A support for a device for inspecting a set of wheels includes a mounting frame that carries a device for mounting the frame on a respective wheel. Another device carried by the frame thrusts against the wheel a plate provided with a series of bearing pegs parallel to an axis of the support.

Support for a device for inspecting a set of wheels

The wheel (3) to be balanced is mounted on a rotatable shaft carried by two spaced bearings (6, 4) provided with force sensors ( 8, 10). Two standard weights are mounted on the wheel rim at two points spaced angularly apart. The sensors (8, 10) signal the forces exerted on the bearings by the rotation of the wheel equipped with said weights. The weights are then removed and a new measurement ofthe forces exerted on the bearings is made. The values and the positions of the correcting weights to be placed on the wheel are then determined from the characteristic relationship of the wheel-apparatus assembly obtained by comparison of the results of these two measurements.

Process and apparatus for balancing a vehicle wheel

The balancing machine comprises a shaft (2) mounted on a frame (1) by means of two bearings (3, 4), under each of which a force sensor (5, 6) is mounted. The shaft (2) is driven by a motor (10) and a chain transmission. The chain (16) of this transmission has a pulling side which is taut and at right angles to the plane passing through the axes of sensitivity of the sensors (5, 6), while its driven side is slack.
