1. Tracks for the rubber track undercarriage

Tracks are driven by a driving wheel, and are a flexible link that surrounds the driving wheel, road wheel, induction wheel, and carrier wheel. Tracks consist of track shoes and track pins. A track pin connects each track shoe to form a track link. There are holes at both ends of the track shoe, which mesh with the driving wheels, and induce teeth in the middle, which are used to regulate the track and prevent the track from falling off when the tank is turned or tilted. To improve the rigidity of the track shoe and the adhesion of the track to the ground.

2. Drive wheel for the rubber track undercarriage

On track operation machinery, most of the drive wheels are arranged at the rear. The advantage of this arrangement is that it can shorten the length of the track drive section, reduce the friction loss at the track pin caused by the driving force, and extend the service life of the track. It is not easy to cause the lower part of the track to arch, avoiding the danger of the track falling off during steering, and is beneficial to improving the efficiency of the traveling system. The height of the center of the driving wheel should be helpful to reduce the height of the center of gravity (or body) and increase the length of the ground contact of the track to improve the adhesion performance. Therefore, the height of the driving wheel should be as small as possible.

3. Supporting pulley for the rubber track undercarriage

The function of the idler wheel is to drag the track to prevent the track from sagging too much, so as to reduce the jumping of the track in the movement and prevent the track from slipping sideways. The carrier roller is similar to the roller, but the load it bears is small, and the working conditions are better than the roller, so the size is smaller.

4. Tensioning device for the rubber track undercarriage

The main function of the tensioning device is to realize the tensioning function of the crawler belt and prevent the belt from falling off.

The buffer spring of the tensioning device must have a certain amount of preload to cause a pretension force in the track. Its function is not to affect the meshing of the track pin and the driving gear teeth due to a slight external force or slack when forward, and to generate sufficient traction force when reversing to ensure the normal meshing of the track pin and driving gear teeth.

Due to the recoil effect of the device, the tension spring bears the guide wheel on the right side so that it always maintains a certain tension state during the work, thereby guiding the track tension guide wheel.

5. Buffer spring for the rubber track undercarriage

The main function is to cooperate with the tensioning device to achieve the elastic tensioning function of the track. Because of the role of the tensioning device, the spring is used to push the guide wheel to achieve the tensioning effect. Therefore, compression and tension springs can be used.

6. Guide wheel for the rubber track undercarriage

The front and rear position of the guide wheel is determined by the position of the drive wheel, and it is usually arranged in the front. The guide wheel is used to guide the track to rotate correctly, which can prevent deviation and derailment. The height of the center of the guide wheel from the ground should be helpful to reduce the center of gravity.

7. Track roller for the rubber track undercarriage

The track roller is one of the four wheels and one belt of the tracked construction machinery chassis. Its main function is to support the weight of the excavator and the bulldozer, and let the track advance along the wheel. The number and arrangement of track rollers should help make the ground pressure distribution uniform. Agricultural walking mechanisms mostly work in mountainous or hilly areas, and most of the roads are dirt roads. The track equipment requires a small average ground pressure, and the pressure of the rollers must be evenly distributed.

8. Walking mechanism for the rubber track undercarriage

Mainly includes the body of the crawler chassis, as a carrier platform for the above parts, to facilitate the fixing and installation of guide wheels, track rollers, etc.
