Embodiment Construction

[0049] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0050] Such as figure 2 Shown is a working flow chart of a method for detecting the included angle of a front suspension assembly according to the present invention. The front suspension assembly includes a brake disc and a shock absorber strut arranged on the brake disc. The shock absorber strut The angle between the plane of the brake disc and the brake disc where the brake disc is located is the angle of the front suspension assembly, and the detection method for the angle of the front suspension assembly includes:

[0051] Step S201, controlling the position sensor to take a plurality of measuring points on the brake disc of the front suspension assembly, and obtaining the spatial coordinates of each measuring point in the preset spatial coordinate system;

[0052] Step S202, taking a picture of the upper end of the shock absorb...

Abstract

The invention discloses a method for detecting the included angle of a front suspension assembly and electronic equipment. The method includes: controlling a position sensor to take a plurality of measuring points on the brake disc of the front suspension assembly, and obtaining each measuring point in a preset space coordinate system The spatial coordinates of the shock-absorbing strut; the upper end of the shock-absorbing strut is photographed to obtain the photo of the upper end of the shock-absorbing strut; Space coordinates in the coordinate system; in the space coordinate system, fit multiple measuring points into a plane, connect the center point of the upper end of the shock-absorbing strut and the center point of the lower end of the shock-absorbing strut to make a straight line, and calculate the distance between the line and the plane The included angle is used as the included angle of the front suspension assembly. The invention is convenient and quick to operate, has low technical requirements for operators, and can realize mass detection of the included angle of the front overhang.

Description

technical field [0001] The invention relates to the technical field related to automobiles, in particular to a method for detecting the included angle of a front suspension assembly and electronic equipment. Background technique [0002] The front suspension assembly is an assembly assembly of shock absorbing struts, steering knuckles, brake discs and other parts. Such as figure 1 As shown, there is an included angle 5 between the axis 2 of the shock absorbing strut 1 and the brake disc plane 4 of the brake disc 3 , and this included angle will be referred to as the included angle of the front suspension assembly hereinafter. Due to the position tolerance of the assembly holes on the shock absorber, steering knuckle and other parts, it will cause the fluctuation of the included angle of the front suspension. The included angle of the front suspension assembly will directly affect the wheel camber. In order to ensure that the wheel camber is within the ideal range, the inc...
