摘要:
换段品质研究一直是车辆传动系统研究与开发的重要内容.以由液压机械无级变速器和液压机械差速转向机构组成的履带车辆综合传动系统为研究对象,通过对换段品质评价指标的理论分析,结合农业履带车辆的工作特点,提出了采用动载系数和换段时间作为换段品质试验的评价指标.搭建了由LR6105ZT10型柴油发动机作为驱动系统、由CW150型电涡流测功机和自制电液比例控制盘式制动器作为负载模拟系统、由工控机作为主要测控系统的试验台,建立了发动机及系统负载的计算模型,采用转向负载系数表达车辆综合传动系统两侧负载的变化关系,给出了发动机的控制方法及系统负载在试验台上的实现方法.以F4段换入F5段为例,对履带车辆转向工况综合传动系统换段品质进行了试验研究.
Abstract:
The shift quality is always the important research and development content of variable transmission sys-tem for vehicle.With the research object being integrated transmission system of tracked vehicle composed ofhydro-mechanical continuously variable transmission and hydro-mechanic differential turning mechanism,after an a-nalysis of the evaluating indicators of shift quality,and in consideration of the working characteristic of farm trackedvehicle,it is put forward that the dynamic load coefficient and shift time are as the evaluating indicators of shiftquality test.The test bench is made up of driving system,measured system,load simulation system and observingand controlling system etc.The LR6105ZT10 diesel engine acts as driving system.The CW150 electric eddy currentdynamometer electro-hydraulic proportional control disc brake act as the load simulation system.The observing andcontrolling system is mainly made up of industrial control computers. The calculation models of engine and load ofintegrated transmission system are established.The turning load coefficient is adopted to express the two side loadchange relationship of integrated transmission system of tracked vehicle. The controlling method of engine and reali-zing method of load on test bench are given. As the example for F4 switching F5,the test research of shift processof tracked vehicle based on integrated transmission in turning conditions was carried out.
