Support for an electronic box used for monitoring the tire pressure, mounted on a wheel rim of a motor vehicle

Abstract

A support ( 11 ) that is mounted on a wheel rim of a motor vehicle in order to fasten an electronic box ( 10 ) used for monitoring the tire pressure. The support includes: a central part that is fixed to the rim; a first end which is provided with attaching elements for receiving a rotating shaft fastened to a first end of the box that is to be fixed; and a second end ( 18 ) that is provided with a plurality of elastically deformable retaining element ( 20, 25 ) for fixing a second end ( 17 ) of the electronic box to the support ( 11 ), each retaining element ( 20, 25 ) counteracting a specific force that is applied to the box.

1 . A support ( 11 ) mounted on a rim ( 13 ) of a motor vehicle, to hold in position an electronic unit ( 10 ) for monitoring tire pressures, said support being characterized in that it comprises: 
 a central part ( 11   a ) secured to the rim,    a first end ( 14 ) equipped with catching means ( 16 ) accepting a pivot pin (A) secured to a first end ( 15 ) of the unit that has to be secured, and    a second end ( 18 ) equipped with a plurality of elastically deformable retaining means ( 20 ,  25 ) for securing a second end ( 17 ) of the electronic unit to the support ( 11 ), each retaining means ( 20 ,  25 ) being designed to counter a specific force exerted on the unit.    
   
   
       2 . The support as claimed in  claim 1 , characterized in that the plurality of retaining means consists of a central device ( 20 ) with an elastic push fit combating the centrifugal force and of a pair of lateral devices ( 25 ) with an elastic push fit combating the stresses of vibrations and shocks transmitted to the unit as the rim rotates, said lateral devices ( 25 ) also being designed to immobilize the central device ( 20 ) under stress and to press the electronic unit ( 10 ) firmly against the support ( 11 ).  
   
   
       3 . The support as claimed in  claim 2 , characterized in that the lateral devices ( 25 ) stress the central device against the unit by applying a tension more or less at right angles to the central device.  
   
   
       4 . The support as claimed in  claim 1 , characterized in that the central device and the pair of lateral devices are made as one single component.  
   
   
       5 . The support as claimed in  claim 1 , characterized in that it is made of steel sheet through a pressing operation.  
   
   
       6 . The support as claimed in  claim 2 , characterized in that the central device and the pair of lateral devices are made as one single component.  
   
   
       7 . The support as claimed in  claim 3 , characterized in that the central device and the pair of lateral devices are made as one single component.  
   
   
       8 . The support as claimed in  claim 2 , characterized in that it is made of steel sheet through a pressing operation.  
   
   
       9 . The support as claimed in  claim 3 , characterized in that it is made of steel sheet through a pressing operation.  
   
   
       10 . The support as claimed in  claim 4 , characterized in that it is made of steel sheet through a pressing operation.
