Abstract
The present invention proposes a kind of new type vibration isolator, which solve the problem that existing vibroshock oil storage chamber forms bubble, including the guider of vibroshock, inner core, urceolus, a square ring is set up between described guider and inner core, square ring external diameter is less than urceolus internal diameter, and it is oil extraction ring that square ring and outer tube inner wall form small gaps.Present invention effectively prevents vibroshock oil emulsifying, vibroshock produces the phenomenons such as air pocket, idle running, abnormal sound, it also avoid the generation of oil leakage phenomenon at oil sealing simultaneously.
Description
Technical field
The present invention relates to vehicle shock absorber, be specifically related to a kind of new type vibration isolator.
Background technology
Vehicle shock absorber is a kind of damping element, is the rapid wear accessory during automobile uses, is also the weight of automotive suspension
Want one of element, to ride comfort, comfortableness, safety, the steering operation of running car and play decisive work by property
With.When vibroshock works, owing to connecting rod is in reciprocating motion state, have a small amount of vibroshock fluid and enter guider and oil sealing
Between gap in, these fluid can be back to oil storage chamber by the outage of guider.Owing to guider outage is from store oil
Chamber liquid level has certain difference in height, and fluid is instilled oil storage chamber by the outage of higher position can form bubble, and these bubbles can be with
Connecting rod and move back and forth entrance working chamber, cause vibroshock oil emulsifying, make vibroshock produce the phenomenons such as air pocket, idle running, abnormal sound,
Have a strong impact on vibroshock performance.
Summary of the invention
The technical problem to be solved is a kind of new type vibration isolator of design, and this vibroshock is it can be avoided that oil storage chamber shape
Become bubble, effectively prevent vibroshock oil emulsifying, make vibroshock no longer produce the phenomenons such as air pocket, idle running, abnormal sound.
For solving above-mentioned technical problem, the technical solution used in the present invention is: a kind of new type vibration isolator, including vibroshock
Guider, inner core, urceolus, between described guider and inner core, set up a square ring, square ring external diameter be less than urceolus internal diameter, square ring
Forming small gaps with outer tube inner wall is oil extraction ring.
Described square ring outside dimension is less than urceolus internal diameter 0.4～0.6mm.
Described square ring is compressing through mould by strip steel.
The present invention uses a kind of new type vibration isolator designed by technique scheme, has the advantages that
1. the present invention sets up a square ring device in damper structure, makes the fluid between guider and oil sealing flow to through outage
On square ring, oil extraction ring narrow and small between square ring and outer tube inner wall, slowly it flow to oil storage chamber along outer tube inner wall, it is to avoid because of fluid
Quickly instilling oil storage chamber and produce the problem of bubble, effectively prevent vibroshock oil emulsifying, vibroshock produces air pocket, idle running, different
The phenomenons such as sound；
2. owing to setting up a square ring, vibroshock oil storage chamber is divided into upper and lower two parts, only allows a small amount of fluid to be delayed by oil extraction ring
Slug flow leads to, and prevents from keeping flat because of vibroshock or being inverted, and a large amount of fluid of oil storage chamber enters the gap between guider and oil sealing, it is to avoid
Oil leakage phenomenon at oil sealing.
Accompanying drawing explanation
Fig. 1 represents the structural representation of a kind of new type vibration isolator of the present invention；
Fig. 2 represents the structural representation of square ring in Fig. 1；
Fig. 3 represents the plan structure schematic diagram of square ring in Fig. 1.
Detailed description of the invention
The structure of new type vibration isolator a kind of to the present invention illustrates below in conjunction with the accompanying drawings.
Seeing Fig. 1 to Fig. 3, one new type vibration isolator of the present invention, including inner core 7 and urceolus 8, guider 3 is arranged on inner core 7
Top, oil sealing 2 is arranged on the top of guider 3, and connecting rod 1 is inserted in inner core 7, on guider 3 by oil sealing 2 and guider 3
Outage 4 is distributed, between inner core 7 and connecting rod 1, forms working chamber 9, between inner core 7 and urceolus 8, form oil storage chamber 10.At inner core
Installing a square ring 5 between 7 and guider 3, the size of the outside dimension a of square ring 5 is very big to the influential effect of the present invention, square ring 5
Outside dimension a should be according to the size of the internal diameter size b of different outer barrel of absorber 8 depending on, square ring 5 uses strip steel by mould pressure
Make type, to guarantee that dimensional accuracy reaches requirement.
Preferably, the outside dimension a of described square ring 5 should be more smaller than urceolus 8 internal diameter size b, difference c 0.4～0.6mm it
Between, during design, the big I of the outside dimension a of square ring 5 is adjusted according to the internal diameter size b size of urceolus 8, to ensure difference
The size to fit of c.The reason using this size range is: square ring 5 outside dimension a is slightly less than urceolus 8 internal diameter size b, both
Between gap self-assembling formation oil extraction ring 6, make fluid slowly, smoothly by oil extraction ring 6.
When the value of c is less than 0.4mm, the outside dimension a of square ring 5 differs the least with the internal diameter size b of urceolus 8, i.e. oil extraction
Ring 6 gap is the least, and the impurity in fluid is easy to block oil extraction ring, affects the impact of performance of the present invention.
When the value of c is more than 0.6mm, the outside dimension a of square ring 5 differs greatly with the internal diameter size b of urceolus 8, i.e. oil extraction
Ring 6 gap is the biggest, it is impossible to make fluid slowly by oil extraction ring 6, the most directly instills oil storage chamber 10, forms bubble, make the present invention
Lost efficacy.
When the value of c is between 0.4～0.6mm, along with connecting rod 1 moves back and forth, a small amount of fluid in working chamber 9 enters and leads
Gap between device 3 and oil sealing 2, these fluid flow to square ring 5 by outage 4, then by oil extraction ring 6 along urceolus 8 inwall
Slowly flow into oil storage chamber.So, whole process reduces as far as possible and bubble occurs, it is to avoid vibroshock oil emulsifying, vibroshock
Produce the phenomenons such as air pocket, idle running, abnormal sound.
The present invention is a kind of new type vibration isolator, solves vibroshock oil storage chamber and is easily generated the problem of bubble, and then avoids
Vibroshock oil emulsifying, vibroshock produces the phenomenons such as air pocket, idle running, abnormal sound.This solution principle is simple, it is easy to manufactures, takes into account
Effect and cost, can apply with large-scale popularization.
