Description

High Efficiency Continuous Transmission

The present invention relates to a high efficiency continuous transmission device, and more particularly, as a type of continuously variable transmission, a high efficiency continuous speed shifting operation is easily performed using a planetary gear, a hydraulic pump, a hydraulic motor, and a flow control valve. Relates to a device.

As is well known, the continuously variable transmission is a device that can continuously change the rotational speed of the engine without a step, and the engine is operated in the region with the highest efficiency, improving fuel economy, and no impact due to the change in the number of stages. There is an advantage.

CVT is mainly composed of driving pulley, driven pulley, high tension belt connected between drive and driven pulley, and continuous stepless transmission is achieved by these configurations. Much research has been done on the method of adjustment and actual product has been made.

As an example, referring to the accompanying FIG. 1, a traction type continuous increase / deceleration ratio adjusting apparatus is as follows.

Conventional traction-type continuous increase / deceleration ratio adjusting device is a kind of continuously variable transmission, and the rotation speed is increased or decreased by the difference between the radius Rin of the input shaft 11 and the radius Rout of the output shaft 12, and the cone By changing the angle of (13, cone) continuously and the radius Rin of the input shaft 11 and the radius Rout of the output shaft 12 continuously, the increase / deceleration ratio can be continuously changed. It is structured.

However, the conventional continuous increase / deceleration ratio adjusting device as described above cannot transmit high rotational power because it transmits power by friction at the surface where the cone 13 is contacted, it is difficult to process the contact surface, and it is difficult to obtain a high reduction ratio. However, there is a disadvantage in that the largest transmission ratio can be made only by the difference in the cone angle.

As another example, referring to the attached FIG. 2, the belt-type continuous increase / deceleration ratio adjusting apparatus will be briefly described as follows.

Conventional belt type continuous gear ratio adjustment device is also a kind of continuously variable speed gear, and the variable pulleys (23, 24) having variable widths are mounted on two shafts (21, 22), respectively, so that the width of the variable pulleys (23, 24) can be adjusted. It is designed to continuously change the radius of rotation transmitted by changing, thereby obtaining a continuous increase / deceleration ratio.

However, the conventional belt-type continuous increase / deceleration ratio adjusting device as described above requires a separate device for shifting the width of the

variable pulleys

23 and 24, and its rotation radius cannot be reduced indefinitely, so that the reduction ratio is not large and the belt of high tension It is difficult to transfer the high rotational power because the 25 continuously produces variations in the rotation radius along with a slip phenomenon that slides along the surfaces of the

variable pulleys

23 and 24.

In addition, an output gear 124 is engaged with the transmission gear 122, and an output shaft 130 is connected to the output gear 124.

Meanwhile, a pump drive gear 132 is connected to the first ring gear 104, which is a fixed side gear element of the first planetary gear device 110, and a pump drive idle gear 134 is connected to the pump drive gear 132. Is engaged, and the pump gear 136 is meshed with the pump drive idle gear 134.

At this time, the shaft of the pump gear 136 is connected to the regenerative hydraulic pump 138 that operates while pumping hydraulic oil from the oil pan 156 by the driving of the pump gear 136.

In particular, a regenerative output gear 146 is connected to the second ring gear 114, which is a fixed side gear element of the regenerative second planetary gear device 120, and the regenerative output gear 146 is connected to the regenerative idle gear. The gear 144 meshes with the regenerative input gear 142 in the regenerative idle gear 144.

At this time, the regenerative input gear 142 is connected to the output shaft of the regenerative hydraulic motor 140, and receives the rotational power.

On the other hand, the hydraulic pump 138 and the regenerative hydraulic motor 140 is connected by the hydraulic supply line 152 to supply the hydraulic pressure from the hydraulic pump 138 to the regenerative hydraulic motor 140, at the same time for regenerative The hydraulic discharge line 154 is connected between the hydraulic motor 140 and the oil pan 156 to return the flow rate used in the hydraulic motor 140.

In addition, in order to control the flow rate of the regenerative hydraulic motor 140 to obtain a continuous stepless speed ratio, the hydraulic supply line 152 between the hydraulic pump 138 and the regenerative hydraulic motor 140 has a flow control valve ( 160 is installed, the relief valve 162 is installed in the hydraulic discharge line 154 between the regenerative hydraulic motor 140 and the hydraulic pump 138, the relief valve is a hydraulic motor 140 and hydraulic In order to correct the difference between the flow rate and the pressure between the pumps (138) serves to supply a partial return flow rate to the hydraulic supply line (152).

Here, the operation flow for the continuous transmission apparatus according to the first embodiment is as follows.

When the rotational power transmitted from the input shaft 100 is input to the first sun gear 102 of the first planetary gear device 110 for input and the second sun gear 112 of the second planetary gear device 120, the first sun gear The first and second

planetary gears

106 and 116, which are rotated at the same speed as the 102 and the second sun gear 112, are engaged with the outer circumferences of the first and second sun gears 102 and 112, respectively. Rotation and idle rotation are performed along the second ring gears 104 and 114.

Accordingly, the first and

second carriers

108 and 118 integrated with the first and second

planetary gears

106 and 116 rotate, and the transmission gear 122 connected to the outer diameters of the first and

second carriers

108 and 118, respectively. And through the output gear 124 meshed with the transmission gear 122, the output to the output shaft 130 is made.

At this time, the first ring gear 104, which is the fixed side gear element of the first planetary gear device 110, and the second ring gear 114, which is the fixed side gear element of the second planetary gear device 120, are separate. Since it is not constrained by the brake of the first and second

planetary gears

106 and 116, the rotational force is transmitted to rotate.

At the same time, the rotational force of the first ring gear 104 is transmitted to the pump drive gear 132 and at the same time the rotational direction of the pump drive idle gear 134 is changed to transmit the rotational force to the pump gear 136, thereby pumping The hydraulic pump 138 coaxially connected with the gear 136 is driven.

Accordingly, the hydraulic oil pumped from the oil pan 156 by the driving of the hydraulic pump 138 is supplied to the regenerative hydraulic motor 140 along the hydraulic supply line 152 to drive the regenerative hydraulic motor 140. This is made, the hydraulic oil exiting the hydraulic motor 140 is returned to the oil pan 156 along the hydraulic discharge line 154.

At this time, the flow rate control of the hydraulic oil supplied to the regenerative hydraulic motor 140 by the flow control valve 160 installed in the hydraulic supply line 152 is made, along the hydraulic discharge line 154 to the oil pan 156. As a part of the returned hydraulic oil is supplied to the hydraulic supply line 152 through the relief valve 162, compensation for the flow rate and pressure difference between the hydraulic motor 140 and the hydraulic pump 138 is performed.

As such, the hydraulic pump 138 is driven by the rotation of the first ring gear 104 to discharge hydraulic oil in proportion to the input rotational speed of the hydraulic pump 138. However, the flow control valve 160 By controlling the discharge flow rate of the hydraulic oil in the), the hydraulic pump 138 eventually serves to control the rotational speed of the first ring gear 104, which is a fixed side gear element.

That is, by the discharge flow rate of the hydraulic pump 138 and the flow rate control by the flow rate control valve 160, the rotation speed of the first ring gear 104 is varied and the rotation speed of the first planetary gear 106 is also varied. As a result, the rotation of the first carrier 108 connected to the output shaft 130 is adjusted, and the shift of the output shaft 130 is freely made.

More specifically, the first planetary gear 106 is controlled by the discharge flow rate of the hydraulic pump 138 and the flow rate control by the flow control valve 160 to increase the rotation speed of the first ring gear 104. ) And the first carrier gear 108 and the first carrier 108 under the control that the output shaft 130 rotates at high speed and the rotation speed of the first ring gear 104 is decreased. The number of revolutions of 108 decreases so that various speed changes are continuously performed, such as the output shaft 130 rotates at a low speed.

In this way, the rotation speed of the first ring gear 104 is controlled by the hydraulic pump 138 and the flow control valve 160, and the rotational force is added or outputted through the first carrier 108, thereby enabling continuous shifting. In accordance with the increase in the hydraulic pressure, it is possible to easily change the speed of the high load.

Accordingly, the rotational force of the regenerative output gear 146 acts on the second ring gear 114 of the regenerative second planetary gear device 120 connected coaxially, thereby accelerating rotation of the second ring gear 114. You lose.

More specifically, the output is made through the first carrier 108 and the second carrier 118 as described above, and the hydraulic motor 140 of the output stage receives the hydraulic energy discharged from the hydraulic pump 138 to receive the rotational force. By regenerating and transmitting to the second ring gear 114, the rotational force of the second ring gear 114 is transmitted to the second planetary gear 116 and the second carrier 118, and is connected to the second carrier 118. High efficiency and high load power transmission to the output shaft 130 is made.

The second planetary gear device 120 for regeneration including a planetary gear device 110 and a second carrier 118 having a second sun gear 112, a second ring gear 114, and a second planetary gear 116. ) Is combined, and the input shaft 100 extending from the crankshaft of the engine is simultaneously connected to the first and second sun gears 102 and 112.

planetary gears

106 and 116, which are rotated at the same speed as the 102 and the second sun gear 112, are engaged with the outer circumferences of the first and second sun gears 102 and 112, respectively. The first and second ring gears 104 and 114 are rotated while rotating and rotating along the second ring gears 104 and 114.

Accordingly, the rotational forces of the first and second ring gears 104 and 114 are output to the output shaft 130 through the transmission gear 122 and the output gear 124.

At this time, the first carrier 108 which is the fixed side gear element of the first planetary gear device 110 and the second carrier 118 that is the fixed side gear element of the second planetary gear device 120 are separate brakes. Since it is not constrained by the rotational force, the rotational force of the first and second

planetary gears

106 and 116 is transmitted.

At the same time, the rotational force of the first carrier 108 is transmitted to the pump drive gear 132 and at the same time the rotational direction is changed in the pump drive idle gear 134 to transmit the rotational force to the pump gear 136, thereby, the pump gear A hydraulic pump 138 coaxially connected with 136 is driven.

As such, the hydraulic pump 138 is driven by the rotation of the first carrier 108 to discharge hydraulic oil proportionally according to the input rotational speed of the hydraulic pump 138, but the flow control valve 160 By controlling the discharge flow rate of the hydraulic oil in, the hydraulic pump 138 eventually serves to control the rotational speed of the first carrier 108, which is a fixed side gear element.

That is, by the discharge flow rate of the hydraulic pump 138 and the flow rate control by the flow control valve 160, the rotation speed of the first carrier 108 is varied and the rotation speed of the first planetary gear 106 is also varied. As the rotation speed of the first ring gear 104 connected to the output shaft 130 is adjusted, the shift to the output shaft 130 is freely made.

More specifically, the first planetary gear 106 is controlled by the discharge flow rate of the hydraulic pump 138 and the flow rate control by the flow control valve 160 to increase the rotation speed of the first carrier 108. And the first planetary gear 106 and the first ring gear when the output shaft 130 rotates at high speed and the rotation speed of the first carrier 108 is reduced. The rotational speed of the 104 is reduced so that various speed changes are continuously performed, such as the output shaft 130 rotates at a low speed.

In this way, the rotational speed of the first carrier 108 is controlled by the hydraulic pump 138 and the flow control valve 160, and the rotational force is added or outputted through the first ring gear 104, thereby enabling continuous shifting.
