TYRE INFLATION; TYRE CHANGING; CONNECTING VALVES TO INFLATABLE ELASTIC BODIES IN GENERAL; DEVICES OR ARRANGEMENTS RELATED TO TYRES ## Abstract The machine (1) for fitting and removing wheel tyres for vehicles includes: a bearing structure (2); a locking device (5) of a rim (C) of a wheel (R) for vehicles, associated with the bearing structure (2) and rotatable around a first rotation axis (X1); a tool carrier arm (10) associated mobile with the bearing structure and having at least a tool (11) for removing/fitting a tyre (P) from/on the rim (C); an auxiliary arm (12) associated mobile with the bearing structure and having a bead-pressing tool (13) suitable for facilitating the removal/fitting operations of the tyre (P) from/on the rim (C); wherein the auxiliary arm is associated rotatable with the bearing structure around a second rotation axis (X2) substantially parallel to the first rotation axis (X1), in correspondence to a hinging point (14) arranged below with respect to a resting surface of the rim defined by the locking device. ## Claims ### Claim 1 Machine (1) for fitting and removing wheel tyres for vehicles, comprising: at least a bearing structure (2); at least a locking device (5) of a rim (C) of a wheel (R) for vehicles, associated with said bearing structure (2) and rotatable around a first rotation axis (X1); at least a tool carrier arm (10) associated mobile with said bearing structure (2) and having at least a tool (11) for removing/fitting a tyre (P) from/on said rim (C); at least an auxiliary arm (12) associated mobile with said bearing structure (2) and having at least a bead-pressing tool (13) suitable for facilitating the removal/fitting operations of the tyre (P) from/on the rim (C); wherein said auxiliary arm (12) is associated rotatable with said bearing structure (2) around a second rotation axis (X2) substantially parallel to said first rotation axis (X1), in correspondence to at least a hinging point (14) arranged below with respect to a resting surface of said rim (C) defined by said locking device(5). ### Claim 2 (depends on 1) Machine (1) according to the claim 1, wherein said tool carrier arm (10) can be moved to remove/fit wheel tyres with a radius between a predefined maximum radius (RMAX) and a predefined minimum radius (Rmin), wherein the distance of said second rotation axis (X2) from said first rotation axis (X1) is defined by the following formula: 0≦d(X1,X2)≦RMAX where d(X1, X2) indicates said distance of the second rotation axis (X2) from the first rotation axis (X1) and R indicates said predefined maximum radius (RMAX). ### Claim 3 (depends on 1) Machine (1) according to claim 1, wherein said tool carrier arm (10) can be moved to remove/fit wheel tyres with a radius between a predefined maximum radius (RMAX) and a predefined minimum radius (Rmin), wherein said distance of the second rotation axis (X2) from said first rotation axis (X1) is defined by the following formula: 0≦d(X1,X2)≦Rmin where d(X1, X2) indicates said distance of the second rotation axis (X2) from the first rotation axis (X1) and Rmin indicates said predefined minimum radius (RMIN). ### Claim 4 (depends on 1) Machine (1) according to claim 1, wherein said auxiliary arm (12) comprises at least a substantially vertical portion (16). ### Claim 5 (depends on 1) Machine (1) according to claim 1, wherein said substantially vertical portion (16) has a lower section connected to said hinging point (14), below said resting surface, and an upper section connected to said bead-pressing tool (13), above said resting surface. ### Claim 6 (depends on 1) Machine (1) according to claim 1, wherein said auxiliary arm (12) comprises at least a substantially horizontal portion (15) associated rotatable with said bearing structure (2) in correspondence to said hinging point (14) and connected to said lower section of the substantially vertical portion (16). ### Claim 7 (depends on 1) Machine (1) according to claim 1, wherein said auxiliary arm (12) comprises at least an articulated portion (17). ### Claim 8 (depends on 1) Machine (1) according to claim 1, wherein said auxiliary arm (12) comprises at least an articulated portion (17) with said bead-pressing tool (13) and hinged to said upper section of the substantially vertical portion (16). ### Claim 9 (depends on 1) Machine (1) according to claim 1, wherein said auxiliary arm (12) comprises a movement arrangement (18) of said bead-pressing tool (13) along a substantially vertical direction between a raised position and a lowered position. ### Claim 10 (depends on 9) Machine (1) according to the claim 9, wherein said movement arrangement (18) comprise at least a linear actuator (19). ### Claim 11 (depends on 1) Machine (1) according to claim 1, comprising at least an automatic start device (21) of said movement arrangement (18) connected to said tool carrier arm (10) and suitable for being activated automatically in correspondence to a predetermined angular position of said auxiliary arm (12) to bring said bead-pressing tool (13) from said lowered position to said raised position.
