Direct drive is a type of transmission that allows for better gear shifting within a motor vehicle. Because fewer gears are connecting, the vehicle cruises better at a higher gear. That’s a fairly simple explanation, so let’s talk a bit more about direct drive gear.

How direct drive works

With direct drive, a shift control works along with the clutches, maintaining an optimum connection. Two input countershafts permit the system to function, and they’re managed directly by a motor within the gearbox that regulates the shifting. The motor keeps the rotation speed consistent and allows smoother shifting so that power can go through the motor, directly to the back wheels.

Implications for the modern driver

Direct drive could conceivably revolutionize modern transportation. In Australia, Evans Electric has introduced a direct drive electric car. It’s the Mitsubishi Lancer Evolution, a direct drive four door sedan. You have to wonder why someone didn’t come up with the idea sooner, since there’s no simpler system than direct drive. To put in perspective just how simple and efficient this system is, think about this – the motor turns the wheels directly. You don’t need a transmission! It’s reliable, and eliminates many of the moving parts that require constant repair and replacement. This makes it energy-efficient and environmentally friendly.

This revolutionary vehicle is also capable of electromagnetic braking. Hydraulic friction brakes are a thing of the past, because braking is achieved using the wheel motors.

Into the future

With the growing popularity of electric cars, direct drive is likely to become more commonplace. This will mean a reduced carbon footprint, fewer vehicle repairs, and better vehicle performance. It’s next generation, and it’s already here.
