Abstract

A clip for assembling a module comprising a flange head bolt, and a member that receives the flange head bolt. The clip has an inner washer and an outer washer that are joined by a bridging portion. The outer washer has a retainer tub that engages the flange of the flange head bolt. The clip may be referred to as a banjo clip when it is used with a banjo block that connects a brake line to a brake caliper.

Claims

1. A banjo clip assembly, comprising:

a bolt having a head that is formed with a flange;

a member having a threaded opening for receiving the bolt;

a banjo clip comprising an inner washer portion and an outer washer portion that are joined by a bridging portion, the outer washer having a crimp tab formed thereon; and

wherein the bolt is inserted through the outer washer, the member, and the inner washer, with the crimp tab securing the banjo clip to the bolt by engaging the flange and thereby securing the bolt, member and banjo clip together.

2. The banjo clip assembly of claim 1 wherein the banjo clip holds the bolt together with the member with the bolt being rotatable relative to the member and the banjo clip.

3. The banjo clip assembly of claim 1 wherein the banjo clip creates a fluid seal between at least one of the washers and the member when the bolt is tightened against the at least one washer and the member.

4. The banjo clip assembly of claim 3 wherein the fluid seal is a high pressure hydraulic fluid seal.

5. The banjo clip assembly of claim 3 wherein the fluid seal is a pneumatic seal.

6. The banjo clip assembly of claim 1 wherein the banjo clip is formed from a material consisting essentially of one of the following:

copper;

steel;

aluminum;

bronze;

or

polymeric material.

7. The banjo clip assembly of claim 1 wherein the member is a brake caliper banjo block.

8. The banjo clip assembly of claim 1 wherein the member is a component of a fluid delivery system.

9. The banjo clip assembly of claim 1 wherein the member is a disc brake component part and the flange head bolt is a flow bolt that provides a fluid passageway through the disc brake component part and the inner and outer washers form a seal with the member when the flange head bolt is tightened against a disc brake assembly.

10. A fluid coupling for connecting a brake line to a brake caliper of a vehicle brake system, comprising:

a flow bolt comprising a bolt having a fluid passageway connecting the brake line to the brake caliper, the flow bolt having a head that is formed with a flange;

a banjo block having a brake line receptacle, a threaded opening, and an internal passageway formed in the threaded opening that encircles the flow bolt wherein brake fluid may flow from the brake line through the banjo block and the flow bolt to the brake caliper;

a banjo clip comprising an inner washer portion and an outer washer II portion that are joined by a bridging portion, the outer washer having a crimp retainer formed thereon; and

wherein the flow bolt is inserted through the outer washer, the banjo block, and the inner washer, with the crimp retainer being formed to secure the banjo clip to the flow bolt by engaging the flange and thereby securing the flow bolt, banjo block and banjo clip together as a module.

11. The fluid coupling of claim 10 wherein the flow bolt has a threaded shaft extending from the head to a distal end, a central bore extending coaxially through a portion of the shaft portion, and a radially extending bore connecting the central bore to a fluid passage defined in the banjo block.

12. The fluid coupling of claim 10 wherein the banjo block has a tubing receptacle having a fluid port, a threaded opening for receiving the flow bolt, and an annular internal passageway that is in fluid flow communication with the fluid port.

13. The fluid coupling of claim 12 wherein the flow bolt has a threaded shaft extending from the head to a distal end, a central bore extending coaxially through a portion of the shaft portion, and a radially extending bore connecting the central bore to the internal passageway defined in the banjo block.

14. The fluid coupling of claim 10 wherein the banjo clip holds the flow bolt together with the banjo block with the bolt being rotatable relative to the banjo block and the banjo clip.

15. The fluid coupling of claim 10 wherein the banjo clip creates a fluid seal between at least one of the washers and the banjo block when the flow bolt is tightened against the at least one washer and the banjo block.

16. A clip assembly, comprising:

a bolt having a head that is formed with a flange;

a fluid coupling having a threaded opening for receiving the bolt;

a clip comprising an inner washer portion and an outer washer portion that are joined by a bridging portion, the outer washer having a crimp tab formed thereon; and

wherein the bolt is inserted through the outer washer, the fluid coupling, and the inner washer, with the crimp tab engaging the flange to loosely secure the clip to the bolt thereby securing the bolt, fluid coupling and clip together.

17. The clip assembly of claim 16 wherein the clip holds the bolt together with the fluid coupling with the bolt being rotatable relative to the fluid coupling and the clip.

18. The clip assembly of claim 16 wherein the clip creates a fluid seal between at least one of the washers and the fluid coupling when the bolt is tightened against the at least one washer and the fluid coupling.

19. The clip assembly of claim 16 wherein the fluid coupling is a disc brake component part and the bolt has a fluid passageway that permits fluid flow through the disc brake component part and the inner and outer washers form a seal with the fluid coupling when the bolt is tightened against a disc brake assembly.

20. The clip assembly of claim 16 wherein the fluid coupling is a component of a fluid delivery system.
