Abstract
The utility model discloses a press from both sides along formula air spring belongs to the automobile shock absorber device, aim at providing an apron and the rubber utricule is connected reliably, the seal is good, the bearing capacity is big air spring. It include upper and lower two ends opening the rubber utricule, with this rubber utricule on port fixed connection the apron, fix on this apron and the suction nozzle of rubber utricule intercommunication and a plurality of connecting bolt, with the rubber utricule under the port link firmly and with its sealed piston, the apron comprises outer splint (4) that are the shape of falling character cut in bas -relief structure, inner splint (2) that are the loudspeaker form, and it is outwardly directed that splint (4) are welded on this inner splint and outside passing in connecting bolt (3) and suction nozzle (1), piston (6) are hollow structure, and the top of this piston distributes and has gas pocket (7) that communicate with rubber utricule (5). The utility model has the advantages of the shock attenuation is soft, bearing capacity is strong, long service life, with low costs, it a vehicle air spring.
Description
Technical field
The utility model relates to a kind of pneumatic spring, particularly relates to a kind of folder edge formula 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, but the mode adopting crimping to fasten between cover plate with rubber utricule upper end-hole is connected, assembling difficulty is not only caused because rubber utricule upper end-hole is harder, and the join strength of cover plate and rubber utricule is lower, easily leak because of pressure increase between cover plate and rubber utricule, even come off, reliability is poor.In addition, the piston due to conventional construction pneumatic spring is solid construction, and piston cavity can not be communicated with rubber utricule, and easily burst or come off during rubber utricule pressurized, bearing capacity is less.3rd, the cover plate crimping place of conventional air bellows is easily out of shape because of stressed for a long time, causes cover plate to be scrapped, can not reuse.
Summary of the invention
For the above-mentioned defect existed in prior art, the utility model aims to provide the folder edge formula pneumatic spring that a kind of cover plate is connected reliably with rubber utricule, good leak tightness, bearing capacity are large.
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 cover plate be fixedly connected with this rubber utricule upper end-hole, be fixed on this cover plate is communicated with described rubber utricule air inlet nozzle and multiple connecting bolt, be connected and the piston sealed with rubber utricule lower end mouth; Described cover plate is by the external splint in undercut shape structure, form in trumpet-shaped inner splint, and connecting bolt and air inlet nozzle to be welded on this inner splint and protruding through external splint; Piston is hollow-core construction, and the top portion of this piston is furnished with the pore be communicated with rubber utricule.
Piston is connected by the upper end-hole of the limiting buffer block and rubber utricule that are fixed on its top and is sealed.
Compared with the prior art, the utility model is owing to have employed technique scheme, change original fixed cover plate into be made up of external splint and inner splint fabricated structure, therefore by external splint, inner splint, the upper end-hole of rubber utricule has been clamped by connecting bolt; Not only regulate clamping dynamics, convenient for assembly or maintain and replace by connecting bolt, and external splint and inner splint not yielding, reusable.In addition, owing to original solid construction piston have been changed into the hollow-core construction be communicated with rubber utricule, therefore can store the pressurized air in rubber utricule during pressurized, not only can alleviate the pressure of rubber utricule, extend its working life, but also damping mildness can be improved.3rd, because the top at piston adds limiting buffer block, piston direct striking cover plate when therefore can overcome pressurized and cause its distortion and the fierce defect of vibrations.The utility model has good leak tightness, connection between cover plate and rubber utricule is simple and reliable, shock-absorbing performance is good, bearing capacity is strong, long service life, low cost and other advantages.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that after the utility model removes piston, rubber utricule is in free state.
In figure: air inlet nozzle 1, inner splint 2, connecting bolt 3, external splint 4, rubber utricule 5, piston 6, pore 7, limiting buffer block 8.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
As shown in Fig. 1 ~ 2: the upper end-hole of rubber utricule 5 and lower end mouth are uncovered structure, the upper end-hole of this rubber utricule is airtight by the cover plate be connected with it, this cover plate has the air inlet nozzle 1 be communicated with rubber utricule 5; The lower end mouth of rubber utricule 5 is airtight by the piston 6 be connected with it.Described cover plate by be arranged in rubber utricule 5 upper end-hole be trumpet-shaped inner splint 2, in concave shape structure and the external splint 4 tipping upside down on rubber utricule 5 upper end-hole outer rim form.Multiple connecting bolt 3 is welded on inner splint 2 also protruding through external splint 4, and air inlet nozzle 1 is welded on inner splint 2 also protruding through external splint 4.Piston 6 is hollow-core construction, and its top portion is furnished with the pore 7 be communicated with rubber utricule 5.
In order to avoid piston impact cover plate, piston 6 is connected by the limiting buffer block 8 being fixed on its top with rubber utricule 5 upper end-hole and is sealed.
When connecting bolt 3 is connected with car body, the upper end-hole of rubber utricule 5 can clamp by inner splint 2 and external splint 4.
Claims (2)
1. the cover plate press from both sides an edge formula pneumatic spring, comprise the rubber utricule of upper and lower open at both ends, being fixedly connected with this rubber utricule upper end-hole, be fixed on air inlet nozzle that this cover plate is communicated with described rubber utricule and multiple connecting bolt, and rubber utricule lower end mouth be connected and the piston sealed; It is characterized in that: described cover plate is by the external splint (4) in undercut shape structure, forms in trumpet-shaped inner splint (2), and connecting bolt (3) and air inlet nozzle (1) to be welded on this inner splint that also to pass external splint (4) protruding; Piston (6) is hollow-core construction, and the top portion of this piston is furnished with the pore (7) be communicated with rubber utricule (5).
2. folder edge formula pneumatic spring according to claim 1, is characterized in that: piston (6) is connected by the upper end-hole of the limiting buffer block (8) Yu rubber utricule (5) that are fixed on its top and is sealed.
