As an important part of the automotive parts field, the quality of unpowered trailer for outdoor use directly affects the quality and performance of the product, and there are many difficulties and key points of quality control.
In terms of assembly process difficulties, the first is the precise matching of parts. Unpowered trailers contain many parts, such as frames, axles, wheels, suspension components, etc., and the dimensional accuracy of these parts is extremely high. A slight deviation may lead to assembly difficulties. For example, at the connection between the frame and the axle, if the matching tolerance of the aperture and the axle diameter exceeds the range, it will cause jamming during assembly or even failure to install, affecting production efficiency and product quality.
Secondly, the assembly of the suspension system is more complicated. In order to adapt to complex outdoor terrain, the suspension system usually has a certain degree of elasticity and adjustability. During the assembly process, it is necessary to ensure that the shock absorbers, springs and other components are installed correctly and the preload is appropriate, otherwise it will cause the trailer to have problems such as excessive bumps and poor driving stability during driving.
In addition, sealing and waterproof assembly is also a major challenge. The outdoor environment is changeable, and rain, mud and sand can easily invade the interior of the trailer, damage the goods or corrode the parts. Therefore, when assembling parts such as car body joints and lamp seals, high-quality sealing strips and sealing processes must be used to ensure the overall waterproof and dustproof performance.
For key points of quality control, raw material inspection is the first priority. Strict quality inspection of each component entering the assembly process, including material strength, hardness, surface quality, etc., to prevent unqualified products from entering the production line, is the basis for ensuring the quality of the trailer.
Each process in the assembly process must have a strict inspection process. For example, after the frame welding is completed, flaw detection should be carried out to ensure that there are no defects such as cracks and cold welding at the welding point; after the tire is installed, the tire pressure, balance and installation firmness with the wheel hub should be checked.
In addition, the performance test of the whole vehicle is an important part of quality control. By simulating different road conditions and load conditions, the trailer's traction stability, braking performance, driving stability, etc. are tested. Only when all performance indicators meet the standard requirements can the product be judged to be qualified for shipment.
In short, only by overcoming the difficulties in the assembly process of unpowered trailers for outdoor use and firmly grasping the key points of quality control can we produce high-quality and high-performance unpowered trailers to meet the diverse needs of outdoor travel and transportation and occupy a place in the fierce market competition.
