Description
Technical field
The invention belongs to brake system of car technical fields, refer in particular to a kind of vacuum booster assembly.
Background technique
The conventional vacuum booster assembly of automobile brake is currently used for by procapsid, back casing, bolt of rear case, rear shell
Sealing gland, control valve member, locking plate, dust cover, adjustment fork, briquetting, reaction plate, master cylinder push rod, guard ring, return spring, valve body, film
The main parts sizes such as piece, boosting disk composition.
In the work of conventional vacuum booster assembly, by brake pedal input force, drives control valve member and valve body to cooperate, lead to
It crosses diaphragm and vacuum booster assembly is divided into two chamber of front and back, ante-chamber is vacuum chamber, and back cavity is connected atmosphere, produced by atmospheric pressure effect
Raw power-assisted effect.
But with electric car industrial development, small-sized electric vehicle gradually enters into daily life, to small size vacuum servo
Device demand is consequently increased.Traditional 8 inch vacuum booster diaphragm assembly methods be between diaphragm and valve body using magnitude of interference compared with
Big mode is assembled, and tooling auxiliary tool is needed to be assisted, more demanding to operator in assembly, such as cannot fit into position, can
Product power-assisted can be caused to fail, running car is caused the friendship such as easily to knock into the back, collide on crowded city and highway
Interpreter's event, the safety of serious threat to life property.
Summary of the invention
The present invention provides a kind of 8 inch vacuum booster assemblies with floating type diaphragm structure, to solve due to diaphragm
With valve body assembly it is not in place caused by vacuum booster fail the problem of.
The technical scheme is that procapsid component and back casing component rivet, diaphragm be mounted on procapsid component and
Between back casing component, rear shell sealing gland and back casing component are interference fitted, and form sealing shell, and rear shell sealing gland is matched with valve body interference
It closes, boosting disk and valve body rivet, and control valve member and valve body are clamped by locking plate and are assembled, reaction plate, guard ring, master cylinder push rod assembly
In valve inner, return spring is assemblied on guard ring, and dust cover is assemblied on back casing component.
There are floating sealing structure, clamping location structure on the diaphragm, valve body is connect by floating sealing structure with diaphragm,
There are one L1 of seal band and seal band two L2, L1 47.4mm, L2 49.3mm on floating sealing structure, boosting disk passes through card
Location structure is connect to connect with diaphragm.
The present invention has the advantages that structure novel, improves diaphragm and boosting disk and valve body contact position locating, increase
Diaphragm and valve body locating piece become original diaphragm and valve body interference fit into floating structure, to avoid because due to diaphragm and valve body
Assemble it is not in place caused by vacuum booster failure, improve product reliability, very good solution traditional structure diaphragm with
Valve body fit structure easily occurs assembling disadvantage not in place on 8 inches of products, and has well-located, and assembly is simple, accounts for
It is small with space, it is easy to process.

Specific embodiment
Procapsid component 1 and back casing component 5 rivet, and diaphragm 3 is mounted between procapsid component 1 and back casing component 5,
Rear shell sealing gland 7 and back casing component 5 are interference fitted, and form sealing shell, and rear shell sealing gland 5 and valve body 2 are interference fitted, boosting disk 4
It is riveted with valve body 2, control valve member 8 and valve body 2 are assembled by the clamping of locking plate 6, and reaction plate 10, guard ring 12, master cylinder push rod 11 fill
It fits over inside valve body 2, return spring 13 is assemblied on guard ring 12, and dust cover 9 is assemblied on back casing component 5.
There are floating sealing structure 301, clamping location structure 302 on diaphragm 3, valve body 2 passes through floating sealing structure 301 and film
Piece 3 connects, and has one L1 of seal band and seal band two L2, L1 47.4mm, L2 49.3mm on floating sealing structure 301,
Boosting disk 4 is connect by being clamped location structure 302 with diaphragm 3.
Control valve member is pushed by brake pedal when work, drives control valve member to advance and cooperate with valve body, passes through film
Vacuum booster assembly is separated into vacuum chamber and atmosphere chamber by piece, using atmospheric pressure effect on diaphragm, power-assisted is driven to fold
It is acted on to power-assisted.
