Embodiment 1

[0035] Its structure of the automobile semi-axle of the present embodiment is referring to figure 1 , including: a flange 1 used to connect the bridge body, a half-shaft 2 integrally formed with the flange 1, and a spline shaft 3 formed at the end of the half-shaft 2, formed on the flange 1 There are several bolt connection holes 4 for connecting with the bridge body, a central hole 7 is formed at the end of the spline shaft 3 for connecting with the hub, and spline teeth are processed on the surface of the spline shaft 3 .

[0036] It should be noted that a groove 5 is formed in the middle of the side of the flange 1 away from the spline shaft 3, and a pair of lugs 6 are symmetrically arranged between the groove 5 and the upper surface of the flange 1. Compared with the groove 5 The depth of the upper surface of the flange 1 is 1 mm, and the intersection of the side wall and the bottom wall of the groove 5 is rounded, and the height of the lug 6 compared to the upper surface ...

Embodiment 2

[0038] The structure of the automobile half shaft of this embodiment is the same as that of Embodiment 1, specifically including: a flange 1 for connecting the bridge body, a half shaft 2 integrally processed with the flange 1, and a half shaft formed at the end of the half shaft 2 The spline shaft 3 at the top of the flange 1 is formed with a number of bolt connection holes 4 to connect with the bridge body, the end of the spline shaft 3 is formed with a central hole 7 to connect with the hub, and the surface of the spline shaft 3 is processed with spline teeth.

[0039]It should be noted that a groove 5 is formed in the middle of the side of the flange 1 away from the spline shaft 3, and a pair of lugs 6 are symmetrically arranged between the groove 5 and the upper surface of the flange 1. Compared with the groove 5 The depth of the upper surface of the flange 1 is 2 mm, and the intersection of the side wall and the bottom wall of the groove 5 is rounded, and the height of t...

Embodiment 3

[0042] Its structure of the semi-axis of the automobile of the present embodiment is identical with embodiment 1, and it is important to emphasize that: the surface of the semi-axis of the automobile is also coated with a thick composite coating of 5 micrometers (μm), and the composite coating consists of the following parts by weight Each component is made: 50 parts of solvent (all parts by weight, the same below), 30 parts of binder, 10 parts of hollow silica microspheres, 5 parts of nano-titanium dioxide, 4 parts of aluminum tripolyphosphate, 3 parts of diatomaceous earth part and 2 parts of surfactant. Among them, the solvent is composed of 3 parts of polyvinyl alcohol and 47 parts of deionized water; the average particle size of the silica hollow microspheres is 1-3 μm, and the average particle size of nano-titanium dioxide is 50-80 nm; the adhesive is epoxy resin, The surfactant is selected from sodium fatty acid methyl ester sulfonate, fatty alcohol ether phosphate or f...

Abstract

The invention discloses a wear-resisting and noise-reducing automobile semi-axle. The wear-resisting and noise-reducing automobile semi-axle comprises a flange disc for connecting a bridge body, a semi-axle rod and a spline shaft, wherein the semi-axle rod is integrally molded with the flange disc and the spline shaft is formed at the end part of the semi-axle rod; a plurality of bolt connecting holes are formed in the flange disc; a groove is formed in the middle of one side, faraway from the spline shaft, of the flange disc; a pair of convex lugs is symmetrically arranged between the groove and the upper surface of the flange disc; and a central hole is formed in the end part of the spline shaft so that the spline shaft is connected with a wheel hub. The wear-resisting and noise-reducing automobile semi-axle has the beneficial effects that the automobile semi-axle provided by the invention is novel in structure, and the groove and the convex lugs are arranged on the upper surface of the flange disc, so that the wear-resisting performance and the noise-reducing capability of the automobile semi-axle are certainly improved; furthermore, the performance of the automobile semi-axle is greatly improved through a composite coating arranged on the surface of the automobile semi-axle in a coating manner; when components have a synergistic effect, a noise grade of the automobile semi-axle reaches an optimal Z1 grade and the abrasion rate is wholly reduced to be lower than 1.5 percent, so that the comfort and the stability of utilizing a product are improved.

Description

technical field [0001] The invention relates to an automobile half shaft, in particular to a wear-resistant and noise-reducing automobile half shaft, belonging to the technical field of vehicle parts. Background technique [0002] The car half shaft is a solid shaft that transmits power between the differential and the driving wheels. Its inner end is connected with the differential half shaft gear, while the outer end is connected with the hub of the driving wheel. The torque transmitted from the differential After passing through the half shaft, hub, etc., it is finally transmitted to the wheel, which is an important part of the transmission torque in the drive train. From the perspective of the classification of the half-shaft, the half-shaft can be divided into three types: semi-floating, full-floating and 3 / 4 floating, of which the semi-floating and full-floating two forms are more widely used. Among them, the semi-floating half shaft not only transmits torque, but als...
