A wheel servicing machine includes a releasable swing arm clamp apparatus attached to a swing arm. The clamp engages a rod slidably attached to and extending from a slide bar mounted on the swing arm. The clamp includes a closed, or locked, position and an open, or unlocked, position. In the closed position, the apparatus includes a rod clamp that can be rotated about the rod for fine adjustment of the angular position of the swing arm. When the rod clamp is in the open position, the angular position of the swing arm can be coarsely adjusted by manually moving the swing arm about a pivoting arm joint. When the swing arm is moved near a desired position, the rod clamp can be closed and can be rotated about the rod in the closed position in some embodiments for fine adjustment of the swing arm angular position.

The tyre-changing machine (10) for fitting and removing vehicle wheels includes: a bed (12) for resting on the ground; a spindle (14) which extends from the bed (12) and on which is mountable a wheel (R) having a rim (C) and a tyre (PN) with two opposite flanks (F1, F2), the spindle (14) being configured to tighten the rim (C) on it and able to put in rotation the wheel (R) around an axis of rotation (A); and two bead breaking tools (32, 42) which are movable one towards the other in the proximity of the spindle (14) along a bead-breaking direction (Di) substantially parallel to the axis of rotation (A) of the spindle (14), the bead breaking tools (32, 42) having respective non-rolling contact surfaces (34, 44) able to contact and push in use the opposite flanks with the wheel (R) mounted on the spindle.
摘要:
A method of and an apparatus for fitting or removing a tire 4 of a vehicle wheel 1, in which at least one fitting or removal tool 5 is guided parallel to the axis 11 of the vehicle wheel 1 and the vehicle wheel 1 is moved controllably perpendicularly to its wheel axis 11 in dependence on a rim contour along which the fitting or removal tool 5 is to be guided at a small spacing.
摘要:
The present invention is related to a method and an apparatus for assembling a tyre (1) onto the rim (2) of a vehicle wheel or for disassembling a tyre (1) from the rim (2) of a vehicle wheel. There is provided an electric motor (3) for rotationally driving the rim (2) and the tyre (1) during the assembling or disassembling operation, tools (4, 5) for assembling or disassembling the tyre (1) onto the rim (2) or from the rim (2), measuring means (6, 15, 16, 18) for measuring the tyre temperature and/or forces acting on the tyre during the assembling or disassembling operation, and recording means (7) for recording on at least one data carrier the measured values of the tyre temperature and/or of the forces acting on the tyre during the assembling or disassembling operation.
摘要:
An apparatus for mounting and demounting a tire on and from a rim of a vehicle wheel. The apparatus comprises at least one fitting or removal tool for mounting and demounting the tire, and a control unit for controlling movement of the fitting or removal tool. A load measuring device measures the load applied on the tool while mounting or demounting the tire. A counterpart method comprises moving the fitting or removal tool towards or away from the vehicle wheel for mounting or demounting the tire to and from the rim, capturing the load applied to the tire by the fitting or removal tool, calculating the load applied to the tire by the fitting or removal tool while mounting or demounting the tire, and controlling movement of the fitting or removal tool on the basis of the load applied to the tire by the tool.
摘要:
An apparatus for tire-changing machines includes a base having a face turned upward, a supporting and locking platform for wheels, mounted rotating on such face around a rotation axis and defining a supporting and locking table, support means of tools extending upward from the base, the support means being movable along the base in a direction of movement perpendicular to the rotation axis, so as to move closer or away from the rotation axis.
摘要:
A method and an apparatus of determining geometrical dimensions of a motor vehicle wheel (rim/tire assembly) 1 by contact-less sensing, wherein the wheel is fixed on wheel receiving means 2 of a tire changer, that at least one light beam 21 is emitted on to the wheel or at least a part of the wheel, wherein the light beam reflected at the impingement area is detected, and wherein the directions of the emitted and reflected light beams are evaluated for determining the shape and/or position of the respective impingement area on the wheel.
