Abstract
The utility model is related to vacuum booster technical field more particularly to a kind of feedback component, including reaction plate（1）, the pressure input that offsets in the middle part of one end and reaction plate fills in（2）, be set in pressure input beyond the Great Wall and with the feedback tray that offsets of feedback plate edge（3）And for entangling reaction plate and feeding back the closing set of tray（4）, the reaction plate（1）With feeding back tray（3）Between be filled with pressure-air.This feedback component reset effect is preferable.
Description
Technical field
The utility model is related to vacuum booster technical field more particularly to a kind of feedback components.
Background technology
Feedback component is the important component of vacuum booster, it includes offseting in the middle part of reaction plate, one end and reaction plate
And the feedback undertaking that the pressure input that the other end and push rod offset fills in, is set in pressure input beyond the Great Wall and offsets with feedback plate edge
Disk and the closing set for entangling reaction plate and feedback tray, but prior art reaction plate relies primarily on its own resilient
It resets, such reset effect is poor.
The content of the invention
Technical problem to be solved in the utility model is：There is provided a kind of reset effect preferable feedback component.
Technical solution is used by the utility model：A kind of feedback component, in the middle part of reaction plate, one end and reaction plate
The pressure to offset inputs plug, the feedback tray for being set in pressure input beyond the Great Wall and offseting with feedback plate edge and for entangling
Reaction plate and the closing set for feeding back tray are filled with pressure-air between reaction plate and feedback tray.
Using more than structure compared with prior art, the utility model has the following advantages：It is accepted in reaction plate and feedback
Pressure-air is filled between disk, can so play the role of the pressure of Rapid reset to reaction plate.
Preferably, reaction plate is equipped with the resetting-mechanism that reaction plate is helped to reset.One resetting-mechanism is set, so may be used
So that the reset that reaction plate energy is good.
Preferably, resetting-mechanism sieves for honeycomb.Resetting-mechanism is used as using honeycomb sieve, reset effect is preferable.
Preferably, reaction plate contacts one end as spherical surface with pressure input plug, and reaction plate is triangle.Reaction plate one end
It is arranged to spherical surface, is so easier to be deformed, and reaction plate whole installation is so also easier to squeeze change into triangle
Shape.
Description of the drawings
Fig. 1 is the sectional view of the utility model feedback component.
Fig. 2 is the structure diagram of reaction plate and resetting-mechanism in the utility model feedback component.
As shown in the figure：1st, reaction plate；2nd, pressure input plug；3rd, tray is fed back；4th, closing set；5th, resetting-mechanism.
Specific embodiment
The utility model is described further with specific embodiment below in conjunction with attached drawing, but the utility model is not only
It is limited to detailed description below.
A kind of feedback component, the pressure input including offseting in the middle part of reaction plate 1, one end and reaction plate fill in 2, are set in pressure
The feedback tray 3 that input offsets beyond the Great Wall and with feedback plate edge and the closing for entangling reaction plate and feedback tray
Set 4 is filled with pressure-air between reaction plate 1 and feedback tray 3.
Reaction plate is equipped with the resetting-mechanism 5 that reaction plate is helped to reset.
Resetting-mechanism 5 sieves for honeycomb.
Reaction plate 1 contacts one end as spherical surface with pressure input plug 2, and reaction plate 1 is triangle.
Certainly, the aid illustration as present case, to improve 1 spring characteristic of reaction plate or improving the friction longevity of reaction plate 1
Life can add resistance to compression lubricating grease or lubrication between the push rod and two contact surfaces of feedback tray 3 being in contact with reaction plate 1
Oil, it is also possible to which the contact surface of graphite medium or push rod and feedback tray 3 is plasticized or the kinds of processes side such as saponification process
Case.
