With the rapid development of economy, semi-trailer and trailer parts has been an indispensable existence in daily production and management. Compared with "monomer" cars, semi-trailer can improve the comprehensive economic benefits of highway transportation. Transportation efficiency can be improved by 30-50%, cost can be reduced by 30-40%, fuel consumption can be reduced by 20-30%. At the same time, different from the full trailer, the semi-trailer is a trailer whose axle is placed behind the center of gravity of the vehicle (when the vehicle is uniformly loaded) and equipped with a connecting device that can transfer horizontal or vertical force to the tractor. Generally, the full trailer has two axes and the semi-trailer has one axle. Semi-trailer refers to a vehicle that has no power of its own and is jointly carried by the main vehicle and driven by the main vehicle.

Briefly, the full trailer is connected to the truck in front by hooks. The semi-trailer is connected with the traction seat of the tractor through the traction pin. The common container transport vehicle is a typical semi-trailer train, and the rear loading part is the semi-trailer.

There are also differences in use. Full trailers are mainly used for short-distance transportation in factories, ports, docks, warehouses and other fields, while semi-trailers are mainly used for long-distance transportation of goods.

We will be the specific classification of semi - trailer dump semi - trailer, grille semi - trailer , trailer landing gear, trailer rims and so on.

Dump type semi-trailer:

A car with an automatic dumping device in its compartment. Also known as dumper and engineering vehicle, it is composed of automobile chassis, hydraulic lifting mechanism, power take-off device and cargo compartment. In civil engineering, it often works together with excavators, loaders, belt conveyors, etc. to form loading, transportation and unloading production lines for loading, unloading and transportation of earthwork, sandstone and loose materials. Since the loading carriage can automatically dump at a certain angle, the unloading time and labor are greatly saved, the transportation cycle is shortened, the production efficiency is improved, the transportation cost is reduced, and the loading volume is marked. It is a common transport machine.

Grid-type semi-trailer:

The van type semi-trailer series products are used for the transportation of household appliances, light textile goods, coal, sandstone and other building materials as well as chart and plate goods. The car body is made of high-strength cold-rolled corrugated steel plate, with no framework structure. The center is everywhere, with multiple choices. The loading space is large, and the box body is reasonably distributed. The X-shaped brace has the characteristics of multi pull, heavy load and light weight. The car top has closed type, push-pull open type, open type, open tarpaulin pole type, etc. it is easy to operate and meets the diversified and personalized requirements of users. The van type transport semi-trailer adopts the closed side guard rail design, which effectively reduces the lateral risk and energy consumption when the vehicle is running at high speed. The rear protection design has reasonable cart accessories to facilitate operation. It is refitted or separately manufactured on the chassis of a van type vehicle, which can be divided into passenger van type and carriage type according to the different carriages. The passenger compartment and cab are generally integral structures, such as ambulances, accommodation vehicles, environmental inspection vehicles, dining cars, TV relay vehicles, etc. The carriage and cab of the carriage type are generally split structures, such as van type less than carload transport vehicles, refrigerated and insulated vehicles, etc. The specific structural form of the carriage varies according to its function. The compartment of the refrigerated and insulated vehicle not only has the function of a general compartment, but also has the function of heat insulation and insulation; The top cover of the convertible top compartment can be vertically lifted and lowered to change the volume of the compartment and meet the loading and unloading requirements of different goods; The wing open carriage facilitates loading and un loading of goods and improves loading and unloading efficiency. The series van is divided into box type Yunshi semi-trailer and type II chassis modified van. The vehicle body is made of high-quality steel, advanced technology and strict production process. 

Today focus on the introduction of plate spring:

The advantages of plate spring are simple structure, reliable work, low cost, convenient maintenance. It is not only the elastic element of the suspension, but also the guiding device of the suspension. It is hinged to the frame at one end, which transmits forces and moments and determines the trajectory of the wheels. At the same time, it also has a certain friction damping effect. Three birds with one stone, so it is widely used in non-independent suspension.

The disadvantage of plate spring is that it can only be used for non-independent suspension, heavy weight, large stiffness, poor comfort, longer longitudinal size, is not conducive to shortening the car's front suspension and rear suspension, and the plate spring pin at the frame connection is easy to wear and so on.
