摘　　要：文章通过对好微汽油车直拉杆的设计,首先简述了转向系统的功能及要求,其次说明了直拉杆的方案设计。在直拉杆的方案设计中详细阐述了直拉杆设计的步骤,在直拉杆总成设计的步骤中详细表述了直拉杆总成的长度设计和结构布置情况。要注意直拉杆布置时,应尽量使拉杆易于制造,弯折小,受力状态好,不易与其他部件产生动态干涉;在动态情况下与其它部件的最小间隙可运用UG三维仿真软件求出轮胎和直拉杆、直拉杆和板簧、板簧和轮胎之间的实际间隙。并对仿真软件求出的间隙与二位作图法求出的间隙进行对比,以求出直拉杆的实际结构外形。最后,要校核新设计的直拉杆在整车上面的性能是否满足总布置设计的要求。The present paper through to the good micro car straight rod design, The paper describes the functions and requirements of the steering system, Second, the straight rod design. In the straight rod scheme design in detail the straight rod design steps, the straight rod assembly design steps in detail the straight rod assembly design of length and structure layout. Attention should be paid to a straight pull rod arrangement, should try to make the rod is easy to manufacture, the bending of small, good stress state, not easily with other components to generate dynamic interferometer; In the dynamic case and other parts of the minimum clearance can use UG 3D simulation software for tire and a straight rod, a straight pull rod and spring, spring and between the tire and the actual gap. And the simulation software to find out the gap and the two gap mapping method were compared, in order to calculate the straight rod and the actual structure shape. Finally, to check the new design of the straight rod in vehicle above performance can meet the requirements of general layout design. Steering system Straight rod assembly Strength checking.
