り、またガイド突部が破損する可能性がある。The crawler traveling body as described above has a structure in which the driving force is transmitted to the crawler body by the engagement between the drive pin and the guide protrusion, and in this structure, the crawler body is directly connected to the guide protrusion. Since the driving force is applied, securing its rigidity becomes a problem. Therefore, it is necessary to increase the height and thickness of the guide protrusion, and to increase the rigidity by providing a bulge between the guide protrusions as in the crawler traveling body described above, but the guide protrusion is the same as the crawler body. Since it is also made of an elastic material (made of rubber), power transmission loss may easily occur due to engagement with the drive pin, and the drive force may not be transmitted sufficiently, and the guide protrusion may be damaged. .

I may not be able to. Therefore, the present invention has been made in view of the above problems, and by providing a meshing member that meshes the drive wheels between the guide protrusions without transmitting the drive force to the guide protrusions, reliable driving force transmission can be achieved. It is an object of the present invention to provide a crawler traveling body that can improve the strength of the guide protrusion at the same time.

防止機能を高めている。The drive wheel 8 is formed in the shape of a sprocket and has a plurality of meshing blades 8a formed on the outer circumference thereof. The guide protrusion 4 is provided so as to bridge both roots. The meshing member 5 is made of a metal or hard resin cylindrical pipe material, and both ends of the meshing member 5 are buried up to substantially outer surfaces of the left and right guide protrusions 4 as shown in FIG. ing. In the side sectional view of FIG. 1, the engagement member 5 is provided so as to bulge from the inner peripheral surface of the crawler body 2. The meshing member 5 reinforces the guide projection 4 by connecting the left and right guide projections 4, and both end portions of the meshing member 5 are embedded until reaching substantially the outer side surface of the guide projection 4.

とができ、軽量化、コストダウンを図ることができる。The arcuate portion of the upper outer peripheral surface of the meshing member 5 serves as a meshing surface 5a with the drive wheel 8, and the meshing blade 8 of the drive wheel 8 is formed.
The groove portion between a is an arc-shaped meshing surface 8b that abuts against the meshing surface 5a, and both meshing surfaces 5a and 8b are formed in a shape along each other. Therefore, the mesh surface 5 of the mesh member 5
a and the meshing surface 8b of the drive wheel 8 are smoothly meshed with each other to improve the power transmission capability, and each has an arcuate shape. Therefore, the meshing surface 5a of the meshing member 5 after meshing and the drive wheel The meshing surface 8b of 8 can be separated from each other, and the crawler main body 2 makes a smooth orbit. By forming the meshing member 5 with a cylindrical pipe material, a lightweight and highly rigid meshing member 5 can be obtained, and the weight and cost can be reduced.

より軽量化を図ることが可能である。Since the meshing with the drive wheel 8 is made by the meshing member 5 made of a hard material (metal, hard resin, etc.),
Reduces power transmission loss. By embedding the same rubber material as that of the crawler body 2 and the guide protrusions 4 in the pipe of the engagement member 5, it is possible to firmly fix the engagement member 5 between the guide protrusions 4. Although the meshing member 5 hardly separates when meshing with the meshing blade 8a of the ring 8, the rubber material may not be embedded in the pipe of the meshing member 5 and may be hollow. ,
It is possible to further reduce the weight.

いる。Further, according to the above construction, unlike the conventional drive wheel, an engaging pin which engages with the guide projection 4 is not required, so that grass, mud, etc. are hardly caught in the drive force transmitting portion, and the power is reduced. The transmission is smooth and the guide protrusion 4 is not damaged. The shape of the guide protrusion 4 may be formed by considering only the position regulation of the drive wheels 8, the rolling wheels 9, the driven wheels, etc., so that the flexibility of forming the guide protrusion 4 is increased.
That is, it is easy to improve the function of preventing the drive wheels 8 and the like from slipping off, and to reduce the cost and the weight.
