Description

Technical Field

[0001] This invention relates to the field of brake caliper technology, specifically to a hydraulic disc brake caliper. Background Technology

[0002] Hydraulic disc brake calipers are the core actuators in disc brake systems. Their main function is to convert hydraulic energy into mechanical braking force, thereby decelerating or stopping the vehicle by clamping the brake disc.

[0003] Currently, hydraulic disc brake calipers still have certain drawbacks in actual use. The existing brake discs are solid structures. After the brake pads are pressed against the brake disc, the solid brake disc will heat up rapidly. Under high temperature and wide contact, the wear of the brake pads will be accelerated, and the high temperature friction will further reduce the corrosion resistance of the brake disc.

[0004] In view of this, a hydraulic disc brake caliper was designed to solve the above problems. Summary of the Invention

[0009] In a preferred embodiment, the present invention can be further configured as follows: a U-shaped shell is provided in the pipe section near the connector of the shunt pipe, and a controller is installed in the U-shaped shell. A coil is connected to the controller, and a first magnet is provided in the coil. One end of the first magnet is magnetically attracted to a second magnet, and a plug is fixedly installed at the other end of the second magnet. A rubber ring is installed on the plug.

[0010] In a preferred embodiment, the present invention can be further configured such that: two L-shaped through holes are provided inside the inner frame; The plate cooling mechanism includes an inlet pipe and an outlet pipe installed in two L-shaped through holes, and an annular refrigeration pipe is installed on the inlet pipe and the outlet pipe. The outer surface of the annular refrigeration pipe is provided with multiple evenly distributed fan-shaped grooves.

[0011] In a preferred embodiment, the present invention can be further configured such that: the plate cooling mechanism further includes a mesh plate disposed on an inner frame, two second bolts are inserted into the mesh plate and fixedly installed in the inner frame, a limiting ring cover is fixedly installed on the mesh plate, a circular annular groove is opened in the limiting ring cover and a mesh pad is installed in the circular annular groove, a positioning ring is fixedly installed in the pipe section of the limiting ring cover, an impeller main shaft is movably installed in the positioning ring, and a gear is fixedly installed on the rod end of the impeller main shaft that extends through to the outside of the mesh plate.

[0012] In a preferred embodiment, the present invention can be further configured such that: the pressure-bearing mechanism includes a brake disc disposed outside the annular refrigeration pipe and the limiting ring cover, the brake disc having a plurality of evenly distributed studs, and ring supports mounted on the plurality of studs, the teeth at the outer end of the ring supports being adapted to mesh with gears.

[0013] In a preferred embodiment, the present invention can be further configured such that: the side of the brake disc has uniformly distributed rectangular slots, which facilitates the discharge channel for airflow after passing through multiple fan-shaped slots, thereby enhancing the natural cooling speed of the brake disc after forced braking.

[0014] In a preferred embodiment, the present invention may be further configured such that: a T-shaped tube section is provided inside the brake disc, and four horizontal holes are provided inside the T-shaped tube section, and a fixing member is inserted into the four horizontal holes, the fixing member being fixed to the wheel hub by means of a nut.

[0015] In a preferred embodiment, the present invention can be further configured such that: multiple annular grooves are formed on the outer surface of the brake disc to facilitate the natural cooling rate of the brake disc surface, further enhance the structural strength of the brake disc under pressure, and increase the area of ​​the brake pads pressed against the multiple annular grooves after being compressed, thereby further improving braking performance.

[0016] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows: 1. This invention optimizes the brake disc structure by using a semi-hollow brake disc with a disc surface cooling mechanism stacked in the hollow part of the disc. As the brake pads are pressed and pushed against the outer surface of the brake disc, the rotating impeller shaft, in conjunction with the annular cooling pipe, continuously blows high-pressure airflow towards the inner wall of the disc. Combined with the heat dissipation effect of multiple annular grooves on the outer surface of the disc, the temperature control effect of the brake disc can be improved during braking, effectively shortening the natural cooling rate of the brake disc, improving the safety of vehicle braking, and further avoiding the problem of accelerated corrosion of the brake disc under high temperature and high pressure conditions.

[0017] 2. This invention adds a brake pad pressurization mechanism to the braking mechanism and electrically connects the controller to the vehicle's infotainment system. When the brake pad wear intensifies, the vehicle's infotainment system controls the controller until the coil is energized. The magnetic field conversion between the two magnets pushes the plug head to slide outward. The negative pressure inside the main pipe and the shunt pipe pushes the plug rod and the insertion rod to move, which in turn pushes the pressurization block and squeezes the brake pad to extend outward. This effectively reduces replacement costs while increasing the service life of the brake caliper.

[0018] 3. By optimizing the structure of the brake disc and caliper body, this invention can improve vehicle braking safety while reducing cost losses. At the same time, the increased cross-sectional width of the brake disc can further enhance its resistance to pressure during forced braking of the vehicle, effectively improving the structural strength of the wide rear brake disc under sudden high temperature braking.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of a hydraulic disc brake caliper provided by the present invention. Example

[0024] Combination Figures 1 to 10As shown, the present invention provides a hydraulic disc brake caliper, including a braking mechanism 100, a brake pad pressurizing mechanism 200 installed within the braking mechanism 100, a pressure-bearing mechanism 300 disposed within the braking mechanism 100, and a disc cooling mechanism 400 installed between the braking mechanism 100 and the pressure-bearing mechanism 300. The braking mechanism 100 is used to enhance the structural stability of the brake pad pressurizing mechanism 200 and the disc cooling mechanism 400. The pressure-bearing mechanism 300, in conjunction with the disc cooling mechanism 400, can improve the braking surface and further enhance the strength of the braking structure. The brake pad pressurizing mechanism 200 is used to improve the service life of the brake and further reduce costs.

[0025] The braking mechanism 100 includes a housing 110, an inner frame 120 is installed inside the housing 110, and a symmetrically distributed pressure pad 150 and movable pad 140 are provided inside the inner frame 120. Two limiting posts 1401 are fixedly installed in the inner cavity of the movable pad 140, and a gasket 1403 and a brake pad 1404 are movably installed on the two limiting posts 1401. Two tension springs 1402 are fixedly connected between the gasket 1403 and the inner wall of the movable pad 140. The brake pad pressurization mechanism 200 includes multiple clamps 220 installed outside the inner frame 120, and a mother tube 210 is installed inside the multiple clamps 220. A stopper rod 230 is movably installed inside the inner frame 120. The other end of the stopper rod 230 is inserted into a plug rod 2301. Two lever arms 240 are movably installed at both ends of the plug rod 2301. A pressurization block 250 is movably installed on the two lever arms 240, penetrating into the inner frame 120 and the movable pad 140. The inner end slope of the pressurization block 250 is adapted to bear pressure on the slope of the middle part of the pad 1403. A rubber ring is installed on the head of the plug rod 230 that extends into the inner cavity of the mother tube 210. Two holes are opened in the plate sections on both sides of the clamp 220, and reinforcing bolts installed in the inner frame 120 are inserted into the holes. A shunt pipe 260 is installed at the outer end of the main pipe 210. A cover plate 130 is provided on the outside of the inner frame 120, and two first bolts 1301 are inserted into the cover plate 130. A flow guide shroud 280 is installed on the pipe section outside the cover plate 130, and a connector 270 is installed between the shunt pipe 260 and the flow guide shroud 280. A U-shaped shell is provided in the pipe section of the shunt pipe 260 near the connector 270, and a controller 290 is installed in the U-shaped shell. A coil 2901 is connected to the controller 290, and a first magnet 2902 is provided in the coil 2901. A second magnet 2903 is magnetically attracted to one end of the first magnet 2902, and a plug 2904 is fixedly installed on the other end of the second magnet 2903. A rubber ring is installed on the plug 2904.

[0026] Preferably, the outer shell 110 has a cylindrical hole in the plate segment near the cover plate 130, and the outer end of the movable pad 140 is provided with a protruding column head, and a rubber ring is provided on the protruding column head. When the protruding column head and the rubber ring are inserted into the cylindrical hole inside the outer shell 110, the cylindrical hole, which is sealed by the cover plate 130 and connected to the guide shroud 280, can realize the reciprocating extension of the movable pad 140 under hydraulic action, which is convenient for precise control of the actual extension length of the movable pad 140. Among them, the pressure pad 150 and the movable pad 140 have the same plate thickness, and the pressure pad 150 is a solid structure, which is used to provide limiting pressure protection for the surface of the limit ring cover 410 and the brake disc 310 after they are stacked. In addition, the limiting post 1401 is welded together with a guide rod and a washer, and the brake pad 1404 has two T-shaped holes inside, and the washer is inside the T-shaped hole. The washer 1403 and the brake pad 1404 are fixedly connected. When the two lever arms 240 are compressed and stretch relative to each other, the compressed booster block 250 will stretch laterally along the insertion hole inside the inner frame 120 and the movable pad 140, which makes it easier to control the lateral elongation rate of the brake pad 1404 and the washer 1403. The width of the insertion hole inside the movable pad 140 is twice the width of the insertion hole inside the inner frame 120. During actual use, when the surface wear of the brake pad 1404 intensifies, the controller 290 is energized through the vehicle's infotainment system. At this time, the energization of the coil 2901 changes the instantaneous magnetic field of the first magnet 2902, and the first magnet 2902 pushes the second magnet 2903 and the plug 2904 to extend. As the plug 2904 moves, the closed inner cavity of the main tube 210 and the shunt tube 260 will generate a negative pressure state, and the plug in the plug rod 230 will slide along the inner cavity of the main tube 210. The mechanical kinetic energy generated in this process can provide kinetic energy for the lateral extension of the booster block 250. Example

[0027] Combination Figure 4 , Figure 5 and Figure 9 As shown, based on Embodiment 1, the inner frame 120 has two L-shaped through holes inside; The plate cooling mechanism 400 includes a mesh plate 4101 set on the inner frame 120 and an inlet pipe 4301 and an outlet pipe 4302 installed in two L-shaped through holes. An annular cooling pipe 430 is installed on the inlet pipe 4301 and the outlet pipe 4302. The outer surface of the annular cooling pipe 430 is provided with a plurality of evenly distributed fan-shaped grooves 4303. Two second bolts 4102 are inserted into the mesh plate 4101, and the two second bolts 4102 are fixedly installed in the inner frame 120. A limiting ring cover 410 is fixedly installed on the mesh plate 4101. A circular groove is opened in the limiting ring cover 410, and a mesh pad 420 is installed in the circular groove. A positioning ring 460 is fixedly installed in the pipe section of the limiting ring cover 410. An impeller main shaft 440 is movably installed in the positioning ring 460, and a gear 450 is fixedly installed on the rod end of the impeller main shaft 440 that extends to the outside of the mesh plate 4101.

[0028] Preferably, the back of the annular cooling pipe 430 is coated with an adhesive to enhance the firmness of the fixation between the annular cooling pipe 430 and the limiting ring cover 410. When the gear 450 is driven by the transmission to drive the impeller main shaft 440 to rotate at high speed, the mesh plate 4101 with a mesh structure can introduce ambient air into the pipe section of the limiting ring cover 410. Finally, the airflow drawn in will converge and pass through the mesh pad 420 in a high-pressure manner. The filtered airflow will continue to blow along the inner wall of the brake disc 310 and the outer surface of the annular cooling pipe 430. Finally, the heat energy will dissipate outward from the fan-shaped groove 4303, thereby accelerating the natural cooling speed of the brake disc surface under sudden braking conditions, which is conducive to safer braking of vehicles that start and stop for short periods of time. Example

[0029] In the above embodiment, the pressure-bearing mechanism 300 includes a brake disc 310 disposed outside the annular cooling pipe 430 and the limiting ring cover 410. The brake disc 310 is provided with a plurality of studs 3101 evenly distributed inside. A ring support 330 is installed on the plurality of studs 3101. The teeth at the outer end of the ring support 330 are adapted to mesh with the gear 450. The brake disc 310 is provided with a T-shaped pipe section, and four horizontal holes are opened in the T-shaped pipe section. A fixing member 320 is inserted into the four horizontal holes. The fixing member 320 is fixed to the hub by means of a nut. The brake disc 310 has evenly distributed rectangular slots on its side, which facilitates the exhaust channel for the airflow after passing through multiple fan-shaped slots 4303, and enhances the natural cooling speed of the brake disc 310 after forced braking. The outer surface of the brake disc 310 has multiple annular grooves 3102, which facilitates the natural cooling rate of the brake disc 310 surface and further enhances the structural strength of the brake disc 310 under pressure. When the brake pad 1404 is under pressure, the area of ​​compression between it and the multiple annular grooves 3102 increases, further improving the braking performance.

[0030] Preferably, the middle part of the brake disc 310 facing the limiting ring cover 410 is a thickened structure, and the T-shaped tube section is located at the center of the thickened structure. The side of the annular cooling tube 430 away from the limiting ring cover 410 is adapted to fit against the inner wall of the annular cooling tube 430. At the same time, the inner wall of the brake disc 310, the annular cooling tube 430 and the surface of the limiting ring cover 410 are all smooth coated structures to reduce the frictional resistance of the brake disc 310 during rotation. The inner side of the ring support 330 is provided with multiple elliptical pads distributed in a circular pattern, and the elliptical pads have holes. Multiple studs 3101 are evenly distributed and are fitted into the holes of the multiple elliptical pads and fixed by nuts. The thickness of the ring support 330 is half that of the T-shaped tube section, which is used to enhance the safety of the ring support 330 during rotation. When the fixing member 320 is inserted into the T-shaped pipe section and the hub and fixed with the nut, the rotation of the hub will drive the fixing member 320, the brake disc 310 and the ring support 330 to rotate at the same speed. At this time, the teeth on the ring support 330 will mesh with the auxiliary gear 450, which will provide high-speed rotational kinetic energy for the impeller main shaft 440, making it easier to actively draw in airflow and improve the speed of natural cooling of the brake disc 310 during the coating braking process.

[0031] The working principle and usage process of this invention are as follows: The inlet pipe 4301 and the outlet pipe 4302 are installed in two L-shaped through holes reserved inside the inner frame 120. Then, the coolant is injected into the interior of the annular refrigeration pipe 430 through the inlet pipe 4301 using an external injector. The air inside the annular refrigeration pipe 430 is purged by the outlet pipe 4302 until the interior of the annular refrigeration pipe 430 is filled with coolant. Then, the inlet pipe 4301 and the port of the inlet pipe 4301 are fixed and sealed using two pipe caps. Next, the combined and stacked limiting ring cover 410 and annular cooling pipe 430 are assembled along the groove reserved on the front of the brake disc 310. Then, the ring support 330 is inserted into multiple studs 3101, and the inserted ring support 330 is fixed to the brake disc 310 with nuts. At this time, the teeth at the outer end of the ring support 330 are adapted to mesh with the gear 450. At this time, the outer surface of the assembled brake disc 310 and the limiting ring cover 410 are adapted to fit into the groove on the inner side of the inner frame 120. Then, the T-shaped tube section of the brake disc 310 is adapted to fit onto the vehicle wheel hub, and the fixing member 320 is inserted along the hole of the brake disc 310 and the vehicle wheel hub. The inserted fixing member 320 is fixed to the wheel hub with nuts. When in use, as the hub drives the pressure-bearing mechanism 300 to rotate, the disc cooling mechanism 400, which is in a wedge-shaped state, can cooperate with the rotation of the brake disc 310 and the ring support 330 to achieve a certain pressure protection. At the same time, the rotating ring support 330 will assist the gear 450 and the impeller main shaft 440 to rotate. Under the clamping action of the positioning ring 460 and the mesh plate 4101, the high-speed rotating impeller main shaft 440 will draw in air. The drawn-in air will be blown along the inner groove of the limiting ring cover 410 towards the annular cooling pipe 430 and the inner wall of the brake disc 310. Finally, the airflow will be discharged outward along multiple fan-shaped grooves 4303 and the grooves on the side of the brake disc 310. At this time, a high-pressure and high-velocity cooling airflow will be formed inside the brake disc 310, which can effectively reduce the cooling speed of the brake disc 310 after emergency braking and further improve the performance of the release braking. In order to reduce the cost of replacing the braking device after prolonged high-pressure braking of the vehicle, the controller 290 is energized through the vehicle system. The energized coil 2901 changes the magnetic field of the first magnet 2902. At this time, the second magnet 2903 and the plug 2904 are pressed and move laterally along the inner cavity of the connector 270. After the main tube 210 and the split tube 260 are sealed, the negative pressure generated in the inner cavity will pull the plug rod 230 to contract. At the same time, the plug rod 230 and the insertion rod 2301 will push the two lever arms 240 to extend synchronously. Finally, the pressure booster block 250 is pressed and moves laterally along the insertion hole inside the inner frame 120. Finally, the inclined surface of the inner end of the pressure booster block 250 will squeeze the pad 1403 until the pad 1403 and the brake pad 1404 are squeezed outward along the two limit posts 1401, further increasing the bearing pressure between the brake pad 1404 and the outer surface of the brake disc 310.

[0032] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
