ABSTRACT:
An automatic device (1) for mounting and dismounting a tire (100) onto/from the rim (201) of a wheel (120) associated with a tire-dismounting machine (100) comprising a lower base (101) on which are associated rotating support and locking means (102) of the rim (201) of a wheel, a pole (103) extending vertically associated with said base (101), a horizontal support arm (104) associated with said pole (103), said device comprising a mobile shaft (2b) that can slide vertically inside a pipe (2) supported so that it can slide horizontally on said arm (104), an articulated quadrilateral made up of a tire-dismounting tool (4), a pair of opposite connecting rods (13, 14) and a body (6) fixed to the lower end of the mobile shaft (2b), and a manoeuvring lever (7) articulated with said quadrilateral and suitable for deforming it to transmit the roto-translating motion to the tool (4) that goes from a seeking configuration to an extraction configuration of the bead (202′) from the rim (201).
