Abstract
A torque converter 1 equipped with a lockup device 8 is provided to secure sufficient space in the axial direction for the damper in a hydraulic torque transmitting device provided with a lockup device having a damper. Lockup device 8 is disposed between a front cover 4 and a turbine 6. Lockup device 8 has a clutch mechanism 31 for mechanically coupling front cover 4 and turbine 6 and a damper mechanism 32 for absorbing and attenuating torsional vibrations. In the vicinity of its outlet, turbine 6 has a linearly shaped part 62 that is aligned with damper mechanism 32. As a result, the axial dimensions of torsion springs 52 can be enlarged.
Claims10
A hydraulic torque transmitting device that uses a fluid to transmit torque, said hydraulic torque transmitting device comprising:
- a front cover configured to receive an input torque;
- a torus including an impeller that forms a fluid working chamber with said front cover, and a turbine disposed opposite to said impeller within said fluid working chamber;
- and
- a lockup device disposed between said front cover and said turbine, and said lockup device including a clutch part arranged to mechanically couple said front cover with said turbine, and a damper part arranged to attenuate torsional vibration,
- said turbine being configured with a linearly shaped part that is axially aligned with said damper part in the vicinity of an outlet.
