Problems solved by technology

[0002] Tire uniformity refers to the unevenness of the tire circumferential force fluctuation characteristics when the tire is subjected to radial load and rotates at high speed. Uniformity, uneven size and shape, and errors in assembly dimensions cause the tires to produce alternating and fluctuating radial and lateral forces, which cause the car's up and down vibration, left and right deviation, noise, etc., affecting the car's handling, Comfort or stability, serious damage to auto parts, and even cause traffic accidents

Abstract

The invention relates to a detection device for an acting force between an automobile tyre and a load wheel. The detection device comprises a load wheel, a sensor and a sensing system signal processor. The load wheel is close to a tyre as a driven wheel of the tyre. The sensor collects a radial force and lateral force between the load wheel and the tested tyre and sends the collected forces to the sensing system signal processor. The sensor comprises an X-direction differential capacitive unit group and a Y-direction differential capacitive unit group. The X-direction differential capacitive unit group and the Y-direction differential capacitive unit group comprise more than two capacitive unit modules forming differential action respectively. Each capacitive unit module has a comb-shaped structure composed of more than two strip-shaped capacitive units. The detection device measures the radial force and the lateral force between the tyre and the load wheel, through the two parameters, analysis of parameters of radial force fluctuation, lateral force fluctuation, conicity, sideslip, radial deviation, lateral deviation and the like is carried out. Nonuniformity of the tyre is calibrated scientifically.

Description

technical field [0001] The invention belongs to the technical field of automobile equipment detection, and in particular relates to a detection device for the force between automobile tires and load wheels. Background technique [0002] Tire uniformity refers to the unevenness of the tire circumferential force fluctuation characteristics when the tire is subjected to radial load and rotates at high speed. Uniformity, uneven size and shape, and errors in assembly dimensions cause the tires to produce alternating and fluctuating radial and lateral forces, which cause the car's up and down vibration, left and right deviation, noise, etc., affecting the car's handling, Comfort or stability, serious damage to auto parts, and even cause traffic accidents. [0003] By measuring the radial force and lateral force obtained by the tire uniformity detection device, analyze the radial force fluctuation, lateral force fluctuation, taper, running deviation, radial deviation (top, center,...
