A powertrain system for driving a vehicle comprises an engine, a transaxle including a hydraulic motor, a hydraulic pump separated from the hydraulic motor, and a gearbox joined to the hydraulic pump. The engine includes an engine output shaft extended in the lateral direction of the vehicle. The hydraulic pump and the hydraulic motor are fluidly connected to each other so as to constitute a hydrostatic transmission. The gearbox supports a PTO shaft. The gearbox incorporates gears for drivingly connecting the engine output shaft to the hydraulic pump, and for drivingly connecting the engine output shaft to the PTO shaft extended in the fore-and-aft direction of the vehicle.

An outboard motor includes an engine having an output portion. A lower gear mechanism drives a propeller disposed below the engine. A transmission includes an input shaft that transmits power from the output portion to the transmission. An output shaft transmits power from the transmission to the lower gear mechanism. A reverse idler shaft is parallel to an intermediate shaft. A forward clutch is disposed on one of the input and intermediate shafts and connects and disconnects power from the input shaft to the intermediate shaft. A reverse clutch is disposed on the intermediate shaft and connects and disconnects power transmission from the input shaft to the intermediate shaft. Power of the input shaft is transmitted to the output shaft via the forward clutch and the intermediate shaft and is transmitted to the output shaft via the reverse idler shaft, the reverse clutch, and the intermediate shaft.

A continuously variable transmission control system includes a continuously variable transmission device having an electricity-driven actuator that changes an width between a moveable sheave and a fixed sheave in at least one pulley of a drive pulley and a driven pulley, and a control device that controls driving of the electricity-driven actuator. The control device selects, from a plurality of speed relationships, each of which is a relationship between an input shaft rotational speed of the drive pulley and an output shaft rotational speed of the driven pulley, one speed relationship according to an input of a switch command signal or a drive state of the vehicle, and changes the width between the moveable sheave and the fixed sheave based on the selected speed relationship and detected values of the input shaft rotational speed and the output shaft rotational speed.

A reverse gear for watercrafts includes an input shaft that receives rotational power of a main engine. A forward/reverse switching mechanism includes a reduction function and switches the rotational power of the input shaft among forward, neutral, and reverse states. An output shaft outputs the rotational power of the forward/reverse switching mechanism and rotates at a rotational speed that differs from a rotational speed of the input shaft due to the reduction function of the forward/reverse switching mechanism. A reduction mechanism includes a fixed reduction ratio, and reduces the rotational power of the output shaft and transmits the reduced rotational power to a propeller shaft. A forward/reverse housing accommodates the forward/reverse switching mechanism. A reduction housing accommodates the reduction mechanism. The forward/reverse housing and the reduction housing are detachably coupled one behind the other in an axial direction of the output shaft.

A reverse gear includes an input shaft, a forward clutch, a reverse clutch, an output shaft, a reduction mechanism, and a relay shaft. The input shaft receives rotational power of a main engine. The forward clutch transmits the rotational power of the input shaft as forward output. The reverse clutch transmits the rotational power of the input shaft as reverse output. The output shaft outputs the rotational power transmitted via the forward clutch and the reverse clutch. The reduction mechanism reduces the rotational power of the output shaft and transmits the reduced rotational power to the propeller shaft. The relay shaft intersects the input shaft and relays the rotational power from the forward clutch and the reverse clutch toward the output shaft. The relay shaft and the output shaft are coupled to each other via a pair of intersecting-shaft gears to be able to transmit power.

A reduction reverse gear according to the invention of the present application includes: an input shaft to which rotational driving force from a main engine is input; a front-reverse housing accommodating forward-backward switching mechanisms with which the rotational driving force from the input shaft is switched among forward, neutral, and backward; an output shaft through which the rotational driving force from the forward-backward switching mechanisms is output; and a reduction housing accommodating a reduction mechanism with which the rotational driving force from the output shaft is reduced to be transmitted to a propeller shaft. The housings are detachably coupled to each other on front and rear sides in an axial direction. The input shaft and the output shaft are arranged on the same plane while facing each other.
