Abstract

The utility model relates to a vibration decreasing device for a roadlouse. Two flabellate U-shaped rings are designed. The two ends of two absorbers which are across sleeved are respectively movably connected with the shaft pin structures of the arc-shaped ends and the circle center ends of the U-shaped rings. One end of the other two absorbers is respectively movably connected with the shaft pin structure of the cambered end of the U-shaped ring, and the other end of the other two absorbers is fixedly connected with a Y-shaped rocker. The fork end of the Y-shaped rocker is provided with a shaft pin structure.

Description

The miniature car shock attenuation unit

(1) technical field.The utility model relates to a kind of miniature car shock attenuation unit, is loaded on the small-sized people's of taking advantage of automobile, on car, baby car, minivan, cross-country car, commercial vehicle etc., reaches vibration damping.

(2) background technology.At present, be used for the small-sized people's of taking advantage of automobile, mainly contain the independent suspension device as the shock attenuation unit on car, minivan, the cross-country car etc., shock absorber (or spring) direct screening structure, leaf spring structure (steel plate adds shock absorber), steel plate structure etc., these apparatus features are: its damping means is support vehicle chassis or vehicle body directly, during vehicle ', shock attenuation unit can't absorb powerful impulsive force of external moment (energy) fully, cause the occupant to still have in various degree vibratory sensation and side pitch phenomenon, when particularly running at high speed, poor stability.

(3) summary of the invention.Technical problem to be solved in the utility model is a kind of people's of taking advantage of miniature car shock attenuation unit of design, to overcome vehicle side pitch phenomenon and roll force under steam, reduce occupant's vibratory sensation, increase comfort, reduce the damage of vehicle component, improve the safety of vehicle '.

The technical scheme that the utility model solves the problems of the technologies described above is: this shock attenuation unit design has two fan-shaped U type rings, be and intersect the two ends of two shock absorbers of suit and be movable dress connection with the pivot pin structure of the arc tips of U type ring and center of circle end respectively, other has two shock absorber one ends to be movable dress connection with the pivot pin structure of U type ring arc tips respectively, the other end joins with a Y type rocking arm dress respectively, and the fork design of Y type rocking arm has dress coupled axle-pin structure.The structure of four shock absorbers is identical, and design has piston barrel, and piston is housed in the piston barrel, on piston barrel and the piston rod spring is housed, and by helicitic texture bottom is housed on piston barrel one end, and hydraulic oil is housed in the piston barrel.Design has trip ring on the piston barrel outer wall, and design has the end cap equipped with piston rod on the other end, and design has the piston ring washer in the piston barrel.Design has dress connection hole on piston rod and the bottom connecting rod.

Effect of the present utility model.During use, with the fan-shaped center of circle end of two U type rings be and intersect two shock absorber bottom connecting rod ends of suit and be activity respectively by its pivot pin structure together and be loaded on the car chassis both sides, by the pivot pin structure Y type rocking arm fork is activity and is loaded on the car chassis both sides, the tail end of each Y type rocking arm gets final product with the wheel shaft dress connection of two rear wheels of automobile respectively.Generally be to be loaded on automobile back wheel axle and the corresponding chassis (vehicle body), also can be loaded on front-wheel and corresponding site simultaneously.So, form a soft suspension.When a certain sidecar wheel of automobile is subjected to external force to do the time spent, the shock absorber of adorning connection with the U type ring of this side mutually shrinks simultaneously, and the center of circle end swing offset of U type ring, external force does not directly act on the chassis, chassis or vehicle body be bob not substantially, because of two shock absorber two ends that intersect suits respectively be in the not U type ring dress connection of homonymy of chassis, bigger if certain side is subjected to external force, the shock absorber that the is positioned at car chassis one side adjustment that changes is to reduce vibrations.If automobile both sides wheel is subjected to external force simultaneously and does the time spent, the shock absorber of both sides is done above-mentioned adjustment simultaneously, reduces vibrations.When automobile turning, because the shock absorber two ends of two intersection suits are to adorn connection with the U type ring of both sides, chassis respectively, then adjust roll force, reduce vibrations.Therefore, because this device has the said structure design, form a dynamic soft balanced system, chassis or vehicle body just hang on this soft balanced system device, and external force does not directly act on car chassis or the vehicle body, thereby the side pitch phenomenon in the vehicle ', the roll force when turning have been overcome, reduce to travel and shake and noise, take advantage of a person to feel steady, comfortable, prolong each component life of vehicle, improve the safety of vehicle ', the safety of running at high speed improves more.

(5) specific embodiment

As shown in FIG., the utility model has two fan-shaped U type rings 1, be and intersect the two ends of two shock absorbers 3 of suit and be movable dress connection with the pivot pin structure 2 of the arc tips of U type ring 1 and center of circle end respectively, other has two shock absorber 3 one ends to be movable dress connection with the arc tips pivot pin structure 2 of U type ring 1 respectively, the other end is fixing dress connection with a Y type Rocker arm 4 respectively, and the fork design of Y type Rocker arm 4 has dress coupled axle-pin structure 2.The structure of four shock absorbers 3 is identical, and design has piston barrel 5, and piston 6 is housed in piston barrel 5, on piston barrel 5 and piston rod 7 damper spring 8 is housed, and logical state helicitic texture and on piston barrel 5 one ends bottom 9 is housed, and hydraulic oil 10 is housed in the piston barrel 5.Design has dress connection hole 11 on piston rod 7 and bottom 9 connecting rods.Designing on piston barrel 5 outer walls has trip ring 5C, and design has the end cap 5a equipped mutually with piston rod 7 on the other end, and design has the piston stopper 5b that is equipped with piston rod 7 in the piston barrel 5.During production, as required, on the connecting rod of a part of shock absorber 3, produce the slippage slot that has the intersection suit to use, as shown in Figure 4.When being installed on the automobile, mounting means as shown in Figure 6, to be and intersect the pivot pin of two shock absorbers 3 and the pivot pin structure 2 of the center of circle end dress connection of U type ring 1 of suit and take off, this end one of the center of circle end of U type ring, corresponding shock absorber 3 is reinstated pivot pin to be on the chassis 12 that activity is loaded on automobile, the fork of Y type Rocker arm 4 is activity by pivot pin to be loaded on the chassis 12, the axle weldering connection of its tail end and wheel 13 firmly promptly installs.During installation, generally this device is installed on automobile back wheel and the corresponding chassis 12, also can install at front-wheel simultaneously.During automotive operation, because this device plays soft suspension effect, the various external force that wheel 13 is subjected to are mutually adjusted through this device, and external force do not directly act on chassis 12 or the vehicle body, thereby thump is reduced, and comfortable when the people is taken, it is safer to travel.Shock absorber 3 can be made by oneself also can buy similar shock absorber from market.Pivot pin structure 2 is a prior art, is made up of pivot pin and nut, and its pivot pin can take off from relevant parts, is convenient to install with car chassis 12.
