Abstract

A method of making a wheel support assembly adapted to bolt to an axle of a vehicle for supporting a tire is disclosed herein along with the assembly itself. In accordance with this method, an outer annular rim having an outer annular surface configured to support a tire is provided along with at least one integral piece of sheet metal. The sheet metal is stamp formed into a plurality of spoke arrangements, each of which includes (i) at least two elongated spokes respectively including inner ends and outer ends and (ii) a cross-bar connecting together the inner ends of the spokes and configured to bolt to the axle for connecting the inner ends of the spokes to the axle, whereby to serve as part of a hub of the wheel support assembly. The outer ends of the spokes are connected to the rim. In one embodiment disclosed herein, each spoke arrangement is formed from its own separate and distinct piece of sheet metal. In a second embodiment, all of the spoke arrangements are stamp formed from a single piece of sheet metal.

Claims

1. A wheel support assembly adapted to bolt to an axle of a vehicle for supporting a tire, said assembly comprising:

(a) an outer annular rim having an outer annular surface configured to support a tire and an inner annular surface;

(b) a plurality of spoke arrangements, each of which includes (i) at least two elongated spokes respectively including inner ends and outer ends and (ii) a cross-bar connecting together the inner ends of the spokes and configured to bolt to said axle for connecting the inner ends of said spokes to said axle, whereby said cross-bar serves as part of a hub of said wheel support assembly, all of said spokes and said cross-bars making up the wheel support assembly being integrally stamp formed into a single unit from a single piece of sheet metal, said single unit serving as the only strength imparting structure between said rim and the hub; and

(c) means for connecting the outer ends of said spokes to said rim.

2. An assembly according to claim 1 wherein all of the spokes of said spoke arrangements extend inwardly from said rim along a path which does not coincide with a radius of said rim.

3. An assembly according to claim 2 wherein each spoke arrangement includes only a pair of spokes and wherein each of the spokes of each pair extends inwardly and on opposite sides of a particular radius of said rim.

4. An assembly according to claim 3 wherein each spoke has a generally rectangular cross-section defined by front and back edges and opposing side walls, the latter extending approximately parallel with the axis of said rim, and wherein each side wall is substantially deeper than the edges are wide.

5. An assembly according to claim 1 wherein each of said spoke arrangements includes a single rim connecting member connected to and extending between the two spokes of that arrangement in a direction generally normal to a radius of said rim for connecting to said rim and thereby serving as part of said connecting means.

6. A method of making a wheel support assembly adapted to bolt to an axle of a vehicle for supporting a tire, said method comprising the steps of:

(a) providing an outer annular rim having an outer annular surface configured to support a tire;

(b) providing a single piece of sheet metal and stamp forming from the sheet metal as a single integrally formed unit a plurality of spoke arrangements, each of which is formed to include (i) at least two elongated spokes respectively including inner ends and outer ends and (ii) a cross-bar connecting together the inner ends of the spokes and configured to bolt to said axle for connecting the inner ends of said spokes to said axle, whereby to serve as part of a hub of said wheel support assembly, said plurality of spoke arrangements serving as the only spoke arrangements making up said wheel support arrangement and said single integrally formed unit serving as the only strength imparting structure between said rim and the hub; and

(c) connecting the outer ends of said spokes to said rim.

7. A wheel support assembly adapted to bolt to an axle of a vehicle for supporting a tire, said assembly comprising:

(a) an outer annular rim having an outer annular surface configured to support a tire and an inner annular surface;

(b) a plurality of spoke arrangements, each of which includes (i) at least two elongated spokes respectively including inner ends and outer ends and (ii) a cross-bar connecting together the inner ends of the spokes and configured to bolt to said axle for connecting the inner ends of said spokes to said axle, whereby said cross-bar serves as part of a hub of said wheel support assembly, said spokes and said cross-bar being integrally stamp formed from a piece of sheet metal, wherein each of said spoke arrangements includes a pair of rim connecting flanges respectively connected to the two spokes of that arrangement in a direction generally normal to a radius of said rim for connecting to said rim and thereby serving as part of said connecting means; and

(c) means for connecting the outer ends of said spokes to said rim.
