Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of 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.

[0022] like Figure 1 As shown in the figure, the loader two-in-one transmission provided in this embodiment includes: a power input shaft 2, a drive output shaft 8, and a superstructure output shaft 26; the power input shaft 2, drive output shaft 8, and superstructure output shaft 26 are integrated and installed in the same gearbox to form a compact and functionally integrated transmission system. The drive output shaft 8 and the superstructure output shaft 26 are respectively connected to the power input shaft 2 in a switchable transmission manner.

[0023] Among them, the drive output shaft 8 and the upper output shaft 26 can transmit power to the power input shaft 2 through gear transmission or other means. In the power transmission route, the power on / off state can also be adjusted by devices such as clutches and gear shifters.

[0024] In an optional embodiment, the power input shaft 2 is used to receive power input from the loader's engine or motor. A first clutch assembly can be provided between the power input shaft 2 and the drive output shaft 8. By controlling the engagement and disengagement of the first clutch assembly, the on / off transmission connection between the power input shaft 2 and the drive output shaft 8 can be achieved. The drive output shaft 8 is used to transmit power to the loader's driving system, such as the gearbox output shaft connecting to the drive axle, thereby driving the wheels to rotate.

[0025] In an optional embodiment, a second clutch assembly can be provided between the power input shaft 2 and the upper structure output shaft 26. By controlling the engagement and disengagement of the second clutch assembly, the on / off transmission connection between the power input shaft 2 and the upper structure output shaft 26 can be realized. The upper structure output shaft 26 is used to transmit power to the upper structure working device, such as the hydraulic pump of the loader, the working device drive mechanism, etc., to realize the loading, lifting, tipping and other operating functions.

[0026] Furthermore, the first clutch assembly and the second clutch assembly can adopt common structures such as electromagnetic clutches, hydraulic clutches or multi-plate friction clutches, and their control methods can be manual control, electric control or hydraulic control, and the selection and configuration can be based on actual usage requirements.

[0027] In an optional embodiment, a reduction gear set is provided between the drive output shaft 8 and the power input shaft 2 to achieve speed reduction and torque increase during power transmission, thereby meeting the traction requirements of the loader during operation. Similarly, an independent transmission gear set can also be provided between the superstructure output shaft 26 and the power input shaft 2 to achieve power matching for the superstructure working device.

[0028] The loader can selectively engage either the drive output shaft 8 or the superstructure output shaft 26, or engage both simultaneously, depending on the operating condition. For example, in driving mode, only the first clutch assembly is engaged, and power drives the wheels via the drive output shaft 8; in working mode, the second clutch assembly is engaged, and power drives the working device via the superstructure output shaft 26; in combined operating conditions, both clutch assemblies are engaged simultaneously, enabling simultaneous driving and working. This integrated control of drive and superstructure power output improves the loader's operating efficiency and flexibility, and offers advantages such as compact structure, easy operation, and rapid response, making it suitable for various types of loading machinery.

[0029] In this embodiment of the utility model, the power input shaft 2 is coaxial with the upper output shaft 26, and an upper shift sleeve 27 is movably installed between the power input shaft 2 and the upper output shaft 26; one end of the upper shift sleeve 27 is engaged with the upper output shaft 26 for transmission, and the other end of the upper shift sleeve 27 is connected to the power input shaft 2 for on / off transmission.

[0030] Specifically, one end of the upper gear shift sleeve 27 is provided with a meshing structure (such as a spline or gear teeth) that matches the upper gear output shaft 26, thus forming a fixed transmission connection with the upper gear output shaft 26. When the shift sleeve moves axially to this end position, power can be transmitted from the upper gear shift sleeve 27 to the upper gear output shaft 26, realizing power output. The other end of the upper gear shift sleeve 27 is provided with a disengageable transmission connection structure between it and the power input shaft 2. For example, this end is also provided with a spline structure or a clutch tooth structure, which cooperates with the corresponding structure on the power input shaft 2. When the upper gear shift sleeve 27 slides to this end position, it engages with the power input shaft 2, realizing power transmission between the power input shaft 2 and the upper gear shift sleeve 27; when the sleeve disengages from this end position, the transmission between the power input shaft 2 and the upper gear shift sleeve 27 is disconnected, and power transmission is interrupted. By controlling the axial position change of the upper gear shift sleeve 27, different working modes can be switched. For example, in the first position, the upper body shift sleeve 27 is engaged with the power input shaft 2 but disengaged from the upper body output shaft 26, at which point power cannot be output to the upper body component; in the second position, the upper body shift sleeve 27 is engaged with both the power input shaft 2 and the upper body output shaft 26, thus achieving power transmission; in the third position, the upper body shift sleeve 27 is engaged only with the upper body output shaft 26 and disengaged from the power input shaft 2, thereby achieving power locking or neutral state.

[0031] Furthermore, the axial movement of the upper gear shift sleeve 27 is driven by a shift actuator, such as a hydraulic cylinder, an electromagnetic drive device, or a manual shift mechanism. The shift actuator is connected to the control system and can automatically or manually control the position of the shift sleeve according to operating conditions, achieving flexible control of the power transmission path. Synchronization devices (such as synchronizing rings or synchronizing gear blocks) can be installed between the power input shaft 2 and the upper gear shift sleeve 27, and between the upper gear shift sleeve 27 and the upper gear output shaft 26, to reduce impact during shifting and improve shifting smoothness and reliability.

[0032] Furthermore, a first needle roller bearing 22 is installed between the power input shaft 2 and the upper gear shift sleeve 27. One end of the upper gear shift sleeve 27 is inserted into the power input shaft 2, and the other end is inserted into the upper gear output shaft 26, thereby ensuring that the power input shaft 2, the upper gear shift sleeve 27, and the upper gear output shaft 26 are coaxial. The first needle roller bearing 22 provides lubrication between the power input shaft 2 and the upper gear shift sleeve 27, reducing the resistance experienced by the power input shaft 2 when power transmission between the upper gear shift sleeve 27 and the power input shaft 2 is disconnected.

[0033] Furthermore, the loader's two-in-one transmission also includes multiple upper structure output shaft gears 19; these gears are spaced apart around the upper structure output shaft 26, and each gear meshes with the upper structure output shaft 26. Each gear is connected to a corresponding upper structure power output interface; for example, the hydraulic pump upper structure output shaft gear 19 and the upper structure output shaft 26 use a helical gear meshing structure to improve transmission smoothness and load-bearing capacity. In optional embodiments, spur gears, bevel gears, or other meshing forms can be used according to actual application requirements, as long as effective power transmission between the upper structure output shaft 26 and the multiple upper structure output shaft gears 19 can be achieved. The drive shaft is used to transmit the power output from the transmission to the loader's upper structure working device. This structural design facilitates a "one shaft, multiple outputs" power distribution mode, meeting the needs of multi-device collaborative operation under different working conditions.

[0034] Furthermore, the power input shaft 2 and the drive output shaft 8 are connected via an intermediate shaft 4; the drive output shaft 8 is equipped with an output shaft first stop tooth 11, a drive shift sleeve 12, and an output shaft second stop tooth 13; the output shaft first stop tooth 11 and the output shaft second stop tooth 13 are respectively lubricated and rotatably sleeved on the drive output shaft 8 through a second needle roller bearing 14, and the output shaft first stop tooth 11 and the output shaft second stop tooth 13 are respectively connected to the intermediate shaft 4; the drive shift sleeve 12 is provided with teeth that are adapted to engage with the output shaft first stop tooth 11 and the output shaft second stop tooth 13, the drive shift sleeve 12 is located between the output shaft first stop tooth 11 and the output shaft second stop tooth 13, and slides axially on the drive output shaft 8, and the drive shift sleeve 12 is circumferentially limited relative to the drive output shaft 8. The drive shift sleeve 12 has engagement teeth (i.e., shift teeth) at both ends that are adapted to the first gear 11 and the second gear 13 of the output shaft, respectively. When the drive shift sleeve 12 slides axially to one end, its engagement teeth mesh with the teeth of the corresponding gear (first gear or second gear), thereby locking the gear onto the drive output shaft 8 and making it rotate synchronously with the drive output shaft 8 to achieve power output. When the drive shift sleeve 12 slides to the side close to the first gear 11 of the output shaft, its engagement teeth mesh with the engagement teeth of the first gear 11 of the output shaft, making the first gear 11 of the output shaft rotate synchronously with the drive output shaft 8, and power is transmitted through this first gear. When the drive shift sleeve 12 slides to the side close to the second gear 13 of the output shaft, its engagement teeth mesh with the second gear 13 of the output shaft, making the second gear 13 of the output shaft rotate synchronously with the drive output shaft 8, and power is transmitted through this second gear, thereby achieving power output in two different gear positions.

[0035] Output shaft first gear 11 and output shaft second gear 13 are respectively connected to corresponding gears on intermediate shaft 4 via gear meshing. That is, after power is input from power input shaft 2, it is transmitted to output shaft first gear 11 or output shaft second gear 13 via intermediate shaft 4. Finally, through the switching action of drive shift sleeve 12, the power output of drive output shaft 8 in different gears is realized. During the shifting process, the axial movement of drive shift sleeve 12 can be realized by operating mechanism (such as manual shift lever, hydraulic cylinder, motor drive, etc.), and the specific structure can be designed according to actual application requirements.

[0036] See Figure 1 An input shaft bearing 1 is fitted onto the end of the power input shaft 2 opposite to the upper gear shift sleeve 27, and an upper gear output shaft bearing 23 is fitted onto the output shaft 26. The upper gear output shaft bearing 23 is fixed to the output shaft 26 by an output shaft bearing limiting spacer 24 and an output shaft bearing limiting retainer 25. In addition, an output shaft front bearing 20 is fitted onto one end of each upper gear output shaft gear 19, and an output shaft rear bearing 21 is fitted onto the other end, thereby ensuring that all upper gear output shaft gears 19 can rotate smoothly and steadily.

[0037] In addition, intermediate shaft bearings 3 are installed at both ends of the intermediate shaft 4, and the intermediate shaft bearings 3 are axially limited by the intermediate shaft bearing limiting rings 18 installed on the intermediate shaft 4.

[0038] Furthermore, the intermediate shaft 4 has an intermediate shaft first stop tooth that meshes with the output shaft first stop tooth 11, and the intermediate shaft first stop tooth is integrally formed with the intermediate shaft 4; the intermediate shaft 4 is equipped with an intermediate shaft second stop tooth 16, and the intermediate shaft second stop tooth 16 is circumferentially limited to the intermediate shaft 4 by a key 17; the power input shaft 2, the intermediate shaft second stop tooth 16 and the output shaft second stop tooth 13 are sequentially connected for transmission.

[0039] Specifically, an intermediate shaft first stop tooth 11 is integrally formed on the intermediate shaft 4. This intermediate shaft first stop tooth 11 is in constant mesh with the corresponding first stop tooth on the output shaft, forming the first gear power transmission path. Since the intermediate shaft first stop tooth 11 and the intermediate shaft 4 are an integral structure, no additional assembly or fixing structure is required, thereby improving the coaxiality accuracy between the gear and the shaft and enhancing the stability and load-bearing capacity of the transmission. The intermediate shaft second stop tooth 16 is a detachable structure, and is circumferentially limited by key 17 to the intermediate shaft 4, ensuring that no relative rotation occurs during power transmission. The design of key 17 allows for certain assembly adjustments of the intermediate shaft second stop tooth 16 in the axial direction to meet the fine-tuning requirements of the transmission center distance for different models, improving the adaptability and versatility of this transmission structure.

[0040] Furthermore, one end of the drive output shaft 8 is connected to the first flange 5 and the other end is connected to the second flange 15. One of the first flange 5 and the second flange 15 is used to connect to the front wheel drive of the loader and the other is used to connect to the rear wheel drive of the loader, thereby enabling the loader to achieve full-time four-wheel drive.

[0041] In addition, the first flange 5 and the second flange 15 are respectively connected to the drive output shaft 8 through spline connection, thus having a strong torque carrying capacity.

[0042] Flange locking nuts 7 are connected to both ends of the drive output shaft 8. The two flange locking nuts 7 press inward against the first flange 5 and the second flange 15, respectively, to ensure that the first flange 5 and the second flange 15 are axially fixed relative to the drive output shaft 8. In addition, multiple flange connecting bolts 6 are installed at circumferential intervals on the first flange 5 and the second flange 15, and the downstream drive shaft is connected and fixed by the flange connecting bolts 6.

[0043] In addition, the drive output shaft 8 is rotatably coupled in the gearbox via two drive output shaft bearings 9. One drive output shaft bearing 9 is adjacent to the first gear 11 of the output shaft, and a bearing spacer 10 is provided between the two. The other drive output shaft bearing 9 is adjacent to the second gear 13 of the output shaft, and a bearing spacer 10 is also provided between the two.

[0044] The loader provided in this embodiment is equipped with the loader two-in-one transmission described in the above embodiments. It has the technical advantages of a loader two-in-one transmission, which can reduce the overall layout space requirements of the loader and help reduce the manufacturing cost of the loader.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
