Many old drivers believe that they are very familiar with the semi -trailer and the trailer. However, for some newly-introduced whites, it may be that the semi-trailer is indistinguishable from the trailer. Tell us about the relationship between the two today, so that it will be convenient for you to operate later! On the map you guess what car? Let us first say the definition of the lower semi-trailer: the axle is placed behind the center of gravity of the vehicle and is equipped with a trailer that can transmit horizontal or vertical forces to the coupling device of the tractor. Of course, the market is also divided into three types of semi-trailers The first is a passenger semi-trailer: a semi-trailer designed to carry passengers and their carry-on baggage on the design and technical features. This semi-trailer can be equipped according to the relevant regulations. The second type is a general truck semi-trailer: a semi-trailer that carries cargo within an open (planar) or enclosed (bay) cargo space. The third type is a dedicated semi-trailer: Its design and technical characteristics are used as follows: - Special arrangements are required to carry people and/or goods; - Only certain prescribed transportation tasks are performed. For example: log semi-trailer, fire semi-trailer, low-floor semi-trailer, air compressor semi-trailer and so on. It may be that the parents think that this is too official. It is not easy to understand. Then I would say a popular point, semi-trailer is the need to provide a support point for the locomotive, the locomotive is responsible for providing half of the trailer load in addition to power. That is to say, a part of the semi-hung part of its own weight must bear on the tractor, and if it wants to stand up half-hung, it must rely on the front leg. Then the semi-trailer, like the one on the map, belongs to the truck semi-trailer! What about this? Of course, the whole trailer. The trailer, which refers to an ordinary car plus a trailer car, is linked by a hook. An unpowered road vehicle whose design and technical characteristics are required to be hauled by the automobile to be used normally, is mainly used for special purposes such as carrying people or cargo. The locomotive does not need to bear the trailer load, but only provides power to help the trailer overcome the road frictional resistance. In the long-distance transportation, it is common to hang a carriage (or more than one) behind the truck, that is, a trailer. The trailer can also be divided into a variety of styles: Tank trailers - trailers with enclosed cargo tanks. Flat trailer - The floor of the cargo area is a flat-structured, full-trailer trailer. Container trailers - trailers with a frame structure and no floor for the loading of cargo. Self-unloading trailers - trailers with automatic dumpers at the loading area. One of the main characteristics of the trailer is to increase the loading capacity of the truck and reduce fuel consumption, thereby reducing transportation costs! Look at Xiao Bian to say this, is not it feels very good to distinguish between semi-trailer and trailer ! These two types of vehicles are generally used for long-distance transportation.
