The invention provides a motor tricycle and belongs to the technical field of vehicles. The motor tricycle comprises a frame, a front suspension structure, a rear suspension structure and an adjustingdevice. The adjusting device is arranged to act on a long rod extending out of the rear suspension structure; an adjusting moving block in the adjusting device moves on the long rod under the actionof a driver, a driving lead screw and a guide rod; a stress arm of force of the long rod is adjusted by changing a distance between an adjusting moving block and the rear suspension structure; when the stress arm is reduced, the limiting strength of the long rod on the rear suspension structure can be enhanced; therefore, the inclination amount of the rear suspension structure is reduced and safety accidents such as rollover are prevented; and when the stress arm is increased, the limiting strength of the long rod on the rear suspension structure can be weakened, so that the inclination amountof the rear suspension structure is increased; the vehicle adapts to road conditions, and the running requirements of the vehicle in a high-speed running state and a low-speed running state are effectively considered, so that the safety guarantee is higher, the service life is longer, and riding is more comfortable.

    本发明提供了一种三轮摩托车,属于车辆技术领域。一种三轮摩托车包括车架、前悬挂结构、后悬挂结构以及调节装置;本发明设置调节装置作用于后悬挂结构上伸出的长杆上,调节装置内的调节移动块在驱动器、驱动丝杆以及导向杆的作用下在长杆上移动,使得通过改变调节移动块与后悬挂结构之间的距离来调节长杆的受力力臂,在减小受力力臂时,可增强长杆对后悬挂结构的限制强度,从而减小了后悬挂结构的倾斜量,防止了翻车等安全事故的发生,而在增大受力力臂时,可减弱长杆对后悬挂结构的限制强度,从而增大了后悬挂结构的倾斜量,使车辆自适应路况,有效兼顾了车辆高速和低速两种运行状态下的运行需求,安全保障性更高,使用寿命更长,乘坐更舒适。
