ABSTRACT:
A quick mounting device with a centering effect for mounting a motor vehicle wheel on the axle of a balancing machine is provided with a flange permanently carried on the axle for frictional engagement of the wheel rim and with choking devices for tightening the rim against the flange. The quick mounting devices also includes a conical arrangement having an outer part with a cylindrical outer face for engagement with the centering hole of the motor vehicle wheel and with a conical inside face and with an inside part having an internal bore for placing the inside part on the axle of the balancing machine and having a conical outside face with a complementary shape to the conical inside face of the outer part, whereby the inside part of the conical arrangement is under tension from a spring, applying tension in the direction of the centering hole, and a radial flange with a contact surface for coming in contact with the wheel rim extends from the cylindrical outside face of the outside part of the conical arrangement. The outside part is formed by separate segments held on the inside part by means of resilient devices. The spreadable elements of the outside part of the conical arrangement are designed as segments that are completely independent of each other. They can move practically unhindered and in parallel over a large radial range without resulting in any jamming, twisting or excessive bending.
