Balancing machine for vehicle wheels with analog to digital conversion and adjustable sampling frequency
First Claim
1. Balancing machine for vehicle wheels, comprising a supporting frame for gripping and rotation means for gripping and rotating a wheel to be balanced around a rotation axis, first detection means for detecting the unbalance of said wheel with respect to said rotation axis suitable and generating a first analog signal, second detection means for detecting at least one portion of the profile of said wheel suitable and generating a second analog signal, at least one conversion device connected to at least one of said first and said second detection means and suitable for converting at least one of said first and said second analog signal into a corresponding digital signal, a processing and control unit associated with said conversion device and suitable for processing said digital signal, and adjustment means for adjusting the sampling frequency of at least one of said first and said second analog signals.

Abstract
The upgraded balancing machine for vehicle wheels comprise a supporting frame for gripping and rotation means for gripping and rotating a wheel to be balanced around a rotation axis, a first sensor for detecting the unbalance of the wheel with respect to the rotation axis suitable for generating a first analog signal, a second sensor for detecting at least one portion of the profile of the wheel suitable for generating a second analog signal, at least one analog to digital converter associated with at least one of the first and the second detection sensors and suitable for converting at least one of the first and the second analog signal into a corresponding digital signal, a processing and control unit associated with the conversion device and suitable for processing the digital signal, and an adjustment unit for adjusting the sampling frequency of at least one of the first and the second analog signals associated with the conversion device. The adjustment unit responds to a first signal generated by a shaft encoder, and responds to a programmable timer, so that the frequency of the sampling operation can be altered.
