| 摘要 |
The present invention provides a tire assembling/disassembling machine, particularly for industrial vehicle wheels, having a support frame ( 2 ) delimiting a foreheadt, a back and two sides, a rigid support framework ( 13 ) articulated at the back of the support frame ( 2 ) according to an articulation axis ( 12 ), driving means ( 15 ) for angularly lifting/lowering said rigid support framework ( 13 ) with respect to said support frame, a self-centering assembly ( 14 ) overhangingly carried by said rigid support framework ( 13 ) at the foreheadof said support frame ( 2 ), whereby its axis of rotation is substantially normal to said articulation axis ( 12 ), and bead-releasing means carried by said rigid support framework. The tire assembling/disassembling machine further comprises a pair of side bead-releasing assemblies ( 34, 42 ), supported by said rigid support, framework ( 13 ) and each located on the opposite side with respect to said self-centering assembly ( 14 ), driving means ( 25, 26 ) for each bead releasing assembly ( 34, 42 ) designed to move its respective bead-releasing assembly ( 34 or 42 ) between a rest position and a working position in a substantially normal direction with respect to said articulation axis, and a fitting tool ( 47 ) overhangingly supported by one of said bead-releasing assemblies ( 42 ), thereby being angularly displaceable with respect thereto and to said self-centering assembly ( 14 ). |
