Title:
TORQUE CONVERTER FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2014/084458
Kind Code:
A1
Abstract:
Disclosed is a torque converter, comprising a torsional damper, for reducing natural frequency and improving a vibration isolation function by absorbing vibration energy from anti-resonance. The torque converter according to the present invention comprises the torsional damper, wherein the torsional damper comprises a retaining plate coupled to a piston, a plurality of springs which are arranged on the retaining plate and through which elastic force acts in the circumferential direction, a driven plate which is operated with reaction force with respect to the springs and is coupled to a spline hub that delivers driving force to a transmission, and an inertial lever provided with a fixed pivot coupling portion which is arranged between the piston and the driven plate and is coupled to the piston by means of a fixed pivot, and a movable pivot coupling portion which is coupled to the driven plate by means of a movable pivot.
