5-meter flatbed truck, 6-meter full trailer, 2-meter 55 wide full trailer model

Description :

　　The overall arrangement of the full trailer wheel steering device is that the function of the full trailer steering transmission mechanism is to convert the left and right swing of the traction arm (shaft rod) around the traction pin into the rotation of the steering wheel around the main pin, thereby achieving full trailer steering. Due to the limitations of the chassis, the turning angle of the steering wheel cannot be too large. However, in order to reduce the turning radius of the car train, the traction arm hopes to make a significant rotation when towing the trailer to turn. Therefore, it is necessary to determine a suitable transmission ratio for the steering mechanism. Increasing the angle transmission ratio of the steering mechanism is beneficial for reducing the small turning diameter of the fully trailer train and improving the maneuverability of the car train; However, increasing the transmission ratio will increase the lateral force experienced by the trailer when turning, which increases the possibility of the trailer slipping and deteriorates the stability of the car train operation.

　　There are many types of full trailers, and their basic frame, body, and walking system are basically the same as those of trucks. Railgar cars are generally made of thin steel plates, with longitudinal concave edge plates stamped on the car railings and transverse convex ribs welded to increase the rigidity of the car and reduce its mass; The bottom plate of the carriage is generally made of wooden boards and covered with thin steel plates, or a mixed structure bottom plate of iron and wood is used; The frame is usually made of 16Mn steel plate, which is pressed and formed by welding or splicing. The longitudinal and transverse beams of the frame often adopt a groove type interface structure, and the two longitudinal beams are arranged with equal width in front and back, which makes the frame have good bending resistance. A full trailer generally consists of a frame, body, traction device, steering device, suspension, walking system, braking system, signal system, etc.

　　The upper wing surface of the longitudinal beam of the straight beam frame is straight. Its advantages lie in the flat bottom plate of the trailer cargo platform, simple manufacturing process, generally high ground clearance, and good longitudinal passability. Heavy duty flatbed trailers are designed to meet their structural and operational requirements. The frame is mainly composed of main beams, cross beams, support beams, and side beams. The load of the entire vehicle is transmitted to the ground through the support beams between the crossbeams, suspension, wheel axles, and wheels. The main beam, support beam, and side beam of the frame are welded components with box sections, which have high torsional stiffness. The crossbeam connecting the main beam extends to both sides and is a variable cross-section I-shaped welded structure with high lateral bending strength. The height dimension of the main beam of the frame is relatively large and extends downwards, which improves the longitudinal bending strength of the frame without increasing the height of the cargo platform. Under each supporting beam, there is a turntable mechanism installed with a balanced suspension to achieve all wheel steering.

　　The different purposes of full trailer and semi-trailer: Full trailer refers to an ordinary car with a fully trailer attached to the rear, and the two are connected by a hook. Full trailers can increase the loading capacity of trucks, reduce fuel consumption, and thus lower transportation costs. Tank type full trailer - a full trailer with a closed tank structure for cargo loading. Flat trailer - a trailer with a flat structure and no railings on the floor of the cargo area. Container trailer - a fully loaded trailer with a frame structure and no floor, specifically designed for transporting container compartments. Self dumping full trailer - a full trailer with an automatic dumping device in the cargo area.
