Abstract
A motor connection structure may be configured for coupling a rotor of a motor and an engine clutch retainer in the hybrid transmission. An example motor connection structure includes a damping unit coupled to an outer circumferential surface of the retainer in an axial direction of the rotor on an inner side of the rotor and supporting each of (i) the outer circumferential surface of the retainer, (ii) an inner circumferential surface of the rotor, and (iii) a coupled portion of the retainer.

An engine clutch motor connection structure for a hybrid transmission, the motor connection configured for coupling a rotor of a motor and an engine clutch retainer in the hybrid transmission, the motor connection structure comprising:
- a damping unit coupled to an outer circumferential surface of the retainer on an inner side of the rotor;
- and supporting each of (i) the outer circumferential surface of the retainer, (ii) an inner circumferential surface of the rotor, and (iii) a coupled portion of the retainer;
- and
- a snap ring supporting an axial directional compression repulsive force of the damper positioned in the coupled portion of the rotor;
- wherein the damping unit includes a support ring inserted into the outer circumferential surface of the retainer and a damper provided in the support ring.
An engine clutch motor connection structure for a hybrid transmission, the motor connection configured for spline-coupling a rotor of a motor and an engine clutch retainer in the hybrid transmission, the motor connection structure comprising:
- a plurality of crown portions protruding from a coupled portion of the rotor in an axial direction of the rotor and spaced apart from each other in a circumferential direction;
- a plurality of radial protrusions protruding from a coupled portion of the retainer in a radial direction and inserted between the plurality of crown portions;
- a support ring coupled to an outer circumferential surface of the retainer, and supporting the outer circumferential surface of the retainer and the plurality of radial protrusions;
- and
- a damper provided on the support ring and supporting an inner circumferential surface of the rotor.
