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.
In the prior art, piston body moves inside the plunger shaft of piston cylinder, and oil liquid is limited in plunger shaft and passes through work
The damping hole of cock body is swapped in piston body two sides, relatively simple for structure, and oil liquid is enclosed in plunger shaft, can not be to plunger shaft
Interior oil liquid such as is supplemented or is filtered at the processing.
Summary of the invention
The technical problem to be solved by the utility model is to provide one kind the oil liquid in plunger shaft can be carried out supplement or
The multi-runner type guider of processing.
The technical scheme in the invention for solving the above technical problem are as follows: a kind of multi-runner type guider, including piston
Cylinder, piston head, the piston head are equipped with the first cooperation boss, and the periphery cooperation of the piston cylinder and the first cooperation boss, which is constituted, lives
Chamber is filled in, secondary channels cylinder has also been arranged with outside the piston cylinder, the piston head is equipped with the second cooperation boss, and second cooperation is convex
Platform and the cooperation of secondary channels cylinder constitute the fluid infusion runner being arranged in outside plunger shaft, and the fluid infusion runner is connected to plunger shaft.
Compared with the prior art, the advantages of the utility model are: by the way that fluid infusion runner is arranged outside plunger shaft, and mend
Liquid stream road is connected to plunger shaft, by the oil liquid in fluid infusion runner being supplemented or being filtered to realize to the oil in plunger shaft
Liquid is supplemented and is purified, and the stability and service life of piston operation are improved.
As a kind of improvement of the utility model, the outer wall of the first cooperation boss is equipped with for the end for piston cylinder
The frustum section of importing and seal section with the end close-fitting of piston cylinder, by the improvement, frustum section is inserted for the end of piston cylinder
Enter and is oriented to, the end close-fitting of seal section and piston cylinder, so that piston cylinder and piston head sealing installation positioning, positioning are quasi-
Really, easy for installation, and since the sealing of piston head and piston cylinder cooperation is more demanding, therefore need to set the seal section of drum type brake.
As the utility model there are also a kind of improvement, the outer wall of the second cooperation boss is equipped with for for secondary channels cylinder
End import and the conical surface seal section with the end close-fitting of secondary channels cylinder, by the improvement, conical surface seal section is taper, secondary
For channel cylinder by insertion conical surface seal section and piston head close-fitting, accurate positioning is easy for installation.
As the utility model there are also a kind of improvement, the piston head circumferentially arranged with fluid infusion hole, the piston head
End is equipped with baffle, elastic component and fixing piece, and the fixing piece is located at the middle part of piston head, and the fixing piece will by elastic component
Baffle elasticity blocks on fluid infusion hole, and by the improvement, fixing piece blocks baffle on fluid infusion hole, when the oil in piston cylinder
Press through low, when oil pressure in secondary channels cylinder is greater than the sum of oil pressure and elasticity of elastic component in piston cylinder, oil liquid pushes baffle to beat
It opens, oil liquid is added in piston cylinder.
As the utility model there are also a kind of improvement, the end of the piston head is close equipped with the first sealing bulge loop and second
Bulge loop is sealed, the first sealing bulge loop is located at the path in fluid infusion hole, and the second sealing bulge loop is located at the major diameter in fluid infusion hole,
The first sealing bulge loop and the second sealing bulge loop offset with baffle, by the improvement, the first sealing bulge loop and the second sealing
Bulge loop cooperates with baffle to separate to the liquid in fluid infusion hole and piston cylinder.
