Multifunctional road detection device and test method for tires

Abstract

The invention relates to a multifunctional road detection device and a test method for tires. Two suspension systems and two tire steering mechanisms of the multifunctional road detection device are arranged on a frame and are respectively independently connected with the tested tires on two sides of the multifunctional road detection device, so that the tires can be independently steered and can be adjusted in internally gathered or externally scattered states, and lateral inclination angles of the tires can be adjusted. The multifunctional road detection device and the test method have the advantages that data of rotation angles, lateral force, longitudinal acceleration, lateral acceleration and the like of the tires can be acquired by various relevant sensors during driving, so that mechanical properties of the tires under on-site road conditions can be detected; the problem of difficulty in simulating actual service road surfaces by existing indoor detection devices for tires and problems of unbalanced force under lateral deviation and lateral rolling working conditions and single detection working conditions of existing outdoor detection devices for the tires can be solved; the multifunctional road detection device is simple in structure and easy to control and adjust.

Description

technical field [0001] The invention relates to a detection device suitable for obtaining tire characteristics under outdoor road conditions and a tire characteristic testing method based on the device. Background technique [0002] Tires are the only components between the vehicle and the road, and the interaction of the tires with the road determines the vehicle's motion. Many important performances of a vehicle are related to the properties of the tires. Vehicle handling stability, braking safety, vehicle vertical vibration, and vehicle dynamics all depend on the study of tire characteristics. Therefore, the study of tire characteristics has great practical significance and broad application prospects. [0003] However, the physical structure of the tire and the friction characteristics between the tire rubber and various road surfaces are very complicated. It is not only related to speed and vertical pressure, but also affected by the type of road surface and the road ...
