The present invention relates to the vacuum boosters of a kind of pair of input power push rod limit, it is characterized by: pedal attachment device is connect with control valve member, control valve member is connect with valve body, valve body is connect with input power push rod, and input power push rod and limiting device front aperture are socketed, and input power push rod and limiting device are interference fitted, piston is connect with Master cylinder body, input power push rod one end is located in piston, and the support of limiting device outer circle is connect with valve body, and return spring is between limiting device and front housing contact level.The present invention has the advantages that structure novel, assembling is good, the splitted structure and input power push rod of the front aperture of limiting device cooperate gapless, reduce because the incidence of the Master cylinder body damaged due to being biased to movement occurs for gap, guiding performance improves simultaneously, the generation for reducing abnormal sound, improves driver comfort.

Description

A kind of vacuum booster of pair of input power push rod limit
Technical field
The invention belongs to automobile brake technical fields, are applied to brake system of car, refer in particular to automobile vacuum booster Middle input power push rod limiting device.
Background technique
Vacuum booster is the brake power assist unit in brake system of car, is vapour for assisting driver to brake Critical component in vehicle braking system.
The working principle of vacuum booster sucks air when being using engine operation, causes the side vacuum of booster, Pressure relative to other side normal air generates pressure difference, brake force is generated using pressure difference, to realize the mesh of braking 's.When the braking of driver's brake pedal, pedal force pushes input power push rod to master cylinder applied force together with control device, from And master cylinder is made to generate centainly hydraulic.When pedal force pushes input power push rod that input power is transmitted to master by control device When cylinder, the device of position-limiting action is housed on the outside of input power push rod, the return spring for being fixedly supported on procapsid and valve body, And there are gaps between this limiting device and input power push rod, easily occur to be biased to friction and abnormal sound problem in transmission force, to true Empty booster assembly seriously affects, or even power-assisted can be made to fail, brake failure, generates and seriously threatens to the safety of driver, because This, the limiting device of input power push rod is very crucial part.
Traditional vacuum booster limiting device is that input power push rod is passed through to recoil on valve body, limiting device and input Pushing bar is clearance fit.With pedal force input drive control device push input power push rod, due to input power push rod with Limiting device is clearance fit, and input power push rod is easily amesiality during the motion, when touching inside Master cylinder body, is biased to fortune It moves and causes Master cylinder body casing wall wear phenomenon, it is this to wear the problems such as scratch formed damage leather cup, cause brake fade.
Summary of the invention
The present invention provides the vacuum booster of a kind of pair of input power push rod limit, to solve the work of vacuum booster assembly In, input power push rod leads to the problem of Master cylinder body eccentric wear and abnormal sound due to limiting improper.
The technical scheme is that pedal attachment device is connect with control valve member, control valve member is connect with valve body, Valve body is connect with input power push rod, and input power push rod and limiting device front aperture are socketed, input power push rod and limiting device interference Cooperation, piston are connect with Master cylinder body, and input power push rod one end is located in piston, and the support of limiting device outer circle is connect with valve body, are returned Position spring is between limiting device and front housing contact level.
The limiting device is elastomeric material, constrained devices front aperture on limiting device, the support of limiting device outer circle, Split-type structure, split-type structure are located above limit device front aperture；The return spring is metal material；The control valve Component is rubber and metallic combination material；The pedal attachment device is metal material.
The present invention has the advantages that structure novel, assembling is good, the splitted structure and input power of the front aperture of limiting device Push rod cooperates gapless, reduces the incidence of the Master cylinder body damaged because deviation movement occurs for gap, while guiding performance improves, The generation for reducing abnormal sound, improves driver comfort.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the positional diagram of input power push rod and limiting device of the present invention；
Fig. 3 is the cross-sectional view of limiting device of the present invention；
Fig. 4 is the A direction view of Fig. 3；
In figure, pedal attachment device 1, control valve member 2, valve body 3, limiting device 4, input power push rod 5, return spring 6, Master cylinder body 7, piston 8, front housing contact level 9, limit device front aperture 401, limiting device outer circle support 402, split-type structure 403.
Specific embodiment
Pedal attachment device 1 is connect with control valve member 2, and control valve member 2 is connect with valve body 3, and valve body 3 is pushed with input Bar 5 connects, and input power push rod 5 and limiting device front aperture 401 are socketed, and input power push rod 5 and limiting device 4 are interference fitted, living Plug 8 is connect with Master cylinder body 7, and 5 one end of input power push rod is located in piston 8, and limiting device outer circle support 402 is connect with valve body 3, is returned Position spring 6 is between limiting device 4 and front housing contact level 9.
Limiting device 4 is elastomeric material, constrained devices front aperture 401, the support of limiting device outer circle on limiting device 4 402, split-type structure 403, split-type structure 403 are located above limit device front aperture 401；Return spring 6 is metal material；Control Valve member 2 is rubber and metallic combination material；Pedal attachment device 1 is metal material.
External force is transmitted to control valve member by pedal attachment device when movement, then power is transmitted to input power by valve body Push rod, when input power pushrod movement, are oriented to by limiting device, guarantee that the output of power does not damage Master cylinder body, limiting device plays limit The effect of guiding.
When assembly, after pedal attachment device is connect with control valve member, fixed after being packed into valve body, valve body connects with chamber part is divided Rear forming member is connect, limiting device front aperture is inserted in from input power push rod front end, and limiting device is elastic component, and input power push rod is Metalwork.Split-type structure in limiting device front aperture is generated deformation by the active force of input power push rod, and valve is divided to open, after The continuous active force applied to limiting device to the right, divides valve to be closed, and the support of limiting device outer circle is made to be tightly placed in the outer of input power push rod On nose circle face.
When work, external force pushes control valve member to be moved to the left by pedal attachment device, and valve body is together with its portion Part moves downward simultaneously, and since return spring acts on limiting device, power is input on limiting device and input power push rod at this time, They overcome the active force of return spring, are moved to the left, in input power pushrod movement to Master cylinder body, in the limit of limiting device Under effect, input power push rod keeps horizontal and promotes, and does not damage and scratches piston inner hole wall, therefore guarantees that Master cylinder body inner wall is not drawn Hurt phenomenon.
