The invention discloses a chainless bicycle driven by flexible shafts and belongs to the field of traffic tools. The defects that an existing bicycle is strenuous in riding and slow in speed are overcome. The chainless bicycle driven by the flexible shafts comprises footstools fixed to a bicycle body, a rear wheel and a speed change transmission mechanism; a flywheel, a turbine and a worm are mounted on a main shaft of the rear wheel, and the turbine is connected with the worm; the speed change transmission mechanism comprises a first transmission shaft, a second transmission shaft and a third transmission shaft which are mounted in a box body; a first large gear and a first small gear are fixed to the first transmission shaft, a second large gear and a second small gear are fixed to the second transmission shaft, and the second transmission shaft can slide in the box body in the left-right direction; by means of the method that the second transmission shaft is toggled to slide, the first large gear and the second small gear as well as the first small gear and the second large gear are driven to be engaged alternately, and the third transmission shaft is engaged with the second large gear; and transmission shafts of the footstools are connected through the first flexible shaft to drive the first transmission shaft to rotate, and the third transmission shaft is connected through the second flexible shaft to drive the worm to rotate. The chainless bicycle driven by flexible shafts is rapider in riding speed, capable of saving more labor, high in stationarity and accurate and reliable in transmitting.
Description
technical field [0001] The invention belongs to the field of vehicles and relates to bicycles, in particular to a chainless flexible shaft driven bicycle. Background technique [0002] The transmission mode of existing bicycles is mostly the rear wheel drive of chain transmission. The chain often falls off from the chainring when it is slightly loose, and it is easy to get hands dirty when hanging it again. It is a combination of about 660 parts, and the assembly and maintenance are relatively cumbersome. In addition, existing bicycles have the disadvantages of strenuous riding and slow speed. However, other driving methods using front-wheel drive are not very effective due to the limitation of force transmission angle and direction. [0003] In order to solve the above-mentioned defects existing in existing bicycles, the present invention develops a bicycle without a chain and driven by a flexible shaft. Contents of the invention [0004] The invention provides a chain...
