Crawler undercarriage is used walking component of construction machinery.If they can be used reasonably and operated scientifically,then will extend the working service life effectively.How to extend the life of excavator crawler chassis undercarriage track chain assembly?

 

To avoid the crawler track wear

During normal operations,it is easy to wear the chassis when the operator's operating habits or the impact of the working condition.it is possible to regularly switch the machine position during operations to reduce excessive unilateral wear. When conditions do not permit or the meshing parts of the excavator accessory sprocket and tracks link have developed severe wear, the machine can be stopped to remove the left and right track chain, and the excavator track link chain replacement method can be used to reduce excessive wear of the undercarriage chassis.

 

Reasonable operation to avoid non-standard actions

There are scientific operating specifications for on-site operations that should be observed strictly, especially during prolonged load operations when traveling repeatedly on inclined ground or suddenly turning, which can easily lead to wear due to the contact between the track link assy,sprocket and idler. Timely maintenance should be avoided as much as possible during use.

 

Don’t forget he inspection and maintenance of excavator accessories and crawler undercarriage.

During working, components bolts nuts of track roller,carrier roller,track shoe,track chain link assy ,sprocket, idler become loose due to prolonged operation of the equipment or excessive vibration. The loose bolts can easily cause abnormal clearance between the bolts and the track shoes or cracks in the track shoes after being stressed, leading to a sharp reduction in the service life of the track link chain. Therefore, it is best to regularly inspect the doolincm excavator accessory tracks during use based on the usage status, and reinforce the loose bolts and nuts, which can also effectively enhance the service life of the excavator accessory track chassis.

 

 

1. Don't use detergent indiscriminately

Maintaining wheels is the same as maintaining a car. Many household detergents and dishwashers commonly used on the market are basically too strong for the surface of the wheel hub due to their alkaline or acidic nature, which will cause chemical reactions on the surface of the wheel hub and lose their luster. The relationship is beautiful. Be careful when using. You can choose a little neutral soapy water to rinse.

2. Do not wash the wheels when they are hot

When the hub temperature is high, it should be cleaned after cooling. Do not use cold water to cool down, this will damage the wheel hub, and even cause deformation of the brake disc, affecting the braking effect.

3. Clean the wheels clearly

Well-cleaned wheels should be cleaned with neutral soapy water and wiped with a soft cloth at the same time. After cleaning, the surface of the wheel hub should be coated with corrosion-resistant products to maintain the surface brightness. If the aluminum alloy wheel rim hub is glued with asphalt that is difficult to clean, if it has no effect, you can use a cleaner to remove it with a brush, but be careful to avoid using hard brushes, which can easily damage the surface of the wheel hub.

Copycat car wheels or counterfeit car wheels have caused many tragedies. But if you are buying a large-scale forged car wheel, then don't worry about using it. In fact, in terms of strength, large-made car wheels are stronger than original car wheels, even though they are lighter.

As for the service life, it depends on whether you switch to a low flat ratio tire. If the tire specifications remain the same as the original factory, then just use it with confidence. Remember that the premise is to use genuine forged car wheels. However, if you switch to low-flat-ratio tires, you need to be careful. If the flat-ratio is lower than 40, don't try difficult actions such as high-speed pit punching and speed bumps. Slowing down honestly is good for tires, wheels, shock absorbers, tower tops and even the body. Lightweight automobile wheels are actually an effective means to reduce the quality of non-spring loads. This will make the bounce under the spring more neat. High speed will not be “light”, but will be more stable.The braking distance will theoretically be shortened, but I haven't tested it specifically, and I can't feel it. As for steering, it will definitely help, but it is also difficult to quantify.What is energized and can be felt is the acceleration of performance improvement.

The selection of wheels, how to choose the best one?Many people will transform the car at will in order to change the performance of the car, and the transformation of the car requires professional knowledge.

Don't blindly increase the wheels.Some people increase the wheels to improve the performance of the car. When the outer diameter of the tires remains the same, the large wheels are bound to match the wide and flat tires. The lateral swing of the car is reduced, and the stability is improved. When cornering, it is like a dragonfly, passing lightly.However, the flatter the tire, the thinner its thickness, the worse the shock absorption performance, and greater sacrifices must be made in terms of comfort.In addition, if there are a few roadblocks such as stones, the tires can easily be damaged.Therefore, the cost of blindly increasing the wheelhub rim cannot be ignored. Generally speaking, it is most appropriate to increase the size of the original wheelhub rim by one or two inches.

This means that when choosing, you can't choose your favorite shape as you want, and you have to follow the advice of the technician to consider whether these three distances are appropriate.

The complex and dense wheels are indeed very beautiful and appear to be of high grade, but it is easy to be refused to wash or overcharged when washing the car because it is too troublesome to wash.The simple wheels are full of movement and clean.Of course, if you are not afraid of trouble, it's okay. Nowadays, the aluminum alloy wheels that are deeply popular with the people, compared with the iron-cast wheels in the past, the degree of deformation resistance has been greatly improved, the weight has been greatly reduced, the power loss of the car is small, it runs fast, saves fuel and has good heat dissipation. It is loved by the majority of car owners.

The following factors need to be considered when choosing a car wheel：

Tire size and type: The size and type of tires of different models are different. The wheel hub size should be selected according to the actual size and type of the vehicle.

Vehicle performance requirements: Different wheel sizes will affect the performance of the vehicle, such as acceleration, braking and handling.Choose the appropriate wheel size according to your own needs.

Driving conditions and driving habits: Different driving conditions and driving habits have an impact on the wear and service life of the wheel hub. The size of the wheel hub should be selected according to the actual situation.

Wheel material and manufacturing process: Different wheel material and manufacturing process will affect the quality and price of the wheel, and the appropriate wheel should be selected according to the actual situation.

In short, choosing the size of an automobile wheel hub requires comprehensive consideration of multiple factors, and trade-off and selection according to the actual situation.It is recommended to choose a regular manufacturer and brand when choosing wheels, and consult a professional auto repair master or salesperson.

1.Driving comfort has been improved.

Because aluminum alloy wheels have the metal characteristics of absorbing vibration and rebound, they have high dimensional accuracy after being processed by CNC machine tools.It's really round.Partial swing and small beating.The balance is very good, which can make the car very smooth and comfortable.

2.Fuel-saving and normal driving.

Due to the light weight of the aluminum wheels, the rotational inertia of the four wheels is reduced after replacement, the acceleration of the car is increased, the braking energy demand is reduced, and the fuel consumption is reduced.

3. Improve driving safety.

The heat dissipation coefficient of aluminum alloy wheels is three times that of ordinary steel wheels.At the same time, combined with the structural characteristics of aluminum alloy wheels, when driving for a long time, the heat generated by the tires and braking system is discharged into the air to maintain the appropriate temperature.

4.The beauty of the whole vehicle is improved.

The exterior design of the aluminum wheels is very exquisite.The shapes are diverse, and the integration of the wheels can also be realized to show its beauty and enhance the beauty of the vehicle.

The classification of automobile wheels can be divided according to material, structure, use, etc.

According to different materials, wheel rims can be divided into aluminum alloy wheels, steel wheels and carbon fiber wheels; according to different structural forms, wheel rims can be divided into monoblock wheels, multiple-piece wheels and tire-studded wheels; according to different uses, wheel hubs can be divided into ordinary wheels, sports wheels and racing wheels.

Aluminum alloy wheels are widely used in modern automobiles. They have the advantages of light weight, beautiful appearance, high strength, and good heat dissipation. They can improve the power performance and handling performance of automobiles.

However, the price of aluminum alloy wheels is relatively high, and they are easy to break, and they require frequent maintenance and maintenance.

Steel wheels are wheels used in traditional automobiles, which have the advantages of being strong, durable, and more affordable.

However, the weight of the steel wheels is too large to improve the handling sensitivity and acceleration performance of the car.

Carbon fiber wheels are a new type of wheels with a high strength-to-weight ratio, which can significantly improve the handling and power performance of automobiles, and are favored by racing cars and some sports car owners.

However, the production cost of carbon fiber wheels is higher and the price is expensive.

A single-piece wheel hub is a widely used type of wheel hub in automobiles today. It is made of a piece of aluminum alloy or steel material, which is lightweight and beautiful.

However, the production of single-piece wheels is more difficult and the production cost is higher.

The multi-piece rim is composed of two or more small wheel discs, with a detachable structure, which is easier to maintain and replace.

However, the splicing structure of multiple wheels reduces the overall strength, and it is not as beautiful as a single wheel.

Tire-studded wheels have the advantages of high strength, non-slip and air leakage, and are commonly used in heavy-duty vehicles such as trucks.

However, the weight of the tire-studded wheels is large, which will affect the fuel consumption and driving performance of the car.

Taken together, each type of wheel rim has its own unique advantages and disadvantages. Consumers should choose suitable wheels according to their own tastes, models and uses.

The aluminum material is relatively light, which can reduce the quality under the shock absorber and ensure a good suspension reaction speed. There is also the good heat dissipation performance of aluminum.

1. Fuel saving

On average, each aluminum alloy wheel is 2kg lighter than a steel wheel of the same size, and a car can save 10kg in weight with 5.According to Japanese experiments, for every 1kg reduction in the weight of a 5-seater car, about 20L of gasoline will be saved in a year.A research report published by the American Society of Automotive Engineers pointed out that although aluminum alloy wheels are more expensive than ordinary steel wheels, when each car reaches 20,000 kilometers, the fuel savings will be enough to offset the cost.

2. Strong and durable

The strength of aluminum alloy wheels in terms of impact resistance, tension resistance and heat resistance is higher than that of steel wheels.This is also one of the reasons why aluminum alloy plays an important role in the national defense industry and the aviation industry.

3. Good true roundness

The accuracy is as high as 0.05mm, and the operating balance performance is good, which is conducive to eliminating the general long body and steering wheel jitter.

4. Good heat dissipation

The heat conduction coefficient of aluminum alloy is 3 times that of steel.The heat dissipation effect is good. During long-distance and high-speed driving, the tires can also be kept at the appropriate temperature, so that the brake drums and tires are not easy to age, increase life, and reduce the chance of a flat tire.

5. Increase engine life

According to the graph of engine load and power, when the load increases to a certain extent, its power decreases in reverse. This marginal value means that for every unit of load at this time, the engine will be more laborious (especially fuel consumption), and the engine load will be reduced, which will naturally reduce failures and extend life.

6. Beautiful appearance

Generally, steel wheels are limited in production, their form is monotonous and rigid, and they lack changes; aluminum alloy wheels have a variety of designs, plus good gloss and color effects, thereby improving the value and beauty of the car.

1. High temperature

Frequent flat tires in summer have a lot to do with the high temperature in summer.Because, once the road surface temperature rises, the friction between the tire and the road surface causes the tire surface temperature to be very hot.Under thermal expansion and contraction, the tire carcass rises and thins, and then it can easily lead to a flat tire.

2. Overload

In China, it is relatively common for freight cars to be overloaded, and it can almost be said that no truck is not overloaded.This is why the flat tire rate of trucks remains high, because when the actual load of the car exceeds the large allowable load of the wheels, a flat tire will occur.

3. Bad road conditions

This is the same as the reason for the wear of one's own shoes.With the same pair of shoes, walking on uneven roads will of course wear out faster than walking on flat roads.Moreover, at high speed, the tire can easily be hit by sharp objects on the road and cause a flat tire.

4. High speed

Many people don't understand that speeding can also cause a flat tire, and think it is unlikely.In fact, the possibility of a flat tire overspeed is very high.Because excessive speeding for a long time will cause the tire temperature to rise rapidly, which will cause the rubber to age rapidly and the tire to burst.

5. The air pressure does not meet

Both too high and too low tire pressure can cause a flat tire. A tire that is too high is like a balloon filled with too much gas, which can easily cause a flat tire after being squeezed.Tires with low air pressure will cause the contact surface between the tires and the ground to become larger, and the frictional resistance will also become larger when driving. When the car is driving at high speed, the tires heat up quickly, which makes it easier to make the tires high temperature, which is more likely to lead to the discovery of a flat tire.

6. “Work with illness”

Tires will cause serious wear and tear after long-term use. If the owner is still using them at this time, it can easily lead to a flat tire.
