The invention discloses a front axle assembly with a steering angle measuring mechanism, which comprises a front beam, a steering knuckle, a master pin and a steering angle sensor, the master pin is respectively connected with the steering knuckle and the front beam, the steering knuckle is provided with a master pin upper connecting hole and a master pin lower connecting hole, the front beam is provided with a front beam pin hole, a thrust bearing is arranged on the master pin lower connecting hole at the lower part of the front beam, and the steering angle sensor is arranged on the front beam. A kingpin upper connecting hole of the steering knuckle is connected with the upper portion of the kingpin, a thrust bearing and a kingpin lower connecting hole are connected with the lower portion of the front beam, the steering angle sensor comprises the upper portion of the steering angle sensor and the lower portion of the steering angle sensor, the upper portion of the steering angle sensor is connected with the steering knuckle, and the lower portion of the steering angle sensor is connected with the kingpin. The relative rotation angle of the steering knuckle and the main pin can be directly measured, accurate measurement of the steering angle is achieved, and the accuracy of the measured angle is effectively guaranteed. The system has the advantages of accurate information acquisition and high feedback precision, and is particularly suitable for the development requirements of the commercial vehicle automatic driving technology.
