Abstract
Hub centric truck wheel cap apparatus including a cup shaped cap having a cylindrical wall configured with radially through windows. A set of spacer rings having lugs of different radial depths are provided for mating with the cap and projecting through such windows to form spacers in the annulus between selected wheels of different center bore diameters and a centering shoulder on a truck hub.
Claims23
Hub centric truck wheel cap and spacer apparatus engaging an axially inwardly facing retainer surface in an annulus formed between a center bore of a truck wheel having an axially inwardly facing retainer surface and a truck hub and comprising:
- an axially projecting cylindrical cup shaped hub cap formed on its axial inner extremity with at least one radially outwardly turned cap retainer flange for engaging behind said retainer surface, said cap further including radial clearance windows spaced circumferentially thereabout;
- and
- a spacer ring constructed to be removably received in concentric relationship with said cap, said ring formed on its outer diameter with a retainer for retaining said ring in axial spaced relationship relative to said wheel, and spacer lugs spaced circumferentially therearound for receipt in said annulus for projecting radially through said windows and formed with respective radially outwardly facing bearing facets to engage with said axially inwardly facing retainer surface in said bore.
A method of mounting a truck hub having a center bore of a predetermined diameter to a hub having a centering shoulder of a selected diameter smaller than said predetermined diameter and including:
- selecting a hub cap for covering said hub and configured to project inwardly through said bore and formed with at least one radially outwardly projecting retainer flange;
- selecting a retainer ring configured to be mated with said cap and having radially projecting splines configured to be received in said windows positioned in the annulus formed between said shoulder and said bore to center a wheel on said shoulder;
- mating said selected spacer ring with said cap;
- and
- assembling said cap on said wheel by pushing said cap through said bore.
Hub centric truck wheel spacer ring for mating with a cylindrical cup shaped hub cap, said hub cap being formed on its axial inner extremity with at least one radially outwardly turned cap retainer flange for engaging behind a chamfer and having radial clearance windows spaced circumferentially thereabout to engage in an annulus formed between the center bore of a truck wheel having an axially inwardly facing chamfer and the hub of said truck wheel and comprising:
- a spacer ring constructed to be removably received in concentric relationship with said cap, said ring formed on its axially outer end with a retainer for retaining said ring in axial spaced relationship relative to said wheels, and spacer lugs spaced circumferentially therearound for receipt in said annulus for projecting radially through said windows and formed with respective radially outwardly facing bearing facets to engage with said axially inwardly facing retainer surface in said bore.
Hub centric truck wheel cap and spacer apparatus comprising:
- a truck wheel formed with a center bore for receipt of a truck hub to cooperate in forming an annulus and configured with an axially inwardly facing chamfer circumscribing said bore and formed with an axially inwardly facing retainer surface;
- an axially projecting cylindrical cup shaped hub cap formed on its axial inner extremity with a radially outwardly turned cap retainer flange for engaging behind said chamfer, said cap further including radial clearance windows spaced circumferentially thereabout;
- and
- an axially elongated spacer ring constructed to be removably received in concentric relationship with said cap, said ring formed on its axially inner end with a retainer for retaining said ring in axial spaced relationship relative to said wheel and spacer lugs spaced circumferentially therearound for receipt in said annulus for projecting radially through said windows and formed with respective radially outwardly facing bearing facets to engage with said axially inwardly facing retainer surface.
