Description
Technical field
The utility model relates to auto parts and components, more particularly relates to be applied in a kind of oil storage tank that turns in the automobile hydraulic electric power steering system.
Background technique
The automobile hydraulic electric power steering system is the oil pressure work that produces by engine-driven steering power pump, and the stream of steering oil is provided with oil storage tank, and steering oil refluxes at a high speed and enters oil storage tank.That uses at present turns to oil storage tank, its profile as shown in Figure 3, the direction of arrow has illustrated the liquid flow direction in this oil storage tank tank body.After steering oil is entered by filler opening 1, without any directly flowing to oil outlet 2 with stopping, steering oil is at the inner eddy current that forms of oil storage tank, be easy to generate bubble, bubble sneaks into steering oil after oil outlet enters steerig pump, cause the spot corrosion of steerig pump inner plenum noise and oil pump wall, not only influence performance but also reduced working life.Simultaneously, hinder flowing of steering oil again at the inner bubble generation pipeline noise that forms of pipeline.
The model utility content
The technical problems to be solved in the utility model is: the existing oil storage tank that turns to is after steering oil is entered by filler opening, without any directly flowing to oil outlet with stopping, steering oil forms eddy current in the inner meeting of oil storage tank, be easy to generate bubble, bubble is sneaked into and is turned to liquid after oil outlet enters steerig pump, cause the spot corrosion of steerig pump inner plenum noise and oil pump wall, not only influence usability but also reduced working life.
For solving the problem that prior art exists, the technological scheme that the utility model adopted is:
Increase the eddy current segmenting device on the stream that turns to oil storage tank return opening and oil outlet, described eddy current segmenting device links to each other with dividing plate with the oil storage tank skin respectively, turns to oil storage tank to be split into oil back chamber and goes out oil pocket.
The steering oil outflow opening that is positioned at oil back chamber and goes out oil pocket one side is set respectively on the described eddy current segmenting device.
Steering oil outflow opening on the described eddy current segmenting device that is positioned at oil back chamber one side is a plurality of erose little outlets, is positioned at the as a whole outlet of steering oil outflow opening on the eddy current segmenting device of oil pocket one side.
Be equipped with the eddy current separating device on the steering oil outflow opening on the described eddy current segmenting device that is positioned at oil pocket one side and make all-in-one-piece oil return filter screen.
Like this, after steering oil entered oil back chamber from return opening, owing to the barrier effect of the steering oil outflow opening on the eddy current segmenting device that is positioned at oil back chamber one side, steering oil was that the eddy current separating device is separated, and because a plurality of oil outlet mean allocation, steering oil is cushioned, thereby can not form eddy current in oil storage tank inside, thereby the bubble that produces is reduced to minimum degree, behind the steering oil outflow opening, steering oil merger again flows to out oil pocket together, finally flows out from oil outlet.The steering oil flow direction greatly reduces the stirring degree of oil outlet part through twice change, make fuel-displaced steadily, bubble reduces.
The utility model adopts technique scheme, on the basis of the monnolithic case that does not change oil storage tank, setting by the internal vortex segmenting device, can reduce the formation eddy current of oil storage tank inside effectively, reduce the generation of bubble, and effectively reduce the spot corrosion of the noise and the oil pump wall of oil pump inside, thereby improve steering oil pump performance and working life.

Embodiment
Contrast Fig. 1, Fig. 2 below,, embodiment of the present utility model is further described by description to embodiment.
Arrange that for cooperating car load present embodiment does not change the monnolithic case that turns to oil storage tank.
Present embodiment is to increase eddy current segmenting device 8 on the stream of return opening 2 that turns to oil storage tank 1 inside and oil outlet 4 to what prior art made improvements;
Eddy current segmenting device 8 links to each other with dividing plate 6 with turning to oil storage tank skin 7 respectively, and turnable stock solution tank 1 is split into oil back chamber 3 and goes out oil pocket 5;
The steering oil outflow opening 10 that is positioned on the eddy current segmenting device 8 of oil back chamber 3 one sides is the little outlet of 11 round structures, and the steering oil outflow opening 9 that is positioned on the eddy current segmenting device 8 of oil pocket 3 one sides is the integrated type outlet of a semicircular structure;
Steering oil enters oil back chamber 3 by return opening 2, owing to enter the steering oil of oil back chamber 3 is that eddy current separating device 8 is separated, and steering oil outflow opening 10 mean allocation of a plurality of little outlets are arranged, reduced the eddy current degree of fluid at oil outlet, thereby can not form eddy current, thereby reduce the generation of bubble in the oil storage tank in oil storage tank inside.
Enter fuel-displaced chamber 5 after steering oil process steering oil outflow opening 10 mean allocation.
The steering oil outflow opening 9 that is positioned on the eddy current segmenting device 8 of oil pocket 5 one sides is semicircular structure.The oil return filter screen 11 that is made of one with eddy current separating device 8 is installed on the steering oil outflow opening 9;
Like this, after steering oil flowed out from steering oil outflow opening 10, steering oil merger again flowed to out oil pocket 3 together, finally flows out from oil outlet 4.Foreign material in 11 pairs of steering oils of oil return filter screen play the effect of filtration.
The flow direction of steering oil greatly reduces the stirring degree of oil outlet part through twice change, make fuel-displaced steadily, bubble reduces.
The utility model is not limited to said structure, and the shape of steering oil outflow opening 9 on the eddy current segmenting device 8 and steering oil outflow opening 10 and the modification of number are all belonged to protection domain of the present utility model.
