Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of braking, in particular to a brake caliper with adaptive cooling and temperature reduction. BACKGROUND

[0002] In the scenario of driving in mountainous areas, long downhill sections require frequent or long-term use of the braking system to control the vehicle speed due to continuous gravity traction. The core braking function of the braking system relies on the clamping of the caliper on the brake pad to generate braking force through friction. In this process, a large amount of friction energy is converted into heat energy. Moreover, the long downhill sections in mountainous areas often have complex road conditions, long slopes and large differences in elevation, and the braking frequency is much higher than that on regular roads, resulting in the brake pad and caliper being in a state of contact and friction for a long time, and the heat cannot be dissipated in time, which easily leads to a sharp rise in temperature.

[0003] Existing automobile braking systems mostly rely on natural air cooling or simple heat dissipation structures. In the extreme working condition of long downhill sections in mountainous areas, the heat dissipation efficiency is much lower than the heat generation rate, and the temperature of the brake pad often exceeds 300℃, and in some extreme cases, it can even reach more than 400℃. The high temperature will cause the brake pad to heat degrade, resulting in a significant decrease in the friction coefficient and weakening of the braking efficiency. This will cause the driver to be unable to accurately control the braking distance of the vehicle when driving, and in some dangerous sections, it will lead to accidents.

[0004] Therefore, the present application provides a brake caliper with adaptive cooling and temperature reduction. SUMMARY

[0050] The pushing assembly 201 comprises a sealing sheet 2010 and a first insertion column 2011, the first insertion column 2011 is inserted with the first insertion hole 20201, the first insertion column 2011 is inserted with the first insertion hole 20201 of the regulating assembly 202, and is fixed by cooperating with the screw column, so that the pushing assembly 201 and the regulating assembly 202 are firmly connected, and it is ensured that the pushing assembly 201 can stably transmit power to the regulating assembly 202, drives the regulating assembly 202 and the replacement assembly 203 to move to the brake pad 3 to realize braking, one side of the sealing sheet 2010 is attached to one side of the first brake pad 2020, and the structure such as the air duct and the flow guide cavity 2023 on the first brake pad 2020 can be sealed, so that the airflow or liquid is prevented from leaking from the attached surface, the sealing property of the heat conduction channel is ensured, and the other side of the sealing sheet 2010 is fixedly connected with a limiting column 2012, the end of the limiting column 2012 is fixedly provided with a piston sheet, the limiting column 2012 plays a connecting and guiding role, one side connects the sealing sheet 2010 with the piston sheet and transmits the power of the piston sheet, and the other side ensures the moving direction of the sealing sheet 2010 and the piston sheet to be stable when moving in the piston hole 102, so that deviation is avoided, the piston sheet moves in the piston hole 102 under the action of the oil pressure of the oil injection hole 101, converts the hydraulic energy into mechanical kinetic energy, and drives the sealing sheet 2010 and the regulating assembly 202 to move through the limiting column 2012, so as to provide power for braking.

[0051] The oil injection hole 101 is arranged on one side of the top of the clamp body 1, and the piston hole 102 is symmetrically arranged on the inner side of the clamp body 1 and communicates with the oil injection hole 101, the oil injection hole 101 is used for injecting oil into the piston hole 102 to provide hydraulic power for the movement of the piston sheet, is an input channel of braking power, the piston hole 102 is sleeved with the limiting column 2012, the end of the piston hole 102 is provided with a limiting block, the piston hole 102 provides a moving space for the piston sheet and the limiting column 2012, and cooperates with the oil injection hole 101 to form a sealed hydraulic chamber, so that the oil pressure can effectively push the piston sheet, the piston hole 102 is sleeved with the limiting column 2012, plays a guiding role in the movement of the limiting column 2012, and ensures the accuracy of the braking action, the limiting block can limit the movement stroke of the piston sheet and the limiting column 2012, prevents the piston sheet and the limiting column 2012 from being taken out of the piston hole 102, guarantees the normal work of the braking assembly 2, and avoids excessive movement to cause damage to components.

[0052] The working process of the present application is as follows: when braking is needed, the hydraulic system of the vehicle injects high-pressure oil into the piston hole 102 in the inner side of the clamp body 1 through the oil injection hole 101 on the top of the clamp body 1, the high-pressure oil acts on the piston sheet at the end of the limiting column 2012, converts the hydraulic energy into mechanical kinetic energy, pushes the piston sheet to move along the piston hole 102, and as the piston sheet moves, the limiting column 2012 drives the sealing sheet 2010 of the pushing assembly 201 to move to the regulating assembly 202.

[0053] Since the sealing sheet 2010 is fixed by the first insertion column 2011 and the first insertion hole 20201 of the first brake sheet 2020 of the control assembly 202, the thrust of the sealing sheet 2010 directly acts on the first brake sheet 2020, thereby driving the replacement assembly 203 connected with the control assembly 202 to move synchronously to the brake sheet 3 in the middle of the clamp body 1, and completing the transmission process of the braking power from hydraulic input to assembly driving.

[0054] When the control assembly 202 and the replacement assembly 203 are attached to the brake sheet 3 under the action of the thrust, the second brake sheet 2030 of the replacement assembly 203 directly contacts and rubs with the brake sheet 3, at this time, the second brake sheet 2030 is the core component of friction braking, and cooperates with the brake sheet 3 to convert the kinetic energy of the vehicle into heat energy, and the friction between the brake sheet 3 and the second brake sheet 2030 hinders the rotation of the wheel, thereby realizing the braking of the vehicle. In the process of friction braking, the connection structure of the control assembly 202 and the replacement assembly 203 guarantees the stability of braking, the first brake sheet 2020 is inserted with the second insertion hole 2033 of the second brake sheet 2030 through the second insertion column 20202, and the positioning blocks 2032 at both ends of the second brake sheet 2030 slide along the first brake sheet 2020 to limit, so that the two brake sheets always keep synchronous friction action, avoiding the braking deviation caused by the misplacement of the assembly, and ensuring the stability and reliability of the friction braking.

[0055] When the braking is in the initial stage or the braking intensity is low, the heat generated by friction is small, and the temperature-sensitive wax in the sealing cavity 2024 of the first brake sheet 2020 is in a solidified state. At this time, the solidified temperature-sensitive wax has a small volume, and the thrust on the piston plate 2026 in the sealing cavity 2024 is weak. The piston plate 2026 drives the blocking block 2027 to keep the initial position through the connecting column, the top surface of the blocking block 2027 blocks the liquid injection hole 2025 of the first brake sheet 2020, and the side surface is separated from the air inlet 2028. The blocking block 2027 is a right-angle structure, which can control the opening and closing of the liquid injection hole 2025 and the air inlet 2028 at the same time, realize the switching of the heat dissipation mode, and the connecting column connects the piston plate 2026 and the blocking block 2027 to transfer the mechanical action driven by the temperature-sensitive wax.

[0056] When the air inlet 2028 is opened, the external airflow is introduced into the first brake sheet 2020 in an orderly manner through the air guide grille 2029 on the side of the first brake sheet 2020 under the action of the vehicle driving or braking airflow, and the air flow enters the middle part of the first brake sheet 2020 as a gas flow storage and distribution space, and can be distributed to each heat conduction channel through the arc-shaped flow guide channel 2022 and flow out from the surface. In this process, the airflow carries away the heat generated by the friction between the brake assembly 2 and the brake sheet 3, realizes heat dissipation in a conventional low-temperature scene, and the airflow heat dissipation mode does not need additional liquid injection, is suitable for low-intensity braking, and can reduce the use cost.

[0057] When braking for a long time, the braking intensity increases, and the heat generated by friction significantly raises the temperature of the brake assembly 2. When the temperature reaches the liquefaction threshold of the temperature-sensitive wax, the temperature-sensitive wax in the sealed cavity 2024 is heated and liquefied and expands in volume. The expanded temperature-sensitive wax pushes the piston plate 2026 to move outward from the sealed cavity 2024. The piston plate 2026 drives the blocking block 2027 to move synchronously through the connecting column. At this time, the side surface of the blocking block 2027 blocks the air inlet 2028, and the top surface is separated from the liquid injection hole 2025, opening the liquid injection channel.

[0058] At this time, the cooling liquid in the external water tank is injected into the guide cavity 2023 through the liquid injection hole 2025. The liquid is uniformly distributed to the heat-conducting channel composed of the first ventilation channel 2021 and the second ventilation channel 2031 through the guide cavity 2023. Since the heat conduction efficiency of the liquid is much higher than that of the gas, the flowing liquid can quickly conduct away a large amount of heat generated by the friction between the brake assembly 2 and the brake pad 3, realizing rapid cooling in a high-temperature scenario. The liquid cooling mode can cope with the huge amount of heat generated by high-intensity braking, avoid brake decay caused by overheating of the brake assembly 2, and ensure brake safety in extreme scenarios. When the braking intensity decreases and the friction heat decreases, the temperature of the brake assembly 2 decreases, the temperature-sensitive wax in the sealed cavity 2024 cools and solidifies, and the volume shrinks. The piston plate 2026 drives the blocking block 2027 to return to the initial position under the action of its own restoring force, reopens the air inlet 2028, and blocks the liquid injection hole 2025. The cooling mode is switched back to air cooling, completing a self-adaptive cooling adjustment cycle.

[0059] In addition, the modular design of the replacement assembly 203 allows the second brake pad 2030 to be detachably connected with the first brake pad 2020, so that the assembly can be quickly replaced after wear, reducing maintenance costs and ensuring long-term stable operation of the caliper.
