Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0032] figure 1 , figure 2 and image 3 As shown, an air-cooled vehicle brake disc with an air duct includes an air duct, and the air duct is located between the inner brake disc and the outer brake disc; The column unit; the column unit includes a plurality of columns, and one end of the column is connected with the outer diameter of the inner brake disc and the outer brake disc; the column is in the shape of a drop. The drop-shaped design can speed up the flow of fluid in the plate, and has excellent heat dissipation performance. The plurality of column units are evenly distributed in the circumferential direction with the brake disc as the center, and the uniform distribution angle α is optimal between 25° and 35°.

[0033] The column unit includes a first column ...

Abstract

The invention provides an air-cooled automobile brake disk with an air duct. The air-cooled automobile brake disk comprises the air duct. The air duct is located between an inner brake disk body and an outer brake disk body. The air duct is internally provided with a plurality of stand column units distributed uniformly. Each stand column unit comprises a plurality of stand columns, one ends of the stand columns are connected with the outer diameter of the inner brake disk body and the outer diameter of the outer brake disk body; each stand column is in a water drop shape. Each stand column unit comprises the first stand column, the second stand column and the third stand column, the first stand column and the second stand column are in a half-water-drop shape, and the third stand column is in a fully symmetric water drop shape. By adopting the air-cooled automobile brake disk with the air duct, flowing of fluid in the disk can be accelerated, and the heat dissipation efficiency is excellent; a heat flow field between the brake disk bodies is stabilized through the water-drop-shaped stand columns; a stable heat flow is formed between the heat flow field and the outside and is greatly beneficial to heat exchange; and accordingly, the temperature of the brake disk can be lowered to a reasonable range within a short time, and the braking efficiency of a brake is guaranteed.

Description

technical field [0001] The invention relates to the field of brake discs of automobiles, driving vehicles or traffic equipment, in particular to an air-cooled vehicle brake disc with air ducts. Background technique [0002] Oil shortages, global warming, and car companies all over the world have put in a lot of effort to improve vehicle fuel economy. Specifically, the existing automobile lightweight technology has received extensive attention, and this technology can greatly reduce fuel consumption without affecting performance. [0003] Specifically, lowering the quality award of the vehicle chassis directly affects the performance of the vehicle as a whole, and further affects the fuel economy of the vehicle. In this case, the reduction of the unsprung mass of the body is directly related to the wheel drive load, which can effectively improve the fuel economy of the vehicle, so this related technology is beginning to develop rapidly. [0004] Among these effective techno...
