Abstract

The invention concerns a device for mounting a sensor on a motor vehicle wheel rim (10) comprising: a truss rod (20), a housing (40) receiving the sensor, said housing being articulated relative to the truss rod (20), a means (30) for locking the truss rod in position on the rim (10) once the housing (40) is in contact with the rim (10). The invention is characterized in that said housing (40) includes a first stop element (80) designed to co-operate by contact with a first zone of the rim (10), said first stop element (80) being arranged on one side of a plane P passing through the hinge pin of the housing (40) and a second stop element (70) arranged on the other side of said plane and designed to press on the rim (10) under a force F exerted by the truss rod (20). The invention also concerns the mounting method associated with said device.

Claims

1. A device for mounting a sensor on a motor vehicle wheel rim (10), comprising:

a pulling piece (20),

a casing (40) accommodating the sensor, said casing (40) being articulated with respect to the pulling piece (20),

a means (30) for locking the pulling piece in position on the rim (10) once the casing (40) is in contact with the rim (10),

characterized in that said casing (40) comprises a first stop (80) designed to collaborate through contact with a first region of the rim (10), said first stop (80) being placed on one side of a plane P passing through the axis of articulation of the casing (40) and a second stop (70) placed on the other side of said plane and designed to press against the rim (10) under a force F exerted by the pulling piece (20).

2. The device for mounting a sensor as claimed in claim 1, characterized in that the length of the lever arm between the first stop and the axis of articulation of the casing (4) is short by comparison with the length of the lever arm between the second stop and said axis, which means that a large variation in the angular position of the casing (40) can be generated for a small translational movement of the pulling piece (20).

3. The device for mounting a sensor as claimed in claims 1 or 2, characterized in that the casing (40) comprises means (50) designed to limit its tilting to just one direction.

4. The device for mounting a sensor as claimed in claims 1 to 3, characterized in that the pulling piece (20) comprises a hook (100) collaborating with a spindle (90) placed in the casing (40).

5. The device for mounting a sensor as claimed in claims 1 to 3, characterized in that the pulling piece (20) comprises a spindle collaborating with a corresponding housing placed in the casing (40).

6. The device for mounting a sensor as claimed in claims 1 to 3, characterized in that the pulling piece (20) comprises a lug (100′

) collaborating with a corresponding inclined plane (90′

) placed in the casing (40).

7. The device for mounting a sensor as claimed in claims 1 to 6, characterized in that the pulling piece (20) consists of the tire inflation valve body, the base of which is designed to collaborate with the casing (40).

8. The device for mounting a sensor as claimed in claim 7, characterized in that the means for locking the valve on the rim (10) is a nut (30).

9. A method for mounting a sensor on a motor vehicle wheel rim (10), comprising:

a pulling piece (20),

a casing (40) accommodating the sensor, said casing (40) being articulated with respect to the pulling piece (20),

a means (30) for locking the pulling piece in position on the rim (10) once the casing (40) is in contact with the rim (10),

characterized in that it consists in bringing the casing (40) against the rim (10) under the effect of the tilting moment generated jointly by a pulling force F exerted on the pulling piece (20) and by the reaction exerted at a first stop (80) incorporated into said casing (40) and placed on one side of a plane P passing through the axis of the pulling piece (20) when said stop comes into contact with the rim (10), said tilting being halted by a second stop (70) incorporated into the casing (40) and coming into contact with the rim (10), which other stop is placed on the other side of said plane.
