摘要： A steering wheel has a rim section, a hub section and a pair of spokes connecting the hub section to the rim section. The hub section includes a hub member of a metal including a cylindrical portion defining therein an axial bore for a steering shaft and an integral flange. The spokes include spoke cores made of a length of metal rod including a central arcuate bend extending along the junction between the cylindrical portion and the flange of the hub member, a pair of radially extending arms or opposite end portions and rising portions interconnecting the end portions and the central arcuate bend. The flange is formed therein with a pair of generally diametrically opposed notches with which the rising portions of the metal rod are engaged to form torque-transmitting connections. The hub member and the metal rod are rigidly secured together by a molded plastic layer surrounding the outer periphery of the hub member and the central arcuate bend and the rising portions of the metal rod.
摘要翻译：方向盘具有轮辋部分，轮毂部分和将轮毂部分连接到轮辋部分的一对辐条。轮毂部分包括一个金属的轮毂件，它包括一个在其中限定转向轴的轴向孔和整体法兰的圆柱形部分。轮辐包括由一定长度的金属棒制成的轮辐芯，包括沿圆柱形部分和轮毂部件的凸缘之间的接合部延伸的中心弓形弯曲部，一对径向延伸的臂或相对的端部，以及将端部和中央弧形弯曲。法兰在其中形成有一对大致直径相对的凹口，金属杆的上升部分通过该凹槽接合以形成扭矩传递连接。轮毂构件和金属杆通过围绕轮毂构件的外周边的模制塑料层和中心弓形弯曲部以及金属杆的上升部分刚性地固定在一起。
