Abstract
A self-adaptive damping adjustment diverter valve of a self-adaptive variable damper shock absorber for an automobile is simple in structure, low in cost, capable of being matched with the damping characteristic curve of a compression valve, reliable in performance and long in service life, wherein the damping characteristics change along with a pre-set change curve according to typical road conditions. An original normally through hole and butterfly valve type throttling valve is modified into a slide valve type throttling valve. An original normally through hole damping non-adjustable mode is changed into a pressure self-adaptive control and adjustment mode. The vibration frequency controlling the damping characteristics is replaced by static loads including inertia load, dynamic load and pulse load. Passive shock absorption is changed into positive shock prevention, accordingly the performance of the variable damper shock absorber is further improved, and another technical support is provided.
Description
One, technical field:
The present invention relates to the method and structure that a kind of automobile is regulated with the damping adaptive of adaptive damping vibration damper diverter valve.Be particularly useful for intermediate car and use vibration damper, also be applicable to the vibration damper that other vehicles and equipment are used.
Two, the state of the art:
In order to improve ride of vehicle, improve the travelling comfort of taking, Hyundai Motor has adopted hydraulic damper widely in its suspension system.On senior deluxe carmodel, also adopted the adaptive damping vibration damper.The adaptive damping vibration damper can be regulated damping automatically with load, condition of road surface, running speed, and the smoothness and the travelling comfort of more traditional immutable vibration damper of damping have had significant lifting.But; Existing adaptive damping vibration damper than mature technique in; People have only realized the damping of compression valve and rebound valve is regulated; The damping adjusting that is opposite to the diverter valve in the shock absorber body is then powerless, and it has still been adopted the structure and the processing method of traditional nonadjustable vibration damper of damping, the different just difference of inflation pressure.Because diverter valve is the functional element of the control vibration damper compression damping parallelly connected with compression valve; On the compression damping characteristic of regulating vibration damper, have and the almost equal effect of compression valve; So just make being adjusted in of smoothness and travelling comfort of vehicle of this series products be difficult in theory hold, also unsatisfactory in actual use.In order to satisfy the further requirement of people to travelling comfort, people have just carried out the research that the damping of diverter valve is regulated, and attempt through modulating valve being placed the external of vibration damper, and external adjusting damping improves this situation to vibration damper upper and lower cavity fluid through them.But, also can only rest on the field of scholastic pursuit so far owing to many difficulties of laying of external its line arrangement of valve class of regulating damping, control unit.Today, along with the improvement and the vehicle entering family of road conditions, people must have higher requirement to riding comfort.Will further improve the All-terrain smoothness that goes and the travelling comfort of taking of vehicle, research and development and innovation that the damping of the simple vibration damper diverter valve that is suitable for is regulated have just become inevitable choice.
Three, goal of the invention and solution:
The object of the invention will be researched and developed a kind of simple in structure exactly; Lower-cost; Drag characteristic is that the active that changes according to the change curve that typical road conditions are set in advance is shockproof, the method for its damping adjusting of the novel changable damping shock absorption device diverter valve of reliable performance and long service life.
Solution of the present invention is: vibration damper adaptive damping diverter valve is constituted by interior cylinder cap 1, flow divider valve core 2, spring 3, lowest compression force control valve core 4, spring 5, spring seat 6 etc.Form diverter valve by interior cylinder cap 1, flow divider valve core 2, spring 3, lowest compression force control valve core 4, spring seat 6; Form the lowest compression force control valve by flow divider valve core 2, lowest compression force control valve core 4, spring 5, spring seat 6 etc., lowest compressive force is decided by the sectional area of lowest compression force control valve core 4 and the rigidity and the decrement thereof of spring 5.When the pressure of vibration damper cavity of resorption force value greater than the lowest compressive force of setting; It acts on the spring force of making every effort to overcome clothes spring 5 on lowest compression force control valve core 4 upper end; Promoting lowest compression force control valve core 4 moves down; Until withstanding spring seat 6, all opened the normal open hole of leaning on the bottom on the flow divider valve core 2; And along with the increase of the pressure of vibration damper cavity of resorption, the power on the flow divider valve core 2 upper end annulus areas of acting on can promote it and move down, and has progressively turned down the normal open hole again, makes it to adapt with the load of vehicle; When the dynamic load increase of vehicle, the pressure step of vibration damper cavity of resorption can promptly promote flow divider valve core 2 and move down, and has opened the throttling pore on its top, promptly reduces the compression damping of vibration damper, reduces the impact of road surface projection to vehicle.
So; Just the damping of diverter valve in the existing adjustable damping technology is regulated and carried out revolution completely; Feasible damping to diverter valve is regulated and is become controlled target; And can mate with the damping characteristic of compression valve, the collecting treatment mode of its control signal is more direct, easy, reliable, no conversion links; The control mode reaction is fast, stable.Thereby be the performance that further improves the adaptive damping vibration damper, smoothness and the travelling comfort of further improving vehicle provide technical support.
Four, description of drawings:
Accompanying drawing 1 is a structure principle chart of the present invention.
Five, mode of execution:
Embodiment of the present invention is: after the load of vehicle increases; As long as vehicle start, the pressure of shock absorber piston cavity of resorption raises, and has broken the balance of lowest compression force control valve core 4; Promote its pressure spring 5 and move, opened the normal open hole of leaning on its underpart on the flow divider valve core 2; And the further rising of cavity pressure under shock absorber piston; It has promoted flow divider valve core 2 and has moved down; Again progressively turned down the normal open hole of flow divider valve core 2 on leaning on its underpart because lowest compression force control valve core 4 is spacing by spring seat 6 this moment, and the load that makes its opening of technetium and vehicle is to adaptation.Run into projection when vehicle being in operation, its dynamic load increases, and the pressure step of vibration damper cavity of resorption promptly promotes flow divider valve core 2 and moves down, and has opened the throttling pore on its top, promptly reduces the compression damping of vibration damper, reduces the impact of road surface projection to vehicle.
