Description
Technical field
The utility model relates to automobile absorber field, in particular to a kind of high sealing shock resistance supporting bead.
Background technique
Automobile is when by uneven road surface, although the shock-absorbing spring in suspension system can filter the vibration on road surface, bullet
Spring itself also has reciprocating motion, and damper is exactly for inhibiting this spring back and forth to jump.The structure of damper is band
Have in the piston rod insertion cylinder of piston, full of oil in cylinder.There is damping hole on piston, so that the two parts separated by piston are empty
Between in oil can complement each other.The working principle of damper is to work as phase occurred by vibration between vehicle frame and vehicle bridge or vehicle body and vehicle bridge
When to movement, the piston in damper is moved up and down, and the oil liquid in snubber cavity just repeatedly passes through different holes from a chamber
Clearance flow enters that another is intracavitary, and the friction between hole wall and oil liquid at this time and the intermolecular interior friction of oil liquid form damping force to vibration,
So that thump energy is converted into oil liquid thermal energy, then is dispersed into atmosphere by absorber.
Guider is one of the important part in damper, it plays guiding well to the movement of piston rod in damper and makees
With, guarantee piston ride comfort in the process of running, while during piston motion by the oilhole of guider by working cylinder
It is connected to oil storage cylinder.
Guider one end is set for providing the supporting bead of support force, existing supporting bead when being supported, due to
The machining accuracy of end face is different, carries out end face support cooperating with guider, when guider is by impact force, is easy to produce
Raw shake, causes guider inner sealing performance to decline, operation stability decline.
Summary of the invention
It is close inside guider to guarantee by force that the technical problem to be solved by the utility model is to provide a kind of stability of strutting system
The high sealing shock resistance supporting bead of sealing property and operation stability.
The technical scheme in the invention for solving the above technical problem are as follows: a kind of high sealing shock resistance supporting bead, packet
Ontology is included, one end of the ontology is support end face, and the support end face indent is equipped with and the annular of support end face coaxial line
Groove, the supporting surface that the groove of the annular will support end face hollow out to circularize, the outer diameter and support end of the groove of the annular
The diameter in face is close.
Compared with the prior art, the advantages of the utility model are: groove hollow out of the support end face by annular, and make
The outer diameter for obtaining annular groove is close with the support diameter of end face, so that being close to annular by the remaining supporting surface of groove hollow out
The supporting surface of line, so that original face support is changed to line support, support it is more stable so that guider by impact force when
Time is not likely to produce shake, improves the stability when inner sealing performance and operation of guider.
As a kind of improvement of the utility model, the center of the ontology is equipped with through-hole, and the support end face is close to through-hole
Place is equipped with the confined planes of annular, and the confined planes are arranged lower than supporting surface, by the improvement, when supporting surface generates deformation,
Confined planes are used to limit the depth capacity of supporting surface deformation, cause to deform due to excessive deformation to avoid supporting bead.
As the utility model there are also a kind of improvement, the groove includes the first tapered sidewalls and the second tapered sidewalls,
First tapered sidewalls are used to carry out transition to the bottom surface of supporting surface to groove, and second tapered sidewalls are used for confined planes
Transition is carried out to the bottom surface of groove, it, can be to avoid by the first tapered sidewalls of setting and the second tapered sidewalls by the improvement
Between supporting surface and the first tapered sidewalls, between confined planes and the second tapered sidewalls, the first tapered sidewalls and the second tapered sidewalls
Stress between groove floor is concentrated and causes to be broken.
As a kind of also improvement of the utility model, the gradient of first tapered sidewalls is less than the second tapered sidewalls
Gradient, by the improvement, the gradient of the first tapered sidewalls is smaller, can increase the elastically-deformable ability of supporting surface.
As the utility model there are also a kind of improvement, the other end of the ontology constitutes section from peripheral wall to end face, institute
The corresponding first tapered sidewalls setting in section is stated, by the improvement, section can reduce the wall thickness at supporting surface, improve supporting surface
Elastic deformation ability.
As a kind of also improvement of the utility model, the angle of the end face of the section and ontology is 30 °~40 °, is led to
The improvement is crossed, the gradient of section is slightly larger than the gradient of the first tapered sidewalls, on the one hand which can guarantee supporting surface
Elastic deformation ability, on the other hand can guarantee the support strength of supporting surface.
