Portion 52, abutting part 52 are located between wheel hub 10 and filling tire 30, and the side of abutting part 52 is abutted with wheel hub 10, the other side and filling
Tire 30 abuts, and in this present embodiment, the outside of abutting part 52 is abutted with wheel hub 10, and inside is abutted with filling tire 30, so that outside
Tire 50 will not slide.There are multiple grooves 511 in rolled portion 52, not only alleviated the quality of cover tire 50 but also cover tire 50 is had
There is antiskid function, in this present embodiment, abutting part 52 can also extend embedded division 53, and embedded division 53 is located at wheel hub 10 and filling
In buffer area 20 between tire 30, the setting of embedded division 53 enables cover tire 50 easily loaded on wheel hub 10.For wheel hub 10
For, specifically, wheel hub 10 has the first chimb 11 and the second chimb 12, the first chimb 11 and the second chimb 12 and abutting part 52
It abuts, forms a recess portion 13 between the first chimb 11 and the second chimb 12, the protrusion 31 of filling tire 30 is embedded in recess portion 13, convex
The height in portion 31 is less than the depth of recess portion 13, so that forming buffer area 20 between protrusion 31 and recess portion 13.Using the first chimb 11
It is abutted with the second chimb 12 with abutting part 52, so that abutting part 52 resists filling tire 30, so that filling tire 30 is fixed on
Without sliding on wheel hub 10.
Compared with the superior, wheel hub 10 further includes support portion 15, and along being arranged radially for wheel hub 10, support portion 15, which is used to support, to be carried on
Pressure on wheel hub 10, support portion 15 include at least one be arranged side by side supporting element 151, supporting element 151 include at least one simultaneously
The support column 152 of setting is arranged, in order to provide better support effect, the quantity of supporting element 151 and support column 152 is preferably multiple
Number, such as 2,4,8 etc., it, more preferably respectively will be a plurality of when using a plurality of supporting elements 151 and support column 152
Supporting element 151 and support column 152 are arranged side by side, and in this present embodiment, support portion 15 includes 2 supporting elements 151 arranged side by side,
Supporting element 151 can be improved the support of support portion 15 using the design of double side-by-sides including 2 support columns 152 arranged side by side
Power prolongs its service life, due also to this structure makes it form two isosceles triangles with 10 surface of wheel hub, increases the wheel hub
10 stability in rotation.
- 5 are continued to refer to figure 1, the imitative pneumatic tire 100 of the utility model further includes wheel cap 70, is installed on wheel hub 10, is taken turns
The centre of hub 10 is used to install transmission shaft, has more screw at the position of installation transmission shaft, outside wheel hub 10 again
Cover a wheel cap 70, it appears that it is relatively beautiful, and also wheel cap 70 has the function of antirust waterproof to the part covered in wheel hub 10,
So that the screw of the part is not allowed perishable, the outside of wheel cap 70 is circle, and the side that wheel cap 70 is inserted into wheel hub 10 has multiple
Back-off portion 71 accordingly referring to FIG. 3, wheel hub 10 is equipped with the engaging portion 16 cooperated with back-off portion 71, is installed in wheel cap 70
When wheel hub 10, back-off portion 71 and engaging portion 16 carry out snapping, keep wheel cap 70 not easy to fall off, it is preferable that wheel cap 70 is additionally provided with fixed
Position portion 72 can be good at installing wheel cap 70 with wheel hub 10, saves the time using the positioning region 72.
Filling tire 30 in the imitative pneumatic tire 100 of the utility model be it is solid, do not need to be inflated, the filling tire 30
By PP expect it is foam filled form, density is small, light weight, and it is recyclable recycle, it is also very friendly to environment, belong to environmental protection and fill out
