Group 1 - The core component of a vehicle's suspension system is the shock absorber, which significantly influences driving characteristics and safety by adjusting damping force to enhance ride quality and reduce vibrations [1][2] - Shock absorbers are crucial for maintaining vehicle stability, ensuring tire grip, and improving cornering performance, braking, and steering [2][3] - The most commonly used type of shock absorber is the hydraulic cylinder type, which can be classified based on various criteria such as the number of cylinders, stroke type, and whether the damping is adjustable [3][5] Group 2 - The working principle of shock absorbers involves the movement of a piston within a cylinder, where hydraulic fluid is forced through valves to create damping force that mitigates vehicle vibrations [3][5][7] - Traditional shock absorbers have fixed valves, limiting the ability to adjust damping characteristics, while continuously variable damping control incorporates electronic control to adjust damping force in real-time based on driving conditions [8][10] - The advantages of continuously variable damping include strong adaptability to road conditions, enhanced safety through rapid damping adjustments, and improved comfort by reducing vibrations and noise transmitted to the cabin [12] Group 3 - Most market offerings of continuously variable damping shock absorbers utilize a single valve structure, which can limit the independent adjustment of rebound and compression damping [15] - The dual-valve damping system, which employs two independent valves for rebound and compression, allows for a broader adjustment range and faster response, enhancing ride comfort and stability [15][18] - An example of this technology is seen in the Audi Q3, where the dual-valve shock absorber optimizes damping during uneven road conditions, improving overall driving experience [18]
