Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention considers gear connection driving between an input side and an output side in a planetary gear configuration,
A device that does not use a clutch or the like to drive the input side in the input direction due to the rotation of the output side, and stops the drive in the input side in the input direction irrespective of each rotation range on the output side. Related to linked drive and automatic continuously variable transmission.

[0002]

2. Description of the Related Art In a continuously variable transmission having a conventional planetary gear configuration, each gear is locked or a free output is driven up.

[0003]

In a conventional continuously variable transmission having a planetary gear structure, the output side and the input side are always connected by a gear, so that the input by the rotational force on the output side is required. The drive in the input direction on the output side is inevitable, and there is a problem that the output side must be continuously variable driven with a gear ratio equivalent to the square of the input side rotation speed.

[0004] The present invention is applicable to any rotation range on the output side.
The purpose is to obtain the stop state of the drive from the output side to the input side and to the input side, and at the same time, to obtain a large differential by revolving the planetary gear in the reverse direction of the input. The purpose is to perform variable drive on the output side by number, and to obtain an automatic continuously variable transmission by providing a self-driven method using the output side rotational force of the device.

[0005]

In order to achieve the above-mentioned object, the present invention provides an input-side input-direction drive control apparatus for obtaining an automatic continuously variable transmission with a planetary gear.
The ring gear in the planetary gear configuration is used as the input side and the sun gear is used as the output side. The planetary gear uses a planetary gear that integrates large and small gears. The large gear meshes with the ring gear and the small gear meshes with the sun gear. At the same time, a guide ring gear for revolving the planetary gear in the reverse direction of the input is provided and meshed with the small gear.

The gear diameters of both the small gear meshing with the guide ring gear and the large gear meshing with the ring gear on the input side, that is, the planetary gear integrated with the large and small gears, are 1: 2.
A guide ring gear for revolving the planetary gear in the reverse direction to the input is driven in the reverse direction to the input.
This is effective for the reasons described below.

The fact that the gear diameters of both the planetary gears are set to a ratio of 1: 2 means that the planetary gears mesh with the guide ring gears to rotate in the input direction and revolve in the reverse direction of the input. By applying a large gear, it is easy to rotate the planetary gear in the input direction by the ring gear. If the difference in gear diameter is large, the drive width of the guide ring gear in the reverse direction of the input is increased. I have to take it.

For the above-described reason, when the input is turned off while the output side is rotating, the planetary gear rotates by the reverse rotation of the input and the rotation in the input direction by the small gear of the planetary gear meshing with the guide ring gear. For one rotation,
The value (distance) obtained by subtracting the small gear diameter from the large gear diameter of the large and small gear-integrated planetary gears and multiplying by the pi is calculated in the input direction of the input side ring gear meshing with the large gear of the planetary gear. The driving action works.

The input-side ring gear driven in the input direction by the above-described gear configuration also has a smaller gear diameter than the large gear diameter of the planetary gear integrated with the large and small gears for one rotation of the planetary gear. When the guide ring gear that meshes with the small gear of the planetary gear is driven in the input reverse direction by the value (distance) obtained by multiplying the pi by subtracting, the force that drives the input ring gear in the input reverse direction acts.

For the above reason, the driving distance in the input direction of the input side ring gear by the large gear rotating around the center of the gear shaft of the planetary gear and the guide ring gear meshing with the small gear of the planetary gear are changed by the rotation of the planetary gear. In response to the rotation, the planetary gear that rotates and revolves in the input reverse direction is driven by the input reverse direction by the value (distance) obtained by multiplying the large gear diameter of the planetary gear by the small gear diameter and multiplying by the pi. Due to the action of the pulling action, the distribution of the driving distance by pulling the ring gear meshing with the planetary gear in the opposite direction to the input becomes almost equal, that is, the driving action in the input direction of the input side ring gear in all rotation ranges on the output side is stopped. Obtain the state.

The purpose of performing the revolving drive in the reverse direction of the input by the ring gear and the input of the planetary gear and the same input and reverse drive of the planetary gear support frame is to input the same rotation on the input side of the conventional planetary gear directly connected to the gear. The planetary gear revolution and the driving of the planetary gear support frame transmit power in a state where the input side always follows the rotation on the output side. The output side must be driven, but the planetary gear revolves in the direction opposite to the input side and driven by the planetary gear support frame of the present invention, so that the output side is always repelled in order to reversely drive the output side with respect to the input. The power is transmitted at, that is, the differential effect works due to the opposite rotation, and the stepless variable action on the output side is obtained.

By obtaining the input-direction drive stop state from the output side of the input side ring gear as described above, the output side can be driven by the input at a constant rotation on the input side in all rotation ranges on the output side. And the differential function of the planetary gear input reverse revolving drive can provide the function of changing the gear ratio of the planetary gear configuration directly connected to the gears. Power transmission with variable gear ratio To get an automatic continuously variable transmission.

The guide ring gear of the above device can be driven in the reverse direction of the input by using other powers.
By using the planetary gear rotation by input and the sun gear driving force by orbital drive, it is easy to move the guide ring gear in the opposite direction to the input simultaneously with the input. There is a method.

In each of the three connection driving methods of the above-mentioned device, a new planetary gear with large and small gears is provided, and a planetary gear on the control side is used for discrimination from the planetary gear. Engage the sun gear, and apply for Japanese Patent Application No. Hei 8-
No. 27250, in which the self-reversing driving force of the sun gear in the self-reversing driving of the sun gear is applied to drive the planetary gear on the control side and move the guide ring gear by itself. The connection method with the ring gear can drive the guide ring gear in the input reverse direction by three different connection means described later.

One of the three different ways of connecting the guide ring gear and the control-side planetary gear is to connect the control-side planetary gear to a large gear and a planetary gear integrally having small gears on the left and right of the large gear. A ring gear fixed to the chassis is provided, and one small gear of the control planetary gear meshing with the sun gear and the ring gear fixed to the chassis are meshed with one small gear and a guide ring gear. The controller rotates the planetary gear on the control side and revolves to drive the guide ring gear in the opposite direction to the input.

The second of the three different ways of connecting the guide ring gear and the planetary gear on the control side is that a ring gear fixed to the chassis is also provided, and the small planetary gear integrated with the large and small gears meshing with the sun gear. The guide ring gear is fixed so that it meshes with the gear of the control side and rotates integrally with the support frame of the planetary gear on the control side. The sun gear rotates and revolves the planetary gear on the control side, and the guide ring gear together with the support frame. Is driven in the reverse direction of the input.

A third method of connecting the above-mentioned three different guide ring gears to the control planetary gear is to fix the support frame of the control planetary gear integrated with the large and small gears to the chassis, The guide ring gear meshes with the sun gear, and the planetary gear on the control side is rotated by the sun gear to drive the guide ring gear in the opposite direction to the input.

The driving in the reverse direction of the input of the guide ring gear by the connection method of the three different guide ring gears and the planetary gear on the control side is one rotation of the planetary gear on the input side, and the rotation of the planetary gear on the input side is large. This is the value (distance) obtained by multiplying the smaller gear of the input-side planetary gear by the pi, and the supporting frame of the control-side planetary gear or the ring gear that meshes with the control-side planetary gear is the chassis. By fixing, the driving force in the opposite direction of the input of the guide ring gear works smoothly.
