摘要

悬架是现代汽车的重要总成之一，它把车价和车轴弹性地结合连接起来。主要任务是传递作用在车轮和车架之间的一切力和力矩；缓和路面传给车架的冲击载荷，衰减由此引起的承载系统的振动，保证汽车的行驶平顺性；保证车轮在路面不平和载荷变化时有理想的运动特性，保证汽车的操纵稳定性，使汽车获得高速行驶能力。

悬架由弹性元件、导向装置、减震器、缓冲块和横向稳定器等组成，囊式空气弹簧是弹性元件其中一种，它含有帘布层结构的橡胶气囊内冲入空气，并以空气为介质，利用空气可以压缩的特点来实现弹性作用。通过高度控制阀，来保证车身高度不随汽车载荷变化而变化，保证汽车的平顺性和稳定性。

 Abstract

Modern automobile suspension is one of the important assembly line and axle, it connects with flexibility. Main task is to transfer function between the wheel and frame of all the force and moment, To ease the impact load road frame, the attenuation caused by the vibration, guarantee system of bearing of vehicle, Ensure the road wheels rough and load changes have ideal characteristics, cars, cars won maneuvering high-speed capability.

Suspension of elastic component, guiding device, shock absorber, transverse stabilizer blocks and a buffer, cystic components, such as air spring flexible components, it contains one layer structure of air curtain inside irruptive air, rubber and air as medium, the characteristics of air can be compressed to achieve flexibility. Through the height valve body height, to ensure that no changes with the automobile loading, guarantee the stability and car ride.

Key words: Suspension, Capsule type air spring, Shock absorber, height control valve
