The invention discloses a cast steering axle of a biconical bearing steering mechanism. The cast steering axle comprises a steering axle body and steering knuckle hub assemblies, wherein the knuckle hub assemblies are arranged on the two sides of the steering axle body respectively. The steering knuckle hub assemblies are fixedly arranged on the steering axle body through steering mechanisms respectively; the steering mechanisms comprise master pins; the steering knuckle hub assemblies and the master pins are fixedly installed through first screws; tapered roller bearings and framework oil seals are arranged in an upper pin seat and a lower pin seat of the steering axle body; the upper parts and the lower parts of the master pins are respectively arranged on the tapered roller bearings; bearing check rings are installed between the tapered roller bearings and the steering knuckle hub assemblies; O-shaped sealing rings are installed between the bearing check rings and the steering knuckle hub assemblies; a bearing pressing plate is installed at the lower end of the tapered roller bearing located at a lower portion; and the bearing pressing plate is fixed to the lower pin seat of thesteering axle body through a second screw. According to the cast steering axle of the double conical bearing steering mechanism, the reliability and durability of the steering axle can be greatly improved.

    本发明公开了一种双圆锥轴承转向机构的铸造转向桥,包括转向桥体、转向节轮毂总成,转向节轮毂总成分别设置在转向桥体两侧,转向节轮毂总成分别通过转向机构固装在转向桥体上,转向机构包括主销,转向节轮毂总成和主销通过螺钉一固装,转向桥体的上销座和下销座内均设有圆锥滚子轴承和骨架油封,主销的上部和下部分别安装在圆锥滚子轴承上,圆锥滚子轴承与转向节轮毂总成之间安装有轴承挡圈,轴承挡圈与转向节轮毂总成之间安装有O型密封圈,位于下方的圆锥滚子轴承下端安装有轴承压板,轴承压板通过螺钉二固定在转向桥体的下销座上。该双圆锥轴承转向机构的铸造转向桥可以大幅提升转向桥的可靠性和耐久性。
