Description

Technical Field

[0001] The utility model relates to the field of automobile brake rotors, in particular to an automobile brake rotor adapted to an air flow heat dissipation structure. Background Art

[0002] Automobile brake rotor refers to the rotating part in the automobile brake system, which is usually made of cast iron or alloy steel. Its main function is to convert the friction generated by the brake into heat energy, so as to slow down or stop the car. The brake rotor is used in conjunction with the brake pad. When the brake pedal is stepped on, the brake pad will cling to the brake rotor, slowing down the rotation speed of the wheel through friction, thereby achieving the braking effect;

[0003] The Chinese patent with publication number CN115949683A discloses a disc brake rotor, including a first brake pad, a second brake pad, and a heat sink disposed between the first brake pad and the second brake pad. During braking, the first brake pad and the second brake pad rub against the stator of the disc brake system, and the heat generated can be dissipated through the heat sink. Directly dissipating the heat from the first brake pad and the second brake pad further improves the heat dissipation efficiency of the disc brake rotor, thereby achieving the purpose of the present invention.

[0004] When the disc brake rotor of the above patent rotates and directs the airflow inward, the airflow will flow into the middle position of the rotor, and the heat will accumulate in the middle position of the rotor, causing the heat to be unable to be reduced quickly. The heat accumulation in the middle position of the rotor affects the heat dissipation efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide an automobile brake rotor adapted to an air flow heat dissipation structure, wherein the rotation of a connecting ring can drive a fixed ring to rotate, and the rotation of the fixed ring can drive a spiral guide strip to rotate. The rotation of the guide strip can make the high-temperature gas flow toward both sides of the outside of the automobile brake rotor, thereby avoiding heat accumulation inside, and solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automobile brake rotor adapted to an air flow heat dissipation structure, comprising a first fixing plate, a second fixing plate is arranged on one side of the first fixing plate, the first fixing plate and the second fixing plate are welded and fixed by a connecting ring, a fixing ring is arranged at the center position of the connecting ring, the periphery of the outer periphery of the fixing ring is welded and fixed to the connecting ring by a diverter ring, connecting disks are welded at both ends of the fixing ring, guide strips are arranged on the outer side of the fixing ring in a spiral direction toward the connecting disk, and the guide strips are welded and fixed to the fixing ring.

[0007] Preferably, an air inlet is arranged around one end of the interior of the connecting ring, and sixteen of the air inlets are evenly distributed around the interior of the connecting ring. A flow cavity for penetrating and air flowing is arranged at the middle position of the air inlet toward the connecting ring.

[0008] Preferably, a second limiting strip is provided at the lower end of the flow chamber.

[0009] Preferably, a first limiting strip is provided at the upper end of the interior of the flow chamber.

[0010] Preferably, a first heat dissipation bar is provided on one side of the first limiting bar, and the first heat dissipation bar is fixed to the second fixing plate by welding.

[0011] Preferably, a second heat dissipation bar is provided on the other side of the first limiting bar, and the second heat dissipation bar is fixed to the first fixing plate by welding.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. During the rotation of the first fixing plate, the second fixing plate and the connecting ring of the utility model, external air will flow into the flow cavity from the air inlet. After being squeezed by the first limiting strip and the second limiting strip, the inflowing air will contact the first heat dissipation strip and the second heat dissipation strip on both sides respectively. The second heat dissipation strip and the first heat dissipation strip absorb the heat generated at the positions of the first fixing plate and the second fixing plate, so that the heat is discharged from the positions of the second heat dissipation strip and the first heat dissipation strip. The heat flows toward the fixing ring along the position of the flow cavity. As the automobile brake rotor continues to rotate, the heat contacts the guide strips on both sides of the spiral. The guide strips in the rotating state can push the heat, so that the heat is discharged from the middle position of the automobile brake rotor, avoiding the heat from being retained in the middle position of the automobile brake rotor after flowing along the flow cavity, thereby improving the heat dissipation efficiency and heat dissipation effect.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to solve the problem that when the existing disc brake rotor rotates and directs the airflow inward, the airflow will flow into the middle position of the rotor, and the heat will accumulate in the middle position of the rotor, causing the heat to be unable to be quickly reduced, and the heat accumulation in the middle position of the rotor affects the heat dissipation efficiency, this embodiment provides the following technical solutions:

[0022] A vehicle brake rotor adapted to an air flow heat dissipation structure comprises a first fixing plate 1, a second fixing plate 2 is arranged on one side of the first fixing plate 1, and Figure 1 , Figure 2 and Figure 3 As shown, the first fixing plate 1 and the second fixing plate 2 are fixed by welding through a connecting ring 3, and braking is achieved after the brake pad contacts the first fixing plate 1 and the second fixing plate 2;

[0023] In this embodiment, an air inlet 4 is arranged around one end of the inner part of the connecting ring 3, and sixteen air inlets 4 are evenly distributed around the inner part. A flow cavity 12 for penetrating and air flow is arranged at the middle position of the air inlet 4 toward the connecting ring 3, as shown in FIG. Figure 3 and Figure 5 As shown, during the rotation of the connecting ring 3, the external gas flows into the flow cavity 12 through the air inlet 4, and the gas continues to flow and continuously passes through the flow cavity 12 as the connecting ring 3 rotates;

[0024] In this embodiment, the lower end of the flow chamber 12 is provided with a second limiting strip 11, and the upper end of the flow chamber 12 is provided with a first limiting strip 7. Figure 1 and Figure 2As shown, the first limiting strip 7 and the second limiting strip 11 are both welded and fixed to the connecting ring 3, and the inflowing air is restricted by the first limiting strip 7 and the second limiting strip 11, and the gas is restricted and moved to both sides, a first heat dissipation strip 8 is provided on one side of the first limiting strip 7, and the first heat dissipation strip 8 is welded and fixed to the second fixing plate 2, and a second heat dissipation strip 9 is provided on the other side of the first limiting strip 7, and the second heat dissipation strip 9 is welded and fixed to the first fixing plate 1, and the air is pushed by the first limiting strip 7 and the second limiting strip 11, so that the gas contacts the first heat dissipation strip 8 and the second heat dissipation strip 9 and completes the heat dissipation;

[0025] In this embodiment, a fixing ring 13 is disposed at the center of the connecting ring 3, and the outer periphery of the fixing ring 13 is fixed to the connecting ring 3 by welding through a diverter ring 10. Figure 4 As shown, the gas guided by the connecting ring 3 is diverted by the diverter ring 10 and diverted to both sides of the diverter ring 10.
