【摘要】：DCT双离合器自动变速器凭借着换挡的平顺性及燃油的经济性,正逐渐成为变速器行业的新宠。在对双离合器自动变速器的自主研发中,其装配工艺的研发也是必不可少的一个环节。压装工艺作为变速器装配中重要的工艺过程,直接关系到变速器的装配质量,进而影响到变速器整体的性能。 本文首先介绍了变速器压装工艺的国内外现状,阐述了DCT双离合器自动变速器的结构特点、工作原理及系统组成。 然后,针对DCT自动变速器中离合器壳体轴承外圈的压装过程,阐述了过盈压装力学理论解析及有限元分析理论基础,为过盈压装工艺的有限元仿真提供理论指导。 根据理论分析,对变速器壳体轴承外圈压装工艺进行了有限元仿真,得出压装力-位移曲线并对压装过程中零件的应力、应变情况进行分析。通过仿真分析,研究了不同压装工艺参数对压装力-位移曲线的影响,为变速器壳体轴承外圈压装工艺的优化、压装设备的设计提供参考依据。 最后,进行了电动伺服压装试验。通过试验结果与仿真结果的对比,验证了变速器壳体轴承外圈压装有限元仿真分析的可行性,并对比出不同压装参数对压装力的影响程度,为压装力-位移曲线的监测及产品的设计提供借鉴。
[Abstract]:DCT dual clutch automatic transmission is becoming a new favorite of transmission industry with its smoothness and fuel economy. In the independent research and development of dual clutch automatic transmission, the development of its assembly process is also an essential link. As an important process in the assembly of transmission, the pressing process is directly related to the assembly quality of transmission, and then affects the whole performance of transmission. In this paper, the present situation of pressure mounting technology of transmission is introduced, and the structure characteristics, working principle and system composition of DCT double clutch automatic transmission are expounded. Then, in view of the pressing process of clutch shell bearing outer ring in DCT automatic transmission, the theoretical analysis of interference press mechanics and finite element analysis theory are expounded, which provides theoretical guidance for the finite element simulation of interference press technology. According to the theoretical analysis, the finite element simulation was carried out on the pressing process of the outer ring of the transmission shell bearing, and the pressure-displacement curve was obtained, and the stress and strain of the parts during the pressing process were analyzed. Through the simulation analysis, the influence of different pressing process parameters on the pressure-displacement curve is studied, which provides a reference for the optimization of the pressing process of the outer ring of the bearing of the transmission shell and the design of the pressing equipment. Finally, the electric servo pressure mounting test is carried out. By comparing the test results with the simulation results, the feasibility of the finite element simulation analysis of the outer ring of the transmission housing bearing is verified, and the influence of different pressing parameters on the pressure loading force is compared. It provides reference for the monitoring of pressure-displacement curve and the design of products.
