The embodiment of the invention discloses a driving system of an electric wheel loader. The driving system comprises a power control unit; the electric driving front axle is connected with the power control unit and comprises a driving front axle and a first motor which are directly connected; the electric driving rear axle is connected with the power control unit and comprises a driving rear axle and a second motor which are directly connected; and the oil pump motor is connected with the power control unit and is used for providing power for an oil cylinder, a brake system and an auxiliary pipeline of the loader. According to the driving system of the distributed wheel loader, the three motors including the front axle motor, the rear axle motor and the oil pump motor are achieved, the mode that the motors are directly connected with the axles is adopted on the electric driving rear axle and the electric driving front axle respectively, mechanical structure connection in transmission is not needed, and more reasonable space layout is achieved; the device can be widely applied to various small wheel loaders.
本说明书实施例公开了一种电动轮式装载机的驱动系统，包括：功率控制单元；连接所述功率控制单元的电动驱动前桥，所述电动驱动前桥中包括直连的驱动前桥和第一电机；连接所述功率控制单元的电动驱动后桥，所述电动驱动后桥中包括直连的驱动后桥和第二电机；连接所述功率控制单元的油泵电机，所述油泵电机用于向所述装载机的油缸、刹车系统和辅助管路提供动力。从而实现前桥电机、后桥电机和油泵电机三电机的分布式轮式装载机的驱动系统，在电动驱动后桥和电动驱动前桥上分别采用了电机和桥直连的形式，从而无需在传动中的机械结构连接，实现更为合理的空间布局，可以广泛应用于各式小型的轮式装载机中。
