Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, and in particular relates to a power reversing and power high and low gear integrated module and agricultural machinery. Background Technology

[0002] With the development of agricultural machinery, tractors and other agricultural machinery are being used more and more widely in field operations in China. However, as the number of tractor-operated projects and supporting agricultural implements increases, tractors need to be equipped with multiple gears. The more gears there are, the more complex the structure becomes, which places higher demands on the market positioning and shifting quality of tractors.

[0003] Currently, the shifting of gears in domestic tractor transmission systems mainly uses meshing sleeves or synchronizers, while reversing is achieved by setting a reverse gear in the rear housing of the transmission system. The operating mechanism uses sliding gears, meshing sleeves, or synchronizers. The transmission device is not only complex in structure, but also has low integration and poor space utilization. Utility Model Content

[0006] In this embodiment of the utility model, the shaft assembly further includes an idler shaft with a reversing idler gear. The axes of the input shaft, the intermediate shaft, the output shaft, and the idler shaft are not coplanar. The reverse clutch is used to transmit power to the intermediate shaft through the reversing idler gear.

[0007] In this embodiment of the utility model, the forward clutch is used to engage the forward gear, the intermediate shaft is provided with a first gear that is motive-connected to the forward gear, the reverse clutch is used to engage the reverse gear, the intermediate shaft is provided with a second gear that is motive-connected to the reversing idler wheel, and the reversing idler wheel is motive-connected to the reverse gear.

[0008] In this embodiment of the utility model, the power reversing and power high / low gear integration module includes a low gear that is drivenly connected to the first gear and a high gear that is drivenly connected to the second gear. The low gear clutch is used to engage the low gear, and the high gear clutch is used to engage the high gear. The transmission ratio between the first gear and the low gear is a first transmission ratio, and the transmission ratio between the second gear and the high gear is a second transmission ratio. The first transmission ratio is greater than the second transmission ratio.

[0009] In this embodiment of the invention, the input shaft and the output shaft are sequentially arranged on a first horizontal plane. The first horizontal plane and the axis of the idler shaft are not coplanar. The intermediate shaft is located vertically between the input shaft and the output shaft.

[0010] In this embodiment of the invention, the axis of the input shaft, the axis of the intermediate shaft, the axis of the output shaft, and the axis of the idler shaft are located in different planes along the vertical direction.

[0011] In this embodiment of the invention, two of the axes of the input shaft, the intermediate shaft, the output shaft, and the idler shaft are located in a first plane, and the other two axes are located in a second plane.

[0013] In this embodiment of the invention, the forward clutch and the reverse clutch are both electro-hydraulic control automatic clutches; and / or, the low-gear clutch and the high-gear clutch are both electro-hydraulic control automatic clutches.

[0014] This utility model also proposes an agricultural machine, which includes the power reversing and power high and low gear integrated module as described above.

[0015] Through the above technical solution, the power reversing and high / low power gear integration module provided in this utility model embodiment has the following beneficial effects: The power reversing and high / low gear integration module integrates the forward clutch, reverse clutch, low gear clutch, and high gear clutch via the input shaft, intermediate shaft, and output shaft.

The forward and reverse clutches are sequentially arranged along the input shaft axis and share a common first outer hub, improving the structural compactness of the reversing device. The low gear clutch and high gear clutch are sequentially arranged along the output shaft axis outside the output shaft and integrated, sharing a common second outer hub, further enhancing the structural compactness of the power reversing and high / low gear integration module. The input shaft can be connected to the first outer hub via a first connecting bracket located between the forward and reverse clutches. The output shaft can be connected to the second outer hub via a second connecting bracket located between the low gear clutch and high gear clutch. This connection method between the input shaft, output shaft, and clutch outer hub fully utilizes the axial space of the power reversing and high / low gear integration module. In this invention, the two clutches share a single outer hub, resulting in a more compact structure. Integrating the clutches on two shafts can meet the needs of various application scenarios. Furthermore, eliminating the need for a clutch on the intermediate shaft reduces the center distance between the input and output shafts, thereby improving the space utilization of the power reversing and high / low gear integration module in multiple ways.

[0018] Explanation of reference numerals in the attached figures Detailed Implementation

[0019] The specific embodiments of this utility model 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 the scope of this utility model.

[0020] The following description, with reference to the accompanying drawings, describes the power reversing and high / low power gear integration module according to this utility model.

[0021] like Figures 1 to 5 As shown in the embodiment of this utility model, the power reversing and high / low gear integrated module 100 includes: a reversing device, a shifting device, and a shaft assembly. The reversing device includes a forward clutch C1, a reverse clutch C2, and a first outer hub 8. The forward clutch C1 and the reverse clutch C2 are housed in the first outer hub 8. The shifting device includes a low-gear clutch C3, a high-gear clutch C4, and a second outer hub 9. The low-gear clutch C3 and the high-gear clutch C4 are both housed in the second outer hub 9. The shaft assembly includes an input shaft S1, an intermediate shaft S2, and an output shaft S3. The axes of the input shaft S1, the intermediate shaft S2, and the output shaft S3 are not coplanar. The forward clutch C1 and the reverse clutch C2 are sequentially arranged on the input shaft S1 along the axial direction of the input shaft S1. The low-gear clutch C3 and the high-gear clutch C4 are sequentially arranged on the output shaft S3 along the axial direction of the output shaft S3. The input shaft S1 is used to transmit power to the output shaft S3 through the intermediate shaft S2.

[0022] It should be noted that the power reversing and high / low power gear integration module 100 in this embodiment is mainly used in agricultural machinery such as tractors. Power can be transmitted from the input shaft S1 to the intermediate shaft S2, then from the intermediate shaft S2 to the output shaft S3, and finally input to actuators such as the walking system via the output shaft S3. Power transmission between the shafts can be achieved through the engagement of gear sets.

[0023] In this embodiment, the power reversing and high / low gear integration module 100 integrates the forward clutch C1, reverse clutch C2, low gear clutch C3, and high gear clutch C4 via the input shaft S1, intermediate shaft S2, and output shaft S3. This enables four gear modes: low gear forward, high gear forward, low gear reverse, and high gear reverse, meeting various usage requirements. Furthermore, the forward clutch C1 and reverse clutch C2 are sequentially arranged along the axial direction of the input shaft S1 and share a common first outer hub 8, improving the structural compactness of the reversing device. The low gear clutch C3 and high gear clutch C4 are sequentially arranged along the axial direction of the output shaft S3 outside the output shaft S3. The low-gear clutch C3 and high-gear clutch C4 are integrated and share the same second outer hub 9, which further improves the structural compactness of the power reversing and high / low gear integration module 100. The input shaft S1 is connected to the first outer hub 8 via a first connecting frame located between the forward clutch C1 and the reverse clutch C2. The output shaft S3 is connected to the second outer hub 9 via a second connecting frame located between the low-gear clutch C3 and the high-gear clutch C4. The connection method between the input shaft S1, output shaft S3, and clutch outer hubs fully utilizes the axial space of the power reversing and high / low gear integration module 100. In this embodiment, the two clutches share a single outer hub, resulting in a more compact structure. Integrating the clutches on two shafts meets the needs of various application scenarios, and eliminating the need for a clutch on the intermediate shaft S2 reduces the center distance between the input shaft S1 and the output shaft S3, thus improving the space utilization of the power reversing and high / low gear integration module 100 in multiple ways.

[0024] like Figure 1 As shown, the shaft assembly also includes an idler shaft S4 with a reversing idler pulley 4. The axes of the input shaft S1, intermediate shaft S2, output shaft S3, and idler shaft S4 are not coplanar. The reverse clutch C2 is used to transmit power to the intermediate shaft S2 via the reversing idler pulley 4. In this embodiment, the power reversing and high / low gear integrated module 100 is placed in the gearbox of the agricultural machinery. The input shaft S1 inputs power into the gearbox, and the power is transmitted to the intermediate shaft S2 through the gear clutches (C1 / C2), and then to the output shaft S3 through the gear clutches (C3 / C4). At least one of the input shaft S1 and the output shaft S3 is located at the top of the gearbox, which can reduce the oil churning loss of the clutch, thereby reducing the heat power of the gearbox and improving the overall working efficiency.

[0025] In this embodiment, reversing is specifically achieved through an idler shaft S4 with a reversing idler wheel 4. The structure is simple, and the axes of the input shaft S1, intermediate shaft S2, output shaft S3, and idler shaft S4 are not coplanar and are not arranged in the same plane. This allows the power reversing and high / low gear integration module 100 to integrate reversing and high / low gear functions while using a spatial four-axis system (S1-S4) connected in parallel and integrated together. This saves axial dimensions, makes more efficient use of the gearbox space, and effectively compresses axial space dimensions while meeting the requirements of 4 gears, reducing the product's overall size and weight, and saving costs.

[0026] Specifically, the forward clutch C1 engages the forward gear 1, and a first gear 2, which is driven by the forward gear 1, is mounted on the intermediate shaft S2. The reverse clutch C2 engages the reverse gear 5, and a second gear 6, which is driven by the reversing idler wheel 4, is mounted on the intermediate shaft S2. The reversing idler wheel 4 and the reverse gear 5 are also driven by each other. Figure 1 As shown, in this embodiment, the two ends of the intermediate shaft S2 are respectively provided with a first gear 2 and a second gear 6. The first gear 2 is connected to the forward gear 1 through transmission, and the second gear 6 is connected to the reversing idler wheel 4 through transmission. The reverse gear 5 can be driven to the second gear 6 through the reversing idler wheel 4. The reversing power can be transmitted through the intermediate shaft S2. The structure is simple and easy to reverse.

[0027] Furthermore, the power reversing and power high / low gear integrated module 100 includes a low gear 3 that is driven and connected to the first gear 2 and a high gear 7 that is driven and connected to the second gear 6. The low gear clutch is used to engage the low gear 3, and the high gear clutch C4 is used to engage the high gear 7. The transmission ratio between the first gear 2 and the low gear 3 is a first transmission ratio, and the transmission ratio between the second gear 6 and the high gear 7 is a second transmission ratio. The first transmission ratio is greater than the second transmission ratio.

[0028] In this embodiment, the power transmission routes of the power reversing and high / low gear integrated module 100 in the four gear positions are as follows: High gear forward: Forward clutch C1 engages forward gear 1, high gear clutch C4 engages high gear 7, and the power of input shaft S1 is transmitted to intermediate shaft S2 through the meshing of forward gear 1 and first gear 2. The power of intermediate shaft S2 is transmitted to output shaft S3 through the meshing of second gear 6 and high gear 7. High gear reverse: Reverse clutch C2 engages with reverse gear 5, high gear clutch C4 engages with high gear 7, the power of input shaft S1 is transmitted to idler shaft S4 through reverse gear 5 and reversing idler 4, and then to intermediate shaft S2 through reversing idler 4 and second gear 6, and then to output shaft S3 through the engagement of second gear 6 and high gear 7; Low gear forward: Forward clutch C1 engages forward gear 1, low gear clutch C3 engages low gear 3, and the power of input shaft S1 is transmitted to intermediate shaft S2 through the meshing of forward gear 1 and first gear 2. The power of intermediate shaft S2 is transmitted to output shaft S3 through the meshing of first gear 2 and low gear 3. Low gear reverse: Reverse clutch C2 engages reverse gear 5, low gear clutch C3 engages low gear 3, the power of input shaft S1 is transmitted to idler shaft S4 through reverse gear 5 and reversing idler 4, and then through reversing idler 4 and second gear 6 to intermediate shaft S2, the power of intermediate shaft S2 is transmitted to output shaft S3 through first gear 2 and low gear 3.

[0029] In this embodiment, power is transmitted from two gears on the intermediate shaft S2 to two gears in the shifting device, thereby realizing power transmission for different gears. The number of gears is small and the structure is relatively simple.

[0030] In one embodiment, such as Figure 2 and Figure 3 As shown, the input shaft S1 and output shaft S3 are sequentially arranged on the first horizontal plane. The first horizontal plane and the axis of the idler shaft S4 are not coplanar. The intermediate shaft S2 is located between the input shaft S1 and the output shaft S3 in the horizontal direction. In this embodiment, the input shaft S1 and output shaft S3 are located at the top and are sequentially arranged in the horizontal direction (left and right direction). The intermediate shaft S2 is located between the input shaft S1 and the output shaft S3 in the left and right direction. The idler shaft S4 and the intermediate shaft S2 are arranged side by side in the left and right direction. In this embodiment, the horizontal and vertical structure of the power reversing and power high and low gear integration module 100 is relatively compact through the staggered arrangement of the three axes in the vertical and horizontal directions.

[0031] In another embodiment, such as Figure 4 As shown, the axes of the input shaft S1, intermediate shaft S2, output shaft S3, and idler shaft S4 are located in different planes along the vertical direction. In this embodiment, the idler shaft S4 is located at the top, the output shaft S3 is located at the bottom, and the input shaft S1 and intermediate shaft S2 are located in different planes along the vertical direction. Figure 4 The intermediate shaft S2 is located between the idler shaft S4 and the output shaft S3 in the vertical direction, and the intermediate shaft S2 is located in the horizontal direction ( Figure 4 The left and right directions of the intermediate shaft S2 and the idler shaft S4 are located between the input shaft S1 and the idler shaft S4. In this embodiment, the axes of the input shaft S1, the intermediate shaft S2, the output shaft S3, and the idler shaft S4 are located in different planes along the vertical direction, making full use of the horizontal and vertical space of the power reversing and power high and low gear integration module 100.

[0032] It should be noted that two of the axes of the input shaft S1, intermediate shaft S2, output shaft S3, and idler shaft S4 are located in the first plane, and the other two are located in the second plane. The first and second planes are arranged vertically in sequence. Figure 3 As shown, in one embodiment, the power reversing and power high / low gear integration module 100 is in reverse gear, the idler shaft S4 and the intermediate shaft S2 are arranged side by side on one plane, and the input shaft S1 and the output shaft S3 are arranged side by side on another plane and located below the idler shaft S4 and the intermediate shaft S2, which can save the circumferential space (including horizontal and vertical space) of the power reversing and power high / low gear integration module 100.

[0033] In another embodiment, the input shaft S1 and the output shaft S3 are arranged side by side along a second horizontal direction, which is not collinear with the axial direction of the input shaft S1, and the intermediate shaft S2 is located vertically between the input shaft S1 and the output shaft S3. Figure 2 As shown, the power reversing and high / low gear integrated module 100 is in forward gear. The input shaft S1 and output shaft S3 are arranged side-by-side with intervals along the vehicle width direction, and their axes are collinear. The intermediate shaft S2 is located below the input shaft S1 and output shaft S3, and its axis lies between the axes of the input shaft S1 and output shaft S3 along the vehicle width direction. The four clutches are paired and installed on the input shaft S1 and output shaft S3, while the intermediate shaft S2 has no clutches. This spatial arrangement of the input shaft S1, intermediate shaft S2, and output shaft S3 further reduces the distance between the input shaft S1 and output shaft S3, thereby reducing the circumferential dimensions.

[0034] It should be noted that both the forward clutch C1 and the reverse clutch C2 are electro-hydraulic controlled automatic clutches; and both the low-gear clutch and the high-gear clutch C4 are electro-hydraulic controlled automatic clutches. In this embodiment, all four clutches can be electro-hydraulic controlled automatic clutches, and the engagement and disengagement of the four clutches (C1-C4) can be achieved through an existing electro-hydraulic control system. Specifically, when shifting from a low gear to a high gear, under the control of the electro-hydraulic system, the low-gear clutch C3 slowly disengages and the high-gear clutch C4 slowly engages. This disengagement and engagement ensures continuous and uninterrupted power input during gear shifting, allowing for four-gear switching without power interruption, greatly improving the driver's driving experience.
