汽车前轮采用独立悬挂时,悬挂机构与转向拉杆的运动轨迹,必须协调一致。若杆件尺寸选择不当,必然会发生运动轨迹的干涉,从而影响汽车的操纵稳定性。因此,合理地选择各杆件的长度,即正确确定各铰肖的位置,是十分重要的。本文介绍Bobillier定理,利用该定理能够合理地选择转向拉杆或悬挂机构的铰肖位置,使转向拉杆机构与悬挂机构不仅在直线行驶时,而且在转向时,都不发生运动轨迹的干涉,这就大大地提高了汽车的操纵稳定性。由于目前介绍的有关Bobillier定理的一些内容,为“平面机构综合”一书,不太便于一般工科读者阅读。为此,本文对该定理稍加改动,作了适合于一般工科读者的阐述和证
When the front wheel of a car adopts independent suspension, the movement track of the suspension mechanism and the steering rod must be coordinated. If the rod size is not properly selected, the movement path will inevitably occur interference, thus affecting the stability of the car’s handling. Therefore, a reasonable choice of the length of each rod, that is, the correct positioning of each hinge Shaw is very important. In this paper, the Bobillier theorem is introduced. By using this theorem, we can select the hinge position of steering rod or suspension mechanism rationally so that the steering rod mechanism and suspension mechanism do not interfere with the trajectory of motion not only in straight line but also in steering direction Greatly improve the car’s handling stability. Due to the present introduction of some of Bobillier’s theorems, it is not easy for general engineering readers to read the book “Comprehensive Plane Organization”. To this end, this article a little change to the theorem, made suitable for general engineering readers and testimony
