Abstract
A torque converter disposed between a prime mover and an output shaft is disclosed. The torque converter includes a cover, an impeller, a turbine, and a first clutch. The impeller is unitarily rotated with the cover. The turbine is disposed opposite to the impeller. The first clutch is configured to allow and block transmitting power outputted from the prime mover to the cover.
Claims5
A torque converter disposed between an electric motor and an input shaft of a power transmission device, the torque converter comprising:
- a cover;
- an impeller unitarily rotated with the cover;
- a turbine disposed opposite to the impeller;
- a first clutch configured to allow and block transmitting power outputted from the electric motor to the cover;
- a second clutch directly coupled to the input shaft to allow and block transmitting the power outputted from the electric motor directly to the input shaft without the power flowing through either of the cover or the turbine;
- and
- a third clutch, the third clutch being a one-way clutch configured to allow transmitting the power from the turbine to the input shaft and to block transmitting the power from the input shaft to the turbine;
- wherein when a rotational speed of the electric motor exceeds a predetermined value, the first clutch is switched from allowing transmitting the power to blocking transmitting the power, and the second clutch is switched from blocking transmitting the power to allowing transmitting the power.
