Power Flow Schematic: Notes
WARNING: This page does not describe the selected car, but rather 212 other vehicles, including the 2012 BMW 750i, 2012 BMW 750Li, 2011 BMW M3, 2011 BMW 750i, and 2011 BMW 750Li. However, it is still accessible from the selected car via links, so may be relevant.
In order to understand power flow schematics, a relationship must be drawn between the actual components and the schematic representation. This example uses the 4HP22/24 power flow schematic. The 4HP22/24 transmission uses a Simpson Planetary Gearset and an auxiliary gearset. The auxiliary gear set is a simple planetary gearset. See Fig 1.
