Description

Technical Field

[0001] This application relates to the field of automotive brakes, and more specifically, to a brake pad for an automotive disc brake. Background Technology

[0002] Brake pads used in automotive disc brakes are the standard name for "disc brake pads," commonly known as "brake pads." They are the core friction components in a disc braking system that directly rub against the brake disc, converting the vehicle's kinetic energy into heat energy to achieve deceleration or stopping. They are essentially the friction consumables of the braking system and need to be installed on the inside of the car's wheels in conjunction with the brake disc, brake caliper assembly, and wheel hub assembly to achieve the braking effect.

[0003] Currently, the structure of existing products can be referenced from a disc brake for real-time monitoring of brake pad temperature field disclosed in Chinese patent document CN119934173A. The temperature of the brake pads is transmitted through the temperature-conducting plate, and the fiber optic grating temperature sensor senses the temperature of the temperature-conducting plate, thereby monitoring the temperature distribution of the brake pads. Furthermore, since the fiber optic grating temperature sensor is embedded in the inner wall of the first and second bridge bodies, when the brake pads need to be replaced, the fiber optic grating temperature sensor does not need to be replaced at the same time, thus saving costs. The structure is relatively simple and easy to maintain.

[0004] In the above structure, since the fiber Brake grating temperature sensor is embedded in the inner wall of the first and second bridge bodies, when the brake pads need to be replaced, the fiber Brake grating temperature sensor does not need to be replaced at the same time, thus saving costs. The structure is relatively simple and easy to maintain. However, in actual application, the friction between the brake pads will generate local high temperatures and a large amount of dust. The traditional brake caliper assembly lacks a structure to handle the dust, which will affect the subsequent braking effect. At the same time, a large amount of dust will also affect the heat dissipation of the brake disc itself, thus affecting the heat fade problem.

[0005] Currently, there is no automotive disc brake pad that can promptly blow away the large amount of dust generated by the friction between the brake pads and brake discs, optimize the heat dissipation of the brake discs, and address the issues of brake performance degradation and dust accumulation after wading through water via a cleaning module.

[0012] Furthermore, the eddy current module includes a chuck, eddy current blades, rotating beads, anti-wear beads, a retaining groove, and a threaded hole. The chuck is provided with eddy current blades inside. A rotating bead is embedded in the inner side of the outer end of the chuck in an annular shape.

[0013] Furthermore, the chuck is composed of two parts, front and back. The contact ends on the inner sides of the two chucks are provided with interlocking retaining grooves.

[0019] The eddy current module, connected to the flange via a connecting module and secured with bolts, rotates inside the guide module when the flange is driven by the wheel. This draws in external air through the lower intake pipe of the guide module, where it is then driven by the eddy current blades to form a directional, high-speed eddy current. This eddy current is then transported upwards, exiting the guide module through the exhaust pipe, and then fed through the air supply pipe into the exhaust nozzle mounted on the upper part of the brake caliper assembly. From there, the eddy current is injected into the lower part of the brake caliper assembly. The air jets blow air onto the inner side of the brake pads and the contact area of ​​the brake disc, removing a large amount of dust generated during braking and reducing its impact on subsequent braking. At the same time, they also provide an active cooling effect on the brake disc, improving heat dissipation efficiency and smoothing out temperature peaks. The vortexes discharged from the air jets enter the cleaning module and are transported to the arc-shaped tube through the connecting pipe. They are then sprayed out by the symmetrically distributed cleaning nozzles on both sides, contacting the brake discs and cleaning the debris adhering to them. This provides active cleaning and protection, improving stability and cleanliness under harsh operating conditions. Attached Figure Description

[0028] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] As a preferred embodiment of this example, Figures 1 to 7As shown, a brake pad for an automotive disc brake includes a brake disc 1. A flange 2 is reinforced to the inner side of the right end of the brake disc 1 by flange bolts. A drive shaft 3 is provided in the middle of the right end of the flange 2. A hub assembly 4 is provided on the right side of the outer end of the drive shaft 3. A flow guiding module 5 is provided at the front end of the hub assembly 4. A vortex module 6 is provided on the inner side of the front end of the flow guiding module 5. A connecting module 7 is provided at the front end of the vortex module 6. A brake caliper assembly 8 is provided above the outer end of the brake disc 1. A cleaning module 9 is provided on the left side of the outer end of the flow guiding module 5. An air supply pipe 10 connects the flow guiding module 5 and the brake caliper assembly 8.

[0030] Flange 2 secures brake disc 1 to the inner side of the wheel using flange bolts. Drive shaft 3 is welded to flange 2 as a single unit. The front end of drive shaft 3 passes through the middle of the inner side of connecting module 7, eddy current module 6, guide module 5, and wheel hub assembly 4. Drive shaft 3 and wheel hub assembly 4 are connected via a spline connection. This spline connection is a known existing technology and will not be elaborated upon further in this paper. Guide module 5 is reinforced with bolts to wheel hub assembly 4. The guide module 5 and eddy current module... The modules 6 are interconnected. The eddy current module 6 and the connecting module 7 are reinforced with bolts. The contact end of the connecting module 7 and the flange 2 is also reinforced with bolts. Air outlets are installed on the front and rear sides of the upper end of the brake caliper assembly 8. The brake caliper assembly 8 is a known technology and will not be described in detail in this paper. The cleaning module 9 and the flow guiding module 5 are interconnected and their contact ends are reinforced with bolts. The air supply pipe 10 is used to connect the air outlet pipe 504 at the upper end of the flow guiding module 5 and the air outlets installed on the front and rear sides of the upper end of the brake caliper assembly 8.

[0031] During operation, the eddy current module 6, which is connected to the flange 2 via the connecting module 7 and reinforced with bolts, rotates inside the guide module 5 when the flange 2 is driven by the wheel. This draws in external air through the lower air intake pipe 503 of the guide module 5. Then, driven by the eddy current blades 602 inside the eddy current module 6, a directional high-speed eddy current is formed. This eddy current is then transported upwards and discharged from the guide module 5 through the air outlet pipe 504. After being transported through the air supply pipe 10, it enters the air outlet installed on the upper end of the brake caliper assembly 8. The air outlet injects the eddy current into the inner side of the lower end of the brake caliper assembly 8, blowing it towards the contact area between the brake pads and the brake disc 1. This blows away a large amount of dust generated during braking, reducing the impact on subsequent braking. At the same time, it also provides an active cooling effect on the brake disc 1, improving heat dissipation efficiency and smoothing out temperature peaks.

[0032] like Figures 3 to 6As shown, in this embodiment, the wheel hub assembly 4 includes a triangular arm 401, an extension sleeve 402, and a reinforcing hole 403. The extension sleeve 402 is provided at the middle of the front end of the triangular arm 401. The triangular arm 401 and the extension sleeve 402 are integrated. The reinforcing hole 403 is provided on the outer side of the front end of the extension sleeve 402. The reinforcing holes 403 are distributed in a ring symmetrical manner.

[0033] By using the extension sleeve 402 and the reinforcing hole 403, the triangular arm 401 can be connected and reinforced with the flow guide module 5 so that during subsequent operation, the flow guide module 5 itself will not rotate with the rotation of the flange 2, and will remain in a sleeve structure with the vortex module 6, so that the rotation of the vortex module 6 can be used to draw external air into the flow guide module 5 to form a vortex.

[0034] like Figures 5 to 7 As shown, in this embodiment, the flow guiding module 5 includes a flow guiding shroud 501, a fixing pipe 502, an air inlet pipe 503, an air outlet pipe 504, and an air inlet pipe 505. The fixing pipe 502 is provided on the rear side of the outer end of the flow guiding shroud 501. The air inlet pipe 503 is connected to the lower part of the outer end of the flow guiding shroud 501, the air outlet pipe 504 is connected to the upper part of the outer end of the flow guiding shroud 501, and the air inlet pipe 505 is connected to the left side of the outer end of the flow guiding shroud 501. The vortex module 6 includes a chuck 601, vortex blades 602, rotating beads 603, anti-wear beads 604, a retaining groove 605, and a threaded hole 606. The chuck 601 is provided with vortex blades inside. The chuck 601 has a rotating bead 603 embedded in the inner side of its outer end, an anti-wear bead 604 embedded in the rear end of its rear end, a retaining groove 605 annularly formed on the inner contact end of its inner side, and a threaded hole 606 annularly formed on the front end of its front end. The connecting module 7 includes a connecting sleeve 701, a mating ring 702, a mating bolt 703, and a connecting bolt 704. The mating ring 702 is provided on the outer side of the rear end of the connecting sleeve 701. The mating bolts 703 are distributed in an annular pattern on the front side of the outer end of the mating ring 702, and the connecting bolts 704 are distributed in an annular pattern on the rear side of the outer end of the connecting sleeve 701.

[0035] The flow deflector 501 is integrated with the fixed pipe 502, air inlet pipe 503, air outlet pipe 504, and air inlet pipe 505. The air inlet pipe 503, air outlet pipe 504, and air inlet pipe 505 are interconnected with the interior of the flow deflector 501. A filter screen is threaded onto the front end of the air inlet pipe 503, and a pipe connector is connected to the upper end of the air outlet pipe 504. The air inlet pipe 505 and the cleaning module 9 are connected and sealed at their contact points. The chuck 601 consists of two parts, front and rear. The vortex blade 602 and the inner side of the front chuck 601 are integrated, and the rear chuck 601 is reinforced with welding to the vortex blade 602, making the two chucks 601 and the vortex blade 602 a single unit. The inner contact end of the chuck 601 is provided with a retaining groove 605 that engages with each other. Furthermore, the outer ends of both the front and rear chucks 601 are circumferentially embedded with rotating beads 603. Anti-wear beads 604 are embedded in the inner rear end of the rear chuck 601 and distributed at an annular symmetrical angle. Threaded holes 606 are circumferentially symmetrically opened at the inner front end of the front chuck 601. The connecting sleeve 701 and the mating ring 702 are integrated into a single structure. The mating bolts 703 are circumferentially symmetrically distributed. The front thread of the mating bolt 703 penetrates the interior of the mating ring 702 and extends to the rear outer side. The connecting bolts 704 are circumferentially symmetrically distributed. The front thread of the connecting bolt 704 penetrates the interior of the outer structure of the front end of the connecting sleeve 701 and continues to extend to the front outer side.

[0036] A vortex wheel is formed by the chuck 601 and the vortex blades 602. The vortex wheel and flange 2 are then connected as a whole by the connecting module 7. When the flange 2 is rotated by the wheel, the power is transmitted to the vortex wheel, causing it to rotate inside the guide shroud 501 in the guide module 5. Simultaneously, because rotating beads 603 are annularly embedded at the outer ends of both the front and rear chucks 601, and anti-wear beads 604 are embedded on the inner rear end of the rear chuck 601, the vortex wheel is not disturbed when rotating inside the guide shroud 501. When the vortex wheel rotates at high speed, it draws external air into the guide shroud 5 through the air intake pipe 503 connected to the lower end of the guide module 5. Inside 01, a directional high-speed vortex is formed under the drive of the vortex blades 602 inside the vortex module 6. The vortex is then transported upwards. The vortex discharged from the air outlet pipe 504 is transported through the air supply pipe 10 and enters the air outlet installed on the upper end of the brake caliper assembly 8. The air outlet injects the vortex into the inner side of the lower end of the brake caliper assembly 8 and blows it towards the contact area of ​​the brake pads and brake disc 1, blowing off a large amount of dust generated by braking and reducing the impact on subsequent braking. At the same time, it also has an active cooling effect on the brake disc 1, improving heat dissipation efficiency and suppressing temperature peaks. The vortex discharged from the air inlet pipe 505 enters the cleaning module 9 for cleaning.

[0037] like Figure 1 and Figure 7 As shown, in this embodiment, the cleaning module 9 includes a connecting pipe 901, a splicing plate 902, an arc-shaped pipe 903, and cleaning nozzles 904. The upper end of the connecting pipe 901 is provided with the splicing plate 902, the lower left side of the connecting pipe 901 is provided with the arc-shaped pipe 903, and the upper left and right sides of the arc-shaped pipe 903 are provided with cleaning nozzles 904. The connecting pipe 901, the splicing plate 902, and the arc-shaped pipe 903 are integrated into one structure, and the interiors of the connecting pipe 901 and the arc-shaped pipe 903 are interconnected. The cleaning nozzles 904 are symmetrically distributed from left to right.

[0038] By using the splicing plate 902, the connecting pipe 901 is spliced ​​with the air inlet pipe 505 at the lower end of the guide shroud 501. Then, when the vortex module 6 generates vortices inside the guide shroud 501 and delivers them to the air inlet pipe 505, the vortexes can be delivered to the arc-shaped pipe 903 through the connecting pipe 901. They are then sprayed out through the symmetrically distributed cleaning nozzles 904 and come into contact with the brake disc 1 from both sides to clean the debris adhering to the brake disc 1, achieving the effect of active cleaning and protection, and improving stability and cleanliness under harsh working conditions.

[0039] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
