为了进一步减少混合动力车辆湿式多片离合器摩擦过热现象并延长其使用寿命,以混合动力车辆湿式多片离合器为研究对象,建立湿式离合器摩擦副接合工况下瞬态传热模型,将湿式离合器摩擦盘径向矩形油槽宽度设置为分析变量,得到矩形油槽宽度对摩擦盘瞬态温度场的影响。研究结果表明,随着摩擦盘径向矩形油槽宽度的增加,湿式离合器最高温度将呈现下降趋势,但在角度范围内摩擦盘温度与摩擦盘几何特征存在较大的关联性,呈现一定的周期特性;径向矩形油槽宽度对湿式离合器温度场的影响进行了定性研究,为后续通过优化设计方法得到最佳矩形油槽宽度指明了方向。
In order to further reduce the friction overheating and prolong the service life of wet multi-plate clutches in hybrid vehicles, the wet multi-plate clutch of hybrid vehicle is taken as the research object to establish the transient heat transfer model under wet clutch friction pair engagement condition. The wet clutch friction The width of the rectangular radial groove was set as an analysis variable, and the influence of rectangular groove width on the transient temperature field of the friction plate was obtained. The results show that the maximum temperature of the wet clutch will decrease with the increase of the radial groove width of the friction disc. However, there is a large correlation between the temperature of the friction disc and the geometrical characteristics of the friction disc in the angle range, showing some periodic characteristics ; Radial rectangular groove width of the wet clutch temperature field qualitative research conducted for the follow-up to optimize the design method to get the best rectangular tank width pointed out the direction.
