Tire condition sensor unit mounting arrangement
First Claim
1. A sensor unit for sensing a physical parameter of a tire mounted on a vehicle wheel rim, said sensor unit comprising:
- an element for detecting the parameter;
electronics for generating radio frequency messages conveying the value of the parameter;
an emitting element; and
an electrical energy source; and
characterized in that said sensor unit is incorporated in a box placed inside the space delineated by the rim and the tire and is fastened to a pin permanently joined to the rim and protruding toward the inside of the tire.

Abstract
An arrangement for provision of vehicle tire sensory information while a tire (12) is mounted on a wheel rim (10) of a vehicle. A sensor unit (16) includes a tire condition sensor (e.g., electronics 38), a signal transmitter (36), and a housing (20) that contains the sensor and the transmitter. The housing (20) has a mounting hole. A stud (18) is welded to the rim (10) and extends into the space bounded between the tire (12) and the rim (10). The stud extends through the mounting hole of the sensor housing (20). A retainer (e.g., 26) extends between the sensor housing (20) and the stud (18) such that the sensor housing is held fixed relative to the stud.

26. A method of attaching a tire condition sensor unit, which senses a tire condition parameter and which transmits a signal indicative of the sensed parameter, to a rim of a vehicle tire assembly, said method comprising:
-
welding a stud directly to the rim to extend into a space bounded by the rim and a tire of the tire assembly;
locating the tire condition sensor unit adjacent to the welded stud; and
engaging a retaining component between the welded stud and the tire condition sensor unit. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34)
