Abstract
A torsional damper disposed between a rotor sleeve, which is configured to receive a rotational force of an engine, and a rotor hub, which is disposed rearward of the rotor sleeve, and configured to transmit the rotational force of the engine to the rotor hub, and a hybrid drive module to which the torsional damper is applied, includes: a first damper, and the first damper includes a first cover plate provided at a driving side and having a first stopper, a first stopper accommodation portion provided at a driven side and configured to accommodate the first stopper, and shield members configured to cover an opening of the first stopper accommodation portion to restrict a movement of a fluid in a radial direction through the first stopper accommodation portion.

A torsional damper, which is disposed between a rotor sleeve, which is configured to receive a rotational force of an engine, and a rotor hub, which is disposed rearward of the rotor sleeve, and configured to transmit the rotational force of the engine to the rotor hub, the torsional damper comprising:
- a first damper,
- wherein the first damper comprises:
- a first damper spring configured to absorb vibration of the rotational force of the engine;
- a first cover plate disposed between the first damper spring and the rotor sleeve and connected to the rotor sleeve;
- and
- a driven plate disposed between the first damper spring and the rotor hub and connected to the rotor hub,
- wherein the driven plate comprises a first stopper accommodation portion configured to penetrate a thickness of the driven plate,
- wherein the first cover plate comprises a first stopper accommodated in the first stopper accommodation portion, and
- wherein the first damper further comprises shield members configured to cover an opening of the first stopper accommodation portion to restrict a movement of a fluid in a radial direction through the first stopper accommodation portion.
A hybrid drive module comprising:
- a rotor sleeve configured to receive a rotational force of an engine;
- a rotor hub disposed rearward of the rotor sleeve;
- and
- a torsional damper disposed between the rotor sleeve and the rotor hub and configured to transmit the rotational force of the engine to the rotor hub,
- wherein the torsional damper includes a first damper,
- wherein the first damper comprises:
- a first damper spring configured to absorb vibration of the rotational force of the engine;
- a first cover plate disposed between the first damper spring and the rotor sleeve and connected to the rotor sleeve;
- and
- a driven plate disposed between the first damper spring and the rotor hub and connected to the rotor hub,
- wherein the driven plate comprises a first stopper accommodation portion configured to penetrate a thickness of the driven plate,
- wherein the first cover plate comprises a first stopper accommodated in the first stopper accommodation portion, and
- wherein the first damper further comprises shield members and configured to cover an opening of the first stopper accommodation portion to restrict a movement of a fluid in a radial direction through the first stopper accommodation portion.
