[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0036] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] like Figure 1As shown, this embodiment of the present invention provides a torque converter and transmission assembly, including an engine 10, a torque converter, a transmission, an input shaft 40, and an output shaft 90. The torque converter includes a shroud 21, a pump wheel 22, a turbine 23, a guide wheel 24, and a one-way clutch assembly 25. The shroud 21 is connected to the engine 10, the pump wheel 22 is connected to the shroud 21, and the turbine 23 is connected to the input shaft 40. The one-way clutch assembly 25 is configured to lock the guide wheel 24 or cause the guide wheel 24 to rotate in one direction. The input component of the transmission is connected to the input shaft 40, and the output component of the transmission is connected to the output shaft 90. The engine 10 transmits power to the shroud 21, which drives the pump wheel 22. The pump wheel 22 converts mechanical energy into kinetic energy of the oil through oil circulation, causing the oil to impact the turbine 23. The turbine 23 absorbs the kinetic energy of the oil and converts it back into mechanical energy. The turbine 23 transmits the power to the transmission via the input shaft 40, and then, after being reduced in speed by the transmission, transmits it to the output shaft 90. Due to the function of the one-way clutch assembly 25, when the turbine 23 rotates at a low speed, the one-way clutch assembly 25 locks the guide wheel 24. The guide wheel 24 can reflect the oil back to the pump wheel 22 at a suitable angle, increasing the torque output of the pump wheel 22 and playing a role in increasing torque. When the turbine 23 rotates to a certain speed, the direction of the impact force of the oil on the guide wheel 24 changes. At this time, the one-way clutch assembly 25 unlocks the guide wheel 24, and the guide wheel 24 can rotate in one direction, thereby avoiding energy loss caused by the guide wheel 24 obstructing the flow of oil.

[0040] The torque converter and gearbox assembly provided in this embodiment of the utility model has a turbine 23 that is directly connected to the input component of the gearbox via an input shaft 40. This eliminates the need for a primary input gear, a secondary input gear, and an overrunning clutch, improving the compactness of the structure and making it suitable for vehicles with limited space. It also shortens the power transmission path, improves power transmission efficiency, and reduces noise sources. In addition, a one-way clutch assembly 25 is provided for the guide wheel 24, which reduces energy consumption and improves efficiency.

[0041] Continue to refer to Figure 1In this embodiment, the gearbox includes a sun gear 51, a first-gear planetary gear carrier 52, a first-gear ring gear 53, a reverse-gear planetary gear carrier 54, a reverse-gear ring gear 55, an output drive gear 56, an output driven gear 57, a first-gear clutch 61, a second-gear clutch 62, and a reverse-gear clutch 63. The sun gear 51 is fixedly sleeved on the input shaft 40. The first-gear planetary gear carrier 52 and the reverse-gear planetary gear carrier 54 are both meshed with the sun gear 51. The first-gear ring gear 53 meshes with the first-gear planetary gear carrier 52, and the reverse-gear ring gear 55 meshes with the reverse-gear planetary gear carrier. The first gear planetary gear carrier 52 is connected to the reverse gear ring gear 55. The first gear clutch 61 is used to control the locking and unlocking of the first gear ring gear 53, and the reverse gear clutch 63 is used to control the locking and unlocking of the reverse gear planetary gear carrier 54. Part of the second gear clutch 62 is connected to the sun gear 51, and the other part of the second gear clutch 62 is connected between the first gear planetary gear carrier 52 and the output drive gear 56. The output driven gear 57 is meshed with the output drive gear 56, and the output driven gear 57 is fixedly sleeved on the output shaft 90. When the transmission is in first gear, the first gear clutch 61 locks the first gear ring gear 53. At this time, the power from the input shaft 40 is transmitted sequentially to the output shaft 90 via the sun gear 51, the first gear planetary gear carrier 52, the second gear clutch 62, the output drive gear 56, and the output driven gear 57. When the transmission is in second gear, the second gear clutch 62 is engaged (i.e., both parts of the second gear clutch 62 are engaged). At this time, the power from the input shaft 40 is transmitted sequentially to the output shaft 90 via the sun gear 51, the second gear clutch 62, the output drive gear 56, and the output driven gear 57. When the transmission is in reverse gear, the reverse gear clutch 63 locks the reverse gear planetary gear carrier 54. The power from the input shaft 40 is transmitted sequentially to the output shaft 90 via the sun gear 51, the reverse gear ring gear 55, the first gear planetary gear carrier 52, the second gear clutch 62, the output drive gear 56, and the output driven gear 57. In other embodiments, the transmission may also be a fixed-shaft structure, and is not limited to this embodiment.

[0042] Continue to refer to Figure 1 The torque converter and gearbox assembly provided in this embodiment also includes an input speed sensor 71 and an output speed sensor 72. The input speed sensor 71 is used to detect the rotational speed of the input shaft 40, and the output speed sensor 72 is used to detect the rotational speed of the output shaft 90. Based on the detection results of the input speed sensor 71 and the output speed sensor 72, it is possible to determine whether the clutches of each gear are functioning properly, thereby achieving the purpose of real-time monitoring of the gearbox's operating status. In this embodiment, a speed gear 80 is provided on the input shaft 40, the input speed sensor 71 is positioned directly opposite the speed gear 80, and the output speed sensor 72 is positioned directly opposite the output drive gear 56. Combined with... Figure 7 As shown, both the input speed sensor 71 and the output speed sensor 72 are fixed to the gearbox housing 200. Further, referring to... Figure 7The torque converter and transmission assembly provided in this embodiment also includes a first gear pressure sensor 301 and a reverse gear pressure sensor 302. The first gear pressure sensor 301 can monitor the working pressure of the transmission in first gear, and the reverse gear pressure sensor 302 can monitor the working pressure of the transmission in reverse gear. The first gear pressure sensor 301 and the reverse gear pressure sensor 302 can monitor the working status of the transmission in real time, thereby monitoring the working status of the transmission together with the input speed sensor 71 and the output speed sensor 72, improving the accuracy of monitoring.

[0043] Continue to refer to Figure 1 The torque converter and gearbox assembly provided in this embodiment also includes a power take-off (PTO) assembly, which includes a transfer gear 31, a PTO gear 32, and a PTO shaft 33. The transfer gear 31 is connected to the pump wheel 22, the PTO gear 32 meshes with the transfer gear 31, and the PTO shaft 33 is connected to the PTO gear 32. The PTO shaft 33 can serve as a power source for other mechanisms. In this embodiment, there are two PTO gears 32 and two PTO shafts 33. Both PTO gears 32 mesh with the transfer gear 31, and the two PTO shafts 33 are connected to the two PTO gears 32 in a one-to-one correspondence. In this embodiment, combined with... Figures 5 to 7 As shown, one of the power take-off shafts 33 is connected to the variable speed pump 34, and the other power take-off shaft 33 is connected to the mounting flange 35. Of course, the two power take-off shafts 33 can also be connected to other mechanisms, and are not limited to this embodiment.

[0044] like Figure 2 As shown, in this embodiment, the torque converter also includes a housing 101, within which the shroud 21, pump wheel 22, turbine 23, and guide wheel 24 are all housed. The turbine 23 is connected to the turbine hub 231 to form a turbine assembly, which is mounted on the shroud 21 via a first bearing 115. The guide wheel 24 is mounted on a guide wheel seat 112 via a one-way clutch assembly 25. The guide wheel seat 112 is connected to the housing 101 via a fourth bolt 113 or other fasteners. The pump wheel 22 and the transfer gear 31 are mounted on the guide wheel seat 112 via a second bearing 114.

[0045] Continue to refer to Figure 2In this embodiment, the torque converter further includes a mounting plate 102, an input flange 103, an end cover 105, a connecting sleeve 108, a third bearing 110, and an oil seal 111. The mounting plate 102 is used to mount the engine 10. The mounting plate 102 is connected to the input flange 103 by a first bolt 104 or other fasteners. The input flange 103 is fitted onto the outer periphery of the end cover 105, and the input flange 103 and the end cover 105 are fastened together by a second bolt 106 or other fasteners. A sealing ring 107 is provided between the input flange 103 and the end cover 105. The end cover 105 is connected to the cover wheel 21 by a third bolt 109 or other fasteners. The connecting sleeve 108 is fitted onto the end cover 105 and... The outer periphery of the input flange 103 is connected to the housing 101. A third bearing 110 is provided between the inner peripheral wall of the connecting sleeve 108 and the outer peripheral wall of the end cover 105. An oil seal 111 is provided between the inner peripheral wall of the connecting sleeve 108 and the outer peripheral wall of the input flange 103. The connecting sleeve 108, end cover 105, input flange 103, oil seal 111, sealing ring 107, and mounting plate 102 together seal the side of the housing 101 facing the engine 10. That is, the connecting sleeve 108, end cover 105, input flange 103, oil seal 111, sealing ring 107, and mounting plate 102 form a dry assembly, preventing oil in the housing 101 from flowing out from the side facing the engine 10. Through the above configuration, the torque converter is transformed into a dry torque converter, preventing oil from flowing into the connection cavity between the engine 10 and the torque converter, thereby reducing oil churning losses. Furthermore, the third bearing 110 can cooperate with the second bearing 114 to support the torque converter at the front and rear of the torque converter, respectively. The bearing is subjected to uniform force and has high reliability.

[0046] like Figure 3 As shown, the end cap 105 is further provided with a lubrication hole 1051, which is used to guide the oil in the housing 101 to the third bearing 110 and the oil seal 111 to lubricate the third bearing 110 and the oil seal 111, thereby reducing the wear of the third bearing 110 and the oil seal 111.

[0047] like Figure 4 As shown, in this embodiment, the one-way clutch assembly 25 includes a one-way clutch 251, an inner ring 252, an outer ring 253, and two clutch bearings 254. The one-way clutch 251 is located between the inner ring 252 and the outer ring 253, and the two clutch bearings 254 are located between the inner ring 252 and the outer ring 253, and are located on both sides of the one-way clutch 251 along the axial direction of the one-way clutch 251, which has a simple structure.

[0048] like Figure 7 As shown, the outer side of the housing 101 and the gearbox housing 200 is provided with topological reinforcing ribs 400. By providing topological reinforcing ribs 400, the structural strength can be enhanced, vibration can be reduced, and noise can be further reduced.

[0049] like Figures 8 to 10 As shown, a control valve 500 is provided on the gearbox housing 200, which is used to control the gear shifting of the gearbox. Specifically, a valve mounting surface 201 is provided on the gearbox housing 200, and a first gear oil inlet a2011, a second gear oil inlet a2012, and a reverse gear oil inlet a2013 are provided on the valve mounting surface 201. A first gear oil inlet b501, a second gear oil inlet b502, and a reverse gear oil inlet b503 are provided on the control valve 500. The first gear oil inlet b501 is opposite to the first gear oil inlet a2011 to form the first gear oil inlet, the second gear oil inlet b502 is opposite to the second gear oil inlet a2012 to form the second gear oil inlet, and the reverse gear oil inlet b503 is opposite to the reverse gear oil inlet a2013 to form the reverse gear oil inlet. When the transmission is in first gear, oil enters through the first gear inlet, engaging the first gear clutch 61; when the transmission is in second gear, oil enters through the second gear inlet, engaging the second gear clutch 62; when the transmission is in reverse gear, oil enters through the reverse gear inlet, engaging the reverse gear clutch 63. This embodiment simplifies the arrangement of the valve mounting surface 201 and the oil ports of the control valve 500, and also simplifies the oil passage arrangement within the housing 200 and the valve body, simplifying the structure and reducing costs.

[0050] In addition, the valve mounting surface 201 is also provided with a torque converter inlet a2014 and a torque converter return port a2015, and the control valve 500 is also provided with a torque converter inlet b504, a torque converter return port b505 and a valve inlet 506.
