Abstract
Abstract A wheel, especially a disk wheel has six components, namely, two mirror-setrical hub sections, a wheel rim, two bending resistant wheel disks and a thrust and/or shear resistant body enclosed by the rim, by the two hub sections, and by the two wheel disks whereby metal components and fiber composite material components are bonded to one another to form the wheel. The materials of these components are selected for three purposes, to simplify the construction, to optimize the strength characteristics of the wheel, and to greatly increase the wheel's ability to dampen vibrations. The hub sections and rim are made of metal, the disks are made of fiber compound material and the enclosed body is made of metal or fiber compound material all held together by an adhesive bond. The hub sections have radially extending flanges which intermesh with the radially inner edge of the wheel disks in a multilayer fashion. The thrust and/or shear resistant body has preferably a honeycomb type structure.

Claim 1
Independent Claim
348 words
In a wheel having a hub (1) with a rotational axis (A), a wheel rim (3) and bending resistant means (2) operatively interconnecting said wheel rim (3) to said hub (1), the improvement comprising two hub sections (1 1 ; 1 2 ) which are substantially mirror symmetrical relative to a central radial plane through the wheel, each hub section (1 1 ; 1 2 ) comprising respective substantially radially extending flange means (4 1 ; 4 2 ) located at an axially outer end of the respective hub section (1 1 ; 1 2 ), said bending resistant means (2) comprising first and second cover members (8 1 ; 8 2 ) for transmitting substantially radially extending forces from said wheel rim (3) into said hub (4), said bending resistant means further comprising body means (9) rigidly enclosed between said first and second cover members, first adhesive bonding means operatively connecting said flange means (4 1 ; 4 2 ) to the respective first and second cover members (8 1 ; 8 2 ), second adhesive bonding means operatively connecting said first and second cover disks (8 1 ; 8 2 ) to said wheel rim (3), third adhesive bonding means securing said body means (9) to said first and second cover members (8 1 ; 8 2 ), to said hub sections (1 1 ; 1 2 ), and to said wheel rim (3), said body means comprising a structure which is thrust resistant in the direction of said rotational axis for transmitting substantially axially extending forces into said hub, wherein said radially extending flange means of said hub sections have a substantially triangular cross-section with substantially axially facing surfaces (6 1 ; 6 2 ; 5 1 ; 5 2 ) and a circumferential edge (7 1 ; 7 2 ) pointing substantially radially outwardly, and wherein each of said first and second cover members has two flaps (10 1 ; 11 1 ; 10 2 ; 11 2 ) reaching radially inwardly in a forked manner for hugging said substantially axially facing flange surfaces.
Claim 2
Dependent Claim
348 words
In a wheel having a hub (1) with a rotational axis (A), a wheel rim (3) and bending resistant means (2) operatively interconnecting said wheel rim (3) to said hub (1), the improvement comprising two hub sections (1 1 ; 1 2 ) which are substantially mirror symmetrical relative to a central radial plane through the wheel, each hub section (1 1 ; 1 2 ) comprising respective substantially radially extending flange means (4 1 ; 4 2 ) located at an axially outer end of the respective hub section (1 1 ; 1 2 ), said bending resistant means (2) comprising first and second cover members (8 1 ; 8 2 ) for transmitting substantially radially extending forces from said wheel rim (3) into said hub (4), said bending resistant means further comprising body means (9) rigidly enclosed between said first and second cover members, first adhesive bonding means operatively connecting said flange means (4 1 ; 4 2 ) to the respective first and second cover members (8 1 ; 8 2 ), second adhesive bonding means operatively connecting said first and second cover disks (8 1 ; 8 2 ) to said wheel rim (3), third adhesive bonding means securing said body means (9) to said first and second cover members (8 1 ; 8 2 ), to said hub sections (1 1 ; 1 2 ), and to said wheel rim (3), said body means comprising a structure which is thrust resistant in the direction of said rotational axis for transmitting substantially axially extending forces into said hub, wherein said radially extending flange means of said hub sections have a substantially triangular cross-section with substantially axially facing surfaces (6 1 ; 6 2 ; 5 1 ; 5 2 ) and a circumferential edge (7 1 ; 7 2 ) pointing substantially radially outwardly, and wherein each of said first and second cover members has two flaps (10 1 ; 11 1 ; 10 2 ; 11 2 ) reaching radially inwardly in a forked manner for hugging said substantially axially facing flange surfaces.
Claim 3
Dependent Claim
60 words
The wheel of claim 1, wherein said hub sections including said flange means and said rim are made of metal, wherein said first and second cover disks are ring disks made of fiber composite material, and wherein said body means is made of a material which is shear resistant and bending resistant, substantially in the direction of said rotational axis.
Claim 4
Dependent Claim
17 words
