Problems solved by technology

[0003] Under the current technology, although the application of air springs with additional air chambers is becoming more and more extensive and mature, in many cases, a single air spring cannot meet the requirements of the entire vibration damping system
The patent application number is 201310235464.6, and the name is an additional air chamber with adjustable volume. Although an additional air chamber with adjustable volume is proposed, this additional air chamber can only be used by one air spring, and it cannot Real-time control according to the working condition of the air spring

Embodiment Construction

[0033] see figure 1 , the double air spring with shared additional air chamber in this embodiment includes left air spring 7A and right air spring 7B, and shared additional air chamber 9 is set between said left air spring 7A and right air spring 7B and is used for controlling A controller 21 for the working mode of the additional gas chamber 9 .

[0034] like figure 1 As shown, the left main air chamber 1A in the left air spring 7A is sealed by a hyperbolic left rubber bag 6A fixedly connected to the left upper cover 2A at the top and fixedly connected to the left lower cover 3A at the bottom through the left fixed connection device 4A. The air chamber is provided with a left waist ring 5A at the waist of the left rubber bag 6A in a hyperbolic shape, which is used to limit the radial expansion of the waist of the left rubber bag 6A and prevent mutual friction between the hyperbolas; the left lower cover plate 3A The center of the left hose 8A communicates with the left m...

Abstract

The invention discloses a dual air spring with a shared additional air chamber and a control method and application of the dual air spring. The dual air spring is characterized in that the dual air spring comprises a left air spring body and a right air spring body, and the shared additional air chamber and a controller used for controlling the working mode of the shared additional air chamber are arranged between the left air spring body and the right air spring body. The occupied space of the dual air spring is effectively reduced through the shared additional air chamber, the rigidity of the dual air spring can be controlled in real time according to the load displacement working condition of the air spring and the running work condition of an automobile, and the damping effect of the air spring is improved.

Description

technical field [0001] The present invention relates to an air spring, and more particularly relates to a double air spring with a shared additional air chamber and a control method thereof. Background technique [0002] As a non-metallic elastic element composed of a rubber bag with ply inside and compressed gas filled into the inner cavity of the rubber bag, the air spring has better vibration damping performance than the metal elastic element. It is used in automobiles, rail transit, Widely used in industrial machinery and other fields. Zhang Liguo mentioned in "The Current Situation and Development of Air Springs" that air springs have low stiffness and can exhibit nonlinear self-regulation as the load changes, so that the natural frequency of the entire damping system is low and basically unchanged. The air spring also has the advantages of adjustable height, light weight, low noise, and long service life. The stiffness of an air spring depends on its volume, effectiv...
