Problems solved by technology
[0002] In the existing tandem bicycles, when riding, two people need to ride hard at the same time, and need basically the same coordination. Riding is relatively labor-intensive, the riding speed is slow, and the driving speed of both feet is limited, resulting in a low riding speed. Generally, it is below 20 km / h. Therefore, people often switch to riding electric bicycles or motorcycles in order to pursue speed. However, the batteries of electric bicycles will cause environmental pollution, and motorcycles need to consume fuel, a non-renewable resource.

The invention discloses a tandem bicycle achieving speed increasing, and relates to a vehicle. The tandem bicycle comprises a frame, a front driving mechanism, a rear driving mechanism and a rear wheel mechanism; the front driving mechanism comprises a first gear, a second gear, a front driving axle and a front trampling bar; the rear driving mechanism comprises a third gear, a fourth gear, a sprocket wheel and a rear trampling bar; the first gear and the third gear are arranged on the same side of the frame, the second gear and the fourth gear are arranged on the same side of the frame, a speed-increasing transmission mechanism is arranged between the first gear and the third gear, a same speed-increasing transmission mechanism is arranged between the second gear and the fourth gear, each speed-increasing transmission mechanism comprises an axle, bevel gears are fixedly connected to the two ends of the axle respectively, the bevel gears at the two ends of the axle are meshed with the first gear and the third gear respectively, and the bevel gears at the two ends of the axle on the other side are meshed with the second gear and the fourth gear respectively; a flywheel is fixedly connected to a rear rotating shaft, and the flywheel is in transmission connection with the sprocket wheel through a chain. The tandem bicycle is simple in structure and easy and rapid to ride.
Description
technical field [0001] The invention relates to a vehicle, in particular to the technical field of manufacturing a tandem bicycle. Background technique [0002] In the existing tandem bicycles, when riding, two people need to ride hard at the same time, and need basically the same coordination. Riding is relatively labor-intensive, the riding speed is slow, and the driving speed of both feet is limited, resulting in a low riding speed. Generally, it is below 20 km / h. Therefore, people often switch to riding electric bicycles or motorcycles in order to pursue speed. However, the batteries of electric bicycles will cause environmental pollution, and motorcycles need to consume fuel, a non-renewable resource. Contents of the invention [0003] The invention provides a self-speeding double bicycle with simple structure, easy and fast riding. [0004] The present invention comprises a vehicle frame, a front driving mechanism, a rear driving mechanism, and a rear wheel mechanis...
