摘　　要：为了克服现有人力三轮车在行驶时跑偏和转向不灵便的问题,在分析了原有三轮车单轮驱动原理的基础上,提出了采用棘轮机构实现三轮车双轮驱动的设计思想。将三轮车双后轮轮毂内部分别安装上有个内棘轮,当运动从链轮传到后轴上时,安装在两个后轮上的内棘轮与后轴一起转动,带动两个后车轮同时转动,达到同时驱动的目的;当三轮车转弯时,手闸闸住一个后轮,该轮转速变慢或者不动,实现转弯,从而达到前进时不偏转的目的。通过样车实验表明,这种改进不仅行驶安全、可靠、便捷,价格合理,具有较高的推广价值和 市场应用前景。In order to overcome the existing problems that tricycle steers deviated and turns stiffly, we put forward the design idea of realizing double wheel drive of tricycle by ratchet wheel mechanism based on the analysis of the principle of the single wheel drive of the original tricycle. An inner ratchet wheel is respectively arranged on the inner wheels of the two rear wheels of the tricycle. When the movement is transmitted from the sprocket to the rear axle, the inner ratchet wheel installed on the two rear wheels rotates together with the rear axle, and the two rear wheels are driven to rotate at the same time to achieve the purpose of simultaneous drive. When the tricycle turns, the brake makes a rear wheel stop rotating. The wheel turns slow or stops and realizes the turn so as to move forward without deflection. The experiment shows that this kind of improvement is not only safe, reliable, convenient and reasonable, but also has high promotion value and the prospect of market application.
