The invention discloses a stepping type logistics trolley based on an Ackerman steering mechanism. According to the invention, a bracket is fixed on the bottom surface of a bottom plate, and hub motors are respectively arranged at two ends of a rear axle at the rear end of the bracket; the front end of the support is fixed to a front axle in the Ackerman steering mechanism, and hub motors are installed at the two ends of a front axle respectively; a stepping motor support and a vertical bearing seat are fixed to one side of the top face of the bottom plate, a rotating shaft of the stepping motor is connected with one end of a coupler, a small bevel gear shaft is connected with the other end of the coupler, and a large bevel gear is embedded in a driving shaft, located on one side of the small bevel gear, in the Ackerman steering mechanism and meshed with the small bevel gear; and the stepping motor transmits torque to the pair of bevel gears and then transmits the torque to a U-shaped groove, and the U-shaped groove rotates around a steering shaft through the steering shaft, so Ackerman steering is achieved. The stepping type logistics trolley is easy to use, tire abrasion and power consumption in a steering process are reduced, high upgradability and universality are achieved, and the stepping type logistics trolley is suitable for various logistics transportation places and can reduce logistics cost.

    本发明公开了一种基于阿克曼转向机构的步进式物流小车。将支架固定在底板底面,支架后端的后桥两端分别装有轮毂电机;支架前端与阿克曼转向机构中的前桥相固定,前桥两端分别装有轮毂电机;步进电机支架和立式轴承座固定在底板顶面的一侧,步进电机的转轴与联轴器的一端连接,小锥齿轮轴与联轴器的另一端连接,大锥齿轮嵌套在阿克曼转向机构中位于小锥齿轮一侧的驱动轴上,并与小锥齿轮啮合。步进电机将转矩传递到一对锥齿轮上,再传递到U型槽上,通过转向轴使U型槽绕着转向轴进行旋转,实现阿克曼转向。本发明使用简单,减少了转向过程中的轮胎磨损和动力消耗,且具有很强的可升级性与通用性,适用于多种物流运输场所,减少物流成本。
