Abstract
The utility model relates to the improvement of an existing oil-gas type damper; namely, the lower cavity of the existing oil-gas type damper is changed into two cavities separated by an oil seal, and the lower end of a cylinder is provided with an air hole; when the exchanging volumes of the working cavities are not equal, the oil seal automatically adjusts and fills under the action of the unequal pressures. The utility model has the advantages of large oil chamber, long working cavity, soft damping, oil saving and low cost.
Description
The utility model is the improvement that belongs to vibration damper.
Being of long duration of vibration damper, kind is also a lot, but has many deficiencys.Such as the hydraulic type vibration damper, its complex structure, cost height; Oil gas formula vibration damper requires gas filling technology and strict sealing technology accurately, its processing difficulties in manufacture process.The utility model is on the basis of existing vibration damper oil gas formula vibration damper to be transformed, and is designed to novel oil gas formula vibration damper.This just can fundamentally improve the phenomenon that existing vibration damper active chamber weak point, damping error, hydraulic oil easily leak.
The purpose of the utility model design is to be to design novel oil gas formula vibration damper to reach existing vibration damper of generation, makes its grease chamber big, and active chamber is long; It is soft, sensitive to work; Fluid is difficult for leaking, and can reduce with oil and reduce cost.
For achieving the above object, the utility model is provided with pore, filter cleaner and oil sealing in the cylinder barrel bottom.When piston when cavity of resorption is worked, fluid enters epicoele by relief valve on the piston and one-way valve; When piston returned, owing to be subjected to the control of one-way valve, fluid can only enter lumen lentamente.It is additional that oil sealing is adjusted by spring force under the action of pressure that two chamber swept volumes do not wait voluntarily.
Below in conjunction with accompanying drawing the utility model is described in detail.
Accompanying drawing is that structure of the present utility model is always schemed.
With reference to accompanying drawing, piston rod (2), oil sealing (3), piston (5), oil sealing (7) are divided into epicoele (4), lumen (6), cavity of resorption (8) with cylinder barrel (1); Several fixedly relief valve of aperture (17) and one-way valves (18) are arranged on the piston (5); Be full of hydraulic oil in epicoele (4) and the lumen (6); Attachment eye (14), pore (9), filter cleaner (10) and spring (16) are arranged at cylinder barrel (1) bottom.Spring (11) is enclosed within outside the cylinder barrel (1), and the one end is fixed on the back-up ring (12), and the other end connects formation to be supported with back-up ring nut (15).
Not only the grease chamber is big, active chamber is long, damping is soft for the utility model, sensitive, leakage loss is little, and economizes with oil, structure, technology are simple, cost is low.
Claims (4)
1, a kind of oil gas formula vibration damper is made up of cylinder barrel (1), piston (5), piston rod (2), oil sealing (7), oil sealing (3), pore (9), filter cleaner (10) etc., and it is characterized in that: there is pore (9) cylinder barrel (1) lower end, and filter cleaner (10) communicates with the external world; Oil sealing (3) and oil sealing (7) are with the part of piston (5), piston rod (2), and hydraulic oil is sealed in the cylinder barrel (1).
2, vibration damper according to claim 1 is characterized in that: the oil sealing (7) in the cylinder barrel be an oil resistant rubber, and it is mobile under the pressure effect that lumen (6) and cavity of resorption (8) do not wait.
3, vibration damper according to claim 1 is characterized in that: the bottom of cylinder barrel (1) has a pore (9) to communicate with the external world.
4, vibration damper according to claim 3 is characterized in that: be mounted with the filter cleaner (10) of filtered air in the pore (9), filter cleaner is made by dustproof, gas permeable material.
