Abstract
The utility model provides an exhaust structure of vehicle dynamic steering oilcan belongs to car technical field. It has solved how to reduce oil gas exhaust problem. This power steering oilcan includes inner cup body and the cylindrical dipstick pole portion that is that lies in inner cup body bottom, and this internally has an oil storage chamber inner cup, and this exhaust structure is formed with the annular groove including lieing in the annular buffer substrate tablet in the dipstick pole portion between annular buffer substrate tablet and the inner cup body, the bottom of annular groove be provided with with the oil storage communicating exhaust hole in chamber. Originally, the exhaust structure who turns to the oilcan through the improvement of above structure, has changed the exhaust route through setting up annular buffer substrate tablet, changing the position in exhaust hole and set up the dashpot, improves oil -gas separation's dynamics to reduce the discharge of oil gas, reduced the greasy dirt on power steering oilcan assembly surface.
Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of power steering oil pot of automobile, particularly a kind of exhaust structure of power steering oil pot of automobile.
Background technique
Turning to oil storage kettle in hydraulic booster vehicle steering system, is the container that hydraulic steering system stores fluid.Simultaneously after automobile running, high-temperature gas to be discharged by servosteering oil can assembly in hydraulic steering system, protect reliability, the Security of hydraulic steering system with this.Its structure is primarily of formations such as pot lid, housing, filter screens.
As Chinese Patent Application No.: 200920188226.3, Authorization Notice No.: CN201545055U discloses a kind of servosteering oil can, include kettle body, pot lid, described kettle body is by upper, lower kettle body is linked together by Vibration welding, described upper kettle body oral area is provided with ring bush, upper kettle body oral area is provided with pot lid, sealing gasket is provided with between described pot lid and upper kettle body oral area, described lower kettle body is provided with oil inlet pipe interface and oil outlet tube interface, filter screen is provided with in described lower kettle body, described lower kettle body is provided with the directional post of mistake proofing, described lining is provided with exhaust structure, described kettle extracorporeal set has sheath, described kettle body and pot lid material are for strengthen nylon.
The irrationality that above-mentioned servosteering oil can designs due to exhaust structure, sealing gasket is without buffering, radiating structure coupling, oil gas is caused easily to occur leakage of oil or oil impregnate phenomenon from the seam crossing of pot lid and kettle body, thus the greasy dirt causing servosteering assembly surface contamination one deck thick.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of exhaust structure of power steering oil pot of automobile, and the technical problem that the utility model solves how to reduce oil gas to discharge.
The purpose of this utility model realizes by following technical proposal: a kind of exhaust structure of power steering oil pot of automobile, described servosteering oil can comprises inner cap body and is positioned at the oil rule rod portion in column of described inner cap body bottom portion, in described inner cap body, there is shoe cream room, it is characterized in that, described exhaust structure comprises the loop buffer sheet be positioned in oil rule rod portion, be formed with annular groove between described loop buffer sheet and inner cap body, the bottom of described annular groove is provided with the exhaust port communicated with shoe cream room.
The exhaust structure of this power steering oil pot of automobile passes through in the interior bottom covering the annular groove setting up loop buffer sheet and exhaust port is arranged on loop buffer sheet and the formation of inner cap body bottom portion, change the path of exhaust of oil thus, first annular groove will be entered during exhaust of oil, enter exhaust port again, increase exhaust pathway, be conducive to Oil-gas Separation; Meanwhile, when fluid intense vibration, loop buffer sheet can effectively stop fluid to enter to be positioned at inner exhaust port, thus reduces oil gas and ooze out oil can pot lid surface through exhaust port, and then reduces the greasy dirt on oil can assembly surface.
In the exhaust structure of above-mentioned power steering oil pot of automobile, the aperture of described exhaust port is positioned at the lowest part of described shoe cream room.Exhaust port and inlet hole function can be exchanged, once fluid enters, also can be stored in shoe cream room, because fluid stores height higher than exhaust port, can be back in oil can kettle body when not being vented, and are conducive to the greasy dirt reducing oil can assembly surface.
In the exhaust structure of above-mentioned power steering oil pot of automobile, the bottom of described shoe cream room has the boss raised up, and the height of described boss is higher than the height in exhaust port aperture.When oil gas enters shoe cream room through exhaust port, boss can make part Oil-gas Separation, thus reduces oil gas discharge.
In the exhaust structure of above-mentioned power steering oil pot of automobile, described boss is small end circular cone upward.Boss is designed to circular cone, makes to bring about the desired sensation along conical surface up to walk, and the fluid separated is toward dirty, improves oil-gas separation efficiency, thus reduces oil gas discharge.
In the exhaust structure of above-mentioned power steering oil pot of automobile, the upper surface of described inner cap body is provided with the ringwise dashpot of multiple tracks.Gas is cushioned by dashpot after being discharged by exhaust port, makes part Oil-gas Separation, thus reduces oil gas discharge.
Compared with prior art, the exhaust structure of this power steering oil pot of automobile has the following advantages: originally turn to the exhaust structure of oil can by arranging loop buffer sheet, changing the position of exhaust port and arrange dashpot, by the improvement of above structure, change exhaust pathway, improve the dynamics of Oil-gas Separation, thus decrease the discharge of oil gas, decrease the greasy dirt on servosteering oil can assembly surface.
