Electronic unit for measuring operating parameters of a vehicle wheel, comprising an electronic module and an inflation valve

Abstract

The electronic unit includes an inflation valve adapted to be secured to a wheel rim and including an abutment head against the rim, extending in the continuation of which are a rigid tube, an electronic module mounted in a slidable manner along the tube, and elements for the relative locking in translation of the module along the tube, defining at least two positions of relative locking, each adapted to correspond to a preselected thickness of the rim intended to be equipped with the unit. The module and abutment head include two complementary front faces adapted in order to come into correspondence at a predetermined minimum distance from each other that is identical for all the preselected widths of rims intended to be equipped with the unit. Optical tracking devices are provided to permit verification of whether the distance separating the two complementary front faces corresponds to the predetermined minimum distance.
