CESSNA 172R飞机前轮转弯动作筒为一“半刚性”连接件,其工作原理是飞行员操纵飞机在地面正常滑行或转弯时,一侧的动作筒在脚蹬机构的作用下产生拉力,由于弹簧预紧力大于机轮转弯摩擦力,该动作筒运动如同刚体运动,另一侧的动作筒随动,此时前轮转弯力矩由脚蹬带动动作筒产生,转弯角度为±10°,从而带动前起落架支柱操纵飞机进行转弯。本文主要介绍了在前轮转弯动作筒维护过程中遇到的常见故障、故障分析及经验总结。
CESSNA 172R aircraft front wheel turning cylinder is a “semi-rigid ” connector, the working principle is that the pilot manipulates the aircraft normal taxiing or turning on the ground, the side of the cylinder under the action of the pedal mechanism produces tension due to Spring preload is greater than the wheel turning friction, the movement of the cylinder as rigid body movement, the other side of the cylinder follow the move, this time the front wheel cornering torque generated by the pedal action cylinder, turning angle of ± 10 ° Drive the front landing gear strut to turn the aircraft. This article mainly introduces the common failure, failure analysis and experience summary in the maintenance process of front wheel turning cylinder.
