COMPOSITE METAL FLEXPLATE

Номер: US20200016688A1
Автор: Cremonesi James D., Li Huaxin, Wang Qigui, Wilson Daniel J., Yang Jianghuai
Принадлежит:

A composite metal flexplate is disclosed that includes an aluminum center plate and a steel ring gear joined to the aluminum center plate by a solid-state joint. The solid-state joint that joins together the aluminum center plate and the steel ring gear may be formed by friction welding. During the friction welding process, a surface of an annular body of the steel ring gear is preheated, followed by bringing the preheated surface of the annular body into contact with a surface of a periphery of a circular body of the aluminum center plate. The two contacting surfaces are then caused to experience relative rotational contacting movement, which generates frictional heat therebetween and softens adjacent regions of the steel ring gear and the aluminum center plate. Once this occurs, an applied force is administered to compress and forge the contacting surfaces together, thereby establishing the solid-state joint. 1. A composite metal flexplate comprising:an aluminum center plate having a circular body that defines a central opening about an axis of rotation of the composite metal flexplate, the circular body having a periphery; anda steel ring gear that includes an annular body and external gear teeth that are integral with and circumferentially disposed about the annular body, the annular body of the steel ring gear being affixed to the periphery of the circular body of the aluminum center plate by a solid-state joint.2.
