Product Description

New Invention trailer American Type Air Suspension capacity 13T

Product Application

The principle of the air suspension is to change the height of the vehicle by using an air compressor to form compressed air and sending the compressed air to the air chamber of the spring and the damper. A vehicle height sensor is arranged in the vicinity of the front wheel and the rear wheel. According to the output signal of the vehicle height sensor, the microcomputer determines the change of the height of the vehicle body, and then controls the compressor and the exhaust valve to compress or elongate the spring, thereby reducing The effect of the vibration. The air suspension gives the car more spirituality. When you are driving at high speed, the suspension can be hardened to improve the stability of the car body. When driving on low-speed uneven roads for a long time, the control unit will soften the suspension to improve the comfort of the car.


Since the birth of the air suspension in the mid-nineteenth century, it has undergone a century of development, and has experienced "pneumatic spring-airbag composite suspension→semi-active air suspension→central charge and discharge air suspension" and other variations. It was not used in trucks, buses, cars and rail cars until the 1950s. At present, almost all foreign advanced buses use air suspension, and the proportion of heavy-duty trucks using air suspension has reached more than 80%. The application of air suspension in light-duty vehicles is also rapidly increasing.

NOTE

Generally speaking, the contents of the air suspension control include the height of the vehicle body, the damping force of the damper, and the spring elasticity coefficient:

1. Control of the height of the car: substandard, elevated and only the rear wheel is raised;

2. The damping force of the damper is controlled by the third gear of low, medium and high;

3. The elastic coefficient of the air spring is divided into two parts: soft and hard.

Air suspension has an irreplaceable advantage over the conventional suspension. Therefore, with the popularization and improvement of this technology, it will inevitably be more widely used in the automotive industry in the future.

Interview

The vehicle with air-adjustable suspension will be equipped with a ground-distance distance sensor near the front and rear wheels. According to the output signal of the ground-distance sensor, the driving computer will judge the height change of the vehicle, and then control the air compressor and exhaust. The valve automatically compresses or elongates the spring to reduce or raise the ground clearance of the chassis to increase the stability of the high-speed body or the passage of complex road conditions. In daily adjustments, the air suspension will have several states. 


1. Maintain the status. When the vehicle is lifted by the lifter and leaves the ground, the air suspension system will close the relevant solenoid valve, and the computer will remember the height of the vehicle, so that the vehicle will maintain its original height after landing: 


2. The normal state, that is, the engine running state. During the driving process, if the height of the vehicle changes beyond a certain range, the air suspension system will adjust the height of the vehicle at intervals: 


3. Awakening state. When the air suspension system is awakened by the remote control key, the door switch or the trunk lid switch, the system checks the height of the vehicle through the body level sensor. If the height of the car is below a certain height, the tank will provide pressure to raise the car to normal height. At the same time, the air suspension can adjust the softness and hardness of the shock absorber, including soft state, normal and hard state (also marked as comfortable, normal, sports, etc.), the driver can use the control button inside the car control.

The sturcture of Suspension

Semi-Trailer suspension type
Leaf spring suspension
The leaf spring suspension (referred to as the leaf spring suspension) is divided into a small piece of variable section steel plate suspension and an equal section of multiple leaf spring suspension. At present, more than 95% of the heavy-duty suspension systems in China are non-independent suspensions with leaf springs as elastic elements and as guiding devices. The main advantages are simple structure, easy manufacture, convenient maintenance, mature technology and reliable operation.
Air suspension
The air suspension system uses an air spring as an elastic element and air as an elastic medium. In a sealed container, compressed air (pressure is 0.5~) is used, and the compressibility of the gas is utilized to achieve its elastic action. This spring has variable stiffness and desirable elastic properties.
At present, there are two main types of air suspension control modes, one is manual adjustment using a mechanical height valve. The other is Electronic Control (ECAS), which greatly improves the performance of the traditional air suspension system, improving the comfort of the suspension and the sensitivity of the reaction.
Rubber suspension
The rubber suspension is a rubber spring as an elastic element. Due to the variable stiffness of the rubber spring, the entire suspension has a strong load carrying capacity. The rubber suspension has advantages over the conventional steel plate suspension in terms of load bearing capacity and reliability, and can adapt to the harsh working conditions such as mining operations.
