Abstract
The paper considers a task on a search for new methods aimed at development of patentability-based technical solutions of mounting electric traction motors to bogie frame by creating classifications. In result of the analysis, the authors propose a classification that allows systematizing designs of suspensions of all existing traction drives and axial gearboxes and allows determining possible search areas of new technical solutions. On the basis of the classification the authors have proposed designs of mounting electric traction motors to bogie frame, particularly, in conditions of limited vertical dimensions, suspensions of axial gearbox that provide the alignment of electric traction motor and the axial gearbox, and also new designs of connecting links.
