Problems solved by technology
[0002] The current bicycle with crank cranks is not on the tangent line of the crank crank because the pedaling force is not on the tangent of the crank crank, which will cause more or less loss of the force of pedaling the crank crank, and because the force cannot be output at some points, this makes the present Cranking crutches can't do more work for the bicycle
But when going uphill and the resistance is large, we have to output a large force on the pedal, otherwise the other foot will not be able to produce work, which will cause most of the force to become useless work, which is also the current bicycle crank unavoidable energy loss

Embodiment Construction
[0009] The present invention will be further described below in conjunction with accompanying drawing:
[0010] figure 1 It is the general structure of the present invention. When the left pedal is stepped on, the pendulum gear 2 that meshes with the upper end will drive the right rack and the right pedal that are meshed with it to generate an upward movement, and at the same time, the ratchet 5 on the left lower rack will transmit power to the On the disc teeth. When the right pedal is stepped on, the pendulum gear 2 will drive the left rack and the upward movement generated by the left pedal, and the ratchet 8 on the left lower rack will transmit the power to the faceplate teeth through the four connecting gears during counterclockwise rotation. In this way, the downward movement of the left and right foot pedals clearly transfers the power to the rear wheel through the faceplate teeth, chain, and rear axle ratchet in the reciprocating motion of the rack.

The invention discloses a bicycle consisting of racks, ratchets and half gears. When a left pedal and a left upper rack 1 produce downward motion, a right rack 4 and a right pedal 6 are to be driven by a swing gear 2 to produce upward motion, and the ratchet 5 on a left lower rack 7 transfers power to disk teeth of a shaft of the ratchet during clockwise rotation. When the right pedal 6 is stepped to move downwards, the swing gear 2 drives the left rack to produce upward motion, and the ratchet 8 on the left lower rack transfers power to the disk teeth through four linkage gears during anticlockwise rotation. Thus, left and right feet step downwards to do work to enable the bicycle to produce motion in work doing processes of the ratchet 5 and the ratchet 8 respectively.
Description
Technical field: [0001] The invention relates to a gear rack reciprocatingly driving a ratchet wheel so that the stepping power is directly changed from a linear motion to a circular motion. technical background: [0002] The current bicycle with crank cranks is not on the tangent line of the crank crank because the pedaling force is not on the tangent of the crank crank, which will cause more or less loss of the force of pedaling the crank crank, and because the force cannot be output at some points, this makes the present The crank crutch movement cannot give the bicycle more work. But when going uphill and the resistance is large, we have to output a large force on the pedal, otherwise the other foot will not be able to produce work, which will cause most of the force to become useless work, which is also the current bicycle crank Inevitable energy loss. Invention content: [0003] The purpose of the present invention is to provide a transmission device with a novel s...
