摘要
湿式离合器在车辆自动变速器中获得了广泛的应用,其工作特性对自动变速器的工作状况具有重要影响。展开对湿式离合器工作特性的深入研究,对于提高,促进我国自动变速器行业发展具有重要意义。
本文通过对湿式多片离合器结构特点的学习,了解到了湿式多片离合器具有工作性能更稳定、接合更平顺、具有吸收振动、冲击的能力和磨损小,工作寿命长等优点。通过进一步了解国内外针对湿式多片离合器的研究现状,搭建了自己的研究平台。
本文首先分析湿式离合器的工作环境,确定了实验平台的布局结构。选择西门子伺服电动机1LG-283-2AB70作为动力源;加载装置选择洛阳凯迈公司的电涡流测功机CW100。选用瞬态转矩转速传感器ZH07-1000G来输出湿式离合器的接合过程转速、转矩的变化。
其次为达到实际的工作环境,设计了两档的增速箱,可将电动机的转速增加到6600r/min,在此过程中,对增速箱的齿轮和轴进行计算和校核;按照设定的摩擦片尺寸,计算出摩擦片的数量并进行校核;对增速箱油道的设计计算。
最后就是增速箱的机构设计和试验台的结构设计。

Abstract
Wet clutch automatic transmission in a vehicle to get a wide range of applications, the operating characteristics of the automatic transmission has an important impact on the working conditions. Expand the operating characteristics for wet clutch-depth study of research for improving the design level of domestic automatic transmission, automatic transmission industry to promote the development of great significance.
Based on the structural characteristics of wet multi-plate clutch to learn, learned wet multi-plate clutch with a performance more stable, more smooth engagement with the absorption of vibration, shocks and wear, long working life and other advantages. By further understanding of domestic and wet multi-plate clutch for Research, set up their own research platform.
The first is the understanding of the wet clutch work environment to determine the experimental platform layout structure. Select Siemens servo motor 1LG-283-2AB70 as a power source; loading device selection Luoyang CAMA's eddy current dynamometer CW100. Optional transient torque and speed sensor ZH07-1000G to output the wet clutch engagement process speed, torque changes.
Second, in order to achieve the actual work environment, the design of two tranches of the growth rate box, the motor speed can be increased to 6600r/min, in this process, the growth rate of the gear box and shaft calculation and verification; according t
