Description

Technical Field

[0001] This utility model relates to the technical field of automotive braking components, specifically an automotive brake drum. Background Technology

[0002] The brake drum is the core component of a drum braking system, mainly used for vehicle deceleration or stopping. The brake drum works in conjunction with the brake shoes to convert the kinetic energy of the wheel into heat energy through friction, thereby slowing down the vehicle.

[0003] When a car needs to brake while in motion, the driver presses the brake pedal, and the braking mechanism pushes the brake pads, causing the brake pads to generate braking friction with the brake drum, thus stopping the car wheels and achieving braking. However, the brake drum of existing technology has a closed internal structure, and the heat generated during braking will accumulate inside it, resulting in a lack of heat dissipation, which will affect the service life of the car brake drum. Utility Model Content

[0004] The purpose of this utility model is to provide an automotive brake drum that solves the problem mentioned in the background art where the prior art automotive brake drum has a closed internal structure, and the heat generated during braking accumulates inside, resulting in an inability to dissipate heat.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automobile brake drum, comprising a brake drum body, wherein a heat dissipation mechanism is provided on the outer side of the brake drum body;

[0006] The heat dissipation mechanism includes an exhaust port, a duct, an air inlet, heat dissipation fins, a micro motor, an air pump, an exhaust pipe, a valve, internal threads, and a threaded head;

[0007] The exhaust port is fixedly connected to the output end of the brake drum body. The air duct is sleeved on the outside of the brake drum body. The air inlet is fixedly connected to the inner wall of the air duct. The heat dissipation fins are disposed on the outer wall of the air duct. The micro motor is fixedly installed on one side of the air duct. The air pump is detachably connected to the air duct. The exhaust pipe is fixedly connected to one end of the air pump. The valve is rotatably installed inside the air duct. The internal thread is disposed at the opening of the air duct. The threaded end is fixedly connected to the other end of the air pump.

[0008] Preferably, the exhaust port is fixedly connected to the air inlet, and the exhaust port, the air duct and the air inlet are internally connected.

[0009] Preferably, the valve is fixedly connected to the end of the output shaft of the micro motor, and the output shaft of the micro motor in the energized state is used to drive the valve to rotate.

[0010] Preferably, the valve rotated to a horizontal position is used to close the opening of the air duct, and the valve rotated to a vertical position is used to open the opening of the air duct.

[0011] Preferably, the internal thread is used for threaded connection of the threaded head, and the threaded head in the tightened state is used for fastening the air pump.

[0012] Preferably, the internal thread is used for threaded connection of the threaded head, and the threaded head in the tightened state is used for fastening the air pump.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This heat dissipation mechanism allows the air pump in the powered state to extract the heat inside the brake drum body through the air duct. The heat inside the brake drum body then flows into the air duct through multiple exhaust ports and air inlets, and is then discharged to the outside through the exhaust pipe. This increases the air circulation inside the brake drum body, completes brake heat dissipation, effectively avoids the accumulation of heat inside the brake drum body, and also achieves heat dissipation on the surface of the air duct by setting multiple heat dissipation fins.

[0023] Please refer to this carefully. Figure 2 The exhaust port 201 is fixedly connected to the air inlet 203, and the exhaust port 201, the air duct 202 and the air inlet 203 are internally connected.

[0024] In this embodiment, the heat inside the brake drum body 1 flows into the air duct 202 through multiple exhaust ports 201 and air inlets 203, and then is discharged to the outside through the air duct 202 and exhaust pipe 207.

[0025] Please refer to this carefully. Figure 3 The valve 208 is fixedly connected to the output shaft end of the micro motor 205, and the output shaft of the micro motor 205 in the energized state is used to drive the valve 208 to rotate.

[0026] In this embodiment: the micro motor 205 is powered on and operated, so that the output shaft of the micro motor 205 in operation drives the valve 208 to rotate, turning the horizontal valve 208 to a vertical state.

[0032] In this embodiment: the air pump 206 in the installed state is powered on and operated, so that the air pump 206 in the operating state evacuates air from the inside of the air duct 202.
