The invention relates to a swing type tricycle. The tricycle body is provided with a tricycle frame, two first wheels movably connected to the front end of the tricycle frame and a second wheel movably connected to the rear end of the tricycle frame, wherein a swing mechanism is arranged between the two first wheels, and when the tricycle body is in an inclined state, the two first wheels are hinged to the tricycle frame; the second connecting rod of the swing mechanism plays a role in supporting and driving the first wheel to deflect, the first connecting rod located above the second connecting rod can restrain the upper portion of the first wheel as well, the first connecting rod and the first wheel are matched to equivalently form a parallelogram structure, deflection is more stable, and angle change is linear; the situation that a large angle is suddenly changed is avoided; besides, due to the design that the first connecting rod and the second connecting rod are restrained on the frame, stress of the two connecting rods can be distributed to the frame to be borne together during deflection, due to the fact that the frame has higher strength, the defect that the strength of the connecting rods is insufficient can be overcome through the design, and the service life of the whole vehicle is prolonged.

    本发明涉及一种摇摆式三轮车,车身具有车架、活动连接在车架前端上的两个第一车轮、活动连接在车架后端上的第二车轮,两个第一车轮之间设置有摇摆机构,在车身处于倾斜状态下,摇摆机构的第二连杆对第一车轮起到的支撑和驱动偏转的作用,位于第二连杆上方的第一连杆同样能对第一车轮的上部进行约束,二者相互配合,相当于形成了平行四边形结构,使得偏转更加的稳定,角度变化线性,不会出现突然改变很大角度的情形;此外,第一连杆和第二连杆约束在车架上的设计,可以将偏转时两个连杆自身的应力分布到车架上来共同承担,由于车架往往具有更高的强度,这样的设计可以弥补连杆强度不足的短板,进而提高提高整车的使用寿命。
