The invention discloses a high-resistance stable steering device of a semi-trailer tractor. The high-resistance stable steering device of the semi-trailer tractor comprises a lower pallet and an upper pellet, wherein the lower pallet is connected with the tractor; the upper pallet is connected with the semi-trailer tractor; the lower pallet is connected with the upper pallet; the upper pallet and the lower pallet can rotate relatively; and a steering mechanism which can rotate and is connected with semi-trailer wheels is arranged between the lower pallet and the upper pallet. When the lower pallet steers in a preset angle, the steering mechanism is connected with the lower pallet and rotates along with the lower pallet; and when the lower pallet rotates out of the preset angle, the steering mechanism is separated from the lower pallet and is connected with the upper pallet. The high-resistance stable steering device of the semi-trailer tractor is simple in structure, is practical and convenient and has high wear resistance; and the service life of the high-resistance stable steering device is prolonged.
