Description
Technical field
The present invention relates to automobile steering system, be specifically related to a kind of liquid level controllable type power steering oil reservoir.
Background technology
Existing power steering oil reservoir comprises tank body, cover, filter core, oil scale, cover. Cover or oil scale are provided with passage. Power steering oil reservoir is non-pressure vessel in work, and it is unimpeded that passage must ensure, to ensure that the pressure in power steering oil reservoir does not cause the pressure in power steering oil reservoir to change with level change in the automobile steering system course of work. Because vehicle is in the variation of the jolting of running, slope change and the cold and hot large volume of fluid, for preventing passage leakage of oil, in Oil Tank Design and use procedure, require in oil tank at least reserved 1/3 expansion space. Although oil tank is provided with oil scale, but two lines are just simply carved, user is in use difficult to judge accurately oil level, it is always quite a lot of that while general user thinks that oil tank fills some oil more, cause an always full tank oil of oil tank in time use procedure, cannot stay 1/3 expansion space at all. In use a large amount of oil overflows from passage, on passage and cover, form one deck oil film, be combined with airborne dust and form gradually the greasy filth of thick layer, both affected the outward appearance while of power steering oil reservoir along with the prolongation of time, greasy filth on passage is cumulative stops up passage, cause in the steering course of work oil circulation not smooth, direction is heavy and unstable, when serious, can cause steering failure.
Summary of the invention
The technical problem to be solved in the present invention is, for existing power steering oil reservoir above shortcomings, a kind of liquid level controllable type power steering oil reservoir is provided, it can effectively control the liquid level in oil tank, even if user fills it up with 2/3 the fluid of also can only annotating, guarantee to reserve 1/3 expansion space, avoid passage oil spilling; Improve the security of the steering course of work.
