Monitoring device for tyres for vehicle wheels, tyre for vehicle wheels provided with said monitoring device, and method for installing an electronic unit in said tyre

Abstract

A monitoring device for tires for vehicle wheels includes: an electronic unit; a connecting member configured for constraining the electronic unit to a tire, the connecting member including: a first and a second base portion, mutually separated by a separated region, each of the base portions having a respective base surface associable with an inner surface of a tire; a housing portion associated with the base portions defining, in cooperation with said base portions, a cavity for housing the electronic unit, wherein the housing portion includes at least one side structure, configured for exerting a containing action at least relative to movements of the electronic unit carried out in a major extension direction of the separation region and with respect to movements of said electronic unit carried out in a direction orthogonal to the major extension direction of the separation region wherein the cavity is confined at least by a side surface defined by an inner surface of the side structure, wherein the electronic unit includes at least one sensor, at least one antenna and a holding body for housing at least the sensor and the antenna, wherein the holding body has at least one side surface, wherein, when the electronic unit is inserted in the cavity: the side surface of the holding body faces the side surface of the cavity, and the sizes of said cavity and of the holding body are such as to form at least one first gap at least partly separating the side surface of the holding body and the side surface of the cavity.
