Recently, trailers and center axle trailers have been discussed a lot, so many people will ask what is the difference between the trailer and the center axis.
Xiao Bian first talk about the whole trailer, what is a full trailer, the trailer's load is borne entirely by itself, and the locomotive is only linked by a hook. The locomotive only provides power to help the trailer overcome road frictional resistance. The hanging can stand on its own tire. The trailer, which refers to an ordinary car plus a trailer car, is linked by a hook. The trailer can increase the load of trucks and reduce fuel consumption, thereby reducing transportation costs. So what is a semi-trailer? The semi-trailer is a trailer that is positioned behind the center of gravity of the vehicle (when the vehicle is uniformly loaded) and is equipped with a coupling device that can transmit horizontal or vertical forces to the tractor.
The difference between a trailer and a semi-trailer is that since the axles of the semi-trailer are all at the rear of the vehicle, there is no doubt that the counterweight of the semi-trailer is between the trailer axle and the rear axle of the tractor. In this way, the weight of the goods is borne by the two axles. If the rear of the semi-trailer is lengthened, and the goods are placed in the extended part, the front of the trailer will be tilted like a seesaw. This will reduce the weight of the tractor part. This is somewhat similar to the working mode of the center axle trailer.
The advantage of the central axis is that it is stable and the times are constantly evolving. Now that the center axle has been allowed to transport cars, isn't the next step to fully release the central axis of the truck? If the truck is allowed to be towed on the central axle trailer, it should be advantageous for freight transportation on the expressway. The coaches are familiar with the car carrier card, along with the encouragement of the new version of GB1589 on the center axle car, and the implementation of the double-row single-row loading program from September 21st. Against this background, the domestic The caravan market is undergoing an unprecedented transformation.
Of course, there are disadvantages in the central axis, especially when the downhill risk, after all, the center of gravity is too close to the front, so the balance should be grasped well, this can play the biggest advantage of the central axis.
