[0002] With the progress of society and economic development, consumers have higher and higher requirements for vehicle riding comfort. Traditional products are upgraded to meet market demand, especially buses using traditional leaf spring suspensions, which are criticized for their ride comfort. Under this premise, many automobile manufacturers have begun the research and development of air suspensions. Air suspension systems generally include: air springs, guide mechanisms, shock absorber damping mechanisms, lateral stability structures, and control mechanisms. It is particularly important to arrange the air suspension structure in a limited space.

[0003] The lateral thrust rod of a traditional automobile air suspension is usually rigidly connected to the vehicle body.
