What is the function of a car's suspension?

[DiEsther]

The role of a car's suspension: to transmit forces and torque between the wheels and the frame, and to cushion the impact from uneven road surfaces transmitted to the frame or body, as well as to dampen the resulting vibrations, ensuring smooth driving. The suspension system is the general term for all force-transmitting connection devices between the car's frame and the axle or wheels. Modern car suspension systems are mostly ECAS systems, which are mainstream suspension systems from Europe. They utilize electronic control systems to significantly improve the performance of traditional air suspension systems, enabling the car to achieve active adjustment and control under various road conditions and operating conditions, while also adding many auxiliary functions.
