いる。2. Description of the Related Art In a marine vessel propulsion device in which engines are symmetrically arranged, basically, as shown in FIG. 4 (a), a single shaft equipped with one propeller 5 for each engine 2 is provided. Type (see Japanese Utility Model Publication No. 4-127098),

いにくい。In the type in which each propeller is driven by an individual engine, if one engine fails, both the one-shaft type and the two-shaft type will rotate only the other propeller. If it only rotates, the moment that turns the bow to the right acts strongly, preventing normal steering. In particular, when the engine fails, the vehicle normally travels at a low speed, but at that low speed, the steering becomes difficult. On the other hand, if the two propellers are always synchronized, even if one engine fails, the steering performance will not be affected, but such a structure is advantageous for large ships with large thrust and low rpm. Although it is large, small boats equipped with high-speed engines such as runabouts and cruisers cannot always use the marine vessel maneuvering method that changes the left and right engine speeds when turning two engines synchronously. , It is difficult to make a small turn steering.

Reference numeral 1 denotes a hull of a motor boat. Through the hull 1, an engine 2, 2 and a transmission mechanism composed of a drive unit 3 including a clutch 3a and a gear 3b and a propeller shaft 4 by the engine 2 and 2 are provided. The marine vessel propulsion device is installed in which the propellers 5 and 5 that are rotationally driven are symmetrically arranged. Since the marine vessel propulsion apparatus of this embodiment has a bilaterally symmetrical structure, only one side will be described below. The engine 2 is stably installed in the hull 1, and the tip of a propeller shaft 4 having a propeller 5 attached to the tip is projected to the outside of the rear of the hull 1, and the drive unit 3 is switched and operated in a steering room. It is possible to select forward, stop, or reverse.

However, the external input / output shaft 7 is branched from the propeller shaft 4 by meshing the bevel gears 6a and 6b, which are protruded in the opposite direction and fixed to the propeller shaft 4 and the external input / output shaft 7, respectively. It has become a thing. A clutch mechanism 8 as a connecting means is provided at the abutting portion between the external input / output shafts 7, 7, and the clutch mechanism 8 is normally held in the disengagement mode. By operating the lever 8a at
It is possible to switch to the connection mode via.

も載せ換えができる。In the motor boat thus formed, when one engine fails and one propeller stops, the drive unit is once put in the stop mode, the clutch mechanism is switched to the connection mode, and the engine is started again. The torque of the other engine can be transmitted to one propeller shaft via the external input / output shaft and the clutch mechanism, and both propellers can be rotated synchronously. Therefore, the left and right propulsive forces do not become unbalanced, and steering can be performed as desired even when traveling at low speed. In the case of this embodiment, the expansion / contraction mechanism 7a utilizing the spline structure is incorporated in the external input / output shafts so that both propeller shafts 4, 4
If the distance between them can be adjusted, they can be remounted on hulls of different sizes.

がやりやすくなる。In the above embodiment, the clutch mechanism, which is a connecting means, is integrally assembled in order to connect the propeller shafts to each other by the clutch mechanism. However, the external input / output shaft is located at a position closer to the propeller than the clutch in the transmission mechanism. It does not matter if it is branched, and as shown in FIG. 2, if it is combined with the gear 3b of the drive unit 3 and both external input / output shafts 7, 7 are connected by a detachable connecting shaft 9, normal navigation is possible. Sometimes there is no connecting means between the drive units, so there is no obstruction by the external input / output shaft, and in the type shown in FIG. 4 (b), the drive units are connected before being distributed to the two shafts, so the propeller of this type is connected. Can also be used. In the case of a type in which the drive unit is arranged outside the ship, for example, in the case of an inboard outdrive engine, a window 10 for connecting the connecting shaft is provided in the housing of the drive unit 3 as shown in FIG. The connecting shaft 9 can be connected to the tip of the output shaft 7 to transmit power. In the case of connecting with the connecting shaft 9, as shown in the same figure, the waterproof cap 11 is detachably attached to the window 10 in the outboard motor, and the cross section of the tip of the external input / output shaft 7 is processed into a polygonal shape. It is desirable that the coupling 12 corresponding to the polygon is attached and an expansion mechanism is provided so that the coupling 12 can be connected to the external input / output shaft 7 with one touch. Further, if the universal joint mechanisms 13 are provided at both ends of the connecting shaft 9, the connecting work becomes easy.

It can be changed as appropriate within the range, for example, the external input / output shaft can be provided in parallel with the propeller shaft, and both external input / output shafts can be connected by engaging / disengaging the spur gear. There is no problem even if an engaging / disengaging mechanism using gears or gears is integrally provided and the structure is asymmetrical.
In addition, the operating mechanism of the clutch mechanism, such as remote control, hydraulic pressure,
Various changes are possible.

簡単に対応できる。According to the present invention, in a bilateral propulsion device for a ship, when the engine on one side fails, the connecting mechanism is connected to introduce the output from the engine on the other side and the propeller on one side also rotates. By maintaining the balance between the left and right propulsive forces, the steerability can be secured. Also, if the external input / output shaft is branched and connected to the propeller shaft via a bevel gear and the clutch mechanism is adopted as the connecting means between the external input / output shafts, each member can be rationally arranged and only the connecting operation of the clutch mechanism is required. It can be easily handled.
