摘要

湿式离合器是装甲车辆动力换挡的关键部件，随着综合传动系统转速和功率密度的提高，接合特性与摩擦副过度磨损、局部烧损、钢片翘曲等失效问题密切相关。针对湿式离合器的接合过程，设计并搭建了多模式加载试验台，采用机械惯量、电涡流测功机及制动装置作为负载模拟装置，针对不同转速和控制油压下的湿式离合器接合特性开展了试验研究。通过制动装置固定从动端，改变不同的滑摩转速和控制油压，测得对应的稳定滑摩转矩，推导出相应的动静摩擦因数。研究有助于进一步掌握该型湿式离合器的传动特性，评估其服役性能。

Abstract

The wet clutch is a key power shift component of the armored vehicle. With the increase of the speed and power density of the integrated transmission system， the engagement characteristics are closely related to the failure problems such as excessive wear of the friction pair， partial burning， and warpage of the steel sheet. For the engagement process of the wet clutch， a multi-mode loading test rig is designed and built. The mechanical inertia， eddy current dynamometer and braking device are used as the load simulation device. The engagement characteristics test of wet clutch for different speeds and control oil pressure are carried out. The corresponding stable sliding friction torque with different sliding speed and control oil pressure is measured when the load end by braking device is fixed. The corresponding dynamic and static friction coefficients are derived， which will help to further obtain the transmission characteristics of the clutch and evaluate for its service performance.
