Description

Technical Field

[0001] This patent relates to the field of brake drums, specifically a lightweight brake drum device. Background Art

[0002] Brakes are components in the braking system that generate braking force to hinder the movement or movement trend of a vehicle. Except for various retarders, automobile brakes are almost all friction brakes that use the friction between the working surfaces of fixed elements and rotating elements to generate braking torque. The rotating element in the friction pair of drum brakes is the brake drum, and its cylindrical inner surface is the working surface; braking is achieved by pressing the brake pad against the brake drum. However, in current brake drum devices, the friction parts on the brake pads are fixedly installed on the brake pads, and due to long-term friction with the inner surface of the brake drum, there will be wear and tear, and it is not convenient to remove and replace.

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the contents of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to the application.

[0022] See also Figure 1-4This is a schematic diagram of the structure of the patent, a lightweight brake drum device, including a brake drum 1, a brake pad 6 and a friction member 11. The main body of the brake drum 1 is a light alloy material (such as aluminum alloy, etc.), and a cast iron lining is inserted into the inner lining. This brake drum is not only small in weight, but also has good heat dissipation. It is mostly used in cars to achieve a lightweight effect. The brake pad 6 is placed in the brake drum 1, and the friction member 11 is installed on the brake pad 6 through a clamping structure 4;

[0023] The number of the clamping structures 4 is not less than five, and the clamping structures 4 are distributed in an annular shape and equidistantly between the brake pad 6 and the friction member 11, and the clamping structure 4 includes a clamping block 401, a clamping groove 402 and an elastic member 403;

[0024] The block 401 is installed on the friction member 11, the slot 402 is opened on the brake pad 6, and the elastic member 403 is installed in the block 401. The elastic member 403 is made of steel sheet, has elasticity, and enhances the elasticity of the block 401. The block 401 is clamped in the slot 402. During the braking process, the brake pad 6 with the friction member 11 is tightly attached to the inner surface of the brake drum 1 to realize the braking work of the car. Periodically, the friction pad 11 is pulled, and the friction pad 11 is taken out of the slot 402 on the brake pad 6 with the block 401, so that the friction pad 11 is removed from the brake pad 6, which is convenient for the replacement of the friction member 11.

[0025] A fixing member 5 is installed in the brake drum 1, and a brake pad 6 is rotatably installed on the fixing member 5 through a rotating member 12. The rotating member 12 is composed of a first threaded hole 13, a through hole 14, a second threaded hole 15 and a threaded rod 16;

[0026] The first threaded hole 13 is formed on the ear plate on one side of the fixing member 5, the through hole 14 is formed on the brake pad 6, and the second threaded hole 15 is formed on the ear plate on the other side of the fixing member 5. The threaded rod 16 is sleeved in the first threaded hole 13, and the threaded rod 16 passes through the through hole 14. The position where the threaded rod 16 passes through the through hole 14 is not threaded, and the threaded rod 16 is sleeved in the second threaded hole 15. During the installation process, the brake pad 6 is placed between the ear plates on both sides of the fixing member 5 in the brake drum 1, and the threaded rod 16 is screwed into the first threaded hole 13, and passes through the through hole 14 on the brake pad 6, and is screwed into the second threaded hole 15 at the same time. When braking, the brake pad 6 rotates on the fixing member 5 through the threaded rod 16.

[0027] A hook 7 is installed on the brake pad 6, and a spring 8 is hung on the hook 7. The spring 8 is hung on the hook 7 on the brake pad 6. During the braking process, the brake pad 6 rotates outward and the spring 8 stretches. Conversely, the brake pad 6 can be reset by the elasticity of the spring 8.

[0028] A drum brake 9 is installed in the brake drum 1. The model of the drum brake 9 is 001. A hose 10 is connected to the drum brake 9. The output end of the drum brake 9 contacts the brake pad 6. The output end of the drum brake 9 applies force to the brake pad 6 toward the outside.

[0029] The brake drum 1 is provided with an axial hole 2 for mounting the axle of the vehicle wheel. The brake drum 1 is provided with mounting holes 3, the number of which is not less than four, which are equidistantly distributed in a circular shape on the brake drum 1, and the brake drum 1 is mounted on the vehicle wheel through the mounting holes 3.

[0030] When the present invention is working, the brake drum 1 is mounted on the vehicle wheel through the mounting hole 3, and the axle hole 2 is used to mount the axle of the vehicle wheel. When the vehicle brakes, the foot is pressed on the brake, and the hydraulic brake pushes the brake oil out of the master cylinder and enters the hose 10, and then the pressure is transmitted from the brake pedal to the drum brake 9. At this time, the output end of the drum brake 9 gives the brake pad 6 an outward force, and the brake pad 6 rotates outward on the fixing member 5 through the threaded rod 16. The brake pad 6 and the friction member 11 are tightly attached to the inner surface of the brake drum 1, thereby realizing the braking operation of the vehicle. During the process, the spring 8 is stretched, and conversely, the brake pad 6 can be reset by the elasticity of the spring 8. Periodically, the friction plate 11 is triggered, and the friction plate 11 is taken out of the card slot 402 on the brake plate 6 with the card block 401, so that the friction plate 11 is removed from the brake plate 6, which is convenient for the replacement of the friction member 11. When the threaded rod 16 is screwed in the reverse direction, the threaded rod 16 is screwed out of the second threaded hole 15 on the fixing member 5, and then moved out of the through hole 14 on the brake plate 6, so that the spring 8 is removed from the hook 7, and the brake plate 6 can be disassembled for replacement.
