四轮驱动拖拉机的发展,提出了从本质上系统地阐明其动力传递特点的某种理论必要性。而其目的,则不外是为了正确地设计这种拖拉机和合理地使用这种拖拉机。 本文从一般四轮驱动拖拉机前后轮运动不协调的最基本表现——滑转、滑移值的不同着手,较详细地分析了设计和使用过程中应遵循的理论指导原则,并提出一些建议。与此同时,在铰接式拖拉机上,还应注意铰接点位置的选择会对拖拉机的行驶直线性和转向过程动力传递的特点带来影响。
The development of four-wheel-drive tractors proposes some theoretical necessity to clarify systematically the characteristics of power transmission. Its purpose, however, is nothing less than the correct design of such tractors and the rational use of such tractors. This paper starts with the difference of the most basic manifestation of the uncoordination of the front and rear wheels of a typical four-wheel-drive tractor, and analyzes in detail the theoretical guidelines to be followed in the design and use of the tractor, and puts forward some suggestions. At the same time, on articulated tractors, it should also be noted that the choice of articulation point position will have an impact on the tractive driving straightness and the power transfer characteristics of the steering process.
