The technology of lightweight flying wing box semi-trailer and three axle spread wing semi-trailer is mature

Description :

　　After the adjustment of the new national GB1589 policy, lightweight products have become the A choice for users. In response to this demand, Liangshan Trailer uses 3D modeling CAE analysis to comprehensively analyze the vehicle load, ensuring maximum vehicle strength and achieving scientific and rational weight reduction while ensuring vehicle safety and reliability. At the same time, in terms of lightweight accessory selection, Liangshan trailer is equipped with aluminum alloy accessories (aluminum alloy legs, aluminum alloy air storage cylinder, aluminum alloy toolbox, aluminum alloy steel ring, aluminum alloy side protection, aluminum alloy rear protection), etc., successfully reducing the weight of the whole vehicle by 800kg/unit, fully realizing the "dual breakthrough of product quality and self weight", leading the development trend of the industry first!

　　Flying wing semi-trailer is a semi-trailer with a guardrail structure for cargo loading. Widely used, mainly suitable for medium and heavy-duty and bulk cargo transportation, with strong applicability, it has become one of the medium and long-distance freight vehicles. The entire vehicle body is made of high-quality steel, advanced technology, and strict production and manufacturing. The vehicle structure is reasonable, the performance is reliable, the operation is simple, and the appearance is beautiful. The series of semi-trailer frames are all of a through beam structure, with longitudinal beams of a straight or goose neck type. The web plate height ranges from 400mm to 550mm and is welded with manganese plate. The longitudinal beam is automatically buried welded, and the frame is shot blasted. The crossbeam penetrates the longitudinal beam and is welded as a whole. The suspension adopts a non independent steel plate stamping rigid suspension, made of series steel plate springs and suspension supports; The structure is reasonable, with strong rigidity and strength, used to support loads and reduce impacts.

　　The design process of the vehicle model and fence structure is combined with the user's cargo category, and is reasonably designed to fully reduce the weight of the carriage under load conditions. The structure is simple and applicable, and easy to disassemble. The new version of technical requirements has been revised, and high-strength, lightweight, and high rail trailers have ushered in new opportunities, reducing investment costs for users and creating more profit value.? 2. Frame: A spatial frame structure composed of longitudinal beams and integral through type transverse beams welded together. It can balance the strength, stiffness, and toughness of the frame, with strong load-bearing capacity and no deformation. 3. The series of warehouse rack semi-trailer frames are all of the through beam structure, with longitudinal beams of the straight or goose neck type. The web height ranges from 400 to 500, the longitudinal beam is welded by automatic submerged arc welding, the frame is shot blasted, and the crossbeam penetrates the longitudinal beam and is welded as a whole. 4. Suspension system: adopting a new type of suspension system with high strength and strong impact resistance; The load of each axle is balanced, and the angle of the system pull rod is designed reasonably. During frequent bumps, the friction and sliding distance between the tire and the ground are reduced, effectively reducing tire wear. At the same time, the pull rod can be adjusted to adjust the wheelbase, effectively avoiding the phenomenon of tire running in and biting.
