Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a motor generator designed to prevent noise.

Conventional frame constructions of motor generators are generally made of pipe frames, which are therefore heavy, and improvements are desired in terms of weight reduction. On the other hand, a motor generator generates noise when the prime mover is operating and when the generator itself is operating, so in order to prevent noise and obtain a quiet generator, the surrounding area is covered with a cover, but the cover is a flat plate. On the other hand, since the surrounding frame is made of pipe material, it is troublesome to attach one end of the cover to the pipe material, and it is necessary to separately install a bracket for attachment, which complicates the structure and manufacturing. Become.

The present invention has been made to improve the above-mentioned problems, and its purpose is to dispose the prime mover, generator main body, fuel tank, muffler, etc. on the undercarriage cover supported on the frame, and to install these components. A cover covers the four circumferences and top of the muffler, at least separates the muffler from surrounding equipment, and the cover is provided with an outside air intake and exhaust port to introduce outside air into the cover for cooling. An object of the present invention is to provide a motor generator that is simple, lightweight, and has excellent noise prevention effects.Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 shows the external appearance of the motor generator 1, Fig. 2, Fig. 6,
As shown in Fig. 7, frame members 2.3 made of amperage material or channel material are horizontally suspended before and after the lowest position, and members 2 and 3 are attached at both ends 2a and 3a to increase strength and rigidity.
The needle is bent diagonally upward. An amplifier cover 4 is mounted and fixed on the members 2 and 3, and the front and rear portions of the amplifier cover 4 are formed so as to match the shapes of the members 2 and 3, overlap with each other, and rest on the members 2 and 3. L-shaped parts projecting outward are formed at both ends 4a of the amplifier cover 4, while brackets 5 are provided at both ends of the members 2 and 3, and the outer ends of the brackets 5 are connected to the outer ends of the members. A sealing rubber 6 is attached to this portion of the device that protrudes upward, and is applied to both ends for sealing. A support shaft γ is horizontally suspended between the left and right brackets 5, and rolling wheels 8 are installed and supported at both ends of the brackets, and the rolling wheels are provided on the front, rear, left, and right sides, and these four wheels roll. . Side covers 9 and 10 are installed upward on the left and right sides of the amplifier cover 4, and the lower ends 9a and 10a of the side covers 9 and 10 are bent inward and attached to the frame member/parts using bolts and nuts 11, etc. Tie it to both ends of 2 and 3. Front and rear covers 12 are installed before and after the amplifier cover 4.
．． 13 and these covers 12.13 and 9,10
covers all four circumferences of the undercoat 4, and a top cover 14 is provided above, and the top cover 14 is covered with the side cover 9.
, 10 and the lower surface thereof. A duct portion 16 is provided in the lower part of the front cover 12 protruding forward, and a bottom hole 16 of the duct portion 16 is provided.
a and a lower hole 12a of the front cover 12 to communicate the inside with the outside air, and as shown in FIG. A through hole 4b is provided in the front part of the cover 4, a through hole 14a is provided in the middle part of the top cover 14, and a through hole 4c is provided in the middle part of the amplifier cover 4. Furthermore, the rear cover 13
An opening 13a with a large area is provided in the opening 13a, and a punch board or expanded metal is attached to this part to create a ventilation net 18.
Configure.

The above-mentioned cover essentially constitutes a frame, and the front part of this frame houses and mounts a prime mover @19 consisting of a water-cooled engine. The zero motor 19 mounted and supported via the front cover 20 has a carburetor 21 and an exhaust pipe 22 on one side, and an air cleaner 23 above.
7 between the take-out part on the upper part of the front cover 12 and the suction pipe 23a.
- A rubber rubber 24 is provided. A recess 25 that opens to the outside is provided in the front middle part of one side cover 10, and a battery 26 is housed and mounted in the recess 25, separated from the inside of the cover.
is provided. A cooling fan 28 is provided at the front of the motor 19 described above.

Behind the prime mover 19 inside the cover is provided a generator main body 29 that is operated by the generator main body 29, and the main body 29 is located in the middle part in the width direction, and is vibration-proofly supported on the center part of the rear frame member 3 via a mount rubber 30. Ru. A cooling fan 31 is provided at the front of the main body 29, and as shown in FIGS.
2, the inside of which communicates with the through hole 4C, and the main body 29
The muffler 33 is faced on the - side, and the muffler 33 is surrounded on all four sides by another separator 34 and opened to the rear, and the separators 32 and 34 are connected and connected to the amplifier cover 4, forming a box shape. We are trying to increase the strength. A radiator 35 is provided on the other side of the main body 29, and the radiator 35 faces the opening 10a in the middle or rear side of one side cover 10, and the opening has a rope portion 36 similar to that described above.
A fan is attached to draw outside air through the core to cool the hot water inside the core. A fuel tank 37 is mounted above the main body, radiator, and muffler, and the tank 37 is separated from the origin of the muffler, etc., and a separator 38 extends upward.
A seal rubber 39 is used to seal between the cover and the closed cover.

In the above, the above-mentioned cover 4.9, 10.12゜13
．． No. 14 and the like have a sound absorbing material 40 such as Dallas wool pasted on the inner surface as shown in FIG. 11 to further enhance the soundproofing effect. In addition, 41 in the figure is an operation panel provided at the upper front part.

Next, to describe its functions and effects, the prime mover 19 and generator main body 29 are covered on the outside by 4.9, 10°12.13.
14, the emission of noise to the outside is prevented as much as possible, making it possible to create a quiet generator with less noise.Also, since the inside of the cover is covered with sound absorbing material, it is possible to create a quiet generator with less noise. The soundproofing effect can be improved. By the way, the cover surrounds the four peripheries and the top and bottom, and these form a box-like cross section, and the internal separator serves as a reinforcing member, maintaining sufficient strength and rigidity without using a pipe frame, and the front and rear frame members and steel plate cover. Since it is composed of members, etc., it can be lightweight.

By the way, when the prime mover 19 is operated, the generator main body 29 is operated,
Although power is generated, the holes 16a and 12a are
. The cooling air introduced into the separator 34 flows around the separator 34 to cool it and is discharged from the rear rope section 18, while the exhaust air from the radiator 35 is directed to the side and discharged from the rope section 18. . In this way, the inside is forcibly cooled with a fan while the surrounding area is covered with a cover.

As is clear from the above, according to the present invention, the frame is composed of plate materials while achieving practical noise prevention, maintaining sufficient strength and rigidity for practical use, and reducing weight.At the same time, since the plate materials are combined, soundproofing is achieved. It has many advantages, such as simplifying the frame structure.
