Description of the Invention: TECHNICAL FIELD The present invention relates to a bicycle, and more particularly to an internal transmission of a bicycle. [Prior Art] Bicycle transmissions can be generally divided into two categories: external transmission and internal transmission. Usually, the external transmission adopts an open chain mechanism as the transmission system. Although it has the advantages of simple structure and easy processing, it has unstable shifting action Φ. The exposed life of the components is short, and noise and other shortcomings are generated. The internal transmission is a closed planetary gear train as the main body of the transmission. In addition to the small size and space, it can be installed in the rear wheel hub. It can improve the many shortcomings of the above-mentioned external transmission and provide better transmission performance of the bicycle. Therefore, the bicycle industry has recently focused on the improved design of the internal transmission. In terms of specifications, the internal transmission has been gradually developed and improved by the initial two-speed. It has evolved into a variety of internal transmissions such as three-speed, four-speed, five-speed, seven-speed, nine-speed, and twelve-speed, such as the announcement number. No. 392, 661, "The shifting body of the self-propelled internal transmission" is a three-speed internal transmission, as described in U.S. Patent No. 3,880,811, U.S. Patent No. 4,651,853, U.S. Patent No. 4,721,013, U.S. Patent No. 5,078,664, U.S. Patent No. 5,855,530, and No. These are all five-speed internal transmissions, while U.S. Patent No. 5,273,500, U.S. Patent No. 5,399,128, and U.S. Patent No. 5,562,563 are among the seven-speed internal transmissions. In the above-mentioned multi-speed internal transmission, such as a five-speed or seven-speed internal transmission, the number and types of components are relatively complicated, and it is necessary to open a large number of molds, and the system 1 5277561 has a high cost and a large overall volume. The present invention, however, provides a six-speed internal transmission that can improve the above-described deficiencies and is innovative in construction. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an internal transmission of a bicycle that is simple in construction, innovative, and capable of functioning only. Therefore, the internal transmission of the bicycle of the present invention comprises a fixing member, an input member, an output member, a first shifting unit, a transmission unit, a second shifting unit, a first clutch, a second wheel, and a clutch. Second = clutch 'and a brake control unit. The input member is rotatably held on the member for inputting power. The wheel is wound around the fixing member and the second member is used for power output. The first shifting order μ is disposed between the fixture plate output members and includes - is driven by the wheeled member 曰 >: the sun gear, the second sun gear, and the more: the boom is balanced and sprayed at The first planetary gears around the first and second sun gears. The transmission unit is driven by the first shifting unit. Two ^ two are set between the fixed parts and the output parts, and include _ second two: catch (four) sun gear, and most of the two with the second planetary arm: 仃, a third male gear, with the honour *, τ and The second planetary gear unit connected to the third toroidal shifting gear is driven by the first planetary gear to drive in one direction, and the first to the clutch is interlocked with the transmission unit and can be driven by one direction. The second output clutch can be driven by the second planetary arm to unidirectionally drive the wheel output member. The third wheel output unit is mounted to the fixed member and the first and second variable members. The brake control control makes the first...the three sun gears::, can be used for selecting the fittings, or the three are not joints: or two of them 6 1277561 The foregoing and other technical features, features, and advantages of the present invention will be apparent from the description of the appended claims.
