林业拖拉机采用什么样的行走机构比较好,虽然需要考虑各方面的因素,但主要取决于在松软地面上和冰雪地面上的通过性能。本文以国产J50履带式拖拉机和J-80轮式拖拉机为样机,从理论和试验二方面对此进行了研究,用牵引系数和驱动效率作为评价指标。结果认为:在松软地面和冰雪地面上,履带拖拉机通过性较轮式拖拉机为好。 Forestry tractors using what kind of walking mechanism is better, although the need to consider various factors, but mainly depends on the soft ground and the snow on the ground through the performance. In this paper, domestic J50 crawler tractor and J-80 wheeled tractor as a prototype, from both theoretical and experimental aspects of this study, with the traction coefficient and drive efficiency as the evaluation index. The result is that crawler tractors pass better than wheeled tractors on soft ground and ice and snow.
