The invention provides a foldable tandem type double-person double-drive tricycle capable of being quickly disassembled and assembled, which comprises a front tricycle, a rear tricycle and couplings, the front tricycle comprises two front wheels and a tricycle frame arranged on the two front wheels, a front tricycle seat tube is arranged in the middle of the tricycle frame, the rear tricycle comprises a camber beam and a rear wheel, the front tricycle seat tube is fixedly connected with the camber beam through the couplings, and the rear wheel is fixedly connected with the camber beam through the couplings. The front wheel is connected with the front saddle tube, the rear wheel is connected with the camber beam, the coupling comprises a front axle, a frame and a rear axle, the frame is connected with the front saddle tube through the front axle, and the frame is connected with the camber beam through the rear axle. The coupling can swing up and down and left and right, it is guaranteed that when the bicycle goes uphill and downhill and passes through a gully or a bumpy road surface, a certain wheel can be prevented from being suspended or stressed unevenly, and the three wheels can well touch the ground; and the rear bicycle can rotate freely during turning, so that the flexibility of the bicycle set is guaranteed.

    本发明提供一种可快速拆装可折叠的串联式双人双驱三轮自行车,包括前车、后车、联轴节,前车包括两个前车轮及设于两个前车轮上的车架,所述车架中部设有前车座管,后车包括弯梁、后车轮,前车座管通过联轴节与弯梁固定连接,后车轮与弯梁连接,联轴节包括前轴、框架、后轴,框架通过前轴与所述前车座管连接,框架通过后轴与所述弯梁连接,较现有技术相比,本发明具有以下优点:本发明通过联轴节将前后车串联在一起,形成双人双驱的三轮自行车,联轴节可上下、左右摆动,保障了自行车在上下坡、通过沟壑或坑洼路面时能够避免某个轮子悬空或受力不均,三个轮子均能很好的着地;转弯时后车可自由转动,保障了自行车组的灵活性。
