【摘要】 根据电动重型货车的整车参数及动力性能需求,设计了一款两挡电驱动桥,并分析了该电驱动桥的润滑特性。根据CHTC-HT工况最高车速设置输入轴转速,再根据传动比设置中间轴、输出轴转速,利用SPH方法结合PreonLab软件对其在不同润滑油油量下的润滑效果和搅油损失进行了分析。结果表明:电驱动桥设计合理,润滑效果良好;随着润滑油液面高度的增加,系统的搅油损失功率不断增加,各齿轮、轴承的润滑效果有一定的提升。更多还原

【Abstract】 Based on the complete vehicle parameters and power performance requirements of the heavy-duty truck,a two-speed electric drive axle was designed,and the lubrication characteristics of the electric drive axle were analyzed.The input shaft speed was set according to the highest vehicle speed under CHTC-HT working conditions,and then the intermediate shaft and output shaft speeds were set based on the transmission ratio.The lubrication effect and agitation loss under different lubricating oil quantities were analyzed using the SPH method combined with PreonLab software.The results show that the design of the electric drive axle is reasonable,and the lubrication effect is good.With the increase of the lubricating oil level,the agitation loss power of the system continues to increase,and the lubrication effect of each gear and bearing also improves to a certain extent.更多还原
