This device includes a circuit board made of LSI, etc., a gear motor controlled by the circuit board, a detector for detecting the rotation speed of the wheels, and a battery that supplies power to these devices. Specifically, as shown in FIG. 15, the magnet 11 provided on the spokes 10 of the rear wheel of the bicycle is rotated by a rotation detector (magnetic detector) 12 fixed to a chain stay (cha in stay) or the like. Sensing is performed, and the remote speed § 5 tiger is analyzed by the circuit board 13 to obtain the vehicle speed. In addition, the circuit board 13 has previously stored a speed pattern of a transmission (not shown) (for example, corresponding to a shift position in a set speed range). When it is determined that a shift is necessary, the motor 1 4 Supply power. The wire 15 connected to the speed changer of the driving vehicle via the speed reducer 17 will be pushed and pulled in the direction of the arrow piece, and this will automatically switch the gear to the appropriate gear ratio. In addition to these devices, a battery 16 serving as a power source of each device is additionally provided. In this way, conventionally, at least the rotation detector 丨 2, the circuit board 丨 3, the steel wire 15 driven by the motor 14 and the battery are separately separated from each other on the bicycle frame. (Problems to be Solved by the Present Invention) However, since the conventional automatic shifting device for a bicycle described above is provided independently of each other, it is of course necessary to arrange the units.

Description of the invention (2), and the space for the original device to be installed on the bicycle is small (it is difficult to install the device within the range of rotation of the pedal), μ ㈣ " Ge Cong! : The frame of the automatic car will be full of installations, and there are problems in the design. In addition, since the transmission mechanism is driven by the wire rope, :: a substantial increase in ::, there is also a problem in the reliability of the point of readjustment, etc. as the wire rope is stretched and the like. However, as described above, the automatic transmission for bicycles,

(sensing) The speed and load of the yoke (Hunter yoke, J sound, halberd, stern plate load) can be automatically shifted regardless of the driver's car. At the same time, bicycle transmissions, whether they are built-in or not, are known to switch gears to change gears at first speed. Therefore, there is a property that the driving force is removed at the right r, that is, smooth shifting. The pedaling force of the Xiaoban cannot be performed. Therefore, the driver may change the speed while stepping on the concubine. And this not only prepares: if it is found that the accidental self-catch device or the motor for speed change is not smooth, it will also worry about the cause of the change. The present invention has been made in view of the above-mentioned matters, in addition to a compulsory burden. In addition to being able to be greatly reduced in size, the problem is to provide an automatic transmission for driving. The technical problem of reducing the number of parts is to provide an automatic transmission.

The wireless method 'manually shifts speed according to the driver's will. This 2' the above devices can be adjacent to the rotation detector 8 to be placed in the same place. Moreover, each device can be accommodated in the same way as the rotation detector 8 One housing 9. Therefore, 'only by mounting the housing 9 near the built-in transmission 2' is a fan-transmission device, and since wiring is not required, the reliability of the device can be greatly improved. In addition, 'because the control substrate 5 has a special resistance to impact or moisture,' if the wax is filled around the control substrate 5, the control substrate can be protected from vibrations generated when the vehicle is driven by two cars and two vehicles. The wax is a high-grade monovalent alcohol or a divalent alcohol that is insoluble in fatty acids and water-insoluble polymers. It is limited to those that will solidify at normal temperature. For example, such as carnauba wax and thread wax. Plant-based wax, or animal wax such as beeswax or wool wax. Page 8 88119123.ptd 531514 V. Description of the invention (5) After filling the wax, in addition to holding the parts by the wax itself, borrow The internal loss of the soil absorbs the vibration of the bicycle without causing metal fatigue at the welded part.

In other words, the driver shifts manually, and the driver operates a transmitter (controller) 3 provided on the handle 31, and the gear motor 4 is controlled by the receiver 5a in the housing 9 to receive the signal. ^ On the other hand, 'automatic shifting' detects the rotation speed of the rear wheel 7 based on the rotation detector 8 and controls the gear motor 4 in accordance with the shifting speed stored in the circuit board 6 in advance. For example, when the bicycle's speed is under 8km / h according to the turning speed signal of the wheel, the microcomputer (circuit board 3) selects a low speed gear (10w gear). When the bicycle is at a speed of 8km / h or more and 15km / h or less, the microcomputer selects the second gear. Similarly, when the bicycle is at a speed of more than bkm / h ', the microcomputer selects the third gear and automatically controls the built-in transmission 2 in this way. As described above, the position of the pins 3 in the frame 9 is extremely simple. There is no concern that the cable will stretch and cause the operating point to shift when the speed is changed via a wire as in the past. As a result, the device ’s trust1 will not only contain the device necessary for automatic transmission, but also The actuator is built into the lever that can directly push the gearbox, so the installation of the automatic gearbox on the bicycle can be changed.
