Full trailer turntable pallet trailer large tractor semi-trailer transport vehicle price/picture/manufacturer

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.

　　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. A semi-trailer is composed of a tractor connected to a semi-trailer compartment behind it, and they are supported on the tractor by the semi-trailer's towing seat.

The angular transmission ratio of the full axle steering device is 1, and the transmission ratio of the wheel steering device is generally greater than 1. This is a schematic diagram of the structure of the wheel steering device. From the figure, it can be seen that the steering device is actually composed of two parts: one is the conventional car front wheel ladder structure, and the other is two sets of four-bar linkage mechanisms that transmit the left and right rotation of the traction rod to the left steering arm to produce left and right deflection. The function of the steering trapezoid is to ensure that when the trailer turns, both the left and right steering wheels can make an instantaneous turn and perform pure rolling without sliding on different circles. The optimization design calculation of this part of the organization is relatively mature. 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 of Ruixin Trailer Factory 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.
