Abstract

An air maintenance tire system component protector is provided. An air maintenance tire system includes at least one connecting tube extending between and being in fluid communication with an annular air tube and a valve housing. The protector includes a first end disposed proximate the connection of the at least one connecting tube to the annular tube, and a second end disposed proximate the valve housing. A mid-portion of the protector is disposed between the first and second ends. The protector covers an outboard surface of the at least one connecting tube and the valve housing, and includes means for engaging the at least one connecting tube to secure the position of the tube.

First claim

What is claimed is:

1. A protector for components of an air maintenance tire system, the components of the air maintenance tire system including an annular air tube being mounted to a tire, a mounting member being secured to a sidewall of the tire and connected to the annular air tube, and at least one flexible connecting tube extending between the mounting member and a valve housing to enable fluid communication between the annular air tube and the valve housing, the protector comprising:
a first end disposed proximate a connection of the at least one connecting tube to the mounting member and being secured to the mounting member;
a second end disposed proximate the valve housing and being secured to the valve housing, whereby the protector covers at least an outboard surface of the at least one connecting tube for a length of the connecting tube extending between the mounting member and the valve housing; and
a mid-portion disposed between the first end and the second end, the protector being formed with a taper extending from the first end to the mid-portion, and with a taper extending from the second end to the mid-portion.

2. The protector of claim 1 , wherein the first end of the protector is curved axially inboardly.

3. The protector of claim 2 , wherein the first end of the protector is secured to the mounting member by a mechanical fastener.

4. The protector of claim 2 , wherein the first end of the protector includes an elastomeric material that engages the mounting member.

5. The protector of claim 2 , wherein the first end of the protector includes a mounting flange that seats on a respective fitting at the mounting member.

6. The protector of claim 1 , wherein an opening is formed in the second end of the protector for receiving a bolt of the valve housing, a lip is formed on an inner circumference of the opening, and a nut engages the lip.

7. The protector of claim 1 , wherein the second end of the protector includes a valve mounting flange that seats on a boss formed on the valve housing.

8. The protector of claim 1 , wherein the mid-portion includes a flexible member.

9. The protector of claim 8 , wherein the flexible member is a discrete elastomeric member.

10. The protector of claim 8 , wherein the flexible member is an integrated flexible feature.

11. The protector of claim 1 , further comprising at least one slot formed in a radially inward surface of the first end of the protector to engage the at least one connecting tube.

12. The protector of claim 1 , further comprising at least one connector attached to an inboard surface of the protector to engage the at least one connecting tube.

13. A protector for components of an air maintenance tire system, the components of the air maintenance tire system including an annular air tube being mounted to a tire, a mounting member being secured to a sidewall of the tire and connected to the annular air tube, and a pair of flexible connecting tubes, a first one of the pair of the connecting tubes extending between the mounting member and a valve housing and being in fluid communication with a first end of the annular air tube and the valve housing, and a second one of the pair of the connecting tubes extending between the mounting member and a valve housing and being in fluid communication with a second end of the annular air tube and the valve housing, the protector comprising:
a first end disposed proximate a connection of each one of the pair of the connecting tubes to the mounting member and being secured to the mounting member; and
a second end disposed proximate the valve housing and being secured to the valve housing, whereby the protector covers at least an outboard surface of each one of the pair of the connecting tubes for a respective length of each connecting tube extending between the mounting member and the valve housing.

14. The protector of claim 13 , wherein the protector includes a first half that defines an internal cavity that receives the first one of the pair of the connecting tubes, and the protector includes a second half that defines an internal cavity that receives the second one of the pair of the connecting tubes.

15. The protector of claim 14 , further comprising a plurality of bridges that connect the first half and the second half, whereby the protector forms an integral unit.

16. The protector of claim 13 , wherein the first end of the protector is formed with a mounting flange, and the mounting flange seats on a respective fitting at the mounting member to secure the first end of the protector to the mounting member.

17. The protector of claim 13 , wherein the second end of the protector is formed with a mounting flange, and the mounting flange seats on a respective valve housing boss to secure the second end of the protector to the valve housing.

18. A protector for components of an air maintenance tire system, the components of the air maintenance tire system including an annular air tube being mounted to a tire, a mounting member being secured to a sidewall of the tire and connected to the annular air tube, and at least one flexible connecting tube extending between the mounting member and a valve housing to enable fluid communication between the annular air tube and the valve housing, the protector comprising:
a first end disposed proximate a connection of the at least one connecting tube to the mounting member and being secured to the mounting member; and
a second end disposed proximate the valve housing and being secured to the valve housing, whereby the protector covers at least an outboard surface of the at least one connecting tube for a length of the connecting tube extending between the mounting member and the valve housing, and wherein the protector surrounds from about two hundred and seventy degrees to about three hundred and sixty degrees of a circumference of the at least one connecting tube.

19. The protector of claim 18 , wherein the first end of the protector is formed with a mounting flange, and the mounting flange seats on a respective fitting at the mounting member to secure the first end of the protector to the mounting member.

20. The protector of claim 18 , wherein the second end of the protector is formed with a mounting flange, and the mounting flange seats on a respective valve housing boss to secure the second end of the protector to the valve housing.
