Abstract
The present invention relates to a torque converter that may reduce production cost by a simple structure compared to the conventional art, reduce the overall size of the torque converter by minimizing an installation space of an anti-resonance damper, and improve damping performance.
Claims15
A torque converter includes:
- a front cover connected to an output side of an engine;
- an impeller connected to the front cover and integrally rotated with the front cover;
- a turbine provided with a turbine blade receiving torque from the impeller through a fluid and a turbine shell supporting the turbine blade;
- a lock-up device disposed between the front cover and the turbine;
- a damper assembly connected to the lock-up device;
- and
- an output hub connected to the damper assembly and transmitting the torque to the outside,
- wherein the damper assembly comprises:
- an input member to which the torque is input from the lock-up device;
- an output member that is relatively rotatably while connected to the input member and is non-rotatably connected to the output hub;
- a first damper spring and a second damper spring elastically connecting the input member and the output member with respect to a rotating direction;
- an intermediate member that is relatively rotatably connected to the input member through the first damper spring and that is relatively rotatably connected the output member through the second damper spring;
- and
- an anti-resonance damper installed directly on the intermediate member,
- wherein the anti-resonance damper is disposed outside a radial direction with respect to the first damper spring and the second damper spring.
