Abstract
The utility model discloses a ventilation device for an automobile electric power steering system, which comprises a ventilation plug body, a cover, a breathable film and a sealing ring. The breathable film is arranged between the ventilation plug body and the cover; and the sealing ring is arranged at the joint of the ventilation plug body and a steering gear shell. By arranging the ventilation device on an electric steering gear enclosure, air exchange inside and outside the enclosure is realized, and the ventilation device takes an effect of balancing air inside and outside the enclosure; and meanwhile, the arranged breathable film is a semipermeable film and chemical solution such as water, engine oil, gasoline and the like are kept out of the breathable film, so that safety of the system is ensured.
Description
Technical field
The utility model relates to a kind of automobile electric booster steering system seal fitting, and specifically, what relate to is a kind of automobile electric booster steering system gas permeable devices.
Background technology
Automobile electric booster steering system (EPS) is the developing direction of automobile steering system.This system directly provides power steering by electric boosted machine, has saved the necessary power steering oil pump of hydraulic power steering system, flexible pipe, hydraulic oil, belt conveyor and has been loaded on belt pulley on the driving engine, has both saved energy, has protected environment again.In addition, also have the characteristics that adjustment is simple, assembling is flexible and power steering can both be provided under multiple situation.
Electric booster steering device adopts the design of integral sealing formula, and the bellows-type sealing structure is adopted at two ends.The shortcoming of this structure is that rapid expansion can take place gas when deflector internal temperature acute variation, and the gas of expansion can make the distortion of deflector two ends bellowss, causes noise, fatigue wear, thereby causes problem such as system's leakage.
The utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, a kind of automobile electric booster steering system gas permeable devices is provided, casing at electric direction varying device arranges gas permeable devices, can realize the air inerchange that casing is inside and outside, thereby effectively solve bellows distortion and the problems such as the noise that causes, fatigue wear thereof that connect deflector.
For realizing above-mentioned purpose, a kind of automobile electric booster steering system gas permeable devices described in the utility model, comprise porous plug body, lid, ventilated membrane and seal ring, be provided with described ventilated membrane between described porous plug body and the described lid, described porous plug body and steering gear housing junction are provided with described seal ring.
The part that described porous plug body connects steering gear housing is trapezoidal, and its upper diameter is greater than the middle part diameter, and is provided with bulge-structure on top.
Described porous plug body is hollow structure.
The hollow part of described porous plug body connects described ventilated membrane.
Described ventilated membrane is pellicle.
Described lid is provided with a plurality of air gates.
Described seal ring is the O RunddichtringO.
In the utility model, described porous plug body is provided with bulge-structure, be connected with the ventilative consent of the casing of electric direction varying device tightr, difficult drop-off; When the casing of electric direction varying device is installed described porous plug body, described O RunddichtringO is set and plays sealing function, guarantee the leak tightness of total system; When deflector internal temperature acute variation causes gas to take place sharply to expand, sharply the gas that expands is discharged through the air gate that described ventilated membrane enters described stopper from the hollow part of described porous plug body, realized the air inerchange of steering housing inside and outside, can not cause connecting the deflector two ends the bellows distortion, make a noise and fatigue wear causes the problem of system leak; Simultaneously described ventilated membrane adopts semipermeable membrane material, does not allow chemical solutions such as water, machine oil, gasoline to enter deflector, has ensured the safety of deflector.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with drawings and Examples the technical solution of the utility model is further explained, but following content is not used in restriction protection domain of the present utility model.
As shown in Figure 1, present embodiment provides a kind of automobile electric booster steering system gas permeable devices, comprise porous plug body 1, lid 2, ventilated membrane 3 and O RunddichtringO 4, be provided with described ventilated membrane 3 between described porous plug body 1 and the described lid 2, described porous plug body 1 is provided with described O RunddichtringO 4 with the steering gear housing junction.
The part that described porous plug body 1 connects steering gear housing is trapezoidal, and its upper diameter is greater than the middle part diameter, and is provided with bulge-structure 5 on top.
Described porous plug body 1 is hollow structure.
The hollow part of described porous plug body 1 connects described ventilated membrane 3.
Described ventilated membrane 3 adopts semipermeable membrane material.
Described lid 2 is provided with a plurality of air gates.
Described porous plug body 1 is provided with bulge-structure 5, be connected with the ventilative consent of the casing of electric direction varying device tightr, difficult drop-off; When the casing of electric direction varying device is installed described porous plug body 1, described O RunddichtringO 4 is set and plays sealing function, guarantee the leak tightness of total system; When deflector internal temperature acute variation causes gas to take place sharply to expand, sharply the gas that expands is discharged through the air gate that described ventilated membrane 3 enters described stopper 2 from the hollow part of described porous plug body 1, realized the air inerchange of steering housing inside and outside, can not cause connecting the deflector two ends the bellows distortion, make a noise and fatigue wear causes the problem of system leak; Simultaneously described ventilated membrane 3 adopts semipermeable membrane material, does not allow chemical solutions such as water, machine oil, gasoline to enter deflector, has ensured the safety of deflector.The utility model is simple in structure, and is convenient and practical.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute all will be apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
