A wheel hub motor drive system is provided comprising a knuckle (1), a drive mechanism (2), a wheel bearing (3) and a brake system (4). In the axial direction (A) of the output shaft (24) of the driving mechanism (2), the driving mechanism (2) is located on one side of the installation part (11) of the steering knuckle (1), and the wheel bearing (3) and the braking system (4) are located on the other side of the installation part (11). An outer ring (32) of the wheel bearing (3) is detachably mounted on the mounting part (11), an inner ring (31) of the wheel bearing (3) is in transmission connection with the output shaft (24) through a spline, and a brake caliper mechanism of the brake system (4) is detachably mounted on the mounting part (11). According to the structural design, the steering knuckle and other structures of the hub motor driving system can be conveniently matched with different braking systems and wheel bearings, and dismounting and mounting of the steering knuckle and other structures of the hub motor driving system and the different braking systems and wheel bearings are facilitated, so that the universality of the hub motor driving system is improved. The invention further provides a motor vehicle comprising the hub motor driving system.

    提供了一种轮毂电机驱动系统,其包括转向节(1)、驱动机构(2)、车轮轴承(3)和制动系统(4)。在驱动机构(2)的输出轴(24)的轴向(A)上,驱动机构(2)位于转向节(1)的安装部(11)的一侧,车轮轴承(3)和制动系统(4)位于安装部(11)的另一侧。车轮轴承(3)的外圈(32)可拆卸地安装于安装部(11),内圈(31)与输出轴(24)通过花键传动联接,制动系统(4)的制动钳机构可拆卸地安装于安装部(11)。以上的结构设计都有利于本申请的轮毂电机驱动系统的转向节等结构与不同的制动系统和车轮轴承适配和拆装,由此本申请的轮毂电机驱动系统的通用性获得了改善。还提供了一种包括该轮毂电机驱动系统的机动车。
