摘要： The present invention relates to a hybrid drive module, which may ensure pressing pressure for a lock-up clutch while reducing, through a simple structure, operating pressure of a piston for pressing a lock-up clutch disposed in a space to which fluid pressure of a torque converter is applied, the hybrid drive module having a small number of components and being capable of being easily assembled. The present invention is accomplished by providing a compensation chamber of the piston and filling the compensation chamber with a low-pressure fluid. In addition, the low-pressure fluid may be used as a fluid for lubricating and cooling an engine clutch.

摘要： The present invention provides a lock-up clutch for a torque converter. The lock-up clutch includes an outer carrier, an inner carrier, a first friction plate, a rotation of which is restricted by the outer carrier, and a second friction plate, a rotation of which is restricted by the inner carrier. All key grooves of the outer and inner carriers are opened in two radial opposite directions, and flow path grooves defined between friction members attached to the friction plate are aligned with circumferential positions of keys of the friction plate. Therefore, oil for cooling a clutch pack may smoothly flow through the inner carrier, the flow path grooves, and the outer carrier.

摘要： The present invention provides a hybrid driving module which fixes a rotor while hub ridges of the rotor are provided on a rotor hub and firmly provides the hub ridge to the rotor hub so as to enable vibration noise to be reduced, and which has a structure in which the hub ridges support the rotor in a state in which the hub ridges are fastened to the rotor hub at which the rotor is provided. 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.

摘要： Damper apparatus for use with vehicle torque converters are disclosed. A disclosed damper assembly for a vehicle torque converter includes a first portion operatively coupled to a clutch of the vehicle torque converter and configured to receive an engine torque from the clutch based on a state of the clutch. The damper assembly also includes a second portion and a hub rotatably coupled to a turbine of the vehicle torque converter. The damper assembly also includes a gear train including a ring gear coupled to the first portion, a planet gear rotatably coupled to the second portion, and a sun gear coupled to the hub. The damper assembly also includes a primary damping element positioned in a cavity formed by the second portion. Rotation of the first portion relative to the second portion compresses and decompresses the primary damping element to dampen a torsional vibration associated with the engine torque.
