Tyre incorporating a measuring device

摘要

The tyre contains a force detector in the shape of a nail with a rigid rod (1) and a head (2) containing a deformable element that responds to force or stresses when the rod is moved and is equipped with measuring devices and anchoring points. The tyre contains a force detector in the shape of a nail with a rigid rod (1) and a head (2) containing a deformable element that responds to force or stresses when the rod is moved and is equipped with measuring devices and anchoring points. The deformable element is based on materials such as silicium, quartz or metal and can be in the form of a solid circular membrane or arms radiating from a central zone. The anchoring points can be separate or in the form of a continuous ring. The measuring devices can be piezoelectric or piezoresistive gauges or condensers with one electrode in contact with the deformable elements. The detector is located inside the tyre tread and can be linked to an accessory of larger size, made from a metal, polymer or ceramic material.
