Description

A kind of damper link of safety noise reduction

Technical field

The utility model is related to a kind of damper accessory, more precisely, being a kind of damper link of safety noise reduction.

Background technology

Damper, concussion when being mainly used to suppress to rebound after spring shock-absorbing and the impact from road surface.By uneven During road surface, although shock-absorbing spring can filter the vibrations on road surface, but spring itself also has reciprocating motion, and damper is exactly to use To suppress this spring jump.Damper is too soft, vehicle body will vertical bounce, damper can bring about very much too big resistance firmly Power, hinders spring normal work.In the retrofit process on suspension, hard damper will mutually arrange in pairs or groups with hard spring, And the hardness of spring and car weight are closely bound up, therefore heavier car typically uses harder damper.Connect with drawing shake bent axle Device, for the twisting vibration (i.e. the impulsive force of bent axle subject cylinder igniting and the phenomenon that twists) for the bent axle that contends with.

Connecting rod is the critical piece of damper, and cushioning effect is played in damper, but finds to pass through at this in use Often there is overcast noise, be found to be connecting rod and dust cover, connecting rod and guide holder, sleeve and guide holder etc. through analysis draws due to rubbing Rise.The connection of existing connecting rod is as shown in figure 1, the contact area of reduction con-rod only end face and connector is rubbed with reducing as far as possible Wipe, but when connecting rod is by radial direction twisting resistance, because the weakness at this will certainly cause the discomfort of passenger, then bear to turn round When turning power and reaching certain amount, connecting rod needs to change.

Utility model content

The utility model is mainly the technical problem solved present in prior art, so as to provide a kind of subtracting for safety noise reduction Device connecting rod is shaken, prolonged strong twisting resistance can be born.

Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：A kind of safety noise reduction Damper link, including con-rod only, rubber ring, connector, damping spring I, bearing plate, damping spring II, spindle nose.Connecting rod The two ends of body 1 are spindle nose, and spindle nose is equipped with damping spring II in con-rod only one end.It is cased with being used for and automobile outside spindle nose The connector of suspension connection.Con-rod only is hollow body, and the wall body of con-rod only 1 also wraps up rubber ring.In connector in the middle of spindle nose Both sides are additionally provided with a pair of damping spring I, and connecting rod is in routine in use, damping spring II is acted on connector, so as to avoid acutely Vibrations cause strong noise, when running into special circumstances and needing to bear strong twisting resistance to cause radial force, spindle nose two ends unbalance stress, Damping spring II extrudes bearing plate, and damping spring I is many one heavy cushioning effects, while spindle nose two ends stressing conditions can also be balanced, Ensure driving safety.

The con-rod only is hollow cylinder, and its wall body is uniformly provided with circular hole, because connecting rod is dipped in damper fluid, Circular hole is set to ensure the lubrication between con-rod only and rubber ring, moreover it is possible to mitigate connecting rod weight.

The connector formation cover body, and the rubber ring with con-rod only outer wall is not contacted, and lubricating oil is coated in its gap, The friction of con-rod only end face and connector can effectively be reduced.

The damping spring II is welded in spindle nose, and one end welding and con-rod only end face, and the other end is welded in spindle nose Jackshaft is close to con-rod only side.The damping spring I sets mobilizable bearing plate close to damping spring II sides.

The rubber ring rubber, which is poured, to be formed, and pore is full of in its wall body so that oil can be distributed on entirety, rubber ring also Provided with limited block, its limited block is poured and integral with rubber ring by rubber.

Hard metal material is inserted with the limited block, hard metal piece sets flange, enhancing limit close to con-rod only side The hardness of position block, so does on reduction stop collar block welding connecting rod and causes rod surface to be heated tissue change, it is to avoid connecting rod table Face local heating deforms, and rubber ring mitigates connecting rod weight.

The con-rod only is additionally provided with annular groove with limited block corresponding position, the flange kissing with hard metal piece bottom Close.

The damper link of safety noise reduction of the present utility model has advantages below：Shaft covers rubber ring, and con-rod only is Hollow cylinder, its wall body is uniformly provided with circular hole, reduces and the dual reduction resonance of spring is set at the friction of connecting rod and sleeve, its spindle nose Caused noise so that connecting rod, which can not only bear axial compressive force, can also bear radial pressure, extends the service life of damper, increases The practicality of strong damper.
