Description
Technical field
The present invention relates to automobile absorber field, and in particular to a kind of to have the big damping for damping diclinic hole piston valve system
Device.
Background technology
Concussion when damper is mainly used to suppress to rebound after spring shock-absorbing and the impact from road surface.By not level road
During face, although shock-absorbing spring can filter the vibrations on road surface, but spring itself also has a reciprocating motion, and damper be exactly for
Suppress this spring jump.Damper is too soft, vehicle body will vertical bounce, damper can bring about very much too big resistance firmly,
Hinder spring normal work.And the circulation valve portion of its upper piston area is functionally to play one-way flow in traditional damper
The effect of valve, the same rebuilt valve of its structure, but this structure is not suitable for the damper of big resistance to compression pression.
The content of the invention
The technical problems to be solved by the invention be directed to above-mentioned the deficiencies in the prior art,
A kind of damper for having and damping diclinic hole piston valve system greatly is provided.
To achieve the above object, the invention provides following technical scheme：One kind has big damping diclinic hole piston valve system
Damper, including oil storage cylinder is full of in damper special oil, the oil storage cylinder in the oil storage cylinder and is provided with working cylinder, described
Working cylinder one end is provided with the middle of guide valve, the guide valve provided with the compression valve other end and is equipped with piston rod, and the piston rod can
It is axially moved relative to working cylinder, the piston rod passes through close to one end of compression valve provided with valve assembly, the oil storage cylinder is restored
Spring is connected to piston rod, and the piston rod is connected with suspension ring rubber relative to the other end that valve assembly one end is restored in setting and served as a contrast
Set, it is characterised in that：The recovery valve assembly includes recovery valve body, and described recovery valve body one end, which is provided with, restores valve guard,
The other end is provided with circulation valve guard, provided with recovery valve block, the flowing valve between the recovery valve guard and recovery valve body
Flow- through valve plate is provided between limiter and recovery valve body, the rebuilt valve body phase is respectively arranged on the left side and the right side to piston rod through multiple
First slanted channel of former valve body and at least one second slanted channel.
A kind of above-mentioned damper with big damping diclinic hole piston valve system can be further arranged to：The recovery valve body
Two ends are being equipped with consistent with the first slanted channel and the second slanted channel quantity slit at recovery valve block and flow- through valve plate
Mouthful.
A kind of above-mentioned damper with big damping diclinic hole piston valve system can be further arranged to：Described first is oblique
Passage and the second slanted channel are connected with close to the gap for restoring valve block and flow- through valve plate one end respectively.
Using above-mentioned technical proposal, the course of work of piston valve system and normal piston valve system phase when the piston is moving up
Together, when piston low speed is moved downward, the fluid of piston cavity of resorption is oblique through first again by restoring the recovery valve block gap on valve block
Epicoele formation low speed damping characteristic is flowed into passage, when piston middling speed is moved downward, the fluid of piston cavity of resorption is except by multiple
Recovery valve block gap on former valve block flows into most of acted on by the second slanted channel outside epicoele and forced in the valve block group of top
Valve block is bent upwards to form passage, and when high speed piston is moved downward, the second slanted channel also functions to crown_interception, now damps
Characteristic depends on specific second slanted channel quantity.
Beneficial effects of the present invention are：By setting the first slanted channel and the second slanted channel, change second oblique logical
The quantity in road can be designed that the damper of required damping characteristic, highly versatile.
The present invention is described in further detail with reference to the accompanying drawings and examples.
