Specific implementation mode
The embodiments of the present invention are described in detail below in conjunction with attached drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
As Figure 1-Figure 2, the utility model embodiment discloses a kind of empty iron bogie travelling wheel, including rubber layer
2 and wheel rim 1, wheel rim 1 is that the aluminium alloy of medial recess casts tray type structure, and the structure is empty with larger assembly in wheel rim 1
Between, it is easy to implement the densification of sky iron bogie, the edge of the wheel rim 1 is along its one annular portion 11 of axially extending formation, in annulus
The outside vulcanization in portion 11 is connected with rubber layer 2, in the present embodiment, inclined surface is symmetrically arranged in the both ends of the surface of rubber layer 2
21, in the case where being squeezed power, the deformation of rubber layer 2 is reasonable, can extend its service life, to make vulcanised rubber layer
Length of outer side is less than inside length.Wherein, abrasion limit markers are provided on inclined surface 21, which is rubber material
The columnar protrusions 22 of matter, and the extending axially outward along wheel rim 1 of columnar protrusions 22.Wherein, travelling wheel closes aluminium when making
The wheel rim 1 of golden material is put into sulfurizing mould, after mold closing, rubber is injected in sulfurizing mould and is vulcanized, the rubber of injection is made
Vulcanization forms rubber layer 2, and integral with 3 shape of wheel rim, while being integrally formed out column on the inclined surface of rubber layer 2 21 and dashing forward
22 are played, the columnar protrusions 22 are convenient for observation rubber running wheel abrasion, convenient for replacing in time.
In the present embodiment, wheel rim 1 is provided centrally with first through hole 12, and the external circumferential of first through hole 12 is evenly equipped with more
A stepped hole 13 for being used for installation bolt, further connecting bogie axle.
