Abstract
A planetary carrier subassembly for a transmission is provided that is sintered using braze preforms. The carrier subassembly may include a powder metal carrier member having a plurality of carrier legs extending a distance therefrom, and a powder metal cover member having a plurality of cover legs extending a distance therefrom. The carrier member and cover member are positioned such that respective ends of the carrier legs and ends of the cover legs are aligned with one another. The subassembly is provided with at least one braze preform including a braze material and a sacrificial binder, such as a wax. The braze preform is placed between a respective pair of the aligned carrier legs and the cover legs. The braze preform is provided with a geometry configured to direct a flow of braze material during a subsequent sintering process.
