<p>A method for balancing automobile wheel assemblies comprising pneumatic tyres, said method comprising introducing a viscous balancing composition into the tyre; mounting the wheel on a rotatable assembly; pressing a rotatable drum and the tread surface of the wheel in the rotatable assembly against one another with a static force F, the axes of rotation of the drum and the wheel assembly being essentially parallel; and driving the drum and/or the wheel assembly to rotation for a time period T; the force F and the time T being sufficient to cause the balancing composition to be distributed inside the tyre, thereby balancing the wheel assembly. The method may preferably be carried out on an apparatus comprising a rotatable assembly on which a wheel assembly comprising a rim and a pneumatic tyre may be mounted; a rotatably mounted drum having an axis of rotation essentially parallel to that of the rotatable wheel assembly, the axes drum and/or the rotatable wheel assembly being capable of being moved in a direction towards and away from one another; driving means for rotating the rotatable wheel assembly and/or the drum; spring means and dampening means for providing static force and dampening in a direction between the axes of rotation of the drum and the rotatable wheel assembly, respectively, and essentially at right angles to said axes; and spring means and/or dampening means mounted between the axis of rotation of the rotatable wheel assembly and the ground and/or between the axis of rotation of the drum and the ground.</p> |
