What is the difference between full trailer and semi trailer?
There are many kinds of trailers, and their basic frame, body and walking system are basically the same as those of freight cars. The bar plate generally made of thin steel plate, stamping concave edge plate longitudinal carriage fence, welded with transverse ribs, used to increase the stiffness of the car, reduce car compartment floor quality; commonly used wood and covered with a thin plate, or the bottom frame structure composite; usually used 16Mn steel plate molding material welding or by a willow. The longitudinal beam of the frame, the slot type interface structure, two longitudinal beams after width arrangement, the frame has good bending performance.
The upper wing of the straight beam frame is straight. The utility model has the advantages that the bottom of the goods platform of the trailer is smooth, the manufacturing process is simple, the clearance of the ground is generally higher, and the longitudinal passing property is good. Heavy plate type full trailer in order to meet its structure and application requirements. The frame is mainly composed of main beam, crossbeam, support beam and side beam. The load of the whole vehicle passes through the support beam, the suspension, the wheel axle and the wheel of the beam to the ground. The main beam, the supporting beam and the side beam of the frame are welded parts of the box section, and have greater torsional rigidity. The beam connecting the main beam extends to both sides, which is a variable cross section welded structure with higher transverse bending strength. The height of the main frame of the frame is larger and extends downward, so that the longitudinal bending strength of the frame is improved without increasing the height of the platform. A turntable mechanism for balancing suspension is arranged under each supporting beam, so as to realize the whole wheel steering. ?Heavy trailers are heavy in quality and large in size. Generally speaking, the strength of the frame should be increased, and the height of the frame can be lowered as much as possible so that the goods can be loaded and unloaded and transported. The frame of the full trailer frame has a straight through frame, a ladder frame and a concave beam frame.
Different uses of full trailers and semi trailers:Full trailer, that is, after the ordinary car, plus a full hanging car, the two linked between the hooks. Full trailer can increase the loading capacity of trucks, reduce fuel consumption, thereby reducing transportation costs. ?Tank type full trailer - Full Trailer with load area as enclosed tank structure. ?Flat trailer - laden parts of the floor for the whole trailer plate structure and no board. ?Container full trailer - the loading part is a frame structure with no floor, and a full trailer for the purpose of transporting the container. Full trailer dump trailer - truck parts with automatic dump device. Trailer, is composed of a tractor connected behind a semi-trailer compartment, between them through the traction seat supports on the tractor semi-trailer. The most common semi trailers are trailers, large container trucks. Semi-trailer, flat semi-trailer, container semi-trailer, dump semi-trailer, the truck with Trailer parts.
