Description

Technical Field

[0001] The utility model relates to the field of brake discs, in particular to a carbon-ceramic brake disc with rapid cooling. Background Art

[0002] Carbon ceramic brake disc is a high-performance brake system component made of carbon fiber reinforced silicon carbide composite material. It is widely used in high-end automobiles, racing cars and high-speed transportation vehicles due to its lightweight, excellent high temperature resistance, long life and stable friction performance, providing better braking effect and durability.

[0003] At present, the existing brake disc usually achieves heat dissipation effect by allowing the wind to enter the inside of the brake disc driven by the guide plate when the brake disc rotates when the car is running. After searching, the Chinese patent announcement number: CN220910301U discloses a ventilated brake disc, which includes a first brake disc, a second brake disc, a connecting block, a fixing ring, a mounting tube and a connecting plate. The first brake disc has the same structure as the second brake disc. The first brake disc is provided with a ventilation hole assembly, a ventilation groove and an air guide arc groove. The air guide arc groove is arranged on a side of the first brake disc close to the connecting block. An air inlet gap is arranged between the mounting tube and the connecting plate. The fixing ring is also provided with an air inlet. The end of the mounting tube close to the connecting plate is also provided with a through hole. The above application document can effectively increase the amount of cold air entering between the first brake pad and the second brake pad through the air inlet gap, improve the efficiency of cold and heat exchange, and thus improve the heat dissipation efficiency of the entire brake disc. The air guide arc groove can guide the hot air on the one hand and improve the air circulation speed. On the other hand, it increases the contact area between the cold air and the brake disc to improve the speed of heat exchange.

In special circumstances, the staff may need to reverse at a faster speed to facilitate the vehicle to travel in different directions. Therefore, a carbon-ceramic brake disc with rapid cooling is proposed to solve the above problems. Utility Model Content

Through the setting of the connecting block 2, the front brake pad 1 and the rear brake pad 1 can be fixed into one.

[0033] Reference Figure 3 - Figure 5 The air guide assembly 3 is provided on the inner side of the brake pad 1, and the air guide assembly 3 includes an air guide block 31. The air guide block 31 is in the shape of a rectangular parallelepiped, and the end of the air guide block 31 away from the connecting block 2 is set to an arc surface. The shape setting of the air guide block 31 ensures that when the air guide block 31 moves to the outside of the brake pad 1, the wind body can be introduced into the position between the two brake pads 1. The outer wall of the air guide block 31 is slidably connected to the outer wall of the connecting block 2, and the inner wall of the brake pad 1 and the rear end of the air guide block 31 are jointly provided with a movable groove 32, and the inner wall of the movable groove 32 is slidably connected with a slide 33, and the outer wall of the slide 33 is fixedly connected to the rear end of the air guide block 31, and the end of the slide 33 away from the outer side of the brake pad 1 is elastically connected to the inner wall of the movable groove 32 by a spring 34, one end of the spring 34 is fixedly connected to the end of the slide 33 away from the outer side of the brake pad 1, and the other end of the spring 34 is fixedly connected to the inner wall of the movable groove 32.

[0034] Reference Figure 1 - Figure 3A starting assembly 4 is provided at the front end of the brake pad 1, and the starting assembly 4 includes a mounting ring 41, the cross-sectional shape of the mounting ring 41 is L-shaped, and the overall shape of the mounting ring 41 is annular, the rear end of the mounting ring 41 is fixedly connected to the front end of the front brake pad 1, and a mounting groove 42 is provided on the inner wall of the mounting ring 41, and the shape of the mounting groove 42 is arc-shaped, and a mounting block 43 is slidably connected to the inner wall of the mounting groove 42, and the shape of the mounting block 43 is a shape formed by connecting a rectangular parallelepiped at the front end and a cylinder at the rear end, and a through hole for connecting to other structures of the automobile is provided in the middle of the mounting block 43, and the shape setting of the mounting block 43 ensures that the mounting block 43 moves to the leftmost or rightmost end of the mounting groove 42 before driving the mounting ring 41 to rotate, and a control ring 44 is fixedly connected to the rear end of the mounting block 43, the cross-sectional shape of the control ring 44 is L-shaped, and the overall shape of the control ring 44 is annular, and the outer wall of the control ring 44 is rotatably connected to the inner wall of the mounting ring 41.

[0035] Reference Figure 2 - Figure 4 The outer wall of the control ring 44 is fixedly connected with a control plate 45, and the length of the control plate 45 in the front-to-back direction is consistent with the length of the connecting block 2. The inner wall of the connecting block 2 is provided with a mounting chamber 46, and the inner wall of the mounting chamber 46 is slidably connected with a clamping rod 47. The shape of the clamping rod 47 is a shape formed by two rectangular blocks cut with triangular prisms and a long rod connected. The shape setting of the clamping rod 47 ensures that the clamping rod 47 can generate horizontal movement after being subjected to vertical force, and one of the rectangular blocks with cut corners can drive the other after being subjected to force. The rectangular body moves, and the end of the clamping rod 47 away from the air guide block 31 is elastically connected to the inner wall of the mounting chamber 46 through the spring 2 48, one end of the spring 2 48 is fixedly connected to the end of the clamping rod 47 away from the air guide block 31, and the other end of the spring 2 48 is fixedly connected to the inner wall of the mounting chamber 46. A clamping groove 49 is provided at one end of the air guide block 31 close to the connecting block 2, and a baffle 410 is fixedly connected to the front end of the mounting ring 41. When the mounting block 43 moves to the two ends of the mounting groove 42, the rectangular part of the mounting block 43 just contacts the baffle 410.

[0036] Working principle: When in use, when the mounting block 43 rotates to the two ends of the mounting groove 42, the mounting block 43 drives the control ring 44 to rotate, so that the control ring 44 drives the control plate 45 to rotate, so that the control plate 45 moves to fit the card rod 47 matching the air guide block 31 matching the rotation direction, so that the card rod 47 moves to enter the interior of the mounting bin 46, so that the card rod 47 leaves the interior of the card groove 49 of the air guide block 31 matching the direction of rotation.

[0037] At the same time, under the elastic force of spring 2 48, the outer rectangular part of the clamping rod 47 corresponding to the air guide block 31 that does not match the rotation direction is located inside the clamping groove 49, so at this time only the air guide block 31 that matches the rotation direction is in a movable state.

[0038] At the same time, during the rotation process, the mounting block 43 drives the mounting ring 41 to rotate through the mounting groove 42, and drives the brake pad 1 to rotate through the mounting ring 41. During the rotation of the brake pad 1, the air guide block 31 moves in the direction away from the brake pad 1 under the action of centrifugal force, so that the air guide block 31 moves to the outside of the brake pad 1. Therefore, during the rotation of the brake pad 1, the wind body can move in the direction of entering the middle part of the brake pad 1 under the action of the arc surface of the air guide block 31, thereby taking away the heat in the middle part of the brake pad 1, achieving the effect of heat dissipation and cooling.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
