1、前言随着摩托车工业的发展,摩托车的车架逐渐由管式替代了板式。而轻骑生产的车架,90％多的设计是管式结构。管式车架的特点是结构复杂,其大多数组件为空间结构,因此在车架的三视图上,大多数组件的投影与轴的夹角为投影角,不反映其倾角。设计车架焊胎时,投影角和倾角都要用到,即焊胎在长度方向(X方向)和宽度方向(Y方向)上的限
1, Foreword With the development of the motorcycle industry, the motorcycle frame gradually replaced by the tube plate. The Qingqi production frame, more than 90% of the design is the tube structure. Tubular frames are characterized by a complex structure, most of which have a spatial structure, so the projection of the most components on the three views of the frame is the projection angle and does not reflect the inclination. When designing frame welding, the projection angle and inclination must be used, that is, the limit of the welding rod in the length direction (X direction) and the width direction (Y direction)
