Description

Technical Field

[0001] This utility model belongs to the field of pipe technology, and more specifically, relates to a square wear-resistant textile pipe for aluminum exhaust pipes in new energy vehicles. Background Technology

[0002] In the application of aluminum busbar assemblies in new energy vehicles, the pipes, as key components for fluid transmission, must withstand complex operating conditions such as high-frequency vibration, temperature changes, and contact with chemical media. Existing aluminum busbar pipes mostly adopt a circular cross-section structure, and their wear-resistant design is usually achieved by externally wrapping a wear-resistant layer. However, the following technical limitations exist: The fit between traditional circular pipes and wear-resistant sleeves has limited precision and often requires fasteners or adhesives for fixation. The installation process relies on tools and is prone to displacement risks. The wear-resistant sleeves lack effective fixing structures at both ends, making them prone to loosening under vibration or tension, leading to a decrease in wear resistance. The choice of wear-resistant layer materials is limited and it is difficult to simultaneously meet the requirements of low friction coefficient, corrosion resistance, and long-term wear resistance.

[0003] Specifically in this technical field, existing aluminum pipe systems have shortcomings in terms of adaptability to rectangular cross sections, stability of wear-resistant sleeve positioning, elastic adaptive adjustment, and optimization of the comprehensive performance of the wear-resistant layer. These shortcomings lead to problems such as accelerated wear, loose joints, high maintenance frequency, and shortened service life in complex working conditions. Utility Model Content
