[0056] 500, rear axle module. DETAILED DESCRIPTION

[0057] The following will describe in detail the specific embodiments of the present application with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining and understanding the present application, and are not used to limit the present application.

[0058] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0059] Please refer to Figure 1 and Figure 2 , this embodiment provides a transmission system assembly, which can be applied to working machinery, especially working machinery in the agricultural field.

[0060] The transmission system assembly provided in this embodiment includes a 32F + 32R transmission module 100 and a power take-off module 400. Among them, both the 32F + 32R transmission module 100 and the power take-off module 400 are used for driving connection with the power supply module 200 in the working machinery. Among them, in this embodiment, the 32F + 32R transmission module 100 is used to transmit power to the rear axle module 500 in the working machinery, and the power take-off module 400 is used to transmit power to the upper-mounted equipment of the working machinery.

[0061] In this way, the power of the power supply module 200 can be transmitted along two routes. One route is to directly transmit to the power take-off module 400, and then the power take-off module 400 transmits it to the upper-mounted equipment of the working machinery. The other route is to transmit through the 32F + 32R transmission module 100 to the rear axle module 500 in the working machinery. Among them, the 32F + 32R transmission module 100 can provide 32 forward gear speeds and 32 reverse gear speeds for the traveling equipment of the working machinery, realizing the diversity of the speed spectrum.

[0062] The 32F + 32R transmission module 100 includes a shuttle shift module 110, a main transmission shift module 120, a sub-transmission shift module 130, and a creeper gear module 140 that are sequentially drivingly connected. The shuttle shift module 110 has a first input shaft 111, and the first input shaft 111 is used for driving connection with the power supply module 200 in the working machinery through the first clutch 300. The creeper gear module 140 has a first output shaft 141, and the first output shaft 141 is used for driving connection with the differential of the rear axle module 500.

[0063] Among them, the power take-off module 400 includes a second input shaft 410 and a power take-off transmission module 420. One end of the second input shaft 410 is drivingly connected to the input end of the power take-off transmission module 420, and the other end sequentially passes through the creeper gear module 140, the sub-transmission shift module 130, the main transmission shift module 120, and the shuttle shift module 110 and is used for driving connection with the power supply module 200.

[0064] In the transmission system assembly provided in this embodiment, the 32F + 32R transmission module 100 is drivingly connected to the power supply module 200 in the working machine through the first input shaft 111 of the shuttle shift module 110 via the first clutch 300. Then, power transmission is achieved through the sequentially drivingly connected shuttle shift module 110, main transmission shift module 120, auxiliary transmission shift module 130, and creep shift module 140. Finally, the power is output outward through the creep shift module 140. Thus, through the gear combinations in the shuttle shift module 110, main transmission shift module 120, auxiliary transmission shift module 130, and creep shift module 140, a transmission route layout with 32 forward gear speeds and 32 reverse gear speeds is constructed, increasing the number of gear positions and enhancing the diversity of the speed spectrum. When applied to a working machine, continuous adjustment of tillage and transportation can be achieved, with higher fuel economy. At the same time, the adaptability of the working machine to different working conditions is improved, thereby solving the problems of insufficient existing gear density and low reverse efficiency. Moreover, the power take-off module 400 and the 32F + 32R transmission module 100 are integrated. Both the power take-off module 400 and the 32F + 32R transmission module 100 are used to output power outward, thereby achieving diversity in power output to meet the walking and working requirements of the working machine.

[0065] To more clearly describe the technical solution of this application, the transmission system assembly provided in this embodiment will be elaborated below, specifically as follows:

[0066] Please refer to Figure 1 and Figure 2 In this embodiment, the shuttle shift module 110, main transmission shift module 120, auxiliary transmission shift module 130, and creep shift module 140 in the 32F + 32R transmission module 100 are integrated as separate modules. The shuttle shift module 110, main transmission shift module 120, auxiliary transmission shift module 130, and creep shift module 140 are arranged in sequence along a straight line direction, and the connection between two adjacent modules is detachable. For example, the connection between the shells of the modules is realized by bolts for detachable connection.

[0067] It can be understood that the modular setting is adopted in the 32F + 32R transmission module 100, and the connection between each module is detachable. During subsequent maintenance and repair, it is more convenient, reducing the maintenance time and cost and improving the operation efficiency.

[0068] The shuttle shift module 110 has switchable forward and reverse gears. Both the main transmission shift module 120 and the auxiliary transmission shift module 130 have four switchable speed gears. The creep shift module 140 has two switchable creep gears. In this way, the 32F + 32R transmission module 100 constructs a layout of 2×4×4×2 gears, and further realizes a transmission route layout with 32 forward gear speeds and 32 reverse gear speeds, with a diverse speed spectrum.

[0069] Specifically, the above shuttle shift module 110 further includes a shuttle shift mechanism 112 and a first intermediate transmission mechanism 113. The shuttle shift mechanism 112 includes a forward gear 1120, a shuttle synchronizer 1121, and a reverse gear 1122 arranged in sequence along the axial direction of the first input shaft 111. The reverse gear 1122 is rotatably arranged on the first input shaft 111, and the forward gear 1120 is in transmission connection with the input end in the main transmission gear module 120.

[0070] The first intermediate transmission mechanism 113 is rotatably arranged in the shuttle shift module 110 and is in meshing transmission with the reverse gear 1122 and the forward gear 1120 respectively.

[0071] Wherein, a shuttle transmission gear 111a meshing with the shuttle synchronizer 1121 is provided on the first input shaft 111. The shuttle synchronizer 1121 enables the shuttle transmission gear 111a to be selectively in transmission connection with the reverse gear 1122 or the forward gear 1120 by executing gear shifting between the forward gear position and the reverse gear position. That is to say, when the shuttle synchronizer 1121 is switched to the forward gear position, the shuttle transmission gear 111a is in transmission connection with the forward gear 1120 through the shuttle synchronizer 1121. At this time, the power of the first input shaft 111 is directly transmitted to the main transmission gear module 120 through the forward gear 1120. When switched to the reverse gear position, the shuttle transmission gear 111a is in transmission connection with the reverse gear 1122 through the shuttle synchronizer 1121. At this time, the power of the first input shaft 111 passes through the reverse gear 1122 and the first intermediate transmission mechanism 113, and then is transmitted to the main transmission gear module 120 by the forward gear 1120, and the rotation direction of the forward gear 1120 changes.

[0072] It can be understood that the forward gear 1120, the reverse gear 1122, and the first intermediate transmission mechanism 113 jointly construct the forward gear position and the reverse gear position of the shuttle shift module 110, and it is defined that when the shuttle synchronizer 1121 only meshes with the shuttle transmission gear 111a, the shuttle shift module 110 does not transmit power outward, which is the neutral gear state.

[0073] In this embodiment, the first intermediate transmission mechanism 113 can be selected as a double gear structure. In some embodiments, the first intermediate transmission mechanism 113 can also be implemented by two independent gears fixedly installed on the transmission shaft.

[0074] This embodiment takes the first intermediate transmission mechanism 113 as a double gear structure as an example for illustration. Specifically, the first intermediate transmission mechanism 113 includes a first linkage gear 1130 and a second linkage gear 1131, and the first linkage gear 1130 and the second linkage gear 1131 are connected as a whole through a connecting body. A countershaft is further provided in the housing of the shuttle shift module 110. Wherein, the connecting body in the double gear structure is rotatably arranged on the countershaft.

[0075] Please refer to Figure 3 as well. The above-mentioned main transmission gearshift module 120 includes a first transmission shaft 121, a second transmission shaft 122, a first main transmission gearshift mechanism 123, and a second main transmission gearshift mechanism 124. The first transmission shaft 121 and the second transmission shaft 122 are arranged in parallel. The first transmission shaft 121 is drivingly connected to the output end of the shuttle shift module 110. Specifically, the first transmission shaft 121 is drivingly connected to the forward gear 1120 located at the output end of the shuttle shift module 110, such as a detachable connection method like key connection, flange connection, or coupling connection.

[0076] Furthermore, one end of the first transmission shaft 121 close to the shuttle shift module 110 is sleeved on the first input shaft 111 and is rotationally matched with the first input shaft 111 through a bearing, so as to improve the coaxiality of the installation.

[0077] In this embodiment, the first transmission shaft 121 is provided with a first main transmission gear 121a, a second main transmission gear 121b, and a first main transmission gearshift mechanism 123 arranged in sequence along its own axial direction. Among them, the first main transmission gear 121a and the second main transmission gear 121b are fixedly installed on the first transmission shaft 121 and can rotate synchronously with the first transmission shaft 121. The second transmission shaft 122 is drivingly connected to the input end of the auxiliary transmission gearshift module 130. The second transmission shaft 122 is provided with a second main transmission gearshift mechanism 124, a third main transmission gear 122a, and a fourth main transmission gear 122b arranged in sequence along its own axial direction. Among them, the third main transmission gear 122a and the fourth main transmission gear 122b are fixedly installed on the second transmission shaft 122 and can rotate synchronously with the second transmission shaft 122. The first main transmission gearshift mechanism 123 and the second main transmission gearshift mechanism 124 are arranged in a staggered manner, which can effectively save the installation space, making the main transmission gearshift module 120 more compact in structure and smaller in volume.

[0078] The first main transmission gearshift mechanism 123 is used to selectively transmit the power of the first transmission shaft 121 to the second transmission shaft 122. Among them, the first main transmission gearshift mechanism 123 has two output sides, and the two output sides are respectively meshed and driven with the corresponding third main transmission gear 122a and fourth main transmission gear 122b, and the meshing transmission ratios are different. In this way, the first main transmission gearshift mechanism 123 can select to transmit power to the third main transmission gear 122a or the fourth main transmission gear 122b through one of the output sides by gearshift.

[0079] The second main speed change gear mechanism 124 is used to selectively transmit the power of the first transmission shaft 121 to the second transmission shaft 122. Among them, the second main speed change gear mechanism 124 has two input sides, and the two input sides are respectively in meshing transmission with the corresponding first main transmission gear 121a and second main transmission gear 121b, and the meshing transmission ratios are different. In this way, the second main speed change gear mechanism 124 can select to transmit power to the first main transmission gear 121a or the second main transmission gear 121b through one of the input sides by gear position switching.

[0080] Thus, through the cooperation of the first main speed change gear mechanism 123 and the second main speed change gear mechanism 124, there are four different speed transmission modes for the power of the first transmission shaft 121 to be transmitted to the second transmission shaft 122.

[0081] Specifically, the first main speed change gear mechanism 123 includes a first main gear position gear 1230, a first main speed change synchronizer 1231, and a second main gear position gear 1232 arranged in sequence along the axial direction of the first transmission shaft 121. The first main gear position gear 1230 and the second main gear position gear 1232 are rotatably arranged on the first transmission shaft 121 and are respectively arranged on the two output sides of the first main speed change gear mechanism 123. The first main gear position gear 1230 is meshed with the third main transmission gear 122a, and the second main gear position gear 1232 is meshed with the fourth main transmission gear 122b. Among them, a fifth main transmission gear 121c meshed with the first main speed change synchronizer 1231 is provided on the first transmission shaft 121. The first main speed change synchronizer 1231 is used to perform gear position switching so that the fifth main transmission gear 121c is selectively in transmission connection with the first main gear position gear 1230 or the second main gear position gear 1232, so as to transmit the power of the first transmission shaft 121 to the second transmission shaft 122.

[0082] The second main speed change gear mechanism 124 includes a third main gear position gear 1240, a second main speed change synchronizer 1241, and a fourth main gear position gear 1242 arranged in sequence along the axial direction of the second transmission shaft 122. The third main gear position gear 1240 and the fourth main gear position gear 1242 are rotatably arranged on the second transmission shaft 122 and are respectively arranged on the two input sides of the second main speed change gear mechanism 124. The third main gear position gear 1240 is meshed with the first main transmission gear 121a, and the fourth main gear position gear 1242 is meshed with the second main transmission gear 121b. A sixth main transmission gear 122c meshed with the second main speed change synchronizer 1241 is provided on the second transmission shaft 122. The second main speed change synchronizer 1241 is used to perform gear position switching so that the sixth main transmission gear 122c is selectively in transmission connection with the third main gear position gear 1240 and the fourth main gear position gear 1242, so as to transmit the power of the first transmission shaft 121 to the second transmission shaft 122.

[0083] Please refer to Figure 4, the above-mentioned auxiliary speed change gear module 130 includes a third transmission shaft 131, a fourth transmission shaft 132, a first auxiliary speed change gear mechanism 133, and a second auxiliary speed change gear mechanism 134. The third transmission shaft 131 and the fourth transmission shaft 132 are arranged in parallel. The third transmission shaft 131 is coaxially inserted into the shaft hole of the second transmission shaft 122 and is rotationally matched with the second transmission shaft 122 through a bearing. The fourth transmission shaft 132 is coaxially sleeved on the first transmission shaft 121 and is rotationally matched with the first transmission shaft 121 through a bearing. In this way, the coaxiality of the third transmission shaft 131 and the second transmission shaft 122, and the fourth transmission shaft 132 and the first transmission shaft 121 after installation can be ensured.

[0084] The first auxiliary speed change gear mechanism 133 and the second auxiliary speed change gear mechanism are arranged in sequence along the axial direction of the third transmission shaft 131. One end of the third transmission shaft 131 away from the first auxiliary speed change gear mechanism 133 is in transmission connection with the input end of the creep gear module 140. The fourth transmission shaft 132 is provided with a first auxiliary transmission gear 132a, a second auxiliary transmission gear 132b, a third auxiliary transmission gear 132c, and a fourth auxiliary transmission gear 132d arranged in sequence along its axial direction. The first auxiliary transmission gear 132a, the second auxiliary transmission gear 132b, the third auxiliary transmission gear 132c, and the fourth auxiliary transmission gear 132d can rotate synchronously with the fourth transmission shaft 132.

[0085] The first auxiliary speed change gear mechanism 133 is used to selectively transmit the power output by the main speed change gear module 120 to the third transmission shaft 131. One input side of the first auxiliary speed change gear mechanism 133 is in transmission connection with the output end of the main speed change gear module 120 (specifically, the second transmission shaft 122 at the output end) and is in meshing transmission with the first auxiliary transmission gear 132a. The other input side of the first auxiliary speed change gear mechanism 133 is in meshing transmission with the second auxiliary transmission gear 132b. Among them, the transmission ratios of the first auxiliary speed change gear mechanism 133 meshing with the first auxiliary transmission gear 132a and the second auxiliary transmission gear 132b are different. In this way, the first auxiliary speed change gear mechanism 133 can, through gear shift, select to directly transmit the power to the third transmission shaft 131 through one input side in transmission connection with the second transmission shaft 122, or indirectly transmit the power to the third transmission shaft 131 through the first auxiliary transmission gear 132a, the fourth transmission shaft 132, and the second auxiliary transmission gear 132b through the other input side.

[0086] The second auxiliary transmission gear mechanism 134 is used to selectively transmit the power output by the main transmission gear module 120 to the third transmission shaft 131. The second auxiliary transmission gear mechanism 134 also has two input sides. One input side of the second auxiliary transmission gear mechanism 134 is meshed and driven with the third auxiliary transmission gear 132c, and the other input side of the second auxiliary transmission gear mechanism 134 is meshed and driven with the fourth auxiliary transmission gear 132d. Among them, the transmission ratios of the second auxiliary transmission gear mechanism 134 meshed with the third auxiliary transmission gear 132c and the fourth auxiliary transmission gear 132d are different.

[0087] It can be understood that since the first auxiliary transmission gear 132a is indirectly in transmission connection with the output end of the main transmission gear module 120, the fourth transmission shaft 132 is always in a rotating state when there is power output at the output end of the main transmission gear module 120. Thus, the second auxiliary transmission gear mechanism 134 can select to transmit the power of the fourth transmission shaft 132 to the third transmission shaft 131 through the third auxiliary transmission gear 132c or the fourth auxiliary transmission gear 132d by shifting gears.

[0088] Therefore, through the cooperation of the first auxiliary transmission gear mechanism 133 and the second auxiliary transmission gear mechanism 134, there are four different speed transmission methods for the power of the first transmission shaft 121 to be transmitted to the third transmission shaft 131.

[0089] Specifically, the first auxiliary transmission gear mechanism 133 includes a first auxiliary gear 1330, a first auxiliary transmission synchronizer 1331, and a second auxiliary gear 1332 arranged in sequence along the axial direction of the third transmission shaft 131. The first auxiliary gear 1330 and the second auxiliary gear 1332 are rotatably arranged on the third transmission shaft 131 and are respectively arranged on the two input sides of the first auxiliary transmission gear mechanism 133. The first auxiliary gear 1330 is in transmission connection with the second transmission shaft 122 of the main transmission gear module 120 and is meshed with the first auxiliary transmission gear 132a, and the second auxiliary gear 1332 is meshed with the second auxiliary transmission gear 132b.

[0090] Optionally, the specific first auxiliary gear 1330 and the second transmission shaft 122 of the main transmission gear module 120 are in transmission connection by means of detachable connection methods such as key connection, flange connection, or coupling connection.

[0091] Furthermore, a fifth auxiliary transmission gear 131a meshed with the first auxiliary transmission synchronizer 1331 is provided on the third transmission shaft 131. The first auxiliary transmission synchronizer 1331 is used to perform gear shifting so that the fifth auxiliary transmission gear 131a is selectively in transmission connection with the first auxiliary gear 1330 or the second auxiliary gear 1332, thus transmitting the power output by the second transmission shaft 122 to the third transmission shaft 131.

[0092] The second sub-speed gear mechanism 134 includes a third sub-speed gear 1340, a second sub-speed synchronizer 1341 and a fourth sub-speed gear 1342 which are arranged in sequence along the axial direction of the third transmission shaft 131. The third sub-speed gear 1340 and the fourth sub-speed gear 1342 are rotatably provided on the third transmission shaft 131 and are respectively arranged on the two input sides of the second sub-speed gear mechanism 134. The third sub-speed gear 1340 is engaged with the third sub-transmission gear 132c, and the fourth sub-speed gear 1342 is engaged with the fourth sub-transmission gear 132d.

[0093] Among them, the third transmission shaft 131 is also provided with a sixth sub-transmission gear 131b that meshes with the second sub-transmission synchronizer 1341. The second sub-transmission synchronizer 1341 is used to perform gear switching so that the sixth sub-transmission gear 131b is selectively connected to the third sub-transmission gear 132c or the fourth sub-transmission gear 132d. In this way, the power output by the second transmission shaft 122 is transmitted to the third transmission shaft 131 after passing through the fourth transmission shaft 132.

[0094] See also Figure 1 and Figure 2 The crawler gear module 140 further includes a first output shaft 141, a crawler gear mechanism 142, and a second transition transmission mechanism 143. The crawler gear mechanism 142 includes a first crawler gear 1420, a crawler synchronizer 1421, and a second crawler gear 1422, arranged in sequence along the axial direction of the first output shaft 141. Both the first crawler gear 1420 and the second crawler gear 1422 are rotatably mounted on the first output shaft 141. The first crawler gear 1420 is in driving connection with the output end of the auxiliary transmission module 130, specifically, with the third transmission shaft 131 located at the output end of the auxiliary transmission module 130.

[0095] Furthermore, the first output shaft 141 and the third transmission shaft 131 are coaxially arranged. One end of the first output shaft 141 is rotatably inserted into the shaft hole of the third transmission shaft 131 and a bearing is provided between the first output shaft 141 and the third transmission shaft 131 to ensure coaxiality after installation.

[0096] Optionally, the first crawler gear 1420 and the third transmission shaft 131 are connected in a transmission manner using a detachable connection method such as a key connection, a flange connection or a coupling connection.

[0097] The second intermediate transmission mechanism 143 is rotatably arranged in the creep gear module 140 and meshes with and drives the first creep gear 1420 and the second creep gear 1422 respectively. Among them, a creep drive gear 141a meshing with the creep synchronizer 1421 is arranged on the first output shaft 141, and the creep synchronizer 1421 is used to perform gear shifting so that the creep drive gear 141a is selectively connected to the first creep gear 1420 or the second creep gear 1422 for transmission connection.

[0098] In this embodiment, the second intermediate transmission mechanism 143 can also be implemented by two independent gears. In some embodiments, the second intermediate transmission mechanism 143 can be selected as a double gear structure. The structure of the double gear structure can be specifically referred to the structure description of the first intermediate transmission mechanism 113 above, and will not be elaborated here. This embodiment takes the example that the second intermediate transmission mechanism 143 can also be implemented by two independent gears for illustration.

[0099] Specifically, the second intermediate transmission mechanism 143 includes a first creep drive gear 1430, a second creep drive gear 1431 and a creep drive shaft 1432. The creep drive shaft 1432 is rotatably arranged on the housing of the creep gear module 140, and one end of the creep drive shaft 1432 is sleeved on the fourth drive shaft 132 and is rotationally matched with the fourth drive shaft 132 through a bearing to ensure the coaxiality after installation.

[0100] The first creep drive gear 1430 and the second creep drive gear 1431 are installed on the creep drive shaft 1432 and can rotate synchronously with the creep drive shaft 1432. The first creep drive gear 1430 meshes with the first creep gear 1420, and the second creep drive gear 1431 meshes with the second creep gear 1422. The creep synchronizer 1421 is used to perform gear shifting so that the power output by the third drive shaft 131 is directly transmitted to the first output shaft 141, or is transmitted to the first output shaft 141 through the first creep drive gear 1430, the creep drive shaft 1432 and the second creep drive gear 1431.

[0101] In this way, through the cooperation of the creep synchronizer 1421 in the creep gear module 140, there are two different speed transmission methods for the power of the third drive shaft 131 to be transmitted to the first output shaft 141.

[0102] Please refer to Figure 1 、 Figure 2 and Figure 5, in this embodiment, the first input shaft 111, the first transmission shaft 121, the fourth transmission shaft 132, and the crawler transmission shaft 1432 are coaxially arranged in a straight line in sequence and are all hollow shafts. Among them, the second input shaft 410 in the power output module 400 sequentially passes through the first input shaft 111, the first transmission shaft 121, the fourth transmission shaft 132, and the crawler transmission shaft 1432 and then is in transmission connection with the power supply module 200 (the second input shaft 410 also passes through the first clutch 300).

[0103] Please refer to Figure 6 , further, the power output transmission module 420 includes a second clutch 421 and a gear transmission module 422. Both the second clutch 421 and the gear transmission module 422 can be integrated into the housing of the power output transmission module 420. The second clutch 421 has an input end and an output end. Among them, the input end of the second clutch 421 is in transmission connection with the second input shaft 410, and the output end of the second clutch 421 is provided with a fifth transmission shaft 4210 integrally constructed with the second clutch 421.

[0104] Optionally, the second input shaft 410 and the input end of the second clutch 421 are connected by key fit, coupling fit, or flange fit.

[0105] Optionally, the second clutch 421 can be selected as a wet clutch, which helps with heat dissipation and can withstand a greater torque to meet the working requirements of the working machine.

[0106] The gear transmission module 422 is in transmission connection with the fifth transmission shaft 4210. The gear transmission module 422 includes a power output gear position mechanism 4220 and a second output shaft 4224. The power output gear position mechanism 4220 transmits the power of the fifth transmission shaft 4210 to the second output shaft 4224 by performing gear shifting. The second output shaft 4224 extends outside the housing of the power output module 400.

[0107] Further, along the axial direction of itself, the fifth transmission shaft 4210 is also sequentially provided with a first power transmission gear 4211 and a second power transmission gear 4212, and both the first power transmission gear 4211 and the second power transmission gear 4212 can rotate with the fifth transmission shaft 4210.

[0108] The power output gear position mechanism 4220 is arranged on the second output shaft 4224 and meshes with the first power transmission gear 4211 and the second power transmission gear 4212 respectively. The power output gear position mechanism 4220 is used to perform gear shifting so that the fifth transmission shaft 4210 can choose to transmit power to the second output shaft 4224 through the first power transmission gear 4211 or through the second power transmission gear 4212.

[0109] The meshing transmission ratio between the power take-off gear mechanism 4220 and the first power transmission gear 4211 is greater than the meshing transmission ratio between the power take-off gear mechanism 4220 and the second power transmission gear 4212; or, the meshing transmission ratio between the power take-off gear mechanism 4220 and the first power transmission gear 4211 is less than the meshing transmission ratio between the power take-off gear mechanism 4220 and the second power transmission gear 4212.

[0110] Specifically, the power take-off gear mechanism 4220 includes a first output gear 4221, a power take-off synchronizer 4222, and a second output gear 4223 arranged in sequence along the axial direction of the second output shaft 4224. The first output gear 4221 and the second output gear 4223 are rotatably arranged on the second output shaft 4224. The first output gear 4221 meshes with the first power transmission gear 4211, and the second output gear 4223 meshes with the second power transmission gear 4212.

[0111] Wherein, a third power transmission gear 4225 meshing with the power take-off synchronizer 4222 is further provided on the second output shaft 4224. The power take-off synchronizer 4222 is used to perform gear shifting so that the third power transmission gear 4225 is selectively connected to the first output gear 4221 or the second output gear 4223 for transmission, and the power of the fifth transmission shaft 4210 is output through the second output shaft 4224.

[0112] It should be noted that the shuttle synchronizer 1121, the first main transmission synchronizer 1231, the second main transmission synchronizer 1241, the first auxiliary transmission synchronizer 1331, the second auxiliary transmission synchronizer 1341, the creep synchronizer 1421, and the power take-off synchronizer 4222 mentioned above can adopt a manual mechanical shifting structure to cope with the complex operating environment of the work machine and improve reliability.

[0113] Of course, in some embodiments, an electronically controlled automatic shifting method can be adopted: an electronically controlled hydraulic actuator + TCU is used to control shifting to achieve automatic gear shifting.

[0114] In other embodiments, a hybrid power shifting method can be adopted: an electric motor is integrated into the gearbox, and the motor is used to assist in shifting, and a battery and an electronic control system are provided accordingly.

[0115] Please refer to Figures 1 to 6 , furthermore, this embodiment also provides a work machine, especially a work machine in the agricultural field.
