从设计流线角度出发对变矩器传统三圆弧循环圆提出改进方法,简化了设计流程,指出由于经验公式的过约束导致其宽度不可调。通过对设计流线的分析,提出一种可调宽度循环圆模型,并进行了实例设计。 From the point of view of design streamline, an improved method is proposed for the traditional three circular arc circle of torque converter, which simplifies the design process and points out that its width is not adjustable due to the overconstraints of the empirical formula. Through the analysis of the design flow line, a circular model with adjustable width is proposed, and a case design is carried out.
