Disclosed is an auxiliary speed-shifting device that assists a main speed-shifting device of a bicycle to facilitate the shifting of gears, even when gears are engaged. The auxiliary speed-shifting device includes installation holes (18), a press receiver, and a rotator. The installation holes (18) are arranged in a pole control ring (15) to connect the inside of the installation holes (18) to the outside thereof. The press receiver is disposed in the installation hole (18) to move in and out of the pole control ring (15). The rotator is disposed outside the pole control ring (15), and has spline recesses (27, 27a, 27b) in the inner surface thereof. As the rotator rotates, surfaces defining the spline recesses (27, 27a, 27b) press the press receiver to release the engagement of poles (12, 13). Accordingly, since the main speed-shifting device can be operated with a device such as an electric switch that requires a very small amount of force, components for shifting speed can be significantly improved.

Transmission for motor and controlling device thereof
A transmission is adapted to have a deceleration structure while generating an output in the same direction as when a motive power is rotated forwardly when the motive power is rotated reversely. The transmission includes a motor, an output cover, fixed shafts, and a transmission. The transmission is selectively connected according to the rotational direction of the driving shaft. The transmission provides a constant speed output in the forward direction since the driving shaft and the output cover are directly connected to each other when the driving shaft is rotated forwardly, but provides a decelerated output in the forward direction since a reduction planetary gear is geared between the driving shaft and the output cover when the driving shaft is rotated reversely.
Disclosure is a one-way transmission for a motor having a structure capable of changing a speed while obtaining an output in the direction same as that of the forward rotation when the motor is rotated in a reverse direction. The one-way transmission for a motor according to the present invention includes a hub shell secured onto a fixed shaft extended in both directions such that the hub shell is rotatable, a built-in motor having a driving shaft disposed in the hub shell, and a transmission unit interposed between the driving shaft and the hub shell to output, with a speed change, the driving force of the built-in motor to the hub shell in one direction. The transmission unit includes a first sun gear and a second sun gear coupled with each other with a gap on an outer circumference of the driving shaft and restrained by a one-way clutch such that the first sun gear and the second sun gear have directionalities opposite from each other, a first planetary gear engaged with the first sun gear, and a second planetary gear engaged with the second sun gear and with the first planetary gear and the hub shell.
The present invention concerns a speed controller for a motor which prevents interference from reverse input. For a known speed controller for a motor, a drive shaft of the motor outputs a constant forward rotation speed to an output cover and it outputs different speeds to the output cover in reverse rotation thereof. According to the present invention, when two driven members are coupled with a drive shaft at a constant speed and different speeds, at least one driven member of two members is not driven at any positions, so reverse power input from the output cover does not interfere with the other driven member. A key protrudes from the outer circumference of the drive shaft and is combined with a pole-mounting ring, wherein a key groove is formed. The width of the key groove is larger than the key. Lower parts of a constant-speed pole and a different-speed pole which are differently oriented to each other are extended downward and mounted in the pole-mounting ring. As the pole-mounting ring is friction-fixed by a separate frictional pin, one or both poles may be moved by the key to a horizontal position according to the rotational direction of the drive shaft. Furthermore, the circumference of the drive shaft is polygonal and whereon a constant-speed ball and a different-speed ball are distanced from each other and are combined with a ball-mounting ring. The top and bottom of the ball-mounting ring protrude. As the ball-mounting ring is friction-fixed by a separate frictional pin, one or both balls may be separated from the circumference of the drive shaft according to the rotational direction of the drive shaft.
The present invention relates to a bi-directional pedaling exercise bicycle including: a first shaft axially coupled to a pair of arm-exercising pedals; a first shaft belt pulley fitted around the first shaft and having an upper limb part belt output pulley mounted thereon so as to be connected to a load part while being restrained to the first shaft by means of a one-way clutch bearing CB; a second shaft engaged with the first shaft by means of gears; and a second shaft belt pulley fitted around the second shaft and connected to the first shaft belt pulley by means of a normal belt NB while being restrained to the second shaft by means of a one-way clutch bearing CB.

The transmission includes: a motor having a driving shaft; an output cover adapted to surround the outside of the motor and rotated by receiving a rotational force of the motor; fixed shafts adapted to extend toward both sides of the output cover; and a transmission formed between the driving shaft and the output cover. The transmission is selectively connected according to the rotational direction of the driving shaft to thereby provide an output at a constant speed or a reduced speed only in a predetermined direction. The transmission provides a constant speed output in the forward direction since the driving shaft and the output cover are directly connected to each other when the driving shaft is rotated forwardly, but provides a decelerated output in the forward direction since a reduction planetary gear is geared between the driving shaft and the output cover when the driving shaft is rotated reversely. In addition, a controlling device for automatically controlling the transmission for the motor according to a load applied to the output side is also provided.
