Abstract
A flywheel assembly 1 includes a flywheel 2, a flexible plate 3 and a dynamic damper 4 to reduce the noise of an engine during acceleration of the speed of the engine. The flexible plate 3 connects the flywheel 2 with a crankshaft 5 so as to be able to oscillate in a bending direction. The dynamic damper 4 includes a mass body 13, and a plate 14 which connects the mass body 13 with the flywheel 2 so as to be able to oscillate in a bending direction.
Claims13
A torque converter comprising:
- a torque converter main body having a front cover,
- a flexible plate with a first rigidity in a rotational direction and a second rigidity in an axial direction that is lower than said first rigidity, said flexible plate being attached to said front cover;
- and
- a dynamic damper including a mass body and an elastic body which connects said mass body with said torque converter main body to oscillate in an axial direction relative to said torque converter main body.
