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.

Claims

1. A tire pressure sensing system, comprising:

a tire patch having a first face and an oppositely directed second face;

a sensor mount positioned on the first face of the tire patch oppositely facing with respect to the second face, the sensor mount including opposed first and second bias clip members;

a tire pressure sensor releasably retained to the sensor mount by the bias clip members; and

the tire patch second face is fixed to an inner tread wall of a tire having the longitudinal axis of the tire patch coaxially aligned with a radial centerline of the tire.

2. The tire pressure sensing system of claim 1, wherein:

the sensor mount clip members are oriented perpendicular with respect to the longitudinal axis of the tire patch and are elastically deflected when releasably engaging the tire pressure sensor; and

the sensor mount is fixed in direct contact with the first face by at least one fastener extending through the tire patch and the sensor mount.

3. The tire pressure sensing system of claim 2, wherein the at least one fastener includes first and second fasteners each having a fastener head positioned proximate to the second face.

4. The tire pressure sensing system of claim 3, further including:

a rectangular shaped plate directly fixed to the second face having longer sides oriented perpendicular to a longitudinal axis of the tire patch; and

the first and second fasteners extending through the tire patch and the plate having the fastener head of each in direct contact with the plate thereby fixing the plate to the second face and the sensor mount to the first face.

5. The tire pressure sensing system of claim 1, wherein the body longitudinal axis of the tire pressure sensor is oriented perpendicular to a tire radial centerline and perpendicular to a rotational direction of the tire centering a mass of the tire pressure sensor on the tire radial centerline, the sensor mount and the tire patch aligned with the radial centerline thereby balancing rotational forces generated by the tire pressure sensing system.

6. The tire pressure sensing system of claim 5, wherein the tire pressure sensor has a length greater than a width, such that the orientation of the tire pressure sensor perpendicular to the tire radial centerline and perpendicular to the rotational direction minimizes a tire pressure sensor width oriented in the rotational direction thereby minimizing a force acting to dislodge the tire pressure sensor from the tire tread wall during deflection of the tread wall.

7. The tire pressure sensing system of claim 1, further including a layer of adhesive applied to the tire patch second face to fix the tire patch to the inner tread wall of the tire and wherein the tire pressure sensor is oriented perpendicular with respect to the longitudinal axis of the tire patch when the tire patch is fixed to the inner tread wall.

8. The tire pressure sensing system of claim 1, further including a first sensor fastener extending through the sensor mount proximate to the first bias clip member, and a second sensor fastener extending through the sensor mount proximate to the second bias clip member, the first and second sensor fasteners releasably fastening the tire pressure sensor to the sensor mount.

9. The tire pressure sensing system of claim 1, wherein the tire patch has a length which is greater than a width and wherein the longitudinal axis is parallel to sides of the tire patch having a side length equal to the tire patch length.

10. The tire pressure sensing system of claim 1, further including first and second plate fasteners extending through the tire patch and the sensor mount, wherein the first and second plate fasteners are equally spaced with respect to the longitudinal axis of the tire patch and centered both radially and diagonally with respect to a bonding face of the tire patch.

11. A tire pressure sensing system, comprising:

a tire patch having a first face and an oppositely directed second face;

a plate fixed to the second face and oriented perpendicular with respect to a longitudinal axis of the tire patch;

a sensor mount positioned on the first face of the tire patch oppositely facing with respect to the plate, the sensor mount including opposed first and second bias clip members;

the tire patch fixed to an inner tread wall of a tire having the longitudinal axis of the tire patch coaxially aligned with a radial centerline of the tire.

12. The tire pressure sensing system of claim 11, wherein the tire pressure sensor includes a first engagement end having an aperture for receiving a first fastener, and a second engagement end having an aperture for receiving a second fastener.

13. The tire pressure sensing system of claim 12, wherein the sensor mount includes a first gap centrally disposed in the first bias clip member having a width selected to permit contact between the first bias clip member with the first engagement end of the tire pressure sensor when the first fastener is received through the first gap.

14. The tire pressure sensing system of claim 13, wherein the sensor mount includes a second gap centrally disposed in the second bias clip member having a width selected to permit contact between the second bias clip member with the second engagement end of the tire pressure sensor when the second fastener is received through the second gap.

15. The tire pressure sensing system of claim 12, wherein the tire pressure sensor includes a first end wall extending past a raised height of the first engagement end, and a second end wall defining a mirror image configuration of the first end wall extending past a raised height of the second engagement end, the first and second end walls when in contact with an edge of the sensor mount prevent further sliding motion of the tire pressure sensor into the sensor mount.

16. The tire pressure sensing system of claim 12, wherein the first and second bias clip members are formed to create first and second partial cavities sized to slidably receive the first and second engagement ends when the tire pressure sensor is coupled with the sensor mount by a lateral sliding motion of the tire pressure sensor.

17. A tire pressure sensing system, comprising:

a tire patch having opposed first and second faces and including;

a first layer of an elastically flexible material and including the second face; and

a second layer of an adhesive applied to the first layer and creating the first face;
