Description

Technical Field

[0001] This invention relates to the field of brake technology, specifically to a disc brake. Background Technology

[0002] A brake, also known as a brake, is a mechanical part that stops or slows down moving parts in a machine. A brake mainly consists of a frame, braking components, and operating devices. Some brakes are also equipped with automatic adjustment devices for the clearance of the braking components. In order to reduce braking torque, brakes are usually installed on the high-speed shaft of the equipment, but for large equipment with high safety requirements, they should be installed on the low-speed shaft near the working part of the equipment. Some brakes have been standardized and serialized and are manufactured by specialized factories for selection. Brakes are widely used, so the deceleration effect of brakes is crucial.

[0003] When braking, the brakes generate a lot of heat. If the heat is not dissipated in time, the brake discs and brake pads will become too hot, which can easily lead to brake failure. The main way to dissipate heat is through air cooling during driving. However, the existing brakes are not convenient to adjust the airflow, and the cooling is only done in the front and rear directions, which is a single cooling method. Summary of the Invention

A piston is slidably inserted inside the second oil supply chamber. A first spring is fixedly connected between one end of the piston and the second oil supply chamber.

[0013] (III) Beneficial Effects

[0014] This invention provides a disc brake, which has the following advantages:

[0015] 1. In this invention, the adjustment component is configured to adjust the position of the two baffles and adjust the area of ​​the opening. When the gap between the two baffles becomes smaller, the airflow blowing towards the brake pad decreases; when the gap between the two baffles becomes larger, the airflow blowing towards the brake pad increases. This achieves flexible adjustment, keeping the brake pad at a suitable and stable position and avoiding high temperature. This method provides front and rear heat dissipation.

[0016] 2. In this invention, by activating the cylinder, the upper heat dissipation holes on the surface of the insert correspond to the lower heat dissipation holes. External air enters the insert through the air inlet and then dissipates heat from above the brake pad through the upper and lower heat dissipation holes. Furthermore, this heat dissipation method, in conjunction with the front and rear heat dissipation methods, makes the heat dissipation effect better and keeps the brake pad at a safe temperature.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Please see Figures 1 to 6 The present invention provides a technical solution: a disc brake, including a brake caliper body 1, an opening 103 at the bottom of the brake caliper body 1, a first oil supply chamber 102 inside the brake caliper body 1, and second oil supply chambers 101 at both ends of the first oil supply chamber 102. A piston 2 is slidably inserted inside the second oil supply chamber 101. A first spring 4 is fixedly connected between one end of the piston 2 and the second oil supply chamber 101. The other end of the piston 2 extends into the opening 103 and is fixedly installed with a brake pad 3. An oil inlet pipe 5 communicating with the first oil supply chamber 102 is fixedly connected to the top of the brake caliper body 1. Two symmetrically distributed baffles 17 are provided on the front side of the opening 103. An adjustment assembly is fixedly installed on the top of the brake caliper body 1.

[0026] During the oil supply process, hydraulic oil is input from the oil inlet pipe 5 into the first oil delivery chamber 102, and then the hydraulic oil enters the second oil delivery chamber 101, pushing the piston 2 to move, so that the brake pad 3 contacts the brake disc to realize the braking operation.

[0027] The adjustable component allows for adjustment of the position of the two baffles 17 and the area of ​​the opening 103. When the gap between the two baffles 17 decreases, the airflow blowing onto the brake pad 3 decreases; when the gap between the two baffles 17 increases, the airflow blowing onto the brake pad 3 increases. This flexible adjustment keeps the brake pad 3 at a suitable and stable level, avoiding high temperatures. This method provides front and rear heat dissipation.

[0028] Specifically, the adjustment assembly includes a fixed frame 12 fixed to the top of the brake caliper body 1. A motor 13 is fixedly installed at one end of the fixed frame 12. A bidirectional lead screw 15 is fixedly connected to the output end of the motor 13. Two symmetrically distributed nut blocks 14 are threaded on the bidirectional lead screw 15. The front end of the nut blocks 14 is fixedly connected to the baffle 17. A guide rod 16 that moves through the nut blocks 14 is fixedly connected between the inner walls of the fixed frame 12.

[0029] The start motor 13 drives the double-acting lead screw 15 to rotate. The double-acting lead screw 15 drives the two nut blocks 14 to move closer to each other. The nut blocks 14 drive the corresponding baffles 17 to move, so that the two baffles 17 move closer to each other and the distance between the baffles 17 decreases. The reverse start motor 13 drives the double-acting lead screw 15 to rotate in the opposite direction, so that the distance between the two baffles 17 increases. During the driving process, the wind generated is usually blown from the front of the car to the rear of the car, blowing onto the brake pads 3 to cool them down and prevent the brake pads 3 from overheating.

[0030] To further improve the cooling effect on the brake pad 3, a sleeve 20 is fixedly connected to the top wall inside the opening 103. An air inlet 201 is opened at the end of the sleeve 20, and multiple lower heat dissipation holes 23 are opened at the bottom of the sleeve 20. A strip 21 is provided inside the sleeve 20, and multiple upper heat dissipation holes 22 are opened on the surface of the strip 21. A connecting strip 19 is fixedly connected to the end of the strip 21. A cylinder 18 is fixedly installed on the top of the brake caliper body 1, and the output end of the cylinder 18 is fixedly connected to the connecting strip 19.

[0031] By activating cylinder 18, the upper heat dissipation hole 22 on the surface of insert 21 aligns with the lower heat dissipation hole 23. External air enters insert 20 through air inlet 201, and then blows from above brake pad 3 through upper heat dissipation hole 22 and lower heat dissipation hole 23 to dissipate heat from brake pad 3. Furthermore, this heat dissipation method, in conjunction with front and rear heat dissipation, makes the heat dissipation effect better, keeping brake pad 3 at a safe temperature.

[0032] The brake caliper body 1 has heat dissipation columns 6 embedded on both side walls. One end of the heat dissipation column 6 is located inside the first oil supply chamber 102. A power sliding sleeve 7 is fitted on the heat dissipation column 6. A brush 11 for cleaning the heat dissipation column 6 is fixedly connected to the inner wall of the power sliding sleeve 7. An elastic component is fixedly connected to the surface of the brake caliper body 1.

[0033] In actual hydraulic transmission, the temperature of the hydraulic oil inside the first oil delivery chamber 102 and the second oil delivery chamber 101 rises, requiring cooling. In this solution, a heat dissipation column 6 is installed to transport the high temperature generated by the hydraulic oil to the outside. Since the heat will be conducted, the temperature of the piston 2 and the brake pad 3 will be further cooled. Furthermore, during the driving process, due to inertia, the power sleeve 7 will be moved by the elastic component. The brush 11 inside the power sleeve 7 cleans the heat dissipation column 6 to prevent the accumulated dust from affecting heat dissipation.

[0034] The aforementioned elastic component includes two limiting rods 8 fixed to the side wall of the brake caliper body 1, a power sliding sleeve 7 slidably sleeved on the limiting rods 8, a connecting block 10 fixedly connected to one end of the limiting rod 8, and a second spring 9 sleeved on the limiting rod 8. The two ends of the second spring 9 are fixedly connected to the connecting block 10 and the power sliding sleeve 7, respectively.

[0035] When the car turns or changes lanes, the power sleeve 7 slides on the limit rod 8, and under the elastic force of the second spring 9, the power sleeve 7 is pushed back to its original position. In this way, the brush 11 inside the power sleeve 7 cleans the heat dissipation column 6 and prevents the accumulated dust from affecting heat dissipation.

[0036] In order to detect the temperature of the brake pad 3 inside the opening 103, a temperature sensor 24 is fixedly connected to the inner wall of the opening 103. In this way, the temperature sensor 24 can detect the temperature at the brake pad 3 and adjust the position of the baffle 17 according to the temperature.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
