AI Technical Summary
The existing service brake and parking brake of tanks and armored vehicles are two separate control mechanisms, which results in a large braking system space occupation, complex parts and high cost, making it difficult to simplify the braking control structure and improve maintenance performance.
Design a mechanically integrated service brake and parking brake device. Through an innovative combination of components such as brake shaft, support, foot pedal, parking bracket, and parking lever, the service brake and parking brake share a common linkage system, eliminating the separate brake linkage system for the parking brake and integrating it into the cockpit for operation.
It saves installation space, reduces parts by 30%, simplifies the structure, improves maintenance performance, increases fault visibility, and makes maintenance more convenient.
