Abstract
The utility model relates to a shock absorber, which comprises a shock absorbing cylinder and a guide rod, wherein the guide rod is fittingly connected with the shock absorbing cylinder via a first snap spring, the first snap spring is arranged approaching the upper end of the shock absorbing cylinder, an upper guide sleeve and a lower guide sleeve which are engaged with the inner diameter of the shock absorbing cylinder are respectively sleeved below the first snap spring on the guide rod and the lower end of the guide rod, an elastic buffer device consisting of a main spring and a lower elastic buffer block disposed in the main spring is arranged between the bottom end surface of the guide rod and the inner bottom surface of the shock absorbing cylinder, and a return buffer device is arranged between the upper guide sleeve and the lower guide sleeve of the guide rod. According to tests, the buffer system consisting of the buffer block, the spring and the return buffer device has buffer effect equal to the hydraulic buffer effect of a motorcycle, but the cost of the buffer system is much lower than that of a hydraulic system.
Description
Technical field
The utility model belongs to Motor Vehicle front fork technical field, relates to a kind of vibration damper.
Background technique
When vehicle driving on rugged road or when sailing hollow into because of carelessness, rely on damping device between wheel shaft and the handlebar to reduce the impact that handlebar and car load are subjected to, existing motorcycle generally reaches this effect by at front fork the hydraulic cushion shock absorber system being installed, but cost is higher; Existing storage battery car then only reduces the impact that handlebar is subjected to by single spring damper is installed at front fork, but this effect is poor, and when running into hollow, cyclist's vibrations are bigger, and injured easily.
Summary of the invention
The purpose of this utility model provides a kind of vibration damper of simple in structure, with low cost, good buffer effect.
The technological scheme that the utility model adopted is to achieve the above object of the invention:
A kind of vibration damper, it is characterized in that: it comprises damper cylinder and the guide rod that is connected by first jump ring with it, first jump ring is positioned at the upper end near damper cylinder, first jump ring below and lower end of the guide rod on the guide rod are socketed with the upper and lower guide sleeve that cooperates with the damper cylinder internal diameter respectively, are provided with elastic buffering mechanism between guide rod bottom end and the damper cylinder inner bottom surface.
Described elastic buffering mechanism is by main spring and be positioned under the elasticity of main spring buffer stopper and form.
Described buffer stopper down is the block rubber of upper end open, boring.
Be provided with the return damping device between the upper and lower guide sleeve of described guide rod.
Described return damping device comprises second jump ring that is connected on the guide rod, is provided with damping spring between second jump ring and the last guide sleeve.
Described guide sleeve down is an open tank shape structure, and end in contact on its bottom surface and the main spring is provided with compression spring between main spring lower end and the damper cylinder inner bottom surface, be provided with pad between the damping spring lower end and second jump ring.
Interlocking has smooth, wear-resisting guide bush on the described guide sleeve down, and wherein descending between guide sleeve and the damper cylinder is Spielpassung, and guide bush contacts with the damper cylinder inwall.
Described going up between guide sleeve and first jump ring is with seal ring, seal ring big or small with guide rod, damper cylinder between gap length cooperate, the damper cylinder top is equipped with the dust-proof cover that cooperates with guide rod.
The utility model is provided with buffer stopper down in main spring, when main spring is compressed into down guide sleeve and contacts with following buffer stopper, following buffer stopper inner chamber is sealed, this at present buffer stopper serve as pressure system and strengthen buffer function, in the reseting procedure of main spring, on, return damping device between the following guide sleeve plays buffer function to the guide rod that upwards slides fast, significantly reduced Motor Vehicle jerk in the process of moving, ensure cyclist's personal safety, through evidence: buffer stopper, spring and return damping device are suitable substantially in conjunction with the hydraulic cushion effect of buffer system cushioning effect that constitutes and motorcycle, but with low cost; Wherein the effect of smooth abrasion-proof guide bush is the following guide sleeve of protection and reduces the coefficient of sliding friction.
