The invention discloses a motor tricycle, which mainly adopts a cross axle suspension with a simple structure and an axle with a simple structure to reduce the manufacturing cost, and then changes the connection mode between a carriage and a frame, and the main body of the cross axle suspension is a cross axle bracket with two axes crossed vertically and horizontally, namely a guide frame. Driving wheels are installed at the two ends of a transverse shaft, the two ends of a longitudinal shaft are connected with a frame through a front hinge and a rear hinge, the rear hinge is a floating hinge, the transverse shaft plays a role of an axle, the longitudinal shaft plays a role of a push rod, and a guide frame replaces an original guide role completed by five parts, namely the axle, the two push rods and the five steel plate springs in two sets. Wherein the elastic rigidity of the elastic element is changed by adopting a method of increasing or decreasing springs in parallel so as to adapt to the change of load, and the problem that comfort and safety cannot be considered at the same time is solved. A power system on the axle axis is changed from original four-point support to three-point support. And the carriage and the frame are horizontally and rotatably connected in the horizontal plane, so that the control sensitivity during turning of the vehicle can be improved.

    本发明公开了一种机动三轮车,主要是采用结构简单的十字轴悬架和结构简单的车桥,以降低造价,其次是改变了车厢与车架之间的连接方式,十字轴悬架的主体是一个两轴线纵横相交或交叉的十字轴支架,称导向架,其横轴两端安装驱动轮,纵轴两端由前、后两个铰连接车架,其中后铰为浮动铰,横轴起车桥的作用,纵轴起推杆的作用,一个导向架取代了原来由五个零部件完成的导向作用,即车桥、两个推杆、两组钢板弹簧五个。其中弹性元件采用并联增减弹簧的方法改变其弹性刚度,以适应荷载的改变,解决了舒适性与安全性两者不能兼顾的问题。车桥轴线上的动力系统由原来的四点支承改变为三点支承。车厢与车架在水平面内的连接为水平转动连接,可提高车辆转弯时的操控灵敏性。
