Description

[Detailed Description of the Invention] This invention relates to an outboard motor mount device that improves the vibration isolation effect and steering followability, and also improves workability during manufacturing.

The outboard motor will be explained with reference to FIG. 1. Reference numeral 1 denotes a mounting bracket, which is shaped like a box.

A tightening screw 2 is screwed into one end of this force bracket 1, and by fitting the recess 3 into a plate at the rear of the hull (not shown) and tightening this tightening screw 2, the mounting bracket 1 is integrated into the hull. will be done.

4 is a vertical cylinder, and from the upper end of this vertical cylinder 4, a bracket 5 projects forward as shown in FIG.

The bracket 5 is pivotally attached to the mounting bracket 1 by a shaft 6rtc, and a shaft T is inserted through the vertical tube 4, and brackets 8 and 9 are attached above and below the shaft T (see FIG. 2).

The main body 10 of the outboard motor is supported by the brackets 8 and 9, and the shaft 7rc inserted through the vertical cylinder 4 is supported, so that the main body 10 can rotate within a horizontal port relative to the hull.

Reference numeral 11 denotes a steering handle, which is attached to the main body 10 by a shaft 12.

Figure 2 shows a conventional outboard motor mounting device.
The upper mounting portion of the main body 10 supports the main body 10 by screwing nuts 14 and 15 into screws 13 inserted into the upper bracket 8 in the stern direction (longitudinal direction of the ship). There is.

16 is a mounting material. The lower mounting portion of the main body 10 includes a bracket 9 having a C-shaped cross section and provided so as to surround the shaft 7.
17.18.19 Mounting materials installed at three locations inside the
The main body 10 is supported through (see FIG. 3).

Conventional mounting devices configured in this way are mounted on the suspension side (
Due to insufficient rigidity between the mounting bracket side and the suspended side (hull body side), the steering angle tends to become larger than the steering angle, so a large force is required for steering, and tracking performance is poor. There are problems that lead to bad fatigue.

In addition, the assembly is complicated, and if the mounting material breaks, it will be divided into two parts and one side will fall into the water.

This invention provides an outboard motor mounting device that solves these problems.

Next, an embodiment of this invention will be explained with reference to FIGS. 4 and 5. As shown in FIG.
and the main body 10 are the first bolts 2 facing in the width direction of the hull.
1, the outer tube 22 and the inner tube 23 are coupled via a mount material 25 formed by interposing an elastic material 24 between the outer tube 22 and the inner tube 23.

The first bolt 21 is inserted into the inner cylinder 23, and its threaded end side passes through the bracket 20 toward the side, and a nut 26 is screwed into the end.

Further, a tightening nut 2γ for tightening the mount material 25 is screwed into the middle part of this bolt 21, and this tightening nut 21 is fitted into a detent hole 28vC provided inside the bracket 20. It looks like this.

29 is a cover for the mount material 25, and 30.31 is a mount material.

Among these, the mount material 30 serves as a buffer against thrust displacement in the backward direction and a collision with an underwater obstacle, and the mount material 31 acts as a stopper for displacement due to the thrust in the forward direction.

Next, the lower support structure of the main body 10 will be explained. As shown in FIG. They are coupled to each other via a mount material 31 formed by interposing an elastic material 36 between them.

The second bolt 33 is inserted into the inner cylinder 35, and its threaded end passes through the bracket 32 toward the front, and a nut 38 is screwed into the end.

Further, a tightening nut 39 that is tightened by the mount material 31 is screwed into the middle part of this bolt 33, and this tightening nut 39 is fitted into a detent hole 45 provided on the rear inner surface of the bracket 32. It is now possible to do so.

A collision stopper 40 is interposed between the outboard motor main body 10 and the mount material 3T.

Then, the second bolt 33 is placed opposite the stopper 40.
A cushioning material 41 and a washer 42 are fitted into the housing.

43 is a cover for the mount material 37; 44 is a stopper that restricts thrust displacement in the forward direction.

Outboard motor main body 1 explained above with reference to FIGS. 4 and 5
The upper and lower support structures of 0 are only on one side of the main body 10 divided by a vertical line, but they are completely symmetrical and have the same structure in the upper part of the figure.

This mounting device configured in this way is used by being set so that engine vibrations are swung in the left and right direction of force in the figure.

This reduces engine vibration to the upper mount material 25Vc.
Therefore, it is effectively absorbed and the propagation to the bracket 20 side, and thus to the hull side, is suppressed.

- The mount material 3T provided at the bottom effectively acts against vibrations and thrust fluctuations caused by the propeller.

In addition, the handle 11 (the first
(See figure) Good followability can also be obtained for steering by VC.

Since this invention is constructed as described above, it has the advantage of being able to improve the vibration damping effect on the engine and the ability to follow the steering.

Additionally, in this regard, a comfortable ride can be obtained.

Furthermore, the first and second bolts are fitted with a mounting material in the middle, and a tightening nut is screwed together, and these tightening nuts are attached to a rotation stopper provided inside the upper bracket and the lower bracket, respectively. the first bolt and the second bolt through the upper bracket and the lower bracket, respectively.
Screw the nuts onto the tips of the bolts to connect the first and second bolts to the upper and lower brackets, respectively. Bolts are prevented from falling off when assembling the device, bolts can be connected from outside the bracket, and workability is improved.
