摘要
为了方便煤矿铰接式运输车辆设计,需要对液力机械传动系统的变速箱设计开发,阐述了某型定轴式动力换挡变速箱档位数及换挡操纵设计、各档位传动比确定、输入与输出中心距确定、换挡和换向离合器设计、各档位离合器的组合方式、结构设计等关键技术。变速箱台架试验传动效率范围96.3%~98.5%,传动油最大温度为88.5℃;变速箱装车使用平均维修周期为8个月,全寿命成本与进口件相当,可替代进口。通过改变变速箱各档位传动比,系列化设计的定轴式动力换挡变速箱能应用于不同载荷的铰接式运输车辆,解决了无轨辅助运输车辆关键元部件及核心技术长期依赖进口的问题。
In order to facilitate the design of articulated transport vehicles in coal mines,gearboxes for hydro-mechanical transmission systems need to be developed.The key technologies of the design of number of gears and shift control of a certain fixed-shaft power shift transmission,the determination of the transmission ratio of each gear,the determination of the center distance between the input and output,the design of the shift and reverse clutch,combination mode of each gear clutch and the design of the structure are described.Transmission bench test transmission efficiency ranges from 96.3%to 98.5%,and the maximum temperature of transmission oil is 88.5℃.The average maintenance cycle of gearbox loading is 8 months,and the full life cost is equivalent to imported parts,which can replace imported ones.By changing the transmission ratio of each gear,series design of fixed shaft power shift gearbox can be used for articulated transport vehicles with different loads,it can change the situation that the key technology and components of trackless auxiliary transport vehicle relies on import for a long time in the past.
