Preferably, the height of described interconnecting gangway is less than the height of described connecting portion.
Preferably, described front wheel hub is also connected by flathead screw with described brake wheel.
More preferably, described tire bolt has six, and described flathead screw has two.
Preferably, described front wheel hub is provided with ABS gear ring.
Preferably, described tire bolt is disposed with interference section, light face section and thread segment from head to bar portion, described interference section and described front wheel hub interference fit, and described light face section is corresponding with the part of mounting hole on described brake wheel.
More preferably, the outside face of described interference section is provided with annular knurl line.
The front wheel hub band brake drum assembly that the utility model provides is by the setting of the interconnecting gangway of circular arc, the stress dispersion be conducive to interconnecting gangway is concentrated weakens, and circular arc bends towards inside brake drum, larger deflection can be provided when power is passed to front tyre by brake wheel, thus avoid brake wheel to produce slight crack better, ensure the use of front wheel hub band brake drum assembly.

Detailed description of the invention
For enabling above-mentioned purpose, the feature and advantage of utility model more become apparent, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
As shown in Figures 2 and 3, the front wheel hub band brake drum assembly that the utility model provides, comprise front wheel hub 1, brake wheel 2 and tire bolt 3, described brake wheel 2 comprises the shoulder 21, interconnecting gangway 22 and the connecting portion 23 that connect in turn, wherein, described interconnecting gangway 22 is a circular arc, and the bending direction of described circular arc is towards the inside of described brake wheel 2, and the radius of described circular arc is 510mm-550mm.
The front wheel hub band brake drum assembly that the utility model provides is by the setting of the interconnecting gangway 22 of circular arc, the stress dispersion be conducive to interconnecting gangway 22 is concentrated weakens, and circular arc is towards brake wheel 2 interior curve, larger deflection can be provided when power is passed to front tyre by brake wheel 2, thus avoid brake wheel 2 to produce slight crack better, ensure the use of front wheel hub band brake drum assembly.
In order to better the stress dispersion that interconnecting gangway 22 is concentrated be weakened, and ensure the transmission efficiency of steering effort from connecting portion 23 to interconnecting gangway 22 and shoulder 21, the height L1 of described interconnecting gangway 22 is less than the height L2 of described connecting portion 23, the height L1 of above-mentioned interconnecting gangway 22 refers to the length of interconnecting gangway 22 in the vertical direction, and the height L2 of above-mentioned connecting portion 23 refers to the length of connecting portion 23 in the vertical direction.
In order to prevent steering effort before front wheel hub 1 to be passed in the process of brake wheel 2 both between connection loosen, described front wheel hub 1 is also connected by flathead screw 4 with described brake wheel 2, it should be apparent to those skilled in the art that, above-mentioned flathead screw 4 can select cross recessed countersunk head sscrew, with installation easy to use.Further, in order to ensure the stable connection between front wheel hub 1 and brake wheel 2, described tire bolt 3 has six, and described flathead screw 4 has two, tire bolt 3 can distribute at the surface uniform of front wheel hub 1, and flathead screw 4 can be symmetrical arranged on the surface of front wheel hub 1.
