specific Embodiment 1

[0029] The tire internal detonating device that is used for tire blowout performance test of the present embodiment comprises spherical shell 1, is arranged on the detonating device in spherical shell 1, three groups of permanent magnets 3 that are symmetrically arranged on spherical shell 1 outside, are used for fixing permanent magnet The frame 4 of 3 is used to control the circular motion mechanism of the frame 4 movement; the spherical shell 1 is arranged inside the tire, and the permanent magnet 3, the frame 4 and the circular motion mechanism are arranged outside the tire;

[0030] Among them, the position and structural relationship between the spherical shell 1, the three groups of permanent magnets 3 and the frame 4 are as follows figure 1 shown;

[0031] The spherical shell 1 is a hollow spherical magnet with ventilation holes, the positive hemisphere is the N pole, and the negative hemisphere is the S pole;

[0032] Described detonating device comprises wireless re...

specific Embodiment 2

[0037] The tire internal detonation device for tire blowout performance test of this embodiment, on the basis of the specific embodiment 1, further defines that there is a rotating disk 57 between the rotating shaft 51 and the connecting rod 52, and the rotating shaft 51 is fixedly connected to the center of one side of the rotating disk 57, A screw 58 parallel to the turntable 57 is installed on the other side of the turntable 57 , a nut 59 is arranged on the screw 58 , and the nut 59 is fixedly connected with the connecting rod 52 .

[0038] The position and structural schematic diagram between rotating shaft 51, connecting rod 52, rotating disk 57, screw rod 58 and nut 59 are as Figure 4 shown.

[0039] This structural limitation provides a specific mechanical structure for realizing the adjustable distance between the rotating shaft 51 and the connecting rod 52 .

specific Embodiment 3

[0040] On the basis of the specific embodiment 1 or the specific embodiment 2, the tire internal detonation device for tire blowout performance test of this embodiment further defines that the rotating shaft 51 and / or the connecting rod 52 can move along its direction.

[0041] This structural limitation enables the detonating device of the present invention not only to determine the position within the circumferential surface, but also to adjust the position in the direction perpendicular to the circumferential surface, which enriches the explosion points and facilitates the acquisition of more experimental data.

Abstract

The invention relates to a tyre internal detonating device for the tyre burst performance test, and belongs to the technical field of the automobile performance test. The detonating device comprises aspherical shell, a detonating device which is arranged in the spherical shell, three groups of permanent magnets which are symmetrically arranged outside the spherical shell, a frame which is used for fixing the permanent magnets and a circumferential motion mechanism which is used for controlling the motion of the frame. The spherical shell is arranged inside the tyre. The permanent magnets, theframe and the circumferential motion mechanism are arranged outside the tyre. The detonating device does not affect the rotational performance of the tyre and can provide the technical means for tyrebursting at the accurate position so as to lay an experimental foundation for the development of the performance test device after tyre bursting.

Description

[0001] This application is a divisional application of the invention patent application "A Tire Inner Detonation Device Based on Circular Motion-Based Tire Blowout Performance Test". [0002] The original filing date: 2016-12-05. [0003] Original application number: 2016111007662. [0004] Invention name of the original application: a tire internal detonation device for tire burst performance testing based on circular motion. technical field [0005] The utility model relates to a tire internal detonation device used for tire burst performance testing, which belongs to the technical field of automobile performance testing. Background technique [0006] A puncture refers to a tire that suddenly loses air due to rupture and deflates in a very short period of less than 0.1 second. Tire blowout is one of the frequent accidents of automobiles in summer. Relevant statistics show that 10% of traffic accidents on expressways are caused by tire failures, and tire blowouts account ...
