AI Technical Summary
The existing bolt sleeves and bolts have insufficient stability in their connection, making them prone to slippage. Furthermore, the lack of effective shock absorption measures leads to hand fatigue and potential injury for maintenance personnel.
A bolt sleeve for automotive brakes has been designed, including anti-slip grooves, elastic blocks, and a shock-absorbing mechanism. The anti-slip grooves improve the fit with the bolt head, and the elastic rubber layer and damper absorb vibrations, reducing the transmission of vibrations to the hand.
It improves the connection stability between the bolt sleeve and the bolt head, reduces vibration transmission to the hands, reduces maintenance personnel fatigue, and ensures operational stability and safety.

Brake system, as a key component of safe driving of automobiles, is directly related to the safety of drivers and passengers. During the entire service life of the automobile, the brake system needs to be regularly maintained and repaired to ensure that it is always in good working condition. In the maintenance and repair work of the automobile brake system, the disassembly and installation of the bolt is a common and important operation. The bolt in the automobile brake system is used to fix the brake disc, brake pad, brake caliper and other key components, which bear huge frictional force and impact force during vehicle driving. Therefore, the connection of the bolt must be firm and reliable. When repairing the brake system, special tools are needed to disassemble and install these bolts, and the bolt sleeve for automobile brake is one of the indispensable important tools.
[0003] However, the connection stability between the existing bolt sleeve and the bolt needs to be improved. In the process of disassembly and installation of the bolt, the sleeve needs to be closely matched with the bolt head to ensure that the torque can be effectively transmitted. However, the adhesion of some existing sleeves to the bolt head is not enough, and the sleeve is mostly designed with rigid structure, lacking effective shock absorption measures. When a large impact force and vibration occur between the sleeve and the bolt, these vibrations will be directly transmitted to the hands of the maintenance personnel, which can easily cause hand fatigue and even cause hand injury, thereby reducing the practicability of the bolt sleeve.
