Abstract

The present disclosure relates to a wheel alignment calibration device and a wheel alignment calibration system. The wheel alignment calibration device comprises a first measurement tool and a second measurement tool. The first measuring tool comprises two measuring tools which are respectively arranged on rims of vehicles to be measured and used for installing first sensors, and the second measuring tool comprises two measuring tools which are respectively arranged on the front side and the rear side of the wheels of the vehicles to be measured and used for installing second sensors, wherein the second measuring tools are configured to be capable of adjusting the positions of the second sensors in the vehicle width direction and the height direction. Through the technical scheme, the first sensor and the second sensor can be mutually matched into the transmitter and the receiver, so that the total toe-in value of the wheel and the toe-out dividing value of the wheel are obtained. In the measuring process, the position orientation of the vehicle body and whether the traveling wheels and the guide wheels are in the zero position or not do not influence the measurement of the total toe-in value and the toe-out value, and the measuring process is simple and has higher efficiency.
