On the truck, we often see some parameters like "4x2, 6x2 ...". Although some people may know that these parameters represent the driving mode of the vehicle, it is still unclear how to interpret them. Therefore, it is necessary to popularize for everyone what is a 6x4 driver and what is a 4x2 driver. After a detailed understanding of the advantages and disadvantages of different drive forms, it can also help everyone have a more wise choice when buying a truck.


What does "4x2, 6x2 ..." stand for?

4x2, 6x2, 6x4, 8x4, these "multiply by several" combinations are not random barking, the front numbers and the following numbers have specific meanings. The number before the "x" number indicates the number of tires (groups), and the number after the "x" number indicates the number of drive wheels (groups). For example, a 4x2 model means that the car has 4 sets of wheels, of which 2 sets of wheels have driving force; a 6x4 model means that the car has 6 sets of wheels and 4 sets of wheels have driving force. Do not reverse the two numbers before and after to make the strange statement of 4x6, 2x4.

It should be noted that truck drive shafts are generally designed with twin tires installed, that is, two tires are mounted on each side of the drive shaft. How should this be calculated? As long as two tires are installed side by side, it is counted as one tire group. For example, the 6x4 model has a total of 10 tires, 2 steering shafts, and 8 drive shafts. Each 2 is installed together. We can only count 4 sets of tires. Otherwise, the 6x4 model will become 6x8.

Powerful off-road vehicles are generally all-wheel drive. You should also see some cars marked "4x4" in life. Trucks also have all-wheel drive 6x6, 8x8 and other drive forms for some special vehicles. In most cases, the greater the number of driving wheels, the stronger the driving force of the vehicle and the better the adaptability to road conditions.
