Even on the most bumpy roads, the car can be driven smoothly

An adjustable suspension is a suspension whose performance can be adjusted according to road conditions and the driving state of the car.

Adjustable suspension, divided into active suspension and semi-active suspension. The fully active suspension can adjust the stiffness and damping of the suspension in a timely manner according to the motion state of the car and the road condition, so that it is in the optimal damping state. The semi-active suspension does not consider changing the stiffness of the suspension, but only considers the damping of the suspension.

The electromagnetic adjustable suspension refers to a suspension method that uses electromagnetic reaction to realize the height rise and fall of the automobile chassis. It can respond to road conditions, react within 1 millisecond, suppress vibration, and keep the body stable, especially when the speed is high and the obstacles are encountered. Its response speed is 5 times faster than conventional suspension, ensuring smooth running even on the most bumpy roads.

The electromagnetic suspension system is composed of a traveling computer, a wheel displacement sensor, an electromagnetic hydraulic rod and a straight damper. There is a wheel displacement sensor at each wheel and body connection, the sensor is connected to the driving computer, and the driving computer 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 liquid called a magnetorheological fluid, which is composed of synthetic hydrocarbons and tiny iron particles. In normal times, magnetic metal particles are scattered in the liquid and have no effect. If there is a magnetic field, they will be arranged in a certain structure, and the damping fluid will become a plastic-like state. The density of the damping fluid can be precisely controlled by controlling the current flow and is a timely and continuous control.
