Description
Technical field
The present invention relates to automobile suspension system, be specifically related to the preceding vibration damper of McPherson strut system.
Background technique
Along with the day by day increase of people to vehicle ride comfort's requirement, the automobile chassis suspension coupling more and more becomes the emphasis of each big automobile enterprises pay attention, wherein bracket of shock absorber is as performance parts important in the suspension system, it not only has influence on the riding comfort of vehicle, but also affects the control stability and the steering behaviour of car load.So the debugging of vibration damper is become naturally the key of chassis suspension coupling.
McPherson strut structure classics, but because its arrangement space is limited, so the debugging of its vibration damper is also limited to some extent.At present to the debugging of vibration damper before this type of suspension to use traditional common vibration damper, this vibration damper can not be dismantled for the welded seal assembly, can not adjust spring tray height and angle.Can only rely on a large amount of different damping parameter of making and the vibration damper of spring tray to mate.But for performance optimization, this is nowhere near.At present because be limited by the height of automobile enterprise coupling level and the degree of enriching of coupling engineer experience, the mode that also has a large amount of automobile enterprises employing multi-scheme when debugging to make the exemplar of a large amount of different damping is mated, so not only need to expend a large amount of human and material resources, financial resources, more need long fabrication cycle, especially often can not obtain optimum matching result.
Summary of the invention
The purpose of this invention is to provide a kind of adjustable bracket of shock absorber, be mainly used in the McPherson strut coupling.The production quantity of vibration damper exemplar was saved a large amount of human and material resources and financial resources when at first it can reduce to mate greatly; Secondly it can be adjusted the spring tray angle according to coupling engineer's requirement; The 3rd it can adjust the spring tray height; The 4th it be a kind of dismountable vibration damper, can easily vibration damper be opened, change the inner valve architecture; The 5th its various adjustment (spring tray angle, spring tray height, damping force) are convenient and simple, can greatly shorten match time.
A kind of adjustable bracket of shock absorber of the present invention includes vibration damper, spring tray, connecting rod support and knuckle support, and described connecting rod support and knuckle support are welded on the oil storage cylinder bottom of vibration damper; It is characterized in that: one section outside thread is arranged at described oil storage cylinder middle part; Design has snap close dish, snap close dish to comprise laterally zygomorphic two in addition, all screw on the outside thread that is connected the oil storage cylinder middle part with thread connecting mode, and two snap close valve snail line rotation directions is opposite up and down, mutually locking; Described spring tray is enclosed within on the oil storage cylinder, is movable part, and its lower surface is supported on the snap close dish, and upper surface is used for cooperating with spring, and the snap close dish is folded latch bracket and supported and spacing effect.
Described vibration damper comprises piston rod, oil storage cylinder, is installed in the clutch release slave cylinder in the oil storage cylinder and is installed in the interior inner valve of clutch release slave cylinder is assembly.Further, be detachable end with the end cover designs of the upper end of oil storage cylinder, described end cap is connected threadably with oil storage cylinder, and seals with seal ring at connection part.When needing to adjust damping force, can end cap be opened in the other direction along screw thread, and then adjust inner valve system with adjustable spanner.
Described oil storage cylinder is provided with gas charging valve, is used to charge into vibration damper nitrogen, to obtain better damping oil anti-bubble performance and to eliminate abnormal sound.
Spring tray of the present invention is movable, just can make the spring tray at different inclination angles, only needs when needing to change the spring holder angle that pallet is taken off replacing and gets final product.Also can pass through the rotary tray direction, change the lateral force direction.
Two snap close dishes with forward and reverse internal thread of the present invention can move up and down on oil storage cylinder, and locked mutually by positive left-hand thread, thereby reach the purpose that changes the spring tray height.
The present invention compares with prior art and has the following advantages:
The first, can adjust damping force, spring tray angle, spring tray height simultaneously, easy to adjust and simple, and can conveniently inflate, improved matching efficiency; Shortened the chassis suspension fork of vehicle debugging cycle greatly;
The second, the vibration damper exemplar quantity that has needed when having significantly reduced coupling was reduced to 2 to 4 by 60 ~ 80 former exemplars;
The 3rd, vibration damper is detachable structure, and convenient valve system to inside adjusts, and is to obtain desirable absorber damping force, reusable.
