Equipment is employed to transport electric power from a single shaft to a different. The quantity of torque transported via gears will depend on the amount of enamel and measurement from the equipment.
The center of focus would be the planetary gearset. About the size of the cantaloupe, this one particular part generates all of different gear ratios that the transmission can generate. Every thing else during the transmission is there that will help the planetary gearset do its point.
Automatic gearboxes can sap extra electric power with extra fluid couplings but are commonly headache-totally free.
