Abstract
A hydraulic vibration damper with corrugated pipe used to replace piston-type hydraulic vibration damper is composed of two corrugated pipes, internal and external tubes and transverse partition. The relative movement of internal and external tubes drives the transverse partition to move, resulting in that one corrugated pipe is shortened and another extended. The volume of one corrugated pipe is increased and the volume of another is decreased to force the oil in corrugated pipes to flow through the orifices of partition, generating resistance. Its advantages are long service life, and low maching precision.
Description
The present invention is a kind of vibration damper, is a kind of dydraulic shock absorber 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.According to first phase report in March, 1997 in railway epoch, French General Electric Alstom also is a piston type hydraulic damper to China's distribution.
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, oil storage cylinder and coupling with the dydraulic shock absorber replacement that two sections bellowss, the tabula utmost point, 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.
Realize that best way of the present invention is with two sections identical going up on the both ends of the surface that bellowss (1) and following bellows (2) be welded in 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 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 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 (4)
1. hydraulic vibration damper of corrugated pipe, particularly a kind of dydraulic shock absorber that replaces piston type hydraulic damper to reduce mechanical vibration such as vehicle, machine.This vibration damper as shown in drawings, by up and down bellows (1), (2), diaphragm (3), upper head plate (5), lower end sheet (8), interior pipe (9), outer tube (11) and attachment pegs (14), (15) constitute up and down.It is characterized in that having replaced the to-and-fro motion of piston in oil cylinder, so can not lose efficacy, so the life-span is long because of the wearing and tearing leakage of oil with the flexible of bellows.The bellows inner and outer pipes all is a section bar, need not resemble fine finishing oil cylinder, piston, the piston rod, so cost is low.
2. vibration damper according to claim 1 is characterized in that having certain spring action, can design its spring rate as required.
3. vibration damper according to claim 1, it is characterized in that if in accompanying drawing oil hole (5) oiling it just produce thrust, oil suction produces pulling force, therefore, it can be used as pressurized strut (being also referred to as oil cylinder, jack) and uses, and its advantage is to have avoided the wearing and tearing and the fine finishing of piston and cylinder wall.
4. vibration damper according to claim 1 is characterized in that if external force is forced the inner and outer pipes relative movement, connects suitable valve at end plate up and down, and it just becomes an oil pump, and its advantage is to have avoided the abrasion and the fine finishing of displacement oil pump piston and cylinder wall.
