The invention discloses a single-axle steerable power bogie which comprises a lifting unit, a mandrel, a single-axle bogie and a driven steering center plate. The mandrel is fixedly connected with thelifting unit; the single-axle bogie makes contact with the lifting unit and is driven by the lifting unit to move in the vertical direction; and the driven steering center plate is rotationally connected with the mandrel and is fixedly connected with the single-axle bogie, so that the single-axle bogie can rotate around the mandrel. When the single-axle bogie is lifted/lowered in different statesby utilizing the lifting unit (a parallelogram mechanism can be selected), the main framework body of the single-axle bogie is always kept in a horizontal state, so that structural support is provided for passive steering function design of the single-axle bogie; and meanwhile, the power bogie is designed into a single-axle form, so that the weight and the cost of the device can be effectively reduced.

    本发明公开了一种单轮轴可转向的动力转向架,包括升降单元、心轴、单轮轴转向架和被动转向心盘;所述心轴与所述升降单元固定相连;所述单轮轴转向架与升降单元接触,由所述升降单元驱动在竖直方向运动;被动转向心盘与所述心轴转动相连,且与所述单轮轴转向架固定相连,实现单轮轴转向架可绕所述心轴转动。本发明利用升降单元(可以选择平行四边形机构)实现单轮轴转向架提升/下放不同状态时,其主构架体始终保持水平状态,这为单轮轴动力转向架的被动转向功能设计提供了结构支撑;同时,动力转向架设计为单轮轴形式,能有效降低装置的重量及成本。
