Embodiment
The invention will be further described below in conjunction with the accompanying drawings：
As shown in Figure 1, 2, a kind of cooling system of lubricating oil of drive axle outer circulation, by driving axis 1, flowline, is returned
Oil pipe, lube oil cooler 3, check valve 5, unloading valve 4 are constituted, and driving axis 1 includes being arranged in bevel housing 13
Cooling oil pump 2, cooling oil pump 2 and drive bevel gear 6 are integrated.The power resources of cooling oil pump 2 are main to slow down in drive bevel gear 6
There are oil leab C, bevel housing oil outlet F, bevel housing spill port D on device housing 13；When the work of driving axis 1
When making, cooling oil pump 2 is sucked the lubricating oil of the bottom of driving axis 1 by oil leab C, enters lubricating oil by flowline
