Vehicle-mounted generator mounting rack capable of isolating vibration transmission

The invention discloses a vehicle-mounted generator mounting rack capable of isolating vibration transmission, and belongs to the field of damping design. The damping device comprises a damping tableand four supporting legs arranged in the circumferential direction. A bottom-layer damping frame, a middle-layer damping frame, a generator mounting table and a fixing frame are sequentially arrangedon the damping table in parallel from bottom to top and are supported through springs and positioning rods; the supporting legs are of a telescopic structure, the upper portions of the supporting legsare fixed to the middle-layer damping frame through supporting lug bases, and the lower portions of the supporting legs can extend downwards in the axial direction to be used for damping supporting when the generator is used. The bottom-layer shock absorption frame is mainly used for buffering the influence of shock on the middle-layer shock absorption frame, the generator mounting table, the generator and the supporting l
