Abstract

PURPOSE:To reduce the generation of noise during running and to prevent damage of a road surface, by a method wherein metallic cross beams are buried in an endless track belt consisting mainly of rubber, and a sprocket engaging hole is reinforced with the cross beam. CONSTITUTION:Sprocket holes 13 for a driving wheel are formed in a plane part nipped by adjoining triangle patterns 11c of an endless track belt. Cross beams 14 are exposed at the front and the rear edge of the hole 13, and prevents breakdown of the shape of the hole 13. The cross beams 14 are buried in the direction of the length of a track gripper 11, and only a portion facing the hole 13 is so formed to be exposed to the outside.

Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention is a high-speed endless track belt suitable for multi-purpose mobile vehicles, which can be expected to be effectively used in a wide range of fields such as civil engineering construction, agriculture and forestry, transportation, communications, and resource exploration. It is related to.

(Prior Technology) Generally speaking, mobile vehicles that travel on rough terrain such as soft ground, wetlands, sandy ground, muddy ground, sloped ground, snowy ground, etc. to carry out various types of work and transportation, etc. ) are designed to move by meshing with the drive wheels.

This type of mobile vehicle is typified by bulldozers, tractors, tanks, etc., but as mentioned above, it is prohibited to run on public roads because it is covered with steel endless tracks and the road surface is severely damaged. For this reason, the mobile vehicle must be loaded onto another transport vehicle and moved, which is extremely inconvenient. In the event of flooding, snow damage, earthquakes, landslides, forest fires, etc., mobile vehicles suited for each purpose drive at high speed on public roads and enter the site to quickly carry out rescue and reconstruction work. However, it is necessary for mobile vehicles to run on public roads and at high speeds.

(Problems to be Solved by the Invention) This invention was made to solve the above-mentioned conventional problems, namely, to provide an endless track belt that allows mobile vehicles to run at high speed on public roads. It is.

(Means for Solving the Problems) In order to solve the above problems, the present invention includes integrally molding an endless track belt having a track gripper on the ground surface side with a comb, etc. The gist of this is that a metal cross beam that engages with the sprocket of the drive wheel is embedded inside the track gripper.

(Example) Hereinafter, the present invention will be specifically explained with reference to illustrated examples. In Fig. 1, reference numeral 10 denotes an endless track belt made of rubber (or synthetic resin, etc.) with excellent abrasion resistance and durability, and is integrally molded into a ring shape.
1 are arranged in parallel at regular intervals. The track gripper 11 has fins 11 formed at both ends of every other gripper, and stabilizer pockets 12 are provided at the front and rear (in-between parts), which prevent the track belt 10 from skidding sideways. In addition, the ridges at both ends of the track grits and -11 are provided with recessed treads and flat turns 111) to prevent slipping, and the middle part is a triangular tread with an approximately triangular cross section. Turn 11
The purpose of this is to increase the ground contact area, increase traction force, prevent slipping, and have a self-cleaning effect.

Further, the plane portion sandwiched between the front and rear triangle patterns 11C will be described later. Holes 13 into which the sprockets of the driving wheels engage are provided on the left and right sides with the center of the endless track belt 10 as a border. And each hole 13
A metal cross beam 14 is exposed on the front and rear edges of 0,
This prevents the hole 13 from being destroyed. As shown in FIGS. 2 and 3, the cross beam 14 is buried along the length of the track hole 11, and only the portion facing the hole 13 is exposed to the outside, and its cross section is approximately Nuts 15 are fixed in advance at important points in the mouth-shaped groove. 1
Reference numeral 6 denotes a mouth-shaped wheel guide, and as shown in FIG. They are fixed respectively, and in this case, for use with multiple driving wheels, a pair is attached on the left and right as shown in FIG. 4. In addition,
Although the left and right wheel guides 16 may be integrated, the installation procedure is the same as when they are separate. Also,
Figure 2.

In FIG. 3, a large number of glass fibers 10a are buried inside the track belt 10 to reinforce it.

The endless track belt 10 according to the present invention is constructed as described above, and is used by being installed in a multi-purpose mobile vehicle, for example, as shown in FIG. This multi-purpose mobile vehicle 20 is equipped with a driving wheel 21, an idler wheel n, a lower roller wheel, and an upper roller wheel 24, all of which are dual-type, and the sprocket-shaped driving wheel 21 has an endless track as described above. The endless track band is rotated by engaging with the hole 13 of the band 10, and the upper and lower wheels n and 24 are fitted into the wheel guide 16. Also,
This vehicle is equipped with a hydrostatic drive system that rotates the left and right drive wheels independently, and the front and rear parts of the vehicle are equipped with a suspension system 5 to which various types of work equipment can be attached, and a suspension system 5 for controlling the attitude of the work equipment. It is equipped with a hydraulic coupler 26 and a hydraulic grator 27 for driving a working machine, so that various operations can be performed depending on the purpose. Furthermore, there are four cargo spaces behind the driver's seat, in which materials, various types of work equipment, personnel, a cabin for transporting supplies, etc. can be loaded.

The multi-purpose mobile vehicle with such a structure is equipped with the endless track belt 10 covered with rubber etc. as described above.
Unlike conventional steel ones, it can be driven on public roads as is, and can run at speeds over 40 KOIZ hours. Therefore, it is possible to go to the job site by driving on a public road, enter the site, immediately start working, and after the work is done, drive back on the public road again.

(Effects of the Invention) As explained above, since this invention is an endless track belt mainly made of rubber, a mobile vehicle equipped with it can run on public roads by itself and at high speed. This eliminates the need for a loading vehicle for transportation, significantly improving mobility, and providing excellent effects not only during various types of work, but also during disasters and emergencies. In addition, the endless track belt according to the present invention has a buried metal cross beam, so the overall strength is strong, and a part of the track belt is exposed at the edge of the hole where the sprocket of the drive wheel engages. This hole is reinforced and the wheel guide is fixed to the cross beam, helping to improve its strength.

Furthermore, according to this invention, the sound when running is quiet;
Because it is lightweight, it prevents damage to the road surface, and when the track grits and grooves on the ground contact surface become worn out, they have the advantage of being able to be recaptured.
