Basic Composition of Balancing Machine
A balancing machine comprising a frame suspension-mounted on a bed via elastic supports, a shaft rotatably supported by said frame at two points spaced a predetermined distance apart and having a first end provided with means for locking a wheel, and a second end connected to drive means for rotating said shaft, and at least two force transducers fixed between the bed and the frame, wherein the drive means comprise an electric motor fixed to and supported by the suspension-mounted frame, between the bed and frame there being interposed an elastic support comprising at least two coplanar leaf springs symmetrical about the axis of the shaft and positioned in a plane perpendicular to the plane containing the axis of said drive means, the axis of said shaft and said transducer means.
A machine as claimed in claim 1, wherein said drive means include a belt transmission.
A machine is claimed in claim 1, wherein the force transducers are applied on the same side of the shaft.
4. A machine as claimed in claim 1, wherein the force transducers are applied on opposite sides of the shaft.
5. A machine as claimed in claim 1, wherein the force transducers are spaced apart at a minimum distance feasible.
6. A machine as claimed in claim 1, wherein the force transducer means are applied directly between the frame and the bed.
