Q: Why do some cars have Direct Drive Gear?

asked by on

What is direct drive gear?

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.
