Abstract
The utility model relates to a through bar vacuum booster belonging to a vacuum booster in the automobile brake system. The front casing components and the back casing components are riveted to ensure that the film sheet is firmly blocked and sealed, The seal ring components and the back casing components are riveted to ensure that they are fixed and sealed. Control valve components are riveted to ensure that they are connected and sealed, the film sheet and the valve body are riveted at rest by interference, the seal ring components and the valve body are sealed by interference and can slide, the two through bars are respectively sealed with the front casing under the compacting of an O-shaped seal ring , The bearing holder is fixed with the front casing, the two through bar are connected with the film sheet by interference and can slide, and then are riveted with the back casing components, the aided disc is riveted with the valve body. The advantages of the product are that it has a novel structure, its casing will not deform owing to bearing pressure during braking, its weight is light, which improves brake reliability, reduce the weight of the whole vehicle and can decrease traffic accidents.
Description
Technical field
The utility model relates to the vacuum booster of brake system of car technical field.
Background technology
The existing conventional vacuum booster that is used for automobile brake is to connect into an integral body by former and later two housings by the outer rim riveted way, comprises parts compositions such as front case, power-assisted dish, diaphragm, rear housing parts, sealing compact part spare, valve body, control cock parts, locking plate, reaction plate, master cylinder push rod, guard ring, pull back spring.Wherein front case is guaranteed the clamped fixing and extraneous sealing of diaphragm with the rear housing parts of rabbet in advance by riveted joint, fixing reaching and extraneous sealing guaranteed in seal ring parts and the riveted joint of rear housing parts, the riveted joint of control cock parts is guaranteed to connect and extraneous sealing, diaphragm and valve body are by the interference standstill seal, and seal ring parts and valve body are by the interference slipper seal.Valve rod, air valve seat that the brake weight of automobile driver is input to the control cock parts through stretcher etc. acts on briquetting, briquetting reach and the reaction plate realization assist function that works, the power output that increases passes to master brake cylinder by reaction plate, master cylinder push rod, sets up oil pressure and realizes braking function.
In order to guarantee Joint strenght and less distortion, generally, increase the material thickness of housing.Generally to reach the 1.5-1.8 millimeter.Because case material is thick to cause conventional vacuum booster weight big.It is yielding that housing transmits power, and it is slow to cause the braking idle travel to reach brake response greatly.Big specification: as 9 ", 10 ", 11 " the front and back housing of conventional vacuum booster riveted joint is easily thrown off, and diaphragm pulls from riveted joint easily, causes braking function to lose efficacy, and traffic accident very easily takes place, and seriously jeopardizes traffic safety.
Summary of the invention
The utility model provides a kind of rod-type vacuum booster that runs through, and is yielding to solve the housing transmission power that exists at present, causes the braking idle travel to reach the problem that brake response front and back housing slow, riveted joint easily throws off, makes braking function to lose efficacy greatly.The technical scheme that the utility model is taked is: front case 1 is connected diaphragm 4 clamp fittings by riveted joint with rear housing parts 6; Seal ring parts 10 and 6 riveted joints of rear housing parts; Air valve seat 13 and valve rod 8 riveted joints, rubber valve parts 9 covers are connected on the valve rod, reaction plate 15 is connected with valve body 12 interference, diaphragm 4 is connected with valve body 12 interference, seal ring parts 10 are connected with valve body 12 interference slipper seals, locking plate 11 is connected with 10 contacts of seal ring parts, briquetting 14 and valve body 12 sliding block joints, guard ring 16 is captiveed joint with valve body, master cylinder push rod 17 and valve body sliding block joint, return spring 18 is socketed in the outside of master cylinder push rod, two bars 7 respectively with front case 1 by O RunddichtringO 2 pinch-off seals, supporting seat 3 is captiveed joint with front case, two bars 7 respectively with diaphragm 4 interference sliding block joints, be connected power-assisted dish 5 and valve body 12 riveted joints with 6 riveted joints of rear housing parts.
Principle of work: the stretcher input force promotes the reaches such as valve rod 8, air valve seat 13 and rubber valve parts 9 of control cock parts during automobile brake, and rubber valve parts 9 contact and seal with valve body 12 and close valve vacuum valve port, and the chamber, front and back of vacuum booster is separated; The 13 continuation reaches of air valve seat separate with rubber valve parts 9 and open the atmosphere valve port, and air begins to enter true servo-unit back cavity and produces the power-assisted effect.Simultaneously air valve seat 13 acts on briquetting 14, and briquetting 14 produces follow-up actions with reaction plate 15 and realizes assist functions, and the power output of increase passes to master brake cylinder by reaction plate 15, master cylinder push rod 17, sets up oil pressure and realizes braking function; The power-assisted that treadle effort that chaufeur applies and vacuum produce passes to master cylinder by two bars, and housing does not transmit power before and after making.
The utility model advantage is: novel structure, there is not stress deformation at its housing of glancing impact, and improved the sensitieness of car load braking and the reliability of braking; In light weight, compare with the non-penetration type vacuum booster of routine and can alleviate about 30% weight, help reducing the automobile consumption of fuel, and can reduce since Vehicular vibration to the damage of product; Reduce material cost, only housing itself its material weight can reduce at double.Improved braking reliability, alleviated vehicle complete vehicle weight, can reduce the generation of traffic accident.
