Light metal wheel
A wheel, particularly a light metal wheel, for motor vehicles, essentially consists of a spoke wheel center ( 20 ) and a rim ( 10 ). In order to reduce weight and increase the bending strength, which is of great significance in regard to contact with curbstones and potholes, profile segment ( 31 ) in the form of half-shell units, which forms a continuous hollow chamber ( 41 ) in the direction of the circumference, at least in sections, are provided in the area of an external base of the rim ( 14 ).
1. A wheel, for motor vehicles, comprising:
spoke wheel portion ( 20 ) and a wheel rim ( 10 );
wherein the wheel rim ( 10 ) further comprises an internal bead seat ( 16 ) and an external bead seat ( 14 ) which makes a transition into an internal flange ( 18 ) and an external flange ( 12 );
wherein at least one profile segment ( 31 , 32 , 33 , 34 , 35 , 36 , 37 ) which continuously forms at least one hollow chamber ( 41 , 42 , 43 , 44 , 45 , 46 , 47 ) in the direction of the circumference, at least in sections, is provided proximate the internal bead seat ( 16 ) and/or of the external bead seat ( 14 );
and wherein the at least one profile segment ( 31 , 32 , 33 , 34 , 35 , 36 , 37 ) is initially configured as a substantially radially extending flange ( 30 ) emanating from the wheel rim between the inner and outer flanges, and having a radially outwardly disposed free edge ( 51 ), which radially extending flange ( 30 ) is reformed to curve back upon the wheel rim with the free edge ( 51 ) rejoined to the wheel rim, to define a hollow space therebetween,
and further wherein the substantially radially extending flange ( 30 ) emanating from the wheel rim between the inner and outer flanges is bent axially outwardly toward a face of the wheel in a single step to define a hollow chamber.
2. A wheel, for motor vehicles, comprising:
spoke wheel portion ( 20 ) and a wheel rim ( 10 );
wherein the wheel rim ( 10 ) further comprises an internal bead seat ( 16 ) and an external bead seat ( 14 ) which makes a transition into an internal flange ( 18 ) and an external flange ( 12 );
wherein at least one profile segment ( 31 , 32 , 33 , 34 , 35 , 36 , 37 ) which continuously forms at least one hollow chamber ( 41 , 42 , 43 , 44 , 45 , 46 , 47 ) in the direction of the circumference, at least in sections, is provided proximate the internal bead seat ( 16 ) and/or of the external bead seat ( 14 );
and wherein the at least one profile segment ( 31 , 32 , 33 , 34 , 35 , 36 , 37 ) is initially configured as a substantially radially extending flange ( 30 ) emanating from the wheel rim between the inner and outer flanges, and having a radially outwardly disposed free edge ( 51 ), which radially extending flange ( 30 ) is reformed to curve back upon the wheel rim with the free edge ( 51 ) rejoined to the wheel rim, to define a hollow space therebetween,
wherein the internal flange ( 18 ) and the external flange ( 12 ) each extend radially outwardly of the at least one hollow chamber.
