The invention relates to the technical field of electro-tricycles, and concretely relates to a steering mechanism of an electric tricycle. The steering mechanism comprises a tricycle underframe, a first rotating support is arranged at the front end of the tricycle underframe, a rotating shaft is fixed to the front end of the tricycle underframe, a first chain wheel is arranged above the first rotating support, and a front fork is arranged below the first rotating support, a second rotating support is arranged at the corner of the tricycle underframe, a second chain wheel is mounted, the firstchain wheel is connected with the second chain wheel, a first gear is arranged above the second chain wheel, a third rotating support is further arranged at the corner of the vehicle underframe, a steering handle is arranged above the third rotating support, a second gear is arranged above the steering handle, a fourth rotating support is arranged at the rear end of the vehicle underframe, a rearaxle assembly is fixed below the fourth rotating support, and a pull ring is arranged on the rear axle assembly and is connected with a driving rope through the steering handle. By means of chain transmission and gear transmission, when the front wheel of the electric tricycle is operated to steer, the rear wheels are driven to steer slightly in the direction opposite to the steering direction ofthe front wheels, the turning radius of the tricycle body is reduced, and the controllability of the electric tricycle is improved.

    本发明涉及电动三轮车技术领域,具体涉及一种电动三轮车转向机构,包括车底架,其前端设置有旋转支承一并固定有转轴,所述旋转支承一上方设置链轮一,下方设置前叉,所述车底架的拐角处设置有旋转支承二并安装链轮二,所述链轮一和链轮二连接,所述链轮二上方设置有齿轮一,所述车底架的拐角处还设置有旋转支承三并在上方设置有转向柄,所述转向柄上方设置有齿轮二,所述车底架的后端设置有旋转支承四并在下方固定后桥总成,所述后桥总成上设置有拉环并与转向柄通过传动索连接,本发明通过链传动和齿轮传动,实现了在操作电动三轮车前轮转向的同时,带动后轮向前轮转向的反方向小幅转向,减小了车身的转弯半径,提高了电动三轮车的操控性。
