Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmission capable of continuously changing the rotation transmitted from a prime mover.

[0002]

2. Description of the Related Art As a conventional continuously variable transmission, a belt type, a semi-curved surface type, or a flat contact type continuously variable transmission method in which free rotation is limited by a spherical shape is known.

The disclosed prior art is disclosed in Japanese Patent Application Laid-Open No. Hei 8-24.
7244, or a toroidal CVT (semi-curved surface continuously variable transmission) such as Japanese Patent Application Laid-Open No. 62-233556, and NHK Special "Across the Century: The Wall of Friction" broadcast on August 20, 2000 as a reference case. Breaks the Toroidal CVT
According to the 1977 report of the United States in 1977, "Energy Conservation Strategy by Friction Control," friction consumes two-thirds of the energy consumed by automobiles in the United States. -4.5% of-
It is reported that about 445 million drums can be saved.

[0004]

A belt-type continuously variable transmission is constituted by a pair of openable and closable drums. Each of the drums is linked by a single belt, and each of the drums is opened and closed by pressing and releasing. The gear ratio is varied by alternately changing the outer diameter of the belt, but there is a limit to the torque transmission force for high torque transmission due to friction between the belt and the drum.

[0005] Further, a continuously variable transmission with a spherical contact and a point contact, for example, a rotation in which one rotating body (hereinafter referred to as a "transmission portion") and a rotating shaft for restricting free rotation are installed in Fig. 1 of JP-A-8-247244. The figure shows a method in which a rotating shaft and a transmission unit are used for driving or driven, and one side of the transmission unit is interlocked by a spherical pressure rotation by using a rotating shaft and a transmission unit. Restricts the free rotation of the entire spherical surface and restricts the setting of the gear ratio, and cannot use the entire spherical surface as an interlocking contact point.

[0006] Compared with the present invention, there is no moving device necessary for shifting the contact-coupled sphere by linear movement, and furthermore, the operation of the continuously variable device requires a rotating shaft and a transmission unit installed in a sphere. A rotation interlocking device and a linear moving device for moving,
It is necessary to perform interlocking connection and movement synchronization control by a combination of each device such as a rotation interlocking device and a straight moving device on the driving side and the driven side of the transmission unit. This is an element that hinders the spread of machines.

When the sphere reaches the position where the maximum speed ratio (maximum torque) is generated, that is, at the moment when the sphere that rotates in contact with the transmission is released from the contact rotation pressure of the transmission,
A repulsive action occurs where the transmission and the sphere try to separate from each other,
This causes a slight swing between the transmission and the sphere,
This slight rocking causes wear of the shaft fitting portion between the shaft of the transmission portion and the bearing portion with the passage of time, causing poor spherical interlocking of the transmission portion with the spherical portion. The development of a stabilizer required to maintain stable rotation to prevent failure is expected, and the numerical value of the torque transmission force of this transmission method is such that a single spherical contact is moved on the contact surface of the transmission section. One point is the numerical value of the torque transmission force. The development of a point-contact continuously variable transmission that has a strong torque transmission force capable of increasing this value (contact point) to enable continuous gear shifting and that can be used for a wide range of applications is expected.

In the toroidal CVT, the speed change portions of the input member and the output member are formed by a pair of semi-curved surfaces facing each other, and the base portions of the speed change portions are aligned with each other to rotate.
In addition, the interlocking method is such that the vertical rotation of the partially curved rolling member for slidingly interlocking each transmission portion is interlocked by a circular motion obtained by converting the rotation by 90 degrees, and the rolling member and the semi-curved transmission portion are horizontally and vertically interposed. The intersecting point is used as a contact point, and the contact surfaces of a pair of semi-curved surfaces are alternately continuously slid between circles drawn by the tangent line of the rolling member to continuously change the speed by interlocking the contact friction. The production of semi-curved surfaces that require high precision requires a high degree of precision machining technology. Compared with the flat type transmission unit of the present invention, a transmission unit using a semi-curved surface has a gear ratio of 1: 1 when interlocking. Only the base line of the transmission unit and the tangent of the rolling member are parallel and linked, and at other tangential positions, the parallel of the base axis of the transmission unit and the tangent of the rolling member breaks down. It is necessary to increase the angle between the shaft and the base axis. There for greater action to push the rolling member from the contact point when the tangent of the angle increases, also must match the base shaft line of the shifting portion always accurate,

Further, when a large torque or a large transmission ratio is required, a plurality of pairs of semi-curved transmission parts must be connected and increased, and the additional connection requires the same number of rolling members to be increased. Increased control of rolling members requires precise tuning control, and additional connection of the transmission section increases weight and deteriorates fuel efficiency, and it is necessary to maintain and manage accuracy over a long period of use. It becomes.

[0010]

In order to achieve the above object, in a continuously variable transmission according to the present invention, as shown in FIG. 1, first and second geared transmissions 2, 5 and a plurality of third transmissions are provided. The contact surface of the geared transmission unit 7 (the surface that slides on the rolling member 8 and interlocks with the speed change) is formed of a flat surface, and the first, second, and third geared transmission units 2, 5, and 7 are engaged with the gears. And the rolling members 8 are formed as spheres or discs (not shown), and the geared transmission portions 2 are opposed to each other. , 5 and 7 are provided with a certain distance between the rolling member 8 and the lubricating oil so as to be slidable.
The rolling member 8 is slidably mounted on the moving device 11 and the rolling member 8 is interposed between the first and second geared transmission units 2 and 5 and the plurality of third geared transmission units 7 at opposing intervals. The torque can be transmitted by the action of friction caused by the contact between the member 8 and the lubricating oil and the gears of the first and second geared transmission units 2 and 5 and the plurality of third geared transmission units 7. The following effects can be obtained by using a moving device that reciprocates straight. That is, a plurality of rolling members 8 loaded by operating the moving device 9 provided in one moving device slide on each of the contact surfaces facing each other at the same time, so that the contact position can be reliably and easily changed.

Further, the moving device 9 for moving the first moving device 11 is either a rotation interlocking by gear interlocking with a gear of a moving motor having an interlocking gear connected by screwing a screw, or a hydraulic piston hydraulic pressure. (Not shown)
Also, a rotation stopper 10 for preventing rotation of the first moving device 9 due to screwing rotation is penetrated through the first moving device 11 to serve as a guide,
Alternatively, either a concave portion or a convex portion is installed (not shown) in each of the contact portions inside the first box 12 and outside the first moving device 11 and fitted and slid.

As described above, the first and second geared transmissions 2, 5 and the plurality of third geared transmissions 7, which are gear-coupled via the rolling member 8 loaded in the first moving device 11, are rotated. The continuously variable speed can be changed by sliding with the moving member 8,

The operation of the speed change is such that one of the two contacts of the rolling member 8 slidingly contacting the respective contact surfaces facing each other draws a circle on the contact surface and a circle draws the other contact on the contact surface. Is changed by the interlocking movement of the rolling member 8,
The ratio of the size of the two circles is the ratio of the rotational speed of each transmission section,
Gear ratio.

That is, in the present continuously variable transmission using one side of the contact surface, the rotational force transmitted from the prime mover rotates a plurality of third geared transmission units 7 gear-linked with the first geared transmission unit 2. The rotation is transmitted to the rolling member 8 that contacts the contact surface of the first geared transmission, and the rotation is transmitted to the second geared transmission 5 that is linked at the same time as the rolling member 8 makes a rotational movement, and further gear-linked. The third geared transmission 7 is rotated and interlocked to transmit torque. When the loaded rolling member 8 is linearly moved by the first moving device 11 from a set position near the center of the first geared transmission 2 to a set position outside, the second geared transmission 5 is moved. The contact position also moves from the set outside position to the set position near the center,
The rolling member 8 slides between the first and second geared transmission units 2 and 5 and the plurality of third geared transmission units 7 in opposition to each other to generate a gear ratio, and a plurality of third transmission units. The magnitude of the torque transmitting force can be determined by increasing or decreasing the number of combinations of the geared transmission unit 7.

FIG. 3 shows a second input shaft 13 and a second input shaft 13.
The first gear 15 provided on the shaft portion of the output shaft 14 and the second gear 17 provided on the shaft portions of the plurality of first transmission portions 16 are gear-linked,
Torque can be transmitted by the sliding interlock of the rolling member 8 loaded in the second moving device 18, and the torque transmitting force is changed from low torque to high torque by increasing or decreasing the number of combinations of the gear interlock of the first gear 15 and the plurality of second gears 17. Can be transmitted to

Further, the swing described in the item [0007], that is, the slight swing between the contact surfaces of the first, second and third geared transmissions 2, 5, and 7 and the rolling member 8 is performed. As shown in FIG. 4, one to three sets of the stabilizers 29 to prevent the rocking of the lower rolling member on the opposite side (upper side of the center of the base axis) about the base axis of the transmission portion. The necessary number is arranged at the necessary position where the movement is minimized, and the interval between the contact positions is adjusted by rotating the adjustment screw 22 attached or by the repulsive force of the spring (not shown). The ball or roller is attached to each box so that the position can be adjusted, and the ball or roller that contacts each contact surface is mounted on the stabilizer 29.
The rotation of the roller can reduce the contact resistance with each speed change portion, and can reduce the swing of the rolling member 8 and each speed change portion. Prevents abrasion caused by swinging of the mating part, and maintains the parallel contact surfaces facing each other to reduce poor contact due to one-sided receiving when the rolling member 8 moves, thereby ensuring stable rotation of the transmission part and reliable shifting. Interlock is obtained.

Further, when the impact balls 36 are attached to the contact portion between each transmission section and each box in a circumferentially continuous manner or at equal intervals, smooth operation with less contact resistance and an effect of reducing abrasion can be obtained. The durability is improved.

Further, when DM2H, a product of Idemitsu Kosan Co., Ltd., is used for the lubricating oil of this device, the following properties can be used.
That is, when lubricating oil enters the contact portions between the first and second geared transmission units 2 and 5 and the plurality of third geared transmission units 7 and the rolling members 8, contact pressure is applied and the molecules of the lubricating oil are instantaneously combined. In addition to increasing the friction between the contact surfaces of the first and second geared transmissions 2 and 5 and the plurality of third geared transmissions 7 and the rolling member, the contact portion is formed by the rotation of the rolling member 8. When the gear moves, the pressure is released and the connection of the molecules of the lubricating oil can be released instantaneously, and the rolling member 8 comprises the first and second geared transmissions 2 and 5 and the plurality of third geared transmissions 7 respectively. Can be efficiently linked to transmit torque. A contact pressure of about 6 tons is applied to the contact between each contact surface and the rolling member 8, and this pressure is applied to a combination of carbon bearing steel (SUJ2) or high-purity high-rigidity steel made of Sanyo Special Steel and lubricating oil. Thereby, the effect of preventing the metal from being peeled off at the contact portion due to the frictional pressure between the contact surface and the contact point of the rolling member 8 or the destruction of the main body and the improvement of the durability can be expected, and the practical application is facilitated.

Furthermore, as compared with the toroidal CVT, the present invention provides a first and second geared transmission unit 2, as shown in FIG.
5 is maintained in parallel, and one side of the contact surface of each transmission unit is brought into contact with the contact point of the rolling member 8, that is, the contact surfaces of the first and second geared transmission units 2, 5. And the tangents of the rolling members 8 are substantially perpendicular to each other, so that the base axes of the first and second geared transmissions 2 and 5 and the plurality of third geared transmissions 7 and the tangents of the rolling members 8 are in contact with each other. Even if the moving member 8 moves, the parallelism is always maintained and a high contact efficiency can be maintained. Further, each of the first and second geared transmission units 2 and 5 and the plurality of third geared transmission units 7 is a box due to a processing error. Even if the installation position shifts, the structure does not easily affect the contact accuracy between the parallel and the flat surface, making it easy to manufacture and process. The circle drawn by the contact point of the rolling member 8 on the contact surface can be reduced to near the center without difficulty. The speed part is made up of a plane with a constant thickness, so that it is easy to maintain strength. Also, by increasing the outer diameter of the transmission part and the moving amount of the moving device, the gear ratio can be increased and a high pressure contact force (torque transmission force) can be easily achieved. Are obtained continuously.
