Description of the Related Art In general, pneumatic tires used on roads are soft and highly elastic when the air pressure is low, providing good riding comfort, but the rolling resistance of the tires increases. On the other hand, it is known that when the air pressure of a tire is high, the tire becomes hard, but the tire ground contact area and tire deformation become smaller, and as a result, the rolling resistance during running is reduced.

This is true for a wheel (tire/rim assembly) 3 that is made up of a pneumatic tire (the cross section of the tire is shown with the ground contact surface facing upward) 1 and a rim 2 as shown in Figures 5 and 6. A liquid 5, which is an antifreeze liquid, is placed in a space 4 defined by a tire 1 and a rim 2. Normal air pressure P in pneumatic tire 1 is approximately 2 kg/cm.
2 air 7 is filled. Liquid 5 when driving at high speed
is dispersed around the outer periphery of the inner surface of the tire by centrifugal force, pressurizing the outer periphery of the inner surface of the tire and producing the effect of injecting the liquid 5.

When the wheels 3 are rotating at high speed, the liquid 5 is dispersed around the inner surface of the tire due to the centrifugal force caused by the rotation of the wheels 3. However, when the vehicle is stopped, that is, when the wheels 3
When the rotation is stopped, the liquid 5 accumulates in the lower part of the space 4, as shown in FIG. For this reason, there was a problem in that the liquid 5 splashed at the beginning of the vehicle and generated noise.

The air inlet 6a of the air valve 6 is located below the liquid 5.
If the space 4 is immersed in water, the liquid 5 will spray out from the air valve 6 and leak, creating a problem in that it is difficult to keep the amount of the liquid 5 in the space 4 constant. This invention was made by focusing on such a conventional problem, and a sponge-like liquid absorbing member with high liquid absorbing property is installed in the space defined by the tire and the rim, and when the rotation becomes low, By absorbing liquid and reducing the amount of liquid that accumulates under the tire when the vehicle is stopped or at very low speeds, the sound of liquid splashing and hitting the rim or tire when the vehicle starts can be reduced. , a tire that can maintain a nearly constant amount of liquid at all times.
An object of the present invention is to provide a rim assembly.

Apply pressure. When the tire rotates at low speed or comes to a standstill, the centrifugal force acting on the liquid decreases, causing
The liquid at the outer periphery of the space moves to the lower part of the space due to gravity, and is absorbed and held by the rotating liquid absorbing member, thereby significantly reducing the amount of liquid that accumulates at the lower part of the space.

First, the configuration will be explained. In FIG. 1, 11 is a tire/rim assembly, and the tire/rim assembly 11 (hereinafter simply referred to as a wheel) is a pneumatic tire (hereinafter simply referred to as a tire) 12 for a passenger car.
, a tubular rim 13 to which the bead portion 12a of the tire 12 is assembled, and an annular space 14 defined by the tire 12 and the rim 13. An air valve 16 for injecting air into the space 14 is provided in the rim 13 so as to have an opening 16a from the outside of the rim 13 to the space 14 inside. The space 14 is filled with air 19 having an air pressure P of about 2 kg/cm2 through an air valve 16, and a predetermined amount of antifreeze 20, which is a liquid, is injected.

ようになされている。[0009] Inside the space 14, there is provided a sponge-like liquid absorbing member 17, which is rectangular in cross section and arranged annularly along the outer periphery of the rim 13. The liquid absorbing member 17 is attached by adhesion or welding to the inside of the bead portion 12a of the tire 12 at a portion within the space 14 near the tire rotation center. The liquid absorbing member 17 is formed so that the cross-sectional height H17 from the bead base 12d of the tire 12 to the outer periphery does not contact the inner surface of the tire even if the tire is deflected during running. This is a sponge-like liquid absorbing member 17.
This is because when the liquid absorbing member 17 comes into contact with the inner surface of the tire and is deformed due to tire flexure, the work for deforming the liquid absorbing member 17 is added to the rolling resistance, which prevents the rolling resistance from decreasing. Further, the width W17 of the liquid absorbing member 17 in the direction of the rotation axis of the tire 12 in cross section is set to such an extent that it does not come into contact with the inner surface of the sidewall portion 12b on the inner surface of the tire even if the tire is deflected in the lateral direction during running. In cross section, the liquid absorbing member 17 has a plurality of holes 18 in the tire circumferential direction extending from the rim 13 side to the tread portion 12c side of the tire 12 at the center between the bead portions 12a of the tire 12. Air can be filled and released from the 13 side to the tread portion 12c side of the tire 12, and the liquid absorbing member 17 is prevented from being excessively deformed. The liquid absorbing member 17 is provided with cut recesses 17c in an inner portion 17a on the rim 13 side and an outer portion 17b on the tread portion 12c side, respectively, to reduce deformation of the liquid absorbing member 17.

２０の厚さｔを調整すればよい。Next, the operation will be explained. When the vehicle runs at high speed and the wheels 11 rotate at high speed, a centrifugal force proportional to the square of the rotational speed acts on the entire tire 12, causing the liquid absorbing member 1
The antifreeze 20 absorbed in the space 14 due to centrifugal force
The antifreeze liquid 20 moves in the circumferential direction along the outer circumference of the space 14, and the antifreeze liquid 20 adheres to the inner surface of the tire 12 with a substantially uniform thickness t, as shown in FIG. In this state, the air pressure P in the space 14 is at the inner and outer circumference of the tire 12.
In addition to this, a centrifugal force acting on the antifreeze 20 is added, resulting in an equivalent state in which the air pressure P appears to increase. The contact area of the tire 12 and the tire deformation are reduced by the increased pressure ΔP of the air pressure P, and the rolling resistance during high-speed running is reduced. In the case of an average tire (for example, a passenger car tire), the increased pressure ΔP increased by this centrifugal force is approximately 0.5 when the thickness t of the antifreeze liquid 20 is 1 cm and the vehicle speed is 120 km/h.
kg/cm2. This increased pressure ΔP is proportional to the thickness t of the antifreeze 20 and proportional to the square of the vehicle speed V. Therefore, in order to obtain the desired increased pressure ΔP, the amount of the antifreeze 20 injected into the space 14 must be adjusted. The thickness t of the antifreeze liquid 20 adhering to the inner surface of 12 may be adjusted.

The antifreeze liquid 20 in the space 14 tries to accumulate at the bottom of the space 14 of the tire 12 due to gravity, but it comes into contact with the liquid absorbing member 17 that is rotating at a low speed or is in a stopped state, and most of the antifreeze liquid 20 accumulates on the liquid absorbing member 17 around the entire circumference. Antifreeze that is absorbed and remains 20
However, as shown in FIG. 2, the particles accumulate in the gap below the space 14 within the tire 12. The amount of antifreeze 20 that accumulates at the bottom of the space 14 of the tire 12 is determined by the inner surface height H of the tire when the tire is deflected.
is determined by the difference between and the cross-sectional height H17 of the liquid absorbing member 17,
As the cross-sectional height H17 of the liquid absorbing member 17 approaches the tire inner surface deflection height H, the amount of antifreeze 20 that accumulates in the space 14 decreases significantly. Therefore, the movement of the antifreeze fluid 20 at the time of starting is small, and the sound of the antifreeze fluid 20 splashing and hitting the tires or rims can be significantly reduced.

Even when the air valve 16 is located below the tire 12, most of the antifreeze 20 is absorbed by the liquid absorbing member 17, and the amount of antifreeze 20 that accumulates at the bottom of the space 14 inside the tire 12 is greatly reduced. Since the antifreeze liquid 20 only slightly accumulates in the lower part of the space 14, that is, in the space 14 below the tire 12, the inner circumference of the space 14, that is, the space 14
There is no antifreeze 20 on the upper rim 13 side, and even if you open the air valve 16 and check the air pressure, the air valve 16
The liquid 20 hardly leaks from the tire 12, and the liquid 20 inside the tire 12 is always kept constant. Therefore, the effect of reducing rolling resistance during high-speed running can be maintained for a long period of time.
