The brake is a braking force component in a braking system for generating resistance force by friction to decelerate or stop a vehicle. The rotating element in the disk brake friction pair is a disk-shaped brake disk, and the end surface of the disk-shaped brake disk is used as a working surface.
As one of important elements of automobile braking, the quality problem of a brake disc is of great importance, and the brake disc on the market at present has slow heat dissipation, great weight and poor wading performance. The brake disc is high in temperature, and is deformed and cracked when meeting water, the brake distance is obviously lengthened, and the like.
Disclosure of Invention
The invention aims to provide a brake disc with double air ducts for heat dissipation, which can effectively solve the problem of heat dissipation of the brake disc.
In order to solve the above problems, the double-air-duct heat-dissipating brake disc of the present invention includes a disc body, the disc body is a disc-shaped structure, two end faces of the disc body are friction faces, and the double-air-duct heat-dissipating brake disc is characterized in that: radiating air ducts are regularly distributed on the friction surface of the disc body, and the air ducts form a net structure; between the air ducts are column-shaped bosses which form friction surfaces.
The improvement of the technical proposal is that the middle of the disk body is a solid part, two end faces of the middle solid part are uniformly distributed with column-shaped bosses to form a friction surface, and an air duct with a net structure is formed between the column-shaped bosses.
The technical proposal is further improved, the column-shaped lug bosses on one end surface of the disc body and the column-shaped lug bosses on the other opposite end surface are arranged in a staggered way to form a honeycomb structure; because two sides are arranged in a staggered manner, the double-air-duct radiating brake disc is formed, and the strength of the disc body is improved while the purpose of efficient heat radiation is achieved.
The technical scheme is further improved, a flange plate extends outwards from the end face of one side of the plate body, and bolt holes capable of being connected with a hub are formed in the flange plate; through the bolt and the hub connection, the installation and the disassembly are more convenient.
The technical scheme is further improved, a spigot is arranged on the flange plate, and the spigot on the flange plate and the spigot on the hub are correspondingly configured and limited; the design makes the installation of wheel hub and brake disc more stable, guarantees positioning accuracy, has improved the security performance.
The invention has the beneficial effects that: the disc body has the advantages that the structure is reasonable, the process is simple, the air ducts are regularly distributed on the friction surface, the weight of the disc body can be effectively reduced without influencing the quality of the disc body, the friction surface is formed by the cylindrical bosses, the friction force can be increased, the braking distance is reduced, the safety is improved, and the air ducts with the net structures are beneficial to fully radiating.

Shown in the figure: the disc comprises a disc body 1, a flange 2, a middle solid part 3, a left air duct 4, a right air duct 5, a left cylindrical boss 6, a right cylindrical boss 7, a spigot 8 and a threaded hole 9.
Detailed Description
The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the invention are shown.
For the sake of clarity, the two sides of the disk body are defined as the left side and the right side, the cylindrical surfaces are positioned as the left cylindrical boss and the right cylindrical boss, and the air duct is defined as the left air duct and the right air duct.
As shown in fig. 1, 2 and 3, the double-air-channel heat-dissipation brake disc comprises a disc body 1, wherein the disc body and a flange 2 are integrated, a threaded hole 9 is formed in the flange 2, and a spigot 8 is arranged on the inner side of the flange so as to be conveniently connected with and positioned on a hub; the disc body 1 is divided into three layers, the middle layer is a solid part, two end faces of the middle solid part 3 are connected with the left cylindrical boss 6 and the right cylindrical boss 7 into a whole, a left air duct 4 is formed between the left cylindrical bosses 6, a right air duct 5 is formed between the right cylindrical bosses 7, and the left cylindrical boss 6 and the right cylindrical boss 7 are respectively and uniformly distributed to form friction surfaces.
As shown in fig. 4, to express the staggered arrangement state of the friction surfaces on both sides, the left column-shaped bosses 6 and the right column-shaped bosses 7 are staggered, so that the left air duct 4 and the right air duct 5 are also staggered to form a honeycomb structure; because two sides are arranged in a staggered manner, the double-air-duct radiating brake disc is formed, and the strength of the disc body is improved while the purpose of efficient heat radiation is achieved.
In the present invention, the flange 2 is provided integrally with the disc body 1, which is an optimized embodiment; the disc body may have another structural arrangement.
By adopting the invention, when the automobile is braked, the net structure on the disc body increases the friction force, and the formed double-air-channel heat dissipation structure can efficiently dissipate heat and reduce the braking distance, thereby improving the safety performance.
