Abstract
The present invention regards a group for bead releasing a tyred wheel and/or for thrusting a portion of a tyre (T) of a tyred wheel (TW), and such group comprises a base, a supporting column rising from the base, a tool-supporting arm extending from the supporting column and a bead releasing and/or thrust tool supported by the tool-supporting arm.
Claims25
A group for bead releasing a tyred wheel and/or for thrusting a portion of a tyre of a tyred wheel, which group comprises:
- at least one base,
- at least one supporting column rising from said at least one base,
- at least one tool-supporting arm extending from said at least one supporting column,
- at least one bead releasing and/or thrust tool supported by said tool-supporting arm,
- said at least one column being movably mounted on said at least one base and/or said at least one tool-supporting arm being movably mounted on said at least one column,
- said group further comprising actuation means arranged to move said at least one column with respect to said at least one base or said at least one tool-supporting arm or a segment thereof with respect to said at least one supporting column or to another segment of said at least one tool-supporting arm, so as to move said at least one tool-supporting arm between a first resting or working trim and a second working trim, so that said at least one bead releasing and/or thrust tool is moved between a first resting or working position and a second working position, in which second position said at least one bead releasing and/or thrust tool is inserted between a portion of a bead of a tyre and a portion of a respective edge of a wheel rim,
- wherein said group comprises adjusting means for adjusting the advancing stroke of said at least one tool-supporting arm or of a segment thereof, between said first resting or working trim and said second working trim, designed to adjustably vary the placement of said at least one bead releasing and/or thrust tool in said second working position.
4 more elements
A machine for mounting and/or dismounting a tyre on/from a wheel rim, comprising at least one base,
- at least one group for bead releasing a tyred wheel and for thrusting a portion of a tyre of a tyred wheel, which first group for bead releasing and thrusting includes at least one first supporting column rising from said at least one base, at least one first tool-supporting arm extending from said at least one first supporting column, at least one bead releasing and thrust tool supported by said at least one tool-supporting arm,
- at least one group for mounting a tyred wheel, which group for mounting includes at least one supporting upright rising from said at least one base, at least one third tool-supporting arm extending from said at least one supporting upright, at least one mounting tool supported by said at least one third tool-supporting arm, said at least one mounting tool having a working or operating side facing the same direction of said at least one bead releasing and thrust tool, so that said at least one bead releasing and thrust tool and said at least one mounting tool are designed to act simultaneously on the same circumferential bead of a tyre, and
- support and constrain means of a wheel rim of or for a tyred wheel set to support a wheel rim or a tyred wheel with rotation and symmetry axis,
- wherein said first column is angularly offset with respect to said upright around said rotation and symmetry axis by an angle between 60° and 100° with reference to a plane substantially orthogonal to the rotation and symmetry axis, so that said group for bead releasing and thrusting and said group for mounting are set to simultaneously operate on the same circumferential bead of a tyre to be mounted on a wheel rim, at respective portions of the support and constrain means and, thus, of a same circumferential bead of the tyre angularly offset for an angle between 60° and 100° with respect to one another.
