Abstract
The utility model discloses a hydraulic solderless vibration damper, comprising a protecting cover, a telescopic rubber dirt-proof boot, a piston rod guiding support, a piston rod, a pressure cylinder, a piston assembly, a bottom valve assembly, and an oil storage cylinder. Wherein the inner bottom portion of the protecting cover is provided with the piston rod guiding support of which the upper portion is covered by the telescopic rubber dirt-proof boot. The piston rod passes through the telescopic rubber dirt-proof boot and the piston rod guiding support to reach the inside of the pressure cylinder with the piston assembly which is arranged on the lower end. The oil storage cylinder is arranged on the outside of the pressure cylinder and the bottom valve assembly is arranged at the bottom of the pressure cylinder. The utility model is characterized in that the deformation caused by the use of welding, cleaning and detecting procedures is reduced, leakage defects are stopped, and procedures are decreased. The hydraulic solderless vibration damper with the good symmetry of the cylinder body reduces the asymmetry and enhances the concentricity of the cylinder body pressure. The utility model also reduces the extrusion and the deflection friction of the movable sealing ring caused by different concentricity.
Description
Technical field
The utility model relates to a kind of dydraulic shock absorber, and specifically a kind of locomotive, vehicle are with there not being the welding vibration damper.
Background technique
At present, what locomotive, vehicle hydraulic vibration damper adopted is the vibration damper of welding type, the detection operation is cleaned in distortion and the increase of adopting welding manner to cause easily, easy seepage, cylinder body is asymmetric, the concentricity of cylinder pressure is not high, because of the extruding of the dynamic seal ring that nonconcentricity caused and deflection frictional ratio bigger.
The model utility content
Technical problem to be solved in the utility model provides a kind of hydraulic pressure does not have the welding vibration damper, can solve defective and problem that prior art exists.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of hydraulic pressure does not have the welding vibration damper, structure comprises protective housing, telescopic boot seal, piston rod guide, piston rod, pressure cylinder, piston, bottom valve, oil storage cylinder, be provided with piston rod guide at the protective housing inner bottom part, the piston rod guide top covers with telescopic boot seal, interior its lower end of arrival pressure cylinder was equipped with piston assembly after piston rod passed telescopic boot seal and piston rod guide, the pressure cylinder outside is an oil storage cylinder, and the bottom valve assembly is installed in the bottom of pressure cylinder.
Described telescopic boot seal is connected with piston rod guide by locking blind nut, pad, O shape circle.
Seal with door, nut, seal ring between described piston rod guide and the piston rod.
Described piston assembly comprises spool and valve spring, and spool places and is installed on piston assembly inside in the valve spring, and the adjustment screw is set above again.
Described bottom valve assembly comprises foot valve seat, spool, valve spring, and the foot valve seat spool interior with placing valve spring is installed on the bottom valve piston, and spool is provided with the bottom valve lid with adjusting the screw adjustment below the bottom valve piston.
Described piston is connected with piston rod by piston ring, O shape circle, seal ring, packing washer.
1, there is not welding, outward appearance U.S., modification is few, can increase the service life.
2, cylinder body is to weighing up, reduced the concentricity of the motive sealing cylinder that causes because of nonconcentricity, reduced the extruding of the dynamic seal ring that causes because of nonconcentricity and be partial to very much friction, improved quality of product, can reach and per hour use in the example of the high speed more than the 250 kilometers car.
3, cylinder body drawn, extruding has increased cylinder body tightness and intensity and can reach at express locomotive more than 250 kilometers per hour, uses on the vehicle.
4, there is not the welding dydraulic shock absorber, main overall target is asymmetric, the asymmetric rate of the standard laid down by the ministries or commissions of the Central Government is 10%, does not have a welding dydraulic shock absorber is asymmetric only to differ from 0.4%, and is all asymmetric below 5%, it is required steadily to be used for the routine car operation of high speed, comfortable, safe requirement has satisfied speed-raising locomotive fully, the needs of vehicle, and arranged super working life.
5, reduce the distortion and the cleaning that cause because of welding and detect operation, stop seepage defect, reduced operation and lowered the one-tenth rate, increase the service life.
6, selected for use at present for the most collapsible sealing of science at present, in the particular range application except the relative displacement of piston rod with respect to seal ring, abrasion have been reduced, improved sealing, safety there is relative assurance, can prolong the working life of seal arrangement greatly, thereby prolong the working life of vibration damper.
