Abstract
Abstract A motor vehicle wheel, particularly a motorcycle wheel, comprising two identical, contiguous, co-axial, complementary light metal pressings or stampings fixed to a hub member, each forming half of a rim bed for a tire. The two mating wheel pressings provide a star-like wheel spider having closed hollow main and auxiliary spokes. The invention also relates to a method for the manufacture of such a vehicle wheel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
161 words
A vehicle wheel having a rim bed, said wheel comprising two substantially identical, contiguous light metal pressings mounted on a hub member, each pressing forming a half of the rim bed, wherein: (a) the hub member has cylindrical centering surfaces for the pressings, (b) the two pressings are provided on their opposing inside surfaces with a layer of solderable material and are soldered both to the hub member and to one another at their contiguous surfaces, (c) the two contiguous pressings form a spoke wheel center having spokes constituted of closed hollow sections and (d) the spokes comprise substantially tangential main spokes and short radial auxiliary spokes, the main spokes extending inwardly from the rim bed in a direction approximately tangentially relative to the hub member and, at their innermost locations relative to the hub member, intersecting another main spoke, and the auxiliary spokes connecting radially the main spokes, at the innermost locations of the main spokes, to the hub member.
Claim 2
Dependent Claim
161 words
A vehicle wheel having a rim bed, said wheel comprising two substantially identical, contiguous light metal pressings mounted on a hub member, each pressing forming a half of the rim bed, wherein: (a) the hub member has cylindrical centering surfaces for the pressings, (b) the two pressings are provided on their opposing inside surfaces with a layer of solderable material and are soldered both to the hub member and to one another at their contiguous surfaces, (c) the two contiguous pressings form a spoke wheel center having spokes constituted of closed hollow sections and (d) the spokes comprise substantially tangential main spokes and short radial auxiliary spokes, the main spokes extending inwardly from the rim bed in a direction approximately tangentially relative to the hub member and, at their innermost locations relative to the hub member, intersecting another main spoke, and the auxiliary spokes connecting radially the main spokes, at the innermost locations of the main spokes, to the hub member.
Claim 3
Dependent Claim
36 words
A wheel according to claim 1, wherein the spoke sections of the two pressings have an approximately oval cross-section with a larger dimension in the axial direction which is progressively reduced radially outwardly along the spokes.
Claim 4
Dependent Claim
33 words
A wheel according to claim 1, wherein the hub member is a casting and has holes for assembly screws in two spaced flanges for mounting the pressings and for connecting other wheel parts.
Claim 5
Dependent Claim
130 words
A wheel according to claim 1, wherein the hub member comprises an externally smooth tubular element on which are mounted two pressings each having outwardly directed flanges contiguous with the hub member, wherein in an annular space between the pressings adjacent the hub member, which annular space includes angularly spaced auxiliary spokes, the pressings are reinforced by steel reinforcing rings whose shape corresponds to the inside shape of the pressings in their spoke-free sections of the annular space and which have inwardly directed abutting flanges contiguous with the hub member, the pressings being affixed to the hub member and to one reinforcing ring and each reinforcing ring being affixed to the hub member, and wherein mounting holes are located in the area of the pressings reinforced by the reinforcing rings.
Claim 6
Dependent Claim
15 words
A wheel according to claim 4, wherein the hub member is formed of light metal.
Claim 7
Dependent Claim
30 words
A wheel according to claim 1, having a cavity between the pressings and depressions in the rim bed, wherein the cavity and depressions are filled with a cellular hard foam.
Claim 8
Dependent Claim
15 words
A wheel according to claim 6, wherein the cellular hard foam comprises hard polyurethane foam.
Claim 9
Dependent Claim
31 words
A method for the manufacture of the wheel of claim 1, wherein heat treatment of the pressings and their soldering to one another is performed simultaneously in a single annealing process.
Claim 10
Dependent Claim
17 words
A wheel according to claim 1, wherein each main spoke intersects at least two other main spokes.
