Description

Technical Field

[0001] This utility model belongs to the field of caliper technology, specifically relating to a brake caliper with heat dissipation function. Background Technology

[0002] A caliper is a component that applies force to the brake disc. It is a type of clamp device that functions to slow down, stop, or maintain a stopped state of the moving wheel. It is usually used in disc brake systems. It mainly receives hydraulic pressure from the master cylinder through the brake lines and then applies the hydraulic pressure to the piston inside the caliper. The piston then pushes the brake pads, causing the brake pads to engage with the brake disc. The friction between them slows down the vehicle. During braking, the brake caliper generates a lot of heat due to the friction between the brake pads and the brake disc. If this heat cannot be dissipated in time, it will lead to a decrease in the performance of the braking system and may even cause safety problems. The heat dissipation problem of the braking system is particularly prominent, especially in high-performance vehicles or under long-term continuous braking.

[0003] Traditional heat dissipation methods mainly rely on the heat conduction of the brake disc itself and natural convection. However, this method has relatively low heat dissipation efficiency. Especially when driving at high speed or braking continuously, the temperature of the brake disc and brake pads will rise rapidly, leading to a decrease in braking performance and potentially causing brake failure in severe cases. Utility Model Content

[0004] The purpose of this invention is to provide a brake caliper with heat dissipation function that assists in heat dissipation of brake pads and brake discs in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A brake caliper with heat dissipation function includes two caliper bodies and a conduit disposed between the caliper bodies. The caliper bodies have cavities inside, which are connected by the conduit. A piston is slidably disposed on the caliper body through the cavity. Multiple locking pins are connected between the caliper bodies.

[0007] It also includes:

[0008] Brake pads, there are two brake pads, the brake pads are arranged in a relative manner between the caliper bodies by means of locking pins;

[0009] A heat sink is provided on the brake pad to dissipate heat from the brake pad.

[0010] A guide tube is provided on the outer surface of the caliper body, and guides the air to the brake disc behind the caliper body.

[0011] As a further optimization of this utility model, a brake pad is provided on the side of the brake pad away from the caliper body, a connecting platform is provided on the side of the brake pad close to the caliper body, and a heat sink is arranged around the connecting platform on the brake pad.

[0012] As a further optimization of this utility model, an air inlet is provided at one end of the guide pipe, an air outlet is provided at the other end of the guide pipe, a guide surface is provided inside the guide pipe, the guide surface is an inclined surface, and the end of the guide surface near the air inlet is higher than the end of the air outlet.

[0013] As a further optimization of this utility model, the caliper body is provided with a receiving groove, the heat sink can be accommodated in the receiving groove, and the piston is disposed in the receiving groove.

[0014] As a further optimization of this utility model, the piston is connected to the brake pads via a connecting platform, and an elastic element is provided between the brake pads.

[0015] As a further optimization of this utility model, the air inlet faces the front of the vehicle.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. Unlike existing technologies, by installing heat sinks on the brake pads during actual use, the heat dissipation efficiency of the braking system can be significantly improved. The heat sinks can effectively conduct heat away from the brake pads and carry away the heat through air convection, thereby reducing the temperature of the braking system.

[0018] 2. Unlike existing technologies, in actual use, by setting up a guide pipe, external airflow can be guided to blow onto the brake disc to assist in heat dissipation. The guide surface design inside the guide pipe allows the airflow to be discharged obliquely downwards, better covering the surface of the brake disc and improving the heat dissipation effect.

[0019] 3. Unlike existing technologies, in actual use, by opening a receiving groove on the caliper body, the heat sink can be stored in it when the brake pads are reset, preventing dirt and other debris from getting into the gaps between the heat sinks during vehicle operation and affecting the heat dissipation effect.

[0027] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0028] like Figure 1 - Figure 6 The diagram illustrates a brake caliper with a heat dissipation function, comprising two caliper bodies 1 and a conduit 3 disposed between the caliper bodies 1. Each caliper body 1 has an internal cavity connected by the conduit 3. A piston 8 is slidably disposed within the cavity of each caliper body 1. Multiple locking pins 7 connect the caliper bodies 1. The caliper caliper also includes two brake pads 5 disposed opposite each other between the caliper bodies 1 via the locking pins 7, heat dissipation fins 6 disposed on the brake pads 5 for heat dissipation, and a guide pipe 2 disposed on the outer surface of the caliper body 1 for guiding airflow to the brake disc behind the caliper body 1.

[0029] A brake pad 51 is provided on the side of the brake pad 5 away from the caliper body 1, and a connecting platform 52 is provided on the side of the brake pad 5 close to the caliper body 1. A heat sink 6 is provided around the connecting platform 52 on the brake pad 5. The replaceable brake pad 51 prevents the brake pad 5 from being excessively damaged. The connecting platform 52 is the platform through which the brake pad 5 contacts the piston 8.

[0030] One end of the guide pipe 2 has an air inlet 21, and the other end has an air outlet 22. The guide pipe 2 has a guide surface 23 inside, which is an inclined surface. The end of the guide surface 23 that is closer to the air inlet 21 and higher than the end of the air outlet 22 allows air to enter through the air inlet 21 and exit through the air outlet 22. At the same time, due to the inclined surface of the guide surface 23, the airflow is discharged obliquely downward and blown towards the brake disc. Thus, during the braking process, the brake disc, which is blocked by the caliper body 1, still has a certain amount of airflow blowing towards its surface to assist in the cooling of the brake disc.

[0031] The caliper body 1 has a receiving groove 4, in which the heat sink 6 can be accommodated. The piston 8 is set in the receiving groove 4. The heat sink 6 is stored in the receiving groove 4 to avoid too much dirt getting stuck in the gaps of the heat sink 6 during vehicle operation, which would affect the heat dissipation effect of the heat sink 6.

[0032] The piston 8 is connected to the brake pad 5 through the connecting platform 52. An elastic element 9 is provided between the brake pads 5. The connecting platform 52 prevents the piston 8 from directly contacting the heat sink 6, thus preventing the heat sink 6 from being deformed by the piston 8.

[0033] The air inlet 21 faces the front of the vehicle, ensuring sufficient airflow in the guide pipe 2.

[0034] It should be noted that this type of brake caliper with heat dissipation function works by pressing the brake pedal, which allows brake fluid to be delivered to the caliper body 1 through the conduit 3 and pushes the piston 8. This causes the two brake pads 5 to squeeze the brake disc, thereby applying the brakes. When the brake pads 5 rub against the brake disc, the heat generated on the brake pads 5 is conducted through the heat dissipation fins 6. During the braking process, the electric vehicle will still move forward for a certain distance. During this movement, the air intake pipe 2 draws in air through the air inlet 21 and discharges it through the air outlet 22. At the same time, due to the inclined surface of the air guide surface 23, the airflow is discharged obliquely downward and blows towards the brake disc. Thus, during the braking process, a certain amount of airflow is still blown onto the surface of the brake disc, which is blocked by the caliper body 1, to assist in the heat dissipation of the brake disc.

[0035] After braking stops, the brake pad 5 is reset by the elastic element 9 and re-embedded in the receiving groove 4. The receiving groove 4 stores the heat sink 6, thereby preventing too much dirt from getting stuck in the gaps of the heat sink 6 during vehicle operation, which would affect the heat dissipation effect of the heat sink 6.

[0036] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
