Quick mounting device with a centering effect for mounting a vehicle wheel on the axle of a balancing machine
First Claim
1. A quick mounting device having a centering effect for mounting a motor vehicle wheel on the axle of a balancing machine, a flange mounted permanently on the axle for friction engagement of the rim of the motor vehicle wheel, chucking devices for tightening the rim against the flange, a conical arrangement having an outside part with a cylindrical outside face for engagement in the centering hole of the motor vehicle wheel and a conical inside face and an inside part having an internal bore for placement of the inside part on the axle of the balancing machine and having a conical outside face shaped so it is complementary to the conical inside face of the outside part and resting against the latter, whereby the inside part of the conical arrangement is placed under tension in the direction of the centering hole by spring means, and a radial flange with a contact face for coming in contact with the rim of the motor vehicle wheel extending from the cylindrical outside face of the outside part of the conical arrangement, characterized in that the outside part (13) is formed by separate segments (23) held on the inside part (11) by resilient means that apply a tension force to the segments.

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.

7. A quick mounting device having a centering effect for mounting a motor vehicle wheel on the axle of a balancing machine, a flange mounted permanently on the axle for friction engagement of the rim of the motor vehicle wheel, chucking devices for tightening the rim against the flange, a conical arrangement having an outside part with a cylindrical outside face for engagement in the centering hole of the motor vehicle wheel and a conical inside face and an inside part having an internal bore for placement of the inside part on the axle of the balancing machine and having a conical outside face shaped so it is complementary to the conical inside face of the outside part and resting against the latter, whereby the inside part of the conical arrangement is placed under tension in the direction of the centering hole by spring means, and a radial flange with a contact face for coming in contact with the rim of the motor vehicle wheel extending from the cylindrical outside face of the outside part of the conical arrangement, characterized in that the outside part (13) is formed by separate segments (23) held on the inside part (11) by resilient means, said segments (23) have edges (27) directed radially inward so that they engage behind the opposing edges (26) of the inside part (14) of the conical arrangement and thus prevent segments (23) from slipping down axially from the inside part (11).
