions and further protruding outward in the radial direction than the radial support portion;
- and
- an accommodation groove provided between the plurality of fitting portions and configured to accommodate a spline shape portion of the plurality of spline shape portions, and
- wherein the radius extension portion supports the other side of the rotor based on the axial direction.
