Embodiment 1

[0019] A sealing device for the upper mouth of a rubber air spring rubber airbag, comprising an upper cover plate 9, a friction plate 15, and a rubber airbag 10. The upper mouth 11 of the rubber airbag 10 is sandwiched between the upper cover plate 9 and the friction plate 10 In the middle, the upper sub-mouth 11 of the rubber airbag 10 is in the shape of a unilateral cone; on the upper cover plate 1, there is a groove-shaped notch 12 for installing the upper sub-mouth 11 of the rubber airbag 10, and the fastener is passed in the groove-shaped notch 12 13 is equipped with a boss 14, and a gap in the shape of a "7" is formed by the groove-shaped notch 12 and the boss 14; on the friction plate 15, there is also a gap 16 for installing the upper sub-mouth 11 of the rubber air bag 10, and the friction plate The notch 16 on 15 is a unilateral conical notch close to the outer circle; the "7" notch formed by the groove-shaped notch 12 of the upper cover plate 9 and the boss 14 is comb...

Abstract

The invention relates to a sealing way of the tire bead on an air spring and a device thereof; the tire bead of a rubber balloon is placed in a tire bead groove which is formed by the combination of an upper cover plate and a friction plate; the tire bead of the rubber balloon is placed in the tire bead groove which is formed by the upper cover plate and the friction plate; and then sealing for the tire bead of the rubber balloon is formed by the joint compression of the upper cover plate and the friction plate. The sealing structure for the tire bead of the rubber balloon is as follows: a groove-shaped gap is arranged on the upper cover plate; a cone-shaped gap is also arranged on the friction plate; the groove-shaped gap on the upper cover plate is combined with the gap on the friction plate to form a cone-shaped cavity with an opening at one edge; the upper cover plate and the friction plate are connected together by a fastener. The tire bead of the rubber balloon is placed in the cone-shaped cavity; the side edge of the rubber balloon is lead out from the side edge opening of the cone-shaped cavity; and the rubber balloon extends outwards from the center by the opening.

Description

technical field [0001] The invention relates to a sealing method and a device of an air spring, in particular to a sealing method and a device of a slit rubber capsule on an air spring. It is mainly used for the sealing of rubber air springs in rail transit. Background technique [0002] In high-speed trains and urban subway light rail vehicles, air springs have been widely used. In these existing air springs, the connection between the airbag and the upper cover can be divided into two methods, self-sealing and bolt fastening. The main principle of the self-sealing method is to form an interference fit between the air bag and the conical mating surface of the upper cover plate through internal pressure (see attached figure 1 ), its advantage is that it is easy to assemble, and it can realize a large lateral displacement of the air spring system with a small perimeter of the airbag section. disengage. The bolt fastening method is to press the airbag tightly on the upper c...
