Abstract

The invention provides a method for evaluating the performance of a front axle in a loading state. The related detection equipment comprises a gantry bracket, a front axle assembly, a capacitive grating type dial indicator, a front axle fixing bracket, a steel ring, a toe-in measuring instrument, a rotating disc, a servo hydraulic cylinder and the like and is characterized in that the front shaft fixing support is connected with the gantry support and used for fixing a front shaft, and the front shaft is kept stable in the test process; the toe-in measuring instrument is composed of a stay wire sensor and a gradienter and used for accurately measuring the toe-in value of a front axle and outputting toe-in information in real time. The servo hydraulic cylinder can load the front axle according to test requirements and output loading information in real time. The capacitive dial indicator can measure and output the deformation of each key position of the front axle in real time, and the comprehensive performance of the front axle can be evaluated.

Description

technical field

[0001] The invention relates to a performance evaluation device and method in a loaded state of a front axle, belonging to the technical field of front axles of commercial vehicles. Background technique

[0002] The toe-in of the front wheel is to eliminate the adverse consequences caused by the wheel camber. It is a very important performance parameter for vehicles, especially for commercial vehicles; the stiffness of the front axle is also very important, and it also affects the toe-in of the front wheels and the whole vehicle performance. At present, the measurement of front axle parameter performance in the industry is mainly static measurement or discontinuous measurement, which cannot completely simulate the performance of the front axle under various loads. Contents of the invention

[0003] The object of the present invention is to provide a performance evaluation device and method under the loading state of the front axle, which can dynamically me...
