A tired-wheel having a wheel-rim and a tire thereon is automatically serviced. The method includes loading the tired-wheel onto a motor-driven support mounted for rotation about an axis of rotation, centering the tired-wheel with respect to the axis of rotation, and holding it by means of the motor-driven rotatable support, urging the wheel-rim against the rotatable support by means of an urging device so as to make the tired-wheel rigid in rotation with the rotatable support, disassembling the tire from the wheel-rim by means of a pair of working arms, moving away the urging device and removing the disassembled tire, loading a new tire onto the wheel-rim, repositioning the urging device and urging the wheel-rim against the rotatable support, and mounting the new tire onto the wheel-rim by means of the pair of working arms.

The present invention relates to a rotatable wheel rim support group designed to be mounted on an assembling-disassembling machine (MT) having a base (10), a control shaft (9) extending upwards from the base (10), removable locking means (11) for the wheel rim (C) which is engageable, in use, on the control shaft (9) and with a side of the wheel rim (C), and actuating means (M) for the control shaft (9). The support group comprises at least one pair of annular plate-shaped members (2, 3), in use, designed to abut against the wheel rim on a side opposite to that of the removable locking means (11), the plate-shaped members (2, 3) being arranged facing and approachable to and retractable from one another about the control shaft (9), a plurality of friction engagement means (5, 6; 5a, 5b) disposed angularly displaced and partly formed in one of the annular plate-shaped members and partly in the other, each of the friction engagement means formed in a plate-shaped member being designed to cooperate with a respective friction engagement means on the other plate-shaped member of the pair, in order to retract the annular plate-shaped members when one of them is angularly displaced with respect to the other, and support and rotational motion transmission means (8, 8a) between the control shaft and one of the annular plate-shaped members (2, 3) of the pair of annular plate-shaped members.
摘要:
An automatic detector device for a tire assembling-disassembling machine having at least one support group (G) mounted for rotation about an axis of rotation of a tired wheel (9) whose bead is to be released, and at least one bead-releasing roll-carrying extending-retracting arm (T1, T2). Each arm (T1, T2) can be extended and retracted and suppports a respective bead-releasing roll (R1, R2). The arm (T1, T2) are located, in use, on opposite sides with respect to the tired wheel (9). The detector device further comprises a sensor member (3) movably supported at a respective bead-releasing roll (R1, R2), driving means (5) for each sensor member (3), so that it can be moved between a backward rest position and an extended working position, and control means (34) arranged to act in response to control signals generated by sensor member (3) in its working position.
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).
摘要:
A safety device for inflating an envelope at risk of bursting comprising: a tubular body, a piston element slidably and sealably mounted within at least one inner portion of the tubular body; at least one piston rod integral with the piston element and extending so as to protrude from a first end of the tubular body; an annular bottom member, located in the tubular body or at the first end of the tubular body and suitable for slidably guiding the piston rod and for closing the tubular body whereby delimiting an annular space together with the tubular body and with the piston; removable anchoring device suitable for acting at a protruding end of piston rod and for constraining the piston rod to a support; at least one inlet opening and at least one outlet opening formed in the tubular body at the annular space, in operation said inlet opening being suitable for being connected to a pressurize fluid source and the outlet opening being designed to be connected to the envelope to be pressurized; and a yielding retainer for holding in position the said piston element, so that in case of bursting, the unit formed by the tubular body and the annular bottom member can be moved longitudinally following a bursting impact with respect to the piston element in contrast with the yielding retainer.
摘要:
An apparatus for servicing a tired wheel for motor vehicles, which comprises a tire assembling-disassembling machine provided with a rotatable motor-driven support (3) for supporting a wheel to be handled, sensor means (4, 5) for controlling both the position of, and the load on, the rotatable support (3), urging locking means (6) designed to act on the middle portion of the wheel-rim to make the wheel rigid in rotation with the rotatable support (3), detecting means (7, 7a, 7b) designed to measure the size of the wheel-rim, and program control means (EC).
摘要:
The tire removing machine has a resting base, a hollow support rigidly connected to the base and provided with a supporting flange for supporting motor vehicle wheels. A hollow securing shaft extends in the base and protrudes from the support, perpendicularly to the flange. A wheel centering and securing cone is anchored to the securing shaft outside the flange. A traction pin is rotatably accommodated in the shaft and extends beyond the centering cone where it ends in a traction head. A tool-holder bar with tool for mounting and removing a tire is at least temporarily coupled to the traction head.
