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

A wear-resistant noise-reduction automobile half shaft, comprising: a flange (1) used for connecting a bridge body, a half shaft rod (2) integrally formed with the flange (1), and a spline shaft (3) formed on the end of the half shaft rod (2), a plurality of bolt connection holes (4) being formed on the flange (1), and a recessed groove (5) being formed in the centre position of the face of the flange furthest from the spline shaft (3), a pair of lugs (6) being arranged symmetrically between the recessed groove and the upper surface of the flange (1), and a centre hole (7) being formed on the end of the spline shaft (3) for connection to a wheel hub. The advantages thereof are: the structure of the automobile half shaft is novel, and the recessed groove (5) and the lugs (6) arranged on the upper surface of the flange (1) improve the wear resistance and noise reduction capability of the automobile half shaft; in addition, a composite coating layer coated on the surface of the automobile half shaft further improves the performance of the automobile half shaft; when the components synergise, the noise level of the automobile half shaft reaches an optimum Z1 level and the rate of abrasion is reduced to 1.5% or lower, improving the comfort and stability of product use.

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...
