随着科学技术的高速发展,为了追求汽车的经济性、动力性、安全性、舒适性等指标,汽车在生产制造过程中广泛应用机电一体装置,如电子喷射、自动变速器、制动防抱装置等,从根本上改善了汽车的性能。但汽车在运动过程中,由于受到外界运行条件的影响,汽车各部件发生磨擦,震动,冲击以及受自然因素的侵蚀性,会使汽车的技术状况逐渐变坏,导致动力性能下降,经济性能变差,安全和可靠性能降低,甚至发生事故。因此应根据汽车零件部件磨损的客观规律、定期地对汽车进行清洁、滑润、检查、调整、紧固等维护作业。
With the rapid development of science and technology, in order to pursue automobile economy, power, safety, comfort and other indicators, the car widely used in the manufacturing process of electromechanical devices, such as electronic injection, automatic transmission, brake anti-lock device Etc., fundamentally improve the performance of the car. However, during the movement of automobiles, due to the influence of external operating conditions, friction, vibration, impact and erosion of natural elements of various parts of the automobile cause the technical condition of the automobile to be gradually deteriorated, resulting in a decrease in dynamic performance and a change in economic performance Poor, safe and reliable performance can be reduced, and even accidents. Therefore, should be based on the objective laws of the wear and tear of auto parts, regular cleaning of the car, lubrication, inspection, adjustment, fastening and other maintenance operations.
