Abstract
The utility model discloses a cylinder body type spring damper. The cylinder body spring damper comprises a cylinder body, an end cover, a piston and a piston rod. The piston is arranged in the cylinder body. The piston rod is connected with the piston by penetrating through the end cover. The lower end of the piston is provided with a spring. The bottom of the spring is provided with a magnet. One end of the spring is connected with the piston and the other end of the spring is connected with the bottom of the cylinder body. A spacing ring seat is fixed on the piston rod. A buffering block is arranged on the spacing ring seat. The upper end surface of the buffering block is in contact with the lower end surface of a guider. Compared with the conventional cylinder body type spring damper, the cylinder body type spring damper has following advantages: the risk that the spring is exposed outside is effectively decreased; an abrasion problem of a working cylinder is resolved in such a way that scrap iron is effectively absorbed; and service lifetime of the damper is prolonged.
Description
Technical field
The utility model relates to a kind of vehicular shock absorber that improves stability in the Vehicle Driving Cycle process, is specifically related to a kind of barrel-type spring damper.
Background technique
Vibration damper is the necessary equipment of motor vehicle, its working principle is, when relative movement appearred in vibrations between vehicle body and vehicle bridge, the piston in vibration damper moved up and down, and the damping oil in the vibration damper clutch release slave cylinder flows in another chamber through different holes from a chamber repeatedly.Friction between hole wall and damping oil and the intermolecular interior friction of fluid at this moment forms damping force to vibrations, and making the thump Conversion of Energy is damping oil heat energy, then absorbed and be dispersed in atmosphere by vibration damper.Friction process can produce iron filings, is mingled in damping oil the aggravation fretting wear.Foreign impacts or vibrations are when too large, and piston moves up and down distance and speed aggravation, and the load that easily causes vibration damper to bear is excessive and lost efficacy.application number is that 201020168845.9 Chinese utility model patent discloses a kind of Double-spring shock absorber, comprise piston rod, one end activity is plugged in piston rod, the stiffening rib that the other end is overhanging, be arranged on the lower union joint of piston-rod lower end and the connecting head of stiffening rib upper end, be enclosed within the cushion collar on stiffening rib, be enclosed within the gear cover of movable match middle-end, the gear button, be placed in kick spring and reinforcement spring between gear cover and upper binding head, gear cover lower end is provided with shift slot, the gear button swings selects gear, and then the gear cover moves up and down the active force that changes kick spring and reinforcement spring.This spring damper is because spring is exposed in external environment, easily wearing and tearing, in case the corrosion-resistant coating of spring outside be worn, corrosion that just can acceleration spring, thus shortened working life of vibration damper.
The model utility content
The purpose of this utility model is to provide a kind of barrel-type spring damper of new structure, and it can not only effectively reduce spring and be exposed to outer risk, and can effectively adsorb the problem that iron filings solve the clutch release slave cylinder wearing and tearing, thereby extends the working life of vibration damper.
For realizing this damping purpose, the technical solution of the utility model is: a kind of barrel-type spring damper, comprise cylindrical shell, end cap, piston and piston rod, described piston is located in cylindrical shell, described piston rod passes end cap and is connected with piston, described piston lower end is provided with a spring, described spring bottom is provided with magnet, described spring one end is connected with piston, the other end is connected with cylinder body bottom, on described piston rod, be fixed with spacing ring seat, spacing ring seat is provided with buffer stopper, and the upper-end surface of described buffer stopper contacts with the guider lower end surface.
As improvement of the present utility model, described piston rod is the inner hollow-core construction that is provided with vestibule.
As improvement of the present utility model, described piston rod surface is covered with a metal film layer.
As improvement of the present utility model, described end cap and piston rod joint are provided with the oil sealing of turnup structure.
The structural advantage of the utility model is: spring is arranged in cylindrical shell, and spring one end is connected with the piston lower end, and an end is connected with cylinder body bottom, and piston is connected with piston rod, reaches the effect of damping.Simultaneously, avoid spring to be placed in external environment, avoided spring to be worn and corrode, increased the working life of vibration damper.Oil sealing adopts turnup structure on the other hand, with guider and oil storage cylinder, be sealed and matched, the sealing of vehicle shock absorber is improved, this turnup structure has increased the bearing capacity of vibration damper sealing part simultaneously, improve the internal pressure of bearing of vehicle shock absorber, thereby improved the durability of product.
The accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation.
Wherein: 1 is piston rod, and 2 is end cap, and 3 is guide holder, and 4 is cylindrical shell, and 5 is piston, and 6 is spring, and 7 is suspension ring.
Embodiment
In conjunction with the embodiments the utility model is further illustrated with reference to the accompanying drawings.
As shown in Figure 1, a kind of barrel-type spring damper, comprise cylindrical shell, end cap, piston and piston rod, and described piston is located in cylindrical shell, described piston rod passes end cap and is connected with piston, described piston lower end is provided with a spring, and described spring bottom is provided with magnet, and described spring one end is connected with piston, the other end is connected with cylinder body bottom, on described piston rod, be fixed with spacing ring seat, spacing ring seat is provided with buffer stopper, and the upper-end surface of described buffer stopper contacts with the guider lower end surface.Wherein, described piston rod is the inner hollow-core construction that is provided with vestibule; Described piston rod surface is covered with a metal film layer; Described end cap and piston rod joint are provided with the oil sealing of turnup structure.
Though it is pointed out that above-described embodiment is to the utility model detailed text description of contrasting, these text descriptions are just to the simple description of the utility model mentality of designing, rather than to the restriction of the utility model thinking.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
