[0003] The automotive brake pipe connection structure is a key component to ensure the normal operation of the braking system. It is responsible for transmitting brake fluid or high-pressure gas to achieve the braking force control of the wheels. The brake pipe is usually composed of a brake hard pipe and a brake hose. The brake hard pipe is rigidly connected to the vehicle body, while the brake hose is arranged on the frame to adapt to the dynamic changes during vehicle driving. The design of the automotive brake pipe connection structure has been continuously evolving to meet the high standards of modern automotive safety and reliability. Today, with the continuous development of various aspects of automobiles, the braking performance of automobiles directly affects the performance of automobiles and the safety of passengers. The automotive brake pipe connection structure directly affects the braking performance of automobiles. Most connection structures of automotive pipes use hydraulic systems.
