Special chassis for oil-electric hybrid driving sanitation truck

The invention discloses a special chassis for an oil-electric hybrid driving sanitation truck. The chassis comprises an engine, a front axle, a speed changer, connecting flanges, a transmission shaft, a generator, a clutch, an air cylinder, an alternating-current walking motor, a rear axle, a storage battery pack, a charging plug, an alternating-current walking motor controller, a whole truck controller, a generator controller, a driving work device motor and an accelerator pedal. The output end of the engine is connected with the speed changer, an output shaft of the speed changer is connected with a generator shaft through one flange and the transmission shaft, an engine shaft and an alternating-current walking motor shaft are connected through the clutch, the alternating-current walking motor is connected with the rear axle through the transmission shaft and one flange, the whole truck controller is connected with the storage battery pack, the charging plug, the alternating-current walking motor controller, the generator controller, the driving work device motor and the accelerator pedal through wires, and the generator controller is connected with the generator, the alternating-current walking motor controller and the alternating-current walking motor through wires. The special chassis has the advantages of being low in energy consumption and emission, and the occupied space of the engine is small.
