The purpose of the cab interior design is to eliminate indoor sound absorption reverberant sound-absorbing material absorption coefficient, the greater the sound absorption area, eliminating the car reverberant the better. Delong cab cab interior acoustics package primarily for roof sidewall material and carpet materials, common roof sidewall trim for hemp fiber, are porous sound-absorbing material, the main role is to remove the car reverberant by increasing the thickness, porosity increase the absorption coefficient can be increased heavy truck cab, you can also paste the cover on the back of a certain thickness of the local auxiliary sound-absorbing cotton blankets position. In addition to considering the car interiors sound absorption properties of the material itself, but when the material is disposed in the key hole joints, splices to do the transition seal the deal, and try to ensure that the material and the inner wall can fit tightly. Engine heat pad attached to cover the floor, insulated glass mat material asbestos, felt material, loose materials such as cotton, its main role is to cut off the engine surface heat transfer to the cab, while both surface radiation absorption isolate engine sound effects . Taking into account environmental issues China's heavy truck cab, engine insulation glass mat should abandon the use of some asbestos materials. Heavy truck cab design ideas Harness Tester The instrument is designed and developed on the basis of Steyr series, Oron luxury series, Delong Series models on electrical principles, the basic idea is to simulate the design of the frame signal and provide heavy truck cab to the circuit, after homemade harness connection, heavy truck cab signal back to the detector monitors, heavy truck cab signal board, heavy truck cab interior electrical equipment, and through this section to reflect heavy truck cab circuit is normal. Testing and maintenance personnel through the instrument can easily be static and dynamic testing Shandong heavy truck cab, combined with related models, electrical schematics, and remove electrical fault heavy truck cab. The detector provides DC power requirements, but the design of the production process, in the main control box inside the reserved space and fixed position, according to the power supply needs to be installed, so you can make the instrument suitable for different places, improve equipment mobility and flexibility. The instrument has an internal power switch a two-phase, has a main power switch (located on the instrument control box outside) heavy truck cab exterior parts on the line, after turning on the switch cocaine seed to start using the detector . On the handheld control box is also equipped with a main power switch, the switch can be controlled detector main control box power relay, when you begin to detect heavy truck cab harness, simply operate the switch. The circuit is also provided with a circuit breaker to protect the circuit safety. Breaker into the outlet end of the road, all the way to the main control box power detector; the main sub-segment line detector and heavy truck cab harness connected.
