Dual-purpose trailer for highways and railways

Abstract

The invention relates to the field of automotive vehicles, in particular to a dual-purpose trailer for highways and railways. The trailer comprises a carriage utilizing a train skin body as a trailer body, and automobile wheels arranged at the bottom of the train skin body and is characterized in that the carriage utilizes the train skin as the trailer body; the bottom of the dual-purpose trailer for the highways and the railways provided by the invention is provided with automobile wheels and train wheels, so that the trailer can run on a rail and the friction factor between the train wheels and the rail is smaller, and therefore by utilizing the dual-purpose trailer for the highways and the railways provided by the invention, the transportation cost is low and the transportation time is shorter; and the bottom of the dual-purpose trailer for the highways and the railways provided by the invention is provided with the automobile wheels, so that after arriving at the station, the dual-purpose trailer for the highways and the railways is directly used as road transportation till arriving at the destination, and the procedure of transfer of cargoes is omitted, i.e., the transfer time is reduced, the loading and unloading expenses for transfer are omitted, and the transportation cost is further lowered.

Description

technical field [0001] The invention relates to the field of motor vehicles, and more specifically relates to a dual-purpose trailer for road and rail. Background technique [0002] At present, railway transportation is in the backbone position in my country's transportation industry. It has the advantages of fast transportation speed, large transportation capacity, low transportation cost, and relatively safe and reliable. However, the total operating mileage of my country's railways is still in short supply. There is still a large gap in the coverage of the structure to the country, especially in the Inner Mongolia railway section, which often leads to the fact that the goods transported by railway cannot directly reach the destination. Usually, the goods are loaded on the car after arriving at the railway station. Deliver goods to their destinations by road transport. The above-mentioned method of combined transportation by rail transportation and road transportation must ...

Problems solved by technology

[0003] In addition, road transportation is more flexible and covers a wider area, and it is also in a more important position in my country's transportation industry. The use of road transportation can avoid the link of transferring goods, but the common vehicles for transporting goods are some heavy trucks, such as grain trucks , oil tank trucks, coal trucks, dump trucks, and trailers. These vehicles are heavy, and driving on a certain section of road for a long time is a burden on the road, causing frequent damage to the road, and road congestion every time the road is repaired. It is not conducive to road traffic and road construction, and the friction coefficient between the car wheel and the ground is much greater than that between the train wheel and the rail, so the transportation cost of road transportation is high
