重型车电涡流缓速器的结构设计 摘要 安全是现代汽车的发展方向。电涡流缓速器作为辅助制动器的一种，主要安装在车身底盘下面的传动轴上，他是把汽车行驶时的动能通过传动轴上的缓速器转化为热量而散发掉，从而实现汽车的减速和制动。电涡流缓速器主要应用于重型车和大型客车（公交车）的缓速制动、频繁以及长时间制动，他可以使车轮制动器的温度大大降低，保证制动蹄片处于良好的技术状态。电涡流缓速器能够承担50%~90%的制动工作，将会是汽车必不可少的配备装置之一。 本文首先对电涡流缓速器的制动力矩进行推导，给出了具体的计算公式，并计算出所设计的电涡流缓速器的制动力矩和制动功率。其次结合现实生活实际应用和参照相关技术参数，对电涡流缓速器进行了整体装配以及转子、定子、法兰、花键轴、固定架及挡环等主要零部件的设计，包括外型尺寸、结构和材料等。最后对电涡流缓速器的缓速制动效果、热容量和温升进行了校核，通过计算所设计的结构和尺寸能够满足要求，得到一个较合理的结构设计。 关键词：电涡流缓速器；制动；结构设计 Structural Design on Eddy Current Retarder of Heavy-duty Vehicle Abstract Security is the development tendency of the modern automobile. The electricity turbulent flow slow fast achievement assists the brake one kind, mainly installs on the chassis following drive shaft, he is goes the time kinetic energy the automobile to send out through the drive shaft on slow fast transformation for the quantity of heat, thus realizes the automobile deceleration and the brake. The electricity turbulent flow slow fast mainly applies in the heavy vehicle and the large-scale passenger train (public transportation) the slow fast brake, frequent as well as the long time applies the brake, he may cause the wheel brake the temperature to reduce greatly, guaranteed the brake shoe is at the good technical condition.The electricity turbulent flow slow fast can undertake 50%~90% brake work, could be one of automobile essential equipment installments. This article first carries on the inferential reasoning to the electricity turbulent flow slow fast braking moment, has given the concrete formula, and calculates the electricity turbulent flow slow fast braking moment and the braking power which designs. Next union real life practical application and the reference related technical parameter, slow fast has carried on the whole assembly as well as the rotor, the stator, the flange, the spline shaft, the bracket fixing and the retainer to the electricity turbulent flow and so on the main spare part design, including outlook size, structure and
