【摘要】：差速器是工程载重汽车中的关键部件。差速器用于汽车驱动桥对两车轮转速和力矩的分配。目前大多数差速器，只能将转速按需分配给两轮，力矩平均分配给两轮。而强制锁止式差速器也只能在一轮打滑的情况下将两轮轴锁住，使差速性能失效。国外有一种自由轮式差速器，快速轮与传动系统完全脱开成为自由轮，该差速器的特点是初步具备差力特性，其缺点也显而易见。根据现有国内外差速器的不足，，本课题研制的新型差力差速器能最大的利用路面附着力驱动车辆，其通过能力强，运行平稳可靠，结构较简单。可以通过车辆驱动桥主减速器及桥壳的结构调整它的尺寸大小，从而实现与现有差速器互换使用，是普通锥齿轮差速器的理想替代产品，有着广大的市场应用前景。本文选取ZL-80型轮式装载机为仿真研究对象，对轮式装载机以及差速器的国内外研究现状进行了简要介绍，分析了差力差速器结构特征和工作原理，并基于电子图板CAXA软件和三维建模软件SolidWorks参数化建模后完成了差力差速器三维模型。本文介绍了虚拟样机技术和ADAMS软件，通过SolidWorks和ADAMS软件之间的数据交换，将交换后的模型进行修改后，添加约束和驱动，完成差力差速器虚拟样机模型的建立。通过ADAMS虚拟样机仿真软件，根据ZL-80型轮式装载机在四个典型的路面上直驶和转弯时的工况下，设置不同的仿真参数，完成差力差速器的运动学及动力学分析，通过对仿真结果的分析可以证明设计的差力差速器模型的正确性以及其功能的正确性。通过本课题的研究，不仅为ZL-80型轮式装载机驱动桥设计了一套新型的差速器，并且是利用虚拟样机技术设计工程机械设备的有益尝试，从而也为进一步为开发新型高效的工程机械设备提供了一种新思路新方法。
[Abstract]:Differential is a key component in engineering truck. Differential is used to distribute the speed and torque of two wheels on the drive axle of the automobile. At present, most differential speed can only be distributed to two wheels according to their needs. The torque is equally distributed to two wheels, and the forced locking differential can only lock the two axles in the case of one wheel slip, which makes the differential performance invalid. There is a kind of free wheel differential in foreign countries. The fast wheel and the transmission system are completely detached into the free wheel. The characteristic of the differential is that it has the characteristic of differential force initially, and its shortcomings are obvious, according to the deficiency of the existing domestic and foreign differential. The new differential differential can drive the vehicle with the greatest road adhesion, which has strong passing ability and stable and reliable operation. The structure is simple. The size of the main reducer and the axle housing can be adjusted by the structure of the drive axle main reducer and the axle housing, which can be used interchangeably with the existing differential. It is an ideal substitute for the ordinary bevel gear differential. Has the broad market application prospect. In this paper, ZL-80 wheel loader is selected as the simulation research object, the research status of wheel loader and differential loader at home and abroad is briefly introduced, and the structure characteristics and working principle of differential force difference are analyzed. Based on CAXA software of electronic drawing board and SolidWorks of 3D modeling software, the differential differential 3D model is completed. This paper introduces the virtual prototyping technology and ADAMS software. Through the data exchange between SolidWorks and ADAMS software, the model is modified and the constraint and driver are added. The virtual prototype model of differential differential is established. The simulation software of ADAMS virtual prototype is used to set different simulation parameters according to the working conditions of ZL-80 wheel loader under four typical road conditions. The kinematics and dynamics analysis of differential force differential is completed. The correctness of the designed differential force differential model and its function can be proved by analyzing the simulation results. Through the research of this subject, not only a set of new differential is designed for the drive axle of ZL-80 wheel loader, but also a useful attempt to design construction machinery equipment by using virtual prototyping technology. It also provides a new way of thinking and new method for the development of new and efficient construction machinery and equipment.
