Planetary gear report: ICE on the sun-gear

For a study on the electric hybridization of heavy off-highway trucks, the combination of two electric machines (MG: motor-generator units) with an internal combustion engine (ICE) is considered.
Starting from the knowledge of which characteristic maximum torque-speed load is desired - or is to be expected - at the output member of the planetary gear, i.e. the planetary carrier arm, an overview of some design configurations and possibilities can be studied regarding this load. In this report, the configuration of an ICE on the planetary gear's sun wheel, while the two MG's are located on the ring gear and planetary carrier is studied with as a result the implications on torque, speed and gear sizes of the setup.
The report served as an internal basic report for a commissioned report by an external industry partner.
