Description
Technical field
The present invention relates to a kind of formation structure and method of work of dual spindle gas spring, belong to air spring and make the field.
Background technique
Publication number CN1975194A, title " air spring ", it is between main elasticity air cavity that piston body separation cylinder block forms and secondary elasticity air cavity the air compression system that the damping air flue constitutes sealing to be set, utilize of the damping force effect of damping air flue to medium, make in main elasticity air cavity and the secondary elasticity air cavity and have the gas pressure intensity that does not wait, when piston body was moved up and down by the external force effect to be air spring externally to show as compression or elongation, it can come balance to adapt to the effect of external force by regulate its stiffness variation automatically near the optimum condition of " real-time ".Its deficiency: can only unidirectional elongation or compression.
Summary of the invention
Purpose of design: avoid the deficiency in the background technique, design a kind of can either unidirectionally stretching, dual spindle gas spring and method of work that again can bi-directional expansion.
Design proposal: in order to realize above-mentioned purpose of design.The present invention one is that utilization changes face compression area about piston and produces pressure difference, and piston is moved to the left or to the right, is major technique feature of the present invention.The purpose of doing like this is: because cylinder block is divided into left chamber and right chamber, pressed gas or liquid are housed respectively in it, the aperture on the piston communicates left chamber and right chamber, and unit plane overstocks identical.When the aperture on the rotating sleeve communicated with axle I, left cavity pressure area increased, and the total pressure that promptly acts on the piston gross area increases, and piston moves right; Otherwise piston is moved to the left.Logical or obstructed by the left-right rotation cover with the axle upper groove, change pressure area, thereby finish the function of move left and right; The 2nd, can realize the bi-directional expansion air spring to the present invention, a kind of be about portion can outwards stretch simultaneously and move or move to compression simultaneously, another kind is also can be asynchronous.
Technological scheme 1: the cylinder block of dual spindle gas spring is a left and right sides cavity, have the perforation aperture on the piston in the cavity of the left and right sides, about two axle one ends pass respectively that axis hole in the left and right sides end cap of cylinder block is connected with an end face of left and right sides piston respectively and the axostylus axostyle of Y-axis on have groove, about two axle rotating sleeves be enclosed within on the Y-axis respectively and the Y-axis rotating sleeve has aperture.
Technological scheme 2: the method for work of dual spindle gas spring, the cylinder block of dual spindle gas spring is a left and right sides cavity, have the perforation aperture on the piston in the cavity of the left and right sides, about two axle one ends pass respectively that axis hole in the left and right sides end cap of cylinder block is connected with an end face of left and right sides piston respectively and the axostylus axostyle of Y-axis on have groove, about two axle rotating sleeves be enclosed within on the Y-axis respectively and the Y-axis rotating sleeve has aperture; (1) left and right sides working state of left chamber piston, aperture on rotation air-cored axis rotating sleeve aligns with the groove in the air-cored axis, this moment is owing to the area of the piston left side, left chamber area greater than the right, chamber, left side piston is under the effect of left chamber hydrodynamic pressure, driving left chamber piston moves right, chamber, left side piston drives air-cored axis and moves right, otherwise, when aperture on rotating air-cored axis's rotating sleeve and air-cored axis are sealing state, this moment is owing to the area of the piston left side, left chamber area less than the right, chamber, left side piston drives left chamber piston and is moved to the left under the effect of left chamber hydrodynamic pressure, and left chamber piston drives air-cored axis and is moved to the left; (2) left and right sides working state of right chamber piston, when the aperture on the rotatingshaft rotating sleeve with the axle on groove align, this moment is owing to the area of right chamber piston the right area greater than the left side, right chamber piston is under the effect of right chamber hydrodynamic pressure, driving right chamber piston is moved to the left, right chamber piston drives and axially moves left, otherwise, when the aperture on the rotatingshaft rotating sleeve is sealing state with axle, this moment is owing to the area of right chamber piston the right area less than the left side, right chamber piston drives right chamber piston and moves right under the effect of right chamber hydrodynamic pressure, and right chamber piston drives and axially moves right.
The present invention compares with background technique, and the one, realized that not only air spring is unidirectional flexible, and realized the bi-directional expansion of air spring; The 2nd, structural design novelty, uniqueness, simple, practical.
