摘要:
A mount and demount head configured as a housing affixed to a shaft of an OEM tire machine with a semicircular shaped shaft affixed to the housing. The shaft has a bulbous protrusion on a bottom end of the shaft with specific tapers. The shaft and the bulbous end have a flattened portion for following the contour of the rim. On the upper side of the bulbous end is the narrow semicircular shaft with a tapered top end, tapered to a widened shaft, which is affixed to the housing. A non-metallic insert is preferably inserted into a void in the flattened portion of the narrow semicircular shaft and bulbous end to protect the rim surface. Clamp adapters are used to clamp and hold small wheel assemblies whereby the clamp adapters are inserted over the OEM clamps to extend the clamp capability of the OEM tire machine.

A tire changing tool head, or a mount/demount head for a tire changing machine, includes a head body and a tongue member. The tongue member is pivotally attached to the head body at a pivoting joint. The tongue member includes a tongue shoulder and a tongue blade for engaging a tire bead during tire installation. The tongue member includes a non-metal material, such as a polymer, for preventing wheel rim damage in some embodiments. The head body includes a bead lifter tool protruding therefrom. In some embodiments, the head body and bead lifter tool include a metal material.

The invention concerns a method for mounting a tyre on a rim to form a motor vehicle wheel and for demounting a tyre from a rim with at least one fitting or removal tool, wherein images of the wheel (14) or the rim (12) are created by a vision system (21) and corresponding signals are sent to a computer (18; 28), wherein commands to move the at least one fitting or removal tool (16) are sent to the at least one fitting or removal tool (16) by the computer (18; 30), wherein the signals of the vision system (21) and the commands sent to the at least one fitting or removal tool (16) are correlated to define the position of the at least one fitting or removal tool relative to the rim contour and wherein the movement of the at least one fitting or removal tool (16) is guided in dependence on the performed correlation without contacting the rim surface. Furthermore, the invention concerns an apparatus for mounting a tyre on a rim to form a motor vehicle wheel and for demounting a tyre from a rim.

A machine for fitting and removing wheel tires for vehicles includes a bearing structure that supports a clamping and rotating device of the wheel rim for vehicles around a substantially vertical rotation axis, at least one tool supported by the bearing structure and suitable for the fitting/removal of a tire onto/from the rim, and a lifting arrangement adapted to position and remove the wheel onto/from the clamping and rotating device. The lifting arrangement includes a first framework that defines a substantially horizontal support surface for the wheel and is associated with the bearing structure and mobile between a lowered position in which it surrounds the clamping and rotating device at least partially and a raised position in which it is substantially higher than the clamping and rotating device, a second framework with a resting portion for the wheel and which is associated with and rotates along the bearing structure, and a moving device for the first and second frameworks.

A tire mounting apparatus includes a mounting head that is rotated by a drive shaft and slidably carries two adjusting plates. A push rod extends coaxially through the drive shaft, and a deflecting rod slopes laterally from the push rod through openings in the plates. The deflecting rod has two sloping actuating surfaces with different slope angles that engage in the openings of the plates to cause different sliding displacement of each plate by an axial actuation of the push rod. A bead deflector and a pressing roller are respectively mounted on the plates so they can be adjusted to different wheel rim diameters. A toggle lever and/or a pivot joint adjust a pivot angle of at least one of the tire mounting tools to remain tangential to the wheel rim circumference while it is slidingly adjusted to a different wheel diameter.

A tire changing machine for changing difficult to mount tires is provided. The machine utilizes various implements configured about the machine's chassis in such a way that they do not interfere with each other's operation. In this way, the machine enables an operator to effectively change various tires.
摘要:
A machine for fitting and removing vehicle wheel tires, comprising a supporting frame for elements for coupling and rotating a rim about a rotation axis and for a working arm provided with one end on which a working head is supported for fitting and removing a tire on and from the rim, the coupling and rotation elements being movably associated with the frame by interposing elements for movement on a plane that is substantially perpendicular to the rotation axis, the arm being movably associated with the frame by way of the interposition of first elements for translational actuation in a direction that is substantially parallel to the rotation axis of the rim, second actuation elements being interposed between the arm and the first actuation elements and being adapted to allow the arm to move between a first active end configuration, in which the working head is arranged proximate to the first actuation elements, and a second active end configuration, in which the working head is substantially spaced with respect to the first actuation elements.
摘要:
Automatic device for demounting a tire from the relative wheel rim including a demounting tool. The demounting tool can be positioned in a tire bead seeking and gripping position where the axis of the demounting tool is parallel to that of the frame or the demounting tool is rotated a first direction towards the center of the wheel rim. The tool can be positioned for extracting tire bead from the wheel rim in which the axis of the demounting tool is parallel to that of the frame or rotated a direction opposite to the first direction. The device further including a bar, to the end of which the tool is hinged in an intermediate position, and a connecting rod which at one end is hinged to one end of the tool, and at the opposite end is connected to the bar by a lever linkage, the bar being connected to an actuator for advancing it and withdrawing it.
