AI Technical Summary
Existing heat-dissipating brake discs have low heat dissipation efficiency, complex structure, insufficient durability, and high maintenance costs. The heat dissipation structure is integrated with the brake disc, and the entire disc needs to be replaced after wear.
The brake disc body is composed of detachable first and second friction components. Water is guided by the flow channels and flow strips to simplify the heat dissipation structure. The components can be disassembled for easy maintenance by fixing screws and slot blocks.
It improves heat dissipation efficiency, reduces failure rate and maintenance costs, extends the service life of brake discs, and simplifies the maintenance process.
