Problems solved by technology

At present, the detection of steering gear performance is manual detection. During the detection process, when a parameter is detected, repeated detection is required to reduce the measurement deviation in the manual detection process, thereby ensuring the accuracy of the detection results. The detection of parameters is not only labor-intensive but also low in efficiency; at the same time, due to individual differences, the detection results often have large errors and are not accurate enough

Abstract

The invention relates to an automobile steering device performance detection method and a detection machine, which belong to the field of automobile steering device performance detection. According tothe detection method, various performances of a workpiece are parametrically detected and evaluated through preparation, meshing clearance and axial force detection and evaluation, bushing clearancedetection and evaluation and no-load torque detection and evaluation effects; manual repeated detection is not needed; the accuracy of a detection result can be ensured, and the labor intensity can beeffectively reduced; the working efficiency is improved; and the problems of high labor intensity, low working efficiency and measurement deviation of the detection result due to repeated detection in the current manual detection process are solved.

Description

technical field [0001] The invention relates to a method for detecting the performance of an automobile steering gear and a detection machine, belonging to the field of performance detection of an automobile steering gear. Background technique [0002] Automobile steering gear is an important part of the automobile steering system. It is installed between the steering wheel and the steering rocker arm. Its function is to amplify the torque acting on the steering wheel to save effort and ensure the flexibility of steering operation. The performance of the steering gear is comprehensively considered from the three factors of labor-saving operation, automatic steering return and transmission of appropriate road feel. The heavy steering, poor automatic return and abnormal noise of the steering gear during the use of most cars are mainly related to the performance parameters of the product before installation. Unqualified, such as the steering gear rack moving force is too large ...
