ABSTRACT:
A vibration pick-up unit for balancing rotating bodies such as vehicle wheels comprises a housing having a tubular guide communicating with the interior of the housing, a plunger rod disposed telescopically in the tubular guide for axial and rotary movement, a permanent magnet attached pivotally on an end of the rod for engagement with a vibrating member of a wheel suspension system arising on rotation of the wheel, a first mounting member disposed within the housing and cooperating operatively with the tubular guide, the first mounting member being movable in response to the vibrations of the suspension system, a second mounting member disposed within the housing adjacent the first mounting member, light means disposed in the second mounting member for generating a source of light, photo-sensitive means disposed in the first mounting member and being responsive to the light means for converting the vibrations of the suspension system into an electric sinusoidal signal and circuit means connected operatively to the photo-sensitive means. The circuit means generates electrical impulses to flash a stroboscopic light onto the rotating wheel in synchronism with the vibrations of the suspension system.
