Abstract

An improved suspension assembly that may be used as a new or retrofit to existing front and/or rear suspension systems. The assembly may include a multi-layered, press-fit wearband that is received by a modified suspension housing. The wearband is designed to ensure even lubrication, significantly enhancing durability and resistance to harsh conditions. The assembly further comprises a removeable head and retainer for ease of disassembly and reassembly.

Claims (29)

1. A suspension assembly, comprising:

a housing;

a rod configured to be received within the housing;

a removeable head configured to be placed around the rod and adjacent the housing;

an improved wearband configured to be received within the housing and adjacent the rod, the wearband comprising at least a polymer layer, a metal layer, and a sintered layer between the polymer layer and the metal layer;

an improved seal comprising a (plurality of grooves); and

a wiper surrounding an outer portion of the removeable head;

wherein the removeable head is adapted to receive at least one seal.

2. The suspension assembly of claim 1 , wherein the wearband further comprises a metal-polymer blended material.

3. The suspension assembly of claim 1 , wherein the sintered layer is comprised of bronze.

4. The suspension assembly of claim 1 , wherein the at least one seal is an O-ring seal.

5. The suspension assembly of claim 1 , wherein the plurality of grooves are configured to distribute at least one lubricant about both front and back sides of the wearband.

6. The suspension assembly of claim 5 , wherein the at least one lubricant is grease.

7. The suspension assembly of claim 1 , wherein the removeable head is attached to the suspension assembly by a plurality of fasteners for selective removal and reinstallation.

8. The suspension assembly of claim 1 , wherein the rod comprises a taper along only a portion of rod.

9. The suspension assembly of claim 8 , wherein the rod extends beyond one distal end of the housing and terminates with a plate.

10. The suspension assembly of claim 9 , wherein the plate is preferably secured with one or more bolt and washer.

11. A suspension assembly comprising:

a rod;

a removable head;

a housing;

the removeable head configured to be secured to one distal end of the housing;

the rod configured to be inserted into the housing and extend beyond the one distal end of the housing;

a wiper placed about the rod and adjacent the removable head to protect against external contaminants;

a wearband received within housing and in close proximity to an outer circumference of the rod, the wearband comprising a polymer layer, a metal layer, and a sintered layer between the polymer layer and the metal layer;

a plate configured to be secured to a distal end of the rod which extends from the housing; and

at least one seal received by the removeable head for sealing a portion of the suspension assembly.

12. The suspension assembly of claim 11 , wherein the wearband further comprises a metal-polymer blended material.

13. The suspension assembly of claim 11 , wherein the sintered layer is comprised of bronze.
