Embodiment 1

[0022] figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. Such as figure 1 As shown, a vehicle tire safety insurance device includes an engineering plastic ring that is arranged inside the tire and surrounds the hub. The engineering plastic ring is formed by connecting two or three arc-shaped bodies 1. A metal structure 2 is arranged inside, and the metal structure 2 is set according to the curved shape and structure of the arc body 1; the metal structure 2 can be made of steel, aluminum, alloy and other plates, profiles or pipes. The metal structure 2 can enhance the internal rigidity of the arc body 1, increase the compressive strength, and ensure that the arc body 1 will not break and disintegrate when the vehicle continues to drive on bad roads or tire blowouts.

[0023] A through hole 3 is set on the metal structure 2, and the shape of the through hole 3 can be regular or irregular in shape according to the structure of the arc body ...

Embodiment 2

[0027] image 3 It is a sectional view of Embodiment 2 of the present invention. Such as image 3 As shown, the cross-sectional shape of the metal structure 2 is a hollow circular pipe. The inner diameter Φ of the circular pipe is 10-30 mm, and the thickness S of the pipe wall is 2-3 mm. For the arc body 1 provided with a through hole, the circular pipe can be arranged at the lower part or the upper part of the cross section of the arc body 1 . For the arc-shaped body without through holes, the circular pipe can be arranged in the lower part, upper part or middle part of the cross-section of the arc-shaped body 1 . For the arc-shaped body 1 of a heavy vehicle tire, two or more circular pipes can be arranged in the arc-shaped body 1 . In order to enhance the binding force and reduce the weight, a certain number of through holes can be arranged on the surface of the circular pipe.

Embodiment 3

[0029] Figure 4 It is a sectional view of Embodiment 3 of the present invention. Such as Figure 4 As shown, the cross-sectional shape of the metal structure 2 is a hollow triangular pipe. The thickness S of the pipe wall is 3-5 mm. For the arc body 1 provided with through holes, the triangular pipe can be arranged at the lower or upper part of the cross section of the arc body 1 . For the arc body without through holes, the triangular pipe can be arranged at the lower part or the upper part or the middle part of the cross section of the arc body 1 . For the arc-shaped body 1 of a heavy vehicle tire, multiple triangular-shaped pipes can be arranged in the arc-shaped body 1 . In order to enhance the binding force and reduce the weight, a certain number of through holes can also be arranged on the surface of the triangular pipe.

Abstract

The invention belongs to the field of transportation vehicles, and especially relates to a vehicle tire safety device. The device comprises a plastic annular part surrounding a hub and arranged in a tire. The plastic annular part is obtained by connecting two or three arc bodies. A metal structural body is arranged in the arc bodies. The metal structural body is configured according to the curved shape and structure of the arc bodies. The cross section of the metal structural body is hollow or solid rectangular, circular, triangular, horizontal-I shaped, I-shaped, +-shaped, or x-shaped. According to the vehicle tire safety device provided by the invention, metal structural body strength is ensured, metal structural body integral weight is minimized, and arc body rigidity and compressive strength are effectively enhanced, such that danger to vehicle driving caused by arc body breakage or disintegration is avoided, and vehicle continuation distance on bad road and under flat tire situation is effectively increased.

Description

technical field [0001] The invention belongs to the field of transportation vehicles, in particular to a safety device for vehicle tires. Background technique [0002] In order to make the vehicle continue to drive safely and prevent rollover when the tire of the vehicle is blown out, a modern transport vehicle needs to install a tire safety device in the tire. At present, the tire safety device is generally a ring that surrounds the wheel hub. As described in the invention patent named "Tire Safety Device" and the patent number is 201120296934.6, the ring is generally connected by two or three arc-shaped bodies. become. In order to reduce weight and other performance requirements, the ring is mostly made of special engineering plastics; when the vehicle is driving on a rough road section, especially a field gravel road section or a cobblestone road section, or when the vehicle continues to drive after a tire blowout, the tires are safe. Due to the violent impact, the curv...
