- the present invention relates to a rubber crawler having the above-described configuration, and the skeleton of the rubber crawler is a structure in which a rod is connected in a rectangular shape and this block is endlessly connected. Even if it is damaged, there is no break due to a cut or steel cord corrosion, and even if a rectangular parallelepiped block that is a part of the As shown in the figure, the protrusion of the metal core has been eliminated, resulting in an extremely reliable rubber crawler.
- the rectangular parallelepiped blocks are arranged in a zigzag pattern, there is little falling of the rolling wheels, and the rubber crawler can run smoothly with little running vibration.
- the rod is a rod and is very economical because it uses inexpensive general steel round bars and steel pipes, and can reduce the production cost of rubber rollers.
- the outer dimensions of the bush can be changed to engage the sprockets of various dimensions, and the rubber and bushing are made to be erosion resistant. You can extend the life of your mouth.
- the rectangular block has a larger through-hole than the rod, and rubber is filled and bonded between the through-hole and the rod, so that the rod is fixed via rubber, which is an elastic material, and the rod is slightly stretched. It becomes a certain rubber crawler, and when a high load is applied, abnormal tension like an iron link hardly occurs, and the rubber crawler is hard to break. In addition, when the rod is stretched beyond a certain level, the rod is tightly fixed to the rectangular parallelepiped block, so there is little torsion, preventing the rubber crawler from coming off and reducing the swing of each rod. It is a rubber crawler with less vibration.
- one side of the through hole provided in the rectangular parallelepiped block is made small and the other side is made large, and furthermore, a rod body anti-skid projection is provided on the inner wall of the through hole, the torsion is further reduced as compared with the rubber crawler, and the rocking is further improved. It becomes a rubber crawler with little movement.
- the protruding portion of the rubber crawler on the inner peripheral side of the rectangular parallelepiped block serves as a guide for preventing the rolling wheels and idler wheels from coming off. If the protruding portion is square, the rectangular parallelepiped block will be inexpensive, and the protruding top will extend in the crawler circumferential direction. In this case, it becomes a wheel rolling part.
- the wings attached to the rectangular block are extended in the circumferential direction of the crawler, they become the rolling surfaces of the axle wheels. If the wings are arranged between the rods, the same effect can be obtained and the rectangular block is inexpensive. It becomes an economic rubber rubber.
- Side slip prevention parts are formed at both ends in the length direction of the rectangular parallelepiped block, and when embedded in the rubber crawler, the side slip prevention parts of the adjacent rectangular blocks in the front and rear direction of the crawler circumferential direction and the side slip prevention in the crawler circumferential direction In a rubber crawler having an overlapping portion, lateral displacement of the rubber crawler can be prevented, and the rubber crawler can be prevented from coming off.
- the driving force transmitted from the sprocket to the rod is transmitted to the entire rubber crawler in a well-balanced manner, and a sufficient traction force can be obtained.
- the local stress near the rod is alleviated, and the durability of the rubber crawler is improved.
- Rubber crawlers with connecting rings reduce the distortion that occurs repeatedly in the rubber between the rectangular blocks when the crawlers are wound around the driving wheels and idler wheels, and prevent rubber fatigue between the rectangular blocks. I do.
- the connecting ring assists in fixing the rod body, the rubber crawler has less vibration, prevents derailing, and has a high strength rubber crawler.
- the connecting ring is springy and stretches, so even if a high load is applied, no abnormal tension occurs and the rubber track is difficult to break.
- the connecting ring increases the rigidity between the rods, disperses the driving force transmitted from the sprocket to the rods, and effectively transmits the driving force to the lugs, thereby obtaining a sufficient traction force.
- the transmission of the driving force becomes uniform and the rigidity of the rubber track is increased, so that a reliable traction force can be obtained.
- a rubber crawler provided with a connecting ring if lugs are shifted by a half pitch with respect to the connecting ring in the crawler circumferential direction, since the lug exists over the adjacent connecting rings, The rigidity is increased and the whole rubber crawler becomes uniform rigidity, and a more reliable traction force can be obtained, and also a favorable effect can be obtained in preventing wheel derailment.
- the rod In a rubber crawler provided with a rectangular parallelepiped auxiliary block having a through-hole larger than the outer diameter of the rod, the rod is fixed via rubber, which is an elastic material. Abnormal tension even when load is applied It is hard to break down and the rubber crawler is hard to break. On the other hand, when the elongation exceeds a certain level, the rod is firmly fixed, so that the rubber crawler has less vibration and is difficult to lose its wheel.
- the top surface of the rectangular parallelepiped auxiliary block serves as a rolling surface of the outer wheel.
- Unit rubber crawler unit is formed, and only unit rubber crawler units of the same type are connected to form an endless rubber crawler unit.
- Unit rubber crawler units of various configurations are formed, and endless rubber units are connected in appropriate combinations. In the case of a crawler, even if the rubber rubber ⁇ -i-la is partially damaged, it is possible to obtain only that part of the crawler. Costs can be reduced, and waste is reduced and disposal becomes easier.
- the rubber part that encloses the pipe can be easily attached and detached, and if the rubber part is damaged, it can be replaced easily, making repairs easy and maintenance costs low. Can be reduced. If the wall of the pipe is coated with a thin layer of a polymer compound such as rubber, the noise generated by friction between the rod and the pipe can be prevented, and the rod can be stably fixed to the rod.
- the rubber chopper which is configured to divide the band formed on the outer part of the rectangular parallelepiped block, can be replaced by the damaged part if the rubber part is damaged. It is.
- the band is divided into a single body including two rods, the unit parts are reduced in size and the replacement work is facilitated, and the manufacturing apparatus may be small in size and the transportation work is easy.
- the rubber belt which has a structure in which the end of the divided strip is in contact with one end, has no gap between the single or ended strip, and prevents mud and foreign matter from rising to the inner peripheral side. This prevents abnormal tension caused by squeezing between the sprocket and the rubber crawler. The risk of derailing can be prevented, and in soft terrain, settlement can be prevented and turning performance can be prevented.
