Embodiment Construction

[0026] The embodiments of the present invention are described in detail below, and these embodiments are only used to explain the present invention, but not to be construed as limiting the present invention.

[0027] refer to figure 2 , the present invention is achieved through the following technical solutions:

[0028] An automobile brake disc, the appearance of the brake disc 3 is the same as that of the prior art brake disc 1, and the flow direction of the internal fins 4 of the brake disc is spirally twisted from the center to the edge; the spiral twist is adopted Kimedean spiral structure.

[0029] The material of the automobile brake disc is vermicular graphite cast iron; the outer surface of the brake disc is treated with boronizing.

[0030] A kind of preparation method of automobile brake disc:

[0031] 1) Select raw iron; the weight percent of each element in the raw iron is 3.6-3.8% carbon, less than 1.2% silicon, less than 0.04% sulfur, 0.3-0.9% manganese, 0.0...

Abstract

The invention relates to an automobile brake disc and a manufacturing method thereof. The appearance of the automobile brake disc is same with that of the brake disc in the prior art. The automobile brake disc is characterized in that the rotating direction of a fin in the brake disc is in spiral torsion from the center to the edge, and the spiral torsion is of an Achimedean spiral structure. Thematerial of the automobile brake disc is compacted graphite iron, and the outer surface of the brake disc is subjected to boronizing treatment.

Description

technical field [0001] The invention relates to the field of casting engineering materials, in particular to an automobile brake disc and a preparation method thereof. Background technique [0002] The fins 2 of the brake disc 1 used at the present stage are straight spokes, such as figure 1 As shown, the brake gas dissipates quickly through these fins, and the heat taken away is limited, which will cause a large amount of heat generated during braking to accumulate at the brake disc, which will have a thermal effect on the brake disc and reduce the life of the brake disc. [0003] At the same time, the brake discs used at this stage are generally made of gray cast iron. The manufacturing method of gray cast iron is simple and easy to produce, but gray cast iron also has serious defects, that is, weak processing ability, low tensile strength and poor shear stress. Therefore, the brake disc made of gray cast iron is easy to crack, has low comprehensive thermal fatigue resis...
