Description
Technical field
The utility model relates to auto parts and components, especially a kind of adjustable elastic Vibration absorber of car device.
Background technique
Along with the development of society, the requirement of people to automobile is also more and more higher, includes the requirement of the performances such as the power character of automobile, Economy, braking, control stability, smoothness, passing ability.Vibration damper is mounted in a damping member between car body and road wheel, its effect is the vibration of decay car body and stops the unlimited increase of resonant conditions lower body amplitude, amplitude and the vibration number of body oscillating can be reduced, the travelling comfort that the fatigue life that thus can extend elastic element rides with raising people.For accelerating the decay of body vibrations, improving vehicle running smoothness, in the suspension of most of car, all vibration damper being housed.Vibration damper and elastic element are installed in parallel.Wherein adopting is dydraulic shock absorber the most widely, also known as Hydraulic shock absorber, existing referred to as telescopic shock absorber.Different according to structural type, vibration damper is divided into rocking arm type and cartridge type two kinds.And telescopic shock absorber working pressure is only at 2.5-5Mpa, but its stable work in work and being widely used on the automobile in modern times.Telescopic shock absorber can be divided into single-cylinder type, double barreled again.The damping force of vibration damper is larger, and vibration is eliminated faster, but the effect of elastic element in parallel can not be given full play to; Link and vehicle frame also may be caused to damage.Generally for and ensure that the damping force produced in recuperation is more much bigger than the damping force produced in compression stroke, thus rebuilt valve spring rate and pretightening force larger than compression valve; Under same oil pressure effect, people having a common goal's sectional area summation in rebuilt valve and corresponding gap is usually less than the usual sectional area summation in compression valve and corresponding gap usually.Also ensure that like this and be suspended in compression stroke, the damping force of vibration damper is less, so that the elasticity making full use of elastic element is to relax impact; In recovery stroke, the damping force of vibration damper should be comparatively large, in the hope of rapid vibration damping.Because the pavement behavior of automobile running is different, vibration damper used requires also can be different.Because of the difference of external condition, also can be different accordingly to the usage requirement of vibration damper.In different countries or different areas, weather environment, road etc. have very large difference.Single vibration damper is the performance requirement that impossible all meet them.Along with the development of society, there is sectionalization in automobile market, car manufactures start to produce the automobile of to one's name characteristic: the triumphant moral clarke SLS of AM General automobile making, the Audi TT of germany volkswagen automobile making have adopted the adjustable suspension of electromagnetism, Germany's benz, Porsches adopt air suspension, and french citroen C5 overseas edition adopts the adjustable suspension of hydraulic pressure.Faster than traditional suspension 5 times of the reaction velocity of these are adjustable suspension, even on the road surface of jolting most, also can ensure vehicle smooth-ride.Up to the present, the automobile of domestic production is due to the restriction such as technology, the cost seldom adjustable suspension of use, and most of automobile uses common pellet type vibration damper.
The problem that common pellet type vibration damper exists is: spring holder and fuel tank are for fixedly to weld, along with the prolongation of operating time, damper elastomeric element is aging gradually, reduced stiffness, its damping property is constantly degenerated, thus have influence on stationarity and the travelling comfort of automobile running, usually need then to change.For general car, particularly go-anywhere vehicle, if when traveling road condition change is larger, just different to the requirement of the damping property on chassis, as the automobile that travels on municipal highway because road conditions are good, suspension system reduce about 20% power better to the smoothness of automobile and comfortable feel, and country road road conditions are poor, suspension system need the power of increase about 30% to the smoothness of automobile running and Security better.This just requires that suspension system elastic force is adjustable, and some middle and high end cars all use adjustable suspension for this reason, as adjustable air suspension, oleo-pneumatic suspension, adjustable electromagnetic suspension etc., but adjustable suspension frame structure is complicated, cost is high, and rate of fault is high, in low car can not accept.
Summary of the invention
The purpose of this utility model will solve common pellet type damper elastomeric element exactly, and easily aging needs is changed, and working life is short, can not adapt to the traveling of different road conditions, affect the problems such as travelling comfort, provides a kind of adjustable elastic Vibration absorber of car device.
Concrete scheme of the present utility model is: improve for common pellet type vibration damper, it has fuel tank, the in-built clutch release slave cylinder of fuel tank and piston rod, oil sealing and guider are equipped with in the front end of clutch release slave cylinder, tail end is equipped with compression valve sub-assembly and fuel tank tailstock, the tail end of piston rod is equipped with piston sub-assembly, spring holder is equipped with in the outer wall stage casing of fuel tank, back segment is equipped with connection bracket, it is characterized in that: the installation place being positioned at spring holder at fuel tank outer wall, be shaped with one section of outside thread, be fitted with nut seat and locking nut, described spring holder is fixed on nut seat.
The thread section length of the outer wall of fuel tank described in the utility model is 60-80mm.
Be provided with stop collar and buffer stopper on the piston rod in the utility model, buffer stopper is arranged near stop collar.
Between spring holder and fuel tank, adding nut seat and locking nut in the utility model, make the mounting point of spring holder adjustable, realize the adjustable of vibration damper, utilizing the spring-compressed hardness and the flexibility that change suspension system different from drawing high position.The present invention is after damper elastomeric component ageing, reduced stiffness, position height by Regulation spring dish realizes elastic element and recovers rigidity, improve working life, simultaneously by the position height of Regulation spring dish, meet the traveling of car in different road conditions, keep stationarity and the travelling comfort of automobile.
