Patent ID: 8286474

Claim:
An electronic module for measuring operating parameters of the vehicle wheel, comprising: an electronic unit ( 1 ), an inflation valve ( 2 ) of the â€œsnap-inâ€ type for securing the electronic unit ( 1 ) to a wheel rim ( 27 ), comprising: a valve body ( 3 ) made of an elastomeric material, equipped with a longitudinal axial bore ( 4 ) and intended to extend through an orifice ( 28 ) made in the rim ( 27 ), said valve body being made up of an elastically deformable stem ( 5 ) and of an abutment head ( 6 ) butting against the rim ( 27 ) and separated from the stem ( 5 ) by a neck ( 7 ) designed to be positioned airtightly in the orifice ( 28 ) formed in said rim, and a hollow tubular core ( 15 ) made of a rigid material, housing a shut-off mechanism and of dimensions suited to be housed in the bore ( 4 ) of the valve body ( 3 ) and to extend on either side in the continuation of said valve body, said tubular core being made up of two longitudinal portions ( 18 , 19 ) arranged relative to one another and in relation to the valve body ( 3 ) in such a way as to allow an elastic deformation of the stem ( 5 ) able to allow the inflation valve ( 2 ) to be mounted through the orifice ( 28 ) in the rim ( 27 ), and means of securing the electronic unit ( 1 ) and the inflation valve ( 2 ) to one another, said electronic module being characterized in that the means of securing the electronic unit ( 1 ) and the inflation valve ( 2 ) to one another comprise: a ring ( 20 , 20 â€²) secured to the electronic unit ( 1 ) and designed to be slidably mounted around the portion of the tubular core ( 15 , 19 ) that extends in the continuation of the abutment head ( 6 ) of the valve body ( 3 ), in a position of the electronic unit ( 1 ) in which the latter extends in the direct continuation of the inflation valve ( 2 ), and means ( 13 , 14 , 25 , 26 , 25 â€³, 26 â€³, 44 , 25 â€²â€³, 26 â€²â€³, 45 , 46 ) of assembling the ring ( 20 , 20 â€²) of the electronic unit ( 1 ) on the abutment head ( 6 ) of the valve body ( 3 ).
