AI Technical Summary
Existing air suspension systems for buses are heavy and bulky, which increases the space occupied during installation, increases the additional torque, reduces the stability and strength of the vehicle body, and has insufficient roll stiffness, affecting high-speed stability and handling.
The vehicle employs an integrated front air suspension system, including a balancing mechanism, a fixing mechanism, and shock absorbers. Through a compact structural layout, it uses longitudinal thrust rods, lateral thrust rods, and stabilizing components to increase structural stability. The balancing mechanism provides frame balance, air springs and shock absorbers buffer vibrations, and a hydraulic damping system enhances vehicle stability.
It improves the stability and handling of the suspension structure, reduces the probability of vehicle roll, enhances vehicle stability and safety, and optimizes vehicle adaptability and fuel economy.
