Abstract
Description
The present invention relates to an automatic transmission bicycle, and more particularly, to convert a reciprocating motion of a pedal into a reciprocating circular motion of a planetary gear, and the reciprocating circular motion of a planetary gear rotates a ring gear to generate an output while generating an output. The present invention relates to an automatic transmission bicycle driven by a pedal and a handle capable of shifting a rotational speed of an output shaft by using a centrifugal force increase and decrease according to a change of speed, and at the same time generating an output even with a forward and backward reciprocating movement of the handle.
Currently used bicycle has the trouble of manually shifting, and when the position of the pedal passes the highest point and the lowest point during the rotational movement of the crank, the pedaling force is weakened, and only the foot is driven so that the upper body movement cannot be performed. have.
The present invention is designed to solve the problems of the existing bicycle as described above, is automatically shifted according to the pendulum speed of the crank, driven by the up and down movement of the pedal to avoid the weakening of the pedal force according to the rotation angle In addition, the present invention relates to a pedal-driven automatic transmission bicycle capable of generating an output even with a reciprocating movement of the handlebar.
In order to achieve the object as described above, the present invention is a
When the pedal moves up and down by the pedal force, the crank pendulum movement around the
As the speed of pedal movement increases, the pendulum movement of the crank also increases, and the connecting
In addition, by adjusting the tension of the
In addition, when the steering wheel is moved back and forth along with pedaling, the reciprocating pivot movement can increase the output by adding driving force to the planetary gear lever connected by the handle and connecting rod.
The present invention is automatically shifted according to the speed is more convenient than the conventional bicycle, driven by the up and down reciprocating movement of the pedal to improve the driving force, it can also be driven using the arm to exercise the upper body and inconvenient lower body Can also be used.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.
Referring to FIG. 1, the embodiment of the present invention has a

Referring to FIG. 6, the
1, 2, and 3, the planetary gear lever is attached to the planetary gear (118, 122) and the planetary gear is engaged with the ring gear (120, 121) can move in contact with the internal combustion of the ring gear, When the planetary gear lever pendulum moves, the planetary gear moves in a reciprocating circular motion along the ring gear inner edge about the
If the planetary gear can rotate freely in both directions when the planetary gear is reciprocating, the planetary gear moves in contact with the inner surface of the meshed ring gear and rotates freely and cannot drive the ring gear, but the planetary gear is influenced by the one-way bearing. Because only one direction of rotation rotates, one of the reciprocating circular arcs rotates idling and the other direction generates the rotation of the ring gear. However, since the two planetary gears can rotate only in different directions, one of the reciprocating circular motions drives the
1 and 4, one of the two ring gears is meshed with the
In this embodiment, the gears are used, but the outer edges of the output gear, the auxiliary gear and the ring gear are sprockets instead of gears and connected by chains, or the sprockets and the arm sprockets (the sprockets and the arm sprockets are covered with discs on both sides of the teeth of the mating sprockets are separated). Sprockets that are not made).
Looking at the shift principle of the present automatic transmission in detail, when the driver first presses down one pedal to start, the other pedal is lifted up by the action of the
Referring to Figure 5 to examine the spring adjustment principle in detail, the
When starting from the flat, the spring adjustment lever should be in the middle, downhill on the high stage, uphill on the lower stage. While driving, the speed is automatically changed. If you want to change the speed ratio, you can change the speed ratio by operating the spring adjustment lever.
If you stop driving the pedal or steering wheel while driving, the crank and planetary gear lever will stop moving, but the bicycle will roll with inertia and the planetary gear will idle because of the bearing.
The

If the driver doesn't want to drive the steering wheel at all, he removes the connecting rod from the bicycle and lowers the connecting lever to fix the handle shaft to the head tube.
