Abstract
Description
Technical Field
[0001] The utility model relates to a transfer case and a generator set, belonging to the technical field of generator sets. Background Art
[0002] Currently, most engineering vehicles use diesel generator sets. These typically use a direct connection between the engine and generator, and can only accommodate one high-power generator. This layout is simple in structure and single in function. When other electrical operations require it, a separate diesel generator system must be added, increasing vehicle costs and occupying interior space. This also increases exhaust emissions, significantly impacting the overall design and environmental requirements of engineering vehicles. These cannot meet the requirements for use in confined spaces with high emission requirements, limiting the application scenarios of diesel generator sets. Furthermore, the engine torque and power are both high. Installing a high-power, high-torque engine on a special-purpose vehicle results in high fuel consumption and noise during driving, and the input and output speeds are consistent, making it impossible to increase or decrease the speed according to actual needs.
