The invention discloses a measuring toll and a measuring method of FSAE racing car wheel and frame positioning angles. The measuring tool comprises two sets of wheel positioning devices and two sets of frame positioning devices, each wheel positioning device comprises a column, a rotation beam movably connected at the upper end of the column, and a rim clamp arranged at an end part of the rotation bream, and the rim clamp can rotate relative to the rotation beam. An included angle between two camber angle measuring planes of each wheel positioning device is measured via a universal bevel protractor to indirectly obtain a wheel camber angle, and the included angle between a toe-in angle measuring plane of the wheel positioning device and a toe-in angle measuring plane of the frame positioning device is measured via the universal bevel protractor to indirectly obtain a wheel toe-in angle. According to the measuring tool and the measuring method, compared with the conventional measuring tool and the measuring method of the FASE racing car wheel positioning angle, the installation and the usage of the tool are convenient, the measuring method is simple and reasonable, and more visual and accurate measuring data of the wheel positioning angle is provided for technical personnel of a vehicle team.
Description
technical field [0001] The invention relates to the measurement of a mechanical structure, in particular to a measuring tool and a measuring method for an FSAE racing car wheel and a vehicle frame positioning angle. Background technique [0002] The driving comfort, safety, handling stability and tire wear and condition depend largely on the movement characteristics of the chassis. In recent years, automakers have been reinventing old designs in order to bring better-performing, more refined models to the market. In order to meet a more ideal chassis kinematics design, more adjustment points are set on the vehicle suspension, so there are stricter requirements for the vehicle wheel alignment measurement. For example, Mercedes-Benz, BMW and other toe angle tolerance requirements have reached 2 points. In order to keep up with the development of automotive technology, more sophisticated optical and electronic measurement systems have emerged as the times require. The new ge...
