Wheels with extended air tank

Abstract

To provide a wheel with an expansion air tank, which improves the ride comfort of a car even when the size is increased and can increase the strength of a tire. [Solution] In a wheel with an expansion air tank, an expansion air tank 4 for filling with air is placed at a depth from the outer periphery of an automobile wheel rim 6 to near the inner axle 8, and the brake components 9 that were previously stored inside the wheel are placed outside the wheel. The reinforcing material between the left and right wheel rims 6 has countless holes 7 at regular intervals that allow air 3 in the tire layer and air in the air tank 4 to flow back and forth. The width of the air tank 4 can be made wider than the width of the wheel rim, allowing the amount of air to be significantly increased.

Description

[Technical field]

[0001] The present invention relates to the addition of an expanded air tank within an automobile wheel. [Background technology]

[0002] Conventionally, automobile wheel rims have a large amount of unused space extending from the outer periphery to the inside. [Prior art documents] [Non-patent literature]

[0003] Catalogues of automobile tires and wheels, etc. Summary of the Invention [Problem to be solved by the invention]

[0004] If you increase the outer diameter of the wheel while keeping the outer diameter of the tire the same, the height of the tire will become smaller, resulting in a less comfortable ride.

[0005] In addition, if you reduce the outer diameter of the wheel, the tire height will increase, allowing for more air to be carried and improving ride comfort, but the tire's performance will deteriorate. [Means for solving the problem]

[0006] In this device, an air tank 4 for filling with air is placed in the large space from the outer periphery of an automobile wheel rim 6 to near the axle 8 at the inner depth. The brake components 9 that were previously mounted inside the wheel are placed outside the wheel, and the air tank 4 is extended to this area. Countless holes 7 are drilled at regular intervals in the reinforcing material between the left and right wheel rims 6, allowing air 3 in the tire layer and air in the air tank 4 to pass back and forth. The width of the air tank 4 for passenger cars can be roughly the same as or wider than the wheel rim width, and for trucks it is made wider than the wheel rim width to significantly increase the amount of air. Effect of the Invention

[0007] By putting a large amount of air into the air tank 4 inside the wheel, the amount of air increases significantly, improving the ride comfort of the car even if the wheels are enlarged.

[0008] In addition, improved ride comfort allows the car's suspension to be made cheaper, resulting in cost reduction.

[0009] Furthermore, if the tire width is expanded by about 1.4 times, the amount of air will be the same as two conventional truck tires, making it possible to convert the dual tires on the rear wheels of a truck into a wide single tire.

[0010] In addition, the strength of passenger car tires will increase, allowing the outer diameter of tires to be reduced, and living space will be increased. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] An expanded air tank 4 for filling with air is installed in a large space extending from the outer periphery of an automobile wheel rim 6 to the vicinity of an axle 8 at the inner depth.

[0013] Reinforcement material is inserted between the air layer 3 inside the tire and the air tank 4, and numerous holes 7 are drilled at regular intervals to allow air to pass between them.

[0014] In the passenger car wheels of Figures 1 and 2 and the truck wheels of Figures 3, 4, and 5, in order to increase the capacity of the air tank 4, the brake parts 9 that have been mounted inside the wheel up until now are arranged outside the wheel in order to accommodate the air tank 4. These are mainly intended for the rear wheels of automobiles.

[0015] In FIG. 2, the width of the air tank 4 is wider than the rim 6 toward the inside of the wheel, while in FIGS. 4 and 5, both sides protrude beyond the rim 6, suppressing the increase in tire width and significantly increasing the amount of air.

[0016] If the brake parts 9 cannot be arranged outside the wheel, they must be arranged inside the wheel, and depending on the extent of the arrangement, the air tank 4 is changed in shape to reduce its capacity so as not to come into contact with the brake parts 9, whether that be stored in about a quarter of the wheel width as in Figures 6 and 9, about half as in Figures 7 and 10, or about three-quarters as in Figures 8 and 11. The depth of part of the air tank 4 is arranged up to the vicinity of the axle 8. These are mainly oriented toward the front wheels of the automobile. [Explanation of symbols]

Claims

1. An air tank 4 for holding air is provided in a deep space extending from the outer periphery to the inside of an automobile wheel rim 6, but not touching the axle 8, and the brake parts 9 that were previously stored inside the wheel are now placed outside the wheel. The reinforcing material connecting the left and right wheel rims 6 has numerous holes 7 at regular intervals that allow air 3 in the tire layer and air in the air tank 4 to flow back and forth. The width of the air tank 4 can be made wider than the wheel rim width, making it possible to greatly increase the amount of air in the wheel shown in Figure 5.

2. When storing the brake parts 9 inside the wheel of claim 1, the air tank 4 is placed at a slight distance from the innermost side where the brake parts 9 can be attached so that the depth of a part of the air tank 4 can be maintained at the same level as in claim 1. The width of the air tank 4 on the inside of the wheel is made to be about the same as the rim 6, and the shape of the air tank 4 is changed so that the brake parts 9 do not come into contact with it, reducing the capacity of the wheel of Figure 10.
