First Equipment In initial equipment, the more compact sun gear is driven clockwise because of the turbine during the torque converter. The planet copyright tries to spin counterclockwise, but is held still through the a person-way clutch (which only enables rotation while in the clockwise way) and the ring gear turns the output. The little gear has thirty teeth and also the ring equipment has seventy two, And so the equipment ratio is:

Employing this information and an advanced Regulate approach based on fuzzy logic -- a technique of programming Handle devices employing human-type reasoning -- electronically controlled transmissions can do such things as:
Depending on the motor vehicle, gearboxes can be found in manual or automatic sorts. Both equally utilise intricate gear methods but operate in another way On the subject of driver enter.
