The main body includes a front frame a front wheel, a rear frame, two rotation devices, two rear wheels, two cranks, and two connecting members. The rotation devices are connected by the transmission link through connection of the connecting members so that the rotation devices are rotatable synchronously and the rear wheels are movable with the rotation devices synchronously. Thus, the two rear wheels are turned synchronously by connection of the transmission link so as to turn and change the travel direction of the pedalling vehicle exactly.
Claims18
A pedalling vehicle, comprising:
- a main body including a front frame having a first end provided with a front wheel and a pedal unit, a rear frame having a first end adjustably and detachably connected with a second end of the front frame, two opposite rotation devices each rotatably mounted on a second end of the rear frame, two rear wheels each mounted on the respective rotation device to rotate with the respective rotation device, two cranks each having a first end mounted on the respective rotation device to rotate the respective rotation device to turn the respective rear wheel, and two connecting members each having a first end mounted on the respective rotation device to rotate with the respective rotation device;
- two opposite control handles each pivotally mounted on and movable relative to the rear frame of the main body;
- two opposite drive links each having a first end connected to and driven by the respective control handle and a second end connected to a second end of the respective crank of the main body to drive the respective crank, wherein each of the two control handles drives the respective drive link which drives the respective crank which rotates the respective rotation device which turns the respective rear wheel;
- and
- a transmission link having two opposite ends each connected to a second end of the respective connecting member of the main body so that the rotation devices are rotatable synchronously and the rear wheels are able to turn with the respective rotation devices synchronously.
