Specific embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model statement
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
Embodiment 1
As shown in Figure 1, a kind of damper cylinder structure with heat sinking function, including damper cylinder barrel 1, the damper cylinder
Piston 2 is provided in cylinder 1, the piston rod 3 for stretching out damper cylinder barrel 1 on the piston 2 is housed, dress is fixed on the piston rod 3
There is the dust cover 4 for covering 1 top of damper cylinder barrel, a circle cooling fin 5 is provided on the 1 lower part outer wall of damper cylinder barrel, when
When piston rod 3 is moved downwardly to extreme position, there are certain intervals between the dust cover 4 and cooling fin 5;Cooling fin 5 increases
The contact area of damper cylinder barrel 1 and air, so as to play good dissipate to fluid inside damper cylinder barrel 1 and damper
Heat effect, it is ensured that damper will not cause oil viscosity to be lower because temperature is too high, and comfort is deteriorated;
As shown in Figure 2,3, the utility model can be further depicted as, and the damper cylinder barrel 1 includes oil storage cylinder barrel 41
With the cushion cylinder 42 being sleeved in oil storage cylinder barrel 41, the piston 2 is arranged in cushion cylinder 42, the cushion cylinder 42
The rebound valve 43 for being communicated to oil storage cylinder barrel 41 in rod chamber is housed, the rod chamber and nothing of connection cushion cylinder 42 are housed on piston 2
The flowing valve 44 of rod cavity is additionally provided with compression valve 45 and recuperation valve between the rodless cavity of the cushion cylinder 42 and oil storage cylinder barrel 41
46;
When on the uneven road surface of vehicle traveling, when encountering bank, being jumped on wheel, damper is compressed, and piston rod 3 is to moving down
Dynamic, band piston 2 moves down;At this point, the fluid in 42 rodless cavity of cushion cylinder receives extruding, flowing valve 44 and compression valve 45 are together
It opens, a part of fluid flows to rod chamber through flowing valve 44, and the compressed valve 45 of another part fluid flows to oil storage cylinder barrel 41.Circulation
Valve 44 and compression valve 45 play throttling action to fluid, form shock absorbers compression damping force.When wheel, which is encountered, is jumped under hole, damper
It is stretched, piston rod 3 moves upwards, and band piston 2 moves up;At this point, rodless cavity receives stretching, rebound valve 43 and recuperation valve 46 1
It rising and opens, the fluid of 41 the inside of rod chamber and oil storage cylinder barrel is flowed into rodless cavity together through rebound valve 43 and recuperation valve 46, at this point,
Rebound valve 43 and recuperation valve 46 play throttling action to fluid, form damper and stretch damping force.In uneven road surface when driving, vibration damping
Device be in high-frequency stretch, compressive state, fluid during reciprocal flowing between valve friction work, lead to fluid
Temperature rises to very high, sees Fig. 3.
In the present embodiment, the cooling fin 5 is arranged on the outer wall of oil storage cylinder barrel 41, the cooling fin 5 and oil storage cylinder
The outer wall of cylinder 41 is an entirety;When processing oil storage cylinder barrel 41, gone out by outer surface turnery processing of the lathe in oil storage cylinder barrel 41
Cooling fin 5;Therefore, in order to be matched with actual processing technique, the cooling fin 5 is in star-arrangement.
