Description

Technical Field

[0001] The utility model relates to the technical field of trailer brake discs, in particular to a self-cooling brake disc for a disc-type trailer axle. Background Art

[0002] The brake disc is also called the brake disc. Simply put, it is a round plate. It 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 good braking effect and its performance is relatively stable. Trailers often need to travel long distances, so the requirements for brake discs are often more stringent.

[0003] The rotation of the wheel can drive the rotating shaft and the brake disc to rotate synchronously. When braking is required, the user starts the brake oil pump to supply oil to the brake cylinder. The cylinder presses against the brake pads to perform friction braking on both sides of the brake disc. Existing brake discs mostly adopt a circular disc structure with a straight heat dissipation cavity inside. When braking, although the heat dissipation cavity can allow air to pass through to achieve the purpose of heat dissipation, the heat carried away by the air is limited. When the brake disc heats up too quickly and cannot dissipate heat in time, it will cause the brake disc to bend and deform, produce vibration or abnormal noise, and the poor heat dissipation effect will lead to a short service life of the brake disc. Utility Model Content

[0004] The purpose of the utility model is to provide a self-cooling brake disc for a disc trailer axle, so as to solve the problem proposed in the above background technology that the existing brake discs mostly adopt a circular disc structure with a straight heat dissipation cavity provided inside. When braking, although the heat dissipation cavity can allow air to pass through to achieve the purpose of heat dissipation, the heat carried away by the air is limited. When the brake disc heats up too quickly and cannot dissipate heat in time, it will cause the brake disc to bend and deform, produce shaking or abnormal noise, and the poor heat dissipation effect will lead to a short service life of the brake disc.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a self-cooling brake disc for a disc trailer axle, comprising a brake disc body and a mounting plate:

[0006] The brake disc body has a plurality of heat dissipation baffles arranged inside the brake disc body, a heat dissipation cavity arranged between the heat dissipation baffles, a plurality of heat dissipation holes opened on the surface of the brake disc body and a wave groove arranged on the side of the heat dissipation baffles. The brake disc body rotates to allow air to pass through the heat dissipation cavity and the heat dissipation holes to take away the heat generated by the brake disc. The wave groove increases the contact area with the air to improve the heat dissipation efficiency. The mounting plate is arranged on the side of the brake disc body. The side of the mounting plate is provided with a plurality of mounting holes for mounting the brake disc body on the vehicle.

[0007] By adopting the above technical solution, when the brake disc body rotates, air will flow quickly through the heat dissipation cavity and be discharged from the heat dissipation holes. At the same time, the wave grooves arranged on the side of the heat dissipation baffle will increase the contact area between the heat dissipation baffle and the air, so that the heat accumulated in the brake disc body can be quickly taken away, causing the temperature of the brake disc body to drop rapidly, achieving the purpose of self-cooling.

[0008] Preferably, twelve heat dissipation baffles are provided in total, and the twelve heat dissipation baffles are in a central rotationally symmetrical structure around the axis of the brake disc body, and the gap between every two heat dissipation baffles constitutes a heat dissipation cavity.

[0009] By adopting the above technical solution, air can be allowed to flow through the heat dissipation cavity, so that the air can take away the heat on the heat dissipation baffle, thereby achieving the purpose of cooling.

[0010] Preferably, the heat dissipation holes are opened on both sides of the heat dissipation cavity and communicate with the interior of the heat dissipation cavity. There are three heat dissipation holes on one side of the heat dissipation cavity and six on both sides. The heat dissipation holes are evenly spaced on both sides of the heat dissipation cavity.

[0011] By adopting the above technical solution, the heat dissipation holes and the heat dissipation cavity can be interconnected, so that air can flow out of the heat dissipation cavity through the heat dissipation holes and take away the heat of the brake disc body.

[0012] Preferably, the brake disc body further has a communication hole opened on one side of the brake disc body, and the communication hole is connected with the innermost end of the heat dissipation cavity.

[0013] By adopting the above technical solution, air can enter the interior of the heat dissipation cavity through the connecting hole.

[0014] Preferably, the mounting plate further has a plurality of air suction cavities provided on the side surface of the mounting plate, and the air suction cavities are communicated with the connecting holes provided on the surface of the brake disc body.

[0015] By adopting the above technical solution, air can be sucked in through the provided air suction cavity and enter the heat dissipation cavity.

[0016] Preferably, there are twelve air suction cavities in total, and the twelve air suction cavities are in a central rotationally symmetrical structure around the axis of the brake disc body, and an inclined groove is provided inside the air suction cavity.

[0017] By adopting the above technical solution, the brake disc body can guide air into the heat dissipation cavity through the inclined grooves provided in the air suction cavity when the brake disc body rotates.

[0018] Preferably, the heat dissipation baffle is wavy, and wave grooves are provided on both sides of the heat dissipation baffle.

[0019] By adopting the above technical solution, the contact area between the heat dissipation baffle and the air can be increased, so that the air can take away more heat when flowing through the heat dissipation cavity, thereby increasing the speed at which the temperature of the brake disc body drops.

[0020] Compared with the prior art, the beneficial effect of the present invention is that by providing a brake disc body and a mounting plate, air can quickly flow through the heat dissipation cavity and be discharged from the heat dissipation holes when the brake disc body rotates. At the same time, the wave grooves provided on the side of the heat dissipation baffle will increase the contact area between the heat dissipation baffle and the air, so that the heat accumulated in the brake disc body can be quickly taken away, so that the temperature of the brake disc body drops rapidly, thereby achieving the purpose of self-cooling.
