[0026] Please see Figure 1-4 This utility model provides a technical solution for a lightweight braking adjustment mechanism:
[0027] Example 1: A lightweight brake adjustment mechanism, including a support 1, a brake unit, and an adjustment unit;
[0028] The braking unit includes a clamp 2 fixedly connected to the top of the support 1. A fixed shaft 3 is rotatably connected inside the clamp 2. A pressure arm 4 is fixedly connected to the outer wall of the fixed shaft 3. A pressure block 5 is provided inside the support 1. A spring 6 is fixedly connected to the bottom of the pressure block 5. The bottom end of the spring 6 is fixedly connected to the inner bottom wall of the support 1. The outer wall of the fixed shaft 3 is in contact with the top of the pressure block 5. A synchronization plate 11 is fixedly connected to the outer wall of the pressure block 5. Two internal threaded sleeves 7 are rotatably connected to the inner wall of the synchronization plate 11. A screw 8 is threadedly connected to the inner wall of each of the two internal threaded sleeves 7. A push plate 9 is fixedly connected to the bottom end of each of the two screws 8. A downward pressing outer edge 701 is fixedly connected to the outer wall of each of the two internal threaded sleeves 7. The bottom of the pressure block 5 is in contact with the top of the two downward pressing outer edges 701.
[0029] The adjustment unit includes a second gear 15 rotatably connected to the outer wall of the pressure block 5, and two gears 14 fixedly connected to the outer walls of the two internal threaded sleeves 7. The two gears 14 mesh with the second gear 15 respectively. Two tongues 12 are fixedly connected to the inner wall of the synchronization plate 11. Slide grooves 13 are opened on the two screws 8 respectively. The two tongues 12 are slidably connected to the inner walls of the two slide grooves 13 respectively. The gear 14 on the right side drives the gear 14 on the left side to rotate through the meshing of the second gear 15.
[0030] Example 2: Based on Example 1, dust covers 10 are fixedly connected to the outer walls of both push plates 9. The dust covers 10 are made of corrugated flexible hoses. The tops of both dust covers 10 are fixedly connected to the bottoms of the supports 1. The outer wall of the internally threaded sleeve 7 contacts the outer wall of the pressure block 5. The outer wall of the internally threaded sleeve 7 is threadedly connected to the outer wall of the pressure block 5. Two circular grooves 111 and one circular groove 112 are opened on the inner bottom wall of the synchronization plate 11. The circular groove 112 is located at the center of the synchronization plate 11. The two circular grooves 111 are symmetrically distributed in the circular grooves. On the left and right sides of the second 112, the inner walls of the two circular grooves 111 are rotatably connected to the outer walls of the two internal threaded sleeves 7, respectively, to support the rotation of the internal threaded sleeves 7. The inner wall of the second circular groove 112 is fixedly connected to the outer wall of the pressure block 5, to fix the synchronous plate 11 on the outer wall of the pressure block 5. The two gears 14 and 15 are rotatably connected to the top of the synchronous plate 11, to drive the two gears to move synchronously. The bottom of the synchronous plate 11 is provided with a sealing ring 16, to provide a sealed cavity for dust prevention inside the whole device.
[0031] In practical use, this utility model provides a lightweight braking adjustment mechanism. The car air chamber pushes the pressure arm 4 to rotate via a push rod, which in turn drives the fixed shaft 3 to rotate and press the pressure block 5 downward. At this time, the pressure block 5 drives the synchronous plate 11 to move downward, and the pressure block 5 abuts against the lower pressing outer edge 701 on the outer wall of the two internal threaded sleeves 7 and moves downward, so that the screw 8 inside the internal threaded sleeve 7 drives the push plate 9 to move downward for braking. When it is necessary to adjust the braking stroke, the right gear 14 is driven to rotate through the meshing of the left gear 14 via the gear 2 15. Under the limiting action of the plate tongue 12 and the slide groove 13, the two screws 8 can extend downward synchronously. This not only achieves a good braking effect and meets the braking needs of the car under various driving conditions, but also achieves the goal of lightweight design. Compared with the traditional complex braking structure, the system structure is simpler, reduces the number of unnecessary parts, reduces production and maintenance costs, and improves the reliability and stability of the entire braking system.
[0032] By incorporating a dust cover 10 and a sealing ring 16, the dust cover 10, made of a corrugated hose, stretches when the push plate 9 moves downward to brake, thus sealing the connection cavity between the support 1 and the push plate 9. Simultaneously, when the pressure block 5 squeezes the screw 8, causing the internal threaded sleeve 7 to move downward, the synchronizing plate 11 squeezes the sealing ring 16, sealing the connection cavity between the synchronizing plate 11 and the support 1. The two work together to seal the expansion joints of different parts of the braking system, forming a tight protective system that ensures the braking system can effectively resist the intrusion of external impurities in various complex working environments, maintain the normal operation of internal components, and thus ensure that the braking system is always in good working condition, providing reliable braking protection for vehicle operation.
[0033] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
