本发明的车轮1工作时，电机13的转子带动电机轴132转动，电机轴132带动驱动体12和轮毂11转动，电机13与轮毂11之间无需设置减速机构，与现有技术相比，结构简单，密集紧凑，传动精度高，降低加工精度和加工难度，故障率低，维护周期短，便于维修，使用和维修成本低，延长使用寿命。
优选地，电机为低速大扭矩电机，更适用于直接驱动轮毂11转动，例如低速大扭矩电机为永磁低速大扭矩电机，当然还可以是其它低速大扭矩电机。
如图1、图2、图3、图4所示，进一步，驱动体12呈筒状，驱动体12包括环状的本体121、端盖122和环状的延伸部123，本体121的一端连接端盖122，本体121的另一端为敞口端，延伸部123自端盖122朝本体121的敞口端延伸，本体121套在电机13的外壳131与轮毂11之间，延伸部123套接在电机轴132外，例如，驱动体12的延伸部123与电机轴132键连接，为将电机轴132与驱动体12的延伸部123轴向固定，可在延伸部123的端部设置一压盖14，压盖14抵靠驱动体12的端盖122，并与电机轴132的端部通过螺栓固定连接。

本发明还提供一种矿用卡车，其包括上述的车辆的行走装置。
本发明的矿用卡车工作时，电机13的转子带动电机轴132转动，电机轴132带动驱动体12和轮毂11转动，电机13与轮毂11之间无需设置减速机构，与现有技术相比，结构简单，密集紧凑，传动精度高，降低加工精度和加工难度，故障率低，维护周期短，便于维修，使用和维修成本低，延长使用寿命。
优选地，电机为低速大扭矩电机，更适用于直接驱动轮毂11转动，例如低速大扭矩电机为永磁低速大扭矩电机，当然还可以是其它低速大扭矩电机。
本发明的车轮1通过采用低速大扭矩的电机13直接驱动驱动体12和轮毂11转动，无需设置减速机部分，非常适用于大型矿用卡车，减少了故障点，大幅降低使用和维修成 本，延长使用周期。
