The present invention relates to an apparatus for attaching or detaching a commercial vehicle tire hub drum. According to the present invention, the apparatus for attaching or detaching a commercial vehicle tire hub drum may comprise: a main body frame 100 having traveling wheels 110 mounted on a lower part thereof; a holding means 200 formed so as to face forward from the main body frame 100 for holding upright a circular load mounted on a commercial vehicle; an attachment/detachment means 300 for executing an attachment/detachment operation of the load from above the holding means 200; and a position adjustment device 400 coupled to the main body frame 100 to adjust the position of the holding means 200 and the attachment/detachment means 300. Accordingly, the present invention provides an apparatus for attaching or detaching a commercial vehicle tire hub drum, which, by using a hydraulic device providing a hydraulic driving force, can conveniently attach or detach a load of various sizes to a vehicle from a fixed position while simultaneously adjusting the vertical position of a load-holding means.

A device for mounting and removing a tire on/from a rim includes a pincers element which is pivoted in a tool body with respect to the main frame and can grip a tire bead; the pincers element performs a preset rotation together with the tool body, moving away from the rim edge by performing a motion over the edge without making contact with the rim at the end of the rotation; the pincers element releases the bead on the outer edge of the rim, in a removal operation, or in the inner seat of the rim, in a mounting operation.

A fixture for eccentric clamping of a wheel is composed of a base (1), a cylinder (2), a cylinder support (3), a connecting seat (4), a movable positioning seat (5), a guide rail sliding seat (6), a linear guide rail (7) and a fixed positioning seat (8), wherein the cylinder support (3), the linear guide rail (7) and the fixed positioning seat (8) are fixed on the base (1), the cylinder (2) is mounted on the cylinder support (3), an output shaft of the cylinder (2) is connected with the connecting seat (4), the connecting seat (4) is connected with the linear guide rail (7) via the guide rail sliding seat (6), the movable positioning seat (5) is fixed on the connecting seat (4), and the cylinder (2) is configured to drive the connecting seat (4) and the movable positioning seat (5) to move along the linear guide rail (7).

An apparatus enables a commercial vehicle tire hub drum to be attached and detached. The apparatus includes a main body frame having traveling wheels mounted on a lower part thereof and holding means that face forward from the main body frame for holding upright a circular load mounted on a commercial vehicle. An attachment/detachment means executes an attachment/detachment operation of the load from above the holding means. A position adjustment device coupled to the main body frame adjusts the position of the holding means and the attachment/detachment means. Accordingly, the apparatus uses a hydraulic device providing a hydraulic driving force to conveniently attach or detach a load of various sizes to a vehicle from a fixed position while simultaneously adjusting the vertical position of a load-holding means.

A fixture for eccentric clamping of a wheel is composed of a base (1), a cylinder (2), a cylinder support (3), a connecting seat (4), a movable positioning seat (5), a guide rail sliding seat (6), a linear guide rail (7) and a fixed positioning seat (8), wherein the cylinder support (3), the linear guide rail (7) and the fixed positioning seat (8) are fixed on the base (1), the cylinder (2) is mounted on the cylinder support (3), an output shaft of the cylinder (2) is connected with the connecting seat (4), the connecting seat (4) is connected with the linear guide rail (7) via the guide rail sliding seat (6), the movable positioning seat (5) is fixed on the connecting seat (4), and the cylinder (2) is configured to drive the connecting seat (4) and the movable positioning seat (5) to move along the linear guide rail (7).

The present invention relates to a device for dismounting a tired wheel having a wheel rim and a tire mounted on the wheel rim, including: a support member, a bill or lever-shaped dismounting tool having one end thereof articulated to the support member, and the other work end thereof substantially hook-shaped, and holding means for holding the tool in an engagement and extraction position, the holding means including an elastically loaded pin.

The present invention concerns a device for assembling-disassembling a tired wheel (TW) comprising a support component, an extension or stem component connected to the support component, a working tool articulated to the extension or stem component and actuation means intended to drive the sliding of the extension or stem component with respect to the support component.

Described is an operating head (1) for a tire changer machine (2), having a longitudinal axis (L) and a supporting element (9) elongate along a transversal axis (T) relative to the longitudinal axis (L) and facing in a first direction, wherein the supporting element of (9) has a protrusion projecting along an operating direction (W) substantially perpendicular to a reference plane containing the longitudinal axis (L) and the transversal axis (T), and wherein the operating head (1) has a drive element (10), elongate along the transversal axis (T) in a second direction opposite the first direction in which the supporting element (9) faces and a fin (11) protruding in the operating direction (W) to define a guide surface (11a) inclined relative to a plane which is perpendicular to the reference plane and contains the longitudinal axis (L).

A bead guide includes a columnar portion having a cylindrical side surface, and a guide plate extending from a distal end of the columnar portion. Through rotation of the bead guide, an expansion bar rotation driving section selectively switches the bead guide between a first position at which the guide plate is retreated radially inwardly from an outer circumferential end of a wheel, and a second position at which at least a part of the guide plate protrudes radially outwardly from the outer circumferential end of the wheel. The bead guide is switched from the first position to the second position so that the guide plate is caused to enter below an upper bead.
