ONE-PIECE DI SK WHEEL Filed Aug. 5. 1932 ZISheets-Shet 1 Patented Jan. 1, 19 35 1,986,698 ONE-PIECE msx WHEEL Moritz Winkler, Bochum, Germany, assignor to the-firm Verelnigte Stahlwerke Aktlengelellschaft, Dusseldorf, Germany UNITED STATES Application August 5, 1932, Serial No. 627,670 In Germany March 10, 19s:
1 Claim. (01. 301-64) One-piece disk wheels, which have an undulating shape in an axial direction, were hitherto so shaped that both the depth of the undulations and the curve of the undulated shape always differed according to the different radial distance irom the-centre of the disk, so that in themeduction of such disks in forgeable material, and particularly during the pressing of the previously rolled level raw-disks into undulated shape, dies had to be used, the production of which required much time and was very costly on account of the constantly diiierent depth of the undulations and the changing curve of the unclulated shape.
15 This disadvantage is to be eliminated according to the present invention in that the depth of the undulations or corrugations of one-piece disk wheels or other similar pieces, in which the diskshaped part between thehub and the rim is undu- 20 lated or corrugated in a radial direction or is bent alternately in the one or the opposite direction, is the same at all places, and in that the curve of the undulated shape is the same at all places, the length of the waves, which increases 25 as they are closer to the periphery,-being obtained by intercalating sections defined by. straight lines 2' which become greater as they get closer to the" periphery. 7
Due to this new shape of disk the production becomes far less expensive and therefore the cost of the finished product is reduced. I
The drawings illustrate, by way of example, one form of application oi the invention.
Figurel is a side view of a one-piece disk wheel the disk-shaped part of which has, besides its s-shaped undulation in a radial direction, undulations or corrugations in an axial direction as well.
Figure 2 is a developed section through the circular line lI-'-II of Figure l, and
Figure 8 is a developed section through the circular line III-III of Figure 1.
Fig. 4 is a radial section through half of a wheel and the correspond shalves of the dies.
Figure a section taken along the line 5-5 of The two cross sections show that the wave depth 1 is the same on all the radial corrugations 1 or undulations at different distances from the centre, and that the curve of the flanks thereof"- trom the point 2 to the point 8 is exactly the same as the curve of the flanks from point 4 to point 6. The width of the-sections between the flanks which increases as it gets closer to the periphery is obtained by intercalating level sections deflned by straight lines 5 which become wider as they get closer to the periphery. In other words these level sections in the form of elevations or depressions gradually increase in width with an increasing radius.
Figure4 shows on an enlarged scale a section through a part of a disk having such undulations or corrugations, with the dies required for the production of the'undulations. With the aid of the upper die 7 and the lower die 8, the disk as shown by the dotted lines 9, is pressed into an s-shape, that is, first towards one side and then towards the other, as the shapes 10 and 11 show Figure 4. Figure 4 also shows that the depth 1 oi the circumferential or concentric undulations or corrugations is the same at all places.
The gist of the invention will not be affected by using, instead of the wheels (shown in the constructional forms) wherein the wheel rim is secured-to the felloe by shrinkage. so-called solid wheels of disk-shape according to the present invention, that is to say, wheels wherein the wheel rim is providedon the felloe at the outset.
What I claim and desire to secure by letters Patent isz- A one-piece disk wheel comprising in combination radially and circumferentially extending corrugatlons oi the disk-shaped part of the wheel between the hub and the rim, the radial corrugations having a uniform depth over their entire lengths and the circumferential corrugations having an s-shaped cross-section.
