Description

Continuously variable transmission {CONTINUOUSLY VARIABLE TRANSMISSION}

The present invention comprises a variable rotation slider 201, a main slider 107, 108 for linear reciprocating motion, and a transmission gear 109, 110 combined with a one-way bearing. The present invention relates to a continuously variable automatic transmission in which power loss rarely occurs during power transmission and is capable of continuous and various shifts.

Current power machines use transmissions to make efficient use of power. Such devices include manual transmissions and automatic transmissions. The manual transmission is very economical due to its simple parts and excellent fuel economy, but it is inconvenient to operate and can only be operated by skilled personnel. In addition, the automatic transmission transmits power hydraulically through the torque converter and is stepped through the planetary gear. Such automatic transmission is convenient to use, but the device is very complicated, expensive to manufacture, and the power is transmitted by hydraulic pressure, so slippage occurs during acceleration and deceleration, and its own weight is heavy, resulting in low efficiency and high maintenance costs.

The present invention is a device designed to solve various problems of existing transmissions. Manual transmissions are quite inconvenient to operate and can only be operated by skilled personnel. On the other hand, automatic transmissions are convenient to use, but the structure is complicated, the manufacturing cost is high, and the power is transmitted by hydraulic pressure. The transmission itself is heavy and the transmission ratio is not variable so it does not operate efficiently. Thus, the purpose is to solve the problems of the automatic transmission and the manual transmission at the same time.

In order to solve the above problems, the present invention attaches gears to the two one-way bearings, respectively, and then fixes the power transmission direction to the rotation shaft 110 to be matched with each other. When the main gears are linearly reciprocated by assembling the rack gears and the transmission gears 109 and 110, the transmission gears reciprocate and the rotation shaft 110 is configured to continuously rotate only in one direction. In order to linearly reciprocate the main slider device, one side of the variable rotary slider 201 is connected to the rail groove 200 and the other side is connected to the rail groove 202 of the auxiliary rotary surface 102. The main slider is configured to make a straight reciprocating motion when the variable rotation slider moves in conjunction with the main slider device (106). In order to properly adjust the rotation radius of the variable rotary slider 201, the wire 104 is connected to the upper part of the variable rotary slider face connected to the auxiliary rotary plane rail groove, and the wire 104 is brought out to the outside through the center of the auxiliary rotary shaft 103, and then the bearing is connected to the wire. Connected together with the wire 105 connected to the 203 is configured so that the wire is not twisted even if the rotating plate and the auxiliary rotation surface rotates together. When the radius of rotation of the variable rotary slider is changed by pulling or releasing the end of the wire 105, the linear reciprocating length of the main slider is also changed, and the size of the reciprocating rotation of the transmission gear is also changed to transmit torque to the rotating shaft 110. And the rotational speed is also changed to enable continuous continuously variable speed.

In the present invention, the power shaft 100 and the rotary shaft 111 are directly connected as described above, so power transmission is accurate, so that almost no loss occurs, and continuous automatic shifting without permission is possible. In addition, the shock hardly occurs during shifting, and the device is very simple and light, so the production cost is low and various transmission ratios can be obtained.

The main components of the present invention are composed of a transmission gear device (109, 110), a main slider device (107, 108), a variable rotating slider device (201), an auxiliary rotating surface (102). Detailed description and operation principle of each configuration will be described in detail with the accompanying drawings.

1. Looking at the configuration of the transmission gears (109, 110), the gears are attached to two one-way bearings, respectively, to match the direction of transmitting power to the rotating shaft 111, and then the two transmission gears are fixed to the rotating shaft 111 groove to transmit the transmission. Language (see Figure 2).

2. Looking at the configuration of the main slider device, the rack gears on the main slider frame surface (107) and below (108) are made cross-assembled, and the gears (109, 110) are engaged with the rack gears, and then the variable with the loader (106). To the rotary slider 201. When the rotary plate 101 is rotated by connecting as described above, the variable rotary slider rotates according to the rotation radius, and the main slider can perform a linear reciprocating motion (see FIG. 3).

The operation principle of the transmission gear and the main slider device will be described in detail. When the variable rotary slider 201 is rotated, the main slider linearly reciprocates and the transmission gears 109 and 110 reciprocate through the rack gears above and below the frame. work out. One-way bearing is characterized in that the power is transmitted only in one direction, so if the main slide moves linearly from right to left, one transmission gear 110 rotates to transmit power to the rotating shaft 111 and the other transmission gear 109. ) Slides and rotates, preventing power from being transmitted to the rotating shaft. On the contrary, when the linear movement from the left to the right, the transmission gear 110 slips and does not transmit power, and the transmission gear 109 transmits power. In this way, the main slider continuously performs a linear reciprocating motion, and the transmission gear causes the rotating shaft 111 to continuously rotate in one direction while performing a reciprocating rotational motion (see FIGS. 2 and 3).

The configuration as described above can convert the linear reciprocating motion into the rotary motion without the crank, and the irregular rotational motion that occurs when the linear reciprocating motion is converted into the rotary motion is also caused by the sliding characteristic of the one-way bearing and the rotational inertia force of the rotary shaft 111. Regular rotational movements are possible, so no device like a fryer is needed.

3. Looking at the configuration of the variable rotary slider 201 connects one side of the variable rotary slider to move along the rail groove 200, the rotary plate 101 integrally with the power shaft 100, and the opposite side is the secondary rotary surface (102) rail When the rotating plate 101 is connected to the groove 202, the variable rotating slider and the maintenance rotating surface 102 are configured to rotate together. And when the loader 106 is connected to the center of the variable rotary slider and the other side is connected to the main sliders 107 and 108, when the rotating plate 101 rotates, the main slider connected to the loader is linearly reciprocated. As the main slider is also linearly reciprocated by the size of the rotation radius diameter (D) of the variable rotation slider, if the size of the rotation radius is properly adjusted, the torque and rotation speed transmitted to the rotation shaft 111 can be continuously changed. )

4. When explaining the configuration and operation principle of the auxiliary rotating surface for controlling the rotation radius of the variable rotary slider one side and the other side of the rotary plate 101 rail groove 200 is variable connected to the secondary rotating surface (102) rail groove 202 In order to properly control the rotation radius of the rotating slider 201, the wire 104 is connected to the upper part of the rotating slider surface connected to the auxiliary rotating surface rail groove 200, and the wire 104 comes out through the center of the auxiliary rotating shaft 103 and the wire The wire 105 is connected with the bearing 203 so that the wire is not twisted by the bearing even when the rotating plate and the auxiliary rotating surface rotate. By properly controlling the tension by pulling or releasing the end of the wire 105, it is possible to control the radius of rotation of the variable rotating slider by centrifugal force (see FIGS. 5 and 6).

When explaining the overall operating principle of the present invention

When the rotating plate 100 is rotated by the power in the state in which the respective devices are assembled, the variable rotating slider 201 connected to the rotating plate and the auxiliary rotating surface also rotates, and the main slider connected by the loader 106 linearly reciprocates. Will be When the main slider is linearly reciprocated, the transmission gears 109 and 110 connected to the rack gears of the frame 107 and 108 are reciprocated. The rotary shaft 110 transmits power only in one direction by the one-way bearing. Rotates continuously.

It describes in detail how to control the rotation radius of the variable rotation slider 201 for continuous stepless speed change. When the variable rotation slider rotates, the centrifugal force is generated by its own weight and moves to the edge along the rail grooves 200 and 202. I will try to. At this time, if the tension of the wire 105 is properly adjusted, the radius of rotation can be controlled. According to the size of the rotation radius, the linear reciprocating length of the main slider is changed and the size of the reciprocating rotation of the transmission gear connected to the rack gear is also changed to continuously change the torque and the rotation speed transmitted to the rotating shaft 110. Therefore, if the rotation radius of the variable rotary slider is properly controlled, a continuous continuously variable transmission is possible in a gear type.

1. When the rotation radius is 0 → The loader does not move and the main slider does not move. Therefore, no power is transmitted to the rotating shaft 111. The transmission becomes a neutral state (N) and the rotation speed becomes zero.

2. When the radius of rotation is greater than 0 → The main slider moves reciprocally as much as the diameter (D) of the radius of rotation, the transmission gear reciprocates by the length of the linear reciprocation, and the rotation shaft 111 moves the length of the reciprocation. Rotate continuously. The smaller the rotation radius, the greater the torque and the smaller the rotation speed.

3. When the radius of rotation is maximum → When the rotation plate 101, the rail groove 200 is located at the edge of the linear reciprocating length of the main slider is the maximum rotation axis 111 rotates the fastest and the torque is minimum.

1. When the vehicle starts, the wire 105 is gradually released to gradually increase the radius of rotation of the variable rotating slider to continuously change the speed of the vehicle. When the vehicle is stopped, pull the wire 105 as far as possible to bring the variable rotating slider 201 to the center of the rotating plate 101 so that the radius of rotation becomes close to zero, and the loader 106 does not move. Without the movement, the transmission gears 109 and 110 also do not reciprocate rotation, so no power is transmitted to the rotating shaft 111, and the transmission is in a neutral state (N). Therefore, the engine does not turn off even if the vehicle is stopped without stepping on the clutch like a conventional manual transmission. In addition, even if the vehicle is temporarily stopped on the inclined surface and the vehicle is started again, the existing vehicle is pushed back, but in the present invention, the rotating shaft 111 connected to the main slider cannot rotate in the opposite direction because the variable rotating slider continuously rotates while the vehicle is stopped. There is a characteristic of going forward, so the car will not be pushed back.

2. If you take off your car's accelerator pedal under high speed or constant speed operation, the control device will pull the wire 105 momentarily to be in the neutral state (N) as above so that the engine brake will not operate. Control to save fuel. If the brake or accelerator pedal is pressed during inertia operation, the control unit extends the wire 105 again to an appropriate length according to the driving state and rotates the variable rotating slider so that the engine brake can be safely stopped or accelerated again. do. When the brake is applied at low speed or sudden stop, the wire 105 is immediately pulled to maintain the neutral state N without inertia operation as described above, so that the engine does not turn off even when the vehicle is stopped.

3. If the vehicle is in a driving condition other than the above, continuously adjust the rotation radius of the variable rotating slider according to the control method of the existing automatic transmission according to the speed of the vehicle and the inclination weight.
