轮胎式铲土运输机械由于运转方便灵活和多种用途,而得到迅速发展。近年来,我国的铲土运输机械,特别是轮式装载机,发展较快,成为施工现场常用的机械。高速行驶的地面车辆,为降低车身的振动一般设有悬挂系统。但装载机、平地机等的车速不是很高,由于作业要求以及为简化结构、降低成本,多不设悬挂系统。然而它们却经常在比较恶劣的条件下作业,在较差的路面上运行。这样减振性能不良的结构却受到比较强烈
The tire-type shovel transportation machinery has been rapidly developed due to its convenient and flexible operation and various uses. In recent years, China’s shovel transportation machinery, especially wheel loaders, has developed rapidly and has become a common machine for construction sites. Ground vehicles traveling at high speeds generally have a suspension system to reduce the vibration of the vehicle body. However, the vehicle speeds of loaders, graders, etc. are not very high. Due to operational requirements and to simplify the structure and reduce costs, no suspension system is provided. However, they often operate under harsh conditions and run on poor roads. This structure with poor damping performance has been relatively strong
