Supporting wheels are indeed key components used to support the weight of tractors (as well as tracked construction machinery such as excavators and bulldozers). The following is a detailed explanation of the function of the support wheel in supporting the weight of the tractor: First, the basic function of the support wheel. The support wheel is one of the "four wheels and one belt" (drive wheel, guide wheel, support wheel, support belt wheel, and track) of the tracked construction machinery chassis. Its main function is to support the weight of the machine and make the track move forward along the wheels. At the same time, the supporting wheels also roll on the guide rails (rail links) or track surface of the track to restrict the track and prevent lateral slippage.

2、 The working principle of the supporting wheel

Supporting weight: The supporting wheels, with their sturdy structure and wear-resistant materials, can withstand the weight of heavy machinery such as tractors, ensuring that the machinery can travel stably on various terrains.

Rolling guidance: The supporting wheels roll on the track rails or track surface, guiding the tracks along a predetermined path to ensure that the machinery can move according to the operator's intention.

Preventing derailment: The roller flange of the supporting wheel can clamp the chain rail, preventing the track from slipping laterally during operation, ensuring the safety and stability of the machinery.

3、 Characteristics of using supporting wheels

Strong wear resistance: The rim of the supporting wheel is usually made of wear-resistant materials, such as 45 steel, and is quenched to improve its hardness and wear resistance.

Reliable sealing: The supporting wheel is usually equipped with bearings and lubricating oil inside. In order to ensure its normal operation, the supporting wheel needs to have good sealing performance to prevent impurities such as mud and water from entering the interior and causing damage.

Low rolling resistance: The design of the supporting wheels should minimize rolling resistance as much as possible to improve the driving efficiency and fuel economy of the machinery.

4、 The application scenarios of supporting wheels are widely used in various tracked construction machinery, such as tractors, excavators, bulldozers, etc. These machines play an important role in fields such as farmland improvement, road construction, mining, and building construction. The excellent performance of the supporting wheels ensures that these machines can work stably and efficiently on various complex terrains. In summary, the support wheel is one of the indispensable key components in tracked construction machinery. With its unique structure and functional characteristics, it plays an important role in supporting the weight of the machinery, guiding the track forward, and preventing derailment.

The support wheel is one of the important components of tracked vehicles such as tractors, mainly playing a role in supporting the weight of the vehicle. 1. Working principle: The weight of a tracked tractor is transmitted to the supporting wheels through the body. The support wheel is installed below the track, and when the tractor is stationary, it bears most of the weight of the body, evenly distributing the weight on the track. It's like small support points that allow the tracks to better fit the ground. During the operation of the tractor, the support wheels rotate with the movement of the tracks. It not only supports weight, but also reduces the frictional resistance between the tracks and the ground, allowing the tractor to move forward, backward, or turn smoothly.

2. Structural characteristics: The supporting wheel is generally composed of components such as the wheel body, hub, shaft, and bearings. The wheel body is usually made of high-strength alloy steel to withstand enormous pressure. The wheel hub is used to connect the wheel body and the shaft, which is installed on the chassis bracket of the tractor. Bearings can ensure the flexible rotation of supporting wheels and reduce wear. In order to prevent impurities such as soil and sand from entering the interior of the supporting wheel and affecting its normal operation, the supporting wheel is also designed with a sealing device. The sealing device can effectively block external impurities and prevent internal lubricant leakage.

3. Important supporting wheels can ensure the stability of the tractor. If the supporting wheel malfunctions, such as severe wear or damage, it can cause the center of gravity of the tractor to shift, affecting its safety and comfort during driving. And it may also cause abnormal wear and tear on the tracks, shorten their service life, and increase the cost of use.
