An electric axle apparatus for a commercial vehicle may minimize the frequency of use of a main brake during braking, and may include a first clutch device disposed between an electric machine and a differential case to transmit or block power, a second clutch device disposed between the electric machine and the differential case to transmit or block power, and an electromagnetic brake disposed between the electric machine and the differential case. The second clutch device is arranged between the differential shell and the brake disc; the electromagnetic brake applies a braking force to the brake disc, and when the vehicle is coasting, kinetic energy transmitted from the drive shaft to the motor is blocked by separating the first clutch device and separating the second clutch device just like neutral engagement of the transmission, so that coasting distance can be increased and energy efficiency and durability of the motor can be improved.

    本发明涉及用于商用车辆的电动车桥装置,所述装置可以使制动时主制动器的使用频率最小化,其可以包括第一离合器装置、第二离合器装置、电磁制动器,所述第一离合器装置设置在电机和差速器壳之间,以传递或阻断动力;所述第二离合器装置设置在差速器壳和制动盘之间;所述电磁制动器对制动盘施加制动力,当车辆滑行时,通过分离第一离合器装置和分离第二离合器装置,就像变速器的空挡接合一样,则从驱动轴传递至电机的动能被阻挡,从而可以增加滑行距离并且提高能量效率和电机的耐久性。
