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 increase 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 once, different from the full trailer, the semi-trailer is a trailer whose axle is placed behind the biggest market of gravity of the vehicle (when the vehicle is uniformly loaded) and built 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 describes a car that has no power of a unique and is jointly carried by the key vehicle and driven by the key vehicle.
Briefly, the full trailer is connected to the truck in front by hooks. The semi-trailer is associated with the traction seat of the tractor through the traction pin shipping container floor. The normal container transport vehicle is just a typical semi-trailer train, and the rear loading part is the semi-trailer.
Additionally there are differences in use. Full trailers are mainly employed for short-distance transportation in factories, ports, docks, warehouses and other fields, while semi-trailers are mainly employed 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 etc
Dump type semi-trailer:
A vehicle by having an automatic dumping device in its compartment. Also called dumper and engineering vehicle, it comprises automobile chassis, hydraulic lifting mechanism, power take-off device and cargo compartment. In civil engineering, it often works along 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. Considering that the loading carriage can automatically dump at a particular 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 just a common transport machine.
Grid-type semi-trailer:
The van type semi-trailer series products are employed for the transportation of household appliances, light textile goods, coal, sandstone and other building materials as well as chart and plate goods. The vehicle body is constructed 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 fairly distributed. The X-shaped brace gets the characteristics of multi pull, heavy load and light weight. The vehicle top has closed type, push-pull open type, open type, open tarpaulin pole type, etc. it is simple 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 trunk protection design has reasonable cart accessories to facilitate operation. It's refitted or separately manufactured on the chassis of a truck type vehicle, which can be split into passenger van type and carriage type based on the different carriages. The passenger compartment and cab are generally integral structures, such as for instance 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 for instance van type significantly less than carload transport vehicles, refrigerated and insulated vehicles, etc. The specific structural form of the carriage varies in accordance with its function. The compartment of the refrigerated and insulated vehicle not only has the big event of a general compartment, but also has the big event 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 up with 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 split into box type Yunshi semi-trailer and type II chassis modified van. The car body is constructed 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 priced, convenient maintenance. It's not only the elastic element of the suspension, but additionally the guiding device of the suspension. It's hinged to the frame at one end, which transmits forces and moments and determines the trajectory of the wheels. At once, in addition, it includes 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 so it can only just be employed 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 simple to wear and so on.
CIMC Intermodal Equilink Co., Ltd has also made achievements in semi-trailer accessories. We have axle, suspension, plate spring, leg, device potential, air storage cylinder, coil, tire, relay valve, rope tightening device, spare tire lifter, pull rod, traction pin, brake pad and so on.
