Abstract: A vehicle wheel balancing machine having a rotating shaft which supports a vehicle wheel, a means for supporting the rotating shaft, and force sensor means adapted to detect the imbalance forces generated during the rotation of the rotating shaft; an accelerator means accelerates the shaft and the wheel and an angular sensor means senses an angular position; an electronic means processes information obtained by the force sensor means and determines the value and the position of correction masses adapted to compensate an imbalance present on the wheel; a moving indicator means is moved by a motorized actuator means and is configured to project a light dot on the wheel; a fixed indicator means projects a luminous beam, perpendicular to the axis of rotation, or a luminous dot, having a fixed and known angle of incidence on the inner surface of the wheel; a coincidence of the moving luminous point with the fixed luminous line or dot identifies a desired position of a counterweight on the diameter of the wheel.

Abstract: A method for measuring the dimensions and characteristic angles of wheels, steering system and chassis of vehicles by means of an apparatus comprising a plurality of 3D scanners, functionally connected to a computer and arranged peripherally to a vehicle whose dimensions and characteristic angles of wheels, steering system and chassis are to be measured; each one of the 3D scanners having a viewing field, the merging of the viewing fields defining a viewing field of the apparatus; the method is characterized in that it comprises: a total measurement step, in which all the wheels of the vehicle are at least partially visible in the viewing field of the apparatus; and a partial measurement step, in which at least one wheel of the vehicle is not visible in the viewing field of the apparatus.

Abstract: 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.

Abstract: Alignment device adapted to measure characteristic angles of the wheels and of the steering of motor vehicles, particularly camber, toe-in, caster, by way of arms provided with sensors to be fastened to the wheels. In particular, in the step for determining the mounting error of the grip elements (runout), the level sensor is used to measure the wheel rotation angle and methods for compensating the measurements performed when the arms are at a nonzero level are then applied.
