If the car train with a total length of 32 meters and can carry more than 70 tons of goods is introduced into China, can it further improve the construction of efficient land transport logistics network and promote the freight industry to move towards a more energy efficient and efficient direction?Do you remember the modular car train that Scania exhibited in Qingdao some time ago? Simply put, this double-trailer train mode can be simply understood as a tractor, a full trailer and a half trailer three parts, in which the full trailer is set up with a standard traction saddle.

The dual-trailer focuses on high efficiency and energy saving, and has advantages in optimizing road transportation, improving transportation efficiency and economy, and promoting high efficiency and low carbon. However, because the double-trailer exceeds the provisions of GB1589 that "the maximum allowable total mass of the vehicle is 49t, the maximum total length does not exceed 16.5m, and the total length of the car train does not exceed 22m", it is an overlong and overweight vehicle, so it has not been legally operated on the road.

Recently, many places across the country have gradually turned on the summer "barbecue" mode. Under the hot sun, the temperature of the road surface is significantly higher than the air temperature. The tires are affected by thermal expansion and contraction, the tire wall becomes thinner, the heat dissipation efficiency becomes worse, and the probability of tire blowout is higher Higher in other seasons. Once a tire blowout accident occurs, it will cause the vehicle to deflect or tilt instantly, and it is easy to lose control.
