Description

[Detailed description of the invention] No changes to engraving contents Background of the invention The present invention relates to bicycle transmissions, particularly those that respond to applied power. It relates to automatic transmissions for bicycles that rotate and change gear ratios as the vehicle rotates.

Transmissions for rotating cars use telescoping goggles depending on the gear ratio or the force applied to the pedals. For example, between the sprocket gears shown in U, S special edition N○3.99F・, 508. It is something that changes automatically.

In this patent, the effective diameter of the sprocket ring is defined by the number of interacting sprockets [ - changed by changing the radial position of the gear. Sprocket gear diameter Directional positioning is a function of human torque, so increasing the torque will increase the The effective diameter of the proket wheel is reduced. Conversely, if you reduce the pedal input torque, the spring The radial radius of the sprocket gear increases due to the action of the sprocket gear.

In the structure of the patent No. 3,995,508 mentioned above, the distance between the sprocket gears is Due to the situation where it is necessary to directly change the effective width diameter, it is difficult to engage the chain. Between the sprocket gears in the position? The unidirectional hook can be adjusted so that the h distance can be changed. I had no choice but to install a latch.

In conventional bicycle automatic transmissions, the effective diameter of the sprocket wheel The increase and decrease of the torque is not smooth, and when the drive sprocket and drive chain are engaged and disengaged, it is always unnecessary. Unpleasant noises and shocks are generated when operating the lance transmission. 1. There was a problem that became worse during races.Furthermore, the conventional technology In this case, the ring should not be engaged or locked with the subrocket 1, especially from the radial direction. There were some drawbacks. Therefore, the predetermined torque is, for example, inertial operation or ←1! Time (J solution When the sprocket is released, the sprocket is immediately moved to a position where it can advance radially. There is a risk that it will be energized. Furthermore, the conventional automatic transmission has a W4 structure. Extreme - C tends to be complicated and troublesome, which increases manufacturing costs, bulk, and maintenance costs. Moreover, it also increases the weight and number of parts, and tends to cause fatigue and fatigue. there were.

Meeting summary The present invention relates to automatic transmissions for bicycles, and in particular Automatic chain engagement can be performed without any trouble, and automatic locking can be performed within a predetermined gear ratio. This invention relates to an improved expandable sprocket mechanism.

The present invention features a pedal that is attached to the pedal shaft and rotates with the rotation of the pedal arm. The reference shaft has a predetermined diameter and is rotatably provided on the shaft. The basic i-wheel is a pedal arm. a first pair of radially oriented slots aligned generally axially with the pedal arm; a second pair of radially oriented slots extending substantially perpendicular thereto; . The small diameter link ring is coaxially connected to rotate relative to the base transport, and the required torque is It is designed to automatically rotate according to the Multiple conflicting links are small diameter links The outer peripheral edge of the ring and the reference shaft are internally connected at a position to the thrower 1. Semi-circular, arc-shaped The pair of drive sprockets that have been set are in a state where the pedal arms of the reference axis are aligned in a straight line. The chain slides are mounted facing each other in the slots of the The two are placed facing each other in slots that differ by 90 degrees in the circumferential direction of the shaft. This constitutes a drive wheel that can advance and retract. compression spring pedal MΩ(-1) is attached to the arm, and the movable horn link is attached to the drive sprocket and chain slip. Multiple links are always biased in order to pull the id toward the external large diameter position. The small diameter is biased to rotate.

If the cyclist applies a lot of force when climbing a slope or hill, multiple drives The sprocket and chain slide automatically retract and the sprocket (= 1 force) to overcome the transformed into something. The drive sprocket is therefore forced into the pedal position by the cyclist. When pulled radially inward by a torque applied to the is applied via the transmission, and the rotation speed of the pedal arm relative to the rear wheel is increase. Cyclists stand on the pedals as more power is required. This causes the drive sprocket to build up by unconsciously using more energy, such as by raising the The drive wheels automatically retract to overcome the spring pressure. The driving force that shrinks The chain slides or If in right angle direction, automatic locking of drive sprocket 1~ at 1-lux adjustment radial position is performed and the torque to the pedal arm is released, the effective diameter of the drive wheel is Reduction is closed until it is desired for the equalist to advance. Place where you want to expand the compression spring forces the drive sprocket and chain slide into the extended position Rotate the pedal in the biased distraction direction.

In this way, expansion or contraction of the effective drive diameter of the drive sprocket or drive wheel is Complete control by adjusting the circumferential angle of the dull arm! I'll be ignored U (Konaru)

Preferred embodiments of the invention Certain terminology is used in the following explanations for clarity; This is only to refer to the specific structure of the invention adopted for the purpose of It is not limited or regulated.

Referring to the drawings, FIGS. 1 and 2 show a bicycle automatic transmission designated 1o. A pedal crank 14 is illustrated for chain drive purposes. It consists of a drive pedal arm 12 mounted so that it can rotate as shown in FIG. central hub 1 5 is fixed to the crank 14 by, for example, a bolt 23 and a nut 25, and the crank rotates. It is rotated at the same time as it is rotated. The link wheel 18 is connected to the central hub 1 by a bearing 20. 5 and a force directed radially inward and radially outward, as described below. is applied to the sprocket 78.80, and the chain 84.86 is now able to slide. ing. The reference axis of the sprocket adjustment wheel is 22 degrees, and the center hub 15 is set to the sat 16. This allows the base ring 122 to be attached to the central hub 1b or the pedal arm. As it is rotated by the arm 12, it is rotated. This basic transportation 22 is in the radial direction a pair of first slots 24, 26 which are oriented toward the pedal and match the pedal in a vertical relationship; A second pair of shafts are positioned at 90 degrees to the axis of the dull arm 12 and are oriented in the radial direction. Consisting of lots 28 and 30. The plurality of openings 32 are sprocket-like for weight reduction. It is provided on the wheel adjustment 22. A plurality of pivot links or arms 36 as shown. ．． 38, 40.42 automatically connects the link wheel 18 to the sprocket adjustment wheel 22 as described later. They are connected for the purpose of adjusting the gear ratio. Each link 36°38.40.42 is Its inner end is pivoted *44. / +6.48°50 to link ring 18 pivotally This allows the link and link wheel 18 to rotate. link or art Each of the arms 36° 38, 40, 42 has its outer end or other end connected to a pivot pin 52, 54. , 56, 58 to be pivotally connected to the sprocket transport 22. Pivot bottle 52, 54, 56, and 58 are each attached to one of the four slide blocks 60. , this block 60 preferably has a rectangular shape, and has vertically arranged throwers [~24, 26 or one of the vertically aligned slots 28, 30. engage by sliding in the direction. Therefore, the sprocket-like V-wheel 22 is the link wheel 18. The hub 15 rotates with the rotation of the hub 15 by the pedal arm 12. 3. This reverse movement is caused by multiple slots oriented in the radial direction. A similar radial movement of the slide block 60 within the slots 24,2 6,28.30 will be compensated. In Figures 1 and 2, the l\tal arm 12+ is coil spring 62 (preferably this coil spring 62). It surrounds the arm 12 and biases the adjustment collar 64 and the operating protrusion 66. child The collar 64 is screwed into an external threaded portion 68 at the proximal end of the arm 12, and is screwed forward and backward. tone Node openings are provided at the periphery of the collar 64, and if it is desired to adjust the spring tension, The rotation of the collar 64 on the threaded portion 68 is shown in FIG. The spring 62 maintains the protrusion 66 The protrusion is attached to the pedal arm 12 and the crank 14 is attached to the outside. They tend to be far apart from each other. The protrusion 66 is located at one end of the moving horn compensation link 72. They are pivotally connected by a pivot pin 97. The flat insert 99 is attached to the pedal arm 1 2 to prevent the protrusion 66 from rotating relative to the pedal arm 12. do. The other end of the power compensation link 72 is pivotally connected to the link wheel 18 by a pivot pin 76. is internally connected to. As clearly seen in FIG. 1, the pivot pin 76 is connected to the pivot pin 9. 7, they are aligned in the radial direction by about 5 degrees to 10 degrees, but are shifted in the circumferential direction. child As a result, the spring 62 acts via the protrusion 66, and the link ring 18 is continuously clicked. It is biased to rotate clockwise around the rank 14. The bearing 20 is replaced as described later. Rotate the crank wheel 18 around the pedal crank 14 and around the sprocket adjustment wheel 22. encourage people to move. As shown in Figure 3-7, a pair of radially opposed arcuate The pieces 78 and 8 of the forming block 1 are diametrically opposed and aligned vertically on the arm 12. It operates in the radial direction along each slide block 6o.

Sprocket] - A pair of diametrically opposed pieces 78 and 80 are adjustable in the radial direction. 84 and 86 are located there.

This chain slice l'g84.86 is attached to the slide block 60. This block 60 reciprocates in the child\h direction within the vertically aligned slots 28°30. . Therefore, the sprocket pieces 78.80 and the chain slide pieces 84.86 are automatically in conjunction with the torque applied to the pedals 88 in the slots 1 to 88 facing the opposite direction. The movable radial slot has a first large diameter, low casing 98 (FIG. 3, 4 and 7) and the reduced diameter, high-strength circle 100. (No. (See Figures 5 and 6). Figure 3-7 shows the operation of the automatic transmission device 10 and the automatic locking mechanism. Characteristics can be seen. In the rotational position shown in Figure 3, the sprocket pieces 78, 80 and the chain 84.86 is shown in the enlarged circle or lower casing circle 98. , this lower casing 98 is a sprocket engaged with a link of the drive chain 82. Oriented in the direction of the leading tooth 102 of the piece 78. On the other hand, the diametrically opposing sprocket The leading edge teeth 112 of the top piece 80 also engage the links of the chain 82. The teeth of the sprocket pieces 78,80 engage the opposing links of the drive chain 82. This locks the device against coarse radial expansion and contraction.

Note that the sprockets 78 and 80 are shown oriented in the low casing direction. However, a similar locking condition between the sprocket [-piece 78 and 80 and the chain 82 is The position of the rocket can be adjusted radially across all gear ratios. Immediately From the fully expanded position in Figure 3 to the fully contracted high position 10 in Figure 5. Niwa lji.

When the pedal arms 12 and 96 are in the rotatable position as shown in FIG. 82 ten end chain (when two horizontal forces are applied, the block 60 and the long slot 26, and this reaction acts only on the outside in the radial direction as shown by arrow 106. do. Therefore, in this position no forces directed radially inwardly are generated within the slot 26; Therefore, there is no tendency for the sprocket pieces 78, 80 to shrink.

Subrokets 1-piece 78.80 and chain slide 1-82.84 are pre-low bulk. coil spring 98 (if it has contracted until it is located in the radial direction) The slide block 60 is not biased radially outwardly as shown by arrow 106.

This is because the links between the front teeth 102 and 112 of the sprocket pieces and the drive chain 82 This is because there is a Lock King 1 effect with (see Figure 6). Pedal arm 12 When the sprocket piece 78 is rotated by 45 degrees at the (87 position; A number of sprocket teeth engage the upper end side chain that is continuous with the partner of the chain 82. similar During this rotational cycle stage, a plurality of diametrically opposed sprocket pieces 80 The teeth also engage successive links in the upper side chain of chain 82. Therefore spacing When engaged with the sprocket 78, 80 or the spacing link of the chain 82, the device is locked against further expansion and contraction in the radial direction. this position Now, the reaction to any horizontal force applied to chain 82 is the force arrow Directed backwards as shown in the direction 104, and in the direction of the force arrow 106 (two continuous forces) 110 acting in the direction of arrow 110 of [j], which is sufficient to overcome the biasing force of the spring. There is no power to become. For this reason, sprocket piece 78.80 and chain slide 82.84 means that when the pedal is in the position shown in Figure 4, it will neither expand nor contract. ．． ;i5 It should be noted that it is 90 degrees from the position of arm 12 in Figure 4 to the position in Figure 5. Then, the sprocket pieces 78 engage the links of the chain 82 and are diametrically opposed to each other. The tooth 80 of the covering subblock 1 rotates and comes off the chain 82, so that the tooth 80 in FIG. At the position , the engagement for ROTS〈7 is not delayed. In this position, there is no force applied to the pedal. , the reaction in the direction shown by the force arrow 110 (see Figure 4) is in the direction of the horn arrow 106. If the culm is strong enough to overcome the biasing force of the spring 62, the sprocket piece 78.80 and chain slat 82. ε) 4 are those links or arms 36.38, 40.42, the link ring contracts in the radial direction, thereby making the link ring flexible. move. This time, the power compensating link 2 moves the operating protrusion 66 by the rotation of the link wheel 18. The coil spring 62 is biased to be pulled inward in the radial direction and compressed by H. pedal Arms 12.96 are positioned to accommodate chain reaction and are longitudinally aligned with each other. Acting radially inward along the rows of slots 24,26, the pedals 88+2 If the resulting force exceeds the (=1 force) of the spring 88, multiple subblocks [-The shrinkage of the piece and the chain slide piece occurs, which causes the diameter large and low casing 98 From then on, I moved to Kokodaka Circle 100. When each member is oriented in this way, Chain 82 upper rut side button (when horizontal force is applied, a reaction occurs and the long length% g force direction slot 2 (j) (See figure) 1 no [1 obtained l: 1 ~ If it is larger than the biasing force of the spring 62, the arrow E!

Apply force to reduce the size (see Figure 5).

Added torque or coil spring 6? If the biasing force is smaller than the arrow 106 direction [Spring force acting in this direction and directed outward in the radial direction (J sprocket piece 78, ’80 and chain slide 82°84 or low force sword - 98 direction (this expansion lever I will encourage you to do so. As mentioned above, Subroket I ~ piece 78.80 or Figure 3, Figure 4, As shown in FIGS. 6 and 7, as long as the chain 820 is engaged, The device is locked against radial outward expansion and radial inward contraction. be. The sprocket pieces 78 and 80 and the chain slide pieces 82j and 84 are reduced. The pedal arm 12 is moved from the position shown in Figure 4 to the position shown in Figure 6. When VJ twists, it overcomes the force directed inward in the radial direction or the biasing force of the spring 62. Only if it is added to a moderately large amount. Sprocket piece 78.80 and chain The slide pieces 82 and 84 return in the radial direction between the expansion position 98 and the contraction position 1'00. When moving, the length of the chain 82 is adjusted as necessary, as is well known. It is automatically adjusted by a derailing vane (not shown) energized by a fling. Figure 8 and with reference to FIG. 9, automatic engagement of chain 82 to sprocket piece 78. Operation is shown.

As can be seen, adjacent rollers 1. The distance 1 between the solid axes of 'i8.118' is The distance between the adjacent tooth pieces 120 and 122 measured after adjusting to approximately the pitch circle of the sprocket piece 78 2. Accurately aligns with the chain roller and connects it to the chain roller. trying to engage. Therefore, the adjacent chain [l-ra 118.118' Between the shafts rc 1ifi i, i outside [Thi 28te total 111ri 1lJt le &120. 12217) is smaller than the arcuate distance between centers. Circle the chain engagement Since it is very important to smooth the sprocket, make sure to use the chain 82. and directly engages each roller 118, 118' of the chain. And then The diameter measured by the pitch circle of the sprocket piece and the outer surface of the sprocket 1 to I'l The difference between the diameter measured by 128 and the diameter of the chain adjacent to 120, 1.22 It automatically and smoothly falls into the 124 formed between Practical use of engagement that does not require engagement. Figure 9 shows the sprocket tooth 102 at the tip and the chain row This figure shows one part of the ridge where the engagement with the la 118 or 118' begins. , the engagement is such that the central part of the chain rollers 118, 118' is on the outside of the teeth 122. Indicates that it is initiated by hitting a surface. Because adjacent chi x-:z D-7118, 118' (D center distance) ib l! llc, inside the outer surface 128 It is smaller than the distance between the adjacent teeth 120 and 122 measured by g1, and the following The chain roller 118' is slightly smaller than the rear adjacent subblocks 1 to 102'. This is because it is located in front of the crab. Similarly, the subsequent chain 82 is The roller 118'' further engages a rearwardly adjacent tooth 102'' that partially contacts the front surface 130. Zuru. As a result, the rollers 118, 118', 118'' automatically and smoothly pulled downward to point inward.

In addition, it is formed as a part of the circle 270971~piece 78.804i, and the subblock The difference in diameter between the pitch circle of i~, the sprocket, and the in-plane diameter by 7 people (well, in - -2118,11ε3′,ko] 8 pa or yen smooth Functions to automatically enter subblock l-iL 126 for chain engagement.

According to the structure shown in FIG. 8, the tip of the sprocket tooth 102 and the chain roller]]8 Initiation of engagement with the tooth 102 occurs at the leading edge or front surface of the face of the tooth 102.

Therefore, the trailing roller 118' is placed in front of the rearwardly adjacent sprocket tooth "1122'." Engage and cover the surface (depending on the distance between adjacent sliding rollers 118, 118' or in-plane 128) as long as it is smaller than the distance between adjacent teeth 102, 122' when measured ).

In the same way, the roller 118'', which is further spaced further rearward, touches the adjacent tooth further rearward. The M end of the groove 124 engages more closely at the front. This allows the roller 118, 118', 118'' all automatically and optionally cover adjacent sprockets The tooth grooves 124 enter respectively. Teeth 102°120 of sprocket piece 78 as shown ', 122 are circular to the adjacent helical rollers 118, 118', 118' of the chain 82. With smooth and automatic engagement, the roller automatically enters the sprocket 124. Moreover, , at this time, in which direction the engagement between the roller and the front edge of the sprocket 71 to the piece 102 starts. Even when I wake up, there is no chattering or sound.

Although the present invention has been explained within a predetermined range, this water valve is merely an example, and the structure The details can be modified in various ways, and the arrangement and combination of parts may go beyond the gist of the invention. It can be modified in various ways without my understanding.
