Front axle assembly with steering angle measuring mechanism

Abstract

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.

Description

Technical field [0001] The present invention relates to a steering angle measuring mechanism, in particular to a front axle assembly with a steering angle measuring mechanism. Background [0002] At present, with the development of commercial vehicle autonomous driving technology, vehicles have higher and higher requirements for accurate information collection and feedback accuracy, especially for steering systems. Most of the existing steering angle measurements are used as steering angle input through the steering wheel angle, and the input of the steering wheel angle is affected by the various components of the entire steering system and its assembly error, the accuracy is not high, coupled with the development of automatic driving technology and the real landing of subsequent technologies, the steering wheel will gradually weaken or even cancel. There is therefore an urgent need to develop new and precise steering angle measuring mechanisms based on existing structures. Cont...

AI Technical Summary

Problems solved by technology

It solves the problem that the existing steering system components and assembly errors of commercial vehicles in the prior art are relatively large due to the rotation angle of the front steering axle passing the rotation angle of the steering wheel as the input source of the steering angle, and the problem that the accuracy of the actual steering angle cannot be truly and effectively reflected
