The invention relates to a self-steering axle assembly having an axle with a central tube having a longitudinal central axis. The kingpin is connected with an end portion of the axle. The steering knuckle is connected with the main pin. The knuckle includes a torque plate section. A first arm of the knuckle extends from one side of the torque plate section and receives a first end portion of the kingpin. The second arm extends from the torque plate section in the same direction as the first arm. The second arm receives the second end portion of the kingpin. The spindle is friction welded to the torque plate section and has a longitudinal central axis. The torque plate section has at least one surface on the torque plate section that extends substantially perpendicular to the longitudinal central axis of the spindle. The tool engages the surface during friction welding of the spindle to the torque plate section. The relative positions of the axle, the spindle, and the kingpin enable the air disc brake actuator to avoid contact with components of the heavy-duty vehicle during steering and to avoid contact with the ground and debris.
本发明涉及自转向车桥组件,其具有车桥,该车桥具有中心管,该中心管具有纵向中心轴线。主销与车桥的端部部分连接。转向节与主销连接。转向节包括扭矩板部段。转向节的第一臂从扭矩板部段的一侧延伸并接纳主销的第一端部部分。第二臂从扭矩板部段在与第一臂相同的方向上延伸。第二臂接纳主销的第二端部部分。主轴摩擦焊接到扭矩板部段并具有纵向中心轴线。扭矩板部段在扭矩板部段上具有至少一个表面,该表面大致垂直于主轴的纵向中心轴线延伸。在将主轴摩擦焊接到扭矩板部段期间,工具与该表面接合。车桥、主轴和主销的相对位置使空气盘式制动器致动器能够避免在转向过程中与重载车辆的部件接触并且能够避免与地面和碎屑接触。
