Abstract: A tire monitoring device includes a housing mounted within a cavity of a tire/wheel assembly. A sensor within the housing senses a condition within the cavity via an open passage in the housing. A hollow first tube extends away from the housing coaxial to an axis of the open passage. The first tube has an internal bore aligned with the open passage, and includes: a first tubular portion having a first cross sectional width; and a second tubular portion having a second cross sectional width smaller than the first cross sectional width. The second tubular portion further has a free end opening positioned in the cavity above a level of a liquid present in the cavity when the tire monitoring device is positioned at a lowest point in the cavity. The opening has a cross sectional width sized to prevent entrance of the liquid past the opening.
Abstract: A tire pressure sensing system includes a tire patch having first and second faces. A plate fixed to the second face is oriented perpendicular to a tire patch longitudinal axis. A sensor mount is positioned on the first face and oppositely facing with respect to the plate. The sensor mount includes opposed first and second bias clips and is oriented perpendicular to the tire patch longitudinal axis. At least one plate fastener extends through the tire patch fixes the plate to the second face and the sensor mount to the first face. A tire pressure sensor is releasably retained by first and second sensor fasteners and the first and second bias clips to the sensor mount. The tire pressure sensor is oriented perpendicular to the longitudinal axis. The tire patch is permanently connected to a tire inner tread wall having the longitudinal axis coaxially aligned with a tire radial centerline.
