For a front engine front wheel drive (FF) transmission, compactness is one of the main design constraints. In these transmissions, a multiple axis configuration is used to transmit torque from multiple planetary systems to the wheel. Although general characteristics of a simple planetary gear (component) have been studied, no specific investigations are available in literature explaining interactions between planetary systems and torque-transmitting parallel axis gears (full unit or sub-system). This is because analytical calculations of planetary components are already complex and using conventional finite element analysis (FEA) is impossible because it requires a micron size mesh to analyze gear contact correctly. In this paper, a sub-system FEA model (Using Transmission3D FEA Code by AnSOL) of a Ravigneaux and a counter gear pair is introduced. The influences of a parallel axis counter gear on pinions loads are explored by investigation in gear root stress pattern changes. A gap between theoretical load distribution and actual pinion loads are introduced. Additionally, influence of system deflection from stiffness of planetary support on pinion load is investigated. By a series of strain gauge tests under a controlled test jig, reliability of the FEA model is verified for both component and sub-system. Finally, benefits of system-level FEA in the early design stage are explained by introducing effective counter measures with robustness analysis.
