Abstract:
A machine for balancing rotating bodies, in particular motor vehicle wheels, by applying balancing masses onto a rotating application surface (11a) pertaining to the body, comprising:a support and rotation means (20) for supporting the body (10) and rotating it about its axis of rotation, first sensor means (30) for determining the axial position of at least one chosen transverse balancing plane (P1, P2) in which to apply the balancing mass, and the radial position of points on the application surface (11a) on the body (10) which lie in said balancing plane (P1, P2), second sensor means (40) for determining the angular position of the body (10), means for determining the imbalance factors on the body (10), a processor means arranged to process the data originating from the first and second sensor means and from the imbalance determination means and to determine the value of the balancing mass and the position of its point of application on the application surface (11a), a means (50) arranged to acquire images originating from the application surface (11a), and a display means (60) to display said images on a screen (61) accessible to the operator, the processor means being connected to said display means (60) and indicating on the screen (61) the position of the point of application of the balancing mass in relation to the image of the application surface (11a) by means of an optical sign (62) appearing visibly superposed on the image of the surface (11a) acquired by the means (50) arranged to acquire images and displayed on the screen (61) wherein the means to acquire images will also acquire an image of the balancing mass as it is moved to its point of application, and the display means will display the image of the mass on the image of the application surface and optical sign.
