When the axle housing middle section and the axle tube are assembled on the axle of the mining vehicle, the axle housing middle section 1 and the axle tube 8 are generally pressed and then welded at present due to the large size of the whole axle; according to the requirements of a drawing, in the aspect of assembling the axle tube of the mining vehicle axle, because a certain included angle relation exists between two threaded holes 7 of an axle tube flange and an axle housing lug surface 9 in the horizontal direction, namely the axle housing lug surface and the two threaded holes are in a parallel state; if in the assembling process, the parallel relation between two threaded holes of the flange face of the axle tube and the bridge face of the axle housing cannot be effectively controlled, the problem that the adjusting arm cannot be effectively reset can occur when the adjusting arm of the air chamber support is assembled, so that the problem that the brake system of the whole vehicle is out of harmony is caused, and the brake system is even out of work.
When the axle tube is assembled on the axle of the mining vehicle, the whole axle is large in size, and the process of press mounting and welding the axle tubes at the middle section and two ends of the axle housing is generally adopted; because the shaft tube 8 and the axle housing middle section 1 are pressed and connected, a certain interference magnitude exists; before the axle tube is pressed, the two threaded holes of the flange surface of the axle tube and the angle of the bridge surface of the axle housing are adjusted and fixed well, and then the press fitting is carried out.
