Detailed Description
In order to make the aforementioned and other features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
As shown in fig. 1-2, the present embodiment provides a high-strength automobile rear axle including a rear axle housing 1.
The rear axle housing 1 is integrally formed, and specifically, the rear axle housing 1 is formed by sand mold injection molding. The rear axle housing 1 includes a bearing portion 11, two drive connecting portions 12 and a fixing portion 13, the bearing portion 11 is spherical, a receiving groove 111 is formed in a surface of the bearing portion 11, and the receiving groove 111 is used for mounting a differential.
The driving connecting portions 12 are cylindrical, the two driving connecting portions 12 are connected to two sides of the bearing portion 11, the axes of the two driving connecting portions 12 are collinear, the driving connecting portions 12 are formed with through holes 122, and the through holes 122 are communicated with the accommodating groove 111. Specifically, a clamping table 121 is formed on the outward surface of the driving connecting portion 12, the diameter of the clamping table 121 is larger than that of the driving connecting portion 12, the through hole 122 penetrates through the surface of the clamping table 121, and when the through hole 122 penetrates through a rear-drive driving shaft, the clamping table 121 is used for clamping with a shell of the driving shaft. A second reinforcing plate 15 is connected between the lower end of the driving connecting portion 12 and the carrier portion 11.
The fixing portion 13 is cylindrical, the fixing portion 13 is formed with a through hole 131, the axis of the through hole 131 is collinear with the axis of the fixing portion 13, the fixing portion 13 is connected to the upper end of the bearing portion 11, specifically, a first reinforcing plate 14 is connected between the driving connecting portion 12, the fixing portion 13 and the bearing portion 11, and the fixing portion 13 is fixedly connected to the bearing portion 11 through the first reinforcing plate 14. Further, the first reinforcing rib 16 is connected between the fixing portion 13, the first reinforcing plate 14 and the bearing portion 11, and since most of the stress is required to be borne after the fixing portion 13 is fixed to the automobile chassis, the connection strength of the fixing portion 13 is enhanced by the first reinforcing rib 16. Fixed part 13 is global to be formed with the spacing hole 132 that runs through the lateral wall, spacing hole 132 is linked together with through-hole 131, fixed part 13 is used for linking firmly with the car bottom, the effect is for fixed rear-axle housing 1's position and orientation, pass through fixed part 13's through-hole 131 and dead lever through a dead lever and fix in the car bottom, rock around in order to prevent rear-axle housing 1, be formed with the same end hole with spacing hole 132 on the dead lever, insert with the end key and end the spacing on the realization rear-axle housing 1 horizontal plane in hole and spacing hole 132.
Having shown and described the fundamental principles and the principal features of the invention and its advantages, it will be understood by those skilled in the art that the present invention is not limited by the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
