Heavy truck cab development goals: (1) economic objectives control Jinan heavy truck cab assembly, cost, schedule and user requirements (demand). (2) target control technology, technical specifications, design quality, process design quality, manufacturing quality. To achieve these objectives, China's heavy truck cab, in the design of modern design methods should be employed, through the implementation of the following to complete the objectives and tasks: First, technical support via computer simulation and modeling techniques; the second is to establish a scientific mechanism design process; third is to establish the scientific development platform. Detectors and heavy truck cab harness connected to the main points of the line parts. ① Connect the controller harness, the harness wires composed by Shandong heavy truck cab, mainly to electrical appliances action after heavy truck cab back to the corresponding lights on the control box to indicate whether the point of failure. ② front connector wiring harness, the harness is composed by the wires and into Steyr, Oron luxury, Delong three, when using the appropriate harness can be replaced according to different models. Now through improved seed has been integrated into the harness together, do not because of changes in models and frequent replacement of the front of the harness when so used, can reduce the detection time and can increase the life of the detector. These harnesses can be combined heavy truck cab left headlight, left turn signal, about small lights, front fog around the signal back to the detector. After processing by the internal detector circuitry, the display on the control box. Heavy truck cab cable harness, the harness is composed by the wires and into the harness and Steyr Delong, Oron luxury integrated harness species. This line is to provide power to the heavy truck cab line and associated control signals, and heavy truck cab signal back to the detector, after processing by the main control box, the display returns to the control box or heavy truck cab.
