An energy-efficient brake drum radiator for heavy-duty trucks

Abstract

This invention relates to the field of brake drum technology and discloses an energy-saving brake drum radiator for heavy-duty trucks, comprising an arc block, a driven gear, a driving gear, a main cooling water tank, and a cooling connecting groove. The arc block includes a top block and a bottom block, both of which have cooling grooves and inner grooves. This invention, through the coordinated arrangement of the arc block, driven gear, driving gear, main cooling water tank, roller, rotating drum, first gear, and bevel gear, achieves the following: after the driver applies the brakes, the roller follows the arc block and fits against the outer drum. This, through multiple structures, ultimately drives the driven gear and driving gear to rotate. Furthermore, since the second pipe is connected to the truck's water tank, the rotation of the driving gear increases the flow rate of water in the main cooling water tank, thereby improving cooling efficiency. The rotating drum also collects some of the braking kinetic energy, which is used to power the active cooling of the brake drum.

Description

Technical Field

[0001] This invention relates to the field of brake drum technology, specifically to an energy-saving brake drum radiator for heavy-duty trucks. Background Technology

[0002] A brake drum, technically known as a drum brake, generally consists of a rotating part, a fixed part, an actuating part, and a positioning and adjustment device. It comprises a brake backing plate, brake calipers, brake shoes, related linkages, springs, pins, and the brake drum itself. For heavy-duty trucks and other freight vehicles, heat dissipation of the brake drum is particularly important and is an essential element for safe driving.

[0003] Traditional brake drum cooling systems have the following main disadvantages: (1) Poor heat dissipation efficiency. Most traditional brake drum cooling devices use air cooling, which is inefficient and takes a long time to cool down.

[0004] (2) Consumes additional energy. Some brake drums use water cooling circulation to dissipate heat. These often require an external water pump to the water tank and additional power supply, which also results in more resource consumption.

[0017] (III) Beneficial Effects This invention provides an energy-saving brake drum radiator for heavy-duty trucks, which has the following advantages: (1) The present invention sets up a combination of structures such as an arc block, a driven gear, a driving gear, a heat dissipation main water tank, a roller, a rotating drum, a first gear and a bevel gear, so that after the driver steps on the brake, the roller will follow the arc block to fit against the outer drum, thereby driving the driven gear and the driving gear to rotate through multiple structures. Since the second pipe is connected to the truck water tank, the rotation of the driving gear can increase the flow rate of water in the heat dissipation main water tank, thereby improving the heat dissipation efficiency. Furthermore, the rotating drum is used to collect part of the braking kinetic energy and use this part of the kinetic energy to provide power for the active heat dissipation of the brake drum. (2) By setting up a rotating drum, transmission ring, coil spring, rotating sleeve, second push rod, fixing groove, groove and first gear, the present invention realizes that when the truck is in the forward state and brakes, the roller is attached to the outer drum and driven to rotate. The kinetic energy of its rotation is collected by the inner coil spring. Even after the truck stops, the coil spring can still provide power to the drive gear to pump cold water out of the water tank. Furthermore, the second push rod and groove can prevent the coil spring from over-accumulating force and breaking. (3) By setting up the cooperation of structures such as roller, movable rod, toothed disc, inner tooth, first torsion spring, and second torsion spring, the present invention can realize that when the driver does not step on the brake, the roller is in the pop-out state, and when the driver steps on the brake, the roller will be squeezed into the inner groove. During the change of the position of the roller, the toothed disc is always connected to the rolling rotation under the action of the movable rod. This can ensure that the roller will not break the outer bulge, and at the same time, it can ensure that the roller can always provide power for the water flow in the main heat dissipation water tank. (4) By setting up a toothed disc, a first inclined groove, a first push rod, a turntable and a first spring, the present invention achieves that when the truck is in reverse and the brake is applied, the roller rotation will not drive the rotating drum to rotate in the opposite direction through the various structures, thus unloading the momentum of the coil spring.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1-11As shown, the present invention provides a technical solution: an energy-saving brake drum radiator for heavy-duty trucks, comprising an arc block 1, a driven gear 12, a driving gear 13, a main cooling water tank 15, and a cooling connecting groove 16. The arc block 1 includes a top block 101 and a bottom block 102. A mounting plate 8 is provided at the center of the arc block 1, and a connecting device 5 is provided on the left side of the mounting plate 8. The top block 101 and the bottom block 102 are rotatably connected through the connecting device 5. Connecting wheels 9 are rotatably provided at the right ends of both the top block 101 and the bottom block 102. A toggle block 4 is movably arranged between the two connecting wheels 9. An outer drum 2 is fitted on the surface of the arc block 1. Brake pads 3 are provided on the outer surfaces of the top block 101 and the bottom block 102. The driven gear 12 and the driving gear 13 are both located inside the main heat dissipation water tank 15. Through the cooperation of the driven gear 12 and the driving gear 13, a simple gear pump is formed inside the main heat dissipation water tank 15. When the gear pump works, it greatly increases the water flow speed in the main heat dissipation water tank 15 and the heat dissipation connecting groove 16, thereby improving the heat dissipation efficiency.

[0022] Both the top block 101 and the bottom block 102 have heat dissipation grooves 10 and inner grooves 11 inside. The inner groove 11 has a through groove 18 on the right side. The two sides of the through groove 18 have second grooves 37 at their center. A first movable shaft 19 is movably arranged between the two second grooves 37. A roller 17 is sleeved on the surface of the first movable shaft 19. A third groove 40 is opened on the inner walls of both sides of the through groove 18 and on the right side of the second groove 37. A third fixed shaft 39 is fixedly arranged at the center of the third groove 40. A second torsion spring 38 is sleeved on the surface of the third fixed shaft 39. The other end of the second torsion spring 38 is in pressure contact with the end of the first movable shaft 19. The second torsion spring 38 can prevent the roller 17 from breaking the outer drum 2, and can also collect rotational momentum by following the rotation of the outer drum 2, which is the power source of the water flow inside the main heat dissipation water tank 15.

[0023] One side of the roller 17 has an internal tooth 27, and one side of the inner groove 11, below the through groove 18, has a first groove 25. A first fixed shaft 24 is fixedly installed inside the first groove 25. A movable rod 26 is sleeved on the surface of the first fixed shaft 24. The movable rod 26 includes an outer rod 2601 and an inner rod 2602. Multiple fixed posts 57 are provided between the outer rod 2601 and the inner rod 2602, and the outer rod 2601 and the inner rod 2602 are fixedly connected by the fixed posts 57. This ensures the structural stability of the movable rod 26 without affecting... To improve transmission efficiency, a first torsion spring 35 is fitted between the inner rod 2602 and the inner wall of the inner groove 11, and onto the surface of the first fixed shaft 24. The two ends of the first torsion spring 35 are fixedly connected to the inner wall of the inner groove 11 and the end of the inner rod 2602, respectively. The first torsion spring 35 ensures that the gear disc 28 on the movable rod 26 is always in contact with the inner gear 27. A rotating sleeve 59 is fitted through the surface of the first fixed shaft 24, between the outer rod 2601 and the inner rod 2602. A third gear 23 is fixedly fitted onto the other end of the rotating sleeve 59. The other end of 26 is rotatably provided with a second movable shaft 31. The other end of the second movable shaft 31 is fitted with a gear disk 28, which meshes with the internal gear 27. The end of the second movable shaft 31 is fixedly fitted with a turntable 61, and the gear disk 28 and the second movable shaft 31 are rotatably connected through the turntable 61. The surface of the turntable 61 is provided with three first spring grooves 32. The inside of the first spring grooves 32 is provided with a first spring 33 and a first push rod 29. The inner wall of the gear disk 28 is evenly provided with three first inclined grooves 30, and the inner wall of the first inclined groove 30 is connected to the first push rod 29. The pressure contact prevents the roller 17 and the toothed disc 28 from rotating without causing other structures to rotate when the brake is applied while the truck is reversing. The surfaces of the rotating sleeve 59 and the second movable shaft 31 are respectively fitted with the first transmission disc 58 and the second transmission disc 60. The surfaces of the first transmission disc 58 and the second transmission disc 60 are fitted with the transmission belt 36, and the rotating sleeve 59 and the second movable shaft 31 are rotatably connected through the transmission belt 36. In this way, when the toothed disc 28 rotates, the transmission belt 36 can drive the third gear 23 to rotate, thereby driving the rotating drum 20 to rotate.

[0024] A second fixed shaft 34 is fixedly installed near the center of the inner groove 11. A rotating drum 20 is rotatably sleeved on the surface of the second fixed shaft 34. A rotating sleeve 41 is installed inside the rotating drum 20 and through the surface of the second fixed shaft 34. A coil spring 42 and a first gear 21 are respectively sleeved at both ends of the rotating sleeve 41. When the outer body of the rotating drum 20 rotates, it can store force on the other end of the coil spring 42, and the stored force can be released through the other end of the coil spring 42. The other end of the coil spring 42 is indirectly connected to the rotating sleeve 41. The rotating sleeve 41 and the rotating drum 20 are rotatably connected. Thus, the rotation of the rotating sleeve 41 can drive the first gear 21 to rotate, while the rotation of the rotating drum 20 will not affect the rotation of the first gear 21.

[0025] The inner wall of the rotating drum 20 is evenly provided with multiple grooves 43. A rotating ring 45 is rotatably arranged inside the rotating drum 20. The size and shape of the rotating ring 45 are adapted to the size and shape of the inner wall of the rotating drum 20. The other end of the coil spring 42 is fixedly connected to the inner wall of the rotating ring 45. Six fixing grooves 22 are evenly provided on the surface of the rotating ring 45. A second spring 44 and a second push rod 46 are arranged inside the fixing grooves 22. The other end of the second push rod 46 is connected to the inner wall of the groove 43. When the coil spring 42 is overloaded, the rotating ring 45 can rotate inside the rotating drum 20. This can prevent the coil spring 42 from being overloaded and breaking. The surface of the rotating drum 20 is provided with toothed grooves, and the rotating drum 20 is rotatably connected to the third gear 23 through the toothed grooves. The driving gear 13 includes an outer wheel 1301 and an inner wheel 1302. The left end of the inner groove 11 has two sides. A first rotating rod 51 and a second rotating rod 56 are respectively installed through the main water tank 15. The ends of the first rotating rod 51 and the second rotating rod 56 are both installed inside the main water tank 15 and are respectively fitted with an outer wheel 1301 and an inner wheel 1302. The other end of the first rotating rod 51 is fitted with a first bevel gear 52, and the other end of the second rotating rod 56 is fitted with a third bevel gear 54 and a fourth gear 55. The fourth gear 55 is meshed with the first gear 21. A second bevel gear 53 is rotatably installed at the center of the left side of the inner tank 11. The first bevel gear 52 and the third bevel gear 54 are rotatably connected through the second bevel gear 53. By using the first bevel gear 52, the second bevel gear 53 and the third bevel gear 54, the outer wheel 1301 and the inner wheel 1302 can rotate synchronously and in opposite directions. This can ensure that the water flow achieves a circulation acceleration effect within the arc block 1.

[0026] Three second spring grooves 49 are evenly provided on the inner wall of the inner groove 11 and on one side of the rotating drum 20. A third spring 50 and a third push rod 48 are installed inside the second spring groove 49. Three second inclined grooves 47 are evenly provided on one side surface of the rotating drum 20, and the inner wall of the second inclined groove 47 is in pressure contact with the third push rod 48. By utilizing the cooperation of the third push rod 48 and the second inclined groove 47, it can be prevented that after the coil spring 42 has stored force, when the driver releases the brake, the force collected by the coil spring 42 will not be dissipated through the rotating drum 20 itself. There are two main heat dissipation water tanks 15 inside the top block 101 and the bottom block 102, and the two main heat dissipation water tanks 15 are connected by the heat dissipation connecting groove 16 on the right side. An outlet 14 is provided at the left end of the main heat dissipation water tank 15. The system includes an outer port 1401 and an inner port 1402. A first pipe 6 is provided between the outer port 1401 in the top block 101 and the outer port 1401 in the bottom block 102. A second pipe 7 is provided at both the inner port 1402 in the top block 101 and the inner port 1402 in the bottom block 102. The second pipe 7 is directly connected to the inside of the truck's water tank. When the truck driver steps on the brake, the roller 17 contacts and rotates with the outer drum 2. The rotating drum 20 rotates through various transmission structures, thereby collecting the rotation of the roller 17 through the coil spring 42. At the same time, the coil spring 42 also starts to drive the drive gear 13 to rotate through the first gear 21 and other structures, thereby actively pumping water from the water tank and increasing the circulation speed of water in the main heat dissipation water tank 15.
