Lifting lug connection is held in the palm, in addition the mounting means of traditional brake cylinder casing is that hole is opened on brake cylinder casing, and when installation is in through-hole two
End setting mounting plate is simultaneously installed, complex installation process in such a way that a connecting rod is fixed on a mounting board across through-hole, and tired
Product error is larger.
Summary of the invention
To solve problems of the prior art, the present invention provides tread braking unit brake cylinder casing, the checking cylinders
Body has structural strength higher, and safety is higher, and the service life is longer, gross weight is lower, the advantages that being easily installed.
To achieve the above object, the present invention adopts the following technical scheme:
Tread braking unit brake cylinder casing, including shell are set on the shell in parallel there are two cantilever, between the cantilever
It is connected by connecting plate, the cantilever is equipped with engaging lug far from one end of shell, is equipped with connection between two engaging lugs
Roller.
The housing side is equipped with threaded hole, and the threaded hole is for installing shell.
The shell, cantilever, engaging lug and connection roller are integrally formed.
In above structure, the shell is used to install each components of brake unit, when installing shell, passes through threaded hole
Directly shell is installed on rail vehicle truck, watt support sunpender of formula is integrally connected by the connection roller, and passes through one
A watt support sunpender for body formula connects watt base body.
Brake cylinder casing of the invention by integrated cantilever, connection roller, enable shell directly with watt of integral type
Sunpender connection is held in the palm, each structure-integrated molding reduces the error of accumulation, and whole turning is higher with precision, structural strength is higher,
So that safety is higher, the service life is longer.
Preferably, the housing side is equipped with installation pad, and the threaded hole is opened on installation pad, the installation pad and shell
It is integrally formed.
The depth of threaded hole can be increased by installing pad, shell peace can be improved in the case where not improving shell wall thickness
Stability when dress.
Preferably, fabrication hole is provided on the cantilever and connecting plate.
The setting of fabrication hole can mitigate shell gross weight in the case where not weakening structural strength.
Preferably, the shell, cantilever, engaging lug and connection roller are integrally formed using QT500-7 spheroidal graphite cast-iron.
It is integrally formed using QT500-7 nodular cast iron, gross weight is lower, and cantilever, connection roller, engaging lug is integrally formed so that peace
It fills more convenient.
Beneficial effect is:
1, brake cylinder casing of the invention by integrated cantilever, connection roller, enable shell directly with integral type
Watt support sunpender connection, each structure-integrated molding reduce the error of accumulation, whole assembly precision is higher, structural strength more
Height, so that safety is higher, the service life is longer, and cantilever, connection roller, engaging lug are integrally formed so that easier for installation；
2, the depth of threaded hole can be increased by installing pad, shell can be improved in the case where not improving shell wall thickness
Stability when installation；
3, the setting of fabrication hole can mitigate shell gross weight in the case where not weakening structural strength；
4, using QT500-7 nodular cast iron be integrally formed, gross weight is lower, cantilever, connection roller, engaging lug be integrally formed so that
It is easier for installation.

Specific embodiment
The present invention will be further explained below with reference to the attached drawings:
Embodiment 1:
As shown in Figure 1-Figure 3, tread braking unit brake cylinder casing, including shell 1, set that there are two cantilevers on shell 1 in parallel
2, it is connected between cantilever 2 by connecting plate 3, cantilever 2 is equipped with engaging lug 7 far from one end of shell 1, between two engaging lugs 7
Equipped with connection roller 4.
Shell 1, cantilever 2, engaging lug 7 and connection roller 4 are integrally formed using QT500-7 spheroidal graphite cast-iron.
1 side of shell is equipped with threaded hole 5, and threaded hole 5 is for installing shell 1.
Fabrication hole is provided on cantilever 2 and connecting plate 3.
The setting of fabrication hole can mitigate 1 gross weight of shell in the case where not weakening structural strength.
In above structure, shell 1 is used to install each components of brake unit, when installing shell 1, passes through threaded hole 5
