Abstract
The utility model discloses a lorry rear axle half shaft. The lorry rear axle half shaft is characterized in that one end of a shaft body (10) of the half shaft is provided with a flange plate (3) which is connected with a rear axle body, the flange plate (3) is provided with bolt holes (12) and a seam allowance (2), a position which is close to the flange plate (3) is provided with a cone (5), a cylinder (6) and a bearing neck (7). The other end of the shaft body (10) is provided with multiple keys (11), the surface of the half shaft needs quenching and magnetic flaw detecting, the seam allowance (2) is processed into be a hollow body (1), the bearing neck (7) is provided with a backstop ring groove (8), and a cone (9) is arranged between the bearing neck (7) and the shaft body (10). The lorry rear axle half shaft is simple in structure, low in cost and easy to manufacture, improves whole strength and abrasion performance, enhances safety and reliability, and prolongs the service life of the half shaft.
Description
Technical field
The utility model relates to car rear axle semi-axis, is specifically related to a kind of autotruck rear axle shaft.
Background technology
Automobile axle shaft is a transmission shaft, needs behind the automobile traveling to turn, and the rotation of both sides wheel is different, and a side is hurried up, and a side is a little slower, and Here it is requires need be furnished with diff on the transmission shaft.Diff is exactly to let the wheel on both sides turn over the different device of speed, and semiaxis just is connected on the diff and receives on the wheel.
The autotruck semiaxis because load carrying ability is big, bears the synthesis of moment of torsion and moment of flexure, produces the semiaxis fracture by cycling stresses, tensile stress and three kinds of combineds action of plastic stress.The major cause of off-axis is caused by the following aspects basically: the off-axis that (1) defect in material causes, and it has reduced the intensity of material, has played the effect of breach, has produced in indentation, there and has split the source, and crackle is expanded thus, causes last off-axis.(2) the improper off-axis that causes of design, some semiaxis are that design is not enough, mainly are that axle is thin and the transition shoulder circular arc is less, very easily produce bigger stress concentration, in long-term use, in the service life that often out of reach limited, off-axis then occurs.(3) the improper off-axis that causes of processing.(4) semiaxis tapering and wheel hub tapering are misfitted, and the wheel hub swing also can cause off-axis.(5) use and keep in repair the improper off-axis that causes, semiaxis is worked under high speed and high pressure, the unequal condition of road, and long-term overload is gone, and stop washer lost efficacy, and long-term oil starvation is because of het expansion also can cause tired off-axis.
Summary of the invention
The purpose of the utility model is: a kind of autotruck rear axle shaft is provided, adopts the alloy steel solid forging, after the prtreatment function of surface of semiaxis is taked different Technologies for Heating Processing, improved bulk strength and resistance to abrasion, strengthened safe reliability.
The technical scheme that the utility model technical solution problem is adopted is: axis body one end of this autotruck rear axle shaft is provided with and pontic flange connecting dish; On flange, be provided with the seam that bolt hole and pontic cooperate; Close on the flange place and be provided with cone and cylinder and bearing neck; The other end of axis body is provided with spline, and the surface of semiaxis needs through quenching and magnetic inspection.
The autotruck rear axle shaft of the utility model is provided with the stopping annular groove on bearing neck.
The autotruck rear axle shaft of the utility model is provided with cone between bearing neck and axis body.
The beneficial effect of the utility model is: simple in structure, cost is low, be easy to make, and has improved bulk strength and resistance to abrasion, has strengthened safe reliability, has prolonged the service life of semiaxis.
