Abstract: A wheel rim including a first wheel rim section having a base and a pair of circumferential support flanges at opposite sides of the base, each of which extends radially outwardly from said base. A second wheel rim section has a base and a pair of circumferential support flanges at opposite sides of the base, each of which curves axially and radially outwardly. The second wheel rim section is sized to fit inside the first wheel rim section with the bases of the respective wheel rim sections in contact engagement. The outer peripheral edges of the flanges of both rim sections meet along the circumference of the wheel rim and are joint together by weldments that extend around the entire circumference of the wheel. The result is a composite wheel rim having an inner contour of a conventional roll-formed wheel rim and an outer, distinct contour. In an alternative embodiment, a composite wheel rim is formed of an extrusion having a cross section corresponding generally to the cross section of the joined two wheel rim sections of the preferred embodiment.

Abstract translation: 一种轮辋，包括具有基部的第一轮辋部分和在所述基部的相对侧处的一对圆周支撑凸缘，每一个从所述基部径向向外延伸。 第二轮辋部分具有基部和在基部的相对侧处的一对圆周支撑凸缘，每个圆周支撑凸缘沿轴向和径向向外弯曲。 第二轮辋部分的尺寸适于装配在第一轮辋部分内部，其中相应的轮辋部分的基部接触接合。 两个边缘部分的凸缘的外围边缘沿着轮缘的圆周相交，并且通过围绕车轮的整个圆周延伸的焊件接合在一起。 结果是具有传统的辊形轮缘和外部不同轮廓的内轮廓的复合轮缘。 在替代实施例中，复合轮缘由具有大致对应于优选实施例的连接的两个轮辋部分的横截面的横截面的挤压件形成。
