[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0022] As Figures 1 to 5 shown, the disc type hydraulic brake provided by the embodiments of the present application comprises a brake bin 1, the top end of the brake bin 1 is fixedly connected with an oil pipe 2, the top end of the oil pipe 2 is provided with an upper pump assembly 3, the left and right sides of the center of the brake bin 1 are both fixedly connected with brake cylinders 4, the inner cavities of the brake cylinders 4 are movably sleeved with piston heads 5, one side of the piston head 5 close to the center of the brake bin 1 is fixedly connected with a brake plate 6, one side of the piston head 5 away from the brake plate 6 is fixedly connected with a connecting rod 7, one side of the connecting rod 7 away from the brake plate 6 is fixedly connected with a mounting plate 8, one side of the mounting plate 8 away from the brake plate 6 is fixedly connected with a cooling fin 9, the left and right sides of the brake bin 1 are both fixedly connected with cooling bins 11, one side of the cooling bin 11 away from the brake bin 1 is fixedly connected with a sealing sleeve II 12, the inner cavity of the sealing sleeve II 12 is sleeved with a cooling piece 13;

[0023] The working principle and beneficial effects of the above technical solution are that the hydraulic oil in the inner cavity of the brake bin 1 pushes the brake plate 6 to hold the brake disc, thereby achieving the effect of braking. When the piston head 5 moves, it drives the mounting plate 8 to move, thereby driving the cooling fin 9 to move towards the inner cavity of the brake bin 1, thereby transferring the heat of the hydraulic oil in the inner cavity of the brake bin 1 to the inner cavity of the cooling bin 11 through the cooling fin 9, thereby efficiently absorbing the heat through the cooling liquid in the inner cavity of the cooling bin 11, and transferring the heat of the cooling liquid to the air through the cooling fin 13, thereby achieving cooling of the hydraulic oil in the inner cavity of the brake bin 1, and through the double cooling method of water cooling and air cooling, the heat dissipation effect of the hydraulic oil in the inner cavity of the brake bin 1 is greatly improved.

[0024] As shown in Figure 5 In one embodiment, the rear side of the brake plate 6 is fixedly connected with a transmission rod 17, the side away from the brake plate 6 of the transmission rod 17 is fixedly connected with a limiting block 18, the rear side of the cooling bin 11 is fixedly connected with a sealing ring 19, the inner cavity of the sealing ring 19 movably sleeves a rotating rod 20, the rear end of the rotating rod 20 is fixedly connected with a wind fan 21, the front side of the rotating rod 20 is fixedly connected with a stirring fan 22, and the surface of the rotating rod 20 is fixedly connected with a limiting piece 23.

[0025] The working principle and beneficial effects of the above technical solution are that in order to improve the heat dissipation effect of the brake disc, the automobile is provided with a wind guiding component at the front of the vehicle to guide the wind generated during driving to the brake and blow on the surface of the brake disc. When the brake plate 6 brakes the brake disc, it drives the transmission rod 17 to move, which drives the limiting block 18 to move through the movement of the transmission rod 17, thereby separating the limiting block 18 from the limiting piece 23, thereby losing the limiting of the limiting piece 23, and then the wind fan 21 is driven by the wind, thereby driving the stirring fan 22 to rotate, which stirs the cooling liquid in the inner cavity of the cooling bin 11, thereby improving the flowability of the cooling liquid in the inner cavity of the cooling bin 11, and further improving the heat dissipation effect of the cooling liquid in the inner cavity of the cooling bin 11 on the cooling fin 9, thereby improving the heat dissipation performance of the hydraulic oil in the inner cavity of the brake bin 1.

[0026] As shown in Figure 2 In one embodiment, the left and right sides of the brake bin 1 are fixedly connected with sealing sleeves 10, the cooling fin 9 sleeves in the inner cavity of the sealing sleeve 10, and the side away from the brake bin 1 of the cooling fin 9 is located in the inner cavity of the cooling bin 11.

[0027] The working principle and beneficial effects of the above technical solution are that the cooling fin 9 sleeves in the inner cavity of the sealing sleeve 10, thereby blocking the hydraulic oil through the sealing sleeve 10, thereby sealing the inner cavity of the brake bin 1, and preventing the hydraulic oil in the inner cavity of the brake bin 1 from leaking out during the movement of the cooling fin 9.

[0028] AsFigure 3 As shown, in one embodiment, an inlet pipe 15 is fixedly connected to the upper side of the cooling chamber 11, and an outlet pipe 14 is fixedly connected to the lower side of the cooling chamber 11. Both the outlet pipe 14 and the inlet pipe 15 are threadedly connected to a plug head 16.

[0029] The working principle and beneficial effects of the above technical solution are as follows: When the coolant in the inner cavity of the cooling chamber 11 is used for a long time, the plug 16 in the inner cavity of the outlet pipe 14 is unscrewed to drain the coolant from the inner cavity of the cooling chamber 11. Then, the plug 16 in the inner cavity of the outlet pipe 14 is screwed back in. Next, the plug 16 in the inner cavity of the inlet pipe 15 is unscrewed to add coolant to the inner cavity of the cooling chamber 11, thereby replenishing the coolant in the inner cavity of the cooling chamber 11.

[0030] like Figure 2 As shown, in one embodiment, a ring is fixedly connected to the side of the inner cavity of the brake cylinder 4 away from the center of the brake chamber 1, and the ring is in contact with the piston head 5;

[0031] The working principle and beneficial effects of the above technical solution are as follows: A ring is fixedly connected to the side of the inner cavity of the brake cylinder 4 away from the center of the brake chamber 1, thereby blocking the piston head 5 through the ring. This prevents the heat sink 9 from being pushed when the hydraulic oil pushes the piston head 5, so that the pushing effect of the hydraulic oil will not affect the pushing effect of the piston head 5.

[0032] like Figure 3 As shown, in one embodiment, one side of the cooling plate 13 is located inside the cooling chamber 11 and the other side is located outside the cooling chamber 11, and the cooling plate 13 and the heat sink 9 are interleaved.

[0033] The working principle and beneficial effects of the above technical solution are as follows: one side of the cooling plate 13 is located inside the cooling chamber 11 and the other side is located outside the cooling chamber 11, so that the cooling plate 13 can transfer the heat absorbed by the coolant inside the cooling chamber 11 to the air, thereby improving the heat dissipation effect of the coolant inside the cooling chamber 11.

[0034] like Figure 4 As shown, in one embodiment, the stirring fan 22 is located inside the cooling chamber 11, and the fan 21 is located outside the cooling chamber 11.

[0035] The working principle and beneficial effects of the above technical solution are as follows: The stirring fan 22 is located in the inner cavity of the cooling chamber 11. When driven by the wind force of the fan 21, the stirring fan 22 can rotate to stir the coolant in the inner cavity of the cooling chamber 11, thereby improving the fluidity of the coolant in the inner cavity of the cooling chamber 11, thereby improving the contact efficiency between the coolant and the heat sink 9 and the cooling plate 13, thereby improving the heat dissipation of the cooling plate 13 and the heat sink 9.

[0036] like Figure 5As shown, in one embodiment, the limiting piece 23 is hexagonal, and the limiting block 18 is in contact with the limiting piece 23;

[0037] The working principle and beneficial effects of the above technical solution are that the limiting piece 23 is hexagonal, so that when the brake plate 6 is reset after braking, the limiting block 18 can contact the limiting piece 23, thereby limiting the limiting piece 23, preventing the wind fan 21 from rotating again, and thus achieving that the limiting piece 23 is driven by wind only during braking, thereby reducing the number of rotations of the limiting piece 23, reducing the failure rate of the rotating rod 20, the wind fan 21, and the stirring fan 22, and improving the service life of the rotating rod 20, the wind fan 21, and the stirring fan 22.

[0038] Working principle and use process: The upper pump assembly 3 pushes hydraulic oil, thereby changing the pressure of the hydraulic oil in the inner cavity of the brake chamber 1 through the oil pipe 2, thereby pushing the piston head 5 to move through the hydraulic oil in the inner cavity of the brake chamber 1, driving the brake plate 6 to move to the center of the brake chamber 1 through the movement of the piston head 5, thereby contacting the brake disc to brake;

[0039] When the brake plate 6 moves, the connecting rod 7 moves, thereby driving the mounting plate 8 to move, and driving the cooling fin 9 to move to the inner cavity of the brake chamber 1, thereby increasing the contact area of the cooling fin 9 and the hydraulic oil in the inner cavity of the brake chamber 1, and transferring the heat of the hydraulic oil to the inner cavity of the cooling chamber 11 through the cooling fin 9, and cooling the cooling fin 9 through the cooling liquid in the inner cavity of the cooling chamber 11, and then transferring the heat of the cooling liquid in the inner cavity of the cooling chamber 11 to the outside of the cooling chamber 11 through the cooling fin 13, thereby cooling the cooling liquid in the inner cavity of the cooling chamber 11;

[0040] When the brake plate 6 moves, the transmission rod 17 moves, thereby separating the limiting block 18 from the limiting piece 23, and then the wind is introduced to the brake disc of the wheel through the ventilation piece at the front of the vehicle during driving, thereby driving the wind fan 21 to rotate through the wind, and driving the stirring fan 22 to rotate through the rotation of the wind fan 21, thereby stirring the cooling liquid in the inner cavity of the cooling chamber 11 through the stirring fan 22.
