Description

Technical Field

[0001] The utility model relates to the technical field of automobile brakes, in particular to a water-draining brake lining. Background Art

[0002] Automobile brakes utilize a brake transmission mechanism to press the brake lining against the brake drum, generating braking force. This allows the wheels to slow down or stop the vehicle in the shortest possible distance, ensuring safe driving and preventing slippage. When driving in adverse conditions, such as through puddles or in the rain, moisture can seep onto the brake linings, potentially causing water seepage. This can degrade the vehicle's braking performance, leading to accidents and overall reduced driving safety. Patent No. CN214036616U, titled "A Drum Brake Lining for Construction Vehicles with Water Gutters," features multiple drainage grooves on the end surface of the drum brake lining. Water on the end surface of the drum brake lining can drain through the grooves, but the end surface remains moist, forming a water film that can affect the lining's braking ability. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a water-draining brake lining.

[0004] According to the technical solution provided in the embodiment of the present application, the drainage-type brake lining includes a lining body, and the two lining bodies move relative to the two shells through a number of brake cylinders. A cylindrical airbag is provided between the shell and the lining body, and a water inlet pipe and a water outlet pipe are provided on the cylindrical airbag. The water inlet pipe is communicated with the hole on the end face of the lining body, and the water outlet pipe is fixed through the shell. The cylindrical airbag stretches and contracts as the lining body moves, so that the water on the end face of the lining body enters the water inlet pipe and is discharged through the water outlet pipe.

[0005] Furthermore, the two lining bodies are connected by a sliding rod, so that the lining bodies can be pressed toward and away from the brake drum through the brake cylinder.

[0006] Furthermore, both end surfaces of the cylindrical airbag are fixedly connected to the shell and the lining body respectively, so that when the lining body is braked, the cylindrical airbag is stretched to form negative pressure to absorb moisture.

[0007] Furthermore, an air storage cavity is provided inside the cylindrical airbag, and the water inlet pipe and the water outlet pipe are both connected to the air storage cavity to achieve the circulation of water and air.

[0008] Furthermore, one-way valves are provided on both the water inlet pipe and the water outlet pipe. The water inlet pipe is provided with a one-way water inlet valve, and the water outlet pipe is provided with a one-way water outlet valve, to facilitate the directional flow of water and gas.

[0009] Furthermore, a water-absorbing sponge is filled in the hole to facilitate the absorption of moisture on the braking end surface of the lining body.

[0010] Furthermore, the cylindrical airbag is made of soft plastic material, which is easy to stretch and compress.

[0011] To sum up, the beneficial effects of the present application are as follows: the device of the present application adopts the negative pressure principle to absorb the water on the end surface of the brake lining into the cylindrical airbag, thereby absorbing the moisture on the end surface of the brake lining to the greatest extent, and preventing excess moisture from forming a water film on the end surface of the brake lining, thereby affecting its braking ability; the moisture absorbed into the cylindrical airbag is compressed due to the relative movement of the brake lining until it is discharged from the area where the brake lining exists through the one-way valve, thereby achieving drainage.

[0016] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0017] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0018] Drain brake linings, such as Figure 1 and 2 As shown, two oppositely placed lining bodies 1 are both slidably sleeved on the slide rod 5, and a plurality of brake cylinders 2 are fixedly provided on two oppositely placed housings 3. One end of the brake cylinder 2 is suspended and fixedly connected to the lining body 1, and both end surfaces of the slide rod 5 are fixedly connected to the two housings 3 respectively.

[0019] like Figure 2As shown, a cylindrical airbag 4 is provided in the gap of the brake cylinder 2, and the front end face and the rear end face of the cylindrical airbag 4 are fixedly connected to the shell 3 and the lining body 1 respectively, and a plurality of holes 11 are provided on the braking end face of the lining body 1, and these holes 11 are connected to each other and connected to the water inlet pipe 41 on the cylindrical airbag 4, and the water outlet pipe 42 on the cylindrical airbag 4 is fixed through the shell 3.

[0020] One-way valves are provided on both the water inlet pipe 41 and the water outlet pipe 42 to control the flow direction of water and gas.

[0021] During use, when the lining body 1 is braked by the brake cylinder 2, the brake cylinder 2 will move the two lining bodies 1 closer to the middle so that the end faces of the lining body 1 are pressed against the brake drum to achieve braking; when the two lining bodies 1 are closer to the middle, that is, the lining body 1 is away from the shell 3, since the two end faces of the cylindrical airbag 4 are respectively connected to the lining body 1 and the shell 3, the cylindrical airbag 4 is stretched at this time. At this time, the air storage cavity in the cylindrical airbag 4 is at a negative pressure compared with the pressure in the hole 11. At this time, according to the negative pressure adsorption principle, the water in the hole 11 can be sucked into the cylindrical airbag 4 through the water inlet pipe 41, and the moisture around the hole 11 can also be sucked in. At this time, the water on the braking end face of the lining body 1 is sucked into the cylindrical airbag 4, and the possibility of forming a water film on the end face of the lining body 1 will be reduced;

[0022] When the lining body 1 is no longer braking, that is, it returns to its original position through the brake cylinder 2, the two lining bodies 1 will approach the shell 3 connected to it through the brake cylinder 2 respectively, and the cylindrical airbag 4 will be squeezed. Since both the water inlet pipe 41 and the water outlet pipe 42 are provided with a one-way valve, when the cylindrical airbag 4 is squeezed, the water and air inside will be discharged from the shell 3 through the water outlet pipe 42, that is, away from the lining body 1, so that the cylindrical airbag 4 can absorb water again.

[0023] Filling the holes 11 with sponge can better absorb the moisture on the braking end surface of the lining body 1 , and then the moisture is sucked into the cylindrical airbag 4 through negative pressure.

[0024] The above description is merely an illustration of the preferred embodiments of the present application and the technical principles employed. The scope of the invention herein is not limited to the technical solutions formed by the specific combination of the aforementioned technical features, but also encompasses other technical solutions formed by any combination of the aforementioned technical features or their equivalents without departing from the inventive concept. For example, a technical solution formed by replacing the aforementioned features with (but not limited to) technical features with similar functions disclosed in this application.
