Three quenched bushes are pressed on the hollow spindle (sleeve) with a big interference fit, thus the spindle can move forward and backward precisely within the bush.
三个大干涉配合的淬火衬套压装在空心轴（镗套）上，因此，主轴能在衬套内前后精确移动；
The results show that stress in hollow beam and semi-shaft bush is much less than permissible stress, while joint of suspension frame and axle housing has too large local stress.
结果表明，驱动桥壳空心梁和半轴套管部分的应力远小于材料的许用应力，而悬架支座与桥壳连接处出现了局部应力过大的情况。
