Description

A kind of damper of automobile using adjustable damping hardness
Technical field
It the utility model is related to technical field of automobile accessories, more particularly to a kind of damping of automobile using adjustable damping hardness Device.
Background technology
Damper (Absorber), concussion when being mainly used to suppress to rebound after spring shock-absorbing and impact from road surface, When by uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, spring itself also has reciprocating motion, and subtracts For shake device for suppressing the jump of this spring, damper is too soft, vehicle body will vertical bounce, damper can bring about very much firmly Too big resistance, hinder spring normal work.In the retrofit process on suspension, hard damper will be with hard spring Mutually arrange in pairs or groups, and the hardness of spring and car weight are closely bound up, therefore heavier car typically uses harder damper.It is bent with drawing shake The device that axle connects, for the torsional shaking for the bent axle that contends with(That is the impulsive force of bent axle subject cylinder igniting and the phenomenon that twists).
, can not be to the hardness of damping but existing automobile damper is in use there is in place of some shortcomings It is adjusted, secondly the flexible of piston rod easily takes the lubricating oil inside pressure measuring cylinder out of, and the stability used is relatively low.
Utility model content
The purpose of this utility model is to solve shortcoming present in prior art, and a kind of automobile using proposed is adjustable The damper of damping hardness.
To achieve these goals, the utility model employs following technical scheme:A kind of automobile using adjustable damping is hard The damper of degree, including upper lift ring, the upper lift ring are fixedly connected by contiguous block with the spring base on piston rod top, the work Stopper rod is socketed in pressure measuring cylinder, is socketed with spring, the pressure measuring cylinder bottom on the piston rod between spring base and pressure measuring cylinder End is connected with lower lift ring by connecting rod, and one end that the piston rod is located in pressure measuring cylinder is fixed with sealing-plug, and sealing-plug Surrounding is socketed with the second sealing ring, and the pressure measuring cylinder bottom is provided with bottom valve, and venthole is offered in bottom valve, described close Sealing gasket is connected with by threaded rod at blocking inside center, the sealing-plug is internally provided with airway tube.
As further describing for above-mentioned technical proposal:
The upper lift ring is identical with lower lift ring structure, equal in magnitude, and upper lift ring is on same vertical curve with lower lift ring.
As further describing for above-mentioned technical proposal:
The junction of the piston rod and pressure measuring cylinder is provided with the first sealing ring.
As further describing for above-mentioned technical proposal:
The piston rod and pressure measuring cylinder are cylindrical structural, and the diameter of piston rod is less than the diameter of pressure measuring cylinder.
As further describing for above-mentioned technical proposal:
The airway tube is provided with two altogether, and two airway tubes are symmetrical on sealing-plug vertical center line.
In the utility model, the damper of the automobile using adjustable damping hardness first, the bottom for passing through pressure measuring cylinder is set There is bottom valve, the venthole in bottom valve is opened in the control of rotating base valve, so as to reduce the air pressure inside pressure measuring cylinder, reduces piston Suffered resistance is shunk, reduces shock-stiffness, secondly airway tube is provided with the sealing-plug of piston rod one end connection, passes through Rotating threaded rod can seal airway tube by sealing gasket, so as to control the hardness of damping, then have the company of piston rod and pressure measuring cylinder The place of connecing is provided with the first sealing gasket, can prevent the lubricating oil inside pressure measuring cylinder from spilling, and improves the stability used.
