However, even more in (a) and (b) of FIG. 38, the radius (r ₁₎ of the pitch circle of the second planetary gear 104. In other locations, the ring gear 106 in (a) of FIG. 38 in Since the radius r ₂ of the pitch circle of the ring gear 106 becomes large in 38 (b), the number of ring gear teeth in FIG. 38 (b) is larger than the number of teeth of the ring gear in FIG. 38 (a). do.

38A and 38B, when the ring gear 106 is fixed and power is input to the sun gear 101, and power is output to the carrier 102, FIG. Comparing the rotation ratio in (b), the rotation ratio in FIG. 38 (a) is different from the rotation ratio in FIG. 38 (b).

Therefore, it can be seen that the rotation ratio varies depending on the position of the second planetary gear 104.

In the prior art, the chain 105 is used in place of the ring gear 106 in the double pinion planetary gear device as shown in FIG. 38 (c). The driven second planetary gear 104D and the driven second planetary gear 104F of the driven unit are joined together by a chain 105 having teeth.

Since the revolving radius around the driving first planetary gear 103D and the revolving radius around the driving second planetary gear 104D change while rotating, the chain of the driving unit D engaged with the driving second planetary gear 104D ( As the radius of 105 is continuously changed, the rotational speed of the chain 105 of the driving unit D is changed, and the driven second planetary gear 104F of the driven unit F is driven from the engaged chain 105. Driven by (D), the driven second planetary gear 104F is engaged with the driven first planetary gear 103F and rotates on the driven second planetary gear shaft 107F while rotating the driven first planetary gear 103F. To rotate the circumference of the driven, and follow the second planetary planetary gear when rotating around the driven first planetary gear (103F) Since air (104F), the peripheral sides of the orbiting radius is the radius of the second planetary gear driven chain (105) of the follower (F) which is engaged on the periphery of (104F) is changed continuously is shifting.

In the present invention, the shifting system is classified into four types of shifting system (I), shifting system (II), shifting system (III), and shifting system (IV). Four examples of continuously variable transmission systems Nos. 1 to 4 are given, and one continuous transmission system (No. 1) will be described as a specific embodiment for easier understanding.

Shifting system

The above-described shifting system has a specification of a chain or belt in which the first planetary gear 103 or the second planetary gear 104 is engaged with the second planetary gear 104 depending on whether the step or long pinion, that is, the single-row pinion type, and Since the transmission ratio width can be varied, the present invention is classified into a shift system (I), a shift system (II), a shift system (III), and a shift system (IV) and described with reference to FIGS. 1 to 5 of the present application. do.

Referring to the shifting system I in FIG. 1, the configuration eliminates the ring gear in the double pinion planetary gear device and engages the chain 105 or belt with teeth as a substitute for the second planetary gear 104. FIG.

The main components are the sun gear shaft 101S, the sun gear 101, the carrier shaft 102S, the first planetary gear 103, the second planetary gear 104, the second planetary gear shaft 107, and the left carrier 102L. ), The right carrier 102R, the carrier gear 109, the output gear 111, the chain 105, where the carrier shaft 102S, the first planetary gear 103, the second planetary gear ( 104, the second planetary gear shaft 107 is composed of a plurality of pairs. In addition, in the shifting system of the present invention, the chain 105 or the belt has a tooth, and is configured such that the radius can be changed without rotation.

First, referring to the power transmission process, in the continuously variable transmission apparatus of the present invention, since the input and output of the power can be used differently in the same configuration, the power transmission path can be divided into the following two cases.

Case 1 is a case where the chain 105 is stopped, power is input to the sun gear shaft 101S, and output is output from the output gear 111 engaged with the carrier gear 109.

Case 2 is a case where the chain 105 is stopped, power is input from the output gear 111 engaged with the carrier gear 109, and output from the sun gear shaft 101S.

In the above case 1 is applied to the embodiment of the present invention as shown in Figure 1, looking at the power transmission process as follows.

When the power is input to the sun gear shaft 101S and the sun gear shaft 101S is rotated, the first planetary oil assembled with the sun gear shaft 101S and the spline and the fixed sun gear 101 rotates and meshes with the sun gear 101. The gear 103 rotates on the carrier shaft 102S, and the second planetary gear 104 engaged with the first planetary gear 103 rotates on the second planetary gear shaft 107.

Since the chain 105 engaged with the second planetary gear 104 does not rotate, the left carrier 102L, the right carrier 102R, and the carrier gear 109 revolve around the sun gear 101, and the carrier gear is rotated. The output gear 111 meshed with 109 is output.

In the case 2 with reference to Figure 1, looking at the power transmission process as follows.

When the power is input to the output gear 111 and the output gear 111 rotates, the carrier gear 109 meshed with the output gear 111 rotates and the chain 105 meshes with the second planetary gear 104. ) Does not rotate, so the left carrier 102L and the right carrier 102R revolve around the sun gear 101, and the second planetary gear 104 meshes with the first planetary gear 103 to rotate. 1 The planetary gear 103 and the sun gear 101 are engaged and rotated, and are output from the sun gear shaft 101S integrated with the sun gear 101.

Next, the shift principle will be described with reference to Figs.

Since the shift principle of the present invention is the same regardless of the power transmission path, looking at the shift principle according to the case 1 of the power transmission method,

When the engine power is input to the sun gear shaft 101S and the sun gear 101 is rotated, the first planetary gear 103 engaged with the sun gear 101 rotates on the carrier shaft 102S, and the first planetary gear ( The second planetary gear 104 engaged with 103 rotates on the second planetary gear shaft 107 and corresponds to the right carrier 102R corresponding to the radius of the chain 105 that is engaged around the second planetary gear. While rotating around the sun gear 101, the rotational force is transmitted to the output gear 111 engaged with the carrier gear 109.

When the right carrier 102R rotates about the sun gear 101, not only the right carrier 102R but also the left carrier 102L, the carrier shaft 102S, the first planetary gear 103, the second planetary gear 104 ) And the like also rotate about the sun gear 101 at the same time.

Here, when the second planetary gear shaft 107 is continuously rotated by a predetermined angle about the center of the carrier shaft 102S, the second planetary gear 104 is engaged with the first planetary gear 103 in the first planetary gear. The gear 105 is revolved around, and the chain 105 engaged around the second planetary gear 104 does not rotate, but the radius of the chain 105 is continuously changed, where the radius of the chain 105 Is changed but does not rotate, so that the idle speed of the carrier 102 continuously changes and continuously shifts, thereby transferring the changed rotational force to the output gear 111 engaged with the carrier gear 109.

Looking at the shifting process, when the radius of the chain 105 engaged with the second planetary gear 104 around the second planetary gear 104 is the maximum, the rotational speed of the output carrier gear 109 becomes minimum. . At this time, the second planetary gear 104 rotating on the second planetary gear shaft 107 is revolved around the first planetary gear 103 by a predetermined angle, and the chain is engaged around the second planetary gear 104. If the radius of 105 is made small, the rotational speed of the output carrier gear 109 becomes large.

When the radius of the chain 105 engaged around the second planetary gear 104 is minimum, the rotation speed of the output carrier gear 109 is shifted to the maximum.

That is, when the radius of the chain 105 engaged around the second planetary gear 104 changes continuously, the rotation ratio of the sun gear 101 and the carrier gear 109 changes continuously. At this time, the chain 105 does not rotate, only the radius changes.

Next, with reference to FIG. 3, the shifting system II is demonstrated.

The difference from the shifting system I of FIG. 1 is that the second planetary gear 104 is formed by applying a multi-row pinion of a step or long pinion, and is not engaged with the second planetary gear 103. The chain 105 is engaged with the pinion in the left row.

Therefore, the characteristics of the shifting system II may vary the type of teeth (for example, roller chain, silent chain, etc.) of the chain 105 and the second planetary gear 104 engaged with the chain 105. It can be applied, and it is possible to widen the choice of conditions (e.g. pitch, number of teeth, etc.) that are limited in the design of the teeth.

The power transmission process and the shift principle of the shift system II are the same as the shift system I.

Next, the shift system III will be described with reference to FIG.

The configuration difference from the shifting system I of FIG. 1 is that the first planetary gear 103 is formed by applying a multi-pinion type pinion of a step or long pinion, and a sun gear is applied to the pinion in the right column of the first planetary gear 103. (101) is engaged, and the second planetary gear (104) is engaged with the pinion in the left column.

In addition, the functional difference with the shifting system I of FIG. 1 is as follows.

When the second planetary gear 104 revolves around the first planetary gear 103, interference with the sun gear 101 can be avoided, thereby making the rotation angle larger than that of the shifting system I.

Accordingly, the width ratio of the speed change ratio can be increased by increasing the radius ratio of the chain 105 meshed around the second planetary gear 104.

The power transmission process and shift principle of the shift system III are the same as the shift system I. FIG.

Next, with reference to Fig. 5, the shift system IV will be described.

In the shifting system III of FIG. 4, the second planetary gear 104 is formed by applying a multi-row pinion of a step or long pinion, and has both the shifting system II and the shifting system III. Therefore, compared with the transmission system I, the speed ratio width can be increased, and the tooth shape of the chain 105 and the second planetary gear 104 meshed with the chain 105 can be variously applied.

The shift principle of the shift system IV is the same as the shift system I. FIG.

Shifting adjustment system

In such a shift system, in order to obtain a continuous shift ratio, the second planetary gear 104 is orbited around the first planetary gear 103, and at least one of the plurality of second planetary gears 104 is always present. There is a need for a system that engages with the chain 105 and changes the radius so that the radius of the chain 105 is concentric. This system is called shift control system.

6 to 8, a shift adjustment system will be described.

When the adjustment input gear 201 is rotated, the adjustment main gear 202 engaged with the adjustment input gear 201 rotates, and the adjustment slider 233 assembled with the adjustment main gear 202 and splines integrally connected with each other is also included. Rotate

When the adjustment slider 233 moves in the left or right direction, the helical slider 234 also moves in the left or right direction. At this time, the adjustment thrust bearing 231 is provided so as not to disturb the rotation of each of the adjustment slider 233 and the helical slider 234.

The left carrier 102L connection portion of the helical slider 234 is machined with a spline (or spur gear), and the connection portion of the adjustment sun gear 204 of the helical slider 234 is machined with a screw (or helical gear), so that the helical slider ( The 234 moves in the left or right direction while rotating integrally with the left carrier 102L, and when the helical slider 234 moves in the left or right direction, the adjusting sun gear 204 assembled with a screw (or helical gear) Is rotated so that the left carrier 102L and the adjustment sun gear 204 are rotated.

When the adjusting sun gear 204 rotates, the flange gear 205 meshed with the adjusting sun gear 204 rotates. The flange 206 integrally connected to the flange gear 205 and the flange 207 are assembled and fixed by splines to the second planetary gear shaft 107. When the flange gear 205 rotates, the second planetary The second planetary gear 104 rotating on the gear shaft 107 is orbited around the first planetary gear 103 in engagement with the first planetary gear 103 to refer to the center of the sun gear shaft 101S. As a result, the center radius of the second planetary gear 104 is changed.

In response to the change of the radius, the radius of the chain 105 engaged with the second planetary gear 104 changes simultaneously. At this time, the chain 105 does not rotate, only the radius changes.

In addition, the adjustment input gear 201 and the guide cone gear 252 are engaged.

The guide cone adjusting shaft 256 is assembled with a spline and a guide cone gear 252, a left guide cone adjusting gear 255L and a right guide cone adjusting gear 255R, and are integrally connected to each other.

The left guide cone slider screw 254L is fixed to the left guide case 16, and the right guide cone slider screw 254R is fixed to the right case cover 11.

The inner diameter of the left guide cone slider 253L is machined and the outer diameter is geared, the screw of the inner diameter is assembled with the left guide cone slider screw 254L, and the gear of the outer diameter is combined with the left guide cone adjusting gear 255L. Are matched.

In operation, when the adjustment input gear 201 rotates, the guide cone gear 252 rotates, the left guide cone adjusting gear 255L and the right guide cone adjusting gear 255R rotate, and the left guide cone adjusting gear ( 255L) and the left guide cone slider 253L rotates on the left guide cone slider screw 254L in a left or right direction while rotating.

At the same time, the right guide cone slider 253R engaged with the right guide cone adjusting gear 255R rotates and reciprocates in the right or left direction on the right guide cone slider screw 254R.

When the left guide cone slider 253L moves in the right direction, the right guide cone slider 253R moves in the left direction, and when the left guide cone slider 253L moves in the left direction, the right guide cone slider 253R moves in the right direction. Done. That is, both guide cone sliders reciprocate in opposite directions.

The left guide cone 251L is assembled by a spline to the left case 13 so as to slide, and a thrust bearing 257 is inserted between the left guide cone slider 253L. The right guide cone 251R is assembled by a spline to the right case 12 so as to slide, and a thrust bearing 257 is inserted between the right guide cone slider 253R.

A chain 105 is installed between the left guide cone 251L and the right guide cone 251R to contact each guide cone on both sides of the chain 105.

When the left guide cone slider 253L moves to the right, the left guide cone 251L moves to the right, and at the same time, the right guide cone slider 253R moves to the left and the right guide cone slider 251R moves to the left. The width between the cones becomes narrower, and the chain 105 in contact between both guide cones does not rotate, but only the radius of the chain 105 becomes large.

In addition, when the left guide cone slider 253L moves to the left side, the left guide cone 251L moves to the left side, at the same time the right guide cone slider 253R moves to the right side, and the right guide cone 251R moves to the right side. , The radius of the chain 105 between both guide cones is small, and the width between both guide cones is large.

At this time, both guide cones move in the left or right direction without rotation, and the chain 105 does not rotate but only the size of the radius changes.
