Abstract
Description
Technical Field
[0001] This utility model belongs to the field of brake pad technology, specifically a heat dissipation brake pad. Background Technology
[0002] As one of the core components of a car's braking system, brake pads directly affect the safety and reliability of vehicle operation. Their working principle primarily involves converting the vehicle's kinetic energy into heat energy through intense friction between the friction material and the brake disc (or drum), thereby achieving vehicle deceleration or stopping.
[0003] In existing technology, conventional brake pads typically consist of a metal backing plate and a layer of friction material attached to it. This structure has a significant drawback during braking: poor heat dissipation. Under conditions such as frequent braking, high-speed braking, or long downhill stretches, the enormous heat generated by friction cannot be dissipated effectively and promptly, causing the temperature of the brake pads (especially the friction material layer) to rise sharply. When the temperature of the friction material exceeds its optimal operating range, its coefficient of friction decreases significantly (thermal fade), resulting in reduced braking torque, increased braking distance, and seriously threatening driving safety. Utility Model Content
[0004] This invention provides a heat-dissipating brake pad to overcome the deficiencies in the prior art.
[0005] This utility model is achieved through the following technical solution:
[0006] A heat-dissipating brake pad includes a backing plate and a friction pad. The backing plate is disposed on the caliper body, and the backing plate and the friction pad are bonded together by an adhesive layer. A lower strip groove is formed on one side of the backing plate facing the friction pad. The two ends of the lower strip groove extend to the two sides of the backing plate and are consistent with the direction of vehicle travel. The lower strip groove communicates with the outside. The adhesive layer is bonded to the friction pad outward along the edge of the lower strip groove.
[0007] When this application is in use, as the car is moving, the lower strip groove is set along the direction of the car's travel, so airflow can be ensured when the car is moving. As a result, the feed material can carry away the heat on the back of the friction plate when the friction plate is in motion, thereby achieving heat dissipation of the friction plate.
[0008] Preferably, the two ends of the strip groove are flared openings that are wider at the outer ends and narrower at the inner ends, and the flared openings extend to the two end faces of the back plate. The strip groove is wider at the two ends and narrower at the inner ends, which can accelerate the airflow through the middle and thus achieve better heat dissipation.
[0009] Preferably, the back plate also has a transverse upper strip groove, which is parallel to the lower strip groove and whose two ends communicate with the corresponding side flared openings. The upper strip groove can increase its overall heat dissipation area by utilizing the flared openings, thus achieving better heat dissipation.
[0010] Preferably, the back plate has a vertically fixed protrusion on one side facing the friction plate. The protrusion is located on both sides corresponding to the upper and lower strip grooves. The friction plate has a groove adapted to the protrusion. The protrusion is bonded to the groove by an adhesive layer. The protrusion increases the contact area between the adhesive layer and the friction plate, thereby compensating for the reduced bonding strength caused by the upper and lower strip grooves.
[0011] Preferably, the raised strip is a semi-circular tubular structure with a vertical strip groove extending from the back side towards the back plate. The opposite ends of the raised strip are connected to the outside, and the inner ends are connected to the corresponding upper and lower strip grooves, thereby achieving better heat dissipation while meeting the bonding strength requirements.
[0012] The beneficial effects of this utility model are as follows: the use of this application allows airflow to pass through the upper and lower strip grooves during vehicle operation, increasing heat dissipation performance and ensuring that the coefficient of friction does not decrease significantly, thereby ensuring good braking performance.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0019] A type of heat-dissipating brake pad, such as Figure 1 and Figure 2 As shown, it includes a back plate 1 and a friction plate 2. The back plate 1 is mounted on the caliper body. The back plate 1 and the friction plate 2 are bonded together by an adhesive layer 3. A lower strip groove 5 is formed on the side of the back plate 1 facing the friction plate 2. The two ends of the lower strip groove 5 extend to the two sides of the back plate 1 and are consistent with the direction of vehicle travel. The lower strip groove 5 is in communication with the outside. The adhesive layer 3 is bonded to the friction plate 2 outward along the edge of the lower strip groove 5.
[0020] When this application is in use, when the car is moving, since the lower strip groove 5 is set along the direction of the car's travel, airflow can be ensured when the car is moving. As a result, the feed can carry away the heat on the back of the friction plate 2 when the friction plate 2 is rubbing, thereby achieving heat dissipation of the friction plate 2.
[0021] The two ends of the strip groove are flared openings 6, which are wider at the outer end and narrower at the inner end, and the flared openings 6 extend to the two end faces of the back plate 1. The strip groove is wider at the two ends and narrower at the inner end, which can accelerate the airflow through the middle and thus achieve better heat dissipation.
[0022] The back plate 1 also has a transversely formed upper strip groove 4, which is parallel to the lower strip groove 5 and whose two ends are connected to the corresponding side flared openings 6. The upper strip groove 4 can increase its overall heat dissipation area by utilizing the flared openings 6, thus achieving better heat dissipation.
[0023] The back plate 1 is vertically fixedly connected to the side of the friction plate 2 with a protruding strip 7. The protruding strip 7 is located on both sides of the corresponding upper strip groove 4 and lower strip groove 5. The friction plate 2 has a groove adapted to the protruding strip 7. The protruding strip 7 is bonded to the groove through the adhesive layer 3. The protruding strip 7 is a semi-circular tubular structure and has a vertical strip groove 8 extending from the back side towards the back plate 1. The opposite ends of the protruding strip 7 are connected to the outside and the inner ends are connected to the corresponding upper strip groove 4 and lower strip groove 5.
[0024] The raised strip 7 increases the contact area between the adhesive layer 3 and the friction plate 2, thereby compensating for the reduced adhesive strength caused by the upper and lower grooves 4 and 5. The raised strip 7 has a semi-circular tubular structure and a vertical groove 8 extending from its back towards the back plate 1, thus achieving better heat dissipation while meeting the adhesive strength requirements.
[0025] The use of this application allows airflow to pass through the upper groove 4 and lower groove 5 during vehicle operation, increasing heat dissipation performance and ensuring that the coefficient of friction does not decrease significantly, thereby ensuring good braking performance.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
