An engine clutch motor coupling structure for a hybrid transmission for coupling a retainer of the engine clutch with a rotor of a motor in the hybrid transmission, the motor coupling structure comprising:
- at least one damping unit installed in an axial direction of the rotor in the retainer between an end of the rotor and the retainer, and connected with the end of the rotor;
- wherein the end of the rotor includes a plurality of crowns protruding therefrom, and an edge portion of the retainer includes a plurality of radial protrusions being inserted among the crowns, and
- the at least one damping unit is coupled with the plurality of radial protrusions in the axial direction of the rotor and connected with an axial restraint among the crowns;
- wherein the at least one damping unit comprises:
- a washer coupled with a mounting hole formed in one of the plurality of radial protrusions in the axial direction of the rotor, and
- a coupling pin fitted in the washer and axially coupled with the axial restraint;
- and
- wherein the plurality of crowns are provided with a snap ring for supporting an axial compression repulsive force of the washer.
An engine clutch motor coupling structure for a hybrid transmission for coupling a retainer of the engine clutch with a rotor of a motor in the hybrid transmission, the motor coupling structure comprising:
- a plurality of crowns protruding along an axial direction of at the end of the rotor and spaced along a circumferential edge of the rotor;
- a plurality of radial protrusions extending from an edge portion of the retainer along a circumferential edge and inserted among the crowns;
- a washer coupled with a mounting hole formed in at least one radial protrusion in the axial direction of the rotor;
- and
- a coupling pin fitted into the washer and axially coupled with an axial restraint among the crowns;
- wherein the washer comprises;
- a washer body fitted into the mounting hole,
- a first flange integrally formed on one side of the washer body and supporting one surface of one of the plurality of radial protrusions, and
- a second flange integrally formed on the other side of the washer body and supporting an opposing surface of one of the plurality of radial protrusions and the axial restraint.
