Description

Brake and noise reduction structure Technical Field The utility model belongs to the field of braking equipment, and particularly relates to a brake and a noise reduction structure. Background A brake is a mechanical device that can slow down, stop, or maintain a stopped state of a moving part (or moving machine), and noise problems may occur when a part of the brake is operated. During braking, the brake pads may rub vigorously, thereby generating high frequency vibrations and causing noise. To solve this problem, a conventional method is to add a lubricant to the surface of the brake pad to reduce the vibration amplitude by reducing the friction coefficient, thereby reducing noise. However, the addition of the lubricant affects the braking effect, and the lubricant is degraded in lubrication performance even if it is carbonized and failed under a high temperature environment, resulting in poor noise control effect. Meanwhile, with frequent use of the brake, the lubricant is gradually lost and needs to be periodically replenished or replaced, which not only increases the maintenance cost, but also can influence the noise reduction effect due to untimely maintenance. In addition, some brakes may employ a thickened brake pad or disc to provide a desire to dampen vibrations by increasing the structural mass. However, this approach can lead to an increase in the overall mass of the brake, not only increasing the energy consumption, but also possibly affecting the handling performance of the device, and the thickened structure limits to a certain extent the application scenarios of the brake, which are difficult to adapt to spatially compact devices. There is a need to propose a new structure for solving the above technical problems.
