Description
Technical field
The utility model belongs to a kind of automotive brake, more particularly to a kind of procapsid assembly of automobile vacuum booster.
Background technology
The effect of brake system in the car is particularly significant, can ensure the traffic safety of people, and the weight of brake system
It is vacuum booster to want part, and its principle is using vacuum caused by automobile engine or vavuum pump, by a housing
Two different operating chamber epitheliums between pressure differential change, come play a part of increase master cylinder thrust.Booster
A back-moving spring is internally provided with, for that will reset booster, funnel shaped can be used in some larger boosters
Back-moving spring, to ensure that reset force is uniform, but spring influences to reset accuracy using easily deforming afterwards long.
The content of the invention
In view of the deficienciess of the prior art, the utility model provides a kind of simple in construction, service-strong vacuum automobile
The procapsid assembly of booster.
The technical scheme that the utility model is taken to achieve the above object is：
A kind of procapsid assembly of automobile vacuum booster, the assembly include procapsid, by setting on described procapsid
Put plinth with inlet suction port to be connected, mounting screw is set on described procapsid, between described mounting screw and procapsid
Reinforcing plate is set.
As a further improvement, the screw cap end of described mounting screw sets the peace of groove, described groove and procapsid
Groove is engaged in dress hole.
As a further improvement, multiple declining lugs are set on the nut medial surface of described mounting screw.
The utility model is simple in construction, using it is reliable the features such as.By add reinforcing plate and modification bolt structure make its
Due to the effect of mechanical pressure, projection insertion reinforcing plate, groove part and fore shell body phase while riveted procapsid and reinforcing plate
It is ratcheting.
