Abstract

The invention discloses a barrel-type air spring. The barrel-type air spring comprises an air cylinder and a piston assembly arranged in the air cylinder, and the piston assembly comprises a piston rod and a piston; the piston is used for separating the air cylinder into a vibration reduction working cylinder and a spring working cylinder, and the interior of the piston rod is a cavity which is avibration reduction air storage cavity; the vibration reduction air storage cavity communicates with the vibration reduction working cylinder, a vibration reduction valve body is arranged between thevibration reduction working cylinder and the vibration reduction air storage cavity, the vibration reduction valve body is further provided with a vibration reduction throttling hole, and the vibration reduction throttling hole is used for enabling the vibration reduction working cylinder to communicate with the vibration reduction air storage cavity; the spring working cylinder communicates witha spring air storage cavity, an air spring valve body is arranged between the spring working cylinder and the spring air storage cavity, and an air spring throttling hole is formed in the air spring valve body and enables the spring working cylinder to communicate with the spring air storage cavity. The barrel-type air spring is simple in structure, safe and reliable; high-pressure air filling equipment and a filling pipeline are not needed, the layout of a chassis is simplified, the space is saved, and the influence of environmental factors is small.

Description

technical field [0001] The invention relates to an automobile suspension, in particular to a cylindrical air spring. Background technique [0002] As we all know, automobile suspension can reduce the vibration and impact that the automobile receives during driving, so that the automobile can drive more safely and comfortably; automobile suspension is widely used in automobiles. The suspension for riding a bicycle includes damping elements and elastic elements, and the elastic elements of the existing automobile suspension are usually leaf springs and air springs; the stiffness and weight of the leaf springs in the existing elastic elements are relatively large, which increases the overall weight of the vehicle body. [0003] In existing commercial vehicles, air springs are usually used, and the air springs are composed of rubber bladders and high-pressure gas filling equipment. The rubber bladder has limited rigidity, is easily damaged, is greatly affected by environmental ...
