The invention discloses a high-voltage electric airport tractor with intelligent traction speed regulation. The tractor comprises a whole vehicle controller, a walking electric controller and a driving motor, and further comprises a semi-automatic unhooking mechanism, a traction pin, a rear traction seat structural part, an upper traction force sensing seat, a middle traction force sensing seat and a lower traction force sensing seat, the upper, middle and lower traction force sensing seats are used for respectively collecting traction forces at the upper, middle and lower positions of the traction pin, the whole vehicle controller is used for calculating the whole vehicle traction force according to the traction forces at the three positions, and the whole vehicle controller is further used for acquiring the driving working conditions of the airport tractor and the traction force limit values corresponding to the driving working conditions, judging whether the actually-measured whole vehicle traction force exceeds the traction force set values corresponding to the driving working conditions or not, and if yes, sending a motor speed reduction instruction to the walking electric controller so as to limit the increase of the traction force. Real-time monitoring and intelligent speed regulation of traction force are achieved, the working state of the whole machine is accurately matched, and invalid power loss and faults are reduced.

    本发明公开了一种智能牵引调速的高压电动机场牵引车,包括整车控制器、行走电控、以及驱动电机,还包括半自动脱钩机构、牵引销、后牵引座结构件、上牵引力感应座、中牵引力感应座、下牵引力感应座,其中,所述上中下牵引力感应座用于各自采集牵引销上中下三个位置的牵引力,所述整车控制器用于根据三个位置的牵引力来计算整车牵引力,所述整车控制器还用于获知机场牵引车的行驶工况、各行驶工况下对应的牵引力限定值、并判断实测的整车牵引力是否超出该行驶工况下对应的牵引力设定值,若超出则向行走电控发送电机减速指令,以限制牵引力的提升。本发明实现了牵引力的实时监测和智能调速,精准匹配整机工作状态,降低无效功率耗损和故障的发生。
