The invention discloses an electric vehicle driving system with a cooling system, which comprises a gearbox, a vehicle rod movably connected in the gearbox, wheels connected to two ends of the vehicle rod, and a driving motor in transmission connection to the surface of the gearbox, and a heat dissipation structure for dissipating heat of the motor is arranged on the surface of the gearbox. The heat dissipation structure comprises a transmission case fixedly connected to the top of the gearbox, and the transmission case is located on the top of the driving motor. The reciprocating screw rotates, threads on the surface of the reciprocating screw push the support to horizontally move in a reciprocating mode, the support guides airflow through the cooling fan on the inner side in the moving process, the contact uniformity of the airflow and the driving motor is improved, the heat dissipation mode of the equipment can be improved, and the heat dissipation efficiency is improved. Heat is dissipated instead of a contact heat exchange mode, the situation that the temperature accumulated on the surface of an exchange heat dissipation material cannot be effectively eliminated is prevented, the heat is prevented from being reversely exchanged into the driving system, and normal running of the driving system is guaranteed.
本发明公开了一种带有冷却系统的电动车驱动系统,包括变速箱,活动连接在变速箱内部的车杆,连接在车杆两端的车轮,传动连接在变速箱表面的驱动电机,所述变速箱的表面设置有用于散热电机的散热结构,所述散热结构包括固定连接在变速箱顶部的传动箱,所述传动箱位于驱动电机的顶部。本发明通过往复螺杆旋转并利用往复螺杆表面的螺纹推动支架往复水平移动,支架在移动过程中利用内侧的散热扇对气流进行引导,提高气流与驱动电机的接触均匀度,能够改进该设备的散热方式,替代通过接触热交换的方式对热量进行散发,防止交换散热材料表面聚集的温度无法有效消除,避免热量反向交换至驱动系统的内部,保证驱动系统的正常行驶。
