Abstract

PURPOSE:To improve the cooling effect of a wheel by providing a cylindrical space section in a rim well section to form a double wall section, sucking air from the well section, and exhausting it to the well section through the double wall space section. CONSTITUTION:When a wheel is rotated in the V direction, the air at the rim circumferential side flows into a cylindrical space section 4 through an induction guide 8 and an air circulation port 6. This air absorbs heat through the thin plate 3 of the cylindrical space section 4 and cools the external side space and then is exhausted from an air outflow port 7. As a result, the heat in a tire is exhausted and is cooled effectively, and the life of the tire can be prolonged.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an air-cooled boiler that actively radiates heat stored in wheels and tires.

Conventional wheels and tires generate heat due to brakes, friction between the tires and the road surface, and heat generated by tire deformation.
The temperature is raised. The heat stored in the wheels and tires is
Conventionally, heat was dissipated from the surface of wheels and tires, but heat dissipation was not necessarily sufficient under harsh conditions, and from the viewpoint of tire life and brake performance, W4
It was highly desirable to air-cool the wheels.

Purpose of the Invention In order to meet such demands, the present invention aims to improve the air cooling effect in the wheel.

Description and operation of the invention In order to achieve this object, in the air-cooled wheel of the present invention, a double wall part is provided in the well part of the rim, and a cylindrical space part is formed between the double walls, In addition, a plurality of air flow holes are provided in the rim well portion, and an air introduction guide and an air outlet guide are provided on the inner peripheral side of the rim of the air flow holes.

In such a wheel, the annular space surrounded by the tire and the rim is adjacent to the cylindrical space via the outer wall of the double wall.

A large amount of air is actively taken in and flows into the cylindrical space by the air introduction guide, and the annular space surrounded by the tire and rim is effectively cooled by this large amount of air flow. The purpose of the period is achieved.

Embodiments Below, preferred embodiments of the air-cooled wheel of the present invention will be described with reference to the drawings.

1 and 2 show a first embodiment of the present invention applied to a wheel with a shallow rim. In the figure, the wheel consists of a rim base 1 and four nod rings 2. The side link 2 has one cut 28 in the circumferential direction, and is elastically fitted to the rim base 1. rim base 1
consists of a flange portion 1a at the end, a tire bead seat 1b connected to the flange portion 1a, and a shallow well portion 1C connected to the tire bead seat 1b.

A thin plate 3 with good thermal conductivity is attached to the outer circumferential side of this shallow well part 1C, and the well part 1C is connected to the rim well part 1.
It is formed into a double-walled R structure of C and a thin plate 3. A cylindrical space 4 is formed between the rim well portion 1C and the thin plate 3.

The cylindrical space 4 may extend over the entire circumference, or may extend over the entire circumference.
As shown in the figure, a plurality of them may be partially provided on the circumference. In the case of a tubeless tire, the thin plate 3 hermetically isolates the cylindrical space 4 from a space 5 on the outer peripheral side of the rim, that is, a space surrounded by the rim and the tire.

A plurality of air circulation ports 6.7 are formed in the rim well portion 1C as openings for communicating the cylindrical space 4 with the atmosphere and for introducing or outflowing air into the cylindrical space 4. An air introduction guide 8 is provided inside the air circulation opening 6, and an air outflow guide 9 is provided inside the remaining air circulation lower part. In the first embodiment,
The air inlet guide 8 and the air outlet guide 9 consist of a jy ring. The cowling as the air introduction guide 8 and the cowling as the air outflow guide 9 are attached so that their frontage directions are opposite to each other. That is, the cowling as the air introduction guide 8 opens toward the front in the direction of wheel rotation when the vehicle moves forward (in the direction of ■ in the figure), and the cowling as the air outflow guide 9 opens toward the rear in the rotation direction of the wheel. It has a frontage towards the frontage. Figures 1 and 2 show a plurality of cowlings arranged in a row on the circumference.
A case is shown in which the opening direction of the cowling is alternately changed and air introduction guides 8 and air outflow guides 9 are provided alternately. - FIG. 3 shows a second embodiment of the invention.

In this embodiment, the air introduction guide 8 and the air outflow guide 9 are connected to the air flow opening 6.7 of the rim well portion 10, instead of having a structure for attaching a nozzle ring as shown in FIGS. 1 and 2. It is formed by cutting one side of a part and bending it toward the inner circumference.

FIG. 4 shows a third embodiment of the invention.

In this embodiment, the air introduction guide 8 and the air outflow guide 9 have cuts on three sides of the portion that will become the air circulation opening 6.7, regardless of the structure in which the cowling is attached as shown in FIGS. 1 and 2. It is made by inserting the material and bending it toward the inner circumference. In this case, the guide 8.9 is connected to the rim well part 1C with a remaining piece.

Further, FIG. 5 shows a fourth embodiment of the present invention. In this embodiment, the air flow port 6.7, the air introduction guide 8
Unlike the case where the air outflow guides 9 are provided in one row in the circumferential direction, they are provided in multiple rows (two rows in the figure).

In each of the embodiments configured as described above, cooling is performed as follows. That is, when the wheel rotates in the V direction, the air (J) on the inner circumferential side of the rim is collected and guided by the air introduction guide 8 and flows into the cylindrical space 4 through the air flow opening 6. The amount of air is large due to the presence of the air introduction guide 8.

A large amount of air flowing into the cylindrical space 4 efficiently cools the outer peripheral space 5 of the rim via the thin plate 3 with good heat conduction, and the air itself becomes humid and exits from the air outflow lower. . This releases the heat inside the tire to the outside. Since the air outflow lower has an air outflow guide 9, air is sucked out.

Effects of the Invention Therefore, according to the present invention, an air flow is generated in the cylindrical space 4 of the rim by the rotation of the wheel, and the tie A is
Since the heat inside the tire 7 can be released to the outside, it is possible to improve the shortened tire life and poor running performance caused by heat generation in the tire. This is particularly effective for wheels whose strength and physical properties deteriorate due to heat, such as resin wheels, or wheels made of materials with poor thermal conductivity.
