Definitions
- the present invention relates to a fluid coupling.
- the fluid coupling has an impeller and a turbine inside, and transmits torque via the internal hydraulic oil.
- the impeller is fixed to a front cover to which torque from the engine is input.
- the turbine is disposed opposite the impeller in the fluid chamber. When the impeller rotates, hydraulic oil flows from the impeller to the turbine, and torque is output by rotating the turbine.
- the lock-up device is arranged between the turbine and the front cover.
- the lockup device mechanically couples the turbine and the front cover to transmit torque directly from the front cover to the turbine.
- the torque converter disclosed in Patent Document 1 omits the installation of a lock-up device in order to reduce its size. As a result, the torque converter can be reduced in its axial dimension.
- the torque converter of Patent Document 1 described above has a turbine that is movable in the axial direction instead of omitting the lock-up device.
- the torque converter has a friction material between the turbine and the impeller so that the turbine and the impeller are frictionally engaged.

- the connecting portion is formed integrally with the piston and the turbine shell.
- the clutch is a friction material attached to the piston.
- the fluid coupling according to the present invention can be made compact without changing the supply direction of the working fluid at the time of lock-up.
