The present invention relates to the technical field of toe measurement, and discloses a method for measuring toe of a commercial vehicle, comprising the steps of: S1: drawing equal heights on the tread and sidewall at the front end of each steering wheel and on the tread and sidewall at the rear end line, the contour lines of the two steering wheels are located at the same height; S2: attach a square to one of the contour lines, the handle of the square is attached to the sidewall, The scale portion of the square fits the tread; S3: Select a scale of the scale portion of the square as a reference scale, and the position corresponding to the reference scale on the contour line is set as a reference position; The reference positions of the front end and rear end of the steering wheel are point A and point C respectively, and the reference positions of the front end and rear end of the other steering wheel are point B and point D respectively; S4: wheel alignment; S5: vehicle The toe-in value is CD‑AB. The invention can quickly, easily and accurately realize the measurement of the toe-in of the vehicle.
Description
Technical field [0001] The present invention relates to the field of front beam measurement, and more particularly to a commercial vehicle front beam measurement method. Background technique [0002] For commercial vehicles, the steering wheel has a variety of positioning parameters: such as the front beam, vehicle outer hiring angle, the main pin pinner, the main pin angle, etc., the above positioning parameters are important parameters to ensure wheel stable driving, if positioning parameters A deviation, the vehicle will have an abnormal wear and running bias, reduce the life of the tire, and the control of the vehicle also varies. [0003] The front bunch refers to the difference between the vehicle in the driving state, the two steering wheel distances and the distal end distance; due to the adjustment of the front beam value, the front beam value is also the main factor affecting the abnormal wear of the steering wheel tire, Therefore, the front beam measurement is critical...
