Abstract
The invention relates to a relative stiffness locked non- floating piston air spring, and relates to the technical field of air springs. The purpose of the air spring provided by the invention is that an air chamber of the air spring is filled with oils firstly, and then compressing nitrogen is introduced in; the air spring provided by the invention has the advantages that the air chamber is filled with relative adequate oils, the floating piston is not need, then the compressing nitrogen is filled, and an air cavity is relatively smaller; and the locking effect can basically reach the rigid locking, and the resistance is also smaller.
Description
Technical field
The present invention relates to the air spring production technical field.
Background technique
Press latching force characteristic difference from existing controllable type air spring, be divided into flexible locking (gas) and rigid locking (liquid).
Flexibility is locked as a spot of oil and compressed nitrogen mixes, and in same gas stops up, because of gas compressibility, after locking this moment, can produce big displacement under external force.
Rigid locking is separated state (it being separated with floating piston) for oily and compressed nitrogen are in, its shortcoming is: installation dimension is defined within the specific limits, corresponding gas chamber volume can be accomplished very little, when requiring internal pressure big, to cause the increase (resistance increasing) of compressive force value, not reach the state that needs.
Summary of the invention
The object of the invention is first extending oil in the air chamber of described air spring, adds compressed nitrogen then.
In described air chamber, oil volume percentage is 80～90%, and the percent by volume of compressed nitrogen is 10～20%.
The present invention gives and adds enough relatively oil (leaving air cavity in a small amount) in the air chamber, need not floating piston, charges into compressed nitrogen again, and less relatively because of its air cavity, its locking effect can reach rigid locking substantially, and resistance is also less.
Embodiment
When making air spring, in air chamber, fill 80%～90% oil of air chamber total volume amount earlier earlier, and then charge into 10%～20% compressed nitrogen.
Claims (2)
1. the no floating piston air spring with relative rigidity locking is characterized in that first extending oil in the air chamber of described air spring, charges into compressed nitrogen then.
2. according to the described no floating piston air spring with relative rigidity locking of claim 1, it is characterized in that in described air chamber oil volume percentage is 80～90%, the percent by volume of compressed nitrogen is 10～20%.
