Vehicle axle air chamber support assembly, including back-plate, air chamber support, it is characterized in that, the air chamber support assembly further includes cam sleeve and camshaft, air chamber support is arranged on one end of camshaft, back-plate is set to the other end of camshaft, and air chamber support, cam sleeve and back-plate are integrally formed, and camshaft, which is worn to be connected in cam sleeve and pivot with cam sleeve, to be coordinated.The cam sleeve, back-plate and air chamber support of the utility model are integrally formed, it is ensured that the concentricity of axis hole inside cam sleeve；It is meanwhile integrally formed simple in structure so as to be installed between back-plate and air chamber support without connectors such as bolts, simplify structure and assembly technology, reduced manufacture cost, improve production efficiency；And solve the problems, such as that air chamber support and back-plate are poor due to assembly precision caused by mismachining tolerance.
Description
Technical field
The utility model is related to motor vehicle spare and accessory parts technical fields, and in particular to a kind of vehicle axle air chamber support assembly.
Background technology
It is to realize fixation by the way of assembling in the general hanging type air chamber support assembly of existing vehicle axle,
Air chamber support is fixedly connected on back-plate using bolt, as Publication No. CN202193074 patent document in it is public
A kind of novel air chamber bracket assembly device opened is support plate and the braking bottom being fixedly connected using bolt on air chamber support
Plate, realization air chamber support are fixedly connected with back-plate.Since back-plate and air chamber support are that separate machined is molding,
The precision of processing it is difficult to ensure that, meanwhile, can also assembly precision be caused a degree of influence by being fixed by bolts, for example,
After being bolted, it is difficult to ensure that cam shaft mounting hole on the gentle room stent of cam shaft mounting hole on back-plate is same
Axis degree, this just directly affects the rotation flexibility of camshaft, so as to influence the reaction time of arrestment mechanism, efficiency and braking
Stability；And since the requirement on machining accuracy to each component is higher, this must for split type back-plate and air chamber support
So cause its processing technology complex, and it is also relatively high to manufacture cost.
Utility model content
In view of the deficiencies of the prior art, the purpose of this utility model is intended to provide a kind of vehicle axle air chamber support total
Into, it can be under the premise of structure and processing technology be simplified, the concentricity of guarantee cam shaft mounting hole is eliminated assembling and is missed
Difference.
To achieve the above object, the utility model adopts the following technical solution：
Vehicle axle air chamber support assembly, including back-plate, air chamber support, which is characterized in that the air chamber support assembly
Cam sleeve and camshaft are further included, air chamber support is arranged on one end of camshaft, and back-plate is set to the another of camshaft
One end, and air chamber support, cam sleeve and back-plate are integrally formed, camshaft, which is worn, to be connected in cam sleeve and and camshaft
Set pivots cooperation.
Air chamber support along the cantilever to extend radially outwardly of cam sleeve and is connected to including one end by cam sleeve
The fixed seat of the end of cantilever offers mounting hole in fixed seat.
Air chamber support and back-plate are respectively placed in the both sides of cam sleeve.
The part that back-plate is connected with cam sleeve has one around the ribs for being located at cam sleeve outer peripheral edge.
The beneficial effects of the utility model are：
Compared with the prior art, the cam sleeve of the utility model, back-plate and air chamber support are integrally formed, it is ensured that
The concentricity of axis hole inside cam sleeve；It is meanwhile integrally formed simple in structure so that between back-plate and air chamber support
It is installed without connectors such as bolts, simplifies structure and assembly technology, reduced manufacture cost, improve production efficiency；
And solve the problems, such as that air chamber support and back-plate are poor due to assembly precision caused by mismachining tolerance.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
In the following, with reference to the drawings and specific embodiments, the utility model is further described：
As shown in Figure 1, a kind of vehicle axle air chamber support assembly for the utility model, including back-plate 30, gas
Room stent 20, cam sleeve 10 and camshaft 40, wherein, air chamber support 20 is located at one end of cam sleeve 10, back-plate
30 are located at the other end of cam sleeve 10, and air chamber support 20 and cam sleeve 10 are spaced a distance, to match vehicle axle
The installation of other upper parts；Above-mentioned air chamber support 20, back-plate 30 and cam sleeve 10 is an integral molding structure,
Can be specifically to be process or forge to be process by casting technique.Camshaft 40, which is worn, is connected on cam sleeve 10
In, and camshaft 40 can be rotated relative to cam sleeve 10.
In the utility model, cam sleeve 10, back-plate 30 and air chamber support 20 are integrally formed, it is ensured that camshaft
Cover the concentricity of 10 inside axis holes；It is meanwhile integrally formed simple in structure so that nothing between back-plate 30 and air chamber support 20
The connectors such as bolt is needed to be installed, simplify structure and assembly technology, manufacture cost is reduced, improves production efficiency；And
And solve the problems, such as air chamber support 20 and back-plate 30 since assembly precision caused by mismachining tolerance is poor.
In the utility model, air chamber support 20 includes a cantilever 21 and fixed seat 22, and cantilever 21 is by cam sleeve 10
One end extends radially outwardly along cam sleeve 10, and fixed seat 22 is shaped in the end of cantilever 21, in fixed seat 22
Mounting hole is provided with, for installing gas chamber.
In order to further be adapted to the installation of other parts in vehicle bridge, on the basis of said program, this practicality is new
The air chamber support 20 and back-plate 30 of type are located at the both sides of cam sleeve 10 respectively, i.e. air chamber support 20 is located at cam sleeve 10
Upside, back-plate 30 then be located at cam sleeve 10 downside.
The portion that back-plate 30 is connected with cam sleeve 10 has one around the ribs 31 for being located at 10 outer peripheral edge of cam sleeve,
I.e. in the end set of cam sleeve 10 ribs 31, when 30 stress of back-plate exerts a force to cam sleeve 10, the reinforcement
Rib 31 can reduce stress concentration of the cam sleeve 10 in the end, and play the role of reinforcement to cam sleeve 30 at this,
So as to prevent cam sleeve 30 from being deformed upon at this, the normal work of camshaft 40 is influenced.
It is noted that the above structure of the utility model, is applicable not only to the preceding bridge of vehicle, is equally applicable to vehicle
Rear axle
Above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to aforementioned reality
Example is applied the utility model is described in detail, it will be understood by those of ordinary skill in the art that, it still can be to preceding
The technical solution recorded in each embodiment is stated to modify or to which part technical characteristic progress equivalent replacement, and these
Modification is replaced, the spirit and model of various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
It encloses.
