Jiu 6 1285613 The main body of the underspeed mechanism consists of seven components consisting of four sun gears, a set of fourth-order planetary gears, a planetary arm and a ring gear. Nine different speed ratios can be achieved with fewer components. Requirements. Secondly, the protruding teeth and the bolts on the speed control unit can be effectively utilized to switch between different input parts, output parts and fixing parts, so that the total length of the internal transmission can be minimized and closely used. In addition, the purpose of the present invention is to provide a multi-speed transmission design, which has a simple design method, easy processing, and can save processing costs and reduce man-hours. [Embodiment] Please refer to the first figure, which is a combined sectional view of the creation embodiment. The bicycle nine-speed internal transmission mainly includes two parts of a shifting mechanism and a speed adjusting system. The main body of the shifting mechanism includes four sun gears (441, 442, 443, 444), a set of fourth-order planetary gears (43), a planetary arm (42) and a ring gear (41), which are responsible for borrowing the rider. The speed input by the pedal is converted to the rear wheel after being converted between the planetary gear trains, thereby achieving the purpose of driving the bicycle forward. 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 the two ends of the flywheel seat (53) are respectively matched with the ring ball. Bearings (541, 542) connect the side cover (5 51) to the wheel hub (51) to pivot the flywheel seat (53). The input end is provided with a speed regulating ring (34) 'the upper tooth bolt (341) is meshed with the flywheel seat (53), and the ring gear (41) is driven by the tooth bolt (342) of the input end regulating ring or The planet arm (42) is driven. There are two methods for power output, one of which is to drive the wheel hub (51) via the output armature (422) via the planetary arm (42); the second is to use the ring gear (41) to translate the power by the ring gear ( 41) Actuate the wheel hub (51) through the 7 1285613 one-way pawl (411). Finally, the power is transmitted to the wheel hub (5 1 ) for outputting power on the rear wheel, and at the inner end thereof, a ball (543) is also connected to the side cover (552) for the wheel hub (51) and the fixed spindle. (11) Do relative movement. In the gear mechanism gear set, it is sleeved on the outer side of the fixed main shaft and mounted on the inner side of the wheel hub (51), and the sun gears (441, 442, 443, respectively, having teeth 66, 63, 57, 44, respectively, are sequentially arranged. 444), and a set of fourth-order planetary gears (43) that engage four sun gears (441, 442, 443, 444) having teeth of 13, 16, 22, 35 teeth from right to left, respectively (431, 431, 432, 433, 434), the planetary gear (43) is penetrated by the planetary arm (42) through the planetary gear spindle (421) and fixed to the planetary gear (43), and has a number of teeth on the outer side of the planetary gear (43) The ring gear (41) of 45 meshes, thus forming the shifting mechanism of the present invention. Referring to the first figure, the second part of the speed control system of this creation includes a speed control sleeve (31), a speed control slider (32), a speed control ring (34) and two return springs ( 351, 352). The speed adjustment is performed by the speed control cable (2 11) pulling the speed control rod member (213) through the chain (212) to move horizontally, and the translation control rod (213) pushing the slider (32) to the groove of the fixed main shaft (12) In the middle translation movement, the speed control sleeve (31) is sleeved on the slider (32) and is pulled from left to right. When returning, the speed adjustment sleeve (31) can be pushed back by the force of the return spring (351). return. A speed regulating ring (34) is arranged on the outer side of one end of the speed regulating sleeve (3 1) on the slider (32) and the fixing ring (33), because the purpose of the speed regulating ring (34) is to drive the rod to drive, Therefore, the speed control ring (34) can rotate relative to the speed control sleeve (31). When the speed control sleeve (31) drives the speed control ring (34) to be pulled from left to right, the ring gear 8 1285613 = (41) follows from right to left, and conversely, by the force of the return spring (352) Pushing the ring window wheel (41) back in the reverse direction, so as to achieve the lever transformation control of the output end by the splint (4(1) and the wheel hub (9) on the ring gear (31). In addition to driving the idle speed ring (4), the main purpose of the speed sleeve (31) is to cut and fix different sun gears (441, 442, 443, 444), so the speed control sleeve (31) does not rotate. The operation of the nine gear positions is illustrated in part (a) of the second to tenth drawings, and the part (b) of the drawing corresponds to the road map for drawing the energy transmission, wherein the black line and the arrow indicate the power The path of transmission, the hollow square shape represents the joint function without meshing, and the solid square represents the meshing connection. In this regard, firstly, the operation of switching to the first groove is illustrated by the second figure. The user drives the chain to drive the sprocket (52) in a pedal manner, and then the sprocket (52) drives the fly. When the seat (53) rotates, the flywheel seat (53) drives the speed control ring (34), and then the gear pin of the speed regulating ring (34) drives the ring gear (41) to rotate, and the gear bolt on the speed control sleeve (312). ) is engaged with the sun gear (441), while the planet arm (42) drives the output ratchet (422) placed thereon, and finally transmits power to the rear wheel via the wheel hub (51). The torque from the input is increased. It is 1.855 times, so it can be used as a starting gear for riding bicycles. Please refer to the third figure, which is a combination sectional view and energy transmission route diagram of the switching to the second gear position of the present embodiment, when the gear position is When Yiyi switches to the second gear, the speed control system moves from right to left, and the ring gear (41) is also translated from right to left by the force of the return spring (351). This = speed control ring (34) ) still meshes with the ring gear (41), and the output end is still driven by the output ratchet (422) to drive the wheel hub (51), so the energy transmission path is the same as the first building phase 9 1285613, but the speed regulating sleeve (31) is left When moving, the gear bolt (3i2) of the speed control sleeve leaves the sun gear (441), and the other tooth bolt (313) and the sun gear (442) The phase matching 'make the purpose of changing the different fixed rods. The torque is changed from the input output to 1.663 times. Please refer to the fourth figure, which is the combined sectional view of the creation of the third embodiment. And its energy transfer road map, when the gear position is changed from the second gear to the second floor, the speed governing system continues to translate from right to left, and the ring gear (41) is also controlled by the force of the return spring (352). Shift to the left, at this time the speed control ring (34) also meshes with the ring gear (41), and the output end also drives the wheel hub (5 1} by the output ratchet (422), so the energy transmission path is the same as the first gear position. However, the gear pin (314) of the speed control sleeve is meshed with another sun gear (443) to make the sun gear (443) fixed. Its torque is changed to 1.436 times from the input output. Please refer to the fifth figure, which is a combined sectional view of the fourth embodiment of the present embodiment and an energy transmission route diagram thereof. When the gear position is changed from the third gear to the fourth gear, the speed governing system continues to be The right-to-left translation is performed, and the ring gear (41) is also translated from right to left by the force of the return spring (352). At this time, the input end-loss ring (34) is also meshed with the ring gear (41), and the output end The wheel hub (51) is also driven by the output ratchet (442), so the energy transfer path is the same as the first gear position, but the gear pin (315) of the governor sleeve is transformed to engage the other sun tooth wheel (444) to make the sun The gear (444) is fixed. Its torque is changed to 1.212 times from the input output. Referring to the sixth figure, it is a combined sectional view of the fifth gear and the energy transmission route diagram thereof. When the gear position is changed from the fourth gear = 1285613 to the fifth floor, the speed is adjusted. The system continues to translate from right to left, and the ring gear (9) is also translated from right to left by the force of the return spring (352), while the pawl (411) provided outside the ring gear pops up with the wheel wheel (51) To sum up, the 'ring gear (4)) and the output ratchet (422) on the planet arm (42) simultaneously drive the wheel hub (8), but due to the overspeed action, the ring wheel (4) rotates at a faster rate than the star arm (42). ) fast, the input ratchet (422) and the wheel hub (1) cannot generate the spray β. At this time, the power is directly outputted via the ring gear (41), and the gear bolt (315) of the speed control sleeve continues. Fixed the sun gear (4) sentence, so the torque of this gear remains unchanged, also known as direct drive gear. See the seventh figure $No for °°, which is the combined sectional view of the sixth gear and the energy transmission route diagram of the embodiment. When the sand level is changed from the fifth slot to the sixth gear, the tone is adjusted. The speed system continues to translate from right to left, the input speed adjustment % (34) is switched to connect with the planet arm (42), at this time the ring gear (4)) ^ does not move, 'by the one-way pawl (411) The wheel wheel (5 ι) is used as the output sun gear sleeve (31 5) to fix the same sun gear (444), and the torque from input to output becomes 〇825 times. "Monthly refer to the figure of the person's figure is not a combination of the embodiment of the switch to the seventh position of the sectional view and its energy transfer road map, when the gear position is changed from the sixth gear to the seventh gear, the speed control system Continuously shift from right to left. At this time, the input end is connected by the shoulder speed soil (34) to drive the planetary arm (42), and the output end is driven by the outer gear one-way pawl (411) (four) wheel hub (9). The tooth bolt (314) on the speed control sleeve is switched to the other sun gear (443), and the torque from the input to the output becomes 0.696 times. Please refer to the ninth, which is a combination sectional view of the eighth gear 11 1285613 & and the energy transmission route diagram is replaced by the eighth broadcast, and the speed control system continues to be translated from right to left. The speed control ring (10) is connected with the planetary arm (6), and the output end drives the wheel hub (5ι) as a tooth pin (312) on the left side of the ring by the one-way pawl (411) of the ring ^ (4) Wheel (10)), the torque of 卞8 into the output becomes 0.601 times. The bit fL is shown in the tenth figure, which is switched to the ninth gear for the first embodiment and the second: the figure: and the energy transfer route diagram 'when the slot is changed from the eighth broadcast to the ninth The speed control system continues to translate from right to left, ^ is connected to the planet arm (42) by the speed control ring (10), and the wheel hub (51) is driven by the ring gear (called the outer one-way pawl (411)). At the material output end, the tooth bolt (312) on the speed control sleeve is changed to the mouth and the torque from the input to the output is 0.539 times. () Please refer to the tenth-figure, which is the creative embodiment. The broadcast position is actuated two::: The above-mentioned nine-position niches are respectively divided into the talents, output rods and fixed rods that are switched by each broadcast, and are listed as a nine-speed caster, which is already in the table. When the number is switched to the slot, the rod has meshing and meshing. Among them, the speed ratio of the nine-speed gear is W55, i 663, ^36, including four low-speed buildings and four ancient apricots. Four speed-shifting gears and one direct drive gear, the gear ratio is 3443⁄4. According to the above description, this creation is characterized by its first proposal. When the nine-speed internal transmission design is changed, the special design of the shifting system makes the design of the speed-regulating rods more compact, reaching a smaller space of 12 1285613.
