Description

Technical Field

[0001] This invention relates to the field of brake disc technology, and in particular to a heat-resistant, crack-resistant, creep-ink brake disc. Background Technology

[0002] Vermicular graphite cast iron was successfully developed in the mid-1960s. Its graphite morphology is between flake graphite and spheroidal graphite, therefore its mechanical properties are also between those of ordinary gray cast iron and ductile cast iron. The chemical composition (%) of vermicular graphite cast iron is typically: C 3.5–3.9, Si 2.2–2.8, Mn 0.4–0.8, P < 0.06, S < 0.06, R (rare earth) 0.04–0.06. Its physical and casting properties are superior to ductile cast iron and close to those of ordinary gray cast iron. Vermicular graphite cast iron is widely used to manufacture steel ingot molds, exhaust pipes, cylinders, etc. Brake discs are the friction pairs of disc brakes; in addition to the strength and rigidity required as components, they should also have the highest possible and most stable coefficient of friction, as well as appropriate wear resistance, heat resistance, heat dissipation, and heat capacity.

[0003] Existing vermicular ink brake discs achieve rapid heat dissipation during braking by incorporating air ducts, holes, and grooves, allowing airflow for cooling. However, since the brake disc rotates synchronously with the wheels, airflow in the brake disc ducts slows down when the vehicle is moving at low speeds or stopped. After the vehicle comes to a complete stop, the heat inside the brake disc can only be dissipated by itself. Compared to when the vehicle is moving, the heat dissipation effect of the brake disc decreases rapidly. High temperatures can lead to thermal fade, resulting in reduced braking force. Vehicles are also more prone to encountering muddy roads, causing dirt to adhere to the surface of the brake disc. The grooves on the surface of existing brake discs are also prone to leaving dirt residue, affecting airflow and reducing the effectiveness of dust removal during braking friction. Summary of the Invention

[0004] The main objective of this invention is to provide a thermal crack-resistant vermicular ink brake disc, which can effectively solve the problems in the background art.

Several sets of actuating mechanisms are provided inside the two sets of side skirt rings near the edge to promote the heat dissipation mechanism to complete autonomous rotation.

[0007] Preferably, the inner ring and the two sets of side skirt rings are an integral structure, the outer sides of the two sets of side skirt rings are respectively fitted onto the bearing, and the several sets of connecting holes are respectively arranged between two adjacent sets of fan blades.

[0008] Preferably, the fan blades are arc-shaped, the coolant does not fill the interior of the hollow tube shell, and the two sets of gaskets are respectively located on the outer side of the two sets of side skirt rings.

[0009] Preferably, the actuating mechanism includes several sets of circular grooves fixedly disposed inside the two sets of side skirt rings near the edge, a movable plate movably disposed inside the circular groove, a hollow cylinder fixedly disposed at one end of the movable plate, a counterweight fixedly disposed at one end of the hollow cylinder, an opening being disposed on one side of the side skirt ring near the counterweight, and a first spring fixedly disposed at one end of the movable plate and the inner wall of one side of the circular groove.

[0010] Preferably, the movable piece is adapted to the circular groove, and the counterweight passes through the inside of the opening.

[0011] Preferably, the rinsing mechanism includes several sets of air guide grooves inside the two sets of brake pads. A lower air groove is provided inside the brake pad near the lower side of the air guide groove. Five sets of side air grooves are provided inside the brake pad near the air guide groove. A fixed shell is fixedly provided at one end of the brake pad corresponding to the lower air groove. A movable block is movably provided inside the fixed shell. A fixed shaft is fixedly provided at one end of the movable block. A contact block is fixedly provided at one end of the fixed shaft. A second spring is fixedly provided between the movable block and one end of the brake pad. Four sets of air inlets are provided on the outer side of the fixed shell.

[0012] Preferably, the air guide groove is connected to the interior of the lower air groove and the side air groove, the lower air groove is connected to the interior of the fixed shell, and the movable block is fitted with the fixed shell.

[0013] Preferably, the fixed shaft extends through one side of the fixed shell, and one side of the contact block is arc-shaped, with the contact block corresponding to the rotation trajectory of the fixed rod.

[0014] Preferably, the inner side of both sets of brake pads is provided with several sets of circular holes, and the outer side of both sets of brake pads is provided with several sets of sliding grooves.

[0015] Preferably, the circular holes are arranged in a ring of five per group, and the grooves communicate with the interior of the downwind groove and the five groups of side wind grooves.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The two sets of brake pads have several sets of evenly arranged round holes. When the vehicle brakes, the two sets of brake pads generate heat with the inner side, which accelerates ventilation and heat dissipation, improves braking efficiency, suppresses braking noise, reduces weight, cleans, and exhausts air. The use of several sets of grooves further increases air circulation, improves heat dissipation performance, and can also quickly remove dust generated by friction, which greatly improves the brake pads' resistance to heat fading and makes driving safer.

[0018] 2. By using the mounting plate and several sets of mounting holes, the entire assembly is installed on the vehicle. As the vehicle moves, the two sets of brake pads, inner ring, and side skirt ring rotate. As the vehicle speed gradually increases, the centrifugal force generated by the rapid rotation will throw the counterweights in the circular grooves on both sides outward. At this time, the movable plate slides in the circular groove, stretching the first spring. Simultaneously, under the action of centrifugal force, several sets of counterweights thrown out will press against the pad rings on both sides. The friction generated after contact drives the entire heat dissipation mechanism to rotate. When the vehicle speed decreases or stops, several sets of counterweights will retract under the action of the first spring, allowing the heat dissipation mechanism to rotate autonomously and preventing large friction interference from affecting the overall rotation of the heat dissipation mechanism.

[0019] 3. As the two sets of gaskets are driven by the actuation mechanism, they rotate synchronously through the fixed fan blades, fixed ring plates, and the outer ring of the bearing. When the vehicle decelerates or stops using the two sets of brake pads, the actuation mechanism releases the friction restriction on the gaskets, causing the inner ring of the bearing, the fixed inner ring, and the brake pads to descend together. Meanwhile, the outer ring of the bearing drives the fixed ring plates and several sets of fan blades to continue rotating rapidly. Combined with the inertia generated by the rotating coolant in several sets of hollow tube shells, this further propels the rotation. The rotating fan blades drive the internal gas to cool down rapidly, thereby achieving self-cooling for a period of time after deceleration or stopping, further achieving the purpose of efficient heat dissipation and improving the resistance to thermal cracking.

[0020] 4. While the two side rings rotate at high speed, several sets of fixed rods on the surface will contact the contact block, pushing the fixed shaft and the movable block to move towards the inside of the fixed shell, compressing the second spring. The air entering through the air inlet is pushed to move towards the inside of the guide air groove, the lower air groove, and the five sets of side air grooves, achieving the purpose of reciprocating air filling. This causes the air to blow against the inside of several sets of grooves, blowing out the dirt that is easily stuck or stored inside, as well as the dust generated during friction, maintaining the cleanliness of the grooves and better facilitating air circulation between the grooves and the inside of the whole.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship as a relative relationship of orientation or position, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0034] Please see Figures 1-10An embodiment of the present invention provides a heat-resistant, crack-resistant, vermicular ink brake disc, comprising a mounting disc 1. A plurality of mounting holes 2 are provided on one side of the mounting disc 1. An inner ring 3 is fixedly disposed at one end of the mounting disc 1. Two sets of side skirt rings 4 are fixedly disposed on the outer side of the inner ring 3. Brake pads 5 are fixedly disposed on the outer side of the inner ring 3 near the outer sides of the two sets of side skirt rings 4. A plurality of connecting blocks 6 are fixedly disposed between the two sets of brake pads 5. Air ducts 7 are provided at adjacent positions between the plurality of connecting blocks 6. A heat dissipation mechanism 8 for high heat dissipation of the brake pads 5 as a whole is provided between the two sets of brake pads 5 on the outer side of the inner ring 3. The heat dissipation mechanism 8 includes a bearing 81 movably sleeved on the inner side of the two sets of side skirt rings 4 outside the inner ring 3. The outer ring of the bearing 81 is located near the middle position. A fixed ring plate 82 is fixedly installed. Several sets of connecting holes 83 are opened inside the fixed ring plate 82. Several sets of fan blades 84 are fixedly installed at both ends of the fixed ring plate 82. Hollow tube shells 85 are fixedly installed on the outer side of each set of fan blades 84. Coolant 86 is installed on the outer side of the hollow tube shells 85. Washer rings 87 are fixedly installed between the sets of fan blades 84 near the two sides of the fixed ring plate 82. Several fixing rods 88 are fixedly installed on the outer side of the washer rings 87. Several sets of actuating mechanisms 89 are provided inside the two sets of side skirt rings 4 near the edge to promote the heat dissipation mechanism 8 to complete the autonomous rotation. Several sets of rinsing mechanisms 810 are provided inside the two sets of brake pads 5 and at one end for cleaning the grooves on the surface of the brake pads 5.

[0035] The inner ring 3 and the two sets of side skirt rings 4 are an integral structure. The outer sides of the two sets of side skirt rings 4 are respectively fitted on the bearing 81. Several sets of connecting holes 83 are respectively set between the two adjacent sets of fan blades 84. The fan blades 84 are arc-shaped. The coolant 86 does not fill the interior of the hollow tube shell 85. The two sets of gaskets 87 are respectively set on the outer sides of the two sets of side skirt rings 4.

[0036] As the two sets of gaskets 87 are driven by the actuating mechanism 89, they rotate synchronously through the fixed fan blades 84, the fixed ring 82, and the outer ring of the bearing 81. When the vehicle decelerates or stops using the two sets of brake pads 5, the actuating mechanism 89 releases the friction restriction on the gaskets 87, causing the inner ring of the bearing 81 to descend together with the fixed inner ring 3 and the brake pads 5. Meanwhile, the outer ring of the bearing 81 drives the fixed ring 82 and several sets of fan blades 84 to continue rotating rapidly. Combined with the inertia generated by the coolant 86 in the several sets of hollow tube shells 85 during rotation, the rotation is further propelled. The rotating fan blades 84 drive the internal gas to cool down rapidly, thereby achieving self-cooling for a period of time after deceleration or stopping, further achieving the purpose of efficient heat dissipation and improving the resistance to thermal cracking.

[0037] The actuating mechanism 89 includes several sets of circular grooves 891 fixedly disposed inside the two sets of side skirt rings 4 near the edge. A movable piece 892 is movably disposed inside the circular grooves 891. A hollow cylinder 893 is fixedly disposed at one end of the movable piece 892. A counterweight 894 is fixedly disposed at one end of the hollow cylinder 893. An opening 895 is opened on one side of the side skirt ring 4 near the counterweight 894. A first spring 896 is fixedly disposed at one end of the movable piece 892 and the inner wall of one side of the circular groove 891. The movable piece 892 is adapted to the circular groove 891. The counterweight 894 passes through the inner side of the opening 895.

[0038] By using the mounting plate 1 in conjunction with several sets of mounting holes 2, the entire assembly is installed on the vehicle. As the vehicle moves, it drives the two sets of brake pads 5, inner ring 3, and side skirt ring 4 to rotate. As the vehicle speed gradually increases, the centrifugal force generated by the rapid rotation will throw the counterweights 894 in the circular grooves 891 on both sides outward. At this time, the movable plate 892 slides in the circular groove 891, stretching the first spring 896. Simultaneously, under the action of centrifugal force, the counterweights 894 thrown out will press against the pad rings 87 on both sides. The friction generated after contact drives the entire heat dissipation mechanism 8 to achieve the purpose of rotation. When the vehicle speed decreases or stops, the counterweights 894 will retract under the action of the first spring 896, so that the heat dissipation mechanism 8 can rotate autonomously, preventing the overall rotation of the heat dissipation mechanism 8 from being affected by large friction interference.

[0039] The flushing mechanism 810 includes several sets of air guide slots 8101 formed inside the two sets of brake pads 5. A lower air duct 8102 is formed inside the brake pad 5 near the lower side of the air guide slots 8101. Five sets of side air ducts 8103 are formed inside the brake pad 5 near the air guide slots 8101. A fixed housing 8104 is fixedly installed at one end of the brake pad 5 corresponding to the lower air duct 8102. A movable block 8105 is movably arranged inside the fixed housing 8104. A fixed shaft 8106 is fixedly installed at one end of the movable block 8105. A fixed shaft 8106 is fixedly installed at one end of the fixed shaft 8106. A second spring 8108 is fixedly installed between the contact block 8107, the movable block 8105 and one end of the brake pad 5. Four sets of air inlets 8109 are opened on the outer side of the fixed shell 8104. The air guide groove 8101 communicates with the interior of the lower air groove 8102 and the side air groove 8103. The lower air groove 8102 communicates with the interior of the fixed shell 8104. The movable block 8105 fits against the fixed shell 8104. The fixed shaft 8106 moves through one side of the fixed shell 8104. One side of the contact block 8107 is arc-shaped. The contact block 8107 corresponds to the rotation trajectory of the fixed rod 88.

[0040] While the two side pads 87 rotate at high speed, several fixed rods 88 fixed on the surface will contact the contact block 8107 respectively, pushing the fixed shaft 8106 and the movable block 8105 to move inward to the fixed shell 8104, compressing the second spring 8108. The air entering through the air inlet 8109 is pushed to move inward to the air guide groove 8101, the lower air groove 8102, and the five sets of side air grooves 8103, achieving the purpose of reciprocating air filling. This causes the air to blow into the inner side of several sets of grooves 10, blowing out the dirt that is easily stuck or stored inside and the dust generated during friction, maintaining the cleanliness of the grooves 10, and better facilitating the air circulation between the grooves 10 and the inner side of the whole.

[0041] The inner side of each of the two sets of brake pads 5 is provided with several sets of round holes 9, and the outer side of each of the two sets of brake pads 5 is provided with several sets of grooves 10. The round holes 9 are arranged in a ring of five in a group, and the grooves 10 are connected to the interior of the lower wind groove 8102 and the five sets of side wind grooves 8103.

[0042] The two sets of brake pads 5 have several sets of evenly arranged round holes 9. When the vehicle brakes, the two sets of brake pads 5 generate heat with the inner side, which accelerates ventilation and heat dissipation, improves braking efficiency, suppresses braking noise, reduces weight, cleans, and exhausts air. The use of several sets of grooves 10 further increases air circulation, improves heat dissipation performance, and can also quickly remove dust generated by friction, which greatly improves the heat fading resistance of the brake pads 5 and makes driving safer.

[0043] Working principle:

[0044] Firstly, the mounting disc 1, mounting holes 2, inner ring 3, and brake pads 5 are existing brake structure components. During use, several sets of evenly arranged circular holes 9 are formed on the two sets of brake pads 5. When the vehicle brakes, the two sets of brake pads 5 generate heat with their inner surfaces, accelerating ventilation and heat dissipation, improving braking efficiency, suppressing braking noise, reducing weight, cleaning, and exhausting air. The use of several sets of grooves 10 further increases airflow, improves heat dissipation performance, and quickly removes dust generated by friction, greatly improving the brake pads 5's resistance to heat fading and making driving safer. Secondly, through the use of the mounting disc 1 and several sets of mounting holes 2, the entire assembly is installed on the vehicle. As the vehicle moves, the two sets of brake pads 5, inner ring 3, and side skirt ring 4 rotate. As the vehicle speed gradually increases, the centrifugal force generated by rapid rotation will throw the counterweights 894 in the circular grooves 891 on both sides outward. At this time, the movable plate 892 slides in the circular grooves 891, stretching the first spring 896. Simultaneously, under the action of centrifugal force, several sets of counterweights 894 thrown out will press against the washers 87 on both sides. The friction generated after contact drives the overall heat dissipation mechanism 8 to rotate. When the vehicle speed decreases or stops, several sets of counterweights 894 will retract under the action of the first spring 896, allowing the heat dissipation mechanism 8 to rotate autonomously and preventing the overall rotation of the heat dissipation mechanism 8 from being affected by large friction interference. As the two sets of washers 87 are pressed against the washers 894, the heat dissipation mechanism 8 will rotate autonomously. Driven by the actuation mechanism 89, the fixed fan blades 84, fixed ring 82, and outer ring of bearing 81 rotate synchronously. When the vehicle decelerates or stops using the two sets of brake pads 5, the actuation mechanism 89 releases the friction restriction on the washer ring 87. This causes the inner ring of bearing 81 to descend along with the fixed inner ring 3 and brake pads 5. Meanwhile, the outer ring of bearing 81 drives the fixed ring 82 and several sets of fan blades 84 to continue rotating rapidly. Combined with the inertia generated by the rotating coolant 86 in several sets of hollow tube shells 85, this further propels the rotation. The rotating fan blades 84 drive the internal gas to cool down rapidly, thus achieving self-cooling for a period of time after deceleration or stopping, further completing efficient heat dissipation. The purpose of heating is to improve the resistance to heat cracking. In addition, while the two side pads 87 rotate at high speed, several fixed rods 88 fixed on the surface will contact the contact block 8107 respectively, pushing the fixed shaft 8106 and the movable block 8105 to move inward to the fixed shell 8104, compressing the second spring 8108. The air entering through the air inlet 8109 is pushed to move inward to the air guide groove 8101, the lower air groove 8102, and the five sets of side air grooves 8103, achieving the purpose of reciprocating air filling. This allows the air to blow out the inner side of several sets of grooves 10, blowing out the dirt that is easily stuck or stored inside and the dust generated during friction, maintaining the cleanliness of the grooves 10, and better facilitating the air circulation between the grooves 10 and the inner side of the whole.
