Inflating control device for vehicle wheels.

摘要

1. Apparatus for monitoring the inflation of a pneumatic tyre on a wheel of a vehicle which travels on the ground characterised in that it comprises, disposed at the location of the surface of the rim (2) of the wheel (1), opposite the tread portion of the tyre (3), means for permanent measurement of the flattening of the tyre on the basis of calculation of the deflection of the tyre, said means being formed by an emitting-receiving device (8) for emitting sound waves through the fluid inflating the tyre (3) towards the internal surface (7) of the tread portion and receiving the waves reflected by said surface, and by electronic means (81) for calculating the distance (D) between the rim (2) and the internal face (7) of the tread portion of the tyre, which is measured at the two ends (E1 and E2 ) of the diameter of the wheel (1) which is orthogonal to the ground (4).
