The invention relates to a steering drive, a steering axle and a land transport means. The steering drive comprises: an electric motor having a motor shaft; a first planetary stage having a first sun gear, a first planet gear, and a first planet carrier; a second planetary stage having a second sun gear, a second planet gear, and a second planet carrier; the steering drive is configured to extend a force flow from the first sun gear to the first planet carrier via the first planet gear, to extend the force flow continuously via the second sun gear and via the second planet gear to the second planet carrier, and to extend the force flow continuously to the steering arm, and wherein the steering drive is configured to drive the steering arm to rotate relative to the second sun gear. The steering arm is mounted so as to be rotatable about a pivot axis. The steering drive according to the invention is characterized in that the steering drive further comprises a spur gear stage, the electric motor is arranged parallel to the pivot axis, and the steering drive is designed to extend a force flow from the motor shaft to the first sun gear via the spur gear stage.
本发明涉及转向驱动器、转向桥和陆路运输工具,转向驱动器包括:具有马达轴的电动马达;具有第一太阳轮、第一行星轮和第一行星架的第一行星级;具有第二太阳轮、第二行星轮和第二行星架的第二行星级;以及转向臂,其中,转向驱动器被构造成用于使力流从第一太阳轮经由第一行星轮延伸至第一行星架,使力流继续经由第二太阳轮并经由第二行星轮延伸至第二行星架,并使力流继续延伸至转向臂,并且其中,转向臂以能围绕摆动轴线转动的方式被支承。根据本发明的转向驱动器的特征在于,转向驱动器还包括圆柱齿轮级,电动马达平行于摆动轴线布置,并且转向驱动器被构造成用于使力流从马达轴经由圆柱齿轮级延伸至第一太阳轮。
