Abstract
The present invention relates to a hydraulic vibration damper of a corrugated pipe, particularly to a vibration damper capable of replacing a piston type hydraulic vibration damper, which is composed of two segments of corrugated pipes, an inner pipe, an outer pipe, a horizontal partition plate, etc. The relative movement of the inner pipe and the outer pipe drives horizontal partition plate to move and make the corrugated pipes telescopic. The volume of the corrugated pipe on one side of the horizontal partition plate is increased, and the volume of the corrugated tube on the other side is decreased to force oil in the corrugated pipes to flow through throttling orifices on the horizontal partition plate and generate resistance so as to replace the motion of the piston of the piston type hydraulic vibration damper in an oil cylinder. Liquid which flows through the throttling orifices on the piston generates the resistance. The present invention avoids the failure of oil leakage caused by the abrasion of the piston and the wall of the oil cylinder. Therefore, the present invention has the advantages of long service life, no need of finish machining and low cost.
Description
The present invention is a kind of vibration damper, is a kind of hydraulic machinery that reduces mechanical vibration such as vehicle, machine.
Used dydraulic shock absorbers such as passenger train, car, motor cycle rear wheel are piston type hydraulic damper entirely now.Ubiquity leakage of oil problem is not improved from structure at all, is difficult to overcome.According to first phase and the railroad engineer first phase in 1998 in March, 1997 in railway epoch report, what French General Electric Alstom and Dutch KONI company promoted to China also is piston type hydraulic damper.
The objective of the invention is to improve the performance of dydraulic shock absorber, reduce cost.
The claimed technological scheme of the present invention is the piston type hydraulic damper that is made of oil cylinder, piston, piston rod, oil storage cylinder and coupling with the dydraulic shock absorber replacement that two sections bellowss, diaphragm, upper and lower end plate, inner and outer pipes and coupling constitute.
The present invention and piston type hydraulic damper comparison one are durable, and the piston of piston type hydraulic damper, cylinder wall, piston rod will wear away, and damping property constantly weakens, and will lose efficacy to certain degree.Key component of the present invention does not contact friction, and bellows is pressed the fatigue strength design, can not lose efficacy.The 2nd, cost is low.The oil cylinder of piston type hydraulic damper, piston, piston rod all must be used high-abrasive material fine finishing.Key component bellows of the present invention is a kind of approved product of roll forming, does not need fine finishing.The piston type hydraulic damper piston has the partial volume of piston rod and piston-rodless to change different when moving in oil cylinder, oil in the oil cylinder of piston-rodless flows to, flows out in the oil storage cylinder by fuel tap, when diaphragm of the present invention moves, both sides bellows volume-variation is identical, needn't establish oil storage cylinder, cost is further reduced.
Accompanying drawing is the sectional view of hydraulic vibration damper of corrugated pipe of the present invention.

Realize that best way of the present invention is that two sections identical upward bellowss (1) and following bellows (2) are welded on the both ends of the surface of circular diaphragm (3), as shown in drawings.Have on the diaphragm with the piston type hydraulic damper piston on identical throttle orifice (4), produce resistance when oil flows through.Last bellows upper end is welded on upper head plate (5) lower end surface, and upper head plate has an oil hole (6), injects an amount of oil back screw (7) sealing to bellows.Following bellows lower end is welded on lower end sheet (8) upper-end surface.The end plate periphery is welded on the inwall of interior pipe (9) two ends up and down.Interior pipe middle part uniform four axial channel (10) are so that connect with outer tube (11) diaphragm with coupling block (12), screw (13).The range that the length of guide groove equals to design.In the other end of interior pipe outer tube burn-on attachment pegs (14), (15), so that be installed on the object of the relative movement that needs vibration damping.Interior pipe is fixed upper head plate and lower end sheet, and outer tube drives the diaphragm motion, makes bellows flexible, on one side volume becomes greatly, Yi Bian diminish, forces oil to flow through throttle orifice on the diaphragm, generation resistance.
Claims (2)
1, hydraulic vibration damper of corrugated pipe, particularly a kind of and existing piston type hydraulic damper is the same to utilize the hydraulic machinery of the resistance that flow of liquid produces when throttling pore,
Its technological scheme is that two sections identical last bellowss (1) and following bellows (2) are welded on the both ends of the surface of circular diaphragm (3), have on the diaphragm with the piston type hydraulic damper piston on identical throttle orifice (4), last bellows upper end is welded on upper head plate (5) lower end surface, upper head plate has an oil hole (6) and sealing screw (7), following bellows lower end is welded on lower end sheet (8) upper-end surface, the end plate periphery is welded on the inwall of interior pipe (9) two ends up and down, interior pipe middle part uniform four axial channel (10) are so that with diaphragm and outer tube (11) coupling block (12), screw (13) connects; The range that the length of guide groove equals to design; In the other end of inner and outer pipe burn-on coupling pin (14), (15), so that be installed on the object that needs vibration damping; When the inner and outer pipes relative movement, on one side diaphragm forces the bellows volume to become greatly, Yi Bian diminish, flow of liquid is crossed the throttle orifice on the diaphragm, produces resistance; It is characterized in that: upper and lower bellows, interior pipe, the upper and lower end board component has replaced the oil cylinder of piston type hydraulic damper; Diaphragm has replaced the piston of piston type hydraulic damper; Outer tube has replaced the piston rod of piston type hydraulic damper; The Sealing, oil storage cylinder and the annex thereof that do not have piston type hydraulic damper.
2, according to the described vibration damper of claim, its spy can connect adjustable valve on the end plate up and down, replaces throttle orifice.
