The invention relates to the field of trucks, in particular to a truck electric drive axle with an auxiliary heat dissipation device. Driving motors are arranged at the left end and the right end of the shell respectively, first flanges are arranged on the left side and the right side of the shell respectively, the driving motors are connected to the two sides of the shell through inner rings of the first flanges, a heat dissipation assembly is arranged on the outer side of the shell and is close to the driving motors, and speed reducers are arranged at the working ends of the two driving motors respectively. The speed reducer is sleeved with a second flange. The invention has the following beneficial effects: by adopting an electric driving mode, the current environmental protection development requirement is met, and the driving efficiency can be improved; the multiple air inlet pipes are arranged on the two sides, close to the driving motor, of the shell correspondingly, air carried in the running process of the truck is conveyed into the shell through the air inlet pipes, then auxiliary heat dissipation is conducted on the driving motor, the fault occurrence rate is reduced, and the service life of the motor is prolonged.
本发明涉及卡车领域,尤其是涉及一种带辅助散热装置的卡车电驱动车桥,包括外壳;外壳的左右两端分别设置有驱动电机,外壳的左右两侧分别设置有第一法兰,驱动电机通过第一法兰的内环连接于外壳两侧,外壳的外侧设置有散热组件,散热组件靠近驱动电机设置,两个驱动电机的工作端上分别设置有减速机,减速机上套设有第二法兰;本发明的有益效果是:采用电驱动方式既符合目前环保发展要求,又能提高驱动效率;通过在外壳靠近驱动电机的两侧分别设置有若干个进风管,通过进风管将卡车行驶过程中携带的风传进外壳内,进而对驱动电机进行辅助散热,降低故障发生率,提高电机的使用寿命。
