Advantages Of Airbag Suspension

Advantage 1: Good shock absorption effect

The airbag suspension can provide a good shock absorption effect for the vehicle. This utilizes the compressibility of the air. The airbag suspension can achieve a "soft connection" compared to the steel plate suspension. The deformation of the airbag is faster and superior than that of the steel plate. The airbag suspension can provide good shock absorption for the vehicle.

The airbag vehicle has a good shock absorption effect, and is often used in vehicles that transport some goods such as glass and precision instruments. In recent years, domestic truck drivers have increased the comfort requirements of vehicles. Many vehicles that transport ordinary cargo have begun to use airbag suspension, and the airbag suspension brings more than comfort to the owner.

Advantage 2: More fuel saving

It is said that the vehicle with the airbag suspension will be more fuel-efficient. It is estimated that many people will not understand why, but let me talk about how the airbag suspension can save fuel.

For example, when the vehicle walks to a bumpy road, should it slow down slowly? At this time, if the vehicle is suspended by the airbag, it can pass the bumpy section without deceleration or a small deceleration.

After the vehicle decelerates, it needs to accelerate to the normal speed. This process needs to consume more fuel. The airbag suspension has good shock absorption capability, which allows the vehicle to pass quickly, and minimizes the impact of the bumpy road on the speed of the vehicle. It will save fuel.

Advantage 3: Protect the chassis components

Thanks to the good damping effect of the airbag, the vibration from the road surface can be minimized, the damage to the chassis components due to vibration can be minimized, and the looseness of the screws on the chassis can be avoided. For the simplest example, the airbag suspension will greatly reduce the chances of the trailer being opened. Import trucks are very durable, in part because they use airbag suspension.

Advantage 4: Convenient hanging transport

The airbag-suspended tractor makes the sling transport faster. The ECAS system can be used to quickly adjust the height of the airbag, and the fastest connection and detachment can effectively reduce the number of swaying the trailer legs. It is precisely because of the convenience of hanging transport, more and more logistics companies are now using airbag suspension.

Advantage 5: Facilitate loading and unloading of goods at different heights

Today's vehicles need to stop at the platform for loading and unloading goods. There will be gaps in the platform height of different goods yards, which may cause inconvenience to the forklift or the land cows entering the vehicle for loading and unloading goods. If the vehicle is equipped with an airbag suspension, the height of the airbag can be adjusted so that the height of the vehicle's cargo box is consistent with the height of the platform to facilitate loading and unloading.

Advantage 6: Save tire protection pavement

Because the airbag suspension is a "soft link" when the vehicle is driving on a road with poor road surface, the tire fits well with the road surface, and does not cause the tire to be in contact with the road surface to accelerate the wear of the tire like a leaf spring. Therefore, the airbag suspension can reduce the wear of the tire. At the same time, thanks to the "soft link" of the suspension of the airbag, the tire will have much less damage to the road surface and can also protect the road surface.

How to Purchase a Best Refrigerated Trucks

In recent days, the high temperature and the coming of summer have made refrigerated trucks more and more popular. With the rise of the cold chain logistics industry in recent years, the demand for refrigerated trucks in the market is also growing. Many customers ask about refrigerated trucks. For this information, we have compiled some information to help you understand how to choose a stable and reliable refrigerated truck.
The choice of refrigerated trucks is basically similar to the selection of other special vehicles, mainly in the chassis, refrigerated box, and key components.

Chassis

1.Truck chassis or semi-trailer

The main reason is to see how much the cargo is transported and the distance of transportation. Generally, the short-distance light truck chassis is selected, and the medium and long-distance cargo volume is large, use heavy truck chassis, or traction semi-trailer.

2, Buy the chassis yourself or commission a refrigerated truck manufacturer
In fact, buying a chassis and commissioning a refrigerated truck manufacturer is the same. Many buyers think that the manufacturer of the refrigerated truck will purchase it. The manufacturer will make money in the middle. In fact, the manufacturers often purchase the modified chassis and generally have a good relationship with the chassis supplier. The chassis is cheaper and more suitable for retrofit production.

Refrigerated box

1, According to the quantity of the cargo

The choice of car is related to the specific cargo being transported. Customized according to the specific needs of users. For example, a refrigerated truck carrying fresh meat needs to be equipped with a stainless steel hanging meat hook on the car body; a long-sized car can be installed with a floor ventilation trough as needed; and frequent loading and unloading requires a multi-purpose refrigerating truck. Manufacturers can be customized according to the specific needs of users.

2, Change ordinary cargo box refrigerator box

Many customers ask whether ordinary containers can be changed into refrigerators. They think that it is more cost-effective to use ordinary containers. The answer is yes, but it is not recommended to use ordinary boxes to change refrigerators. Because the general cargo compartment is made of iron or steel, the insulation effect is very poor, and it is also easy to rust.

Refrigeration unit
When selecting a refrigeration unit, it is determined according to the temperature required to transport the cargo. The temperature can be adjusted from 5 degrees to minus 15 and 18 degrees.

1, Independent unit or non-independent unit

Non-independent refrigeration units are cheap and easy to maintain. However, the unit itself does not have a power unit, and it must rely on the automobile engine to drive the compressor; it is affected by the working condition of the automobile engine and the performance is not as good as that of the independent unit.

The freestanding refrigeration unit itself has an engine and generator unit that provides power and electrical energy to the refrigeration system. Can work independently, regardless of the working state of the car engine. The performance of this cold machine is relatively stable, but the price is higher and the accessories are more expensive.

Non-independent refrigeration unit

For short-distance distribution within the city or between districts and counties, the car is about 7 meters or less. It is recommended to use non-independent units. Not only is the procurement cost lower, but even if there is a failure, the maintenance is relatively convenient.

For long-distance transportation, if the car is more than 7 meters, it is recommended to use a free-standing chiller, because even if the car engine stops working during long-distance transportation, the chiller can still be cooled normally to meet the safety of the articles being transported.

2, Cryogenic unit or fresh-keeping unit

In terms of price, the cryogenic unit is expensive and the cooling temperature is lower. Fresh-keeping units are relatively cheap. However, for a cheap fresh-keeping unit, the unit itself does not have a defrosting function. At the time of purchase, choose the cryogenic unit or the fresh-keeping unit according to the temperature requirements of the goods transported by the refrigerated truck.

3, Imported refrigeration unit or domestic refrigeration unit

The imported refrigeration unit is expensive and has good refrigeration effect, and is suitable for users with strong economic strength. Domestic refrigeration units still have a certain gap with foreign brands in temperature control, especially in semi-trailer refrigerated trucks.

Three Kinds Of Engine Brake System

Engine braking, also known as engine retarder, is a relatively low-cost auxiliary brake that is now standard on many heavy duty trucks .

1. Exhaust brake

Exhaust brake is one of the most familiar forms. It is also very simple. It is installed by adding a butterfly valve to the exhaust pipe, and increasing the pressure of the exhaust stroke by closing the valve, and using the generated negative pressure to obtain the system. power. The cost is relatively low and the structure is simple.

This device is almost standard in domestic trucks, including light trucks. However, the exhaust brake is easily affected by factors such as damage to the exhaust manifold gasket, air leakage from the butterfly valve, unstable operation, and low braking power, which cannot meet the demand of heavy-duty trucks.

special truck manufacture

2. Deflated engine brake

Deflated engine braking, also known as exhaust valve braking, is divided into passive and active.

Passive requires an exhaust brake butterfly valve to match. When the engine brake switch is actuated, the exhaust brake butterfly valve is first closed, so that a high back pressure is formed in the exhaust pipe of the vehicle, so that the exhaust valve opens at a small angle, and then an exhaust mechanism is caused by a set of actuators. This valve opening is maintained during each stroke, and the compressed air leaks out from the exhaust valve during the entire compression stroke, reducing the energy returned to the piston to achieve the effect of braking deceleration, but the passive butterfly valve is affected by the working state. Large, especially when the engine speed is relatively low, the effect is relatively poor.

3. Compression release

Compressed release engine braking is the current mainstream engine braking technology, and it is also the one with the highest braking power and efficiency. When the control switch is turned on, the engine exhaust valve is opened near the top dead center of the compression stroke, and the high pressure gas formed during the compression stroke is discharged out of the engine cylinder. In this way, most of the energy absorbed by the compressed gas is emitted, and only a small portion of the residual energy pushes the engine piston back. As the engine repeats, the inertia of the vehicle as it descends will be dissipated by the engine's compression-release action, eventually decelerating the vehicle.

Simply put, compression-release engine braking is to turn the engine into an air compressor. In this way, the braking power is large. In order to improve the adaptability, it is divided into two gears. In the first gear, only four cylinders produce braking effect, and the second gear and six cylinders all participate in the work to achieve different adaptation. The purpose of weight and slope.

Basics Part3 Braking System And ABS

To truly evaluate the braking performance of a vehicle, you need to design three dimensions of indicators:

1) Braking performance.

That is, braking force and braking distance;

2) Stability of braking performance

Braking heat and water will cause performance degradation, so it is necessary to evaluate the thermal decay resistance and water degradation resistance of the brake;

3) Stability of the vehicles direction during braking

In other words, the brakes must not only stop the car, but also stop the car at the driver's designated place. This does not allow the vehicle to experience side slips (locking the rear wheels), losing steering ability (locking the front wheels), etc. - how many accidents are caused by the loss of control of the vehicle while braking.

braking system on trucks

The role of ABS is not to reduce the braking distance

It is often seen that everyone is discussing whether the braking distance is increased or decreased after installing ABS. In fact, the card friends who discuss this issue may not understand the design purpose of ABS.

Still returning to the question raised at the outset: Evaluating the braking ability of a car is divided into three dimensions. The simplest and most effective way to reduce the braking distance is to increase the braking force of the vehicle - a large brake drum and a wider tire. The emergence of ABS is to solve the third problem: to improve the direction stability of the vehicle when braking - its name translated into Chinese is actually "anti-lock braking system."

Many old drivers know that the car's front wheel lock will cause the vehicle to lose steering ability; if the rear wheel is locked, there will be a tail-flick phenomenon (the high-level brothers will drift according to this principle). The best braking state is to let the wheels "slip on the side". At this time, the braking distance is short and the car will not get out of control. Therefore, before the ABS, the old driver will use the brake method to let the vehicle enter this state.

To sum up, the brakes are lightly pressed, and the brakes are not big enough when the wheels are completely locked. If the brakes are heavy and the wheels are completely locked, the direction is easy to get out of control, so it is necessary to grasp the middle degree. Everyone knows that the reaction speed of the machine must be much faster than people, so use the sensor, small motor to help people operate the brakes, and find the middle one that can take into account the braking distance and the stability of the brake.

Safety Operation Guide for High-altitude Operation Truck

Aerial work trucksare often used in the high-altitude operation range of municipal wires, street lamp maintenance, high-rise exterior wall maintenance, highway billboard maintenance, etc. The chassis of the aerial work vehicle is composed of the chassis of the car plus the lift. Because it requires long-term use and high-altitude operations, the vehicle chassis requires a higher strength in the manufacturing process than the chassis of other ordinary cars. In order to be able to well guarantee the safety factor of personnel who need to work at high altitudes for a long time, their operators need to pass comprehensive safety knowledge training before they can start work. Then there are several safety common senses about aerial work vehicles:

Aerial working truck

1. When performing high-altitude work on high-rise buildings or high-voltage lines, etc., it is necessary to pay attention to the need to keep a safe distance from the lift. However, if you need to get close to it in some unavoidable circumstances, you should let other staff observe the surrounding situation more, evacuate the crowd, and maintain a normal conversation.

High-altitude Operation Truck

2. When the operator of the aerial work vehicle is performing high-altitude operations, he must wear the prescribed safety clothing and related machinery to ensure good communication between the upper and lower personnel. Communication equipment and communication gestures are also necessary. In addition, you cannot not wear safety clothing and machinery because of the low operating height. These common sense are the basic safety awareness that must be known when performing high-altitude operations. The staff operating at high altitudes must have good communication skills with the personnel below, be equipped with communication equipment, and be familiar with communication gestures. When working, every misunderstanding of the gestures used in communication will cause inevitable losses.

Aerial platform truck

3. Check and maintain the hydraulic system, lift, and brake system of the aerial work vehicle on time and regularly. The hydraulic system also includes the hydraulic oil tank and various high-pressure oil pipes. Carefully check whether the hydraulic oil is missing. According to the position of the oil plane of the hydraulic oil tank, check whether the high-pressure oil pipe is aging. The high-pressure oil pipe is often exposed to the outside and is easy to age. Once the oil pipe is aged, the high-pressure oil pipe may burst, causing the lift to drop suddenly, and finally causing danger! Then check whether the connection of each movable joint of the lift is normal. If it is loose, it must be tightened immediately with tools.

The Difference Between Sewage Suction Truck And Fecal Suction Truck

The tank of the fecal suction truck is oval, usually made of carbon steel or stainless steel. It is mainly used to pump manure, sewage, sludge and liquids mixed with small suspended debris. The truck has two modes: self-flow discharge and pressurized discharge. The tank of the fecal suction truck is fixed on the chassis of the car.

ISUZU Sewage suction truck

The tank of sewage suction truck is a round tank, and the tank body is also made of carbon steel or stainless steel. It is mainly used for sewers, rainwater wells, inspection wells, septic tanks and various large objects such as mud, silt, gravel, bricks and other materials in the ditch. The sewage suction truck has two modes: self-flow discharge and pressurized discharge. The rear part of the suction truck has a hemispherical cover, which can be opened by the hydraulic system, and can be directly discharged from the rear of the tank.

ISUZU vacuum truck

Due to the structure and shape of the tank, the vacuum and suction of the fecal suction truck are not as large as the sewage suction truck. The suction stroke of the fecal suction truck is ≥7m, and the suction stroke of the sewage suction truck is ≥10m. At the same time, the medium they absorb is different. The fecal suction truck can only extract the liquid with the suspended matter, and the sewage suction truck can basically extract the debris smaller than the diameter. Because the tank body is fixed on the car, only the pressure difference of the vacuum pump can be used to discharge the sewage or the pipe can be self-discharged; and the rear part of the tank of the suction truck can be opened, and the liquid lifting function is used, and the tank body is inclined and straight-lined. better. The sewage suction truck can complete all the work of the fecal suction truck, but some of the fecal suction trucks cannot be completed. In this way, everyone should have seen that the sewage suction truck has higher performance than the fecal suction truck, but its cost is much higher than that of the suction truck. In addition, the suction truck can be installed with sprinkler function according to customer requirements. The water and manure tanks can be divided into separate compartments, which can suck the feces and sprinkle water, and use one vehicle for both purposes. The sewage suction truck can generally be installed with a cleaning function, making it a high-pressure cleaning and suction-utilizing vehicle, commonly known as the “combined dredging vehicle”.
