Description of the embodiments
In order to make the objects, technical solutions and advantages of the present utility model more apparent, the present utility model will be further described in detail with reference to the accompanying drawings and examples.
Examples
As shown in fig. 1, the trapezoid wheel hub comprises a wheel hub body 1 and a wheel rim 4 connected with the wheel hub body 1 into a whole, wherein the section of the wheel rim 4 is in a conical structure with large outside and small inside; a left flange 2 is arranged at the end part of the rim 4, a left bead seat 5 is arranged at the root part of the left flange 2, a right flange 3 is arranged on the circumference of the outer diameter of the hub body 1, a right bead seat 6 is arranged at the root part of the right flange 3, and the maximum outer diameters of the left flange 2 and the right flange 3 have a difference value, namely the maximum outer diameter C of the left flange 2 is smaller than the maximum outer diameter A of the right flange 3; the taper of the rim 4 is 2 °. The difference between the maximum outer diameters of the left flange 2 and the right flange 3 is 8mm.
Referring to fig. 2, the rim 4 of the trapezoidal hub of the present utility model may have another form, i.e. the cross section of the rim 4 is in a conical shape with a smaller outside and a larger inside, but the width B of the hub is unchanged, where the maximum outer diameter C of the left flange 2 is smaller than the maximum outer diameter a of the right flange 3.
Referring to fig. 3, the utility model further provides a tire matched with the trapezoid wheel hub, which comprises a tire crown 7, a left tire wall 8 and a right tire wall 9 connected to two sides of the tire crown 7, wherein a left toe opening 10 and a right toe opening 11 are respectively arranged on the inner diameter circumferences of the left tire wall 8 and the right tire wall 9, the minimum inner diameter of the left toe opening 10 is larger than the minimum inner diameter of the right toe opening 11, and the left toe opening 10 and the right toe opening 11 are respectively matched with the left tire lip seat 5 and the right tire lip seat 6. The right tire wall 9 is higher than the left tire wall 8, the wall thickness of the right tire wall 9 is higher than the wall thickness of the left tire wall 8, and the wall thickness of the right tire wall 9 gradually thins towards the right toe opening 11. The wall thickness of the right side of the crown 7 is larger than that of the left side, and the wall thickness of the right side of the crown 7 gradually becomes thinner towards the center of the crown 7.
