The shock - damping principle of the New OEM Tesla Model S Air Shock Absorber Strut Front 2016 - 2021 Without Fork Arms 1067361 - 77 - C is as follows:
Based on Gas Compressibility7: This is an air - type shock absorber strut. It utilizes the compressibility of gas to absorb shock energy. Inside the strut, there is a sealed air chamber filled with high - pressure gas, usually nitrogen. When the wheel moves up and down due to uneven roads, the motion is transmitted to the air chamber through the piston rod. The high - pressure gas in the air chamber is compressed or expanded, converting the kinetic energy of the suspension's motion into the internal energy of the compressed air, thus absorbing and buffering the impact force from the road.
Damping Regulation by Piston and Orifices2: Similar to hydraulic shock absorbers, air shock absorbers also have a piston structure. There are small holes on the piston. When the piston moves up and down in the pressure cylinder, the gas (or the mixed gas and oil in some designs) will pass through these small holes. Due to the small size of the holes, only a small amount of gas can pass through under high pressure, which slows down the movement speed of the piston, and then slows down the movement of the spring, achieving the purpose of shock absorption.
Adaptive Adjustment According to Road Conditions: Modern shock absorbers have a speed - sensing function, and this air shock absorber strut is no exception. The faster the suspension moves, the greater the resistance provided by the shock absorber. When the vehicle is driving on a rough road, the suspension movement is intense, and the shock absorber will quickly increase the resistance, effectively suppressing the vehicle's bounce, roll, dive and other movements, so as to ensure driving stability and comfort.
Collaboration with Airbag: In the Tesla Model S air suspension system, the shock absorber strut works in conjunction with the airbag. The airbag can adjust the suspension height and hardness by inflating and deflating. When encountering a bumpy road, the airbag inflates rapidly to increase the suspension hardness, and the shock absorber strut absorbs and disperses the impact force at the same time, reducing the vehicle's vibration. On a flat road, the airbag deflates appropriately, and the shock absorber strut also adjusts the damping to make the driving more comfortable.
