Description

Technical Field

[0001] The utility model relates to the technical field of brake pads, and specifically relates to a brake pad. Background Art

[0002] Automobile brake pads, also known as automobile brake linings, refer to the friction materials fixed on the brake drums or brake discs rotating with the wheels. The friction linings and friction blocks therein bear external pressures and generate friction to achieve the purpose of vehicle deceleration. Automobile brake pads generally consist of steel plates, adhesive heat insulation layers, and friction blocks. The steel plates need to be painted to prevent rust. The friction blocks of existing brake pads are usually made of alloys, and the friction blocks are directly in contact with the air. After rainy weather or when the vehicle wades through water, the brake pads are prone to getting wet, which may lead to rusting of the friction blocks. The wet friction blocks will also cause a decrease in the friction force of the friction blocks, resulting in a longer braking distance and reducing the reliability of the device during use. Summary of the Utility Model

[0003] Aiming at the above problems, the purpose of the present utility model is to provide a brake pad to solve the problem that the friction blocks of existing brake pads are usually made of alloys and the friction blocks are directly in contact with the air. After rainy weather or when the vehicle wades through water, the brake pads are prone to getting wet, which may lead to rusting of the friction blocks. The wet friction blocks will also cause a decrease in the friction force of the friction blocks, resulting in a longer braking distance and reducing the reliability of the device during use.

[0004] To achieve the above purpose, the technical solution adopted by the present utility model is: a brake pad, including a steel plate and a friction block. Limit baffles are symmetrically installed above the steel plate, and an adhesive layer is bonded above the steel plate. An insulation layer is bonded above the adhesive layer. The friction block is bonded above the insulation layer, and a slot hole is provided in the middle part of the friction block. Water guiding holes are equidistantly arranged on the friction block, and a water guiding groove is provided inside the friction block.

[0005] The beneficial effect of the present utility model is that when the friction block comes into contact with water, the water seeps out through the water guiding holes and the water guiding groove, and the water guiding holes and the water guiding groove can accelerate the volatilization of the water, thereby reducing the drying time of the friction block and ensuring the reliability of the device during use.

[0006] To facilitate the water scraping of the limit baffle on the brake disc:

[0007] As a further improvement of the above technical solution: the cross-section of the limit baffle is arranged in a conical shape.

[0008] The beneficial effect of this improvement is that the conically arranged limit baffle can completely scrape the water on the brake disc, thereby reducing the phenomenon of braking force reduction caused by water.

[0009] To facilitate the contact between the friction block and the brake disc:

[0010] As a further improvement of the above technical solution: chamfers are provided on both sides of the friction block.

[0011] The beneficial effect of this improvement is that the friction block with chamfers can make it more convenient when the friction block contacts the brake disc.

[0012] For the convenience of water drainage:

[0013] As a further improvement of the above technical solution: the water guide holes and the water guide grooves are arranged in a through manner.

[0014] As a further improvement of the above technical solution: the water guide grooves are arranged in a mesh pattern.

[0015] The beneficial effect of this improvement is that when the friction block contacts water, the water seeps out through the water guide holes and the water guide grooves, and the water guide holes and the water guide grooves can accelerate the volatilization of water and also increase the heat dissipation efficiency of the friction block.

[0016] For the convenience of installing the limit baffle:

[0017] As a further improvement of the above technical solution: mounting holes are provided at both ends of the steel plate.

[0018] The beneficial effect of this improvement is that the steel plate can be firmly installed on the brake caliper through the mounting holes.

[0019] For limiting the friction block:

[0020] As a further improvement of the above technical solution: the inner side of the limit baffle is completely fitted with the side of the friction block.

[0021] The beneficial effect of this improvement is that the complete fitting of the limit baffle and the friction block can limit the position of the friction block by the limit baffle. Description of the Drawings

[0028] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present utility model.

[0029] As Figures 1-5 shown, a brake pad includes a steel plate 1 and a friction block 4. Limit baffles 11 are symmetrically installed above the steel plate 1, and an adhesive layer 2 is bonded above the steel plate 1. A heat insulation layer 3 is bonded above the adhesive layer 2. The friction block 4 is bonded above the heat insulation layer 3. A slot hole 41 is provided in the middle of the friction block 4. Water guide holes 42 are equidistantly arranged on the friction block 4. A water guide groove 43 is provided inside the friction block 4. When the friction block 4 comes into contact with water, the water seeps out through the water guide holes 42 and the water guide groove 43, and the water guide holes 42 and the water guide groove 43 can accelerate the volatilization of water, thereby reducing the drying time of the friction block 4, and further ensuring the reliability of the device during use. The cross-section of the limit baffle 11 is tapered. The tapered limit baffle 11 can completely scrape off the water on the brake disc, thereby reducing the phenomenon of braking force reduction caused by water. The two sides of the friction block 4 are chamfered. The chamfered friction block 4 can make it more convenient for the friction block 4 to contact the brake disc. The water guide holes 42 and the water guide groove 43 are in a through connection. The water guide groove 43 is in a mesh shape. When the friction block 4 comes into contact with water, the water seeps out through the water guide holes 42 and the water guide groove 43, and the water guide holes 42 and the water guide groove 43 can accelerate the volatilization of water. The water guide holes 42 and the water guide groove 43 can also increase the heat dissipation efficiency of the friction block 4. Installation holes are provided at both ends of the steel plate 1. Through the installation holes, the steel plate 1 can be firmly installed on the brake caliper. The inner side of the limit baffle 11 is completely attached to the side of the friction block 4. The complete attachment of the limit baffle 11 and the friction block 4 can limit the position of the friction block 4 by the limit baffle 11.

[0030] The working principle of the present utility model is as follows: When using this device, the device is installed on the brake caliper through the mounting holes. During braking, the friction block (4) contacts the brake disc to brake the vehicle. When the friction block (4) contacts water, the water seeps out through the water guide holes (42) and the water guide grooves (43). Moreover, the water guide holes (42) and the water guide grooves (43) can accelerate the volatilization of water, thereby reducing the drying time of the friction block (4), and then ensuring the reliability of the device during use. And during the use of the device, the water guide holes (42) and the water guide grooves (43) can increase the heat dissipation efficiency of the friction block (4), thereby reducing the phenomenon of reduced braking efficiency caused by high temperature. When braking in rainy days or when driving through water, the limit baffle (11) contacts the brake disc to scrape off the water on the brake disc, reducing the phenomenon of reduced braking force caused by water.

The description of the above examples is only used to help understand the method and its core idea of the present utility model. The above is only the preferred implementation manner of the present utility model.

For those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements, refinements or changes can be made, or the above technical features can be combined in an appropriate manner; these improvements, refinements, changes or combinations, or directly applying the concept and technical solution of the utility model to other occasions without improvement, shall all be regarded as the protection scope of the present utility model.
