What are Drivetrains?

The drivetrain connects the engine that produces the power to the steering wheel that controls the power to rotate the wheel axles. This connection is a physical link between the two components. Depending on the design of the vehicle, these components can be on opposite ends and so require a long propeller shaft.

The operating speed of both the vehicle’s engine and the wheels are usually different and therefore must be matched by the correct gear ratio. For example, as the vehicle speed increases or decreases, the ideal engine speed must remain approximately constant for efficient operations and therefore the gearbox ratio must also remain constant for maximum efficient operations to occur.  For this to happen, the gearbox ratio may be either manually or automatically changed, depending on the style of drivetrain.

There are several major parts of the drivetrain which are the transmission, differential, axels, and drive shaft. The transmission and differential are what are known as ‘boxes of gears”. These provide the mechanical advantage and a change in the direction of kinetic energy to move the vehicle. The transmission is the first part to receive the kinetic energy from the crankshaft of the engine. It uses different gears to provide mechanical advantage for when the driver wants the vehicle to speed up or slow down.  The driver changes dears to access this mechanical advantage for control.

Types of Drivetrains

Front-wheel drive: This is the most common type of drivetrain. It is when the engine power flows to the front wheel so the driver can control the vehicle.

Rear-wheel drive: While not as common, the engine power flows to the two rear wheels to drive the vehicle. Heavy trucks usually require rear-wheel to distribute heavy loads. The transmission may be directly behind the engine or combine with the rear axle.

Four-wheel drive: The vehicle’s power flows to all four wheels for maximum control and versatility. Usually a transfer case splits the power from front to the rear. This type of drivetrain is perfect for off-roading and other all-terrain activities.

Signs of A Failing Drivetrain

If you see any visible signs of damage or fluid leak from the drivetrain or adjacent parts, immediately visit an automotive mechanic immediately for repair.

Another thing you should watch out for is any vibrations or shuddering while driving. You should be careful when on the highway, driving at high speeds, or accelerating. Lastly, you may encounter a strong burning oil smell which can also indicate there is something wrong with the drivetrain.
