Description

Elastic shock absorbing structure for vehicle

Technical field

The present invention relates to a kind of shock absorbing apparatus, relate in particular to a kind of elastic shock absorbing structure for vehicle.

Background technology

Automobile is a walking-replacing tool indispensable during the modern lives.Though automobile provides people operation function easily; But its in-to-in machinery and Power Component wear and tear damage because of long-term use unavoidably gradually; When especially automobile runs quickly on road; Uneven road surface and hole, hole make the garage through the time generation amplitude vibrations of differing in size, this causes cooresponding distortion and wearing and tearing unavoidably to the machine elements in the running in the automobile, and significantly influences the car opertion life-span; And vibratory sensation also makes the passenger not feel well, so none is not is not researching and developing the more dynamical automobile anti-vibration structure of tool in the auto manufacturing;

Existing automobile anti-vibration structure sees also the TaiWan, China number of patent application No. 94210517; " structure-improved of automobile damper " patent; Its structure comprises a shock-absorbing axis body, and these shock-absorbing axis body two end book office groups are provided with upper fixed seat and lower seat, and cover is organized an elastic body between this upper fixed seat and lower seat; It is characterized in that: between these elastic body two ends and this upper fixed seat and the lower seat; Be equipped with a pad respectively, the outer surface cloth that these pads contact with this upper fixed seat and lower seat is provided with the lines of protrusion, bears vibrations external force and when being the damping state of compression when this elastic body whereby; Can reduce the friction contact coefficient between this pad and this upper fixed seat and lower seat, and can promote the smooth degree of shock-absorbing action and avoid noise.

Yet; Though the existing automobile anti-vibration structure of this kind can provide the effect of shock-absorbing, its only flexible body has the function of the vibrations of bearing, and does not have other assembly and can share the shock momentum that elastic body is loaded; Cause this elastic body to be prone to produce elastic fatigue, make significantly reduce its service life; In addition; Because this elastic body is the member that mainly bears vibrations; Therefore elastic body must use elasticity modulus and the higher material of rigidity to process; But the garage is the thing of moment through the vibrations that uneven ground produced, and the elastic body of the high rigidity of this kind because of its material so and absorbing vibration at once, therefore make anti-vibration structure and wheel junction take place impaired easily even rupture; Moreover; There is the dealer to have the effect that height rigidity and suitable flexibility are born quick vibrations with seasonal elastic body; Therefore must adopt material special and that price is higher to process elastic body; Cause manufacturing cost greatly to improve, so its poor practicability, but be necessary to research and develop the automobile anti-vibration structure that elastomer-assisted is shared the load shock momentum.

Summary of the invention

Technical problem underlying to be solved by this invention is, overcomes the above-mentioned defective that prior art exists, and a kind of elastic shock absorbing structure for vehicle is provided, and the present invention has the effect of sharing shock momentum and dual shock-absorbing.

For reaching aforesaid goal of the invention, it mainly comprises an air cusion body and an elastic component the present invention, wherein:

Form an air chamber in this air cusion body, this air chamber supplies ccontaining gas, and air cusion body central authorities offer the combined hole of a penetration state; And this elastic component is the structure of coiled type, and is the kenel that the diameter from coil to coil reduces by two ends toward the center, and elastic component is mounted on air cusion body inside; And be the circle winding and place the kenel of combined hole periphery, this combined hole supplies to establish with the shock absorbing apparatus group of automobile, and air cusion body is located respectively to be provided with two adapter plates up and down and inside and outside air cusion body, is relative clamping shape; Making air cusion body and shock absorbing apparatus steady device, and will on average be transmitted to air cusion body from the strength of shock absorbing apparatus by adapter plate and bear, and the adapter plate of air cusion body below is provided with several combined holes; This combined hole air feed pad is established with the firm lock of shock absorbing apparatus and is combined; When the air cusion body pressurized, this elastic component can bear the effect that external force produces shock-absorbing, and this air cusion body also can be shared the shock momentum that elastic component is loaded; Make external force partly disperse to bear, make the effect of the auxiliary pressure-bearing of air cusion body performance whereby to air cusion body by elastic component;

This shock absorbing apparatus is mounted on the automobile, and it comprises a combination end, a union link and a movable sleeve, and wherein this combination end and union link are established with automotive interior and set of wheels respectively; And this movable sleeve is to be arranged on the union link; Air cusion body of the present invention is to be installed on to combine between end and the movable sleeve, and makes union link be arranged in the combined hole of air cusion body, thereby when shock absorbing apparatus receives the vibrations pressure that wheel transmits; This movable sleeve is the pushing air cusion body; And through elastic component shock-proof effect by compression is provided, and when air cusion body stressed moment, the gas of air chamber can be brought into play the effect of pressurized buffering shock-absorbing; Make the vibrations pressure at initial stage can receive gas buffer in the air chamber earlier flexibly; And vibrations are after pressure increases gradually, and this elastic component promptly provides the effectiveness of damping by compression, make the present invention have sharing the effect of shock momentum and dual shock-absorbing whereby;

This air cusion body is provided with an air inlet valve and an air outlet valve; This air inlet valve and air outlet valve are the structure of Non-return air valve; It makes gas only can debouch air chamber with single direction, and a control system is to be mounted in the automobile, this control system be with wheel place shock absorbing apparatus on the air inlet valve and the air outlet valve of air cusion body be connected; Make the user get in the air chamber by air inlet valve with adjustment gas whereby through this control system; Or make gas flow out to the external world by air chamber through air outlet valve, and keeping the inner suitable gas flow of air chamber except that can suitably controlling, the shock-proof effect of also visual air cusion body and elastic component auxiliary block post generation each other adjusts; With the inner best gas flow of control discharge chamber, make the more perfect incabloc function of shock absorbing apparatus performance.
