  • Patent number: 11541749
    Abstract: A moving body drive unit has an electric motor that is located inside the case and has a motor shaft extending in a first direction, a gear shaft that is located, inside the case, parallel to the motor shaft so as to extend in the first direction and has a bevel gear formed thereon, an intermediate gear mechanism that transmits power from the motor shaft to the gear shaft, and a differential gear device that is located inside the case and has a ring gear that meshes with the bevel gear to transmit power from the gear shaft to two output shafts extending in a second direction. The motor shaft and the gear shaft are arranged at different positions in both the second direction and in a third direction that is orthogonal to both the first direction and the second direction.

  • Publication number: 20220289355
    Abstract: In a marine propulsion apparatus that transmits power of at least one of an internal combustion engine (ICE) and a generator motor (GM) mounted on a ship to a propeller via a forward reverse switching mechanism, the marine propulsion apparatus can be downsized as a whole. The marine propulsion apparatus includes a connection switching mechanism capable of selectively connecting the GM to an upstream side and a downstream side of the power transmission from the ICE in the forward reverse switching mechanism. Then, the forward reverse switching mechanism is interposed between the ICE and the connection switching mechanism, and a large torque from the ICE is not directly transmitted to the connection switching mechanism. As a result, it is not necessary to increase the capacity of the connection switching mechanism, and the connection switching mechanism and thus the marine propulsion apparatus can be downsized.
