摘要
电动汽车传动系统与驱动系统作为核心动力总成,其运行稳定性直接影响车辆行驶安全与使用效能。本文结合工程实践,阐述传动系统单级减速器功能及驱动系统永磁同步电机工作原理,分析两类系统常见故障及成因,对比传统与现代智能诊断技术的差异,重点研究传感器实时监控、车载-云端数据故障预测技术,结合远程在线诊断、AR辅助维修、预测性维护协同构建维修体系,为提升动力系统维修效率、降低成本提供支撑。
As the core powertrain,the operational stability of electric vehicle transmission and drive systems directly determines driving safety and efficiency.Based on engineering practice,this paper expounds the function of single-stage reducer in transmission system and the working principle of permanent magnet synchronous motor(PMSM)in drive system,analyzes common faults and causes of the two systems,compares the differences between traditional and modern intelligent diagnostic technologies,focuses on sensor-based real-time monitoring and vehicle-cloud data fault prediction technologies,and constructs a maintenance system by integrating remote online diagnosis,augmented reality(AR)-assisted maintenance and predictive maintenance,so as to provide technical support for improving the maintenance efficiency of power systems and reducing costs.
