Abstract
The utility model discloses an oiler diaphragm for an automobile brake master cylinder. The oiler diaphragm comprises a diaphragm body. The middle of the diaphragm body is recessed downwards, and the edges of diaphragm body warps upwards. The warped area of the diaphragm body is provided with annular corrugated ribs. The recessed area of the diaphragm body is provided with a cut. By the multi-layer corrugated ribs disposed at the top of the oiler diaphragm, seal effect is improved while seal reliability is improved, and airtightness and durability of the oiler diaphragm are improved. In addition, a cut is reserved in the middle of the oiler diaphragm, a vacuum lock is avoided during dropping of liquid level in a liquid storage tank while brake liquid is separated from the air, and accordingly moisture in the air is prevented from entering the brake liquid in the liquid storage tank.
Description
Technical field
The utility model relates to a kind of automobile braking master cylinder oil can diaphragm.
Background technology
The function of brake system is to make car deceleration or the parking of running at high speed, to guarantee that chaufeur and passenger escape injury, concrete braking procedure is: chaufeur impels push rod move to automobile braking master cylinder or leave automobile braking master cylinder by the motion of pedal, by various pipelines, pressure liquid is delivered to car side brake from automobile braking master cylinder, brakes or brake off.Automobile braking master cylinder is arranged on the dividing plate of engine room, mainly be made of fluid reservoir and Master cylinder body, wherein, fluid reservoir provides the braking liquid of master cylinder work, all fluid reservoirs have openable oil-can lid in order to add braking liquid, and the oil can diaphragm just is arranged on inside oil-can lid.The oil can diaphragm separates braking liquid and air, can freely move up and down with the variation of liquid level again, and the oil can diaphragm can prevent that airborne moisture from entering into the braking liquid of fluid reservoir.Yet present oil can diaphragm seal poor effect, and the vacuum lock that easily forms when falling of fluid reservoir liquid level affects the proper flow of braking liquid, can't reach the effect of good braking, demand improvement urgently.
The utility model content
Problem for the prior art existence, the purpose of this utility model is to propose a kind of automobile braking master cylinder oil can diaphragm, by enforcement of the present utility model, effectively improve braking oilcan internal pressure, ventilation environment, improve sealing characteristics and the movement sensitive of vacuum booster, improve simultaneously leak tightness and the endurance quality of oil can diaphragm itself.
For reaching this purpose, the utility model by the following technical solutions:
A kind of automobile braking master cylinder oil can diaphragm comprises:
The diaphragm body, in the middle of described diaphragm body, to recessed, periphery is upturned;
The zone that described diaphragm body periphery is upturned is provided with the annular ripple muscle;
Be provided with otch to recessed zone in the middle of described diaphragm body.
Preferably, the cross section of described ripple muscle is triangle or waveform.
Preferably, described triangle drift angle is the 60-90 degree, and the summit is 0.8 to 1.0 millimeter to the base height.
Preferably, described annular ripple muscle is 3 to 5 circles.
Preferably, described otch is positioned at described recessed area midway location.
Preferably, described otch is the breach of 3 to 5 millimeters long.
Preferably, described oil can diaphragm material is ethylene-propylene diene copolymer.
Based on disclosing of above technical scheme, the utility model possesses following beneficial effect:
The utility model has strengthened sealing effectiveness by oil can diaphragm top multilayer corrugated shape sealed muscle, can improve the reliability of sealing again simultaneously, and improves leak tightness and the endurance quality of oil can diaphragm itself.In addition, take otch in the middle of the oil can diaphragm, prevent from forming vacuum lock when the fluid reservoir liquid level from falling, simultaneously braking liquid and air are separated, prevent that airborne moisture from entering into the braking liquid of fluid reservoir.
Description of drawings
Fig. 1 is the structural representation that a kind of automobile braking master cylinder of the utility model embodiment 1 is used the oil can diaphragm;
Fig. 2 is the assembly drowing that a kind of automobile braking master cylinder of the utility model embodiment 1 is used the oil can diaphragm.
Reference numeral:
1, ripple muscle; 2, otch.
The specific embodiment
The utility model embodiment 1 provides a kind of automobile braking master cylinder oil can diaphragm, as depicted in figs. 1 and 2, comprising: the diaphragm body, and in the middle of described diaphragm body, to recessed, periphery is upturned; The zone that described diaphragm body periphery is upturned is provided with annular ripple muscle 1, and the cross section of described ripple muscle can be triangle, waveform or other shape, adopts 3-5 circle ripple muscle sealing effectiveness better.Be provided with otch 2 to recessed zone in the middle of described diaphragm body, energy actv. release of pressure and vacuum venting, when the diaphragm installation was smooth, otch sealed, and reaches the pressure in effective adjusting oil can tank.
When ripple muscle 1 enclosed the triangle ripple muscle of projection for 3-5, drift angle was the 60-90 degree, and the summit is 0.8-1.0mm to the degree of depth on base.By protruding triangle ripple muscle, contact surface changes the contact of 3-5 circle ripple muscle into by original plane contact, though that area of contact reduces the power of contact is larger and the contact of 3-5 layer arranged, sealing effectiveness is better, seal more guaranteed, the sealing property of raising fluid reservoir diaphragm.
Diaphragm material selects the ethylene-propylene diene copolymer of high-low temperature resistant (40 ℃～150 ℃) and resistance to braking fluid to make, and adopts the mould compression molding of turnover panel.Produce the oil can diaphragm and adopt the mold pressing production technology, adopt profiled member feeder material loading to shorten the non-cutting time of material loading for enhancing productivity, thereby guarantee the relative stability of curing temperature, thereby guarantee the stability of oil can diaphragm size and performance, improve production qualification rate and efficient; Oil can diaphragm cylindrical sealing place effect is subjected to the impact (matched moulds size) of overlap size in addition, by design torn edges groove and clout groove, make flowing fully of sizing material, guarantee that the height of overlap and gauge are qualified, greatly improved movement sensitive performance and the endurance quality of product.Considered the maintenance of torn edges groove and clout groove, consider that simultaneously top corrugated sealing ring processing request is smooth, machinability and intensity to mold materials on Design of Dies propose higher requirement, by the contrast of physical and mechanical properties and machinability, select the SM1 steel; Board selection 718 steel.
The above; it is only the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or changed according to the technical solution of the utility model and utility model design thereof, within all should being encompassed in protection domain of the present utility model.
