Discussion on Electric Vehicle Technology Based on Wheel Hub Motor Drive
First, the application background
As we all know, batteries, motors, and electronic control are the three core components necessary for new energy vehicles. The current new energy vehicles use motor drive systems to convert electrical energy into mechanical energy to power the car. Therefore, the drive motor is also one of the core technologies of new energy vehicles.
At present, concentrated motor drive is the main driving form of electric vehicle power. Although the advantages are obvious, that is, the arrangement of the transmission system and the control system is relatively simple, there are also some problems. Since the new energy vehicles driven by such motors have mechanical transmission components such as transmissions, clutches, and transmission shafts, the chassis structure is more complicated, and the effect is that the space is very narrow, and the transmission system transmits power through mechanical components. It will cause energy loss, resulting in low energy utilization.
In addition, this transmission system generates large noise during the driving of new energy vehicles, and the comfort of the passengers cannot be guaranteed. Experts and scholars from abroad have carried out technical research on wheel hub motor drive in the early years, thus optimizing the compactness and energy utilization efficiency of motor drive in the chassis of new energy vehicles. Research on the driving technology of hub motor in domestic related institutions and units Still shallow. At present, the wheel motor drive technology has been applied to some new energy vehicles and has made good progress.
