Description

Leg and Arm Powered Bicycle with Automatic Transmission

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 a patent application (application number: 10-2011-0121924) of the present inventors pending patent application converting the pendulum motion belonging to the automatic continuously variable transmission to the reciprocating circular motion of the planetary gear to apply the principle of driving the ring gear to the bicycle will be.

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 pedal 127 is attached to one end of the cranks 128, 129 reciprocating, the other end is connected to the planetary gear lever 114 with a connecting pin 115 The planetary gears 118 and 122 are connected to one end of the planetary gear lever, and the planetary gears mesh with the ring gears 120 and 121. In addition, the connecting rod 111 is attached to the middle portion of the handle shaft 102 capable of the front and rear movement and the other end is connected to the end of the planetary gear with a pin.

When the pedal moves up and down by the pedal force, the crank pendulum movement around the crankshaft 131, when the crank pendulum movement, the planetary gear lever connected to the crank also pendulum movement, the pendulum movement of the planetary gear lever The circular motion of the planetary gears inserted into the one-way bearings 117 and 123, which are converted into reciprocating circular motions of the planetary gears 118 and 122 attached to the end of the lever, and which can be rotated in only one direction, are ring gears 120 and 121. ) To generate the output.

As the speed of pedal movement increases, the pendulum movement of the crank also increases, and the connecting pin 115 connecting the crank and the planetary gear lever is separated from the crankshaft 131 by a centrifugal force and the amplitude increases. The larger the amplitude of the connecting pin, the larger the amplitude of the planetary gear shaft and the longer the stroke distance of the reciprocating arc motion of the planetary gear connected to one end of the planetary gear lever. As the stroke length increases, the rotation speed of the ring gear meshed with the planetary gear increases beyond the increase of the crank pendulum speed and the speed ratio becomes large.

In addition, by adjusting the tension of the adjustment spring 130 for pulling the connecting pin in the crankshaft direction, it is possible to change the transmission ratio as the driver intends.

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 pedal 127 at the front end of the cranks 128 and 129. When the pedal is pressed, the left and right cranks 129 and 128 perform pendulum movement about the same crank shaft 131. 6, the left and right cranks are connected to the linkage crank 132 so that the left pedal is lowered and the right pedal is configured to ascend.

1 and 2, the rear of the crank is connected to the planetary gear lever 114 configured to rotate around the center axis 119 of the ring gears 120 and 121, respectively. Rail grooves 133 and 135 are connected to the connecting pins 115 penetrating both rail grooves, so the pendulum movement of the crank generates the pendulum movement of the planetary gear lever.

Referring to FIG. 6, the weights 116 are integrally attached to the left and right connecting pins 115 so that when the pendulum is accelerated, the centrifugal force increases, freely along the crank groove 135 and the planetary gear lever groove 133. As the movable connecting pin 115 moves away from the crankshaft 131 and the connecting pin moves away from the crankshaft, the amplitude of the connecting pin increases and thus the amplitude of the pendulum motion of the planetary gear lever increases. This increased amplitude becomes a source of increasing speed ratio.

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 ring gear shaft 119. The planetary gears are coupled to the planetary gear shafts 136 and 137 and one-way bearings 117 and 123, respectively. The two one-way bearings are used in opposite directions of rotation to each other.

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 first gear 120 and the second the second gear 121 in rotations of different directions. .

1 and 4, one of the two ring gears is meshed with the output gear 124 and the other with the auxiliary gear 125, and the output gear and the auxiliary gear are also meshed with each other, so that the two ring gears rotate in different directions. And rotate. That is, when one of the ring gears rotates in the forward direction, the other ring gears interlock and rotate at the same speed in the negative direction. In this case, the planetary gears rotate in a constant direction because the planetary gears alternate between the driving circular motion and the idle circular motion during the reciprocating circular motion.

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 interlock crank 132. When the left and right pedals are alternated, the crank pendulum moves and the connected planetary gear lever also moves. At first, when the pendulum speed of crank is slow, the connecting pin is located close to the crankshaft 131 due to the tension of the spring 130, so the amplitude is small and the stroke distance of the reciprocating circular motion of the planetary gear is also short. Produces an output The faster the pedal is pressed, the faster the pendulum movement of the crank and the greater the centrifugal force generated on the weight 116. The connecting pin 115 moves away from the crankshaft 131, the amplitude of the planetary gear lever becomes larger, and the planetary gear reciprocating arc. The stroke length is increased, and in addition to the increased reciprocating speed, the stroke length is increased to obtain the gear ratio of the high gear. If the driver wants to change the shift ratio arbitrarily, the tension control force of the spring 130 may be adjusted by pulling or pushing the spring adjustment lever 103 attached to the handle to obtain the desired speed ratio.

Referring to Figure 5 to examine the spring adjustment principle in detail, the weight 116 is connected to the centrifugal spring 138 and the centripetal spring 130 mounted at both ends in the crank rail groove 135, the other of the centripetal spring The end is connected to the spring adjustment cable 104, the spring adjustment cable is connected to the spring adjustment lever 103 attached to the handle, the centrifugal or centripetal direction of the crankshaft by adjusting the spring adjustment lever Can be changed. The centrifugal spring 138 is slightly stronger than the centripetal spring 130, and when the spring adjustment lever is placed at the highest end, the weight 116 moves as much as possible in the centrifugal spring direction.

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 handle shaft 102 is configured to reciprocate back and forth around the connecting shaft 108. The connecting rod 111 is connected to the middle connecting shaft 106 of the handle shaft, and the other end of the connecting rod is a planetary gear. It is configured to be pinned at one end of the lever, so the reciprocating pivot movement of the handle shaft independently generates the output of the bicycle or assists the driving of the pedal movement.

1 and 8, when it is desired to stop the forward and backward reciprocation of the handle shaft 102, when the connecting lever 105 is pushed down, the handle shaft is fixed to the head tube 109 by the fastener 107, and at the same time the connecting rod The 111 is separated from the connecting shaft 106 and moves along the connecting rod guide 110 capable of pivoting around the connecting shaft, thereby freely moving as the planetary gear lever 114 moves. If you want to drive the handle shaft again, stop the pedal movement for a while to stop the movement of the connecting rod, pull up the connecting lever 105, release the handle shaft, align the connecting shaft 106 to the end of the connecting rod, and fully secure the connecting lever upward. The rod is fixed to the connecting shaft and moves together with the handle shaft to transmit the driving force of the handle shaft to the planetary gear lever.

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.
