Examples

Referring to fig. 1-3, the present invention provides a split heat dissipation brake disc, which comprises an annular disc 1, a parting bead 2 and a connecting piece 3, wherein the two discs 1 are connected by the parting bead 2 to form a disc body, the parting bead 2 uniformly divides an interlayer between the two discs 1 into a plurality of parts, a ventilation groove 4 is formed between the adjacent parting bead 2 and the two discs 1, when the disc body rotates, gas flows from an outer ring of the disc body to an inner ring and takes away the temperature on the disc 1, two ends of the gas ventilation groove 4 are respectively positioned at the outer ring and the inner ring of the disc 1, and the connecting piece 3 is detachably arranged at one side of the disc body. The connection 3 is intended for connection with a hub.

In a specific embodiment, referring to fig. 3, the connecting lines at two ends of the parting bead 2 form an acute angle with the diameter of the disc 1. The diameters of the parting strips 2 and the disc 1 are not coincident, the ventilation groove 4 is inclined, so that when gas is introduced into the ventilation groove 4 from the outer ring, the gas flows along the inclined ventilation groove 4, the flow of the gas is quickened, and the heat on the disc 1 is further quickly taken away.

In a specific embodiment, referring to fig. 1 and 3, a guide bar 5 is connected between the parting strips 2, and the guide bar 5 is located between two adjacent parting strips 2. The guide strips 5 between the division strips 2 can further separate the ventilation grooves 4 into a plurality of parts, the length of each guide strip 5 is shorter than that of each division strip 2, an air inlet of a gap between each guide strip 5 and each division strip 2 is positioned on an outer ring and communicated with the outside, and when the air is introduced between the division strips 2, the air in the gap between each division strip 2 and each guide strip 5 is driven to flow when flowing due to the large flow velocity in the ventilation grooves 4, and gas is pressed into the gap between each division strip 2 and each guide strip 5, so that heat dissipation of the disc 1 is accelerated.
