Abstract
The utility model discloses a ten-ton semitrailer axle which casts an axle body and two axle heads on both ends together. Because the axle body and the axle heads on both ends are cast into integration, the anti-bending strength of the trailer axle, the fatigue strength and toughness are increased, the boring processing of the assembly type axle body and the lathe work procedure matched with the axle heads and the trailer axle are simplified.
Description
The utility model relates to a kind of automobile axle, more specifically to a kind of semi-dragging truck axle.
At present, ten tons of semi-dragging truck axles of domestic use generally use outsourcing piece east wind platform axle housing, the axis body material adopts the casting of QT400-10 spheroidal graphite iron to form, the tween drive shaft body structure is a square, and axis body two ends aperture is crossed boring processing, is bumped into axle tube thereafter and combines.Because east wind platform axle housing is earlier axis body to be cast out, then with two stomidium boring processing, is bumped into axle tube again and combines, axis body and axle tube are not cast as an integral body.So in use, the anti-ageing intensity of axletree, strength at repeated alternation, toughness all can not satisfy the demand of ten tons of superimposed trailers, the normal turning manufacturing procedure that fracture takes place and must cooperate with it through the boring processing and the spindle nose of assembly type axis body.
The purpose of this utility model provides a kind of anti-ageing intensity that can strengthen axletree, strength at repeated alternation, toughness, and ten tons of semi-dragging truck axles of simplified processing process.
The solution that the utility model adopts is that axis body and spindle nose are poured into an integral body.Foundry technique is: interior → mould assembling → cast → sand removal → normalizing → machine up → axle two ends surface treatment that axis body model → casting mold → spindle nose blanking → spindle nose and axis body bound fraction processing → baking spindle nose → spindle nose is placed casting mold.
Because the utility model is cast as an integral body with axis body and spindle nose, increased the bending strength of axletree, strength at repeated alternation, toughness, support transmission trailer axle withstands shocks at transmitting torque, when alternating bending and tersional stress, easy fracture not.And simplified the turning manufacturing procedure that assembly type axis body boring processing and spindle nose cooperate with it.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is ten tons of semi-dragging truck axle construction scheme drawings.
3 is steel plate knock hole position among Fig. 1, and 2 are dress back-plate flange apparatus, and 5 are dress brake cylinder device.
In Fig. 1, shown axis structure, make axis body model → casting mold → spindle nose 1 blanking earlier and (adopt diameter 85, the trade mark be among the 45# carbon round steel in order to processing, improve the spindle nose quality) → axis body 6 and spindle nose 1 bound fraction processing → baking spindle nose 1 → spindle nose 1 placement casting mold be interior → and mould assembling → cast (utilizes the ZQ45# pouring molten steel, compare with QT40010, improve axis body 6 mechanical characteristicss) → sand removal → normalizing (improve trailer axialite phase constitution, improve the mechanical characteristics of axle) → machine up → axle two ends surface treatment.
Axis body adopts " worker " type structure 4 in the middle of of the present utility model, when having simplified " mouth " mold casting, needs the core technology that increases.
