Document Type and Number:
WIPO Patent Application WO/2023/096200
Kind Code:
A1
Abstract:
The present invention relates to: a torsional damper which is disposed between a rotor sleeve (23) for receiving a rotational force of an engine and a rotor hub (90) disposed behind the rotor sleeve (23) and transfers the rotational force of the engine to the rotor hub (90); and a hybrid driving module having same applied thereto. The torsional damper comprises a first damper (30) including: a first cover plate (31) provided on a driving side and having a first stopper (319); and a driven plate (35) provided on a driven side and having a first stopper reception part (355) for receiving the first stopper (319) therein. The first stopper reception part (355) has a groove shape and does thus not penetrate the driven plate (35), so that a fluid lubricating and cooling the torsional damper does not pass through the driven plate (35) through the first stopper reception part (355). The first stopper reception part (355) is provided in an inclined section of the driven plate (35). A second damper (50) is connected in series to the first damper (30), and a first fluid passage (358) along which a fluid can flow through the driven plate (35) is provided in the driven plate (35). The fluid having passed through the first fluid passage (358) is supplied to the second damper (50).
