Abstract

The invention belongs to the technical field of tire steering performance detection, and discloses a steering performance detection method of a passenger vehicle radial tire. The steering performancedetection method of the passenger vehicle radial tire comprises the steps that lateral stiffness (A) of the tire is detected; torsional stiffness (B) of the tire is detected; the impression area (C) of the tire is detected; and a steering value (W) of the tire is calculated according to the lateral stiffness (A), the torsional stiffness (B) and the impression area (C), and the steering performanceof the passenger vehicle radial tire is evaluated through the steering value, wherein W=A*0.2+B*0.2+C*0.6. According to the steering performance detection method of the passenger vehicle radial tire,through the computational formula, the steering performance of products can be predicted easily and accurately, the obtained tire steering performance is very close to an actual road test, detectionmethods of all parameters in the steering value computational formula are easy to obtain, prediction and multi-scheme optimization of the steering performance can be completed indoors rapidly at a lowcost, and the cost and time are saved.

Description

technical field [0001] The invention relates to a tire steering performance detection method, in particular to a passenger car radial tire steering performance detection method. Background technique [0002] With the continuous development of my country's economy and society, passenger cars have developed rapidly. As the only part of the car in contact with the road, passenger car radial tires have also developed rapidly. Tires mainly undertake four basic functions in cars: carrying loads and buffering the road. Shock, providing starting acceleration / braking capabilities and providing steering capabilities, among which the steering performance of radial tires for passenger cars is an important part of tire handling performance, which is closely related to daily driving, such as changing lanes, turning, turning, etc. are all affected by steering performance , the main indicators are steering stability and steering response. Good steering performance can effectively improve driv...
