Abstract
The utility model discloses a half axle of a cross-country vehicle. The half axle of the cross-country vehicle comprises a flange plate end surface (1), a flange plate (2), a recess (3), a bearing neck (4), an axle body (5), a conical body (6), a spline tooth (7), a bolt hole (8) and a detachable threaded hole (9), wherein the flange plate (2) connected with a bridge body is arranged at one end of the axle body (5); the other end of the axle body (5) is provided with the spline tooth (7); the bolt hole (8) and the detachable threaded hole (9) are formed in the flange plate (2); the bearing neck (4) is arranged between the axle body (5) and the flange plate (2); the conical body (6) is arranged between the axle body (5) and the spline tooth (7); and quenching and magnetic flaw detection are needed on the surface of the half axle. The half axle of the cross-country vehicle disclosed by the utility model has the advantages of high strength and high workpiece quality; and the vehicle is suitable for running in mountainous regions, in hill regions, on uneven roads and in atrocious weathers.
Description
Technical field
The utility model relates to automobile axle shaft, is specifically related to a kind of cross country car semiaxis.
Background technology
Automobile axle shaft is the direct drive spare of wheel, is the strength member of transmitting torque.During automotive operation, the torque of driving engine output passes to semiaxis through multi-change speed and actuator, is passed on the wheel by semiaxis again, and propelling vehicle advances or retreats.Cross country car is in starting or upward slope or hill path and hills when exercising, and moment of torsion is very big, emergency braking or go on uneven road particularly, and service conditions is more abominable.Therefore to withstand shocks during semiaxis work, the effect of alternating bending fatigue load and torsion, require material therefor to have enough bending strengths, shear strength and toughness preferably.Machine up will be selected good process simultaneously, reduces the existence of stress concentration.
Mostly traditional semiaxis forging is what the mode of employing loose tooling forging on pneumatic hammer was produced, and technology falls behind, and forging precision is low, and surface quality is poor; Reject rate is high, and labor strength is big, and loose tool is perishable, and is easy to wear; Cost is high, and capacity rating is low, in can only carrying out, small batch production.
Summary of the invention
The purpose of the utility model is: a kind of cross country car semiaxis is provided, adopts pendulum to roll over the new process manufacturing, with the conical patrix that rolls to blank end face pressurized, a kind of job operation that blank progressively is shaped.Because the rotary forging distortion is local engagement sequence pressurization, its area of contact and unit pressure are all smaller, substitute the bulk deformation in conventional the forging with local deformation; Distortion is even, and workpiece quality is high, and metal streamline is good; Dimensional accuracy is high, and the cutting amount is few, the saving in material and the energy; Production efficiency is high, and noise is little, and work situation is good.
The technical scheme that the utility model technical solution problem is adopted is: a kind of cross country car semiaxis; This cross country car semiaxis comprises flange end face, flange, groove, bearing neck, axis body, cone, spline tooth, bolt hole and dismounting tapped bore; Axis body one end is provided with and pontic flange connecting dish; The other end spline tooth of axis body, flange are provided with bolt hole and dismounting tapped bore, are provided with bearing neck between axis body and the flange; Be provided with cone between axis body and the spline tooth, the surface of semiaxis needs through quenching and magnetic inspection.
The beneficial effect of the utility model is: intensity is high, and workpiece quality is high, and automobile adapts in mountain region, hills and road injustice and the rough weather exercises.
