【摘要】：文章针对后轮驱动轮式摊铺机牵引力不足的缺陷，通过对轮式摊铺机不同驱动方案的分析，确定在后轮驱动的基础上增加前轮驱动系统，对全轮驱动液压系统方案进行了研究。文章主要对以下几方面的工作内容进行了阐述： 1.采用理论分析、计算机仿真和试验相结合的研究方法，对轮式摊铺机结构原理及其作业过程进行了深入分析。 2.通过对几种不同前轮驱动系统的比较研究，确定了采用远程恒压控制变量泵系统为前轮驱动液压系统方案。 3.对全轮驱动摊铺机行驶驱动液压系统进行了设计计算，完成了主要零部件选型。 4.建立了全轮驱动摊铺机行驶系统仿真模型，对轮式摊铺机的牵引性能、起步加速过程、顶推料车起步过程等进行了仿真。其仿真结果表明：增加前轮驱动液压系统后，，轮式摊铺机牵引性能得到明显改善。最后，通过摊铺机样机的现场试验进一步验证了轮式摊铺机采用全轮驱动系统，使之驱动性能得以明显改善的可行性和方案设计的合理性。文章论述清晰，有大量的理论基础和验证数据作支撑，对同类型的工程机械的开发或提升具有较好的借鉴价值。
[Abstract]:Aiming at the defect of insufficient traction of rear wheel drive wheel paver, through analyzing different drive schemes of wheel paver, it is determined to add front wheel drive system on the basis of rear wheel drive. The scheme of full wheel drive hydraulic system is studied. This paper mainly describes the following aspects of the work: 1. The structure principle and operation process of wheeled paver are deeply analyzed by means of theoretical analysis, computer simulation and test. 2. Through the comparative study of several different front wheel drive systems, it is determined that the remote constant pressure control variable pump system is used as the front wheel drive hydraulic system. 3. Designed and calculated the driving hydraulic system of the full wheel drive paver, and finished the selection of main parts. 4. The simulation model of driving system of full-wheel drive paver is established, and the traction performance, starting acceleration process, starting process of push-load car and so on of wheel-type paver are simulated. The simulation results show that the traction performance of wheeled paver is improved obviously with the increase of front wheel drive hydraulic system. Finally, the feasibility of using the full wheel drive system to improve the driving performance and the rationality of the scheme design are further verified by the field test of the paver prototype. The paper discusses clearly, has a large number of theoretical basis and verification data as the support, and has a good reference value for the development or promotion of the same type of construction machinery.
