Description

Technical Field

[0001] The invention belongs to the technical field of brake discs, and in particular relates to a brake disc and a brake disc manufacturing process. Background Art

[0002] The brake disc, in simple terms, is a round plate that rotates when the car is moving. The brake caliper clamps the brake disc to generate braking force. When you step on the brake, it clamps the brake disc to slow down or stop the car. The brake disc has a good braking effect and is easier to maintain than drum brakes.

[0003] However, the conventional device still has the following problems when used: The patent application publication number is CN118423389B, which discloses a lightweight brake disc and a brake disc manufacturing process. The exhaust volume of the air duct can be adaptively distributed through a cooling box and a movable plate. When the temperature of the brake disc is high, the linkage arms on both sides drive the swing guide plate to swing outward. At this time, most of the air volume is discharged through the air duct containing the cooling box. This structure is stable and effective and improves the cooling efficiency.

[0004] In actual use, when the driver brakes suddenly, the rotating brake disc will brake suddenly, and the contact area and friction between the brake pad and the brake disc will increase rapidly, thereby accelerating the wear of the brake pad and the brake disc.

DETAILED DESCRIPTION

[0034] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit 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.

[0035] For example, see Figures 1 to 16 The present invention provides a brake disc and a brake disc manufacturing process technical solution: it includes a brake disc body 1, the outer wall at the top of the brake disc body 1 is provided with a T-shaped groove 17, the inside of the T-shaped groove 17 is fixedly connected with a fixing rod 2, the inside of the T-shaped groove 17 is rotatably connected with an upper disc body 12, the outer wall at the bottom of the upper disc body 12 is fixedly connected with a movable rod 21, the outer walls of multiple movable rods 21 are slidably connected with the inside of the T-shaped groove 17, the outer walls on one side of multiple fixed rods 2 are provided with a buffer mechanism, the outer wall of the brake disc body 1 is provided with an air duct 11, the upper part of the air duct 11 is provided with a first air hole 13, the outer wall of the top of the first air hole 13 is connected through the inside of the T-shaped groove 17, the outer wall of the upper disc body 12 is provided with a second air hole 14, the outer wall of the second air hole 14 is provided with an air outlet 16, and the inside of the second air hole 14 is fixedly connected with a guide plate 15.

[0036] By setting the first air hole 13 and the second air hole 14, the wind enters the interior of the T-shaped slot 17. The position where the wind passes can drive the heat inside the brake disc body 1 through the wind. The wind enters the interior of the T-shaped slot 17, which further enhances the heat dissipation of the brake disc body 1 and avoids the wind flowing only on the outer wall of the brake disc body 1. Accordingly, the wind enters the interior of the T-shaped slot 17, which further improves the heat dissipation effect of the brake disc body 1.

[0037] Embodiment 2. On the basis of embodiment 1, the outer wall on one side of the fixed rod 2 is fixedly connected with a hinge 22, and the hinge 22 is internally rotatably connected with a force-bearing rod 23. A guide groove is provided on the outer wall at the top of the force-bearing rod 23, and a limiting groove is provided inside the movable rod 21. The inside of the limiting groove is slidably connected to the outer wall of the force-bearing rod 23. A pressure plate 24 is slidably connected to the upper part of the movable rod 21. The outer wall at the bottom of the pressure plate 24 is fixedly connected with a limiting rod 25. The outer wall at the bottom of the pressure plate 24 is located on both sides of the limiting rod 25 and is fixedly connected with a return spring 26. The outer wall at the bottom of the limiting rod 25 is movably plugged into the inside of the force-bearing rod 23. The outer wall at the bottom of the upper disk 12 is located above the pressure plate 24 and is provided with a groove 27. The outer wall of the pressure plate 24 is movably plugged into the inside of the groove 27.

[0038] When the bottom of the limiting rod 25 enters the track groove, the pressure plate 24 enters the groove 27. At this time, the fixation between the limiting rod 25 and the force rod 23 is released, and the buffer mechanism starts to work. Through the cooperation of the limiting rod 25 and the force rod 23, when the brake disc body 1 is slowly braked, the impact force on the brake disc body 1 will be weakened. At this time, the limiting rod 25 and the force rod 23 will not separate, thereby ensuring the stability and reliability of the brake system.

[0039] Embodiment three, on the basis of embodiment two, the buffer mechanism includes hinge two 4, the outer wall on one side of the plurality of hinge two 4 is fixedly connected to the outer wall on one side of the fixed rod 2, the interior of the hinge two 4 is rotatably connected to the shell 41, the interior of the shell 41 is slidably connected to the moving rod 42, the outer wall at one end of the moving rod 42 is rotatably connected to hinge three 43, the outer wall on one side of the hinge three 43 is fixedly connected to the outer wall on one side of the movable rod 21, the outer wall on one side of the moving rod 42 is fixedly connected to a buffer spring 45, the outer wall at one end of the buffer spring 45 is fixedly connected to the interior of the shell 41, the outer wall on one side of the fixed rod 2 is fixedly connected to an elastic sheet 3, the interior of the shell 41 is provided with a damping fluid 44, the outer walls on the upper and lower sides of the moving rod 42 are provided with placement grooves, and the interior of the placement grooves is fixedly connected with a telescopic groove 46.

[0040] The extrusion force generated by the housing 41 on the buffer spring 45 during movement can cause the buffer spring 45 to deform to absorb and store energy, thereby buffering the impact force on the T-slot 17, thereby preventing the T-slot 17 from being abraded due to sudden braking, thereby increasing the impact force on the occupants of the vehicle. Accordingly, the impact force generated during sudden braking is reduced by buffering the T-slot 17, thereby improving the stability of the brake system and the riding comfort. By setting the damping fluid 44, the resistance of the moving rod 42 entering the shell 41 can be increased, and the speed and force of the moving rod 42 entering the shell 41 can be slowed down. At the same time, additional damping force is provided for the buffer spring 45, further slowing down the rotation and rebound speed of the buffer spring 45. Accordingly, the buffer spring 45 can return to its initial state more smoothly after being subjected to impact force, thereby extending the service life of the buffer spring 45.

[0041] Embodiment 4, on the basis of embodiment 3, the outer wall at one end of the shell 41 is fixedly connected to a fixed plate 51, the interior of the fixed plate 51 is rotatably connected to a rotating shaft 52, the outer walls on the upper and lower sides of the rotating shaft 52 are fixedly connected to fan blades 5, the middle position of the outer wall of the rotating shaft 52 is fixedly connected to a gear 53, the outer wall at the top of the moving rod 42 is provided with a through groove 55, the inner wall of the through groove 55 is fixedly connected to a gear seat 54, and the outer wall on one side of the gear seat 54 is meshed with the outer wall of the gear 53.

[0042] By rotating the fan blades 5, the wind force inside the T-slot 17 can be increased, further increasing the heat dissipation effect on the upper disk body 12. When the outlet through the air outlet 16 is in an inclined state, the increased wind force is blown off the dust on the surface of the upper disk body 12 when discharged through the air outlet 16, thereby increasing the cleanliness of the surface of the upper disk body 12, ensuring effective contact between the brake pads and the upper disk body 12, and thus improving the sensitivity and response speed of the brake.

[0043] Embodiment 5, on the basis of embodiment 3, a sliding groove 71 is provided on the outer wall of the top of the moving rod 42 near the through groove 55, and a push rod 7 is slidably connected inside the sliding groove 71, and the outer wall at one end of the push rod 7 is fixedly connected to the outer wall of one side of the fixed plate 51, and an oil filling pipe 72 is provided inside the moving rod 42 at one end of the sliding groove 71, and a push rod 74 is slidably connected inside the one end of the oil filling pipe 72, and a sealing plate 73 is fixedly connected to the outer wall of one end of the push rod 74, and the outer wall of the sealing plate 73 is slidably connected to the inside of the oil filling pipe 72, and a force plate 75 is fixedly connected to the outer wall of the other end of the push rod 74, and the outer wall of one side of the force plate 75 An elastic block 76 is fixedly connected, the outer wall of one end of the elastic block 76 is fixedly connected to the outer wall of one side of the oil filling pipe 72, the outer wall of the other side of the force plate 75 is in movably contact with the outer wall of one side of the push rod 7, and a temporary storage groove 8 is provided inside the movable rod 42 below the oil filling pipe 72, a push plate 81 is movably connected to the lower part of the temporary storage groove 8, an air bag 82 is fixedly connected to the outer wall at the bottom of the push plate 81, a feeding port 83 is provided on the outer wall at the top of the temporary storage groove 8, an addition pipe 84 is fixedly connected to the bottom of the push plate 81, an air intake pipe 85 is fixedly connected to the bottom of the air bag 82, and the inner part of the air intake pipe 85 is sleeved with the outer wall of the addition pipe 84.

[0044] Through the cylindrical hole opened inside the moving rod 42, the lubricating oil can enter the contact surface between the hinge three 43 and the moving rod 42 through the cylindrical hole, thereby reducing the friction between the moving rod 42 and the hinge three 43. By reducing the friction between the moving rod 42 and the hinge three 43, more energy can be effectively transferred to the buffer mechanism to achieve the expected buffering effect. At the same time, the noise generated by the movement between the moving rod 42 and the hinge three 43 is reduced.

[0045] Embodiment 6. On the basis of embodiment 3, the outer wall on one side of the moving rod 42 is located on one side of the telescopic slot 46 and is fixedly connected with a circulation hole 6, the inside of the circulation hole 6 is slidably connected with a resistance plate 61, the outer walls on both sides of the resistance plate 61 are fixedly connected with protrusions, the outer walls on both sides of the protrusions are fixedly connected with resistance springs 62, and strip grooves are opened on both sides of the inside of the circulation hole 6, and the inside of the strip groove is fixedly connected to the outer wall of one end of the resistance spring 62.

[0046] By removing the blockage of the resistance plate 61 on the circulation hole 6, the damping fluid 44 can enter the interior of the telescopic groove 46 through the circulation hole 6. When the impact force is small, the moving rod 42 cannot enter the interior of the shell 41 to work. Through the coordinated design of the resistance plate 61 and the circulation hole 6, the damping fluid 44 can generate sufficient driving force to move the resistance plate 61 only under a sufficiently large impact force, ensuring that the braking system will not over-respond during normal driving or slight braking, thereby improving the stability and reliability of the system.

[0047] The working principle and use process of the present invention are as follows: when working, firstly, the brake disc body 1 formed by aluminum alloy is installed to the position of use, so that the brake disc body 1 can work. The density of the brake disc body 1 formed by aluminum alloy is much lower than that of iron and steel. The brake disc body 1 made of aluminum alloy can significantly reduce the overall weight of the vehicle. At the same time, the aluminum alloy brake disc body 1 is not easy to rust and corrode, thereby increasing the service life of the brake disc body 1.

[0048] When the brake disc body 1 rotates, the wind force generated in the surroundings enters the air duct 11. Through the setting of the air duct 11, the heat generated by the brake disc body 1 during operation can be quickly taken away by the wind, thereby increasing the heat dissipation effect of the brake disc body 1. The wind entering the air duct 11 will enter the inside of the T-shaped slot 17 through the first air hole 13, and finally be discharged through the second air hole 14. Through the setting of the first air hole 13 and the second air hole 14, the wind enters the inside of the T-shaped slot 17. The position where the wind passes can drive the heat inside the brake disc body 1 through the wind. The wind enters the inside of the T-shaped slot 17, further enhancing the heat dissipation effect on the brake disc body 1, avoiding the wind only flowing on the outer wall of the brake disc body 1, and correspondingly entering the inside of the T-shaped slot 17 through the wind, further improving the heat dissipation effect on the brake disc body 1.

[0049] When the brake disc body 1 is braked suddenly, the rotating brake disc body 1 will suddenly brake. At this time, under the impact force generated by the sudden stop of the brake disc body 1, the upper disc body 12 drives the movable rod 21 to move inside the T-slot 17, and then uses the force of inertia. When the movable rod 21 approaches the fixed rod 2, the limit rod 25 can be moved out from the inside of the force-bearing rod 23, so that the bottom of the limit rod 25 enters the inside of the track groove and the pressure plate 24 enters the inside of the groove 27. At this time, the fixation between the limit rod 25 and the force-bearing rod 23 is released, and the buffer mechanism can start working. Through the cooperation of the limit rod 25 and the force-bearing rod 23, when the brake disc body 1 is slowly braked, the impact force on the brake disc body 1 will be weakened. At this time, the limit rod 25 and the force-bearing rod 23 will not separate, thereby ensuring the stability and reliability of the braking system.

[0050] By releasing the fixation between the limit rod 25 and the force-bearing rod 23, the elastic sheet 3 and the buffer mechanism can work at the same time. At this time, the movable rod 21 can be subjected to force and transmitted to the elastic sheet 3 and the hinge three 43 at the same time. When the hinge three 43 is subjected to force, the movable rod 42 can be driven to move toward the inside of the shell 41. The extrusion force generated on the buffer spring 45 when the shell 41 moves can cause the buffer spring 45 to deform, absorb and store energy, thereby buffering the impact force received by the T-slot 17, avoiding sudden braking of the T-slot 17, which will increase the wear of the T-slot 17 and increase the impact force on the occupants of the vehicle. Accordingly, by buffering the T-slot 17, the impact force generated during sudden braking is reduced, while the stability of the braking system and the riding comfort are improved.

[0051] When the moving rod 42 moves toward the inside of the shell 41, the damping fluid 44 inside the shell 41 can be pressurized, so that the damping fluid 44 enters into the telescopic groove 46 through the circulation hole 6, and the damping fluid 44 inside the shell 41 can be reduced, so that the moving rod 42 can enter into the shell 41. By setting the damping fluid 44, the resistance of the moving rod 42 entering into the shell 41 can be increased, and the speed and force of the moving rod 42 entering into the shell 41 can be slowed down. At the same time, additional damping force is provided for the buffer spring 45, further slowing down the rotation and rebound speed of the buffer spring 45, and accordingly, the buffer spring 45 can more smoothly return to its initial state after being subjected to impact force, thereby extending the service life of the buffer spring 45.

[0052] When the moving rod 42 moves toward the inside of the shell 41, the pressure inside the shell 41 can be increased. The force of the pressure can increase the driving force of the damping fluid 44, so that the damping fluid 44 pushes the resistance plate 61 inside the circulation hole 6 to one end of the circulation hole 6, and the blockage of the circulation hole 6 by the resistance plate 61 can be released, so that the damping fluid 44 enters the expansion groove 46 through the circulation hole 6. When the impact force is small, the moving rod 42 cannot enter the inside of the shell 41 to work. Through the coordinated design of the resistance plate 61 and the circulation hole 6, only under a sufficiently large impact force can the damping fluid 44 generate enough driving force to move the resistance plate 61, ensuring that the braking system will not over-respond during normal driving or slight braking, thereby improving the stability and reliability of the system.

[0053] It should be noted that when the moving rod 42 is restored to its original position, the inner wall of the shell 41 can intercept the expansion groove 46 when the moving rod 42 moves from the inside of the shell 41 to the outside, so that the expansion groove 46 is squeezed under the action of the outward movement of the moving rod 42, so that the damping fluid 44 inside the expansion groove 46 re-enters the inside of the shell 41.

[0054] It should be noted that: under the action of the elastic sheet 3 and the buffer spring 45 , the movable rod 21 is pushed to return to its original position.

[0055] By moving the moving rod 42 back and forth at the bottom of the shell 41, the moving rod 42 can drive the tooth seat 54 to move accordingly, and then through the movement of the tooth seat 54, the gear 53 can drive the rotating shaft 52 to rotate on the fixed plate 51. Through the fixed connection between the fan blade 5 and the rotating shaft 52, the fan blade 5 can move accordingly when the rotating shaft 52 rotates. Then, through the rotation of the fan blade 5, the wind force inside the T-slot 17 can be increased, and the heat dissipation effect on the upper disk body 12 is further enhanced. When the outlet through the air outlet 16 is in an inclined state, the increased wind force is blown off the dust on the surface of the upper disk body 12 when it is discharged through the air outlet 16, thereby increasing the cleanliness of the surface of the upper disk body 12, ensuring effective contact between the brake pad and the upper disk body 12, and thus improving the sensitivity and response speed of the brake.

[0056] The push rod 7 provided on the fixed plate 51 can drive the sliding groove 71 to slide on the push rod 7 when the moving rod 42 moves toward the interior of the shell 41. When the force-bearing plate 75 contacts the push rod 7, the push rod 7 can generate an intercepting force on the force-bearing plate 75 when the moving rod 42 continues to move toward the interior of the shell 41. At this time, the intercepting force can be used to make the force-bearing plate 75 stop the push rod 74 from following the moving rod 42 and continuing to move. At this time, under the action of the sealing plate 73, the internal lubricating oil of the oil filling pipe 72 can be pushed, and the lubricating oil can enter the contact surface between the hinge three 43 and the moving rod 42 through the cylindrical hole opened in the moving rod 42, thereby reducing the friction between the moving rod 42 and the hinge three 43. By reducing the friction between the moving rod 42 and the hinge three 43, more energy can be effectively transferred to the buffer mechanism to achieve the expected buffering effect. At the same time, the noise generated by the movement between the moving rod 42 and the hinge three 43 is reduced.

[0057] By connecting the air source to the air inlet pipe 85, the airbag 82 can be inflated. When the air-inspired gas inside the airbag 82 expands, it will push the push plate 81 to move upward inside the temporary storage tank 8, so that the lubricating oil inside the temporary storage tank 8 is added to the inside of the oil filling pipe 72 through the feeding port 83. When the air source is separated from the air inlet pipe 85, the gas inside the airbag 82 will be discharged. By connecting the oil filling pipe 72 to the adding pipe 84, lubricating oil can be added to the inside of the temporary storage tank 8. By setting the temporary storage tank 8, lubricating oil can be stored for the oil filling pipe 72. By setting the adding pipe 84 inside the air inlet pipe 85, when the airbag 82 expands, the adding pipe 84 can slide inside the air inlet pipe 85 but will not leave the inside of the air inlet pipe 85, so that the adding pipe 84 can return to its original position when the airbag 82 becomes deflated.

[0058] It should be noted that one-way valves are provided inside the cylindrical hole, the feed port 83 and the addition pipe 84. The one-way valve, also known as a check valve, a non-return valve or a non-return valve, is a valve that can automatically prevent the backflow of fluid.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
