Embodiment 1

[0025] refer to figure 1 and figure 2 , an air spring damping device, comprising a base connecting plate 1, an air spring body 2, a shock absorbing screw 3 and a top connecting plate 4; several connecting pieces 11 are fixed on the base connecting plate 1 and the top connecting plate 4, the connecting pieces 11. The connecting screw can be selected, and the air spring damping device can be assembled in the related equipment through the connection between the nut and the connecting screw; Screw holes and a damping screw rod 3 form a screw pair; the outer rings of n bearings 41 are fixed with the top connecting plate 4, and the inner rings of n bearings 41 are fixed with n damping screw rods 3 respectively.

Embodiment 2

[0027] This embodiment is limited on the basis of Embodiment 1. The air spring body 2 includes a bottom end seal plate 21, an air flexure 22 and a top end seal 24; the bottom end seal 21 is fixed to the base connecting plate 1; several air flexures 22 are provided, and two adjacent air flexures 22 communicates through the waist ring 23, the air flexure 22 closest to the bottom end seal 21 is glued to the bottom end seal 21, and the air flexure 22 closest to the top end seal 24 is glued to the top end seal 24. The n screw holes that form the helical pair with the n damping screw rods 3 are all opened on the top end sealing plate 24 .

Embodiment 3

[0029] This embodiment is limited on the basis of the second embodiment. The inner layer of the air bellows 22 is made of high-air-tightness rubber, and the outer layer is made of medium-resistant and aging-resistant rubber.

Abstract

The invention discloses an air spring damping device and a damping method of the air spring damping device. An existing air spring body has a large self-vibrating area. The air spring damping device comprises a base connecting plate, an air spring body, a damping lead screw and a top connecting plate. A plurality of connecting pieces are fixed to the base connecting plate and the top connecting plate. One end of the air spring body is fixed to the base connecting plate. The other end of the air spring body is provided with screw holes with the quantity of n. Each screw hole and one damping lead screw form a spiral pair. Outer rings of bearings with the quantity of n are fixed to the top connecting plate. Inner rings of the bearings with the quantity of n are fixed to the damping lead screws correspondingly. According to the air spring damping device and the damping method of the air spring damping device, the air spring body is limited in a threaded connection mode by the damping leadscrew. When the air spring body self-vibrates, sliding only happens on the damping lead screw, so that vibration in the direction perpendicular to the damping lead screw is limited, and the self-vibration area of an air spring is reduced.

Description

technical field [0001] The invention relates to an air spring device, in particular to an air spring damping device and a damping method thereof. Background technique [0002] The air spring is filled with compressed air in a sealed container, and uses the compressibility of the gas to realize its elastic effect. The problem with the air spring is that when the air spring body realizes its elastic function, it will also have a self-vibration situation; Damage the internal parts of the equipment and cause unnecessary losses. Contents of the invention [0003] The object of the present invention is to propose an air spring damping device and a damping method thereof for the problem that the excessively large natural vibration area of ​​the air spring may cause damage to the inside of the equipment. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] An air spring damping device of the present invention co...
