Final Conventionally Designed Gearbox

edit

With planetary gearboxes, the number of gears can be increased conventionally by adding additional gearsets as well as brakes and clutches, or conceptually by switching from serial to parallel power flow. The conceptual way requires a computer-aided design.

The 5HP is the last transmission family with serial power flow: to provide more gears, components were added. This makes these transmissions larger, heavier and even more expensive to manufacture. As the presence of 10 main components (together with brakes and clutches) in the Ravigneaux gearbox types shows, this meant the end of the conventional gearbox design. The approach of the all new Lepelletier gear mechanism from the later 6HP-family, requiring only 8 main components for 6 gears, reflects the progress that this new paradigm represented.
