Abstract

The present application relates to the technical field of vehicles, in particular to a vehicle wheel center measuring device and method. The vehicle wheel center measurement device includes: a mounting base, a height adjustment structure and a first laser pointer, a second laser pointer, an intermediate laser pointer and a displacement structure installed on the mounting base, wherein the first laser pointer, The second laser pointer and the middle laser pointer respectively have a first laser emitting end whose emission direction is perpendicular to the installation base, and the first laser pointer and the second laser pointer are arranged symmetrically on the middle laser pointer On both sides, the displacement structure is used to control the equidistant displacement of the first laser pointer and the second laser pointer in opposite directions along the line connecting the centers of the first laser pointer and the second laser pointer, so The height adjustment structure is used to adjust the height of the installation base. The vehicle measuring device has the advantages of simple structure, convenient and quick measurement, and high measurement accuracy.

Description

technical field [0001] The present application relates to the field of vehicle technology, in particular to a vehicle wheel center measurement device and measurement method. Background technique [0002] For a model, after defining the vehicle coordinate system, the body coordinates are fixed. In order to characterize the state of the vehicle under different load conditions, the vehicle attitude is generally used in the industry to describe the design relationship between the vehicle and the ground. At the same time, the posture of the vehicle will also affect the aesthetics of the vehicle. Therefore, the vehicle attitude is a very important parameter in the process of vehicle design verification. Generally, the attitude of the vehicle is characterized by parameters such as wheel center coordinates, static radius, and attitude angle. [0003] At present, when measuring the wheel center of a vehicle, the industry generally obtains the position of the wheel center by scanni...
