Forgings are one of the core components of automobiles, and their performance directly affects the safety and economy of vehicles. To ensure the long-term stable operation of forgings and extend their service life, correct maintenance is essential. This article discusses the maintenance methods of forgings for new energy vehicles from the perspectives of national policies and actual production, with specific examples.
From the perspective of national policies, the Chinese government has established various standards and regulations, requiring regular inspection and maintenance of forgings for new energy vehicles. “Forged Aluminum Alloy Parts for New Energy Vehicles” (GB/T 32237-2015) specifies the inspection cycle and standards for forgings and corresponding cleaning and coating maintenance methods. Moreover, the automotive industry standard QC/T 464-2018 “Technical Specification for Automobile Electronic Control System Maintenance” stipulates that in addition to simple maintenance of cutting surfaces and forging surfaces, maintenance of forgings for new energy vehicles should also focus on anti-corrosion and maintenance of areas prone to oxidation and foreign object intrusion, such as punching and threading, requiring appropriate cleaning agents and lubricants for maintenance.
In actual production, the maintenance of forgings for new energy vehicles differs depending on the selected materials and production processes. For example, for aluminum alloy forgings, clean, soft cloths with an appropriate amount of ammonia should be used to wipe the surface, avoiding the use of cleaning agents containing acidic or corrosive substances. For titanium alloy forgings, striking, collision, and scratching should be avoided during operation, to prevent surface scratches or serious vibration that may affect the surface quality and performance, and timely repair.
In actual maintenance, attention should be paid to the stress status of the forgings, dust and foreign object intrusion. Some car owners do not pay much attention to the detailed cleaning of the surface, which is prone to accumulation of dust and foreign objects, causing vibration noise and other problems. Therefore, during routine driving, car owners should regularly check the forgings to ensure that there are no structure defects or deformation conditions, while paying attention to cleaning and maintenance, reducing wear and damage of forgings, and improving their service life.
Overall, the maintenance of forgings for new energy vehicles is a comprehensive work that requires government regulations and continuous innovation and improvement in actual production. Only when all aspects are done well can the safety and economy of new energy vehicles be truly guaranteed.
