Description

Technical Field

[0001] This utility model relates to the field of automotive brake technology, specifically to a composite heat dissipation brake assembly. Background Technology

[0002] Automotive brakes are a core component of vehicle safety systems, and their development is closely linked to the progress of the automotive industry. From mechanical levers to intelligent electronic controls, the evolution of brakes reflects the automotive industry's continuous pursuit of safety, efficiency, and environmental protection. In the future, with the maturity of autonomous driving and electrification technologies, braking systems will become more integrated and intelligent.

[0003] Traditional automotive brakes experience a rapid temperature rise due to frictional heat during frequent braking or heavy-load scenarios. The coefficient of friction of the brake pads decreases with increasing temperature, leading to longer braking distances and a risk of brake failure. The brake discs may crack or even break due to high-temperature expansion. High temperatures also accelerate component aging, requiring frequent replacement of brake pads and discs. During operation, the friction between the brake pads and discs generates high temperatures, especially under prolonged or frequent braking conditions, such as driving on mountain roads or high-speed emergency braking. If this heat cannot be effectively dissipated, it will lead to a decrease in braking performance, thereby affecting driving safety. Therefore, a composite heat dissipation brake assembly is designed to reduce the maximum operating temperature of the brake caliper, increase braking force during prolonged braking, and reduce braking distance to solve the above problems.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figure 1-5 A composite heat dissipation brake assembly includes a brake disc 1. The surface of the brake disc 1 has multiple heat dissipation holes 2, and the interior of the brake disc 1 has ventilation ribs 3. A bracket 4 is located on one side of the brake disc 1, and a top cover 5 is located at the upper end of the bracket 4. Friction pads 8 are located on the lower side of the top cover 5 and inside the bracket 4, and the friction pads 8 are positioned on the upper and lower sides of the brake disc 1. A caliper body 6 is located on the upper side of the top cover 5 and is connected to the friction pads 8. A cooling mechanism is located inside the bracket 4 and is connected to the interior of the friction pads 8. The heat dissipation holes 2 are evenly distributed on the surface of the brake disc 1, increasing the heat dissipation area and air convection to achieve uniform temperature distribution and increase the heat dissipation rate. The caliper body 6 and the bracket 4 are assembled together and referred to as the brake caliper assembly.

[0022] The caliper body 6 has a piston 9 inside, and the piston 9 is connected to the friction pad 8. The piston 9 pushes the friction pad 8 tightly against the surface of the brake disc 1 by hydraulic pressure. The bracket 4 has a mounting bracket 10 inside, and the friction pad 8 is set on the inner wall of the mounting bracket 10. The caliper body 6 has a piston 9 inside. When the brake fluid is pressurized, it pushes the piston 9, and the piston 9 presses the friction pad 8, thereby achieving braking.

[0023] The ventilation ribs 3 inside the brake disc 1 are radially distributed, and one end of the ventilation rib 3 is connected to the heat dissipation hole 2, while the other end extends to the outer edge of the brake disc 1. The outer edge of the brake disc 1 is provided with an air guide groove 15, which works in conjunction with the ventilation rib 3 to accelerate airflow and improve heat dissipation efficiency.

[0024] The cooling mechanism includes a shaped cooling pipe 11, which is disposed on one side of the friction plate 8 and embedded in the inner wall of the friction plate 8. The shaped cooling pipe 11 is located inside the bracket 4. One end of the shaped cooling pipe 11 is provided with a cooling pipe 12, which communicates with the shaped cooling pipe 11. A connector 13 is provided on the outer side of the cooling pipe 12, and a temperature sensor 14 is provided on one side of the friction plate 8. A groove is machined into the steel back end of the friction plate 8, in which the shaped cooling pipe 11 is installed. PG55 high-performance pure water coolant flows through the pipe, and a temperature sensor 14 is added to the friction plate 8. When the temperature is higher than the set temperature (200℃), the coolant circulates, thereby reducing the temperature of the friction plate 8.

[0025] Working principle: Passive cooling: The friction surface of the brake disc 1 has heat dissipation grooves in the same direction as the driving direction, and the friction surface of the brake disc 1 is evenly distributed with heat dissipation holes 2. During the vehicle's operation, the airflow dissipates heat and cools the vehicle. Active cooling: During the vehicle's operation, the temperature of the friction pads 8 rises due to continuous braking. When the temperature reaches 200 degrees Celsius, the temperature sensor 14 sends a signal to start the cooling system. At this time, the coolant circulates in the irregularly shaped cooling pipes 11 and 12, thereby achieving active cooling.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
