Description

Technical Field

[0001] The utility model relates to the technical field of automobile brake discs, in particular to a brake disc. Background Art

[0002] Braking is commonly known as "brake". It is the action of stopping or slowing down a running locomotive, vehicle, other transportation tools or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine, install a brake shoe, belt or disc adapted to it on the machine base, and generate a braking torque under the action of external force. The brake caliper controls two brake pads to clamp the brake disc on the wheel. When the brake pads clamp the disc, friction will be generated between the two. When a car is driving on a slippery or icy low-friction road, if excessive braking occurs, the wheel will be locked by the brake disc of the brake device and lose grip, causing the vehicle to lose the ability to control the direction. The brake disc is a metal disc made of alloy steel and fixed on the wheel, rotating with the wheel. When the vehicle is driving, the brake caliper clamps the brake disc to slow down or stop the vehicle. Generally, there are round holes on the brake disc, which is used to reduce weight and increase friction. There are many types of brake discs, which are characterized by thin walls and sand cores formed at the disc and the center. Different types of brake discs differ in disc diameter, disc thickness, and the size of the gap between the two discs. The thickness and height of the disc hub also vary.

[0003] Chinese utility model patent: Publication number CN205423627U discloses a brake disc, which is characterized in that it includes a disc body, a flow channel is arranged in the middle of the disc body, two disc surfaces of the disc body are connected by a middle connector, heat dissipation holes are arranged on the disc surface of the disc body, a hydrophobic groove is arranged on the disc surface of the disc body, a mounting disc is arranged on the disc body, and a mounting hole is arranged on the mounting disc.

[0004] In the existing technology, when CN205423627U is in use, heat is dissipated through the heat dissipation holes, thereby improving the heat dissipation efficiency of the disc body. At the same time, the setting of the drain groove can facilitate the drainage of the disc body. However, in actual use, the drain groove is located in the disc body. If muddy water enters the drain groove during the driving of the car, it will cause the drain groove to be easily blocked and the heat dissipation holes to be blocked, which will lead to problems with heat dissipation efficiency and drainage. Therefore, a brake disc is needed to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a brake disc which has the advantage of preventing the brake disc from being blocked by mud and water and causing the heat dissipation and drainage performance to be affected, thereby solving the problem in the prior art that the brake disc will be affected in heat dissipation and drainage performance if mud and water enter the drainage groove when the vehicle is running.

[0006] To achieve the above object, the utility model provides the following technical solution: a brake disc, comprising a mounting disc, wherein the mounting disc is provided with an inner disc body and an outer disc body at the upper and lower ends of the outer side thereof, and further comprising a drain groove;

[0007] The drain trough is arranged on the opposite side of the inner dish body and the outer dish body.

[0008] When using a brake disc in the technical solution, the brake disc is cast in one piece using a magnesium-aluminum alloy material. During installation, the inner disc body is connected to the vehicle's drive shaft, so that some space is reserved between the inner disc body and the rotating shaft through the installation disc, thereby facilitating the subsequent installation of the brake pad. When the vehicle is running, the brake disc rotates, and the mud and water entering the drain groove can only adhere to the drain groove. Since a connecting column is provided between the inner disc body and the outer disc body, air can circulate between the inner disc body and the outer disc body, so that when the vehicle is running, the mud and water in the drain groove can be thrown out, thereby ensuring the heat dissipation and drainage performance of the brake disc.

[0009] Preferably, the mounting plate is provided with mounting holes in a circular array, and the mounting holes pass through the mounting plate.

[0010] The mounting disc is provided with mounting holes in an annular array and the mounting holes are passed through the mounting disc, so that mounting bolts can be inserted into the mounting holes during use, thereby fixing the brake disc with the mounting bolts.

[0011] Preferably, an arc-shaped protrusion is provided on the upper surface of the inner disk body, and the cross-sectional dimensions of the inner disk body and the outer disk body match.

[0012] By providing an arc-shaped protrusion on the upper surface of the inner disc body, the friction between one side of the inner disc body and the brake pad is increased through the arc-shaped protrusion, thereby improving the braking effect.

[0013] Preferably, an arc-shaped protrusion is provided on the lower surface of the outer disk body, the lower surface of the outer disk body and the lower surface of the mounting disk are in the same plane, and a connecting column is provided on the outer side of the outer disk body opposite to the inner disk body.

[0014] By providing an arc-shaped protrusion on the lower surface of the outer disc body, the friction between one side of the outer disc body and the brake pad is increased through the arc-shaped protrusion, thereby improving the braking effect. By placing the lower surface of the outer disc body and the lower surface of the mounting disc in the same plane, a partial installation space is reserved between the inner disc body and the vehicle drive shaft when installing the brake pad, thereby facilitating the installation of the brake pad.

[0015] Preferably, the number of the connecting columns is six, and the six connecting columns are respectively located on opposite sides of adjacent drain grooves.

[0016] By locating the six connection columns on opposite sides of adjacent drain grooves, the drainage performance of the drain grooves will not be affected during use, and the connection stability between the inner plate body and the outer plate body is increased.

[0017] Preferably, the depth of the drain groove is set to one quarter of the thickness of the inner plate or the outer plate.

[0018] By setting the depth of the drain groove to one quarter of the thickness of the inner disc body or the outer disc body, the stability of the brake disc structure is not affected while the drainage performance of the brake disc is not affected.

[0019] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0020] The utility model provides a drain groove, and the drain groove is arranged on the opposite side of the inner disc body and the outer disc body. At the same time, a connecting column is provided on the outer side of the opposite side of the outer disc body and the inner disc body. When actually used, the brake disc is integrally cast by magnesium-aluminum alloy material. When installed, the inner disc body is connected to the transmission shaft of the vehicle, so that part of the space is reserved between the inner disc body and the rotating shaft through the installation disc, so as to facilitate the installation of the brake pad at a later time. When the vehicle is running, the brake disc rotates, and the mud and water entering the drain groove can only adhere to the drain groove. Since a connecting column is provided between the inner disc body and the outer disc body, air can circulate between the inner disc body and the outer disc body. Therefore, when the vehicle is running, the mud and water in the drain groove can be thrown out, so as to avoid the brake disc being blocked by mud and water and affecting the heat dissipation and drainage performance.

[0029] Specifically, the drain trough 5 is arranged on the opposite side of the inner tray 6 and the outer tray 4 .

[0030] By setting a drain groove 5, and setting the drain groove 5 on the opposite side of the inner disc body 6 and the outer disc body 4, at the same time, a connecting column 7 is provided on the outer side of the opposite side of the outer disc body 4 and the inner disc body 6. In actual use, the brake disc is integrally cast by magnesium-aluminum alloy material. During installation, the inner disc body 6 is connected to the transmission shaft of the vehicle, so that part of the space is reserved between the inner disc body 6 and the rotating shaft through the installation disc 2, so as to facilitate the installation of the brake pad in the later stage. When the vehicle is running, the brake disc rotates, and the muddy water entering the drain groove 5 can only adhere to the drain groove 5. Since a connecting column 7 is provided between the inner disc body 6 and the outer disc body 4, air can circulate between the inner disc body 6 and the outer disc body 4, so that the muddy water in the drain groove 5 can be thrown out when the vehicle is running, so as to avoid the brake disc being blocked by muddy water and affecting the heat dissipation and drainage performance.

[0031] Furthermore, mounting holes 3 are provided in a circular array on the mounting plate 2 , and the mounting holes 3 pass through the mounting plate 2 .

[0032] The mounting holes 3 are formed in a circular array on the mounting disc 2 and penetrate the mounting disc 2 , so that mounting bolts can be inserted into the mounting holes 3 during use, thereby fixing the brake disc with the mounting bolts.

[0033] Furthermore, an arc-shaped protrusion 1 is provided on the upper surface of the inner disk body 6 , and the cross-sectional dimensions of the inner disk body 6 and the outer disk body 4 match.

[0034] By providing an arc-shaped protrusion 1 on the upper surface of the inner disc body 6, the friction between one side of the inner disc body 6 and the brake pad is increased through the arc-shaped protrusion 1, thereby improving the braking effect.

[0035] Furthermore, an arc-shaped protrusion 1 is provided on the lower surface of the outer disk body 4 , and the lower surface of the outer disk body 4 and the lower surface of the mounting disk 2 are in the same plane. A connecting column 7 is provided on the outer side of the outer disk body 4 opposite to the inner disk body 6 .

[0036] By providing an arc-shaped protrusion 1 on the lower surface of the outer disc body 4, the friction between one side of the outer disc body 4 and the brake pad is increased through the arc-shaped protrusion 1, thereby improving the braking effect. By placing the lower surface of the outer disc body 4 and the lower surface of the mounting disc 2 in the same plane, a partial installation space is reserved between the inner disc body 6 and the vehicle transmission shaft when the brake pad is installed, thereby facilitating the installation of the brake pad.

[0037] Furthermore, the number of the connecting columns 7 is six, and the six connecting columns 7 are respectively located on opposite sides of adjacent drain grooves 5 .

[0038] By locating the six connection columns 7 on opposite sides of adjacent drain grooves 5, the drainage performance of the drain grooves 5 will not be affected during use, and the connection stability between the inner tray 6 and the outer tray 4 is increased.

[0039] Furthermore, the depth of the drain groove 5 is set to be one quarter of the thickness of the inner plate 6 or the outer plate 4 .

[0040] By setting the depth of the drain groove 5 to one-fourth of the thickness of the inner disc body 6 or the outer disc body 4, the stability of the brake disc structure is not affected while the drainage performance of the brake disc is not affected.

[0041] When the utility model is used, the brake disc is integrally cast by magnesium-aluminum alloy material. When installing, the inner disc body 6 is connected to the transmission shaft of the vehicle, so that part of the space is reserved between the inner disc body 6 and the rotating shaft through the installation disc 2, so as to facilitate the installation of the brake pad at a later time. When the vehicle is running, the brake disc rotates, and the muddy water entering the drain groove 5 can only adhere to the drain groove 5. Since a connecting column 7 is provided between the inner disc body 6 and the outer disc body 4, air can circulate between the inner disc body 6 and the outer disc body 4, so that when the vehicle is running, the muddy water in the drain groove 5 can be thrown out, thereby ensuring the heat dissipation and drainage performance of the brake disc.
