Zusammenfassung:	The utility model discloses an air bag type traction wheel which is used for traction machines in plastic machinery industry and which is composed of a wheel hub 1 and an outer wheel 2. The outer wheel 2 is made of elastic rubber through once injection moulding, the central part of the outer wheel 2 is provided with an inner opening cavity, and an annular elastic air bag 3 is installed in the opening cavity. The traction wheel with the structure can ensure pipes adjustable clamp force in the process of being pulled, which enlarges the contact faces between the traction wheel and the pipes to be pulled, and ensures the surfaces of the pipes to be pulled uniform and proper stress without deformation.
