Description

Technical Field

[0001] This application belongs to the field of agricultural machinery, specifically relating to a power output system for agricultural machinery and the agricultural machinery itself. Background Technology

[0002] Traditional agricultural machinery uses engines or hydraulic motors to drive its components, which results in high energy consumption and difficulty in control. Driven by environmental protection requirements, electric-driven agricultural machinery has emerged. Electric-driven agricultural machinery uses electric motors to replace the motors or pulleys of traditional agricultural machinery, enabling direct motor drive of the machinery, which is highly efficient and has good controllability.

[0003] Currently, agricultural direct-drive machinery on the market mainly connects the motor to the input shaft of an existing AMT (Automated Manual Transmission) gearbox. The AMT gearbox has two gears and also requires a motor actuator and a TCU (Traffic Control Unit) controller. This makes existing agricultural direct-drive machinery complex and costly. Furthermore, the input and output shafts of the AMT gearbox are constrained by its structure and must be arranged in parallel, making it unsuitable for applications requiring axial installation. Utility Model Content

[0004] The purpose of this application is to provide a power output system and a working machine for use in operating machinery, in order to solve the problems of complex structure, high cost, and unsuitability for axial installation in existing direct-drive electric motor operating machinery.

[0005] To achieve the above objectives, the first aspect of this application provides a power output system for a work machinery, comprising: Drive motor; The control module is electrically connected to the drive motor; and A planetary gearbox is provided with a power input shaft that is driven to the drive motor and a power output shaft for connecting a load. The end of the power input shaft away from the drive motor is driven to the sun gear or a rotating internal gear ring in the planetary gearbox. The power output shaft extends along the axis of the power input shaft and is driven to the sun gear and the internal gear ring respectively through a one-way clutch. The locking direction of the one-way clutch disposed between the power output shaft, the sun gear, and the internal gear ring is consistent.

[0006] As a further improvement to the above technical solution: In some implementations, the one-way clutch is a one-way overrunning clutch.

[0007] In some embodiments, between the sun gear and the power output shaft, the inner ring of the one-way overrunning clutch is engaged with the power output shaft to prevent rotation, and the outer ring of the one-way clutch is engaged with the sun gear to prevent rotation. Between the internal gear ring and the power output shaft, the inner ring of the one-way overrunning clutch is engaged with the power output shaft to prevent rotation, and the outer ring of the one-way clutch is engaged with the internal gear ring to prevent rotation.

[0008] In some implementations, the one-way clutch between the sun gear and the power output is defined as a first one-way clutch, and the one-way clutch between the internal gear ring and the power output is defined as a second one-way clutch. Specifically, when the power input shaft is connected to the sun gear drive, the transmission ratio when the power input shaft transmits power to the power output shaft through the first one-way clutch is 1.

[0009] In some implementations, the one-way clutch between the sun gear and the power output is defined as a first one-way clutch, and the one-way clutch between the internal gear ring and the power output is defined as a second one-way clutch. Specifically, when the power input shaft is connected to the internal gear ring, the transmission ratio of the power input shaft transmitting power to the internal gear ring through the second one-way clutch is 1.

[0010] In some embodiments, the planetary gearbox further includes a planet carrier and at least one planet gear disposed on the planet carrier; The planetary carrier is fixedly mounted on the housing of the planetary gearbox, and the planetary gears are rotatably mounted on the planetary carrier and mesh with the sun gear and the internal gear ring respectively.

[0011] In some implementations, the control module is a motor controller, which is used to communicate with the vehicle controller in the working machinery.

[0012] The second aspect of this application also provides a work machine, including a power output system for the work machine according to the first aspect above.

[0013] As a further improvement to the above technical solution: In some embodiments, the working machinery further includes a vehicle controller, which is communicatively connected to the control module.

[0014] In some embodiments, the machine further includes an energy storage device that supplies power to the control module and the drive motor.

[0015] Compared with the prior art, this application provides a power output system for operating machinery and operating machinery, which has at least the following beneficial effects: The power output system for work machinery provided in this application is connected to a drive motor via the power input shaft of a planetary gearbox. The power input shaft is connected to either the sun gear or a rotating internal gear ring within the planetary gearbox. The power output shaft extends along the axis of the power input shaft and is connected to both the sun gear and the internal gear ring via a one-way clutch. The axial directions of the power output shaft and the power input shaft are aligned, and the locking directions of the one-way clutches between the power output shaft and the sun gear and internal gear ring are the same. Thus, in the power output system for work machinery provided in this application, because the locking directions of the two one-way clutches between the power output shaft and the sun gear and internal gear ring are the same, power can be transmitted to the power output shaft by controlling forward / reverse rotation using the corresponding one-way clutches. Furthermore, since the sun gear and internal gear ring in the planetary gearbox rotate in the same direction but have different output gear ratios, it can ensure that the power output shaft rotates in the same direction and can output different speeds. This eliminates the need for a TCU controller, thereby simplifying the structure of the entire power output system for work machinery and reducing costs. Furthermore, since the power output shaft extends along the axis of the power input shaft, the power output shaft and the power input shaft are coaxially arranged, which can be used in applications requiring axial installation.

[0019] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0020] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0021] Example 1 Please see Figure 1 This embodiment provides a power output system for agricultural machinery, which can be applied to agricultural machinery.

[0022] The power output system for the operating machinery includes a drive motor 200, a control module 300, and a planetary gearbox 100; the control module 300 is electrically connected to the drive motor 200, and the control module 300 can control the speed, torque, and forward and reverse switching of the drive motor 200.

[0023] The planetary gearbox 100 has a housing 110, within which a planetary gear system is housed. The planetary gearbox 100 has a power input shaft 120 that is connected to the drive motor 200, and a power output shaft 130 for connecting a load, which may be the traveling mechanism of a work machine or a work attachment, etc.

[0024] In this embodiment, the end of the power input shaft 120 away from the drive motor 200 is connected to the sun gear 140 within the planetary gearbox 100, thus the sun gear 140 serves as the power input gear. The power output shaft 130 extends along the axis of the power input shaft 120, and the power output shaft 130 is connected to the sun gear 140 and the internal gear ring 170 via a one-way clutch 180. For clarity, this embodiment defines the one-way clutch 180 between the sun gear 140 and the power output shaft 130 as the first one-way clutch 180a, and the one-way clutch 180 between the internal gear ring 170 and the power output shaft 130 as the second one-way clutch 180b. The first one-way clutch 180a connects the sun gear 140 and the power output shaft 130, while the second one-way clutch 180b connects the internal gear ring 170, which rotates within the planetary gearbox 100, and the power output shaft 130.

[0025] Since the power output shaft 130 extends along the axis of the power input shaft 120, the axes of the power output shaft 130 and the power input shaft 120 are on the same straight line, achieving coaxial arrangement. The locking directions of the first one-way clutch 180a and the second one-way clutch 180b are the same.

[0026] Furthermore, the planetary gearbox 100 also includes a planet carrier 150 and at least one planet gear 160 disposed on the planet carrier 150. The planet carrier 150 is fixedly mounted on the housing 110 of the planetary gearbox 100, and the planet gear 160 is rotatably disposed on the planet carrier 150 and meshes with the sun gear 140 and the internal ring gear 170 respectively. Thus, in this embodiment, due to the action of the planet gear 160, the internal ring gear 170 and the sun gear 140 in the planetary gearbox 100 can always maintain the same direction of rotation.

[0027] It is understood that the number of planetary gears 160 can be set to one, two, three, or other quantities depending on the size of the internal gear ring 170 in the planetary gearbox 100 and the operating requirements of the planetary gearbox 100. Therefore, in this embodiment, the number of planetary gears 160 is not specifically limited.

[0028] To more clearly describe the technical solution of this application, it is defined that when the internal gear ring 170 and the sun gear 140 rotate forward, the corresponding first one-way clutch 180a and second one-way clutch are in an unlocked state and do not transmit power to the power output shaft 130. When the internal gear ring 170 and the sun gear 140 rotate forward, the corresponding first one-way clutch 180a and second one-way clutch are in a locked state and can transmit power to the power output shaft 130.

[0029] Please refer to the following: Figure 2 and Figure 3Thus, the power output system for the operating machinery provided in this embodiment has two power transmission routes, specifically: like Figure 2 As shown, transmission route 1: power input shaft 120 drives sun gear 140 to reverse (arrow pointing down) - power output shaft 130 reverses under the action of the first one-way clutch 180a (arrow pointing down, at this time the internal gear ring 170 is rotating forward, and the second one-way clutch 180b is in the unlocked state) - power output shaft 130 drives the load to reverse (arrow pointing down).

[0030] like Figure 3 As shown, transmission route 2: the power input shaft 120 drives the sun gear 140 to rotate forward (arrow pointing upward, at which time the first one-way clutch 180a is in the unlocked state) - the planetary gear 160 rotates in reverse (arrow pointing downward) - the internal gear ring 170 rotates in reverse - the power output shaft 130 rotates in reverse under the action of the second one-way clutch 180b (arrow pointing downward) - the power output shaft 130 drives the load to rotate in reverse (arrow pointing downward).

[0031] In this embodiment, by ensuring that the locking directions of the first one-way clutch 180a and the second one-way clutch are consistent, it can be ensured that regardless of whether the drive motor 200 drives the power input shaft 120 to rotate forward or backward, after transmitting power to the power output shaft 130 through the corresponding first one-way clutch 180a or second one-way clutch 180b, the rotation direction output by the power output shaft 130 remains consistent. Thus, the power output system for the working machinery provided in this embodiment can directly control the forward / reverse rotation and the engagement / disengagement of the first one-way clutch 180a and the second one-way clutch to achieve the same rotation of the power output shaft 130 and output different speeds (the speeds output by transmission route 1 and transmission route 2 are different, but the direction of rotation of the power output shaft 130 is consistent). Therefore, there is no need to configure a TCU controller (gearbox controller), thereby simplifying the structure of the entire power output system for the working machinery and reducing costs.

[0032] Furthermore, since the power output shaft 130 extends along the axis of the power input shaft 120, the power output shaft 130 and the power input shaft 120 can be installed with coaxiality, thus making it suitable for use in applications requiring axial installation.

[0033] Furthermore, the power input shaft 120 is directly driven connected to the sun gear 140, for example, by welding, flange connection, key, or spline connection. Thus, in the case of transmission route 1 described above, the transmission ratio between the power input shaft 120 and the power output shaft 130 is 1.

[0034] In some embodiments, the power input shaft 120 and the sun gear 140 can also be meshed by a gear set, which can also achieve a transmission ratio of 1 between the power input shaft 120 and the power output shaft 130 in the case of the above transmission route 1.

[0035] Optionally, the first one-way clutch 180a is a one-way overrunning clutch; wherein, the inner ring of the first one-way clutch 180a is engaged with the power output shaft 130 to prevent rotation, and the outer ring of the first one-way clutch 180a is engaged with the sun gear 140 to prevent rotation.

[0036] Optionally, the second one-way clutch 180b is a one-way overrunning clutch; wherein, the inner ring of the second one-way clutch 180b is engaged with the power output shaft 130 to prevent rotation, and the outer ring of the second one-way clutch 180b is engaged with the internal gear ring 170 to prevent rotation.

[0037] Optionally, the control module 300 is a motor controller, which is used to communicate with the vehicle controller 400 in the working machinery. The motor controller can accept torque commands sent by the vehicle controller 400 and precisely control the drive motor 200 to output torque of the corresponding magnitude and direction; the motor controller can also control the speed, forward / reverse rotation, etc. of the drive motor 200.

[0038] Furthermore, this embodiment also provides a type of machinery, particularly an agricultural machinery. Agricultural machinery can perform tasks such as cutting, feeding, threshing, and removing impurities from crops, such as an agricultural harvester.

[0039] The operating machinery includes the power take-off system for operating machinery provided above. The power take-off system for operating machinery has been described in detail above and will not be repeated here.

[0040] The operating machinery also includes a vehicle controller 400 and an energy storage device 500, with the vehicle controller 400 communicating with the control module 300. The energy storage device 500 supplies power to the control module 300, the vehicle controller 400, and the drive motor 200. The energy storage device 500 can be a battery pack.

[0041] Example 2 Please see Figure 4 This embodiment provides a power output system for agricultural machinery, which can be applied to agricultural machinery.

[0042] The power output system for the operating machinery includes a drive motor 200, a control module 300, and a planetary gearbox 100; the control module 300 is electrically connected to the drive motor 200, and the control module 300 can control the speed, torque, and forward and reverse switching of the drive motor 200.

[0043] The planetary gearbox 100 has a housing 110, within which a planetary gear system is housed. The planetary gearbox 100 has a power input shaft 120 that is connected to the drive motor 200, and a power output shaft 130 for connecting a load, which may be the traveling mechanism of a work machine or a work attachment, etc.

[0044] In this embodiment, the end of the power input shaft 120 away from the drive motor 200 is connected to a rotating internal gear ring 170 within the planetary gearbox 100, thus the internal gear ring 170 serves as the power input gear. The power output shaft 130 extends along the axis of the power input shaft 120, and is connected to the sun gear 140 and the internal gear ring 170 via a one-way clutch 180. For clarity, in this embodiment, the one-way clutch 180 between the sun gear 140 and the power output shaft 130 is defined as the first one-way clutch 180a, and the one-way clutch 180 between the internal gear ring 170 and the power output shaft 130 is defined as the second one-way clutch 180b. The first one-way clutch 180a connects the sun gear 140 and the power output shaft 130, and the second one-way clutch 180b connects the rotating internal gear ring 170 within the planetary gearbox 100 and the power output shaft 130.

[0045] Since the power output shaft 130 extends along the axis of the power input shaft 120, the axes of the power output shaft 130 and the power input shaft 120 are on the same straight line, achieving coaxial arrangement. The locking direction of the first one-way clutch 180a and the second one-way clutch is the same.

[0046] Furthermore, the planetary gearbox 100 also includes a planet carrier 150 and at least one planet gear 160 disposed on the planet carrier 150. The planet carrier 150 is fixedly mounted on the housing 110 of the planetary gearbox 100, and the planet gear 160 is rotatably disposed on the planet carrier 150 and meshes with the sun gear 140 and the internal ring gear 170 respectively. Thus, in this embodiment, due to the action of the planet gear 160, the internal ring gear 170 and the sun gear 140 in the planetary gearbox 100 can always maintain the same direction of rotation.

[0047] It is understood that the number of planetary gears 160 can be set to one, two, three, or other quantities depending on the size of the internal gear ring 170 in the planetary gearbox 100 and the operating requirements of the planetary gearbox 100. Therefore, in this embodiment, the number of planetary gears 160 is not specifically limited.

[0048] To more clearly describe the technical solution of this application, it is defined that when the internal gear ring 170 and the sun gear 140 rotate forward, the corresponding first one-way clutch 180a and second one-way clutch are in an unlocked state and do not transmit power to the power output shaft 130. When the internal gear ring 170 and the sun gear 140 rotate forward, the corresponding first one-way clutch 180a and second one-way clutch are in a locked state and can transmit power to the power output shaft 130.

[0049] Please refer to the following: Figure 5 and Figure 6Thus, the power output system for the operating machinery provided in this embodiment has two power transmission routes, specifically: like Figure 5 As shown, transmission route 1: the power input shaft 120 drives the internal gear ring 170 to reverse (arrow pointing down) - the power output shaft 130 reverses under the action of the second one-way clutch 180b (arrow pointing down, at this time the sun gear 140 is rotating forward and the first one-way clutch 180a is in the unlocked state) - the power output shaft 130 drives the load to reverse (arrow pointing down).

[0050] like Figure 6 As shown, transmission route 2: the power input shaft 120 drives the internal gear ring 170 to rotate forward (arrow pointing upward, at this time the second one-way clutch 180b is in the unlocked state) - the planetary gear 160 rotates forward (arrow pointing upward) - the sun gear 140 rotates in reverse - the power output shaft 130 rotates in reverse under the action of the first one-way clutch 180a (arrow pointing downward) - the power output shaft 130 drives the load to rotate in reverse (arrow pointing downward).

[0051] In this embodiment, by ensuring that the locking directions of the first one-way clutch 180a and the second one-way clutch are consistent, it can be ensured that regardless of whether the drive motor 200 drives the power input shaft 120 to rotate forward or backward, after transmitting power to the power output shaft 130 through the corresponding first one-way clutch 180a or second one-way clutch 180b, the rotation direction output by the power output shaft 130 remains consistent. Thus, the power output system for the working machinery provided in this embodiment can directly control the forward / reverse rotation and the engagement / disengagement of the first one-way clutch 180a and the second one-way clutch to achieve the same rotation of the power output shaft 130 and output different speeds (the speeds output by transmission route 1 and transmission route 2 are different, but the direction of rotation of the power output shaft 130 is consistent). Therefore, there is no need to configure a TCU controller, thereby simplifying the structure of the entire power output system for the working machinery and reducing costs.

[0052] Furthermore, since the power output shaft 130 extends along the axis of the power input shaft 120, the power output shaft 130 and the power input shaft 120 can be installed with coaxiality, thus making it suitable for use in applications requiring axial installation.

[0053] Furthermore, the power input shaft 120 is directly driven connected to the side of the internal gear ring 170 facing away from the sun gear 140, for example, by welding, flange connection, key, or spline connection. Thus, in the case of transmission route 1 described above, the transmission ratio between the power input shaft 120 and the internal gear ring 170 is 1. The transmission ratio between the power input shaft 120 and the power output shaft 130 depends on the tooth count relationship of the internal gear ring 170, planet gears 160, and sun gear 140.

[0054] In some embodiments, the power input shaft 120 and the internal gear ring 170 can also mesh through a gear set, which can also achieve a transmission ratio of 1 between the power input shaft 120 and the internal gear ring 170 in the case of the above-described transmission route 1.

[0055] Optionally, the first one-way clutch 180a is a one-way overrunning clutch; wherein, the inner ring of the first one-way clutch 180a is engaged with the power output shaft 130 to prevent rotation, and the outer ring of the first one-way clutch 180a is engaged with the sun gear 140 to prevent rotation.

[0056] Optionally, the second one-way clutch 180b is a one-way overrunning clutch; wherein, the inner ring of the second one-way clutch 180b is engaged with the power output shaft 130 to prevent rotation, and the outer ring of the second one-way clutch 180b is engaged with the internal gear ring 170 to prevent rotation.

[0057] Optionally, the control module 300 is a motor controller, which is used to communicate with the vehicle controller 400 in the working machinery. The motor controller can accept torque commands sent by the vehicle controller 400 and precisely control the drive motor 200 to output torque of the corresponding magnitude and direction; the motor controller can also control the speed, forward / reverse rotation, etc. of the drive motor 200.

[0058] Furthermore, this embodiment also provides a type of machinery, particularly an agricultural machinery. Agricultural machinery can perform tasks such as cutting, feeding, threshing, and removing impurities from crops, such as an agricultural harvester.

[0059] The operating machinery includes the power take-off system for operating machinery provided above. The power take-off system for operating machinery has been described in detail above and will not be repeated here.

[0060] The operating machinery also includes a vehicle controller 400 and an energy storage device 500, with the vehicle controller 400 communicating with the control module 300. The energy storage device 500 supplies power to the control module 300, the vehicle controller 400, and the drive motor 200. The energy storage device 500 can be a battery pack.
