Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
187 words
A wheel for motor vehicles, comprising a wheel rim with a drop center of reduced diameter, a wheel dish having a central portion with bolt apertures positioned in the zone of the drop center and coextensive peripheral portions directed axially outwardly and radially outwardly from the central portion, respectively, the radially outwardly extendiNg portion being in proximity to the periphery of the wheel rim and the axially outwardly extending portion being in proximity to the drop center so as to form a generally radially outwardly directed annular passage therebetween, and connecting ribs extending from the wheel dish to the rim, said ribs being secured to the rim and to the dish and having a width substantially equal to the axial length of said annular passage, said ribs being formed as thin blades which function as a radial blower which feeds air from the inside of the wheel toward the outside of the wheel through said annular passage with the air inlet being in the zone of reduced diameter of the rim and the air outlet being in the zone of the larger diameter periphery of the rim.
Claim 2
Dependent Claim
187 words

Claim 3
Dependent Claim
32 words
A wheel according to claim 1, characterized in that the connecting ribs, as viewed in front view, occupy at most about 30 percent of the annular surface between wheel dish and rim.
Claim 4
Dependent Claim
25 words
A wheel according to claim 1, characterized in that the number of connecting ribs is divisible by the number of fastening screws of the wheel.
Claim 5
Dependent Claim
32 words
A wheel according to claim 3, characterized in that the connecting ribs, as viewed in front view, occupy at most about 30 percent of the annular surface between wheel dish and rim.
