某新能源车型电动转向泵绝缘故障分析

Analysis and Rectification of Insulation Failure of Steering Pump of a New Energy Vehicle

电动汽车助力转向泵是汽车配件领域中发挥着重要作用的配件之一,对于汽车的转向工作起着极为重要的操控作用,驱动汽车转向轮实现转向功能。在新能源车型中,转向泵工作时受高压驱动,针对新能源车型转向泵常见的绝缘故障,查找原因,并提出整改措施,模拟故障发生的工况,设计试验验证,通过优化设计,解决原设计缺陷,最后成功实施有效的解决方案。

Electric vehicle power steering pump is one of the important parts in the field of auto parts,it plays a very important role in the steering of the car and drives the steering wheel of the car to realize the steering function.In the new energy vehicle,the steering pump is driven by high pressure when it works.In view of the common insulation failure of the steering pump of new energy vehicle,the causes are found and rectification measures are put forward.The working conditions of the failure are simulated and the test is designed and verified.By changing the design,we can solve the original design defects,and finally successfully implement effective solutions.
