货车可靠性主要取决于下述因素:货车零部件的强度和寿命、制造质量所应有的水平与稳定性、结构是否符合其运用条件。车辆制造厂、全苏车辆科学研究院以及其他铁路运输单位在现造车辆的改造方面,做了大量工作。轮对从1948年起,货车的车轴采用苏联国家标准 4007-48。该标准规定干线货车统一采用Ⅲ型车轴和滑动轴承,允许的最大轴重为20.5吨力,这个载荷规定一直保留到1959年。然而在这一段时间内,主型货车的实际轴重(18.0～20.5吨力),低于允许值。 1959年,货车车轴采用了新标准( -
The reliability of a truck mainly depends on the following factors: the strength and life of the truck parts, the level and stability of the manufacturing quality, and whether the structure meets the conditions for its application. Vehicle manufacturers, All-Soviet Academy of Vehicle Science and other rail transport units in the reconstruction of existing vehicles, has done a lot of work. Wheelset Since 1948, the truck’s axles have adopted the Soviet Union national standard 4007-48. This standard stipulates that the trunk truck should adopt the type Ⅲ axle and the sliding bearing uniformly, and the maximum allowable axle load is 20.5 tons. The load regulation has been kept until 1959. However, during this period of time, the actual axle load of the main van (18.0-20.5 tonne) is below the allowable value. In 1959, the truck axle with a new standard (-
