Abstract

The invention relates to an air spring. The air spring comprises an upper cover plate, a base, an air bag and an auxiliary rubber spring, wherein the air bag and the auxiliary rubber spring are arranged between the upper cover plate and the base. A vertical through channel is formed in the central axis of the air spring, and a hanging column used for limiting is arranged in the through channel. A fixed cover component is arranged in the center of the upper cover plate and comprises an upper fixed end located in the center of the upper cover plate and an inner cylinder end located in the through channel. The upper end of the hanging column is installed in the inner cylinder end of the fixed cover component and connected with the fixed cover component. The lower end of the hanging column extends to the end, connected with the base, of the auxiliary rubber spring. According to the air spring, a traditional air spring structure is improved, a limiting mechanism is arranged in the air spring, the air spring has the function of vertically lifting a bogie, and the limiting function in the vertical direction is fulfilled in the air spring.

Description

technical field [0001] The invention belongs to the field of shock absorbing devices, in particular to an air spring. Background technique [0002] The air spring is installed between the car body and the bogie, as a shock absorber between the car body and the bogie, it plays the role of transmitting vertical load, lateral load and torque, absorbing vertical and horizontal vibration, and providing horizontal restoring force , has a great influence on the stability and comfort of railway vehicles. The structure of the traditional air spring mainly consists of an upper cover plate, an air bag and an auxiliary rubber spring. The upper cover plate is connected to the car body, and the base is connected to the bogie. The bogie is raised, and the air springs are responsible for damping the vibration between the car body and the bogie. [0003] For example, a kind of air spring and vehicle of patent CN210284226U, it is a typical air spring structure, and its structure is as figu...
