[0002] The brake disc is an important component of a car when braking. The quality of the car's braking performance directly affects the car's driving safety. The brake disc is actually a disc-shaped object with a round shape. When the car is driving, the brake disc rotates with the car's drive shaft. When the car brakes, the brake caliper clamps the side of the brake disc through the brake pad to generate friction resistance, forming braking force, and slowing down or stopping the car.

[0003] In the process of the brake caliper clamping the brake disc, a large amount of heat is generated between the two due to the intense friction, which will affect the service life of the brake disc.

[0029] Embodiment 1

[0030] Reference Figure 1-Figure 2The present invention discloses a water-cooled brake disc structure, comprising a disc body 1, a caliper 2 and brake pads 3 located on both sides of the disc body 1, and also comprising: an exhaust member 4 arranged inside the caliper 2, one side of the exhaust member 4 is connected to a liquid inlet pipe 5, and the other side of the exhaust member 4 is connected to a liquid discharge pipe 6. When the brake pads 3 on both sides are moving away from or approaching each other, the exhaust member 4 sprays the cooling liquid through the liquid inlet pipe 5 and the liquid discharge pipe 6 to the side of the disc body 1; when the brake pads 3 on both sides are controlled to move away from or approach each other, that is, when the brakes are pulled or released, the exhaust member 4 can be driven to exhaust the external cooling liquid, so that the external cooling liquid is drawn from the liquid inlet pipe 5 to the liquid discharge pipe 6 and then sprayed to the side of the disc body 1, so as to cool the disc body 1 by liquid; a plurality of heat dissipation holes 12 are evenly distributed on the surface of the brake disc, and the heat dissipation efficiency of the brake disc can be effectively improved through the cooperation of air cooling and water cooling, so as to prevent the disc body from overheating and ensure the effectiveness of braking.

[0031] In detail, in this embodiment, it also includes an oil cylinder 7, a first oil pipe 8 and a second oil pipe 9 installed on the side wall of the caliper 2. The oil cylinder 7 is a bidirectional oil cylinder. One end of the first oil pipe 8 is fixedly connected and communicated with the outer end of the oil cylinder 7, and one end of the second oil pipe 9 is fixedly connected and communicated with the inner end of the oil cylinder 7. The other interfaces of the first oil pipe 8 and the second oil pipe 9 are both connected and communicated with the external oil delivery device. The telescopic ends of the oil cylinder 7 located on the two side walls of the caliper 2 are fixedly connected to the sides of the brake pads 3 on both sides in a one-to-one correspondence. When braking, oil is injected into the first oil pipe 8 through the external oil delivery device, and the output end of the oil cylinder 7 extends, driving the brake pads 3 on both sides to approach the disc body 1. The brake pads 3 on both sides contact the disc body 1 at the same time, and friction braking is performed. Then the oil delivery device injects oil into the second oil pipe 9, and the extended end of the oil cylinder 7 shrinks, so that the brake pads 3 are separated from the disc body 1, and the brake is released.

[0032] Reference Figure 3In detail, in the present embodiment, the exhaust member 4 comprises a piston cylinder 401 fixed to the top of the inner cavity of the caliper 2, the piston 402 is sealingly and slidably connected to the inner sides of the piston cylinder 401, a piston rod 407 is fixed to one side wall of the piston 402, and the end of the piston rod 407 away from the piston cylinder 401 is fixedly connected to the brake pad 3 through a vertical plate 403, one side of the piston cylinder 401 is connected to the liquid inlet pipe 5 through a first one-way valve 404 and a three-way pipe 406, and the other side of the piston cylinder 401 is connected to the drain pipe 6 through a second one-way valve 405, a spray member 11 is fixed to the inner wall of the caliper 2, and the drain pipe 6 is connected to the spray member 11 located on the inner side of the caliper 2. As can be seen from the above, when braking, the brake pads 3 on both sides are driven to approach the disc body 1 under the action of external oil pressure. At least one side of the brake pad 3 is connected to the vertical plate 403. Since the stroke of the brake pad 3 is short, in this embodiment, the brake pads 3 on both sides will drive the piston rods 407 on both sides to move through the vertical plate 403. The piston rod 407 drives the piston 402 to pump the coolant into the piston cylinders 401 on both sides through the liquid inlet pipe 5 during the reciprocating motion of the piston cylinder 401, and then the coolant is discharged from the discharge pipes 6 on both sides and sprayed to the brake pads 3 to cool the brake pads 3. The whole process does not require the consumption of electricity resources, which is beneficial to energy saving and environmental protection, and reduces the cost of use.

[0033] Embodiment 2

[0034] Reference Figure 2 and Figure 4 In order to clean the surface of the brake disc and reduce the impact of debris and dust on the brakes in this embodiment, based on the same concept as the above-mentioned embodiment 1, this water-cooled brake disc structure also includes a cleaning piece 10. The cleaning piece 10 includes a cleaning plate 1001 arranged on the vertical plate 403. The cleaning plate 1001 has a cleaning layer 1002 evenly distributed on the surface of the side facing the brake pad 3. The cleaning layer 1002 is composed of a plurality of strip-shaped protrusions made of wear-resistant metal material. When the braking operation is not performed, the cleaning layer 1002 does not clean the brake pad 3, so as to avoid the cleaning layer 1002 and the brake pad 3 being in contact with each other and causing mutual wear. In the present invention, when the brake pads 3 are close to each other during braking, the cleaning layer 1002 can gradually contact the brake pad 3, thereby cleaning the brake pad 3 to ensure the service life of the cleaning layer 1002 and the brake pad 3.

[0035] Among them, a movable column 1003 is fixed on the back of the cleaning plate 1001, and one end of the movable column 1003 away from the cleaning plate 1001 passes through the vertical plate 403, and a spring 1004 is connected between the cleaning plate 1001 and the vertical plate 403. Under the action of the spring 1004, before the brake pad 3 is located in contact with the disc body 1, the distance between the cleaning layer 1002 and the disc body 1 is smaller than the distance between the brake pad 3 and the disc body 1, and does not contact the disc body 1. When the brake pad 3 gradually approaches the disc body 1, the cleaning layer 1002 will first contact the disc body 1, and clean the surface of the disc body 1 before the brake pad 3 contacts the disc body 1. After the brake pad 3 contacts the disc body 1, the cleaning layer 1002 will keep in contact with the disc body 1 under the action of the spring 1004, so as to achieve the cleanliness of the contact surface between the brake pad 3 and the disc body 1 and reduce the influence of debris and dust on the brake.

[0036] Embodiment 3

[0037] Reference Figure 4-Figure 5 Based on the same concept as the above-mentioned embodiment 2, the water-cooled brake disc structure also includes a spray part 11 including a main pipe 1101 fixed on the inner wall of the caliper 2, one end of the main pipe 1101 is connected to the drain pipe 6, and the side wall of the main pipe 1101 is evenly distributed with multiple first liquid outlets 1102, the interior of the movable column 1003 is hollow, and the interior of the cleaning plate 1001 is provided with a second liquid outlet 1103 that penetrates the two side walls of the cleaning plate 1001, the second liquid outlet 1103 is fixedly connected and communicated with one end of the movable column 1003, and the other end of the movable column 1003 is fixedly connected and communicated with the first liquid outlet 1102 through a bellows 1104. The present invention guides the first liquid outlet 1102 on the main pipe 1101 to the second liquid outlet 1103 through the movable column 1003 for discharge. On the one hand, it can avoid the possibility that the peripherals of the second liquid outlet 1103 are easily damaged. On the other hand, the coolant discharged from the second liquid outlet 1103 directly flows to the cleaning surface between the cleaning layer 1002 and the disk body 1, thereby improving the cleaning effect.

[0038] The cleaning layer 1002 has a gap 1105 in communication with the second liquid outlet 1103. The cleaning layer 1002 can clean impurities from the surface of the disk body 1. The cleaning layer 1002 protects the second liquid outlet 1103 to a certain extent. When the cleaning layer 1002 is worn to the second liquid outlet 1103, the cleaning layer 1002 should be replaced in time. A filter 1106 is embedded in the second liquid outlet 1103. The filter 1106 can prevent external impurities from entering the second liquid outlet 1103 to cause blockage to a certain extent.

[0039] Working principle: During the braking process, the brake pads 3 can be controlled to move closer or farther away, that is, to pull the brake or release the brake, through the external oil delivery device, the oil cylinder 7, the first oil guide pipe 8 and the second oil guide pipe 9; for example, when braking, when the brake pads 3 on both sides are close to each other, the vertical plate 403 will synchronously drive the piston rods 407 on both sides to move, and the piston rod 407 drives the piston 402 to draw the coolant into the piston cylinder 401 through the liquid inlet pipe 5 during the reciprocating motion of the piston cylinder 401, and then the coolant is discharged through the rear liquid discharge pipe 6 and sprayed to the brake pads 3 to cool the brake pads 3. The whole process does not require the consumption of electricity resources, which is beneficial to energy saving and environmental protection, and reduces the cost of use.

[0040] At the same time, before the brake pad 3 is located in contact with the disc body 1, the distance between the cleaning layer 1002 and the disc body 1 is smaller than the distance between the brake pad 3 and the disc body 1, and the cleaning layer 1002 does not contact the disc body 1, that is, the cleaning layer 1002 does not clean the brake pad 3 when the braking work is not performed, so as to avoid the cleaning layer 1002 and the brake pad 3 being in contact with each other and causing mutual wear; when the brake pad 3 gradually approaches the disc body 1, the cleaning layer 1002 will preferentially contact with the disc body 1, and clean the surface of the disc body 1 before the brake pad 3 contacts with the disc body 1; after the brake pad 3 contacts with the disc body 1, the cleaning layer 1002 will keep in contact with the disc body 1 under the action of the spring 1004, so as to achieve the cleanliness of the contact surface between the brake pad 3 and the disc body 1 and reduce the influence of debris and dust on braking.

[0041] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
