According to the high-heat-dissipation type brake disc, when a driver treads a brake in a long downhill, the telescopic oil cylinder can drive the second brake pad to make contact with the disc body at the moment, so that primary braking can be conducted, when the friction coefficient is reduced due to heat generated on the surface of the disc body, the brake continues to be treaded at the moment, and the telescopic oil cylinder cannot drive the second brake pad to be pushed outwards to the right side any more; when braking is finished and the brake is loosened, the whole movable clamp is pushed to move towards the left side by a counter-acting force, so that the first brake pad can be driven to be in contact with the disc body for braking, and the piston rod synchronously moves towards the left side, so that water in an external automobile glass water tank can be pumped into the piston barrel; and at the moment, the telescopic oil cylinder resets to drive the piston rod to reset, so that water in the piston barrel can enter the water spraying pipe and is sprayed out to cool the disc body, the disc body can be efficiently cooled, and effective braking is carried out.

Description

Technical Field

[0001] This utility model relates to the field of brake disc technology, specifically a high heat dissipation brake disc. Background Technology

[0002] The traditional disc brake principle is as follows: When braking is required, brake fluid is pressurized by the pump, causing a single telescopic cylinder to actuate and bring the brake pads into contact with the brake disc. Since there is only a single telescopic cylinder, only one brake pad is in contact with the disc, providing initial braking. As brake fluid continues to be added, the telescopic cylinder can no longer push outward, resulting in a reaction force that moves the entire caliper, bringing the other brake pad into contact with the brake disc. When both brake pads are in contact with the brake disc, 100% braking effect can be achieved.

[0003] The aforementioned disc brake structure has the following drawbacks during use: When a vehicle is descending a long slope, frequent braking is required, causing the brake disc to generate high heat. When the brake disc temperature is too high, its coefficient of friction decreases. This means that during braking, the friction between the brake pads and the brake disc decreases, resulting in a longer braking distance, reduced braking effectiveness, and ineffective braking, potentially even causing brake disc deformation. Therefore, to address these drawbacks, we propose a high-heat-dissipation brake disc. Utility Model Content

[0004] The purpose of this invention is to provide a high heat dissipation brake disc to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high heat dissipation brake disc, comprising:

[0006] The brake disc body consists of a disc body and a mounting disc disposed on the right side of the disc body;

[0007] A brake caliper, the brake caliper including a bracket and a movable caliper disposed on the surface of the bracket;

[0008] The bracket consists of a connecting plate, a support frame, and two guide rods fixedly installed on the left side of the connecting plate, with the upper end of the support frame fixedly connected to the surfaces of the two guide rods respectively.

[0009] The movable clamp includes a clamp body slidably mounted on the surface of a guide rod, a telescopic cylinder fixedly mounted on the left side of the clamp body, a first brake pad fixedly mounted on the right side wall of the clamp body, a second brake pad disposed inside the clamp body, and a reset assembly disposed on the surface of the guide rod for driving the clamp body to reset. The telescopic end of the telescopic cylinder extends into the interior of the clamp body and is fixedly connected to the left side of the second brake pad.

[0010] The heat dissipation structure includes a piston cylinder fixedly installed on the right side of the connecting plate, a piston rod disposed on the inner wall of the piston cylinder, a water spray pipe fixedly installed on the upper surface of the clamp body, and a water supply assembly disposed on the surface of the piston cylinder, and a through groove is provided on the upper surface of the clamp body.

[0011] Preferably, the reset assembly includes a reset spring sleeved on the surface of the guide rod and a baffle fixedly installed on the left end of the guide rod.

[0012] Preferably, one end of the reset spring is fixedly connected to the left side of the clamp body, and the other end of the reset spring is fixedly connected to the right side of the baffle.

[0013] Preferably, the water supply assembly includes an inlet pipe and an outlet pipe fixedly installed on the surface of the piston cylinder, and a connecting pipe fixedly installed at the inlet end of the spray pipe, wherein the end of the outlet pipe away from the piston cylinder is connected to the interior of the connecting pipe.

[0014] Preferably, both the inlet pipe and the connecting pipe are equipped with one-way valves, and the end of the inlet pipe away from the piston cylinder is connected to the external automotive windshield washer fluid tank.

[0015] Preferably, the left end of the piston rod is fixedly connected to the right side of the clamp body.

[0016] Preferably, the surface of the mounting plate is threaded with mounting bolts, and the surface of the plate is provided with threaded holes that are compatible with the mounting bolts.

[0017] This high-heat-dissipation brake disc, through the design of brake calipers and a heat dissipation structure, allows for initial braking when the driver applies the brakes on a long downhill slope. The hydraulic cylinder drives the second brake pad to contact the disc, initiating initial braking. As heat accumulates on the disc surface, reducing the coefficient of friction, continued braking prevents the hydraulic cylinder from pushing the second brake pad to the right. This creates a reaction force that moves the entire caliper to the left, ensuring both the first and second brake pads contact the disc for efficient braking. Simultaneously, the piston rod moves to the left, drawing water from the external windshield washer fluid reservoir into the piston cylinder. When the brakes are released, the hydraulic cylinder resets, causing the piston rod to return to its original position. This allows water from the piston cylinder to enter the washer nozzle and be sprayed out to cool the disc, achieving efficient cooling and effective braking.

[0018] This high-heat-dissipation brake disc features a return spring. When the movable caliper moves to the left, it slides along the surface of the guide rod, causing the return spring to stretch. When the telescopic cylinder resets, the return spring pushes the movable caliper back to its original position, thus causing the first brake pad to disengage from the disc body, facilitating the reset of the first brake pad.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-3 This utility model provides a technical solution: a high heat dissipation brake disc, including: a brake disc body, a brake caliper and a heat dissipation structure.

[0025] The brake disc body consists of a disc body 10 and a mounting disc 11 located on the right side of the disc body 10. The surface of the mounting disc 11 is threaded with mounting bolts 70, and the surface of the disc body 10 is provided with threaded holes that are compatible with the mounting bolts 70. The mounting disc 11 is placed on the disc body 10, and then the mounting bolts 70 are screwed into the threaded holes, thereby fixing the mounting disc 11 to the disc body 10. When the disc body 10 is worn or damaged, the mounting bolts 70 can be unscrewed to replace the disc body 10, while retaining the mounting disc 11, thus saving replacement costs.

[0026] The brake caliper includes a bracket and a movable caliper mounted on the surface of the bracket.

[0027] The bracket consists of a connecting plate 20, a support frame 21, and two guide rods 22 that are fixedly installed on the left side of the connecting plate 20. The upper end of the support frame 21 is fixedly connected to the surface of the two guide rods 22, thereby connecting the support frame 21 to the external vehicle body and allowing the bracket to be installed on the external vehicle body.

[0028] The movable clamp includes a clamp body 30 slidably mounted on the surface of the guide rod 22, a telescopic cylinder 31 fixedly mounted on the left side of the clamp body 30, a first brake pad 32 fixedly mounted on the right side wall inside the clamp body 30, a second brake pad 33 disposed inside the clamp body 30, and a reset assembly disposed on the surface of the guide rod 22 for driving the clamp body 30 to reset. The telescopic end of the telescopic cylinder 31 extends into the interior of the clamp body 30 and is fixedly connected to the left side of the second brake pad 33.

[0029] Both the brake disc body and the brake caliper are mounted on the external vehicle body. At this time, the disc body 10 is inside the movable caliper. When the driver presses the brake on a long downhill slope, the telescopic cylinder 31 will drive the second brake pad 33 to contact the disc body 10, thereby performing initial braking. When the surface of the disc body 10 generates heat and the coefficient of friction decreases, if the driver continues to press the brake, the telescopic cylinder 31 can no longer drive the second brake pad 33 to push outward to the right. Therefore, there will be a reaction force that pushes the entire movable caliper to the left, thereby driving the first brake pad 32 and the first brake pad 33 to contact the disc body 10 for efficient braking.

[0030] The reset assembly includes a reset spring 50 sleeved on the surface of the guide rod 22 and a baffle 51 fixedly installed on the left end of the guide rod 22. One end of the reset spring 50 is fixedly connected to the left side of the clamp body 30, and the other end of the reset spring 50 is fixedly connected to the right side of the baffle 51. When the movable clamp moves to the left, the movable clamp will slide along the surface of the guide rod 22, thereby driving the reset spring 50 to stretch. When the telescopic cylinder 31 resets, the reset spring 50 can push the movable clamp to reset, thereby driving the first brake pad 32 to disengage from the disc body 10, which facilitates the reset of the first brake pad 32.

[0031] The heat dissipation structure includes a piston cylinder 40 fixedly installed on the right side of the connecting plate 20, a piston rod 41 disposed on the inner wall of the piston cylinder 40, a water spray pipe 42 fixedly installed on the upper surface of the clamp body 30, and a water supply assembly disposed on the surface of the piston cylinder 40. The left end of the piston rod 41 is fixedly connected to the right side of the clamp body 30, and a through groove 43 is provided on the upper surface of the clamp body 30.

[0032] The water supply assembly includes an inlet pipe 60 and a drain pipe 61, which are respectively fixedly installed on the surface of the piston cylinder 40, and a connecting pipe 62, which is fixedly installed on the inlet end of the spray pipe 42. The end of the drain pipe 61 away from the piston cylinder 40 is connected to the interior of the connecting pipe 62. Both the inlet pipe 60 and the connecting pipe 62 are provided with one-way valves 63. The end of the inlet pipe 60 away from the piston cylinder 40 is connected to the external automotive windshield washer fluid tank. The one-way valve 63 on the surface of the inlet pipe 60 can prevent water in the piston cylinder 40 from flowing out along the inlet pipe 60. The one-way valve 63 on the surface of the connecting pipe 62 can prevent water in the spray pipe 42 from entering the piston cylinder 40.

[0033] When the caliper 30 moves to the left, the piston rod 41 moves synchronously to the left because the bracket is fixed to the external vehicle and does not move. This allows water from the external car windshield washer fluid tank to be drawn into the piston cylinder 40 along the inlet pipe 60. When the brake is released after braking, the resetting of the telescopic cylinder 31 will drive the piston rod 41 to reset. This allows water from the piston cylinder 40 to enter the water spray pipe 42 along the drain pipe 61 and connecting pipe 62, and spray water to cool the disc 10. This provides efficient cooling of the disc 10 and effective braking.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
