Shaanxi Auto cab development background and development trend analysis: The domestic commercial vehicle cab on the development of design deficiencies mainly two aspects: First, local material strength margin larger cab, resulting in waste material; the second is in the car The actual use of the process sometimes insufficient cab local strength and reliability issues. Limit by a wide range of objective conditions, China's commercial vehicle manufacturers cab cab to a local area problems often take local reinforcement approach, which not only require multiple comprehensive road test to determine the effectiveness of structural improvement, and will lead to increased vehicle weight; in addition cab before, due to the lack of a theoretical analysis support for some improvement and optimization of the cab light structure, are often not well implemented effects.

After heavy truck cab wiring harness connector, etc. is completed, the operation of the power switch can control the main electrical cabinet internal power relay, the entire heavy truck cab electronics and detector power.
