The following detailed description of the accompanying drawings is only used to illustrate the preferred aspects of the present invention, and is not intended to represent the only form in which the invention can be made difficult. The following is a description of the functions and procedures that make up and operate the invention with respect to exemplary embodiments. It should be understood, however, that the same or equivalent functions and sequence of operations may be achieved by different specific embodiments that also fall within the spirit of the invention. In a specific embodiment (Figures 1 to 4), there are two sets of pulleys on two independent and parallel planes. The first group of pulleys A-E are the driven or input pulley groups, and the pulley A is the actual input pulley driven by the engine or the like. The second set of pulleys 1-6 is the output pulley set and is located on another plane. The driving pulley A moves the transmission belt F and the pulleys connected to the transmission belt F (that is, the pulleys B, C, and D in the lower gear in FIG. 1). The input and output groups of the pulleys are configured as part of a group of movable or rotatable gears in aligned pairs. In this embodiment, the output group 3-6 and the input group B ″ E are rotated together around the central axis 7 of the gear for moving the device. (For example, groups can be fixed to a single rotatable plate by bearings). In addition, the input group BE and output groups 3-6 of the pulley are each connected to the common shaft in pairs, so that the pulleys B and 3 rotate together, and the pulleys C and 4 rotate together, together with the pulley pairs D and 5 , E and 6 rotate together. From the diagram (picture 4), it can be seen that when the 5 is engaged (pictures 1-4), the pulley B turns the slowest (because the distance traversed by the transmission belt F is fixed), and the pulley E and therefore the pulley 6 will rotate. Fastest. The pulley 2 is an opened pulley.

I 548380 6214pif.doc / 006 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. The description of the invention (δ) can be the same size. Pulley B- is responsible for the circular movement ratio of pulleys A and 1. Alternatively, the ratio of the pulleys 3-6 can be determined by different radii. In the lower gear (Figure 1), pulley B engages the transmission belt F and becomes the slowest rotating pulley of the input gear group. Therefore, the handle wheel 3 in the output gear group which is engaged with the output pulley system transmission belt 8 makes the transmission belt rotate the slowest, and therefore makes the output pulley 1 rotate the slowest. In order to reach the second gear (2, Fig. 2), the pulley group is moved by rotating around the shaft (for example, by a step motor) (moving in a clockwise direction in the diagram). Fig. 2 shows the second gear, which changes the angular velocity along a common axis shared with the pulley 4 along the pulley edge moving at the penultimate slow speed of the input group. The pulley 4 is engaged with and drives the transmission belt 8. As can be seen from the diagram of the second gear (Fig. 2 ·), the pulley 3 can also be engaged with the transmission belt 8. However, because the pulley 3 moves more slowly than the pulley 4 (because the pulley B is slower than the pulley C), the transmission belt 8 crosses the pulley 3. The pulley 4 is most entangled and can be crossed by, for example, a clutch bearing. The pulley 3 can rotate together with the transmission belt, and if the pulley 3 is pressed counterclockwise. Because the pulley 3 only needs to be locked when it is pressed in the clockwise direction, the transmission of the transmission belt 8 in the second gear (Fig. 2) is added when the pulley 3 can rotate freely in the counterclockwise direction. _ In the third gear (picture 3), the pulleys 4 and 5 are engaged with the drive belt 8. However, the pulley 5 moves faster than the pulley 4, so the pulley 5 will be similar to the pulley 3 in the second gear due to the clutch bearing. (Figure 2) The way across. In the fourth gear (high gear), the pulley 6 moves more than the pulley 58 11 This paper size applies to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) ----------- install- -------- Order --------- (Please read the notes on the back before filling out this page) '548380 A7 B7 6214pif.doc / 006 V. Description of the invention (may) fast' Therefore It will freely rotate on its clutch bearing across the pulley 5 '. It is considered that the fourth gear pulley 6 does not necessarily require a clutch bearing, because the pulley set is never engaged with the output drive belt 8 at a more rounded ratio at the same time. Although this specific embodiment is described with the simple structure described above, the principle cannot be applied to a system that increases the speed by interchangeably playing the roles played by the output pulley / gear 1 and the input pulley / gear A. In the second specific embodiment (FIGS. 5-9), there are input groups ′ of gears G, Η, and I having a transmission belt J and output groups of gears 11 ′ 12 and 13 having a transmission belt 14. In this architecture, the movable gear groups are G, Η, and 11, 12 around the pivot axis. The gear group exists in the pulley pair G-11 and Η-12 in the second embodiment. The gear group is similar to the gear group in the first embodiment. In the high gear (second gear, FIG. 5), the gear 12 is not engaged with the transmission belt 14, but the gear is engaged with the transmission belt 14. Fig. 5 shows the high gear or the second gear in which the smaller / faster rotation of the input gear G and thus the slower rotation of the output gear 11 controls how the input drive belt 1 is loosened during transmission to the first or slow gear. In this specific embodiment, since the clutch belt automatically disengages during the movement of the gears between the gears, there is no need to cross the clutch bearing or the like. If a belt such as a compound V is used, the belt will slip off until re-engaged. Note that three engagement positions can also be created by adding the appropriate 的 th set of gears to the group. In the third specific embodiment (Figs. 10-13), the device is similar to the first specific embodiment, but is constructed using gears.

The input shaft 19 is along the input ring gear L and the input gear K- Rotate / move input gear group] Gear pair-connection at the center of VUP, and connection with output gear group 22-25. As can be seen from the first to fourth gears in the figure, the center 20 of the ring-shaped national gear L Will be converted to accept the gear pair radius that changes as the gear pair rotates and engages the output gear 2] ^ In the first gear (Figure 10), the wing or input shaft 19 drives the gear K, and sequentially drives the gear L, And therefore drive the gear M. The other gears also rotate without load. The gear 22 on the common shaft with the gear M drives the output gear 21. Because the gear μ has the largest number of teeth, the largest reduction is obtained. The gear group is around The shaft 19 rotates to provide the second to fourth gears as shown in Figs. 11-13. The output gear 21 meshes laterally (non-radially) with the gear train that it contacts and drives, so no stepping tooth Ira is required mechanism. The wheel seals also all rotate with the ring gear l *. Gears that share several gear teeth can change gears seamlessly. The invention is highly efficient because it eliminates the need for any clutch mechanism. Note that in this specific implementation In the example, the gears are configured as one of the other gears from the second ruler to the third gear due to the geometry of the gear group. A system for automatically changing gears is known in the art. These automatic systems can It is advantageously used in a specific embodiment of the present invention.
