Abstract
The utility model discloses a toper utricule air spring belongs to the automobile shock absorber device, aim at providing a long service life, shock attenuation effectual, take air spring comfortable, that the sealing reliability is good. It include upper and lower two ends opening the rubber utricule, with this rubber utricule under port fixed connection the sealing member, fix on this sealing member with the suction nozzle of rubber utricule intercommunication, with the rubber utricule on the port link firmly and with its sealed piston, the port had the bell structure of turn -up under rubber utricule (3) were, sealing drum (4) of sealing member for being connected through port lock under turn -up and this rubber utricule, this sealing drum has complex guide cylinder (6) with it outward, it has exhaust hole (7) to distribute on this guide cylinder, and piston (1) links firmly with guide cylinder (6). The utility model has the advantages of the seal is good, the shock attenuation is soft, take comfortable, long service life, it a vehicle air spring.
Description
Technical field
The utility model relates to a kind of pneumatic spring, particularly relates to a kind of taper utricule pneumatic spring; Belong to automobile shock-absorber.
Background technique
Pneumatic spring fills with pressurized air in telescopic seal container, utilizes a kind of damping device of aeroelastic effect.Its working principle is filled with pressurized air in leather bag inside, and the reaction force utilizing pressurized air to be formed is to support vehicle body and damping.Compared with other spring, pneumatic spring has that nonlinear characteristics, rigidity and bearing capacity can regulate, rigidity changes with the change of load, work the advantage such as soft, is thus widely used.At present, pneumatic spring usually by the cover plate be fixedly connected with this rubber utricule upper end-hole, be fixed on air inlet nozzle that this cover plate is communicated with rubber utricule and multiple connecting bolt, the piston that is fixedly connected with rubber utricule lower end mouth forms (if Authorization Notice No. is the pneumatic spring of CN203656003U); Although fairly simple, when rubber utricule frequent pressurized cyst wall easily tired because of frequent expansion, working life is shorter; In addition, the rubber utricule of conventional construction is generally cylindrical tube shape structure, and pressurized and varus and reset amount of deformation are comparatively large, and cyst wall is easily tired and lost efficacy.3rd, owing to there is no guiding device, rubber utricule easily because of unbalance stress deflection, can not vertical up-or-down movement be kept; Not only affect riding comfort, and rubber utricule also easily damages or threads off.
Summary of the invention
For the above-mentioned defect existed in prior art, the utility model aims to provide a kind of long service life, good damping effect, ride comfort, taper utricule pneumatic spring that sealing reliability is good.
To achieve these goals, the utility model is by the following technical solutions: it comprise the rubber utricule of upper and lower open at both ends, the Sealing be fixedly connected with this rubber utricule lower end mouth, be fixed on the seal is communicated with described rubber utricule air inlet nozzle, be connected and the piston sealed with rubber utricule upper end-hole; Rubber utricule is the campanula halleri Halleri of lower end mouth with crimping, and described Sealing is the sealing drum be fastened and connected by crimping and this rubber utricule lower end mouth, has the guide cylinder coordinated with it outside sealing cylinder; This guide cylinder is distributed with exhaust port, and piston and guide cylinder are connected.
Piston is by being fixed on limiting buffer block bottom it and rubber utricule upper end-hole is connected and is sealed.
Compared with the prior art, the utility model, owing to have employed technique scheme, has changed original sealed cover into sealing drum, can hold the air in utricule when rubber utricule pressurized; Therefore not only can avoid the defect of rubber utricule frequent expansion and fatigue, increase the service life, and can also increase damping mildness, improve riding comfort.In addition, owing to having changed cylindrical tube shape structure original for rubber utricule into campanula halleri Halleri, therefore utricule distortion and reset is more prone to, alleviate cyst wall further holds fatigable defect.3rd, guide cylinder is set outside sealing drum and can avoids rubber utricule, because of unbalance stress, deflection occurs, not only can further improve travelling comfort, but also the defect that rubber utricule can be avoided easily to thread off taken.The utility model has that good leak tightness, damping are soft, the advantage such as ride comfort, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is in free state;
Fig. 2 is the structural representation that the utility model is in compressive state.
In figure: piston 1, limiting buffer block 2, rubber utricule 3, sealing drum 4, air inlet nozzle 5, guide cylinder 6, exhaust port 7.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
As shown in Fig. 1 ~ 2: rubber utricule 3 is upper end-hole and lower end mouth is uncovered campanula halleri Halleri, the wired outer crimping (not indicating in figure) that turns up of the lower end mouth band of this rubber utricule; In sealing drum 4 is inwardly ploughed under by nozzle, crimping (not indicating in figure) is fastened and connected with the lower end mouth of rubber utricule 3, and the bottom welding of sealing cylinder has the air inlet nozzle 5 with rubber utricule 3 inner space.The upper end-hole of rubber utricule 3 is sealed by the piston 1 be fixedly connected with it, has the guide cylinder 6 coordinated with it, this guide cylinder is distributed with exhaust port 7 outside sealing drum 4, and piston 1 and guide cylinder 6 are connected.
At the bottom of the cylinder of piston impact sealing drum 4, piston 1 is connected by the limiting buffer block 2 be fixed on bottom it with rubber utricule 3 upper end-hole and is sealed.
Claims (2)
1. a taper utricule pneumatic spring, the Sealing comprise the rubber utricule of upper and lower open at both ends, being fixedly connected with this rubber utricule lower end mouth, be fixed on the seal is communicated with described rubber utricule air inlet nozzle, be connected and the piston sealed with rubber utricule upper end-hole; It is characterized in that: rubber utricule (3) is for lower end mouth is with the campanula halleri Halleri of crimping, and described Sealing is the sealing drum (4) be fastened and connected by crimping and this rubber utricule lower end mouth, has the guide cylinder (6) coordinated with it outside sealing cylinder; This guide cylinder is distributed with exhaust port (7), piston (1) and guide cylinder (6) are connected.
2. taper utricule pneumatic spring according to claim 1, is characterized in that: piston (1) is connected by the limiting buffer block (2) be fixed on bottom it with rubber utricule (3) upper end-hole and is sealed.
