  • Power transmission device
    Patent number: 11207966
    Abstract: A power transmission device outputting torque from a first power source and a second power source to axles, is provided with: a first shaft coupled with the first power source; a differential configured to differentially distribute the torque to the axles; a first gear set configured to drivingly couple the first shaft with the differential; a second shaft coupled with the second power source; a second gear set drivingly coupled with the second shaft; a clutch configured to receive fluid pressure to drivingly and releasably couple the second gear set with the first gear set; and a pump driven by a third power source at least independent of the first power source and the clutch to generate the fluid pressure, the pump being disposed separate from the clutch and in fluid connection with the clutch to supply the fluid pressure.
    Type: Grant
