Description of reference numerals: the bicycle comprises a bicycle frame 1, a rear wheel 11, a handlebar 12, a front wheel 13, a seat tube 14, a seat cushion 15, a transmission shaft 2, a flywheel 21, a power device 3, a driving chain wheel 31, a driving shaft 32, a pedal 33, a connecting rod 34 and a chain 35.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description.
As shown in fig. 1-4, a unilateral driving device for a tricycle comprises a frame 1, a transmission shaft 2, two rear wheels 11 and a power device 3, wherein the transmission shaft 2 is arranged on the frame 1, the transmission shaft 2 is linked with one of the rear wheels 11, the other rear wheel 11 can freely rotate at the end part of the transmission shaft 2, a flywheel 21 is arranged on the transmission shaft 2, and the power device 3 is connected with the flywheel 21 to rotate.
The transmission shaft 2 is fixedly connected with the right rear wheel 11 and is rotatably connected with the left rear wheel 11.
