Abstract: PURPOSE: A torsional damper of a vehicle clutch is provided to improve vibration at a low torque area by reducing a rattle and an abnormal vibration in an idle state. CONSTITUTION: A damper spring(30,32,34,36) comprises a free damper spring(48,50,52,54) with a large diameter and a main damper spring(56,58,60,62) with a small diameter which is inserted into the inner diameter unit of the free damper spring. The main damper spring with different free length absorbs the torsional vibration with multi-step intensity by gradually changing the damper intensity.

Abstract: PURPOSE: A torque convertor of an auto transmission for the vehicle is provided to implement high displacement - high attenuation by increasing the resistance of an oil inflow into a damping force. CONSTITUTION: An oil damper is formed between a drive plate(20) and a turbine. The drive plate forms a damper clutch. The oil damper has a certain distance to the outside of a turbine and has equal interval in a columnar direction. The oil damper comprises a damper housing and a piston. The piston is assembled with a drive plate to be one body and is slidable left and right in the damper housing. The damper housing forms a closed space and has a plurality of orifices on inside and outside.
Abstract translation: 目的：提供用于车辆的自动变速器的扭矩转换器，以通过增加油流入阻尼力的阻力来实现高位移 - 高衰减。 构成：在驱动板（20）和涡轮机之间形成油阻尼器。 驱动板形成阻尼离合器。 油阻尼器与涡轮机外部有一定的距离，在柱状方向上具有相等的间隔。 油阻尼器包括阻尼器壳体和活塞。 活塞与驱动板组装成一体，并可在阻尼器壳体中左右滑动。 阻尼器壳体形成封闭空间并且在内部和外部具有多个孔。
