拖拉机悬挂机构设计一般有如下四个步骤: 1.根据农具联结尺寸类别,按照国家有关标准选取悬挂轴离地高度、立柱高度、悬挂轴提升行程、下悬挂点间距等尺寸。 2.根据在拖拉机上布置的可能性,初步选定杆件与拖拉机机体的联接点位置及杆件长度,再确定农具在纵向平面和水平平面的瞬时转动中心——瞬心。确定瞬心位置时应
Tractor suspension mechanism design generally has the following four steps: 1. According to the size of the tool coupling size, in accordance with the relevant national standards selected suspension shaft height from the ground, the height of the column, the suspension shaft to enhance the stroke, the spacing under the suspension point and other dimensions. 2. According to the possibility of arrangement on the tractor, initially select the joint position of the rod and the tractor body and the length of the rod, and then determine the instantaneous center of rotation - instantaneous center of the agricultural tools in the longitudinal plane and the horizontal plane. Determine the instantaneous heart position should be
