Abstract
The invention discloses a stretching type air spring, which is provided with a piston cylinder and a piston, wherein the piston cylinder is divided into an oil gas mixing cylinder and a vacuum cylinder by the piston, one end, facing the oil gas mixing cylinder, of the piston is provided with a small piston rod, one end, facing a vacuum cylinder, of the piston is provided with a large piston rod, the piston, the small piston rod and the large piston rod are positioned on the same axial line, the piston is provided with a small hole, the small piston rod and the large piston rod are sheathed with guide rings, the guide rings are sealed, the end parts of the piston cylinder and the small piston rod are respectively provided with a joint, and inert gas is inflated into the oil gas mixing cylinder. The stretching type air spring can be widely applied to vehicle doors and train folding seats, safety and reliability are realized, and the application gap of the traditional compressed air springs are filled.
Description
Technical field
The present invention relates to a kind of air spring, refer more particularly to a kind of stretching air spring.
Background technique
Air spring is a kind of industrial accessory that can play the effects such as support, buffering, braking, principle is in airtight piston cylinder, to be filled with inert gas or gas mixture, make air pressure in cylinder higher than several times, barometric pressure or tens times, utilize the area difference of piston and piston rod to produce the motion that pressure difference realizes piston rod, with respect to common spring, have slowly mobile, easily control, can restorable advantage after long-time compressed or drawing.At present, domestic use is all compression type air spring.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of stretching air spring.
In order to solve the problems of the technologies described above, the invention provides a kind of stretching air spring, be provided with piston cylinder and piston, piston is divided into air-fuel mixture cylinder and vacuum reservoir by piston cylinder, described piston area is provided with small piston rod to air-fuel mixture cylinder one end, piston area is provided with large piston rod to vacuum reservoir one end, and piston, small piston rod, large piston rod are positioned on same shaft axis, and described piston is provided with aperture.
As a further improvement on the present invention, described small piston rod and large piston rod cover have guide collar, and guide collar seals.
As a further improvement on the present invention, described piston cylinder and small piston rod end are respectively equipped with a joint.
As a further improvement on the present invention, in described air-fuel mixture cylinder, be filled with inert gas.
Adopt said structure, its beneficial effect is: this stretching air spring can be widely used in car door, and jack knifing seat is safe and reliable, has made up the application vacancy of conventional compression formula air spring.
Accompanying drawing explanation
Fig. 1 is the structural representation of stretching air spring of the present invention.
In figure: 1-piston cylinder, 2-piston, 3-air-fuel mixture cylinder, 4-vacuum reservoir, 5-small piston rod, the large piston rod of 6-, 7-aperture, 8-guide collar, 9 joints.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
As shown in Figure 1, a kind of stretching air spring, be provided with piston cylinder 1 and piston 2, piston 2 is divided into air-fuel mixture cylinder 3 and vacuum reservoir 4 by piston cylinder 1, described piston 2 is provided with small piston rod 5 towards air-fuel mixture cylinder 3 one end, piston 2 is faced vacuum reservoir 4 one end and is provided with large piston rod 6, piston 2, small piston rod 5, large piston rod 6 is positioned on same shaft axis, described piston 2 is provided with aperture 7, described small piston rod 5 and large piston rod 6 covers have guide collar 8, guide collar 8 seals, described piston cylinder 1 and small piston rod 5 ends are respectively equipped with a joint 9, in described air-fuel mixture cylinder 3, be filled with inert gas.。
Stretching air spring is when concrete application, two end connectors should be fixed with external object respectively, when air spring receives that external force pulls, small piston rod 5 is drawn out outside deactivation plug cylinder 1, and simultaneously large piston rod 6 slowly enters in air-fuel mixture cylinder 3, because large piston rod 6 is larger than the diameter of small piston rod 5, so large piston rod 6 makes the inert gas in air-fuel mixture cylinder 3 compressed, produces pressure, once the external force of removing, air pressure can, by large piston rod 6 pushed home, restore to the original state.
This stretching air spring can be widely used in car door, and jack knifing seat is safe and reliable, has made up the application vacancy of conventional compression formula air spring.
Within the similar designed stretching air spring of technical characteristics of any employing and the present invention will fall into protection scope of the present invention.
