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. |

1. An electronic unit for measuring operating parameters of a vehicle wheel, comprising:
an inflation valve (2) including, on the one hand, a valve body (3) intended to extend through an orifice arranged in a wheel rim, and comprised of a trunk (4) and an abutment head (5) against the rim, and, on the other hand, a rigid hollow tube (10) extending in the continuation of the abutment head (5), an electronic module (1) adapted to be mounted in a slidable manner around the rigid tube (10), and means for securing the electronic module (1) and the inflation valve (2) in a position, known as the locked position, of said electronic module, where the latter extends in the direct continuation of the abutment head (5) of said inflation valve (2), said means for securing comprising means of locking including devices (11a, 11b, 18) for the relative locking in translation of the electronic module (1) along the rigid tube (10), 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 electronic unit, said electronic unit being characterized in that the electronic module (1) and the abutment head (5) of the inflation valve (2) comprise: two complementary front faces (7, 13) adapted in order to come into correspondence in the locked position of the electronic module (1), at a predetermined minimum distance one from the other that is identical for all the preselected widths of rims intended to be equipped with the electronic unit, devices (8, 16) for the optical tracking of the longitudinal position of the electronic module (1) along the rigid tube (10), adapted to permit verification of whether the distance separating the two complementary front faces (7, 13), in the locked position of said electronic module, corresponds to the predetermined minimum distance. |
