Description

Technical Field

[0001] The present invention relates to the technical field of vehicle chassis, and in particular to a dual-power special vehicle chassis. Background Art

[0002] In recent years, with the rapid development of the national economy, the special vehicle industry has also witnessed rapid development. There are a wide variety of special vehicles, and their operating conditions vary. At present, there are mainly three modes of power sources for the superstructures of special vehicles: power take-off from the chassis gearbox, superstructure auxiliary engine drive, and superstructure motor drive. However, there are the following problems: The power take-off from the chassis gearbox is the most economical, but the power take-off power is limited, and it is only suitable for special vehicles with a relatively small superstructure power or parking professional special vehicles. For parking operation special vehicles, the engine is only used to drive the superstructure during operation, generally taking power in neutral, and the engine speed changes according to the superstructure requirements, resulting in poor fuel economy; The superstructure auxiliary engine drive can be used for high-power superstructures, such as washing and sweeping vehicles. However, with the improvement of environmental protection requirements, the emissions of auxiliary engines need to be upgraded, and the cost of installing auxiliary engines is relatively high; The superstructure motor drive, with a high-power DC motor drive, has a relatively large power and is mainly applied to pure electric vehicles. Summary of the Invention
