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.

Marine propulsion apparatus

An axle driving apparatus may include a first rotary shaft connected to an internal combustion engine; a second connected to an electric motor; a third rotary shaft connected to a driving shaft of a wheel; an interlocking unit interlocking the first, second, and third rotary shaft; and an input and output switchover unit. The interlocking unit and the input and output switchover unit are structured to switch the interlocking unit between a first mode in which only the power of the internal combustion engine is output from the third rotary shaft, a second mode in which only the power of the electric motor is output from the third rotary shaft, a third mode in which the power of the internal combustion engine and the power of the electric motor are combined and output from the third rotary shaft, and a fourth mode in which the power of the internal combustion engine is output from the second rotary shaft to the electric motor.

Axle driving apparatus for hybrid utility vehicle

A riding type vehicle has a driving source, a left wheel and a right wheel, a transmission configured to receive power from the driving source to independently operate and drive the left wheel and the right wheel with regard to a rotation direction and a rotation speed, and caster wheels separately provided in a front-rear direction with respect to the left wheel and the right wheel, the riding type vehicle including two first sensors arranged on both left and right sides more to a front side than a rear end of the vehicle, the two first sensors configured to detect an obstacle target located on a rear side, the obstacle target being a target becoming an obstacle at the time of reversing or turning.

Riding type vehicle

A transaxle comprises a hydrostatic transmission (HST), an axle, a gear train interposed between the HST and the axle, a casing and a partition. The casing defines an HST chamber and a gear chamber. The HST is disposed in the HST chamber. The gear train and the axle are disposed in the gear chamber. The partition is disposed in the casing so as to separate the HST chamber and the gear chamber from each other. The partition has an opening through which a hydraulic motor of the HST passes to extend from the HST chamber into the gear chamber so as to be drivingly connected to the gear train. The partition obstructs a flow of fluid between a fluid sump in the HST chamber from a fluid sump in the gear chamber.
