Why do big trucks have ten wheels?

1. Large trucks are used to carry heavier goods, and the larger the truck, the heavier the goods carried, so more wheels should be used to share these weights. Everyone must have had the experience that it is easier to carry something with two hands than with one. So the more wheels you have, the easier it is, and the smoother and safer it will be.

In addition, it can also reduce the damage to the truck itself and protect the road surface.

2. Large truck transportation can achieve door-to-door cargo transportation, which is much more convenient than railway transportation. Its disadvantage is that the speed is slower and the noise is louder. Trucks mostly use diesel engines. **Less expensive diesel, the emitted fumes cause air pollution.

Not all big trucks have 10 wheels. The 10 wheels you are talking about are 6*4 tractors or 6*4 dump trucks and trucks, usually there are two guide wheels in the front and two axles in the back are drive wheels (there is a rear axle with a lift bridge that is not driven).

Because the big truck has to drag a lot of goods, the goods are very heavy, so it is necessary to use ten wheels, some more than ten wheels, depending on how big their existence is, the larger the carrying capacity, the more wheels are needed, so as to reduce the pressure on the ground, otherwise the ground will be crushed.

Because the load of large trucks is relatively heavy, it is said that he needs more wheels to bear the load, but it does not mean that all large trucks are four wheels, as long as the load of the large truck is what is the load, there are more large trucks with more wheels, some reach more than 20, and 30 are available.

The large trucks are all tons of goods, so they are ten wheels, so the vehicles will be more stable.

1 ton-7 tons are generally 4-6.

8 tons-25 tons, generally 12, the first 4, the last 8

112 axles 1 = 2 wheels 1 = 4 wheels (drive wheels) 2 = 8 wheels A total of 14 wheels.

25 tons-31 tons, 14 pcs, front 4, rear 10

122 axles 1 = 2 wheels 2 = 8 wheels (drive wheels) 2 = 8 wheels A total of 18 wheels.

It's hard to say more than 31 tons, 123 axles 1 = 2 wheels 2 = 8 wheels (drive wheels) 3 = 12 wheels A total of 22 wheels.
