Abstract: A torque converter has an end cover or input shell which is stamped from a sheet metal plate and has a stiffening fluid portion and an outer flow formed annular rim. The impeller, turbine and stator are assembled along with a torque converter clutch after which the rim portion of the end cover is welded to the impeller. The impeller and the cover have a flange or radially extending portion that is selectively trimmed to control the dynamic balance of the assembly. The turbine member is cast with the outer core and blade portions integral and an inner core member is welded thereto. This is completed prior to assembly within the torque converter.

Abstract translation: 变矩器具有端盖或输入外壳，该端盖或输入外壳由金属板冲压并具有加强流体部分和外流形成的环形边缘。 叶轮，涡轮和定子与变矩器离合器一起组装，之后端盖的边缘部分焊接到叶轮上。 叶轮和盖具有凸缘或径向延伸部分，其被选择性地修剪以控制组件的动态平衡。 涡轮机构件被铸造成具有一体的外芯和刀片部分，并且内芯件被焊接到其上。 这是在变矩器内组装之前完成的。
