Abstract

A vehicle wheel, which is divided in an axial direction of a tire into two pieces which are an in-side half wheel and an out-side half wheel that are connected to each other and fixed to an axle hub, includes wheel coupling bolts joining a mating surface of the in-side half wheel and a mating surface of the out-side half wheel together, and hub bolts joining the out-side half wheel and the axle hub together. The wheel coupling bolts and the hub bolts are respectively screwed into nuts from the out-side half wheel side.

First claim

The invention claimed is:

1. A vehicle wheel divided in an axial direction of a tire into two pieces which are an inside half wheel and an outside half wheel that are connected to each other and fixed to an axle hub, the vehicle wheel comprising:
first bolts joining a first mating surface of the inside half wheel and a second mating surface of the outside half wheel together;
second bolts joining the outside half wheel and the axle hub together; and
a first cover body covering first nuts that are screwed onto the first bolts, the first cover body being jointed by second nuts that are screwed onto the second bolts,
wherein the first bolts are screwed into the first nuts from an outside half wheel side, and the second bolts are screwed into the second nuts from the outside half wheel side,
a protruding portion protruding from the first mating surface is formed on the first mating surface and extends over an entire circumference of the inside half wheel, and
a recessed portion engaged with the protruding portion is formed on the second mating surface and extends an entire circumference of the outside half wheel.

2. The vehicle wheel according to claim 1 , further comprising
a second cover body covering the first bolts that are arranged at the inside half wheel side.

3. The vehicle wheel according to claim 2 , wherein
the inside half wheel is provided with an insertion hole communicating with a rim outer circumferential surface of the inside half wheel,
a whistle mechanism section that is fixed by a third nut and emits a warning sound due to air flowing through the insertion hole toward an inner circumference side from a rim outer circumference side is mounted at an end portion on the rim inner circumference side of the insertion hole, and
the second cover body is jointed by the third nut of the whistle mechanism section.

4. A running wheel comprising:
the vehicle wheel according to claim 3 ; and
the tire mounted on the vehicle wheel.

5. A vehicle comprising the running wheel according to claim 4 .

6. A running wheel comprising:
the vehicle wheel according to claim 2 ; and
the tire mounted on the vehicle wheel.

7. A vehicle comprising the running wheel according to claim 6 .

8. A running wheel comprising:
the vehicle wheel according to claim 1 ; and
the tire mounted on the vehicle wheel.

9. A vehicle comprising the running wheel according to claim 8 .

10. A method of assembling and disassembling the vehicle wheel according to claim 1 which is provided with the tire, the method comprising:
a first step of detaching the second bolts by loosening the second nuts from an outside of the outside half wheel;
a second step of reducing inner pressure by releasing air in the tire;
a third step of detaching the first bolts by loosening the first nuts from the outside of the outside half wheel; and
a fourth step of separating the inside half wheel and the outside half wheel and detaching the inside half wheel and the outside half wheel from the tire,
wherein the disassembling of the vehicle wheel is performed in order from the first step to the fourth step when the vehicle wheel is detached from the tire, and
the assembling of the vehicle wheel is performed in reverse order of the disassembling when the vehicle wheel is mounted on the tire.
