Why is it better to move on tracks than on wheels on rough mountain roads?

The track is a flexible chain link driven by the driving wheels and surrounded by the driving wheels, load wheels, inducing wheels and carrier pulleys. The track consists of track shoes and track pins, etc. Track pins connect the individual track shoes to form a track chainlink.

There are holes at both ends of the track shoe, which are meshed with the driving wheels, and there are inducing teeth in the middle to regulate the track, and prevent the track from falling off when the tank turns or rolls over, and there are reinforced anti-skid ribs (referred to as patterns) on the side in contact with the ground to improve the firmness of the track shoe and the adhesion between the track and the ground.

According to the structural type, tank tracks can be divided into two categories: metal pin hinge type and metal rubber hinge type. Among them, metal rubber hinges can be divided into two types: single-pin type and double-pin type.

The metal pin crawler has a simple structure, direct dry friction between the pin and pin hole, fast wear and short life, and it is often found that the track pin is ground into when the tank is repaired and maintained"Sugar gourd"Shape. Track pins are also one of the wearing parts.

Metal rubber hinged track, is vulcanized on the metal pin a plurality of rubber collars, pressed fit in the track shoe pin hole, in this way, there is no direct friction between the track pin and the track shoe pin hole, only the rubber collar produces elastic torsion when torsion, the noise is small, the life is long, of course, the structure is more complex, and the cost is higher. The two-pin metal rubber track is connected with the two pins of two track shoes with end connectors, which is good under stress and easy to disassemble and assemble, but the structure is more complex, and it is the mainstream track form on the main battle tank.

Rubber shoes. The rubber track chassis is mostly suitable for small light industry and small construction machinery industry. The light industry is generally agricultural machinery within one ton to four tons. The construction machinery industry is mostly used in the small drilling industry.

The choice of the operating environment is roughly as follows:

1) The service temperature of rubber tracks is generally -25 +55'c.

2) The salt content of chemicals, engine oil and seawater will accelerate the aging of the track, and the track should be cleaned after use in such an environment.

3) The road surface with sharp protrusions (such as steel bars, stones, etc.) will cause trauma to the rubber track.

4) The curb stone, rut or uneven pavement of the road will cause cracks in the grounding side pattern of the track edge, and this crack can continue to be used when the wire cord is not damaged.

5) Gravel and gravel pavement will cause early wear on the rubber surface in contact with the load-bearing wheels, forming small cracks. In severe cases, moisture intrusion causes the core iron to fall off and the steel wire to break.

The track has low requirements for the road surface and outstanding cross-country ability.

Tracks provide better protection than tires.

Rough mountain roads can hurt tires, while tracks don't.

Tracks are able to protect the tires, which are too damaging with the wheels.

The track contact area is large, which reduces the degree of damage.

Although the track moves slowly, it is much safer.

Because the mountain road is rough and bumpy. If you move it on wheels, it will damage the tires.

Increase the force area, as well as friction. The mountain road is not easy to walk, and the contact surface of the wheels is not enough.

Because the mountain road is uneven, the tires wear out too quickly.

Tracks are more convenient and safer.

It has a certain protection function and is also more convenient.

1) Track suspension, which has a fixed or adjustable, independently offset idler block to change the track profile without affecting the track tension;

2) eccentric bearing housing on the drive sprocket controls the track tension;

3) On the drive sprocket, it is sharpened on the outer blind or circumferential edge of the shape of Zhixiao to prevent the accumulation of ice and mud;

4) Rubber coated, plastic idler pulleys for easy track movement.
