The invention discloses a deviation rectifying system of a skid type undercarriage. The deviation rectifying system comprises an electronic compass, a differential GPS, a deviation rectifying controlbox and two skid brake actuators. The two skid brake actuators are arranged in two skid base bodies of a skid type undercarriage respectively, each skid brake actuator comprises a brushless motor, a multi-stage speed reducer and a resistance mechanism, and an output shaft of each brushless motor is coaxially and fixedly connected with an input gear of the corresponding multi-stage speed reducer. The resistance mechanism comprises a resistance sliding rail and a resistance bolt, and a rack is arranged on the resistance bolt in the direction of the resistance sliding rail; an output gear of themulti-stage speed reducer is meshed with a rack on the resistance bolt; the deviation rectification control box controls brushless motors of the two skid brake actuators to work according to measurement signals of the electronic compass and the differential GPS. The limited space in the skid is effectively utilized, the problem that deviation rectification of an airplane with a main undercarriagein a skid form is difficult can be effectively solved, braking resistance is increased for braking action under the working condition that deviation rectification is not needed, and the sliding distance is effectively reduced.
本发明公开了一种滑橇式起落架的纠偏系统,包含电子罗盘、差分GPS、纠偏控制盒、两个滑橇刹车作动器;两个滑橇刹车作动器分别设置在滑橇式起落架的两个滑橇基体内,均包含无刷电机、多级减速器和阻力机构,无刷电机的输出轴和多级减速器的输入齿轮同轴固连;阻力机构包含阻力滑轨和阻力插销,阻力插销上沿阻力滑轨方向设有齿条;多级减速器的输出齿轮和阻力插销上的齿条啮合;纠偏控制盒根据电子罗盘、差分GPS的测量信号控制两个滑橇刹车作动器的无刷电机工作。本发明有效利用滑撬内有限的空间,能够有效解决主起落架为滑橇形式的飞机纠偏较为困难的问题,在无需纠偏的工况下增大刹车阻力进行刹车作动,有效减少滑跑距离。
