Problems solved by technology

[0004] The above-mentioned parameters that form and affect tire uniformity are direct factors for measuring and judging tire design and production quality, but there is a considerable one-sidedness in the existing tire testing process due to the lack of systematic theoretical support and complete implementation methods and error

Embodiment 1

[0052] In Example 1, the tire uniformity measurement method uses the tire uniformity test device shown in FIG. 1. Wherein, the housing of the main shaft 1 does not rotate and has a supporting point, so that the main shaft 1 is in a suspended and semi-free state.

[0053] In the process of tire uniformity measurement, the spindle 1 will vibrate slightly, the sensor 6 is close to the outer shell of the spindle 1, and the sensor 6 will detect the vibration of the spindle.

[0054] Except for the main shaft part of the housing, the upper rim 3 can be rotated freely. The upper and lower rims are used to simulate the hub of the wheel, and play the role of clamping the tire and preventing the tire from deflating after inflation.

[0055] The axis of the load wheel 5 is always parallel to the axis of the main shaft 1, the material of the load wheel 5 is uniform, the geometric shape is symmetrical, and it can move horizontally to the left and right.

[0056] In the test, the load wheel 5 s...

Abstract

The invention relates to a measuring method of the uniformity of a tire. The invention aims at solving the problem and building a parameter to affect the uniformity of the tire, the parameter is measured though a uniformity measuring device, and integrated judgment is acquired and the degree is set according to an actual measured parameter value, and analysis and theorem reference can be formed with pertinence, the productive quality of the tire can be improved, and the restitute ratio can be reduced.

Description

Technical field [0001] The invention relates to a tire uniformity measurement method, in particular to determine the tire uniformity level by measuring specific values ​​forming and affecting uniformity parameters, and belongs to the field of tire quality inspection. Background technique [0002] Tires are the main action-executing components of motor vehicles. The stability of tire performance and compliance with safety design standards will directly determine the safety of personnel using motor vehicles. The tire is a circular ring-shaped rotatable body with a cylindrical section, which is formed by laminating, forming, vulcanizing and shaping multiple layers of rubber prefabricated materials with steel cords and composite rubber prefabricated materials. The tires with the above-mentioned structure inevitably have problems such as uneven density and geometric deformation in their constituent materials, that is, the tires are often said to be uneven. According to the relevant me...
