Description

Technical Field

[0001] The present invention relates to the technical field of brake discs, and in particular to a brake disc having a heat dissipation duct optimized based on fluid mechanics. Background Art

[0002] The brake disc is one of the core components of the automobile braking system. It is usually installed on the wheel hub and used in conjunction with the brake pad. It converts the vehicle's kinetic energy into heat energy through the friction between the brake pad and the brake disc, thereby slowing down the vehicle. The brake disc with fluid mechanics optimized heat dissipation duct is a brake disc designed in combination with aerodynamic principles. Its core principle is to optimize the air duct design and guide the airflow to more effectively carry away the high temperature generated during braking, thereby increasing the service life of the brake disc. Traditional brake discs will generate a lot of heat due to friction when braking. Most of them are cooled by air to dissipate the heat generated by the brake disc, but the air cooling effect is not ideal, which will affect the service life of the brake disc in the later stage.

[0003] In order to overcome the above defects, prior art 1 (application number CN202321510471.8, Chinese patent with application date of 2023-06-14) is a new type of brake disc, in which inner / outer brake discs of unequal thickness are adopted, the inner / outer brake discs are connected by a petal-type connection part, and the connection strength of the inner / outer brake discs is ensured by setting cylindrical reinforcement ribs and rectangular reinforcement ribs, while uniform heat dissipation during braking effectively solves the thermal cracking phenomenon caused by uneven heat dissipation during braking; secondly, the rectangular grooves of the inner / outer brake discs are used to collect fine particles during braking, thereby avoiding abnormal wear and abrasion failures on the inner / outer brake disc surfaces, and prior art 2 (application number CN20 1820285924.4, Chinese patent application date: 2018-02-28) brake disc, a heat dissipation hole is set from the outside of the braking part to the inside of the mounting part, that is, a hole is punched in the friction area of ​​the brake disc, and the heat dissipation hole is a conical hole with a larger outside and a smaller inside. The hole diameter is larger at the position where the external friction force is larger, and the heat dissipation area is larger; the friction force on the mounting part is small, and the hole diameter is correspondingly small, and the position of the heat dissipation hole at the mounting part is actually the connection between the mounting part and the braking part. The small hole diameter can enhance the structural strength of the connection and the whole. Therefore, the conical heat dissipation hole is cleverly set and reasonably structured, which can effectively increase the heat dissipation area of ​​the brake disc, improve the thermal performance of the brake disc, reduce the temperature of the brake disc during continuous braking, and increase the service life of the brake disc.

[0004] Although the existing technology can improve the heat dissipation and ventilation efficiency of the brake disc, thereby improving the heat dissipation and ventilation effect of the brake disc, when the brake disc is dissipating heat and cooling, debris will easily appear due to the friction between the brake pad and the brake disc. The generated debris will shorten the service life of the brake disc due to long-term friction. There is no debris removal mechanism to remove and clean the generated debris, and the practicality is poor. Therefore, a brake disc with a heat dissipation duct optimized based on fluid mechanics is proposed to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to provide a brake disc with a heat dissipation duct optimized based on fluid mechanics, so as to solve the problem raised by the above background technology that in the current market, when the brake disc is cooling down, debris will easily appear due to the friction between the brake pad and the brake disc, and the generated debris will shorten the service life of the brake disc due to long-term friction, and there is no debris removal mechanism to remove and clean the generated debris, resulting in poor practicality.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a brake disc for optimizing a heat dissipation duct based on fluid mechanics, comprising an inner disc body and a flange disc arranged inside the inner disc body, and the rear end of the flange disc extends through and extends to the rear end outside of the inner disc body, and a circle of positioning hole grooves is provided on the surface of the flange disc, the front side of the inner disc body is connected to the outer disc body, and the inner disc body and the outer disc body have the same diameter, the front side surface of the outer disc body is provided with a circle of heat dissipation holes, and the circle of heat dissipation holes are arranged at equal angles, and the outer surface of the outer disc body is also provided with a circle of heat dissipation fins at equal angles, the front surface of the outer disc body is provided with a circle of guide arc grooves, and each guide arc groove is in an arc shape, and the guide arc groove and the heat dissipation through holes are arranged correspondingly, the rear side of the outer disc body is symmetrically provided with limit rods, and the two limit rods have the same structure, and the rear ends of the two limit rods extend through and extend to the interior of the inner disc body, the rear side surface of the outer disc body is provided with a slide groove, and a heat sink is slidably installed inside the slide groove.

[0007] Preferably, a cleaning disk is installed on the rear side of the heat sink, and the outer side surface of the cleaning disk is closely connected to the inner disk body.

[0008] Preferably, a tension spring is installed on the rear side of the outer disk body, and a side of the tension spring close to the heat sink is connected to the heat sink.

[0009] Preferably, mounting blocks are symmetrically mounted on the rear side of the outer disk body, and the two mounting blocks have the same structure, and the rear ends of the two mounting blocks extend through and extend to the upper and lower sides of the inner disk body.

[0010] Preferably, the interior of the installation block is symmetrically penetrated by a sliding installation limit block, and the two limit blocks extend through one side close to the inner disk body to the interior of the inner disk body, and the two limit blocks are inclined.

[0011] Preferably, a second return spring is arranged inside the mounting block, and both ends of the second return spring are connected to limit blocks.

[0012] Preferably, a toggle rod is slidably mounted on the top of the inner disk body via a first return spring, and both ends of the bottom of the toggle rod are in arc shape, and two limit blocks are correspondingly arranged at both ends of the bottom of the toggle rod.

[0013] Preferably, the inner disk body is slidably mounted with a top plate, and a mounting block corresponds to a side of the top plate close to the mounting block, and an extrusion rod is rotatably mounted on the front side of the top plate, and the front ends of the two extrusion rods are rotatably connected to movable seats, and the two movable seats are slidably mounted inside the inner disk body.

[0014] Preferably, two extrusion springs are arranged inside the inner disk body, and the two extrusion springs have the same structure, and one end of the two extrusion springs close to the moving seat is connected to the moving seat.

[0015] Compared with the prior art, the invention has the following beneficial effects: the heat dissipation seat can be used to dissipate heat more evenly on the outer disc body generated by friction, thereby preventing heat from accumulating inside the outer disc body and affecting the service life of the outer disc body in the later stage; the mobile heat dissipation seat can also drive the cleaning disc to move and clean the debris and impurities stuck on the surface of the inner disc body, thereby preventing the impurities and debris from sticking to the surface of the inner disc body and affecting the braking friction of the brake pad in the later stage; the invention has better practicality: (1) A heat sink is provided, which is installed by sliding a groove on the inner side of the outer disc body and then slidingly installed in the groove through a tension spring. When the wheel hub drives the inner disc body and the outer disc body to rotate, the centrifugal force of the rotation of the outer disc body drives the heat sink to slide in the groove to dissipate heat. The heat sink can be moved to dissipate heat from the outer disc body that generates heat, thereby preventing heat from accumulating in the inner side of the outer disc body and affecting the subsequent braking use. The service life of the outer disc body can also be increased, and the practicality is better.

[0016] (2) Furthermore, when the brake pads are performing friction braking on the outer disc, the tension spring will reset the heat sink that is displaced by centrifugal force through its own elastic force, and the heat sink that is reset can also be used to cool the outer disc of the friction brake, which can effectively increase the heat dissipation area of ​​the outer disc, improve the heat dissipation performance of the outer disc, and increase the service life of the outer disc.

[0017] (3) A flow guiding arc groove and a heat dissipation through hole are provided. A circle of flow guiding arc grooves are provided at equal angles on the surface of the outer disk body. The heat generating outer disk body can be cooled more evenly through a circle of flow guiding arc grooves. Then, a circle of heat dissipation through holes can also improve the heat dissipation cooling of the outer disk body, thereby expanding the overall heat dissipation area of ​​the outer disk body and improving practicality.

[0018] (4) A limit block is set, and mounting blocks are installed on the upper and lower sides of the rear end of the outer disc body, and then mounting blocks are slidably installed on both sides of the inner parts of the two mounting blocks. When the inner disc body and the outer disc body need to be quickly positioned and installed, the outer disc body only needs to drive the two limit blocks to shrink and move through the extrusion of the inner disc body, and then the two limit blocks can be automatically popped out to the inside of the inner disc body through the elastic force of the second return spring itself, so that the position of the outer disc body after installation can be limited and fixed, avoiding the phenomenon of loosening and falling off of the outer disc body during braking in the later stage, thereby improving the stability of the outer disc body.

[0019] (5) Furthermore, when it is necessary to perform a quick auxiliary disassembly process on the outer disk body, the toggle rod is pulled to squeeze the two limit blocks through the two first reset springs to retract and move, so that the two limit blocks retract and move to the inside of the mounting block, so that the outer disk body and the inner disk body can be quickly disassembled. During the quick disassembly process of the outer disk body and the inner disk body, the two squeeze springs will elastically reset the two squeezed moving seats through their own elastic force, so that the two moving seats can drive the two moving seats to drive the top plate to squeeze and discharge the mounting block, thereby realizing quick auxiliary disassembly of the outer disk body, improving the disassembly efficiency of the outer disk body, and improving practicality.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The present invention provides the following technical solution, a brake disc with optimized heat dissipation duct based on fluid mechanics: Embodiment 1, in order to solve the problem that when the brake disc is cooled, debris is easily generated due to the friction between the brake pad and the brake disc, and the generated debris will shorten the service life of the brake disc due to long-term friction, and no debris removal mechanism is provided to remove and clean the generated debris, which will also affect the heat dissipation effect of the brake disc in the later stage, and the practicality is poor, the following is disclosed: an inner disc body 1, and a flange 2 arranged inside the inner disc body 1, and the rear end of the flange 2 extends through and extends to the rear end outside of the inner disc body 1, and a circle of positioning holes 18 is provided on the surface of the flange 2, the front side of the inner disc body 1 is connected to the outer disc body 3, and the inner disc body 1 and the outer disc body 3 are connected to each other. The diameters of the disk bodies 3 are the same, a circle of heat dissipation holes 6 are provided on the front side of the outer disk body 3, and the circle of heat dissipation holes 6 are arranged at equal angles, a circle of heat dissipation fins 4 are also installed on the outer surface of the outer disk body 3 at equal angles, a circle of guide arc grooves 5 are provided on the front surface of the outer disk body 3, and each guide arc groove 5 is in an arc shape, and the guide arc groove 5 and the heat dissipation holes 6 are arranged correspondingly, a limit rod 8 is symmetrically installed on the rear side of the outer disk body 3, and the two limit rods 8 have the same structure, and the rear ends of the two limit rods 8 extend through and extend to the interior of the inner disk body 1, a slide groove 9 is provided on the rear side of the outer disk body 3, and a heat sink 10 is slidably installed inside the slide groove 9.

[0024] A cleaning disk 11 is installed on the rear side of the heat sink 10, and the outer side of the cleaning disk 11 is closely connected to the inner disk body 1. A tension spring 12 is installed on the rear side of the outer disk body 3, and the tension spring 12 is connected to the heat sink 10 on the side close to the heat sink 10.

[0025] like Figure 1-Figure 5 As shown, when the brake disc cooperates with the brake pad to brake, the outer disc body 3 generated by friction can be ventilated and cooled through a circle of heat dissipation holes 6 opened on the surface of the outer disc body 3, and then the overall heat dissipation range of the outer disc body 3 can be expanded through a circle of arc-shaped guide arc grooves 5, thereby better improving the heat dissipation and cooling efficiency of the outer disc body 3. At the same time, a circle of heat dissipation fins 4 arranged on the surface of the outer disc body 3 can also dissipate heat and cool the outer disc body 3 that generates heat through heat conduction, thereby improving practicality.

[0026] When the wheel hub of the automobile drives the brake disc to travel, the centrifugal force of the rotation of the outer disc body 3 will simultaneously drive the heat sink 10 to slide on the inner side of the slide groove 9, that is, the heat sink 10 can be ventilated and dissipated while the heat sink 10 is moving centrifugally, so as to avoid the heat accumulation inside the outer disc body 3 and affecting the service life of the outer disc body 3 in the later stage, which can effectively increase the heat dissipation area of ​​the outer disc body 3, improve the heat dissipation performance of the outer disc body 3, and increase the service life of the outer disc body 3. When the heat sink 10 is moved by the centrifugal force, it will also drive the cleaning disc 11 to move and clean the debris and impurities on the surface of the inner disc body 1, so as to avoid the impurities and debris sticking to the surface of the inner disc body 1 and affecting the braking cooling efficiency in the later stage. Finally, when the brake pad performs friction braking on the brake disc, the tension spring 12 will elastically reset the position of the heat sink 10 after moving by its own elastic force, and can also repeatedly dissipate heat and cool the outer disc body 3 by resetting the moving heat sink 10, so as to be recycled in the later stage, which is more practical.

[0027] Embodiment 2 is different from Embodiment 1 in that the outer disc body 3 can be quickly disassembled and installed to improve the installation and disassembly efficiency of the brake disc, and the operation is more time-saving and labor-saving. A mounting block 13 is symmetrically installed on the rear side of the outer disk body 3, and the two mounting blocks 13 have the same structure, and the rear ends of the two mounting blocks 13 extend through the upper and lower sides of the inner disk body 1, and the interior of the mounting block 13 is symmetrically penetrated by a sliding limit block 14, and the two limit blocks 14 extend through the side close to the inner disk body 1 to the interior of the inner disk body 1, and the two limit blocks 14 are inclined in shape, and a second return spring 17 is arranged inside the mounting block 13, and the two ends of the second return spring 17 are connected to the limit block 14, and a toggle rod 7 is slidably installed on the top of the inner disk body 1 through a first return spring 16, and the bottom ends of the toggle rod 7 are in an arc shape, and there are two limit blocks 14 at the two ends of the bottom of the toggle rod 7.

[0028] like Figure 1-Figure 10 As shown, when it is necessary to quickly position and install the outer disk body 3, it is only necessary to extend the outer disk body 3 through the two limit rods 8 to the inner sides of the inner disk body 1. At this time, the two installation blocks 13 will simultaneously drive the two limit blocks 14 to shrink and move through the extrusion of the inner disk body 1, so that the two limit blocks 14 shrink and move to the inside of the installation blocks 13. At this time, the second return spring 17 will automatically pop out the limit blocks 14 into the inner disk body 1 through its own elastic force after squeezing and shrinking, so that the position of the outer disk body 3 after installation can be limited and fixed, avoiding the loosening and falling off of the outer disk body 3 during braking in the later stage, and having better stability.

[0029] Embodiment 3 is different from Embodiment 2 in that the auxiliary disassembly mechanism can be provided to assist in the quick disassembly of the outer plate 3, which is more practical and discloses: The inner disk body 1 is slidably mounted with a top plate 15, and a side of the top plate 15 close to the mounting block 13 corresponds to the mounting block 13, and an extrusion rod 19 is rotatably mounted on the front side of the top plate 15, and the front ends of the two extrusion rods 19 are rotatably connected to a moving seat 20, and the two moving seats 20 are slidably mounted inside the inner disk body 1, and two extrusion springs 21 are arranged inside the inner disk body 1, and the two extrusion springs 21 have the same structure, and one end of the two extrusion springs 21 close to the moving seat 20 is connected to the moving seat 20.

[0030] When the outer disk body 3 needs to be quickly disassembled and replaced, it is only necessary to pull the toggle rod 7 to squeeze the two inclined limit blocks 14 through the first return spring 16 to retract and move them. When the two limit blocks 14 retract and move to the installation block 13, the outer disk body 3 can be quickly disassembled and replaced, and the operation is more time-saving and labor-saving.

[0031] like Figure 1-Figure 11 As shown, while the outer disk body 3 is positioned and installed, the mounting block 13 will simultaneously squeeze the top plate 15 to drive the two squeezing rods 19 to drive the two moving seats 20 to expand and move. At this time, the two squeezing springs 21 will accumulate force through the squeezing of the two moving seats 20. Then, during the disassembly and replacement of the outer disk body 3, the two squeezing springs 21 will elastically reset the position of the moving seats 20 after squeezing and moving through their own elastic force. At this time, the two reset moving seats 20 will simultaneously drive the squeezing rods 19 to drive the top plate 15 to automatically push and pop out the mounting block 13, so that the outer disk body 3 can be quickly and auxiliaryly disassembled, which improves the disassembly efficiency of the outer disk body 3, thereby completing a series of tasks.

[0032] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
