A device for rotary movement of vehicle wheel mounting flanges in tire changing machines comprises at least one first hydraulic or pneumatic actuator (5) which is coupled so that it can oscillate to the frame (6) of the machine (4) and rotationally actuates, through successive arcs, an assembly (7) with two crown gears (8, 9) for alternate coupling which is connected to the rotation shaft (10) of the flanges. <IMAGE> |
