Abstract
The utility model relates to a kind of control valve modular constructions for mitigating inflow noise, belong to automobile brake technical field.Valve rod and air valve base rivet, felt filter core, foam filter elements, valve rod spring abutment, valve rod return spring, rubber valve seat, rubber valve spring, rubber valve member are connected in series together, valve rod spring abutment, valve rod return spring, rubber valve seat, rubber valve member, rubber valve spring are fixed between air valve base and valve rod spring abutment by air valve base and valve rod by riveting.Utility model has the advantages that structure novel, only realized on original control valve member by increasing a floor clip and increasing limiting slot on valve rod, prevent the vibration between component, realize preferable noise reduction effect, compared with conventional control valve member, without too big increased costs, it further reduced intake efficiency, requirement suitable for different automobile types to inflow noise, better driving comfort sense is provided, blocking criteria design, can be applied on various types vacuum booster, while having good cost performance.
Description
Technical field
The utility model belongs to automobile brake technical field, refers in particular to control valve portion in a kind of vacuum booster assembly
Part, specifically a kind of control valve member for reducing inflow noise.
Background technique
The conventional control valve member in vacuum booster assembly is currently used in as shown in Figure 3, Figure 4 mainly by following part group
At: air valve base 1, valve rod 2, rubber valve seat component 3, rubber valve spring 4, rubber valve base 5, valve rod return spring 6, valve rod spring abutment 7,
Foam filter elements 8, felt filter core 9.In the frequent braking of automobile, there is opposite vibration in felt filter core and valve rod and valve body, make hair
Felt filter element and foam filter elements are deviate from from valve body, and intake efficiency is caused to increase, while causing the increase of inflow noise, influence vehicle
Subjective feeling, reduce the comfort of driver.
Summary of the invention
The utility model provides a kind of control valve modular construction for mitigating inflow noise, is filtered with solving felt in the prior art
There is opposite vibration between core and foam filter elements and valve rod and valve body, causes felt filter core and foam filter elements to be detached from from valve body, lead
It causes intake efficiency to increase, while causing the increase of inflow noise, influence the subjective feeling of vehicle, reduce the comfort of driver
Problem.
The technical solution of the utility model is: valve rod and air valve base rivet, by felt filter core, foam filter elements, valve rod spring
Seat, valve rod return spring, rubber valve seat, rubber valve spring, rubber valve member are connected in series together, and air valve base and valve rod will by riveting
Valve rod spring abutment, valve rod return spring, rubber valve seat, rubber valve member, rubber valve spring are fixed between air valve base and valve rod spring abutment；
There is limiting slot on the valve rod, floor clip is matched with limiting slot, while passing through floor clip and the valve rod upper limit
Felt filter core and foam filter elements are fixed between floor clip and valve rod spring abutment by the cooperation of position slot.
Utility model has the advantages that structure novel, only by increasing a floor clip on original control valve member
And increase limiting slot on valve rod and realize, it is therefore prevented that the vibration between component realizes preferable noise reduction effect, with conventional control
Valve member is compared, and without too big increased costs, be further reduced intake efficiency, is wanted suitable for different automobile types to inflow noise
It asks, better driving comfort sense is provided, blocking criteria design can be applied on various types vacuum booster, have simultaneously
Good cost performance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model valve rod；
Fig. 3 is the structural schematic diagram of the utility model background technique；
Fig. 4 is the structural schematic diagram of the utility model background technique valve rod；
In figure, air valve base 1, valve rod 2, rubber valve member 3, rubber valve spring 4, rubber valve seat 5, valve rod return spring 6, valve rod
Spring abutment 7, foam filter elements 8, felt filter core 9, floor clip 10, limiting slot 201.
Specific embodiment
Valve rod 2 and air valve base 1 rivet, by felt filter core 9, foam filter elements 8, valve rod spring abutment 7, valve rod return spring 6, rubber
Valve seat 5, rubber valve spring 4, rubber valve member 3 are connected in series together, and air valve base 1 and valve rod 2 are by riveting valve rod spring abutment 7, valve
Bar return spring 6, rubber valve seat 5, rubber valve member 3, rubber valve spring 4 are fixed between air valve base 1 and valve rod spring abutment 7；
There is limiting slot 201 on valve rod 2, floor clip 10 is matched with limiting slot 201, while passing through floor clip 10 and valve
Felt filter core 9 and foam filter elements 8 are fixed between floor clip 10 and valve rod spring abutment 7 by the cooperation of 2 upper limit position groove 201 of bar, group
At the control valve member of noise abatement.
The position for controlling valve stem spacing slot in valve member is determined according to the thickness of foam filter elements and felt filter core, is only controlled in original
Realize, without too big increased costs, not only have by increasing a floor clip and increasing limiting slot on valve rod on valve member processed
There is the function of conventional control valve member, also there is noise reduction function.
