The utility model discloses a spring damping, turnover and jolt prevention two-level chassis structure. The chassis structure comprises a main engine system, a first level chassis, a second level chassis, a plurality of first dampers and a plurality of second dampers. The main engine system is installed on and fixedly to the second level chassis. The first dampers are fixed between the main engine system and the second level chassis. The second level chassis is installed on and fixed to the first level chassis. The second dampers are fixed between the first level chassis and the second level chassis. The two chassis and the two dampers are arranged, the two dampers work at the same time, the damping effect is very obvious, losses of the main engine system caused by vibration are greatly reduced, noise generated in the operating process of the main engine system is lowered, and a power station is made to stably operate in a hidden mode; the two chassis are designed, added space is small, convenience of the power station is guaranteed, and the chassis structure can be suitable for the war industry.
