Our company Ou Liangyou Master Yu2025Year11In August, he went to Cuba to provide guidance on passenger car maintenance and successfully completed his mission and returned home
Cuban customers we cooperate with have feedback that during long-term operation of many Foton buses they purchased, due to special local climate and road conditions, problems such as abnormal chassis sound, reduced braking performance, and poor air conditioning and cooling effect have occurred, which seriously affected the normal dispatch of vehicles. Customers submit urgent maintenance needs. Mission goals: Quickly locate and resolve existing vehicle faults and restore safe operating status of vehicles; optimize vehicle configuration based on Cuban road conditions and climate characteristics; provide systematic training to customer technicians to reduce the incidence of subsequent failures.
After the maintenance team arrived at the scene, it carried out a comprehensive investigation with customer technicians, combined with vehicle operation records and driver feedback, and determined that the main fault types and causes were as follows: chassis and suspension system failures During driving, the chassis has obvious abnormal noise, and the body shakes greatly. Cause leakage of suspension system shock absorbers and wear of bushings; The chassis bolts are loose due to long-term bumps. The brake system has a slow response. The braking distance is extended. The air humidity is high. The inner wall of the brake pipeline is corroded. The brake pads are seriously worn. The air conditioning system is not replaced in time. The cooling effect is poor. The air outlet air volume is insufficient. Dust and mosquito impurities adhere to the condenser surface, which reduces heat dissipation efficiency; the air conditioning filter element is seriously blocked
For complex overseas road conditions and climatic conditions, it is necessary to fully investigate before maintenance and prepare sufficient wearing parts in advance to avoid delays in the construction period due to shortage of spare parts. The maintenance plan needs to be flexibly adjusted based on the actual local working conditions, taking into account fault repair and vehicle performance optimization, and improve customer satisfaction.
