Abstract
The utility model provides a hub motor lead wire, a hub motor assembly and an electric vehicle, the hub motor lead wire comprises a cable, a sealing sleeve and a protective sleeve, the sealing sleeve is sleeved on the cable in an interference fit manner, and the sealing sleeve is provided with a plurality of circles of elastic sealing parts which are in interference fit with a wire passing hole on a motor shaft. Therefore, the sealing sleeve can tightly wrap the outer surface of the cable and abut against the inner surface of the wire passing hole, waterproof sealing between the cable and the wire passing hole is achieved, normal operation of the hub motor in various environments can be effectively guaranteed, the service life of the hub motor is prolonged, and the vehicle using experience of an electric vehicle user is guaranteed. Furthermore, the protective sleeve sleeves the cable in an interference fit manner and is close to the sealing sleeve, so that the cable can be prevented from being in direct contact with the hole end of the wire passing hole through the protective sleeve in the process of arranging the sealing sleeve into the wire passing hole and the process of adjusting the mounting position of the sealing sleeve in the wire passing hole; therefore, the cable is not easy to damage in the process, and installation and adjustment are more convenient.
