摘要
为了探究电控离合器变速箱的温度变化规律,搭建了基于电控离合器变速箱的电机台架,并进行了电控离合器的温度试验。选取热电偶作为温度传感器,在离合器压盘的表面、离合器盖及飞轮表面处分别选取了测量点记录温度的变化。设计了双滑环结构,将多路旋转的温度信号转换为非旋转可稳定传输的信号。根据稳态工况、动态工况以及起步工况的特点设计了不同的试验方法并进行了台架试验。本试验为建立电控离合器的温度模型提供了具有可行性的试验方案及理论依据。
In order to analyze the temperature characteristic of the E-clutch,an E-clutch experiment bench is established.The temperature is measured by thermocouples,and the temperature measurement points are selected on the surface of the clutch pressure plate,the clutch cover and the flywheel.A dual-slip-ring structure is designed to convert the multiple rotating temperature signals into stable signals.Different methods of experiments are proposed according to steady-state conditions,dynamic conditions,and vehicle starting conditions.The experiments provide available methods and theoretical basis for establishing the temperature model of the E-clutch.
