CIMC sidewall drawbar trailer whose total weight is borne by itself is called a full trailer, and usually a full trailer is also referred to as a trailer. It is a kind of unpowered road vehicle that has no power, independent load, and relies on other vehicles to tow. It is a kind of unpowered road vehicle that needs to be towed by the drawbar trailer due to its design and technical characteristics. It is used to carry people or goods.

Types of trailers

sidewall drawbar trailers or dropside semi-trailers do not have their own power unit, and the automobile trains composed of them and towing vehicles belong to the category of automobiles. A sidewall semi trailer is a trailer whose axle is placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded) and is equipped with a coupling device that can transmit horizontal or vertical forces to the tractor. That is, part of the total weight of the trailer is borne by the tractor. Its characteristics: it has no power, and it is shared with the main vehicle, and the vehicle is driven by the main vehicle.

Dropsdie Semi trailer

A trailer whose axle is placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded) and is equipped with a coupling device that can transmit horizontal or vertical forces to the tractor.

Sidewall semi trailer refers to a vehicle that has no power and is driven by the main vehicle. The length of the semi-trailer shall not exceed 17 meters, except for the semi-trailer that transports automobiles.

Trailers with (steerable) front wheels are called full trailers, and those without front wheels, and the trailer with the trailer on the front of the trailer is called semi-trailer.

Sidewall Drawbar trailer

A tow bar trailer is a trailer with at least two axles. It has: one axle can be steered; it is connected to the tow vehicle through an angularly movable tow bar; the tow bar can move vertically and is connected to the chassis, so it cannot bear any vertical force. Semi-trailers with hidden support frames are also used as tow bar trailers.

The difference between semi-trailer and full trailer

There are many types of trailers, and the basic frame, body, and running system are basically the same as those of trucks. Railcars are generally made of thin steel plates, and longitudinal concave ribs are stamped out on the rails of the carriage, and ribs are welded transversely to increase the rigidity of the carriage and reduce the quality of the carriage; the floor of the carriage is generally made of wood and covered with thin steel , Or use iron-wood mixed structure floor; the frame is usually made of 16mn steel plate, pressed into profiles, welded or welded. The longitudinal and transverse beams of the frame mostly adopt a grooved interface structure, and the two longitudinal beams are arranged at the front and rear with equal width, so that the frame has better bending resistance.

A full trailer is generally composed of a frame, a body, a traction device, a steering device, a suspension, a traveling system, a braking system, and a signal system.

The upper wing surfaces of the straight beam frame rails are all straight. The advantage is that the bottom of the trailer cargo platform is flat, the manufacturing process is simple, the ground clearance is generally high, and the longitudinal passability is good. In order to meet the requirements of its structure and use, the heavy-duty flat trailer. The frame is mainly composed of main beam, cross beam, supporting beam and side beam. The load of the vehicle is transmitted to the ground through the support beams, suspension, wheel axles and wheels between the beams. The main beam, supporting beam and side beam of the frame are welded parts with a box-shaped section, which have a large torsional rigidity. The beam connecting the main beam extends to both sides and is a variable cross-section I-shaped welded structure with high transverse bending strength. The height of the main beam of the frame is large and extends downwards, so that the frame's longitudinal bending strength is improved without increasing the height of the cargo platform. A turntable mechanism for installing balance suspensions is provided under each supporting beam to realize all-wheel steering.

Heavy-duty trailers carry high quality goods and large dimensions. Generally speaking, the strength of the frame should be increased and the height of the frame should be reduced as much as possible to facilitate the loading and unloading and transportation of the goods. According to the structure of the longitudinal beam, the full trailer frame includes a straight-through frame, a stepped frame and a concave beam frame.
