Description

Integrated seat and tire with the integrated seat

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of vehicle tires, and more particularly to an integrated seat and a tire in which the integral seat is mounted. Background technique

At the present time, the large-scale engineering vehicle is widely used in the mining and construction of the large-scale open-pit mines, and the tires of the large-sized vehicles are also very large, generally having a diameter of 3. 2m-4. 2m When the tire is mounted on the rim body, the retaining ring is an important component. As shown in Fig. 1, the retaining ring is formed by splicing the two parts of the seat and the shackle. As shown in Fig. 2, the dam is attached to the tire tread portion, and the shank is inserted between the rim body and the bottom of the tire tread. Finally, the lock is fastened to the outer edge of the rim to fix the seat. When the wheel is rotated and subjected to load, the seat and the shackle are engaged. However, in the above technical solution, when disassembling the tire, it is necessary to open the retaining seat by means of the disassembly tool and by manpower, because the retaining seat may cause a bite during the operation, which makes the disassembly and assembly difficult, if improperly operated. , easy to cause the block to collapse and hurt people.

Summary of the invention

SUMMARY OF THE INVENTION The present invention is directed to overcoming the above-discussed deficiencies of the prior art and provides an integral seat that is mounted between the rim body and the tire to facilitate disassembly and disposal of the tire. In order to achieve the above object, the present invention provides an integral seat which is installed between a rim body and a tire, and includes: a seat body formed by a seat A and a seat B, and a seat A On the rim body and in contact with the bottom of the tire tread, the seat B is fitted with the tire tread portion, and a bolt hole is arranged on the seat B along the tire tread portion; the support plate is mounted on the seat B and the tire tire Between the jaws, and the bolt holes are aligned with the support plate. When the tire is disassembled, the bolt plate is screwed into the bolt hole to drive the support plate to press the tire tread portion to separate the seat body from the tire.

In the above technical solution, the retaining groove I for completely accommodating the support plate is provided on the side wall of the tire 踵 portion of the seat 贴B. The present invention also provides a tire in which the integral seat is mounted, and a retaining groove II capable of completely accommodating the support plate is provided at the tread portion of the tire. Compared with the prior art, the invention has the following beneficial effects: By adding a support plate, when the tire is disassembled, the support plate is pressed against the tire tread portion to separate the seat cymbal from the tire, which is convenient and safe to disassemble; The side wall of the tire-fitted tire tire is provided with a retaining groove I for completely accommodating the support plate to avoid wear of the tire and the seat and improve the service life of the tire. Or, in the tire's tire part, there is a retaining groove II that can completely accommodate the support plate, which can also improve the service life of the tire, and can enhance the strength and service life of the seat.

The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The integrated seat of the invention is mainly designed for the difficulty of disassembly and assembly of the existing tires, and even in the case of improper operation, it is easy to cause work accidents. As shown in FIG. 1 to FIG. 2b, firstly, an existing retaining seat and its mounting on the tire 30 are combined. The assembly method is described. The retaining ring is formed by splicing the dam 10 and the seat cymbal 20. When the tire is specifically assembled, the dam 10 is attached to the tire tread portion 302 (see Fig. 2b). The shackle 10 is mounted between the rim body 40 and the tire tread bottom 301 (see FIG. 2b). Finally, the lock cymbal 50 is engaged with the outer edge of the rim body 40 for fixing the seat 20, and the wheel is rotated and loaded. In this case, the seat 20 is engaged with the dam 10. When disassembling the tire, it is necessary to open the retaining seat by means of the disassembly tool and relying on manpower. Since the retaining seat is occluded during operation, it is easy to cause disassembly and assembly, and even the improper operation, the retaining seat is easy. Bail out and hurt people.

As shown in FIG. 3a to FIG. 3c, the integrated seat provided in the embodiment can avoid the phenomenon of the snap-in occlusion occurring during the rotation of the wheel, and can conveniently and quickly disassemble the tire. The integrated seat of the present invention is installed at Between the rim body 40 and the tire 30, the seat body 1 and the support plate 2 are provided. The seat body 1 is composed of a seat A (reference numeral 12, the same below) and a seat B (reference numeral 11, the same below) In one piece, the seat A is placed on the rim body 40 and is in contact with the tire tread bottom 301 (see Fig. 4), and the seat B is fitted to the tire tread portion 302 (see Fig. 4), along the seat B Bolt holes (not marked in the figure) are provided in the direction of the tire tread. The support plate 2 is an annular plate which is installed between the seat B and the tire tread portion 302, and the bolt holes are aligned with the support plate 2. When the tire is disassembled, the bolt hole 3 is screwed into the bolt hole to support the support plate 2, and the support is supported. The plate 2 bears against the tire tread portion 302 to separate the seat body 1 from the tire 30. When disassembling the tire, it can also be disassembled by the hydraulic vehicle dismounting tool instead of the bolt 3. Specifically, the hydraulic dismantling tool is fixed in the dismounting groove 14 of the seat body 1 (see Fig. 5b), and the core of the hydraulic dismantling tool is removed. The rod extends into the bolt hole against the support plate 2, and the support plate 2 then bears against the tire tread portion 302 to separate the seat body 1 from the tire 30. As shown in FIG. 5a and FIG. 5b, in order to avoid the tire service life becoming shorter due to the wear of the support plate 2 on the tire crotch portion 302, the present embodiment provides a preferred embodiment in which the seat b is fitted to the side of the tire tread portion 302. The wall is provided with a retaining groove I (reference numeral 13, see Fig. 4) which can completely accommodate the support plate 2. When the seat body 1 is installed in the tire tread, the support plate 2 is just embedded in the retaining groove I (see Fig. 5b), the outer surface of the support plate 2 is flush with the side wall of the seat-fitting tire tread portion 302 such that the outer surface of the seat is in perfect contact with the tire tread portion 302. As shown in FIG. 6a and FIG. 6b, since the seat body needs to bear a large load on the tire, the groove on the side wall of the tire 踵贴贴会会会会会会会会会会会会会会 , , , , , , , , The invention also provides a tire for mounting the integral seat provided by the above embodiment, in particular, a retaining groove II (not labeled) capable of completely accommodating the support plate 2 is provided at the tire tread portion of the tire, in the installation In the case of a tire, the support plate 2 can be embedded in the retaining groove II of the tire (see Fig. 6b), and the outer surface of the support plate 2 is flush with the side wall of the tire tread portion 302, so that the outer surface of the seat B and the tire tread portion The 302 fits snugly, so that the groove is formed on the side wall of the tire tread portion 302, but the strength of the seat is enhanced, the service life of the seat is prolonged, and the tire is easily disassembled and assembled.

The above disclosure is only the specific embodiment of the present invention, but the present invention is not limited thereto, and any changes that can be made by those skilled in the art should fall within the protection scope of the present invention.
