用于重载车辆的轮毂
摘要：
本发明涉及用于重载车辆且用于安装车轮以进行相对旋转的轮毂(100)，其包括具有轴向相对的端部部分和纵向中心轴线(A)的大致圆柱形本体(102)。一对轴承接收孔(124、126)中的每一个在圆柱形本体(102)中在圆柱形本体的相应的轴向相对的端部部分处形成。圆周外壳(182)具有外径(D3)并且围绕所述一对轴承接收孔(124、126)中的一个形成在圆柱形本体(102)上。凸缘(160)在所述一对轴承接收孔(124、126)之间的位置处从圆柱形本体(102)径向向外延伸。圆柱形本体(102)的圆筒部分(104)在凸缘(160)和圆周外壳之间延伸并具有外径(D2)。轮毂(100)通过结合圆筒部分(104)的特定纵向轮廓以及各种尺寸的比率和/或关系而提供足够的强度并使重量最小化。
摘要（英）：

A hub (100) for a heavy-duty vehicle and for mounting a wheel for relative rotation comprises a substantially cylindrical body (102) having axially opposite end portions and a longitudinal central axis (A). Each of a pair of bearing receiving bores (124, 126) is formed in the cylindrical body (102) at a respective axially opposite end portion of the cylindrical body. A circumferential envelope (182) has an outer diameter (D3) and is formed on the cylindrical body (102) about one of the pair of bearing receiving bores (124, 126). A flange (160) extends radially outward from the cylindrical body(102) at a location between the pair of bearing receiving bores (124, 126). A barrel portion (104) of the cylindrical body (102) extends between the flange (160) and the circumferential envelope andhas an outer diameter (D2). The hub (100) provides sufficient strength and minimizes weight by incorporating specific longitudinal profiles and ratios and/or relationships of various dimensions of thebarrel portion (104).
