Application March 9, 1936, Serial No. 67,898
10 Claims. (C1. 29—159.03)
This invention relates to the manufacture of thereof, indicated at l3, and by reducing the cir
vehicle wheels and particularly to a method of
manufacturing metallic vehicle wheel bodies.
The object of the invention is to provide an
5 economical method of forming metallic vehicle
Wheel bodies and more speci?cally to provide a
method of forming a plurality of such wheel
bodies from a single blank.
Broadly, the invention consists in the provision
10 of a circular, partially formed blank, separating
this blank circumferentially in a manner to form
a pair of wheel bodies, each having a plurality
of spaced spoke portions, and then further form
ing each of the resulting units to obtain the de
sired final shape. In this manner a large portion
of the various operations are performed upon the
original unit which eventually is divided into two
wheel bodies, thus materially reducing the cost of
the ?nished articles.
20
Other objects and advantages of the invention
will appear from the following description taken
in connection with the accompanying drawings
in which,
Fig. 1 is an edge view of the strip of metal or
25 blank employed,
Fig. 2 is an end View of the ring ?rst formed
from the blank,
Fig. 3 is a sectional view through the ring
shown in Fig. 2 after it has been further partially
30 formed,
Fig. 4 is a sectional View of the circular mem
ber shown in Fig. 3 with the line of separation
indicated thereon,
v
Fig. 5 is a side View of one of the units after
35 the separation as indicated in Fig. 4 has taken
place,
Fig. 6 is a side elevational view of the unit
shown in Fig. 5 after it has been further formed
to obtain the desired shape,
40
Fig. '7 is a sectional View taken substantially on
the line ‘l—'! of Fig. 6,
Fig. 8 is a fragmentary elevational view of a
metallic vehicle wheel embodying the Wheel body
formed by the present method, and
Fig. 9 is a fragmentary vertical sectional View
of the wheel shown in Fig. 8.
Referring noW to the drawings, reference nu
meral l0 indicates a strip of metal which is cut
to the correct length and width and coiled by
5 O any suitable means into a circular ring H and
the free ends thereof welded or otherwise secured
together as at l2. The ring H is then rolled or
5
otherwise suitably Worked to produce the shape
shown in Fig. 3. Preferably this is accomplished
by enlarging the circumference of the midportion
cumference of the sides thereof, as indicated at
Hi. When thus formed, the ring has sloping side
Walls i4 provided with central openings 86. If
desired, the plain ring H or the shaped blank
shown in Fig. 3 may be preformed by suitable
forging methods.
In dividing the blank shown in Fig. 3 to pro
vide two separate wheel bodies, it is circumfer
entially separated about the peripheral or mid 10
portion I3 along a substantially serpentine path,
as shown at H (Fig. 4), as by shearing Without
the removal of any metal, by punching spaced
openings and then shearing between such open
ings or by a punching operation to form a con 15
tinuous slot. The straight shearing is preferred.
In this manner a pair of identical wheel body
portions 2i and 22 are produced which include
the peripheral spoke portions 98 and it.
Each of the wheel bodies 2! and 22 is next 20
further formed by any suitable means such as
by punches and dies or by bending and swaging
to obtain any desired ?nal shape. As here shown
(Figs. 6 and '7) the ?nal shape is produced by
bending the spoke portions i8 and I9 radially
and outwardly to provide radially extending
spokes having axially extending rim seats 23 at
their outer extremities. The side portions I4 are
bent inwardly to form radial bolting on ?anges
[6a and axially inclined naves 16a.
30
The preferred manner of assembling the wheel
bodies in a completed wheel is shown in Figs. 8
and 9. As there shown wheel body 22 is provided
with suitable openings in the axially extending
rim seats 23 at the outer ends of spokes IQ for
the reception of rivets 25 by means of which a
conventional form of rim 24 is permanently at
tached to the wheel body. The bolting on ?ange
I 6a is also provided with a series of stud bolt
receiving openings about the central hub open 40
ing I6.
The wheel body 22 is adapted to be detachably
secured to a radial ?ange 28 of a wheel hub 29
by means of the stud bolts 21 and clamping nut
assemblies 3! in a conventional manner.
The
stud bolts 2'! are rigidly mounted in hub flange
‘28 and the wheel body 22 is adapted to be mount
ed on the hub With studs 2? projecting through
the openings in bolting on flange Mia‘. The wheel
body is detachably locked in this position by the
clamping nuts 35.
Stud bolts 27 may also serve
to secure a brake drum 32 to hub 29 as shown in
Fig. 9.
It will thus be seen that a method of manu
facturing metallic vehicle wheel bodies has been
2
2,069,068
' provided whereby the preliminary forming opera—
tions are performed upon a single unit which in
turn is divided into a plurality of units, thus
materially reducing the total cost of manufac~
ture. Various modi?cations in the method as
herein described will be obvious to those skilled
in the art, but it is to be understood that the
invention is to be limited only by the scope of the
appended claims.
