Abstract
The utility model discloses a drive shaft which comprises a flange plate, an oil seal neck, a bearing neck, a threaded neck, a cylinder, a shaft body, a step element and a spline. The flange plate, the oil seal neck, the bearing neck, the threaded neck and the cylinder are arranged at the left end of the shaft body from left to right successively. The step element and the spline are arranged at the right end of the shaft body from left to right successively. Hardening layers are arranged on the surfaces of the oil seal neck, the bearing neck, the cylinder, the step element and the spline, the depth of the hardening layer on the surface of the spline is in a range of 1.2mm to 2mm, and the depths of the hardening layers on the surfaces of the oil seal neck, the bearing neck, the cylinder and the step element are in a range of 1.2mm to 3mm. The drive shaft has good anti-abrasion performances, not easy to break and damage and long in service life.
Description
Technical field
The utility model relates to axle drive shaft.
Background technology
The automobile jack shaft is in the bottom, chassis, is used for the output torque of differential side gear is passed on drive wheel or the wheel reduction gear, and traditional automobile jack shaft is easy to wear and cause early stage damage.
Summary of the invention
Problem to be solved in the utility model provides axle drive shaft, and is wear-resisting, hardness good, long service life.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: axle drive shaft, comprise flange, the oil sealing neck, bearing neck, screw neck, cylinder, axis body, ladder body and spline, described flange, the oil sealing neck, bearing neck, screw neck and cylinder are located at the left end of axis body from left to right successively, described ladder body and spline are located at the right-hand member of axis body from left to right successively, described oil sealing neck, bearing neck, cylinder, the surface of ladder body and spline is equipped with subzero treatment, the depth of hardening of described splined surfaces is 1.2～2mm, described oil sealing neck, bearing neck, the depth of hardening of cylinder and ladder surface is 1.2～3mm.The different position of axle drive shaft has its suitable subzero treatment, makes semiaxis have good resistance to abrasion, long service life.
Improved, the diameter of described axis body is less than cylindrical diameter, described ladder body comprises left part and right part, the diameter of described left part is identical with cylindrical diameter and greater than the diameter of right part, described left part and axis body, cylinder and axis body are all by arc transition, and the diameter of described right part is identical with the big footpath of spline.Make axle drive shaft have good intensity, not frangibility.
Improved, be provided with relief groove between described bearing neck and the screw neck.The processing that guarantees screw thread puts in place.Improved, the width of described relief groove is 3mm.
Improved, arc transition is all passed through in the diapire of described relief groove and two side.Avoid stress to concentrate, guarantee the integraty of axis body.
Improved, the left end of described flange is provided with the supporting shoulder.
Improved, described flange end face is provided with bolt hole.
Improved, the right-hand member of described spline is provided with screw hole.
Beneficial effect:
After adopting technique scheme, this utility model axle drive shaft has good abrasion resistance, and frangibility is not damaged, long service life.
