The coaxial motor axle assembly with the cooling device comprises an axle shell, the outer surface of the axle shell is sleeved with an annular sealing cover, an oil pipe is inserted into the outer surface of the annular sealing cover, a micro pump is installed on the upper end face of the axle shell in a threaded mode, and the side, away from the micro pump, of the oil pipe is sleeved with an electromagnetic valve; the side, away from the electromagnetic valve, of the oil pipe is sleeved with a cooling assembly, an inner ring is rotationally installed on the inner wall of the outer ring, and sealing assemblies are bonded to the positions, located on the two sides of the inner ring, of the inner wall of the outer ring. The mode that cooling oil is injected through the annular sealing cover cannot cause resource waste, parts cannot be rusted, hot oil can be quickly cooled and can be recycled within a short time, the cooling effect is better, the inner ring of the hollow shaft can be avoided, the situation that the hollow shaft is abraded due to friction of the bearing unit can be avoided, and the service life of the hollow shaft is prolonged. The service life of the hollow shaft can be prolonged, gaps are not prone to occurring in the sealing assemblies on the bearing units, and the sealing effect is better.
本发明公开了一种带有冷却装置的同轴电机车桥总成,包括桥壳,桥壳的外表面套接有环形密封罩,环形密封罩的外表面插接有油管,桥壳的上端面螺纹安装有微型泵,油管远离微型泵的一侧套接有电磁阀,油管远离电磁阀的一侧套接有冷却组件,外圈的内壁转动安装有内圈,外圈的内壁且位于内圈的两侧均粘接有密封组件。本发明使用环形密封罩注入冷却油的方式不会造成资源浪费,也不会对零部件造成锈蚀,并且热油能够快速冷却,短时间之内可循环使用,冷却效果更好,并且能够避让空心轴的内圈,可避免空心轴被轴承单元摩擦导致磨损,能够延长空心轴的使用寿命,并且轴承单元上的密封组件难以出现缝隙,密封效果更好。
