1、 I 摘要 取力器是专用车辆上的重要组成部分，是专用车辆能实现其专用功能的动力 来源。取力器的质量好坏，严重影响专用车辆的试用状况。取力器一般情况下安 装在变速器上。 通常取力器是一种齿轮传动装置，其主要功用全部或部分的是取出变速器所 传递的动力， 或直接将发动机的功率通过法兰和传动轴传递到被驱动的工作机上， 使汽车实现特有的专用功能。 本次毕业设计设计的取力器是与 CA1061K28L3 型载货汽车变速箱相配合的 取力器。在设计过程中，取力器的动力是由变速箱中间轴输入的。利用斜齿轮， 与变速箱中间轴上的斜齿轮啮合获得动力，由两直齿轮啮合，以及接合套，同步 器等的应用，将力传递到输出轴上。最后
2、，由输出轴通过内外花键配合，将力传 递到下一级机械机构上。 在确定了基本结构和给定的数据基础上,确定传动比,设计两轴中心距,轴的直 径,进一步算得啮合齿轮的基本参数,进而对齿轮和轴进行校核，同时对轴承进行了 选择。在设计过程中，利用CAXA绘图，运用MATALAB软件编程。 通过本次设计，使所设计的取力器工作平稳可靠，传动效率良好。 关键词：汽车；取力器；同步器；双联齿轮。 II Abstract There is a special vehicle is the important component of the special vehicles can realize its funct
