Description

Technical Field

[0001] The invention belongs to the technical field of gearboxes, and in particular relates to a multi-speed multifunctional gearbox. Background Art

[0002] The existing gearbox is most suitable for small-area farmland operations and transportation in three zones, ditches, and poor road conditions; the current tractor is a universal gearbox, which is also universal, and its function is relatively simple, and it can only provide power to the vehicle. Therefore, the performance and reliability of use when used in the above working conditions cannot meet the user's requirements. If you want to achieve its purpose, you must increase the power, add a sub-gearbox or a front and rear drive transfer case. If you simply superimpose the existing various devices, it will not only make it bulky, the cost of transformation is very high, but also make the product performance fail to meet the requirements of stability and reliability. Moreover, the practicality of a single-input gearbox is greatly reduced, and it is difficult to meet the purpose of users to adapt to different power input devices independently, resulting in low adaptability and practicality. Summary of the invention

[0007] A second transmission shaft is provided in the chassis, the second transmission shaft is located above the first transmission shaft, and its horizontal plane projection is located at the midline of the first transmission shaft and the first input shaft, two adjusting gears are slidably connected to the second transmission shaft, namely the first adjusting gear and the second adjusting gear, and a third adjusting gear is provided between the first adjusting gear and the second adjusting gear; the first adjusting gear can slide to different positions on the second transmission shaft and mesh with the first input gear and the second transmission gear respectively; the second adjusting gear can slide to different positions on the second transmission shaft and mesh with the third transmission gear and the first output gear respectively;

[0008] The chassis is also provided with a gear shaft, on which a plurality of gear gears of different diameters are arranged at intervals; the gear shaft is provided with a fifth transmission gear, which is meshed with the third adjustment gear;

[0009] A second input shaft is also provided in the chassis, and a plurality of gear-changing gear sets for meshing with gears of different gear positions are slidably connected to the second input shaft, and the second input shaft is externally connected to a power device.

[0010] Furthermore, the first input shaft, the first input shaft, the second transmission shaft, the gear shaft, and the second input shaft are all spline shafts.

[0011] Furthermore, the gears on the first input shaft, the first input shaft, the second transmission shaft, the gear shaft, and the second input shaft are all provided with spline grooves that cooperate with the spline shaft.

[0012] Furthermore, the shift gear set includes a plurality of shift gears with different diameters and arranged at intervals, and the shift gears can slide on the second output shaft.

[0013] Furthermore, the input end of the first input shaft, the output end of the first output shaft, the input end of the second input shaft, and the output end of the second input shaft may all be provided with brakes.

[0014] Furthermore, the input end of the first output shaft and the input end of the second input shaft can be configured with a clutch as required.

[0015] Further, the width of the first input gear is greater than the sum of the widths of the first transmission gear and the first adjusting gear, and the width of the first output gear is greater than the sum of the widths of the second adjusting gear and the fourth transmission gear.

[0016] The effects of the working principle of the present invention are as follows:

[0017] In this scheme, a first input shaft and a first output shaft are arranged in the chassis, and the first input shaft and the first output shaft are arranged side by side on both sides of the inner wall of the chassis;

[0018] When the first input shaft is used as the power input end:

[0019] For example, the first input shaft can be connected to the rotating shaft of the car, and the rotation of the rotating shaft of the car can drive the first input shaft to rotate, and the rotation of the first input shaft can drive the first transmission gear on the first transmission shaft to rotate, and at the same time, the second transmission gear located on the same bearing will also rotate;

[0020] When the first adjusting gear on the second transmission shaft is meshed with the first input gear, the second transmission shaft moves in the opposite direction to the first input shaft. At this time, the second adjusting gear can be meshed with the third transmission gear or the first output gear as needed. When the second adjusting gear is meshed with the third transmission gear, the third transmission gear rotates forward, and the fourth transmission gear on the same bearing rotates in the same direction. The fourth transmission gear is meshed with the first output gear, causing the first output gear to rotate in the opposite direction; when the second adjusting gear is meshed with the first output gear, the first output gear rotates forward.

[0021] When the first adjusting gear is meshed with the second transmission gear, the second transmission shaft moves in the same direction as the first input shaft; at this time, the second adjusting gear can be meshed with the third transmission gear or the first output gear as needed. When the second adjusting gear is meshed with the third transmission gear, the third transmission gear rotates in the opposite direction, and the fourth transmission gear located on the same bearing rotates in the same direction. The fourth transmission gear is meshed with the first output gear, so that the first output gear rotates in the forward direction; when the second adjusting gear is meshed with the first output gear, the first output gear rotates in the opposite direction.

[0022] From the above, it can be seen that by changing the meshing relationship between the first adjusting gear and the second transmission gear or the first input gear, the first output shaft can achieve different changes in the forward and reverse directions; similarly, by changing the meshing relationship between the second adjusting gear and the third transmission gear or the first output gear, the first output shaft can also achieve different changes in the forward and reverse directions; at this time, the first output shaft can be used as one of the power output ends.

[0023] At the same time, a gear shaft is also provided in the chassis, and a plurality of gear gears with different diameters are arranged at intervals on the gear shaft; a fifth transmission gear is provided on the gear shaft, and the fifth transmission gear is meshed with the third adjustment gear;

[0024] The rotation of the third adjusting gear drives the fifth transmission gear to rotate, which can drive the gear shaft to rotate. A second input shaft is also provided in the chassis. A plurality of shifting gear sets for meshing different gear gears are slidably connected to the second input shaft. The shifting gear sets include a plurality of shifting gears with different diameters and arranged at intervals. The shifting gears can slide on the second output shaft, thereby adjusting the meshing of different shifting gears with corresponding gear gears to make the second input shaft rotate. At this time, the output end of the second input shaft can be used as another power output end, and the effect of shifting and changing gears can also be achieved.

[0025] When the second input shaft is used as the power input end:

[0026] The input end of the second input shaft is externally connected to a power device, and the power device drives the second input shaft to rotate, and adjusts different gear-adjusting gears to mesh with the gear gears to realize speed shifting. At the same time, the gear shaft is driven, and the fifth transmission gear on the gear shaft meshes with the third adjusting gear, so that the second transmission shaft is driven. At this time, the meshing relationship between the first adjusting gear and the second transmission gear and the first input gear can be adjusted arbitrarily according to needs to realize the forward or reverse rotation of the first input shaft. Similarly, the meshing relationship between the second adjusting gear and the third transmission gear and the first output gear can be adjusted according to needs to realize the forward or reverse rotation of the first output shaft; at this time, the first input shaft and the second output shaft can be used as two power output ends under this working condition, and can realize different output conditions of simultaneous forward rotation, simultaneous reverse rotation, or one forward rotation and the other reverse rotation;

[0027] In summary, the multifunctional multi-speed gearbox of the present invention has various functions, is reversible, has multiple outputs, and can be variable-speed adjusted. Its practicality is greatly enhanced, and it can meet the purpose of users' independent adaptation to different power input devices. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] For example, the first input shaft 2 can be connected to the shaft of the car, and the rotation of the shaft of the car can drive the first input shaft 2 to rotate, and the rotation of the first input shaft 2 can drive the first transmission gear 8 on the first transmission shaft 22 to rotate, and at the same time, the second transmission gear 9 located on the same bearing will also rotate;

[0051] When the first adjusting gear 14 on the second transmission shaft 13 is meshed with the first input gear 3, the second transmission shaft 13 moves in the opposite direction to the first input shaft 2. At this time, the second adjusting gear 15 can be meshed with the third transmission gear 10 or the first output gear 5 as needed.
