The internal transmission is usually based on the planetary gear train as the main transmission mechanism-and the transmission mechanism is placed in the rear wheel hub, so it is called the internal transmission, and it is called the multi-speed hub in China. The gear ratio of the planetary gear train is changed by switching different input parts, output parts and fixed parts to achieve different speed ratios. [Previous technology]. The internal transmission with the planetary gear train as the main body of the transmission mechanism has the following advantages: 1. Small size; 2. Stable shifting operation; 3. Protective life of the wheel hub; 4. Low noise, these advantages are just fine It is suitable for bicycles used in recreational sports. In recent years, for very hot electric scooters and electric bicycles, the [internal transmission has become its standard equipment, so the demand for internal transmissions has tended to increase. The major bicycle factories in the project have also begun to attach importance to the research and development and design of internal transmissions. The innovative design theory and methods of transmissions have gradually become the key work for domestic major bicycles. Looking at the patents of the bicycle's internal transmission mechanism, we know that the five-speed internal transmission is as known: China Patent Publication Nos. 330544, 342795, 399534, and so on. U.S. Patent No. 388681 1, No. Μ "M, No. ⑺u, No. 5078664, No. 58555330, No. 6039671, etc. At present, there are still uneven distribution of gears in multi-speed internal transmission products. Component M282914 has too many numbers, large volume, and heavy weight. Therefore, how to design a bicycle that is early, heavy, light, and multi-speed is an important research topic. "It becomes an extremely [new content] book The purpose of the creation is to provide a new structure whose distribution of gears is evenly distributed and symmetrical. The structure: the five-speed Ai speed machine ... the number of components can be less than 30,

Secondly, the “protruding teeth & bolts” on the speed control lever are used effectively to switch and drive different input parts, output parts and fixing parts, so that the total length of the internal transmission can be minimized and tightly used. In addition, the purpose of this creation is also to provide a kind of transmission whose component design is simple, and it is easy to make guards, which can save extra time and reduce man-hours. 1 [Embodiment] Please refer to the figure-it is a combined view of the embodiment of the present invention. The five-speed internal transmission of the bicycle in this creation mainly includes two parts of the speed regulation system of the speed change mechanism. The main body of the transmission mechanism includes two sun gears (451, 452), two sets of planetary gears (421, 422), a planetary arm (^), and a ring-shaped wheel (41), which is responsible for inputting the rider's footsteps. The speed of the engine is output to the rear wheel hub (51) after being converted between the planetary gear trains, so as to achieve the purpose of driving the self-driving car. When the rider's foot passes through the chain to the input sprocket (52), the input sprocket (52) is fixed to the outer ring of a flywheel seat (53), and a ball bearing is fitted on the inner end of the flywheel seat (53) with a ring. (561) Connect the side cover (551) to pivotally input the flywheel seat (53). The input end is provided with a speed regulating ring (32), and a toothed bolt (321) is grown on the flywheel seat (53), and then the ring gear (322) of the speed regulating ring of the input terminal is used to drive the ring gear ( 41) or planetary arm (43) for transmission. When power is output, the speed control ring (33) is driven by the ring gear (332) of the output speed control ring through the ring gear (41) or the planetary arm (43). The output flywheel seat (54) is closed, and the power is transmitted to the output flywheel seat (54). Finally, the flywheel seat (54) is used to drive the wheel hub (51) to transmit the power to the rear wheel to output power. A wheel hub (51) 'is also provided with a ball connection side cover at one end of the inner side of the wheel hub (51)', which is used for relative movement between the wheel hub (51) and the fixed main shaft (11). In the gear mechanism of the transmission mechanism, it is sleeved on the outer side of the fixed main shaft (11) and mounted on the inside of the wheel hub (5 丄), and sequentially sets a sun gear (451) with 60 teeth and a sun with 36 teeth. Gear (452), and two planetary gears (421, 422) with 30 and 54 teeth, which are coupled to different sun gears (451, 452). The planetary gear train consists of a planetary arm (43) and a planetary gear core. The shaft (44) penetrates and fixes the planetary gears (421, 422), and simultaneously engages a ring gear (41) on the outside of the two sets of planetary gears (421, 422). In this way, the transmission mechanism of the present invention is composed. Please refer to the first picture, the speed control system of the second part of this creation. The speed control system includes a speed control sleeve (31), a speed control slider (34), a return spring (35) and two speed control systems. Speed ring (32, 33), the speed is controlled by the speed control cable (211) via the chain (212) to pull the speed control lever (213) to move left and right, the translation control lever (213) pushes the slider (34) to move The speed control sleeve (31) is placed on the π block (34) and is pulled from left to right. When returning, the speed control sleeve (31) can be pushed back in the opposite direction by the force of the recovery bomb κ (35). . Put a speed governing ring (32, 33) on the outer side of the front and rear ends of the speed governing sleeve (31). It is used to cut M282914 to change the input and output rods. Because of the purpose of the speed governing ring (32, 33) Because the driving rod is used for transmission, the speed control ring (32, 33) is not completely locked on the speed control sleeve (), and the ° peripheral speed sleeve (31) except for the speed control ring (32, 33), Mainly: The knife changes the solid sun gear (451, 452), so it won't rotate proudly.
