Direct drive gear systems are used to transmit power to the wheels with an electric motor. They are used on hybrid/electric vehicles as a replacement for the transmission. Steering systems today use direct drive gear with the use of an electric motor. The vehicle’s starter motor can use a direct drive gear. A direct drive gear mechanism is one that takes the power coming from a motor without any reductions. The power is not wasted in drag or friction, such as from a belt or chain. These mechanisms have less moving parts and operate with reduced noise, as well as have a longer lifespan and higher torque value at lower rpm.
