Description

Technical Field

[0002] The brake drum is a key component used in the braking system of vehicles such as automobiles, motorcycles, and bicycles. It is mainly used in drum brake systems. The drum brake system is a traditional braking method that achieves deceleration and stopping through the friction between the brake shoe and the brake drum. It is usually installed on the wheel hub and rotates with the wheel. The heat-resistant brake drum with a composite structure is made by introducing new composite materials such as carbon fiber reinforced plastics or ceramic-based composites on the basis of traditional materials to improve its heat resistance and mechanical strength. The introduction of composite materials can not only significantly improve the heat resistance and thermal fatigue resistance of the brake drum, but also effectively reduce the weight of the brake drum, thereby improving braking efficiency and vehicle fuel economy.

[0003] However, most of the heat-resistant brake drums with composite structures in the prior art still have certain defects. For example, a through-hole structure is usually provided on such brake drums. Therefore, during use, foreign matter may enter the interior of the device through the through-holes on the brake drum, causing wear on the interior of the brake drum and affecting the braking performance of the vehicle. Secondly, although filter structures are provided on some through-holes, they are usually fixed thereon by welding or bolting, which makes them difficult to replace, or requires the use of tools such as wrenches to disassemble them, which is inconvenient.

[0026] Working principle: When the brake drum is working, under the action of the filter 5, foreign matter can be effectively prevented from entering the interior of the brake drum from the through hole 2, thereby improving the braking performance of the brake drum and reducing safety hazards. When the filter 5 needs to be replaced, it is only necessary to push the T-shaped block 9 upwards, drive the fixed block 8 to move upward along the slide rod 14 under the action of the slider 13, and compress the spring 15, so that the plug post 12 is disengaged from the inside of the hole 16, and flip the connecting rod 11 around the fixed column 10, so that the restriction on the filter 5 can be released, and then the filter 5 can be pulled out along the slide groove 4 to complete the disassembly of the filter 5 as a whole, and then the new filter 5 is inserted into the slide groove 4, and the T-shaped block 9 is pushed upwards again, and the connecting rod 11 is flipped around the fixed column 10. When the plug post 12 corresponds to the hole 16, the T-shaped block 9 is released.

This process does not require the aid of other tools and is simple and convenient.
