[0002] Existing brake chassis all have built-in heat dissipation functions. There are generally two ways to ventilate brake discs, one is wind-swinging heat dissipation, and the other is impact wind heat dissipation. Impact wind heat dissipation is easy to understand, that is, to introduce cold air through the air duct to cool the brake pads; while wind-swinging heat dissipation allows cold air to enter the brake disc through the gaps between the brake pads, and the hot air is thrown out by the rotating force, thereby cooling the brake pads. It is the most common way to dissipate heat for brake discs. Such an air-cooled heat dissipation structure has low heat dissipation efficiency and limited heat dissipation effect.
