A compound planetary gearset functions like two planetary gearsets put together. Understand compound planetary gearsets and an automatic transmissions construction.
This amazing piece of gearing has appeared on HowStuffWorks in advance of. You might identify it from the electrical screwdriver posting. An automatic transmission has two full planetary gearsets folded alongside one another into one particular component. See How Gear Ratios Get the job done for an introduction to planetary gearsets.
A gearbox includes gears of varying sizes, because of the unique calls for in periods with the torque essential within the wheels dependent upon the street, load, and terrain, as an example; climbing cars require larger torque than driving on a straight street.
