Traction device and traction method of rodless electric tractor

The traction device of the rodless type electric tractor comprises a U-shaped channel steel frame, two first mounting grooves are symmetrically formed in the channel steel frame, two mounting plates are evenly distributed at the top ends of the two first mounting grooves, steering mechanisms are arranged on the four mounting plates, and the steering mechanisms are arranged on the two mounting plates. The steering mechanism comprises a first transmission wheel rotationally installed at the bottom of the installation plate, a fixing plate is fixedly installed at the bottom of the first transmission wheel, two symmetrically-formed installation holes are formed in the fixing plate, and a second motor located under one installation hole is fixedly installed at the bottom of the fixing plate. The invention further discloses a traction method of the rodless electric tractor. According to the four-wheel drive tractor, larger traction force can be provided through four-wheel drive, an airplane with larger weight can b
