Description
Technical field
The utility model is related to gas spring technology fields, more particularly to a kind of steady type gas spring gas bar.
Background technology
In rolling stock, it is disposed with gas spring between vehicle body and vehicle frame, is applied to be reduced during vehicle is advanced
The shock and vibration of car body are added on, however can be shaken to all directions in vehicle travel process, when vehicle load is excessive, gas bar
It is easy to suffer oppression and leads to flexural deformation, influence gas spring service life.
In the prior art, by improving gas spring specification, thickening gas bar, to reach distortion-free purpose, however gas bar adds
Work requires more precision, production cost excessive.
Utility model content
Technical problem to be solved in the utility model is：In order to overcome deficiency in the prior art, the utility model to carry
For a kind of steady type gas spring gas bar.
The utility model solves its technical problem technical solution to be taken：A kind of steady type gas spring gas bar,
Component is consolidated including gas bar body and on the ontology, described ontology one end is equipped with piston, and the ontology passes through piston
It is slidably connected with gas spring inner wall of cylinder face, the firm component includes terminal pad and two firm blocks, and the terminal pad is set to
Side of the ontology far from the piston, the terminal pad are coaxially disposed with the ontology, and the terminal pad is circumferentially uniform
If there are two sliding slot, the sliding slot is radially arranged along the terminal pad, and the terminal pad is taper close to one end of the piston
Face, two firm blocks are oppositely arranged to form firm ring set on the ontology, the firm ring internal face with described
Body sidewall coordinates, and multiple elastic rings, two firm blocks are arranged in the firm ring outside wall surface of two firm block compositions
Coordinate close to one end of the terminal pad and the taper surface of the terminal pad, is respectively equipped with and the cunning on two firm blocks
The slide bar of slot cooperation, two firm blocks are fixedly connected on by bolt and slide bar cooperation in the terminal pad, two
The firm block is close to one end of piston to inward side to inclined inclined-plane.
With cylinder barrel with gas spring is combined into, gas bar body is slidably connected gas bar body by piston and inner wall of cylinder face, even
Disk is connect for connecting on the body firm block, firm block forms firm ring under the action of elastic ring and coordinates with this body sidewall,
Play a supportive role to ontology, prevent ontology from being influenced to occur bending and deformation by ambient pressure, gas spring shrink when, slide bar along sliding slot to
Slided far from body axis direction, firm block is moved to along inclined-plane on cylinder barrel lateral wall, when gas spring is stretched out, bolt band moving slide-bar from
And drive and consolidate block to being moved far from cylinder barrel direction, firm block is contracted under the action of elastic ring on ontology.
Further, block is consolidated when shrinking in order to facilitate gas spring to move in cylinder barrel outside wall surface, the cylinder barrel is close to the company
The one end for connecing disk is taper surface.
The utility model has the beneficial effects that：A kind of steady type gas spring gas bar provided by the utility model, using this
Firm block is set on body and forms firm ring, main body Auxiliary support is acted on when ontology stretches out cylinder barrel, prevents ontology by the external world
Pressure influence occurs bending and deformation, and influences gas spring service life.
