Description

Technical Field

[0001] This utility model relates to the field of automotive braking technology, specifically to automotive braking mechanisms. Background Technology

[0002] Currently, there are many devices that utilize friction to brake moving parts, which can be categorized by their mode of operation: circular surface braking, conical surface braking, and end-face braking. Although their modes of operation differ, their principles are the same: they all utilize the friction between a non-rotating non-metallic friction pad and a rotating metal part to achieve braking. For example, the rear braking system of the Santana car uses two brake shoes to rub against the inner cylindrical surface of the brake disc to achieve braking.

[0003] Chinese patent CN214929645U discloses an automotive braking device that solves the problems of reduced braking efficiency, increased braking distance, significant safety hazards, and limited overall usability of current automotive braking devices on the market. The device includes a brake disc and a brake caliper housing. The brake caliper housing is movably connected to the surface of the brake disc, and a brake caliper bracket is movably connected to the inner surface of the brake caliper housing. An installation port is provided on one side of the brake caliper bracket, and inner and outer friction pads are movably connected to both sides of the inner cavity of the brake caliper bracket. The surfaces of both the inner and outer friction pads are movably connected to the surface of the brake disc. This automotive braking device has a reasonable structural design, ensuring the flexibility and reliability of braking. It allows the brake disc and friction pads to maintain a consistent gap, preventing brake fade and effectively improving the safety of the vehicle during driving.

[0004] However, in the aforementioned patent, the inner and outer friction pads experience a delay in contact with the brake disc during braking, preventing them from applying braking force simultaneously. This leads to increased wear on the brake disc and a longer braking distance. Therefore, this invention proposes an automotive braking mechanism to address these problems. Utility Model Content

[0005] The purpose of this invention is to provide a braking mechanism for automobiles to solve the problem mentioned in the background art that the friction pads on both sides cannot simultaneously contact the brake disc.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automobile braking mechanism, comprising: a brake disc, a buffer tank, and a hydraulic pipe, wherein the buffer tank is connected to the hydraulic pipe, and a master cylinder is connected to both sides of the buffer tank via connecting pipes, and friction pad one and friction pad two are respectively connected to both ends of the master cylinder via a brake lever and a brake pin, wherein the brake disc contacts one side of friction pad one and friction pad two.

[0007] Preferably, the surface of the brake disc has several heat dissipation holes, the surface of the brake disc is fixedly connected with mounting pins, and both sides of the brake disc are in contact with friction pad one and friction pad two.

[0008] Preferably, the buffer tank is fixedly connected to the hydraulic pipe, and a connecting pipe is fixedly connected to both sides of the buffer tank. The other end of the connecting pipe is fixedly connected to the master cylinder of the brake. The master cylinder of the brake, the connecting pipe, the buffer tank and the hydraulic pipe are in communication. The buffer tank, the connecting pipe and the master cylinder of the brake contain hydraulic oil.

[0009] Preferably, one end of the brake master cylinder is fixedly connected to two connecting plates, and a brake rod is slidably connected at the midpoint of this end of the brake master cylinder, with the brake rod located between the two connecting plates. The other end of the brake master cylinder is slidably connected to a brake pin, and the other end of the brake pin is fixedly connected to a friction plate.

[0010] Preferably, the end of the brake lever away from the master cylinder is rotatably connected to a transmission rod, the two sides of the transmission rod are in contact with two connecting plates respectively, the transmission rod is rotatably connected to the two connecting plates, and the other end of the transmission rod is connected to the friction plate through a rotating groove.

[0011] Preferably, the friction plate has a rotating groove on the side away from the brake disc, and the inner wall of the rotating groove is rotatably connected to one end of the transmission rod. Two springs are fixedly connected to the surface of the friction plate, and the other ends of the two springs are fixedly connected to two connecting plates respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are: when the car needs to brake, high-pressure hydraulic oil is injected into the device through the hydraulic pipe. At this time, the hydraulic oil will simultaneously increase the pressure in the brake master cylinders on both sides through the buffer tank, so that the friction pads on both sides approach the brake disc at the same time, and then brake it at the same time, thereby reducing damage to the brake disc and reducing the braking distance.

[0018] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution: an automobile braking mechanism, including: a brake disc 1, a buffer tank 4, and a hydraulic pipe 5. The surface of the brake disc 1 is provided with several heat dissipation holes 2. During the braking process of the automobile, friction pad 11 and friction pad 2 14 will come into contact with the brake disc 1, generating a large amount of heat. The heat dissipation holes 2 can effectively eliminate this heat. The surface of the brake disc 1 is fixedly connected with a mounting pin 3, which facilitates the connection of the brake disc 1 to the wheel hub and other accessories, thereby installing the entire device in the corresponding position of the automobile. Both sides of the brake disc 1 are in contact with friction pad 11 and friction pad 2 14. The friction pad 11 and friction pad 2 14 come into contact with the brake disc 1 through friction, thereby achieving braking of the automobile.

[0020] The buffer tank 4 is fixedly connected to the hydraulic pipe 5. A connecting pipe 6 is fixedly connected to both sides of the buffer tank 4. When the vehicle brakes, high-pressure hydraulic oil is injected into the buffer tank 4 through the hydraulic pipe 5, thereby increasing the pressure inside the buffer tank 4. The other end of the connecting pipe 6 is fixedly connected to the brake master cylinder 7. The brake master cylinder 7, connecting pipe 6, buffer tank 4, and hydraulic pipe 5 are interconnected to facilitate synchronous pressurization. The buffer tank 4, connecting pipe 6, and brake master cylinder 7 contain hydraulic oil, allowing for the addition of hydraulic pressure without the need for an internal pin. Oil is used to increase the boosting speed. One end of the master cylinder 7 is fixedly connected to two connecting plates 10, and a brake lever 8 is slidably connected at the midpoint of this end of the master cylinder 7. When the pressure inside the master cylinder 7 increases, the brake lever 8 and the brake rod 15 will also move outward. The brake lever 8 is located between the two connecting plates 10. The other end of the master cylinder 7 is slidably connected to the brake rod 15, and the other end of the brake rod 15 is fixedly connected to a friction pad 14. When the brake rod 15 moves, the friction pad 14 will approach and contact the brake disc 1.

[0021] A transmission rod 9 is rotatably connected to the end of the brake lever 8 away from the master cylinder 7. The two sides of the transmission rod 9 are in contact with two connecting plates 10 respectively. The transmission rod 9 is rotatably connected to the two connecting plates 10. When the transmission rod 9 moves, since the position of the transmission rod 9 is fixed, its other end will start to rotate towards the brake disc 1 at a certain angle. The other end of the transmission rod 9 is connected to the friction pad 11 through the rotating groove 13. At this time, the friction pad 11 will gradually approach the brake disc 1 as the transmission rod 9 rotates. The side of the friction pad 11 away from the brake disc 1 has a rotating groove 13. The inner wall of the rotating groove 13 is rotatably connected to one end of the transmission rod 9. The rotating groove 13 facilitates the rotation of the transmission rod 9. Two springs 12 are fixedly connected to the surface of the friction pad 11. The other ends of the two springs 12 are fixedly connected to the two connecting plates 10 respectively. When the braking ends, the springs 12 will lift the friction pad 11 again so that it does not contact the brake disc 1.

[0022] When this device is working, if the car brake is applied, the car will pressurize the buffer tank 4 through hydraulic oil. Since the tank is full of hydraulic oil, the master cylinders 7 on both sides of the brake disc 1 will be under pressure at the same time, which will force the brake lever 8 and the brake column 15 to move. At this time, the friction pads 11 and 14 on both sides of the brake disc 1 will approach the brake disc 1 at the same time and make contact with it, thereby achieving braking. By braking both sides of the brake disc 1 at the same time, damage to the brake disc 1 itself can be reduced, and the braking distance can be shortened.

[0023] 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.
