Chapter 16 Vehicle automatic transmission The structure of fluid coupling There is no mechanical connection between the impeller and the turbine , which are called as running wheel 工作 轮and rely on the flowing fluid to transmit the power. There are many vanes arranged along the radial direction of the annular shell composed by the running wheel. The working fluid is stored in the annular shell. After assembled, there is a certain gap (3~4mm) between the impeller and the turbine, the longitudinal section through the axis is annular, which is called as circular circle环形环
