Delong cab body insulation measures. Low frequency sound insulation panel stiffness and damping properties of materials related to the quality of law follow IF sound insulation performance, the greater the surface density, the greater the amount of noise, and therefore meet the requirements under the control of body weight, an appropriate increase in the thickness of the door window glass, optimizing allocation body The key position siding (floor, cowl-based) can effectively improve overall body thickness insulation performance. The main role of the carpet is to isolate the incoming noise floor, the choice of materials is more variety, there are blankets composite film + PV, PV film + foam, carbon fiber composite materials + cotton blankets. Tests show that the lower increase areal density of felt or cotton blankets can effectively isolate the main sub-section line floor apertures incoming detector and heavy truck cab harness connected. ① Connect the controller harness, the harness wires composed by 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 harness Shandong heavy truck cab, the harness is heavy truck cab exterior pieces composed by wires, and is divided into Steyr, Oron luxury, Delong three, when used according to the different models can be replaced corresponding harness. 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 heavy truck cab, 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.
