Compared with traditional steel car suspension systems, air suspension has many advantages. The most important point is that the spring's spring constant is the spring's soft and hard energy can be adjusted automatically according to needs. For example, the suspension can be hardened at high speed to improve the stability of the vehicle. When driving at low speed for a long time, the control unit thinks that it is passing through the bumpy road, and the suspension is softened to improve the shock absorption comfort.
In addition, the acceleration generated by the impact of the wheel on the ground is also one of the parameters considered when the air spring is automatically adjusted. For example, at high speed cornering, the air springs and shock absorbers of the outer wheel will automatically harden to reduce the roll of the body. The electronic module will also strengthen the spring and shock absorber hardness of the front wheel during emergency braking. To reduce the inertia of the body forward. Therefore, models equipped with air springs have higher control limits and comfort than other vehicles.
A new type of independent suspension system that utilizes electromagnetic response, which can respond to road conditions and react within 1 millisecond, suppress vibration and maintain stability of the vehicle body, especially when the vehicle speed is high and sudden obstacles are displayed. . Its response speed is 5 times faster than conventional suspension, ensuring smooth running even on the most bumpy roads.
The electromagnetic suspension system consists of an on-board control system, a wheel displacement sensor, an electromagnetic hydraulic rod and a straight shock absorber. There is a wheel displacement sensor at each wheel and body connection, the sensor is connected to the onboard control system, and the control system is connected to the electromagnetic hydraulic rod and the straight damper.
The straight damper is different from the traditional hydraulic damper. It has no small valve structure and does not achieve the purpose of damping by the flow resistance of the liquid. There is also a damping fluid in the electromagnetic damper, but it is a special fluid called electromagnetic fluid (Magneto-rheological Fluid) composed of synthetic hydrocarbons and tiny iron particles.
