Embodiment
Below against accompanying drawing, by the description to embodiment, embodiment of the invention is made further details of
Explanation.
Automotive steering reservoir of the present invention, as shown in figure 1, including tank body, the tank body is divided into upper tank body 2 and lower tank 1, on
Tank body 2 is provided with cover 3, and lower tank 1 is provided with oil return opening 5 and oil-out 6.As shown in Fig. 2 it is communicated with oil return opening 5
Tank body oilhole, the oilhole include oilhole first paragraph 51 and oilhole second segment 53, and oilhole first paragraph 51 is close to tank body, and aperture is more than
The aperture of oilhole second segment 53, connected between oilhole first paragraph 51 and oilhole second segment 53 by gradual change trumpet-like transition section 52.
Hydraulic system damping can be increased using the oilhole in the change aperture, reduce system pulses, reduce the effect of abnormal sound, save increasing
Install additional with choke valve or lengthen oil return pipe, it is so not only convenient for assembly and cost can be reduced.
In the present invention, be located at the reaming section 54 that is connected with oilhole second segment 53 in the outer end of oil return opening 5, reaming section 54 due to
The outside aperture in the junction of oilhole second segment 53 gradually broadens, can relatively reduced front and rear pressure difference, ensure liquid flow stability, enter one
Step reduces system pulses, reduces the effect of abnormal sound.
The cover 3 of the automotive steering reservoir is connected with tank mouth 8 by screw thread, as shown in Fig. 2 and cover 3 with
Sealing ring 9 is provided between tank mouth 8, using sealing ring 9, realizes radial seal therebetween, external diameter and the cover 3 of sealing ring 9
Threaded end (TE) minor diameter fit, when threaded cap is slowly screwed, and pressure is acted on sealing ring 9, one is formed at sealing relatively
The pressure curve answered, sealing ring 9 keep a certain size compression stress, can improve the sealing property of fluid reservoir.
Tank mouth 8 is provided with pouring orifice 10, and the lower end of pouring orifice 10 is connected with the oil guide plate 11 of oil leak.Oil guide plate 11 is shower nozzle
Shape, is provided with multiple oil leaking holes on the lower surface of oil guide plate 11, and upper surface is in the arcwall face tilted down.Oil passes through pouring orifice 10
Enter through oil guide plate 11 in cavity, fluid flows slowly into, and reduces fluid foamed phenomenon.Injection-molding surfaces are blocked caused by return pressure
Impact, this device can be greatly attenuated oil return ability under extreme conditions, and its car is rocked, and fluid is splash to be stopped by oil guide plate 11,
Avoid fluid from entering in cover 3, avoid permeability, improve tank body overall sealing performance significant effect.The upper surface of arcwall face can make
After oil gas assembles on end face, slid along curved end to tank body.
In the present invention, the spoiler 12 of cylindrical structure is connected with the interior bottleneck of upper tank body 2, spoiler 12 plays flow-disturbing work
Weaken mobility by interacting with, fluid, reduce because fluid rock caused by vortex and bubble, solve because rocking larger draw
Rise cavitation erosion, power-assisted fail the problem of, also to a certain extent hinder fluid splash, reduce oil leak probability.
Fluid reservoir of the present invention, the bottom surface of lower tank 1 are provided with the filter 13 connected with oil return opening 5, and the fluid of backflow passes through
Filter 13 enters in tank body after filtering.The filter being tightly connected with inner wall surface thereof is provided with lower tank 1, filtering Board position is higher than
The position of oil-out 6, ensure that fluid is flowed out by oil-out 6 again after filtering, ensure that fluid effectively filters, then carry out power-assisted
Steering-effecting, lift steering performance.
Preferably, reinforcement 7 is equipped with tank body junction in oil return opening 5 and oil-out 6, to strengthen its structural stability
Energy.Turnable stock solution tank material is preferably using being PA66+GF33, and injection molding, tension anti-tensile and shock resistance are good.
Automotive steering reservoir of the present invention, by changing the oilhole shape of oil storage tank oil return opening 5, it can reach reduction system arteries and veins
Punching, the effect of abnormal sound is reduced, be increased without choke valve or lengthened hose, it is so convenient for assembly, reduce cost；Oil guide plate is set
11 and spoiler 12 may also function as reduction rock caused by fluid pulse, avoid producing and be vortexed and bubble, prevent fluid from cover 3
Place is oozed out, and reduces oil leak probability.The automotive steering reservoir is simple in construction, and process and assemble is convenient, and cost is low, and performance and
Structural behaviour is good, can obtain good automobile assisted power steering performance.
The present invention is exemplarily described above in conjunction with accompanying drawing, but the present invention is not limited to aforesaid way, only
To use the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress or directly apply to other occasions
, all fall within protection scope of the present invention.
