Description
Technical field
The utility model relates to automobile axle shaft, is specifically related to a kind of the Yellow River load-carrying diesel engine automobile semiaxis.
Background technology
The rotation of automobile two semiaxis is different, and hurry up in side, side is a little slower, and Here it is requires transmission shaft to need be furnished with diff.Diff is exactly allow the wheel on both sides turn over the different device of speed, and semiaxis is just connected on diff and receives on wheel again.Automobile axle shaft has full-floating and semi-floating two kinds.The equal existing defects of this two profiles formula: a fully floating axle transmitting torque, do not bear any counter-force and moment of flexure, fully floating axle is easy to dismounting, and the bolt of rear end plate only need backing out semiaxis during maintenance can extract semiaxis out, and wheel and axle housing support automobile in the same old way.Semifloating axle shaft is transmitting torque both, bears again whole counter-force and moment of flexure, and its supporting structure is simple, cost is low, but this semiaxis dismounting trouble, and if half axle fracture in running car, then easily cause the danger that wheel flies off.
The Yellow River load-carrying diesel engine automobile, power is large, carrying more than 100t, engine output torque is very large, and when especially automobile travels on turning, reversing, uneven road surface, moment of torsion is larger, therefore, the rear axle shaft that necessary supporting intensity is high, could adapt to its safety traffic requirement.
Summary of the invention
The purpose of this utility model is: provide a kind of the Yellow River load-carrying diesel engine automobile semiaxis, adopts alloy steel solid forging, takes different Technologies for Heating Processing, improve bulk strength and resistance to abrasion, enhance safe reliability after prtreatment to the function of surface of semiaxis.
The technical scheme that the utility model technical solution problem adopts is: this Yellow River load-carrying diesel engine automobile semiaxis comprises: axis body, flange, fitting surface, bolt connecting hole, mid frequency induction hardening region, flange centre hole, dowel hole mark, axle journal, splined end, spline hardened area, spline tooth, centre hole and pin shaft hole, the fitting surface of flange is provided with bolt connecting hole and pin shaft hole and dowel hole and marks.
In a kind of the Yellow River load-carrying diesel engine automobile semiaxis of the present utility model, described flange and axle journal intermediate location are provided with mid frequency induction hardening region, hardening penetration layer 2-3 millimeter.
In a kind of the Yellow River load-carrying diesel engine automobile semiaxis of the present utility model, described spline tooth depth of hardening is 3 millimeters, hardness HRC45.
In a kind of the Yellow River load-carrying diesel engine automobile semiaxis of the present utility model, described spline tooth surface hardening hardness is HRC50, and core hardness is HRC23.
In a kind of the Yellow River load-carrying diesel engine automobile semiaxis of the present utility model, spline circumference is provided with well-distributed spline tooth and spline.
The beneficial effects of the utility model are: structure is simple, cost is low, be easy to manufacture, improves bulk strength and resistance to abrasion, enhances safe reliability, extend the service life of semiaxis.
