  • Patent number: 11858327
    Abstract: A vehicle drive device includes a rotary electric machine disposed on a first axis, an output member disposed on a second axis parallel to the first axis, an inverter device, a terminal block for electrically connecting a rotary electric machine-side bus bar and an inverter-side bus bar, and a case. The case includes a first housing chamber for housing the rotary electric machine MG, a second housing chamber for housing the inverter device, and a partition wall for separating the first housing chamber and the second housing chamber. A terminal block is disposed such that an arrangement area of the terminal block in an axial direction overlaps the rotary electric machine, and disposed so as to penetrate the partition wall in a radial direction of the output member.

  • Patent number: 11065957
    Abstract: The drive power connecting/disconnecting device includes a second shaft disposed coaxially to a first shaft so as to transmit drive power to a wheel axle, a connection/disconnection member which moves a second rotational body along an axial direction with respect to a first rotational body, and which is capable of moving in the axial direction so as to make or break engagement between the first shaft and the second shaft, a supporting member, a shaft cover which covers at least the periphery of the second rotational body, a first pivotally supporting portion which is disposed between the first shaft and the second shaft so as to axially support one end of the second shaft; and a second pivotally supporting portion which is disposed inside the shaft cover so as to axially support the other end of the second shaft.

  • Patent number: 9046156
    Abstract: A hybrid drive device includes: a gear mechanism that divides and transmits rotary power of an internal-combustion engine to first motor generator and second motor generator; a first shaft to which rotary power of the first motor generator is transmitted; a rotary element; a second shaft to which rotary power of the rotary element is transmitted after deceleration; a third shaft to which rotary power of the second shaft is transmitted after deceleration; a first power-transmission switching mechanism that can switch rotary power of the second motor generator among a state of being transmitted to the rotary element, a state of being transmitted to the third shaft, and a state of not being transmitted; and a second power-transmission switching mechanism that can switch rotary power of the first shaft between a state of transmission to the second shaft and a state of not transmitted.
