Description

The present invention relates to a continuously variable transmission capable of generating a gear ratio using a biconical inner wall.

At present, various technologies related to continuously variable transmissions (CVT) using a traction drive mechanism in the drive system of various vehicles such as automobiles have been provided, and belt-type continuously variable transmissions include pulleys on the main drive side, A transmission belt is wound around a pulley on the driven side that is connected to an output shaft that transmits power to the wheels, and transmission loss due to friction between the pulleys and transmission of large torque such as large displacement cars and turbo cars. Is not suitable.

Japanese Patent No. 3381914 (Patent Document 1) has already been known as a method of performing two-stage transmission by connecting two cones with a chain, and connecting the two cones without loosening the chain; Therefore, a large space is required as compared with a continuously variable transmission (CVT) having a range of the same torque and the same gear ratio as [0002].

As another continuously variable transmission using two cones, there is a conical friction transmission type continuously variable transmission disclosed in Japanese Patent Application Laid-Open No. 2001-349404, and it is possible to improve the strong torque and durability, and to change the gear ratio quickly. Without placing the intermediate idler on the straight lines of both the conical master wheel and the inverted conical follower, the stress for pressing the two rollers against the two cones with the connecting rod and the convexity of the outer periphery of the cone and the intermediate idler Since the contact surfaces are few in shape, it is necessary to sandwich the two rollers with a large stress in order to prevent the two rollers from idling in order to prevent power loss.

Japanese Patent No. 3381914 JP 2001-349404 A

In view of the above-described background art, the present invention structurally solves the slip loss between the power transmission pulley and the belt of a continuously variable transmission (CVT) in the past, and generates the transmission ratio by the circumferential ratio of the inner walls of the two cones. In addition to the fact that the roller and cone through power transmission are in contact with each other in an uneven state, the contact area and contact pressure can be taken efficiently, and the power transmission efficiency and components are simplified by a simple structure. The object is to save space by reducing the number of points, and to control the shift and the shift speed with fine control by individually controlling the two rollers.

The bicone-type continuously variable transmission 1 according to the present invention has a bicone 2 shape in which two mortar-shaped bottom surfaces whose apex angles are cut can be joined and rotated, and the apex angle is cut into the cavity of the bicone 2. The power input side transmission shaft 3i and the power output side transmission shaft 3e are inserted through the openings, and the rollers 4i and 4e that move parallel to the respective shafts of the two transmission shafts 3i and 3e and do not run idle are passed through. The outer periphery of the rollers 4i, 4e is brought into contact with the inner wall surface of the double cone 2 to transmit power, and in addition to the guide rod 6 supporting the shift fork 5 sandwiching the rollers 4i, 4e, the rollers 4i, 4e A position sensor that measures the position of each of the two is provided, and the CPU calculates the appropriate gear ratio from the positions of the two rollers 4i and 4e, the rotational speed and torque of the power input, the operating state history of the prime mover, etc. Belt 7 and connecting rod 8 side toothed pulley 9 and actuator side toothed Ri 10 and by a shift fork 5 is movable by an external actuator to shift the roller 4i, the position of 4e each in the CPU control.

Further, a connecting rod 8 is arranged for the purpose of stabilizing the rotation of the two transmission shafts 3i, 3e and pressing the two rollers 4i, 4e against the inner wall surface of the bicone 2. The transmission shaft bearing 11 fitted to the connecting rod 8 is inserted into the two transmission shafts 3i, 3e, and the power input side and power are inserted near the ends of the two transmission shafts 3i, 3e. The two output-side shafts 11 on the output side are supported and bridged by the connecting rod 8, and the connecting rod 8 becomes free in the bicone 2.

Further, for the purpose of gripping the rollers 4i, 4e without sliding and slipping on the inner wall surface of the bicone cone 2, a pressure is applied to press the roller tire 25 of the rollers 4i, 4e further against the inner wall surface of the bicone cone 2. Therefore, there is also a means for providing the connecting rod 8 with a suspension device such as a compression spring 12 for causing the tip ends of the two transmission shafts 3i and 3e to face the inner wall surface of the double cone 2.

Further, the mountable actuator 15 is installed on the mountable shift fork 13, the mountable shift fork 13 is supported by the guide rod 14 with a rack for actuator control, and the mountable shift fork 13 is caused to idle in the vertical direction. By using means including a guide groove 17 for shift fork to be suppressed, a rack portion 18 for receiving a driving force from the pinion gear 16 of the mounted actuator 15, and an insertion port 19 for fixing to the connecting rod 8, a double cone is used. Space saving in 2 and more direct control of the rollers 4i and 4e are possible.

Considering the production of the present invention, in order to stabilize the rotation of the bicone 2 and simplify the design of the connecting rod 8, the equator of the bicone 2 is separated on the equator and joined by an equator tube 20, and the equator circle is connected. The outer periphery of the tube 20 is supported by a bearing, and the circular tube 21 for both ends is connected to the opening where the apex angle of the bicone 2 is cut, and a standard bearing is fitted around the outer periphery of the circular tube 21 for both ends. A means for receiving the rotation of the cone 2 can also be selected.

The power transmission belt that comes in contact with the pulleys of existing general continuously variable transmissions (CVTs) changes the power transmission and gear ratio while sliding the side of the belt sideways, reducing skid resistance, shifting speed and shifting Although it is difficult to increase the accuracy, the present invention has a feature that the outer circumferences of the rollers 4i and 4e and the inner wall surface of the bicone 2 are in contact with irregularities, so that the rollers 4i and 4e do not slip and keep a grip state. This is easier to implement than the background art.

As a feature of the biconical continuously variable transmission 1 of the present invention, a cone-shaped cone with the apex angle cut off is directly joined on the equator to form a biconical body. The possibility of unnecessary machine lubricating oil and the effect of reducing the number of parts are recognized.

The above-mentioned two prior art documents [0005] [Patent Document 1] Patent No. 338914 and [Patent Document 2] Japanese Patent Application Laid-Open No. 2001-349404 continuously variable transmission control a gear ratio with a single actuator. However, the bicone-type continuously variable transmission 1 of the present invention is controlled by two actuators, and has a skid resistance between the pulley and the transmission belt of the conventional continuously variable transmission (CVT) of [0002]. With a structural solution without relying on power transmission, you can expect even finer control with high-efficiency power transmission, accurate gear shifting, quick gear shifting speed, and so on.

The theoretical value of the output rotational speed (Re) of the biconical continuously variable transmission 1 of the present invention is shown in FIG. 7 with reference to the input rotational speed of Ri, the diameter d1 of the input side roller, and the bicone in contact with the input side roller. When the outer diameter D1 of the inner wall, the diameter d2 of the output side roller, the diameter D2 of the outer periphery of the bicone inner wall hitting the output side roller and the circumference ratio π,

The theoretical value for obtaining the minimum output rotation speed (Re-min) is shown in Fig. 7 (a). The input rotation speed of Ri and the input side roller diameter (d1min) are set to the conical inner wall maximum diameter part (D1min). Obtained by applying the diameter (d2min) to the cone inner wall minimum diameter part (D2min) and substituting it into [Equation 1]

The theoretical value for obtaining the maximum output rotation speed (Re-max) is shown in Fig. 7 (b). The input rotation speed of Ri and the input side roller diameter (d1max) are set to the cone inner wall minimum diameter part (D1max). It is obtained by applying the diameter (d2max) to the maximum conical inner wall diameter (D2max) and substituting it into [Equation 1]

The gear ratio (theoretical value) is obtained from the mathematical expressions of [Equation 2] and [Equation 3] derived from these. When showing the gear ratio,

BRIEF DESCRIPTION OF THE DRAWINGS Schematic of the decimal stage conical mixing type transmission which is an Example of this invention.

The shape of the bicone 2 of the bicone-type continuously variable transmission 1 of the present invention is a rotating body that constantly rotates when power is transmitted, so that it is required to be lightweight and compact. The method of fitting a non-standard bearing is considered to be the best, but the apex angle of the bicone 2 is cut, the circular tube 21 for both ends is joined, and the standard bearing is fitted, or a circular tube is attached to the inclined outer wall. One opening of the circular tube is connected to the outer wall of the bicone 2 in a fitting manner, and the part where the other circular tube and the outer wall of the bicone 2 are opened is reinforced with a member such as a washer. There is also a method of fitting a standard bearing into the outer periphery of the circular pipe.

Further, in order to maintain a rotational balance when rotating the rotating body of the bicone 2 at high speed, the equator of the bicone 2 is separated and the equator tube 20 is joined, and a bearing is provided on the outer periphery of the equator tube 20. There is also a configuration in which the bicone 2 is supported by a total of three bearings in combination with the bearings and two standard bearings described in [0024].

Two rollers 4i, 4e, etc., as means for discharging the dust generated in the bicone 2 are provided with a discharge port 22 for discharging the dust near the equator of the bicone 2, and the rotation balance of the bicone 2 is adjusted. I want to consider installing it while considering it.

By forming a cylindrical shape near the equator with the circular tube 20 for the equator, the connecting rod 8 for passing the two transmission shafts 3i and 3e can be easily designed and the layout of the compression spring 12 and the like described in [0009] can be easily achieved. From another point of view, it is necessary to consider the balance of moment of inertia and the like because the weight of the bicone 2 that is a rotating body that rotates constantly is increased by providing the equator circular tube 20. is there.

The rollers 4i and 4e for transmitting the power between the transmission shafts 3i and 3e and the bicone 2 are preferably provided with a plurality of roller pins 23 in order to support a large torque from the transmission shaft 3i3e. In order to facilitate parallel movement along the axes of the shafts 3i and 3e, it is also considered to arrange a bearing on the roller pin 23. A grip state such as rubber is provided on the outer periphery of the roller metal portion 24 of the rollers 4i and 4e. It is demanded that the roller tire 25 that is easy to maintain is worn and that the inner wall of the bicone cone 2 is gripped and that the transmission shafts 3i and 3e are easily translated on the axes.

The transmission shafts 3i and 3e are provided with a guide shaft guide groove portion 26 for guiding the roller pins 23 of the rollers 4i and 4e, so that the roller tire 25 exhibits the required performance. I want to select an appropriate material.

In order to facilitate the assembly of the biconical continuously variable transmission 1 according to the present invention, the equator vicinity of the bicone 2 can be separated, and the rollers 4i and 4e are inserted into the transmission shafts 3i and 3e, so that transmission shaft bearings are press-fitted. There is also an assembling method in which the transmission shaft bearing 11 is press-fitted into the portion 27 and assembled so as to be supported and bridged by the connecting rod 8, and then the mortars of the bicone 2 are joined together.

In addition to striving to stabilize the rotation of the transmission shafts 3i, 3e, in order to keep the rollers 4i, 4e slipping further to the inner wall surface of the bicone 2 and keeping them firmly gripped, the transmission shafts 3i, 3e There is also a method in which a suspension device such as a compression spring 12 that applies pressure to the inner wall surface 2 is installed on the connecting rod 8.

A guide rod 6 is disposed between the connecting rod 8 and the shaft 4i without shifting the rollers 4i, 4e between the shift forks 5 for shifting and without causing the shift forks 5 to idle in the vertical direction. In order to control the position of the shift fork 5 by connecting with the external fixing portion of the opening near the apex angle of the bicone 2, two external actuators are provided outside the opening where the two apex angles of the bicone 2 are cut. The actuator-side toothed pulley 10 and the connecting rod-side toothed pulley 9 which is also rotatable on the connecting rod 8 are attached to the external actuator, and the toothed belt 7 is hooked on the shift fork 5. The roller 4i, 4e is controlled via the shift fork 5 by the external actuator.

In the description of [0032] when moving the shift fork 5, the guide bar 6 and the function related to the actuator control are separately shown. However, in practical mass production, the mounted actuator 15 is replaced with the actuator mounted shift fork. The rack is provided with a pinion gear 16 disposed on the mountable actuator 15 and provided with a shift fork guide groove 17 for guiding the mountable shift fork 13 and a rack 18 as a receiving portion of the pinion portion 16. By using the attached guide rod 14, it is considered to be suitable for practical mass production to have two roles of guiding the mounted shift fork 13 and controlling the mounted actuator 15.

The adoption of the guide-equipped rack bar 14 allows the external actuator to be accommodated in the cavity of the double cone 2 mainly to omit the connecting rod side toothed pulley 9 and the toothed belt 7, Since the on-board actuator 15 is directly installed and moved by the rack and pinion mechanism, more direct control is possible. In addition, it is important to save space in the vicinity of the opening of the cut apex of the bicone 2, and the size of the entire bicone 2 that rotates continuously in the bicone type continuously variable transmission 1 of the present invention is important. Give a good fit.

As a method for determining and controlling the gear ratio, the positions of the rollers 4i and 4e from the position sensor for measuring the positions of the rollers 4i and 4e mounted at appropriate positions in the bicone 2 and the rotational speed and torque of the prime mover, etc. In addition to the intention of the driver who operates the sensors and the motor, the CPU considers the driving tendency and the design safety of various devices including the present invention. By changing the rollers 4i, 4e via the mounted shift fork 13, the gear ratio is changed while being pressed against the inner wall surface of the bicone 2.

As an embodiment for generating the gear ratio of the bicone-type continuously variable transmission 1 of the present invention, by changing the height of two mortars of the bicone, and in some cases, changing the outer circumference of the equator, the output characteristics of the application and the motor And can be implemented in the same way as the difference between the gear transmission near the pedal of a sports bicycle and the gear transmission near the rear tire and the number of gears, and the output side roller 4e and the transmission shaft. 3e can set the design load assumed to be lower than that of the input side roller 4i and the transmission shaft 3i. By changing each of the two input / output rollers 4i, 4e and the transmission shafts 3i, 3e, Space saving and weight reduction can be further achieved. As a result, a flexible gear ratio can be generated as shown in the equation [4] of [0022].

In order to stabilize and reinforce the rigidity of the connection rod 8, the guide rod 6 or the components in the vicinity of the guide rod 14 with rack and the rigidity reinforcement, the guide rod 6 or the guide rod 14 with rack and the connection rod 8 are arranged at three points. By arranging the connecting part 28 to be connected in step S2, there is an effect of stability and rigidity reinforcement with respect to vibration or the like of parts near the connecting part 28. A manufacturing method in which a notch into which the width of the connecting rod 8 fits is inserted in the front of the connecting part 28 (rod), and is fitted into a predetermined portion of the connecting rod 8, and the connecting rod 8 and the connecting part 28 (rod) are welded. Is

As an example of further strengthening the rigidity and rigidity, it is not the use of the structural advantage unique to the arch bridge of the bridge over the river, but it is separated by the bridge girder of the arch bridge, and the shore of the arch bridge is reversed back to back When the plate surface of the connecting rod 8 and the road surface portion of the arch bridge are vertically joined together, the road surface portion is placed on the center line of the road surface with the guide rod 6 or the guide rod 14 with a rack, the transmission shaft 3i, 3e is arranged, and the width of the arch bridge is narrowed by the size of the opening in the vicinity of the cut apex angle of the bicone 2 and connected to the external fixing part.

When one end of the guide rod 6 or the guide rod with rack 14 is fitted and fixed to the connecting rod 8 to be joined to the shore portion of the arch bridge, and the opposite end is connected and fixed to the external fixing portion, the cable portion of the cable-stayed bridge The cable of the cable-stayed bridge is generally assumed to have only a tensile stress, but the guide rod 6 or the guide rod with rack 14 employs a metal rod. In addition, it is possible to cope with compressive stress and torsional stress, and it is considered that the rigidity of the entire fixed part including the inside of the cavity of the biconical continuously variable transmission 1 can be considerably increased.

An inner bicone 28 having a shape close to a bicone fixed near the apex is arranged in the cavity of the bicone 2 of the bicone continuously variable transmission 1 within a range in which the bicone 2 can rotate, An inner opening 28 for fixing the vicinity of both ends of the guide bar 6 or the guide bar 14 with a rack is provided by cutting out a functional part in which the shape of the inner bicone 28 is movable.

In the case of adopting the inner bicone 28 method, it is considered that the countermeasures against vibration and the like of all parts including the still life part in the cavity of the bicone 2 and the effect of rigidity reinforcement are great, In addition to bringing out the proper performance and accurate operation of the movable parts inside, the inner bicone 28 does not need to be as high as the material selected for the rotating body and the movable parts, and is made of a material other than metal (synthetic resin). However, with respect to the shape of the inner bicone 28, since the bicone 2 and the rollers 4i and 4e also operate to rotate at high speed, the air generated in the cavity of the bicone 2 I want to make a design that takes into account the motor action. Further, in terms of practical mass production, since it is possible to manufacture with a mold, it is possible to foresee a simpler and cheaper manufacturing than the method of manufacturing and combining a plurality of parts in [Example 3].

An insertion hole 31 for inserting a transmission bearing fixing part 30 having a fitting opening for the transmission shaft bearing 11 is provided in the inner bicone 28, and the transmission bearing fixing part 30 can rotate the power transmission shafts 3i and 3e. A suspension device such as a compression spring 32 that presses against the inner wall of the cone 2 is inserted into the insertion hole 31 of the inner double cone 28, and the transmission bearing fixing component 30 is inserted into the insertion hole so as to sandwich the suspension device such as the compression spring 32. By inserting the roller 4i, the roller 4i, 4e can continue to apply an appropriate pressure to the inner wall of the bicone 2, and the roller 4i, 4e can maintain a firm grip and transmit power efficiently. Long-time operation is possible.

The two rollers 4i, 4e in the bicone 2 cavity for power transmission of the biconical continuously variable transmission 1 of the present invention are arranged on the shafts of two transmission shafts 3i, 3e as shown in FIG. 9 (a). 9 (b) shows an example in which a right / left angle θ is given from the vertical, and the two rollers 4i, 4e are moved up / down / left / right. I want to improve the transmission efficiency and transmission efficiency more finely and smoothly by giving the angle.

In addition, by making the roller tires 25 of the rollers 4i and 4e convex, and by devising such means as decentering the top of the convex, it can be combined with [0043] to make the shift and transmission more delicate and smooth. I want to study the improvement of efficiency.

Considering further space saving and simplification of the mechanism based on the bicone-type continuously variable transmission 1 of the present invention, as an example of implementation, a step is formed on one of the two cones of a bicone as shown in the schematic diagram of FIG. It is also possible to implement a small-number-stage conical mixed transmission 33 that combines a shift by the meshing method of the inner gear and the spur gear on the inner wall side and a shift using the inner cone wall of the present invention. As the gear, a helical gear or a helical gear is selected, and in addition to selecting a general method as a shift method, the small-number conical mixed transmission 33 is an electromagnetic method because it can be realized with a small number of steps. The implementation of is also interesting.

The small-number cone conical transmission 33 can be handled by a single gear in addition to a sense of acceleration that gives the driver a good impression similar to kickdown of a typical automatic transmission of an automobile. Since the range is large, it is possible to eliminate small shift shocks that generally give a negative impression to the driver. Further, it is also easy to embed a reverse gear (back gear) of the vehicle, which is difficult to achieve with the biconical continuously variable transmission 1 in terms of structure and overall space.

The place where the small number of gears of the small number stage conical mixed transmission 33 meshes generally requires transmission circulating oil. Therefore, an oil seal or the like is used to prevent oil leakage on the power input transmission shaft, etc. It is considered that it is necessary to provide the oil partition wall 34 between the cone portion of the small-number cone conical transmission.

When the bicone-type continuously variable transmission 1 of the present invention is used in an automobile, the FR (front engine rear drive) type is convenient in terms of layout. In order from the front of the automobile, there is also the possibility of using an engine, a bicone-type continuously variable transmission of the present invention, a clutch, a reverse motor (also an alternator), a rear differential, and a rear wheel drive wheel. When the engine is temporarily stopped (idling stop function), the type continuously variable transmission 1 itself has a flywheel function, and the reverse motor also serves as an alternator to increase the total power generation. In addition to the power for operating the equipment such as air conditioners), the possibility of use for forward travel at low speeds by rotating the reverse motor in reverse is also desired. (Hybrid car)

The transmission ratio required for a transmission of an engine-equipped motorcycle (hereinafter referred to as a motorcycle) is about 3 for a small displacement vehicle, about 2.2 for a medium displacement vehicle (about 400cc), and about 2.2 for a large displacement vehicle (about 1000cc). Since the speed ratio is about 2, the gear ratio is substituted into [0022] [Formula 4], and the diameter (D) of the inner wall near the apex angle of the bicone continuously variable transmission of the present invention is assumed to be 100 mm. Even so, as an example, it is a calculation that fits the horizontal width of the horizontal counter engine of a motorcycle made by BMW in Germany, but considering the space saving, it is also a consideration to make the size of the two mortars of the bicone different . However, since most conventional motorcycles have a crankshaft axis and a drive wheel axis that are parallel to each other, if the size of the two cones of the bicone is different, the mechanical power transmission flow is established. The difficulties are inherent.

When the bicone-type continuously variable transmission 1 of the present invention is used on a motorcycle, the vehicle reverse function (back function) is generally unnecessary, and the drive wheel suddenly stops rotating for some reason. When the double cone type continuously variable transmission is used, the gear ratio at the time of re-running is uncertain and re-running may be impossible. The biconical continuously variable transmission and the reverse motor are laid out. However, when used in the motorcycle, after the center stand for the motorcycle is hung, the engine is started to start the biconical continuously variable. Since the two input / output side rollers 4i and 4e of the transmission 1 can be returned to the fixed positions, it is considered that a conventional clutch system for motorcycles can be used.

Moreover, the use of the small-stage conical mixed transmission 33 of [Embodiment 6] from a vehicle with a strong hobby factor such as a motorcycle is also interesting, with a kick-down (used in automobile automatic) and a conical part in a small-stage gear transmission. In combination with the continuously variable transmission control, there is a high possibility that gear shifting from the normal engine speed to the engine speed (power band) where the engine performance can be maximized can be performed accurately. The throttle opening after being urged to prepare for quick acceleration is exhilarating.
