ADAMS+solidworks锁环式同步器的设计及运动仿真+CAD图纸

摘要同步器的应用可避免变速器换挡时接合齿端部的冲击磨损，实现迅速、无噪声的换挡，有利于减轻驾驶员的劳动强度，也降低了对换挡的技术要求。

同步器分别为三种同步器：常压式、惯性式、惯性增力式。常压式同步器的结构简单，但它的缺点是不能保证啮合齿在同步状态下换挡，现在已经不用。现惯性同步器得到广泛应用。惯性式同步器也是依靠磨擦作用来实现齿轮同步转动的，惯性式同步器上面设有专设机构以此来保证接合套与待接合的花键毂在未达到同步之前不可能接触，从而避免了齿间撞击。本文主要完成轿车变速器中同步器的设计。文中，首先根据同步器经验公式的计算，确定锁环式同步器各零件的主要尺寸，以及各零件之间在设计计算中的关系式；然后校核同步器设计中的诸多参数，确定锁环式同步器的基本几何参数和装配位置参数；最后采用solidworks软件完成同步器的三维建模。最后通过ADAMS对已完成的同步器进行运动仿真及动力学分析。52550

Abstract

Because synchronous transmission shift can be avoided when the impact of the end of the engagement tooth wear, to achieve rapid, noiseless shift will help reduce the driver's labor intensity, but also reduces the technical requirements for the shift.

Synchronizers have atmospheric type，inertial type and inertia increase strength type. Atmospheric type synchronizer structure simple, but have not guarantee in synchronization condition of meshing pieces of faults，has no shift. Of widely used is inertial type synchronizer. Inertial type synchronizer depend on friction role in achieving synchronization with above them exclusively institutions guarantee of engagement with the spine tooth circle for engagement in inaccessible synchronism could not contact before between so as to avoid the tooth impact. It mainly designs Santana mechanical transmission synchronizer in this paper. Firstly, the synchronizer ring main parameters are determined by the relevant calculation formula. Then check many parameters in the design of synchronizer, make sure the lock ring synchronizer of basic geometric parameters and assembly location; Finally using solidworks 3 d modeling software to complete the synchronizer. Finally through ADAMS completed synchronizer for motion simulation and dynamic analysis.
