  • Patent number: 8771143
    Abstract: In a hybrid power system, when a change-speed stage selected in one of gear-shift mechanisms for first and second drive trains is switched over to another change-speed stage in the other gear-shift mechanism, deceleration in rotation speed of an engine detected by a rotation speed sensor is compared with a preset upper limit. When the deceleration in rotation speed of the engine exceeds the upper limit, the motor-generator in drive connection with an input shaft of the second drive train is activated as an electric motor to cause load torque canceling or offsetting input torque applied to the input shaft of the other gear-shift mechanism from the engine, and engagement of the change-speed stage in the other gear-shift mechanism is released after the occurrence of the load torque.

  • Patent number: 8659192
    Abstract: A rotary electrical apparatus includes a housing, a stator including a center axis inclined by a predetermined angle relative to a horizontal direction in a case where the housing is fixed to a mounting member, a rotor, and an oil stored at a lower side within the housing relative to the center axis and functioning as at least one of a cooling oil, a lubricating oil, and an operating oil. The housing includes an oil inlet port and an oil discharge port allowing the oil to be discharged once a predetermined amount of the oil is stored within the housing, the oil discharge port being displaced from a first oil passage on which the oil supplied from the oil inlet port moves downward along an inner peripheral wall surface of the housing in a state where the housing is held so that the center axis is arranged to be horizontal.
