Abstract
A valve stem for mounting and supporting a tire pressure monitoring assembly includes a flange formed after insertion into the wheel rim for preventing movement caused by forces generated during wheel rotation.
Claims20
A tire pressure monitoring assembly comprising:
- an elastic valve stem including an inner portion, an outer portion and a cavity extending from the inner portion to the outer portion;
- a valve body disposed within the cavity and defining a bore;
- a sensor housing secured to the valve stem by a fastening member;
- and
- an anti-rotation feature disposed between the sensor housing and at least one of the valve body and the valve stem for preventing relative rotation of the sensor housing relative to the at least one of the valve body and the valve stem.
2 more elements
A valve stem assembly securable to a sensor housing and mountable within a vehicle wheel, the valve stem assembly comprising:
- an elastic valve stem configured for mounting within an opening of a vehicle wheel;
- and
- a valve body disposed within the elastic valve stem, wherein the valve body includes an air inlet portion and an outlet portion extending outward from the elastic valve stem, the outlet portion including a securing feature engageable with a fastener supported on a sensor housing.
A method of securing a tire pressure monitoring sensor assembly to a wheel rim comprising:
- inserting a valve stem comprising an elastically deformable material through an opening in a wheel rim;
- seating an inner portion of the valve stem against an inner surface of the wheel rim;
- and
- aligning an alignment feature of the valve stem with a mating feature on a sensor housing to define a relative orientation between the sensor housing and the valve stem.
