Inclination detection device and method for tire durability

Abstract

The invention relates to an inclination detection device and a method for tire durability, and provides an additional inclination detection device and a technical method of specifically improving a tire wear tracking and detecting means. The detection method for high speed/durability of a tire inclined in running is added mainly based on simulation of mounting inclination of the tire, and road conditions such as surface inclination, unevenness and the like. The detection device mainly comprises a frame, a drum driven by an electric motor to rotate around a fixed axis and simulate a pavement for running is disposed on the frame, a hydraulic pressing device and a movable seat are disposed on two lateral stations of the drum, an arc horizontal guide rail and a perpendicularly fixed swing shaft are disposed on a base, a swing seat is mounted between the base and the movable seat, the bottom of the swing seat is slidably connected to the horizontal guide rail, one end corner of the swing seat is sleeved to the swing shaft, an inclination drive hydraulic cylinder which drives the swing seat to incline on the horizontal guide rail and by centering on the swing shaft is disposed between the base and the swing seat.

Description

technical field [0001] The present invention relates to a device and method for rubber tire high-speed / durability performance experiments, and in particular provides a detection device and its detection process for simulating a certain inclination angle when the tire is installed or driving on an uneven road surface with an inclination angle The method belongs to the field of rubber machinery and automatic production control. Background technique [0002] With the increase of domestic automobile penetration rate and the increasing urban traffic congestion, the stability and safety of high-speed driving have become the core reference data for measuring the quality of tire design and production. In order to accurately detect the safety of tires under high-speed or long-term use, it is usually necessary to carry out high-speed / durability performance testing in the production process. [0003] Based on the continuous innovation of current manufacturing technology, the tire high...

AI Technical Summary

Problems solved by technology

[0004] The existing tire high-speed / durability testing machine has a smooth drum, no obstacles, and fixed-axis rotation. The tire installation is tangent to the drum surface without relative inclination and torque, so it can only simulate the tire running in a straight line on a flat surface. Durability on the road surface, but the specific conditions when the vehicle is driving is that the vehicle is turning, non-straight driving, or the tire is installed on the axle at a certain angle, the road surface is inclined and the surface is uneven, so most of the above facts are missing. The road shape performance test is not targeted, and the test data cannot truly reflect the actual use needs of the tire, which is not conducive to feedback and improvement of tire production quality, and the design quality needs to be further improved
