ABSTRACT: The improve of transmission system’ performance means the increase of motor vehicle’s motivation and economical, the improve of the reliability of vehicle transmission system will benefite to the improvement of vehicle’s safety, focus on the development of vehicle transmission inertia flywheel must be a promising project.

     The detection of automobile transmission performance is one of the most important project for motor mobility, economic and security detection, detect vehicle transmission performance object will promote the development of motor vehicle .This paper focuses on the inertia flywheel one of the most important part of vehicle transmission inertia flywheel test platform and make a series of discuss and study. Then, this paper have analyzed the working principle of the inertia flywheel in detail, aiming at the possible problems in the actual work, this paper have a necessary discuss and try to make it out, it also make a necessary explain for the select of the components ,besides, this paper have some improvement for some important parts of the device.

Keywords: vehicle transmission; inertia flywheel; coarse regulation group; accurate regulation group; check the strength

     目前来说，对汽车传动性能的检测一般通过实车路测，不仅费时，成本较高，而且准确度不高，此外其操作存在一定风险。本课题所作惯性飞轮通过组装后，不仅可以对不同型号的机动车辆传动性能进行模拟研究，而且可以减小环境对实验结果的影响。其更加符合实际情况。自动化程度高，更容易实现自动化的要求。相对于路测来说，滚筒式制装置有许多突出优点，首先，该方法检测过程简单，所耗时间较短。其次，占地面积小，相对于实车路测来讲，该方法可在室内进行操作，故可以避免风向，路面情况等一系列天气原因的影响。此外，设备耗资低，大多数零件可在市场实行产业化生产。
