The invention discloses a trapezoidal steering mechanism of a reverse tricycle or a four-wheel motorcycle. The trapezoidal steering mechanism comprises a steering swing arm, a steering pull rod and wheel shock absorption connecting seats; rotating main pins are arranged in the middles of the two wheel shock absorption connecting seats; the front part of the steering swing arm is hinged with the symmetric center of the steering pull rod; the two ends of the steering pull rod are connected with the front portions of the wheel shock absorption connecting seats through universal couplers; the connecting line between the axes of the two rotating main pins is marked as a, the connecting line between the rotating points of the two universal couplers is marked as b, the connecting line between theaxis of a rotating main pin and a rotating point of a universal coupler on the same side is marked as c, a quadrangle composed of a, c, b and c is of a steering trapezoidal structure, wherein the length of a is smaller than that of b. The trapezoidal steering mechanism has the beneficial effects that the trapezoidal steering mechanism can meet the requirements of the Ackerman corner, the situation that tires are seriously abraded is improved, and controllability and stability in vehicle driving process are improved.

    本发明公开了一种反向三轮车或四轮摩托车的梯形转向机构,包括转向摆臂、转向拉杆、轮子减震连接座,两个所述轮子减震连接座的中部均设置有转动主销;所述转向摆臂前部与所述转向拉杆的对称中心铰接;所述转向拉杆的两端与所述轮子减震连接座的前部通过万向联轴器连接;两个所述转动主销的轴心之间的连线为a,两个所述万向联轴器的旋转点之间的连线为b,同一侧的所述转动主销的轴心到万向联轴器的旋转点连线为c,由a、c、b、c组成的四边形为转向梯形结构,其中a的长度小于b的长度。本发明的有益效果包括:转向机构符合阿克曼转角的要求,改善了轮胎磨损严重的情况,改善了车辆行驶过程中的操控性和稳定性。
