Principles of Truck Operation

When we start the car, the engine generates power and transmits the power to the gearbox. The power passes through the gears in the gearbox to convert the high-speed and small-torque power into low-speed and high-torque power, and then transmits it to the drive rear axle through the drive shaft. The driving rear axle drives the driving rear wheels to rotate, so a car starts to move.
