Description
Technical field
The utility model relates to a kind of isolation damper, and it is applicable to vehicle, also can be used for the field that construction engineering, machinery, weapons, space flight, electronics, chemical industry, instrument etc. need vibration damping.
Background technique
Buffer is various vehicles and machinery important components, is to absorb impact energy, relaxes the necessaries device of unnecessary impact, all uses widely in fields such as railway, highway, machinery, national defence, buildings.The high speed of railroad train and heavily loaded development trend require damping property, the cushioning effect of train in running to increase substantially, and equally also require the own wt of train progressively to alleviate.At present, the buffer of China railways train is mainly wanted rubber bumper, dry friction buffer, hydraulic spring buffer, form is more single, shortcomings such as the capacity that exists is low, endurance quality is poor, maintenance load is big, can not satisfy the requirement that China's relevant goods passenger vehicle carrying capacity improves, the train traction gross weight increases, because buffer capacity is low, the cup spring abrasion are fast simultaneously, also increased the damage frequency of buffer.Recent years, China introduced the comparatively advanced elastic cement buffer of external a kind of technology, particularly Ministry of Railways Qingdao four directions vehicle research institute and Polish KAMAX company cooperate, the research of domesticizing, document " research of elastic cement coupler draft gear and application progress ", author Zhang Younan, the specific rubber goods magazine of Huang Youjian etc., point out in fourth phase calendar year 2001 p57～59, the elastic cement buffer of its development does not reach the technical merit of external like product, the rail truck magazine of while data " the type selecting analysis of new type passenger car buffer " author Li Kexing, the automatic runback device of the elastic cement buffer that the 35th volume the 3rd interim demonstration March in 1997 is domestic is the spring that goes in ring, and causes structure comparatively complicated.Therefore the vehicle bumper of high performance-price ratio awaits further exploitation and development.
Also be badly in need of asking the damping buffer of high performance-price ratio in addition in the fields such as machinery, construction engineering.
Summary of the invention
The purpose of this utility model provides the two-cylinder type of a kind of a kind of highly energy-consuming that can be used for vehicle and machinery, good airproof performance, simple in structure, long service life high performance-price ratio from resetting elastic cement buffer.
A kind of two-cylinder type of the present utility model is from resetting elastic cement buffer as shown in Figure 1, it includes Master cylinder body, be arranged at the piston that can slide in the Master cylinder body, the piston rod that is connected with piston, and the Master cylinder body inner chamber elastic cement of filling, be characterised in that, the outer cover of described Master cylinder body 1 is provided with subsidiary cylinder 2, spacing faying surface between Master cylinder body 1 and the subsidiary cylinder 2 is arranged to rise the overlap joint table top 9 of position-limiting action, and the open-mouth end of Master cylinder body 1 is disposed with stuffing box gland 4 and end plug 5; One end of described piston 3 is connected with piston rod 7, the other end of piston rod 7 pass successively stuffing box gland 4 and end plug 5 center hole, stretch out outside the cylinder body with top cover 6 on the subsidiary cylinder 2 and be connected.Described overlap joint table top has been formed the spacing and member that resets certainly of the present utility model by the contexture of Master cylinder body 1 and subsidiary cylinder 2 at the volley jointly with piston rod 7 and elastic cement 8.
The bottom of the Master cylinder body 1 described in the utility model is provided with exhaust port 11.
The inner and outer circumferential lateral face of the Master cylinder body 1 open-mouth end stuffing box gland 4 described in the utility model respectively is provided with five cover seal rings 10, and with end plug 5 fixed positions, end plug 5 is threaded with Master cylinder body 1 usefulness.
Piston 3 described in the utility model is provided with the damping hole 13 that runs through piston, and the diameter of piston 3 forms damping gap 12 less than the internal diameter of Master cylinder body 1 between the two.
Subsidiary cylinder 2 described in the utility model is threaded with top cover 6 usefulness.
Be full of the elastic cement 8 of known high-compressibility, full-bodied semisolid viscous medium in the cavity of the Master cylinder body 1 described in the utility model.
A kind of two-cylinder type of the present utility model is to try hard to recommend outside to move down from the working principle of the elastic cement buffer that resets, piston motion extruding viscous medium elastic cement 8, make the viscous medium by damping hole 13 and damping gap 12, produce the damping of contracting of frictional damping and hole, consume the energy of vibration, owing to apply from the precompression that resets to buffer when installing, during piston extruding elastic cement, elastic cement also produces reaction force to piston, because the unbalance response of single rod of piston, when buffer is not subjected to extraneous power, buffer automatically resets rapidly, accept preparation for bearing to impact next time, elastic cement 8 flows from damping gap 12 and damping hole 13 simultaneously, further consumes and absorbs vibrational energy.Be characterized in that just compressive force is adjustable, rigidity is adjustable, rated impedance power is adjustable, can reset S. E. A. higher (more than 85%), freedom from repairs for a long time, long service life rapidly.
Compared with prior art, the advantage that has following aspect:
