近些年来,在各级领导的重视下,在公路运输技术管理部门的努力工作下,强化了二级维护工作,使这项工作在各级领导和企业法人及车主,驾驶员心目中得到了重视,取得一些成绩。但总的来看这种重视程度还不够,按期进保率、维护质量、二级维护工作的管理等方面仍然存在一些问题。如何加强车辆二级维护工作、保持车辆良好的技术状况,保证安全运输,取得最佳的经济效益和社会效益是当前急待解决的问题,就此谈一点看法。一、二级维护的作用汽车各部总成和零部件在使用过程中,由于结构工艺因素(如结构形式、所用材料及加工质量)、使用条件(如载重量、行驶速度、道路、气候、燃润料品质、驾驶技术、维修质量)的影响,产生不同程度的磨损,使原来的静配合松动,动配合间隙增大,产生化学腐蚀,润滑油条件变坏,甚至发生机
In recent years, under the attention of leaders at all levels, under the hard work of the road transport technology management department, the second-level maintenance work has been strengthened so that this work has been well received by leaders at all levels, corporate entities and vehicle owners and pilots Attention, and achieved some results. However, in general, this level of emphasis is still not enough, and there are still some problems in maintaining the rate of insurance on schedule, maintaining the quality, and managing the secondary maintenance work. How to strengthen the secondary maintenance of vehicles, maintain the good technical condition of the vehicles, ensure the safe transportation, and obtain the best economic and social benefits are the most urgent problems to be solved. The role of a secondary maintenance Automotive components and parts of the various components in the course of use, due to structural factors (such as structural form, materials used and processing quality), conditions of use (such as load, speed, road, climate, combustion The quality of the material, the driving technology, the quality of the maintenance), the wear and tear of different degrees will be produced, the original static fit will be loosened, the dynamic fit will increase, the chemical corrosion will occur, the condition of lubricating oil will deteriorate,
