What does the 6x4 drive configuration mean?

[OAlex]

Drive configuration 6x4 indicates that the vehicle has six wheels, with four of them being drive wheels. The drive configuration of trucks is typically represented by the total number of wheels multiplied by the number of drive wheels. The number before 'x' represents the number of tire (groups), and the number after 'x' represents the number of drive wheel (groups). Below is a related introduction: Introduction to the 6x4 drive configuration: 6x4: A common arrangement for many heavy-duty trucks. One front axle is a steering support axle, and two rear axles are drive axles. An axle, also known as a shaft, is connected to the frame or load-bearing body via suspension, with wheels installed at both ends. Its function is to transmit forces and moments between the frame or load-bearing body and the wheels in all directions. The control device of the traction control system is a computer that monitors the speed of all four wheels and the steering angle of the steering wheel. When the vehicle accelerates, if the computer detects a significant speed difference between the drive wheels and non-drive wheels, it immediately determines excessive driving force and sends a signal to reduce the engine's fuel supply, thereby lowering the driving force and reducing the slip rate of the drive wheels. Advantages of the 6x4 drive configuration: The advantage of the 6x4 drive configuration is having four drive wheels, which provides stronger driving force and better road adaptability, especially on slippery surfaces like winter snow and rain, enhancing vehicle stability and reducing the risk of skidding or loss of control. The downside is that on roads with good conditions, tire wear and fuel consumption are relatively higher. The drive axles are also heavier and more complex in structure compared to load-bearing axles, resulting in a higher vehicle weight and purchase cost.
