Description

Technical Field

[0001] This application relates to the field of automotive brake pipe protection technology, and more specifically, to an anti-wear protection structure for automotive brake pipes. Background Technology

[0002] Brake hoses in a car are components used in the car's braking system. Their main function is to transmit the braking medium during braking, ensuring that the braking force is transmitted to the brake shoes or brake calipers to generate braking force, thus making the braking effective at all times.

[0003] In related technologies, to address the issue that automotive brake lines often experience temperature increases during use due to prolonged exposure to hydraulic oil and braking forces, which can easily lead to softening and severely impact their lifespan, a patent with publication number CN213768519U provides an automotive brake line with a reasonable structural design, high stability, high strength, strong wear resistance, and good heat dissipation. This effectively reduces safety hazards during vehicle operation and has promising market application prospects.

[0004] Although the existing technical solutions mentioned above make the brake pipe more wear-resistant and have higher stress strength by utilizing the outer tube layer and the plastic shell layer, thus effectively extending the service life of the brake pipe, the connection between the outer tube layer and the plastic shell layer is not tight enough and the toughness is poor. Long-term bending will affect the service life, make it inconvenient to buffer the brake oil pipe of the car, and affect long-term use.

[0005] In view of this, we propose an anti-wear protection structure for automotive brake lines. Utility Model Content

[0006] The purpose of this application is to provide an anti-wear protection structure for automotive brake pipes, which can effectively solve the problems in the prior art where the connection between the outer tube layer and the plastic shell layer is not tight enough, the toughness is poor, the service life is affected by long-term bending, and it is inconvenient to buffer the automotive brake oil pipe, thus affecting long-term use.
