Description

Technical Field

[0001] The utility model relates to the technical field of tractor clutches, in particular to a wet dual-action clutch assembly. Background Art

[0002] The clutch is one of the components with the highest failure rate on domestic tractors. Currently, most of the clutches on existing large and medium-horsepower tractors are dual-action clutches, including two driven disc assemblies. Among them, the main driven disc assembly is responsible for traveling, and the secondary driven disc assembly is responsible for power output. If the tractor is performing traction operations such as plowing, the friction plates on the main driven disc assembly responsible for traveling are easily ablated; if the tractor is performing power output operations such as rotary tillage, the friction plates of the secondary driven disc assembly responsible for power output are easily ablated. The ablation of the clutch is mainly caused by the slip friction of the clutch, resulting in a long-term friction state between the driven disc assembly and the cover assembly. During the friction process, a high temperature above 350°C will be generated instantaneously. Currently, the temperature critical value of the commonly used dry friction plates is about 350°C, so it is very easy to cause the burning of the plates.

[0034] In order to make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation mode of the present utility model will be given in conjunction with the accompanying drawings.

[0035] In the following description, specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific implementation modes disclosed below.

[0036] Embodiment 1

[0037] As Figure 1 and Figure 2 shown, the wet double-acting clutch assembly in this embodiment includes an outer ring 4, an oil cylinder flywheel disc 1 and a clutch flywheel disc 6. The outer ring 4, the oil cylinder flywheel disc 1 and the clutch flywheel disc 6 form a chamber, and the oil-resistant friction part combination and the internal gear disc hub 10 are located in this chamber. The internal gear disc hub 10 is connected to the walking shaft, and the walking of the tractor can be realized by the rotation of the walking shaft. The oil cylinder flywheel disc 1 is connected to the spline shaft, and the spline shaft is connected to the external power output shaft. The function of the power output shaft of the tractor can be realized by the rotation of the spline shaft.

[0038] One side of the outer circle end face of the outer ring 4 is fixedly connected to the oil cylinder flywheel disc 1, and a first O-ring 3 is provided at the connection surface between the outer ring 4 and the oil cylinder flywheel disc 1. The outer circle end face of the other side of the outer ring 4 is fixedly connected to the clutch flywheel disc 6, and a second O-ring 5 is provided at the connection surface between the outer ring 4 and the clutch flywheel disc 6. The outer circle end face of one side of the clutch flywheel disc 6 is fixedly connected to the outer ring 4, and the axial side face of the other side of the clutch flywheel disc 6 is fixedly connected to the bearing sleeve 8, and the bearing sleeve 8 plays a role in driving the oil pump. In this embodiment, the clutch flywheel disc 6 and the bearing sleeve 8 are fixedly connected by a fifth hexagon socket head cap screw 19.

[0039] In this embodiment, the oil cylinder flywheel disc 1, the outer ring 4 and the clutch flywheel disc 6 are fixedly connected by an eighth hexagon socket head cap screw 35.

[0040] In this embodiment, an oil cylinder groove is provided at the axial side face of the oil cylinder flywheel disc 1 facing the clutch flywheel disc, and the oil cylinder piston 2 is slidably arranged in the oil cylinder groove. A fourth O-ring 28 is provided between the annular outer wall of the oil cylinder piston 2 and the side wall of the adjacent oil cylinder groove, and a third O-ring 16 and a guide band 34 are provided between the annular inner wall of the oil cylinder piston 2 and the side wall of the adjacent oil cylinder groove. The fourth O-ring 28 and the third O-ring 16 play a role in sealing the oil cylinder groove, and the guide band 34 plays a role in guiding the reciprocating movement of the oil cylinder piston 2.

[0041] The oil-resistant friction part combination is located between the oil cylinder piston 2 and the clutch flywheel disc 6, and a pressure plate 18 is provided between the oil-resistant friction part combination and the oil cylinder piston 2, and a return spring 23 is connected between the pressure plate 18 and the outer ring 4. When the oil cylinder piston 2 moves towards the oil-resistant friction part combination, the extrusion force is transmitted to the oil-resistant friction part combination through the pressure plate 18, and at the same time, the return spring 23 between the pressure plate 18 and the outer ring 4 is compressed.

[0042] Hydraulic oil channels are provided in the clutch flywheel disc 6, the outer ring 4 and the oil cylinder flywheel disc 1, and the hydraulic oil channels are communicated with each other. A hydraulic oil inlet and outlet is provided in the clutch flywheel disc 6, one end of the hydraulic oil channel is communicated with the hydraulic oil inlet and outlet, and the other end of the hydraulic oil channel is communicated with the oil cylinder groove. The hydraulic oil flows into the oil cylinder groove through the hydraulic oil inlet and outlet. At this time, the hydraulic pressure exerted by the hydraulic oil on the oil cylinder piston 2 pushes the oil cylinder piston 2 towards the pressure-resistant friction part combination, and squeezes the pressure-resistant friction part combination, realizing the engagement of the clutch. Or the hydraulic oil flows out of the oil cylinder groove through the hydraulic oil inlet and outlet. At this time, the extrusion force exerted by the oil cylinder piston 2 on the pressure-resistant friction part combination is removed, realizing the separation of the clutch.

[0043] The first oil-resistant friction member assembly includes several steel sheets 21 and several paper-based sheets 20. The steel sheets 21 and the paper-based sheets 20 are arranged at staggered intervals along the axial direction of the clutch assembly. The paper-based sheets are provided on one or both sides of the steel sheets. There are paper-based sheets both between the oil-resistant friction member assembly and the clutch pressure plate 18, and between the oil-resistant friction member assembly and the clutch flywheel disc 6.

[0044] External teeth are provided at the outer edge of the steel sheet 21. The steel sheet 21 is connected to the outer ring 4 through its external teeth. Therefore, when the outer ring 4 rotates, it drives the steel sheet 21 to rotate. At the same time, the steel sheet can also move axially along the outer ring 4. Separation springs 22 are provided between the outer edges of adjacent steel sheets. When the clutch is in the separated state, the separation springs 22 can ensure that the distances between adjacent steel sheets are the same, preventing uneven spacing between the steel sheets.

[0045] Internal teeth are provided at the inner edge of the paper-based sheet 20. The paper-based sheet 20 is connected to the external teeth 7 through its internal teeth. Therefore, when the paper-based sheet 20 rotates, it drives the external teeth 7 to rotate. An internal tooth disc hub 10 is provided in the central hole of the external teeth 7. The outer circle of the external teeth 7 is connected to the paper-based sheet 20, and the inner circle end face of the external teeth 7 is fixedly connected to the internal tooth disc hub 10 through the first rivet 9. The internal tooth disc hub 10 is connected to the walking shaft through a spline. When the clutch is in the engaged state, the paper-based sheet 20 drives the external teeth 7 and the internal tooth disc hub 10 to rotate, and the rotation of the walking shaft is achieved through the spline connection.

[0046] The oil cylinder flywheel disc 1 and the internal tooth disc hub 10 are connected through a deep groove ball bearing 14. In this embodiment, the outer ring of the deep groove ball bearing 14 is fixedly connected to the oil cylinder flywheel disc 1 through the second hexagon socket head cap screw 13, and the inner ring of the deep groove ball bearing 14 is fixedly connected to the internal tooth disc hub 10 through the third hexagon socket head cap screw 15. Through the deep groove ball bearing 14, the concentricity between the oil cylinder flywheel disc 1 and the internal tooth disc hub 10 is ensured.

[0047] A clutch flywheel disc 6 is provided with a circulating oil passage 37. A clutch circulating oil cover 11 is fixedly arranged at intervals on the axial side of the clutch flywheel disc 6 facing the oil cylinder flywheel disc 1. In this embodiment, the clutch circulating oil cover 11 is fixedly connected to the clutch flywheel disc 6 through a first hexagon socket head cap screw 12. A plurality of oil outlet grooves are arranged on the surface of the clutch circulating oil cover 11 facing the oil-resistant friction part combination. A circulating oil cavity is formed between the clutch circulating oil cover 11 and the clutch flywheel disc 6. The clutch flywheel disc 6 is provided with a circulating oil inlet, and a plug screw 30 is arranged at the circulating oil inlet. One end of the circulating oil passage 37 is communicated with the circulating oil inlet, and the other end of the circulating oil passage 37 is communicated with the circulating oil cavity. A first throttle plug screw 29 is arranged at the communicating place between the circulating oil passage 37 and the circulating oil cavity, and the circulating oil flowing into the oil-resistant friction part combination is depressurized and throttled through the first throttle plug screw 29. After the circulating oil flows into the circulating oil cavity through the circulating oil passage 37, it flows into the oil-resistant friction part combination along the oil outlet grooves. After the circulating oil enters the oil-resistant friction part combination, during the flowing process of the circulating oil, the heat in the oil-resistant friction part combination is carried away, playing a cooling role for the oil-resistant friction part combination.

[0048] A spline hole 48 is arranged in the middle of the axial side of the oil cylinder flywheel disc 1 facing the clutch flywheel disc 6. A spline shaft is arranged in the spline hole 48, and the spline shaft is connected to an external power output shaft. During the rotation process of the whole clutch assembly, the oil cylinder flywheel disc 1 drives the external power output shaft to rotate through the spline shaft, thus realizing the function of the power output shaft of the tractor.

[0049] The oil cylinder flywheel disc 1 and the pressure plate 18 are connected through a transmission piece 27. Therefore, during the rotation process of the oil cylinder flywheel disc 1, the pressure plate 18 can be driven to rotate synchronously. Specifically, the transmission piece 27 is strip-shaped. One end of the transmission piece 27 is connected to the outer circular end face of the oil cylinder flywheel disc 1 through a sixth hexagon socket head cap screw 24, and a first bolt seat 26 is sleeved outside the sixth hexagon socket head cap screw 24. One side end part of the transmission piece 27 is arranged between the first bolt seat 26 and the oil cylinder flywheel disc 1, and a first spring washer 25 is arranged between the first bolt seat 26 and the sixth hexagon socket head cap screw 24. Correspondingly, the other end of the transmission piece 27 is connected to the pressure plate 18 through a seventh hexagon socket head cap screw 33. A second bolt seat is sleeved outside the seventh hexagon socket head cap screw 33. The other side end part of the transmission piece 27 is located between the second bolt seat and the pressure plate 18, and a second spring washer 31 is arranged between the second bolt seat and the seventh hexagon socket head cap screw 33. Through the above connection method, the connection between the oil cylinder flywheel disc 1 and the pressure plate 18 can be realized, and the reciprocating movement of the pressure plate 18 along the axis will not be affected.

[0050] During the operation of the clutch assembly, when the clutch is in the engaged state, hydraulic oil with oil pressure enters the hydraulic oil passage 36. Through the pressure of the hydraulic oil, the cylinder piston 2 is pushed to move towards the oil-resistant friction part assembly, pressing the pressure plate 18, the oil-resistant friction part assembly, and the clutch flywheel disc 6 tightly against each other. The torque of the engine is transmitted through the clutch flywheel disc 6 and the pressure plate 18 to the oil-resistant friction part assembly, and then through the internal gear hub 10 to the travel shaft. During the process of being tightly pressed against each other, the return spring 23 between the pressure plate 18 and the outer ring 4 is compressed, and elastic forces are generated in both the return spring 23 and the release spring 22.

[0051] When the clutch is disengaged, the oil pressure of the hydraulic oil supplied to the cylinder piston 2 is removed, and the return spring 23 and the release spring 22 gradually return to their original positions. At this time, the pressure plate 18 moves away from the oil-resistant friction part assembly, creating a gap between the pressure plate 18, the oil-resistant friction part assembly, and the clutch flywheel disc 6. The frictional torque acting on the oil-resistant friction part assembly disappears, interrupting the power transmission. By repeating the above processes of the engaged state and the disengaged state, the operation process of the clutch assembly is realized.

[0052] Meanwhile, the circulating oil enters the oil-resistant friction part assembly through the circulating oil passage 37 and the oil outlet holes on the clutch circulating oil cover. At this time, the circulating oil fills the space between the paper base sheet 20 and the steel sheet 21, forming an oil-based friction between the paper base sheet 20 and the steel sheet 21, and at the same time, the temperature generated by the friction between the paper base sheet 20 and the steel sheet 21 can be reduced.

[0053] Embodiment 2

[0054] As Figure 3 and Figure 4 shown, a groove is provided at the axial side of the clutch flywheel disc 6 facing the cylinder flywheel disc 1 in this embodiment, and the cylinder piston 2 is slidably arranged in the groove. The oil-resistant friction part assembly is arranged between the cylinder piston 2 and the cylinder flywheel disc 1, and a pressure plate 18 is provided between the cylinder piston 2 and the oil-resistant friction part assembly. When the clutch is engaged, the cylinder piston 2 presses the pressure plate 18, the oil-resistant friction part assembly, and the cylinder flywheel disc 1 tightly against each other.

[0055] Several clutch circulating oil conduits 39 are fixedly arranged at intervals on the axial side of the clutch flywheel disc 6 facing the cylinder flywheel disc 1. The clutch circulating oil conduits 39 are communicated with the circulating oil passage 37. A circulating oil inlet is provided in the clutch flywheel disc 6. One end of the circulating oil passage 37 is communicated with the circulating oil inlet, and the other end of the circulating oil passage 37 is communicated with the clutch circulating oil conduits 39. The circulating oil flows into the clutch circulating oil conduits 39 through the circulator passage 37. Several oil outlet grooves are arranged at intervals on the surface of the clutch circulating oil conduits 39 facing the oil-resistant friction part assembly. The circulating oil entering the clutch circulating oil conduits flows into the oil-resistant friction part assembly through the oil outlet grooves. In this embodiment, the clutch circulating oil conduits 39 are fixedly connected to the clutch flywheel disc 6 through nuts 38.

[0056] The rest is the same as in Embodiment 1.

[0057] In this application, the position of the oil cylinder piston 4 is not limited to the positions described in Embodiment 1 and Embodiment 2. The oil cylinder piston can also be arranged at an appropriate position in the chamber composed of the outer ring 4, the oil cylinder flywheel disc 1 and the clutch flywheel disc 6. The output end of the oil cylinder piston is fixedly connected to the push plate, and the push plate contacts the pressure plate. At this time, the oil-resistant friction part combination can be located between the pressure plate and the clutch flywheel disc 6, or between the pressure plate and the oil cylinder flywheel disc 1.

[0058] Embodiment 3

[0059] As Figure 5 shown, in this embodiment, a shield 42 is provided on the outer sides of the outer ring 4 and the clutch flywheel disc 6. There is a gap between the annular outer walls of the outer ring 4 and the clutch flywheel disc 6 and the inner wall of the adjacent shield 42, and inclined circulating oil guide vanes are provided in this gap. There is a gap between the axial side surface of the clutch flywheel disc 6 facing away from the oil cylinder flywheel disc 1 and the axial inner wall of the adjacent shield, and an oil guide wheel 43 is provided in this gap. The oil guide wheel 43 is communicated with the circulating oil outlet.

[0060] The outer circular end surface of the shield 42 is fixedly connected to the outer ring end surface of the oil cylinder flywheel disc 1 through the ninth inner hexagon bolt 40, and an oil cylinder flywheel disc gasket 41 is provided at the connection between the shield 42 and the oil cylinder flywheel disc 1. A bearing sleeve 8 is provided in the central hole of the shield 42. The bearing sleeve 8 is fixedly connected to the shield 42 through the third rivet 45, and a fifth O-ring 44 and a sixth O-ring 46 are provided at the connection surface between the bearing sleeve 8 and the shield 42.

[0061] As the entire clutch assembly rotates, the circulating oil in the oil-resistant friction part combination is thrown out to the outside of the outer ring and lands on the circulating oil guide vanes. Under the guiding action of the circulating oil guide vanes, the circulating oil converges and flows into the outside of the oil guide wheel 43, and the circulating oil is guided to the circulating oil outlet and discharged through the oil guide wheel 43. The discharged circulating oil can enter the clutch assembly again, realizing the reuse of the circulating oil.

[0062] A second oil guide vane is provided on the inner wall surface of the bearing sleeve 8 and near the circulating oil outlet, which makes it more convenient to guide the circulating oil in the oil guide wheel.

[0063] The rest is the same as in Embodiment 1.

The axial side of the oil cylinder flywheel disc 1 facing away from the clutch flywheel disc 6 is fixedly connected to the flexible disc. During the rotation of the flexible disc, the oil cylinder flywheel disc 1 is driven to rotate. In Embodiment 1, however, the oil cylinder flywheel disc is driven to rotate through the spline connection between the oil cylinder flywheel disc and the shock absorber.

[0066] Others are the same as Embodiment 3.

[0067] The oil cylinder flywheel discs in the above-mentioned Embodiment 1 and Embodiment 2 can also be driven to rotate by the flexible disc.
