Abstract

The invention discloses a detecting method and device for the distance between leaf spring eyes, and belongs to the automobile field, particularly automobile suspensions. The detecting method comprises the following steps that the radius r of each spring eye of a leaf spring assembly, the arc length l between the points of contact of the two spring eyes of the leaf spring assembly and the arc face of the leaf spring assembly and the arc height f of the leaf spring assembly are obtained; the curvature radius R of the arc face of the leaf spring assembly is iteratively calculated based on the radius r of each spring eye, the arc length l, the arc height f and a preset original curvature radius value of the leaf spring assembly; and the distance S0 between the centers of the spring eyes of the leaf spring assembly is calculated based on the curvature radius R, the radius r of each spring eye and the arc length l. The detecting method and device can precisely detect the distance between the centers of the leaf spring eyes.

Description

technical field [0001] The present disclosure relates to the field of automobiles, in particular to the field of automobile suspensions, and in particular to a method and device for detecting distance between lugs of leaf springs. Background technique [0002] In the field of automobile suspension, leaf spring suspension is widely used. Since the leaf spring is a deformed part, to calculate the exact position of the leaf spring, it is necessary to calculate the distance between the ears of the leaf spring assembly at different arc heights of the leaf spring assembly. [0003] The commonly used method of detecting the distance between the lugs of leaf springs is to detect through the corresponding original calculation formula under the two-dimensional design software. The formula is as follows: [0004] [0005] The accuracy of this detection method is relatively poor. Contents of the invention [0006] The purpose of the present disclosure is to provide a method and d...
