Description

Technical Field

[0001] The utility model relates to the technical field of brake disc heat dissipation, in particular to a brake disc provided with heat dissipation holes. Background Art

[0002] The brake disc, in simple terms, is a round plate that rotates when the car is moving. The brake caliper clamps the brake disc to generate braking force. When you step on the brake, it clamps the brake disc to slow down or stop the car. The brake disc has a good braking effect and is easier to maintain than drum brakes.

[0003] Disc brake discs (discs) are divided into solid discs (single-piece discs) and duct discs (double-piece discs).

[0004] The solid disc type is easier for us to understand. To put it simply, it is solid.

[0005] The air duct plate, as the name implies, has a ventilation function. From the outside, it has many air ducts on the circumference leading to the center of the circle.

[0006] When the car is running, the air convection in the air duct achieves the purpose of heat dissipation, which is much better than the solid heat dissipation effect. Most cars are front-wheel drive, and the front disc is more worn out due to the frequency meter, so the front air duct disc and the rear solid disc (single disc) are used.

[0007] During the design process of the existing double-piece air duct disc, the space between the double-piece disc bodies is divided into air ducts leading to the center of the circle by ribs to achieve the purpose of heat dissipation. However, the air ducts are not connected to each other, resulting in poor airflow interactivity, which affects the heat dissipation efficiency of the air duct disc.

[0008] For this reason, we propose a brake disc with heat dissipation holes to solve the existing problems. Utility Model Content

[0009] The utility model aims to solve the problems existing in the background technology and proposes a brake disc with heat dissipation holes.

[0010] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a brake disc with heat dissipation holes, comprising an upper disc body, a lower disc body, ribs, disc body holes and connecting holes, the upper disc body and the lower disc body are connected and fixed to each other through the ribs, a shaft head is provided on a side of the upper disc body away from the lower disc body, disc body holes are equidistantly opened on the upper disc body and the lower disc body, and connecting holes are equidistantly opened on the ribs.

[0011] Preferably, the shaft head is provided with various mounting holes;

[0012] The positions of the mounting holes are distributed in a ring array relative to the upper end outer wall of the shaft head.

[0013] Preferably, the space between the upper disk body and the lower disk body is divided into various chambers by the shaft head, and the various chambers are interconnected through connecting holes.

[0014] Preferably, the plate body holes on the upper plate body and the lower plate body are respectively distributed in a circular array on the upper plate body and the lower plate body;

[0015] The positions of the various disk body holes and the positions of the various rib strips are staggered with each other.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] The brake disc with heat dissipation holes of the utility model can be fixed at a designated position of the wheel hub through the mounting hole of the shaft head during use, and the space between the upper disc body and the lower disc body is divided into air ducts leading to the center of the circle by the ribs. When the car is running, air convection is achieved through the air ducts to achieve the purpose of heat dissipation;

[0018] Furthermore, each rib is provided with a connecting hole, thereby greatly increasing the air interaction performance between each air duct, further improving the heat dissipation effect of the brake disc;

[0019] The utility model can form the effect of a large amount of air flowing in the brake disc, which is convenient for timely dissipating the heat generated by friction, accelerates the heat dissipation effect, and thus prolongs the service life of the brake disc.

At the same time, the design of each disc body hole 4 greatly enhances the interaction between the air duct and the external environment, further improving the heat dissipation of the brake disc.
