Abstract
The utility model provides a vibration-damper which is used as a support and suspension device for vehicles or shockproof machines. The utility model is mainly composed of a damping cylinder with a hole, a piston without an opening hole, etc. When the utility model gets impact force suddenly, the piston without an opening hole moves up and down, and liquid or gas is forced to flow out or suck in by the damping cylinder with a hole. Resistance force for damping impact force and supporting spring rebound force is generated, the size of the resistance force is in direct proportion with a travel speed, and no high voltage is generated to a sealing element by liquid. Thus, the liquid is not leached, and the damping effect is stable. The damping cylinder with a hole is connected with the upper and the lower ends of a storage cylinder by a wire opening, thus, installation kits are convenient for assembly, disassembly and change, and the service life is long.
Description
The utility model relates to vehicles such as motor bike, automobile, bicycle and shockproof mechanically support, the manufacturing and the maintenance of suspension gear.
Its absorbing liquid of bumper extensively sold or gas are made high-pressure flow up and down in damping cylinder in the market, therefore absorbing liquid or gas just produce powerful pressure to various sealing members, liquid or gas just easily leach, overflow, thereby reduce damping effect, pollute exterior part, influence outward appearance.Two ends up and down because of its shell and damping cylinder all interfix through welding, riveted joint again, and are impaired as its interior fittings, and liquid feeding or gas etc. all is difficult to change, maintenance, has only integral replacing, so just causes very big waste.
The purpose of this utility model is to provide a kind of bumper, and its damping cylinder two ends up and down is porose respectively, and all less than the aperture and the quantity of upper end hole, liquid or gas in its damping letter communicate with storage cylinder for the aperture of following stomidium, quantity.Piston in the porose damping cylinder does not have open hole, and the two ends up and down of porose damping cylinder and storage cylinder all are to link fixing bumper mutually with the accessory that the silk mouth is arranged.
A kind of bumper of the present utility model is achieved in that it mainly comprises: porose damping cylinder, no open hole piston, have the lid in knurled nut, compositions such as internal thread convex lower adaptor.Play the bumper of bumper and absorbing shock effect with liquid or gaseous matter.
Its advantage of a kind of bumper of the present utility model is: the absorbing liquid in porose damping cylinder and the storage cylinder is in same level attitude with no open hole piston.When bumper is subjected to influencing of impulsive force suddenly, no open hole piston moves down, the porose damping cylinder volume of its underpart diminishes, hydraulic pressure or air pressure rising, liquid or gas are forced to flow into storage cylinder from the aperture of lower end, liquid or gas must be subjected to certain resistance during by above-mentioned duct, thereby play the damping, buffering effect, therefore can avoid impact excessive in the compression process support spring.As the amount that flows into storage cylinder is big, and liquid or gas can flow into its upper end and be equipped with storage through the macropore of porose damping cylinder upper end; When impulsive force disappears, under the effect of support spring, no open hole piston moves up, the upper volume of porose damping cylinder diminishes, liquid flows into storage cylinder again, and lower volume becomes and greatly just to produce negative pressure, from and through aperture inspiration liquid or gas in the storage cylinder, same aperture produces resistance to liquid or gas, therefore weaken the bounce of support spring again to bumper, from and play the damping, buffering effect, further make shock attenuation.Drag energy increases with the increase of no open hole piston traveling speed.And can not produce high pressure to various sealing members when liquid or gas flow and do not contact, so liquid that can not leaches, gas can not overflowed, thereby is difficult for reducing damping effect, be difficult for polluting exterior part and outward appearance.All be to tighten fixing mutually because of the two ends up and down of the porose damping cylinder of this kind bumper and storage cylinder again by parts that have silk mouthful, therefore more help maintenances such as the replacing of its inner each spare and accessory parts, liquid feeding, increase service life, and mounting equipment is simple, the fast cost of assembling reduces greatly.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
The utility model structural representation:
A kind of bumper of the present utility model comprise by put in the internal thread convex lower adaptor 1 flexible gasket 2 lower end with porose damping cylinder 3 patch into, tighten with the lower end of storage cylinder 4 is external again, inject an amount of absorbing liquid 5 from porose damping cylinder 3 and storage cylinder 4 then, spring height adjustment supporting disk 6 is inserted in the location from storage cylinder 4; Knurled nut 8 in the lid, rubber seal 9, location metal seal 10, crashproof movable spring 11, no open hole piston 12 and pad 13 have been inserted in again successively from piston rod 7 bottoms, with nut 14 pad 13 and no open hole piston 12 and piston rod 7 are inserted in the porose damping cylinder 3 and in the storage cylinder 4 after fixing successively, interior and tighten fixing with there being the interior knurled nut 8 of lid that rubber seal 9 is pressed into storage cylinder 4 then.From piston rod 7, be inserted in crashproof rubber pad 15, nut 17, support spring 16 successively again.The support spring 16 bottoms spring height adjustment supporting disk 6 of packing into is screwed into top connection 18 piston rod 7 upper ends again and the upper end of support spring 16 is fixed, and is again that nut 17 is fastening with top connection 18 and piston rod 7, finishes assembling.
Claims (1)
1, a kind of bumper, comprise the bumper that plays the damping, buffering effect with hydraulic pressure, air pressure, it is characterized in that: the two ends up and down of porose, the no open hole piston in damping cylinder two ends, porose damping cylinder and storage cylinder are respectively with the nut that covers convex being arranged and having the lower adaptor of internal thread convex to link fixing.
