摘要
为了解决驻车制动系统人工调整存在的工人劳动强度大、工作效率低、调整结果一致性差等问题,开发了一套基于虚拟仪器的驻车制动自动调整系统。利用虚拟仪器技术实现了对两个伺服电机的控制,协调完成驻车制动系统的调整工作。参照生产线上现用的人工调整流程,对伺服电机的动作流程进行了设计。大伺服电机工作在力矩模式和位置模式下,通过操纵手柄抓持器完成对制动手柄的上抬、下放动作;小伺服电机工作在速度模式下,通过操纵专用套筒完成对拉索调整螺母的预打紧和终打紧。对执行制动手柄上抬和下放动作的关键运动部件进行了设计。对手柄抓持器的强度和寿命进行了计算,计算结果显示手柄抓持器的强度和寿命均满足生产线生产要求。
In order to solve the problems of large labor intensity,low work efficiency and poor consistency of adjustment of the manual adjustment of the parking brake system,a set of automatic adjustment system for parking brake based on virtual instrument was developed.The virtual instrument technology is used to control the two servo motors and accomplish the adjustment of the parking brake system.The servo motor’s action flow was designed according to the present manual adjustment process used on the production line.The large servo motor works in the torque mode and the position mode,and the lifting and lowering action of the brake handle was completed by the handle gripper;the small servo motor works in the speed mode,and the pre-tightening and final tightening of the cable adjustment nut was completed by operating the special sleeve.The key moving parts that perform the lifting and lowering of the brake handle were designed.The strength and life of the designed handle gripper were calculated,which demonstrates that the strength and life of the handle gripper both meet the production requirements of the production line.
