specific Embodiment 1

[0029] The detonating device in the tire of the tire blowout performance test based on circular motion of the present embodiment comprises a spherical housing 1, an detonating device arranged in the spherical housing 1, and three sets of permanent magnets 3 symmetrically arranged outside the spherical housing 1 for fixing the permanent magnets. The frame 4 of the magnet 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;

specific Embodiment 2

[0037] The tire blowout performance test device in this embodiment based on circular motion, on the basis of the specific embodiment 1, further defines that there is a rotating disc 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 disc 57 , the other side of the turntable 57 is installed with a screw 58 parallel to the turntable 57, the screw 58 is provided with a nut 59, 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] The circular motion-based tire blowout performance testing device in this embodiment further defines that the rotating shaft 51 and / or the connecting rod 52 can move along its direction on the basis of the specific embodiment 1 or the specific embodiment 2.

[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 provides a circumferential motion mechanism of a tyre internal detonating device for the tyre burst performance test, and belongs to the technical field of automobile spare parts. The mechanism comprises a rotating shaft coaxial with the tyre symmetry axis and a connecting rod parallel to the rotating shaft. One end of the rotating shaft is connected with a motor through a coupler, and the other end is connected with the fixed end through a bearing. The rotating shaft is fixedly connected with the inner ring of the bearing. The fixed end is fixedly connected with the outer ring of the bearing. The connecting rod is coaxial with the straight line on which a group of permanent magnets are located. The middle part of the connecting rod is provided with a frame. The distance between the rotating shaft and the connecting rod can be adjusted. A rotating disc is included between the rotating shaft and the connecting rod. The rotating shaft is fixedly connected to the center of one side of the rotating disc. The other side of the rotating disc is provided with a screw rod parallel to the rotating disc. A screw cap is arranged on the screw rod, and the screw cap is fixedly connected with the connecting rod. The circumferential motion mechanism is applied to the tyre internal detonating device for the tyre burst performance test so as to lay the experimental foundation forthe 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 circular motion mechanism for a tire internal explosion device used for tire burst performance testing, which belongs to the technical field of auto parts. 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 blowou...
