Abstract

A module ( 25 ) for measuring at least one parameter of a tire of a wheel of a motor vehicle, the wheel having a wheel rim ( 1 ). The measurement module ( 25 ) includes an inflation valve ( 30 ) designed to be assembled on the wheel rim ( 1 ) and including a deformable body ( 32 ) and a hollow rod ( 31 ) passing through the body ( 32 ) including an assembly notch ( 36 ) and a sensor device ( 40 ), mounted slidingly on the hollow rod ( 31 ), including at least one sensor for measuring the value of the parameter and an element ( 42 ) for immobilizing the sensor device ( 40 ) in the assembly notch ( 36 ). The assembly notch ( 36 ) has a setting range enabling the movement of the immobilizing element ( 42 ) in the assembly notch ( 36 ) between a first setting position and a second setting position to adapt to the thickness of the wheel rim ( 1 ).

First claim

1 . A module ( 25 ) for measuring at least one parameter of a tire of a wheel of a motor vehicle, said wheel comprising a wheel rim ( 1 , 1 A, 1 B, 1 C), said measurement module ( 25 ) comprising:
an inflation valve ( 30 ) designed to be mounted on said wheel rim ( 1 , 1 A, 1 B, 1 C) and including a deformable body ( 32 ) and a hollow rod ( 31 ) passing through said body ( 32 ), said rod ( 31 ) having an assembly notch ( 36 ), a sensor device ( 40 ), assembled slidingly on said hollow rod ( 31 ), including at least one sensor for measuring the value of said parameter and means ( 42 ) for immobilizing the sensor device ( 40 ) in said assembly notch ( 36 ),
wherein the assembly notch ( 36 ) has a setting range (Jr) enabling the movement of said immobilizing means ( 42 ) in the assembly notch ( 36 ) between a first setting position (Pmax) and a second setting position (Pmin) to adapt to the thickness of the wheel rim ( 1 , 1 A, 1 B, 1 C).

2 . The measurement module as claimed in claim 1 , wherein the setting range (Jr) is between 2 mm and 7 mm.

3 . The measurement module as claimed in claim 1 , wherein the assembly notch ( 36 ) has a first edge ( 36 A) defining the first setting position (Pmax) and a second edge ( 36 C) defining the second setting position (Pmin), the first edge being a retaining stop for the sensor device ( 40 ) on the rod ( 31 ) of the valve ( 30 ).

4 . The measurement module as claimed in claim 3 , wherein the second edge ( 36 C) is designed to enable the immobilizing means ( 42 ) to move into and out of the assembly notch ( 36 ) when the sensor device ( 40 ) is sliding on the rod ( 31 ).

5 . The measurement module as claimed in claim 3 , wherein the assembly notch ( 36 ) includes an adjustment plane ( 36 B) between the first edge ( 36 A) and the second edge ( 36 C).

6 . The measurement module as claimed in claim 5 , wherein, since the rod ( 31 ) extends along a longitudinal axis (XX), the adjustment plane ( 36 B) is substantially parallel to the longitudinal axis (XX).

7 . The measurement module as claimed in claim 1 , further comprising a delivery notch ( 37 ) able to receive the immobilizing means ( 42 ) before assembly of the measurement module ( 25 ) on a wheel rim ( 1 , 1 A, 1 B, 1 C).

8 . A motor vehicle wheel rim ( 1 ) comprising a measurement module ( 25 ) as claimed in claim 1 , mounted on said wheel rim ( 1 ).

9 . A vehicle comprising at least one wheel rim ( 1 , 1 A, 1 B, 1 C) as claimed in claim 8 .

10 . A method for assembling a module ( 25 ), as claimed in claim 1 , on a wheel rim ( 1 , 1 A, 1 B, 1 C) of a wheel of a motor vehicle, said wheel rim ( 1 , 1 A, 1 B, 1 C) having an orifice for assembling an inflation valve ( 30 ) in an assembly position in which the wheel rim is mounted in a groove ( 35 ) of the inflation valve ( 30 ), the method comprising the following steps:
insertion of the inflation valve ( 30 ) into said orifice of the wheel rim ( 1 , 1 A, 1 B, 1 C), stretching of the deformable body ( 32 ) of the inflation valve ( 30 ) in order to mount same by force in the assembly orifice, sliding of the sensor device ( 40 ) on the rod ( 31 ) of the inflation valve ( 30 ) under the effect of the stretching of said deformable body ( 32 ), insertion of the immobilizing means ( 42 ) of the sensor device ( 40 ) into the assembly notch ( 36 ) of said rod ( 31 ), movement of the immobilizing means ( 42 ) in the assembly notch ( 36 ) until the inflation valve ( 30 ) is in the assembly position of same.

11 . The measurement module as claimed in claim 2 , wherein the assembly notch ( 36 ) has a first edge ( 36 A) defining the first setting position (Pmax) and a second edge ( 36 C) defining the second setting position (Pmin), the first edge being a retaining stop for the sensor device ( 40 ) on the rod ( 31 ) of the valve ( 30 ).

12 . The measurement module as claimed in claim 11 , wherein the second edge ( 36 C) is designed to enable the immobilizing means ( 42 ) to move into and out of the assembly notch ( 36 ) when the sensor device ( 40 ) is sliding on the rod ( 31 ).

13 . The measurement module as claimed in claim 4 , wherein the assembly notch ( 36 ) includes an adjustment plane ( 36 B) between the first edge ( 36 A) and the second edge ( 36 C).

14 . The measurement module as claimed in claim 13 , wherein, since the rod ( 31 ) extends along a longitudinal axis (XX), the adjustment plane ( 36 B) is substantially parallel to the longitudinal axis (XX).
