Summary
The increasing complexity of powertrains and the increasing variants of vehicles are changing the world for transmissions: First of all, the complexity of the transmission itself has been growing since the transmission, as the heart of powertrain hybridization, must fulfill more functions than just converting torque and speed. Automation of transmissions is becoming standard, and the electric machine is typically integrated in the transmission today. Secondly, the number of transmission variants is steadily increasing. After years of only manual transmissions and automatic transmissions with planetary gear sets and torque converter, there are many more variants available today, for example double clutch transmissions, planetary automatic transmissions with launch clutches, CVTs and eCVTs. Finally, these transmissions have to fit in a wide variety of powertrains with many different power sources including their variants as well as many body forms and variants.
