Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in further detail.
As it is shown in figure 1, one of the present utility model compensates damping shock absorber automatically, including guider 8, oil storage
Cylinder 9, working cylinder 10, piston rod 11, piston valve assembly 6 and base valve chip module 12；Described piston valve
Chip module 6 is fixed on the lower end of piston rod 11, is nested in working cylinder 10 internal, is divided into epicoele and cavity of resorption；
Described working cylinder 10 is placed in oil storage cylinder 9, is shoe cream room between working cylinder 10 and oil storage cylinder 9, working cylinder 10 times
End is equipped with base valve chip module 12；Described guider 8 is installed on the upper end of working cylinder 10.
When piston rod 11 moves downward, piston rod 11 gradually stretches in working cylinder 10, and piston rod 11 is to base valve
Chip module 12 moves, and epicoele volume increases, and cavity of resorption volume reducing, the part fluid in cavity of resorption is forced to discharge.
Oil flows through piston valve block assembly 6 in cavity of resorption, flows in epicoele, due to stretching into of piston rod 11 so that it is
Volume in working cylinder 10 increases, and makes the oil mass in the oil mass unnecessary inflow epicoele discharged in cavity of resorption, and this is at present
In chamber, some fluid is in base valve chip module 12 flows to oil storage cylinder 9；When piston rod 11 moves upward
Time, the oil flows through piston valve block assembly 6 in epicoele, flow in cavity of resorption, the fluid in oil storage cylinder 9 flows through the end
Seat valve chip module 12, flows in cavity of resorption.
As in figure 2 it is shown, piston rod 11 lower center has a long blind hole 1, piston rod 11 sidewall has one
Fluid through hole 3 connects with long blind hole 1.The position of fluid through hole 3 be positioned at long blind hole 1 top slightly under position, excellent
Select the scheme to be, be positioned under top 5.The quantity of long blind hole 1 is not limited fixed, and preferred version is 1.
As it is shown in figure 1, also include rotating pin 4 and a thermo bimetal 5, described rotating pin 4 is positioned at long blind
In hole 1, a length of 40-70 of long blind hole, preferred version is 50.Rotating pin 4 can be along with the double gold of heat
Belong to the deformation rotation of 5 and rotate；Gap between rotating pin 4 and long blind hole 1 is 0.1-1, and preferred version is
0.5㎜.The a diameter of 5-10 of rotating pin 4, a length of 40-70, preferred version is diameter 6, a length of
50㎜。
As it is shown on figure 3, the center of rotating pin 4 has an oil passage 2, sidewall has a compensation hole 7 and its
Connection, the position compensating hole 7 is positioned at the top of oil passage 2, and the diameter compensating hole 7 is less than the straight of fluid through hole 3
Footpath, when normal temperature (when both oil liquid temperature is 25 °), compensates hole 7 and fluid through hole 3 and partially overlaps portion
Point；The lower end of rotating pin 4 has a groove, and the width of groove is equal to the thickness of thermo bimetal, the height of groove
Degree, equal to the height of thermo bimetal 5, by one end of thermo bimetal during installation, inserts in groove, is allowed to fixing and connects
Connect, it is also possible to fix in a groove by the way of welding.
As shown in Figure 4, thermo bimetal 5 is helical structure, and one end is fixed on rotating pin 4, and the other end is fixed
On piston valve assembly 15.Thermo bimetal 5 peripheral diameter is 15-25, and thickness is 5-10, preferred version
For diameter 20, thickness is 8.One end of thermo bimetal 5 by being secured in being stuck in groove, the other end
Being fixed on piston valve assembly 6, preferred version is for being welded to connect.The material of thermo bimetal 5 is had by two-layer
The metal or alloy of different heat expansion coefficient is combined into.It is swollen that a constituent element layer in thermo bimetal 5 has low heat
Swollen coefficient, for passive layer；Another constituent element layer has high thermal coefficient of expansion, for active layers.Passive layer uses
Containing Ni34～50% because of tile-type alloy；Active layers then use pyrite, nickel, Fe-Ni-Cr, Fe-Ni-Mn and
One in Mn-Ni-Cu alloy.Such as model uses 5J1380, owing to thermo bimetal can allow producer direct
Customized, so not limiting according to vibroshock use difference.
Under room temperature working environment, both oil temperature was 25 °, when thermo bimetal 5 is normal condition, adjusted during installation
Good position, makes rotating pin 4 be positioned in long blind hole 1, compensating on hole 7 and piston rod 11 on rotating pin 4
Fluid through hole 3 partially overlaps part, as it is shown in figure 5, intersection is fluid circulation area.At this moment live
Filling in when moving up and down, the fluid in working cylinder 10 regulates epicoele and cavity of resorption not only by piston valve assembly 6
In fluid, have part fluid also fluid can be made to flow through compensation hole 7 by the oil passage 2 in rotating pin 4
Intersection with fluid through hole 3.At this moment circulation area is intermediate value, and damping force is identical with standard value.
When oil liquid temperature raises, can be that ambient temperature causes oil liquid temperature rising can also be movement time
Long causing temperature to raise, because oil liquid temperature raises, oil viscosity reduces, and causes damping force to reduce, this
Time piston rod when moving up and down, damping force is less than standard value, causes the handling of vehicle and comfortableness not
Rationally, owing to present invention employs thermo bimetal, when oil temperature raises, as shown in Figure 4, thermo bimetal 5 meeting
Rotate clockwise, drive rotating pin 4 to rotate together, make the intersection area of compensation hole 7 and fluid through hole 3
Reduce, at this moment can increase the damping force of vibroshock, make the part damping force reduced because of high oil temperature be mended
Repay, make damping force identical with mark value.
When oil liquid temperature reduces, because oil liquid temperature reduces, oil viscosity increases, and causes damping force to increase,
At this moment piston rod is when moving up and down, and damping force is greater than standard value, the thermo bimetal used by the present invention,
When oil temperature reduces, as shown in Figure 4, thermo bimetal 5 can rotate counterclockwise, and drives rotating pin 4 to rotate together,
The intersection area making compensation hole 7 and fluid through hole 3 increases, and at this moment can reduce the damping force of vibroshock, make
Because the part damping force of the too low increase of oil temperature reduces, make damping force identical with mark value.Enhance vehicle
Handling and comfortableness, simple in construction, effective.
It should be noted that, embodiment described in the utility model is only its optimal way, to belonging to this
The general idea of utility model, and it is only obvious change, protection of the present utility model all should be belonged to
Within the scope of.
