It is believed that you will not be unfamiliar with the word "air suspension" when you hear about trailer accessories. The future semi trailers will use air suspension. Today, I will give you a brief explanation of the advantages and disadvantages of air suspension, which will also facilitate you to choose a better semi-trailer in the future. Air reservoir series - the working principle of air suspension is to use air compressor to form compressed air and send it to the air chamber of spring and shock absorber to change the height of the vehicle. The height sensor is set near the front wheel and rear wheel. According to the output signal of the height sensor, the microcomputer judges the change of body height, and then controls the compressor and exhaust valve to compress or extend the spring, so as to reduce vibration. Trailer suspension accessories Air suspension gives the car more flexibility. When you drive at high speed, the suspension can be hardened to improve the stability of the body; When driving on uneven roads at low speeds for a long time, the control unit will soften the suspension to improve the comfort of the car. Generally speaking, air suspension control includes three items: body height, damping force of shock absorber, spring elasticity coefficient, etc.:
The trailer suspension parts are much lighter than the traditional leaf spring suspension. One of the biggest advantages of air suspension is its light weight. This is also an important reason for ordinary users to pay attention to air suspension. At present, under the premise of charging by weight, air suspension has obvious advantages in lightweight.
More attention should be paid to the fact that vehicles with air suspension can drive more smoothly. The elastic coefficient of the air spring is that the soft and hard parts can be automatically adjusted according to the needs, which is lighter than the weight. When the vehicle is running at a high speed, the air spring becomes hard to improve the stability of the vehicle. When encountering poor road conditions, the air spring becomes soft to improve the comfort of the vehicle. The adjustment of the air spring can also ensure the constant height of the trunk, which is conducive to protecting the safety of goods
The trailer accessories can lift the axle through air suspension, which can be raised and lowered in two aspects. The air reservoir series is conducive to reducing tire wear and saving fuel, especially suitable for the working condition with unilateral venting. Convenient for loading and unloading goods. The height of vehicle loading platform can be reduced to a certain extent by air suspension. However, this kind of chassis has good stability and handling. Disadvantages: there is no certain standard for sports chassis. It can be simply interpreted as good sportiness, but the comfort of sports chassis is generally poor
