Abstract
The invention relates to an automobile brake oil storage kettle opening cover assembly, which comprises an oil storage kettle opening part and an oil storage kettle cover arranged at the oil storage kettle opening part, wherein a sealing pad is arranged between the oil storage kettle opening part and the oil storage kettle cover, the sealing pad is downwards recessed for forming a bowl-shaped oil storage cavity, a ventilation hole is formed in the center position of the bottom of the sealing pad, an oil blocking pipe is arranged under the sealing pad, and the upper end of the oil blocking pipe is communicated with the ventilation hole. The automobile brake oil storage kettle opening cover assembly has the characteristics that the ventilation performance requirement of an oil storage kettle can be met, braking fluid can be prevented from leaking to the surface of the oil storage kettle, the structure is simple, the manufacturing is easy, and the cost is low.
Description
Technical field
The present invention relates to auto brake system parts, be specifically related to a kind of automobile brake oil storage kettle lid assembly.
Background technology
Automobile brake oil storage kettle is generally arranged on master brake cylinder, braking liquid is provided directly to master brake cylinder, and the effect of oil storage kettle lid packing seal is tight storage kettle, prevent braking liquid from revealing, the aeration that will ensure oil storage kettle is paid somebody's debt and expected repayment later in sealing simultaneously, when the supplementary braking liquid of needs, can not produce because oil storage kettle internal pressure unanimously causes braking liquid to decline and supplementary risk can not be completed in time.As shown in Figure 1, packing seal in traditional oil storage kettle lid assembly is planar configuration, interference fit is adopted between packing seal and oil storage kettle, free-running fit is adopted between packing seal and oil storage kettle lid, the middle part of packing seal is provided with air extractor vent, communicated with air by this air extractor vent, there is following drawback in this structure: at automobile bumpiness or when being traveling in descending road surface, braking liquid is caused to ripple in oil storage kettle owing to braking the shake of oil storage kettle or inclination, braking liquid can flow out to the external world through packing seal air extractor vent, after vehicle uses a period of time, oil storage kettle surface is residual a little braking liquid often, easily cause the complaint of user.
And for example CN103786712A disclosed " a kind of automobile brake oil storage kettle lid assembly ", this braking oil storage kettle lid assembly, comprise oil storage pot lid, it is characterized in that: also comprise a vent valve seat, be located at the supermedial seal ring of described vent valve seat, the middle part of described vent valve seat and bottom to be stretched in oil storage kettle and are coordinated with its mouth inner wall; The upper end rotary clamping of described oil storage pot lid and vent valve seat, and have a little up and down amount, it can not only meet the requirement of oil storage kettle aeration, can also prevent braking liquid from revealing or being taken to oil storage kettle surface by gas.But the version that the employing seal ring of this braking oil storage kettle lid assembly coordinates with vent valve seat is comparatively complicated, the Special ventilating valve seat be especially provided with, this vent valve seat is complex structure, manufacture difficulty not only, and cost intensive.
Summary of the invention
The object of the present invention is to provide a kind of automobile brake oil storage kettle lid assembly, it can meet the aeration requirement of oil storage kettle, and braking liquid can be prevented to be leaked to oil storage kettle surface, and has structure feature simple, easy to manufacture and with low cost.
Automobile brake oil storage kettle lid assembly of the present invention, comprise oil storage kettle oral area and be located at the oil storage pot lid of oil storage kettle oral area, packing seal is provided with between oil storage kettle oral area and oil storage pot lid, the shoe cream room that the recessed formation of sealing pad is bowl-shape, air extractor vent is provided with at the bottom center of packing seal, below described packing seal, be provided with gear oil pipe, the upper end of this gear oil pipe communicates with described air extractor vent.
Further, described gear oil pipe and packing seal are an entirety.
Because oil storage kettle inside is by gear oil pipe, air extractor vent and shoe cream room and communicate with ambient atmosphere, at automobile bumpiness or when being traveling in descending road surface, braking liquid ripples in process in oil storage kettle, part braking liquid is kept off oil pipe surface gear and is back in oil storage kettle, part braking liquid can through gear oil pipe, air extractor vent flow in bowl-shape shoe cream room, this bowl-shape shoe cream room has a constant volume, braking liquid is made to store in shoe cream room and the external world can not be flow into, under certain condition (as running car is smooth-going), braking liquid in shoe cream room can be back in oil storage kettle through air extractor vent.
The present invention has the following advantages: at automobile bumpiness or when being traveling in descending road surface and causing braking liquid to ripple in oil storage kettle, the braking liquid flowed out by air extractor vent is stored by shoe cream room bowl-shape on packing seal, make braking liquid to flow into the external world, prevent braking liquid to be leaked to oil storage kettle surface.The present invention has structure advantage simple, easy to manufacture and with low cost.
Accompanying drawing explanation
Fig. 1 is the section-drawing of existing braking oil storage lid assembly;
Fig. 2 is section-drawing of the present invention;
Fig. 3 is the section-drawing of packing seal.
In figure: 1-oil storage kettle oral area, 2-packing seal, 21-shoe cream room, 22-air extractor vent, 23-keeps off oil pipe, 3-oil storage pot lid.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 2 and Figure 3, described automobile brake oil storage kettle lid assembly, comprise oil storage kettle oral area 1 and be located at the oil storage pot lid 3 of oil storage kettle oral area, packing seal 2 is provided with between oil storage kettle oral area 1 and oil storage pot lid 3, the shoe cream room 21 that the recessed formation of sealing pad 2 is bowl-shape, is provided with air extractor vent 22 at the bottom center of packing seal 2, is provided with gear oil pipe 23 below described packing seal 2, described gear oil pipe 23 and packing seal 2 are an entirety, and the upper end of this gear oil pipe communicates with described air extractor vent.
Because oil storage kettle inside is by gear oil pipe, air extractor vent and shoe cream room and communicate with ambient atmosphere, at automobile bumpiness or when being traveling in descending road surface, braking liquid ripples in process in oil storage kettle, part braking liquid is kept off oil pipe surface gear and is back in oil storage kettle, part braking liquid can through gear oil pipe, air extractor vent flow in bowl-shape shoe cream room, flow in bowl-shape shoe cream room (this process is see the direction of arrow in Fig. 2), this bowl-shape shoe cream room has a constant volume, braking liquid is made to store in shoe cream room and the external world can not be flow into, as smooth-going in running car under certain condition, braking liquid in shoe cream room can through air extractor vent, gear oil pipe is back in oil storage kettle (this process is see arrow opposite sense in Fig. 2).
