Description

Technical Field

[0001] This utility model relates to the field of gear shifting and transmission output, and in particular to a direct-drive traction micro-tiller gearbox. Background Technology

[0002] The existing traction gearboxes have an unreasonable structural design. When dealing with different operating environments, they often adopt the design solution of adding an auxiliary gearbox, which increases costs and makes replacement inconvenient.

[0003] Therefore, we propose a direct-drive traction gearbox. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a direct-drive traction gearbox. The device adopts an integrated design and adds a rear output design, which enables it to be modified into a four-wheel drive. It has the characteristics of simple structure, convenient operation, low failure rate, convenient maintenance and upkeep, and long service life. When there is a need to replace the gearbox, it improves the replacement speed and ensures mechanical precision.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A direct-drive traction gearbox includes a direct-drive traction gearbox body. A shift shaft is internally connected to the direct-drive traction gearbox body, and a shift fork is externally fixedly connected to the shift shaft. A shaft one is internally rotatably connected to the direct-drive traction gearbox body, and a gear one is externally fixedly connected to the shaft one. A shaft two is internally rotatably connected to the direct-drive traction gearbox body, and a gear two and a gear three are externally engaged. The shift fork is rotatably connected between gear two and gear three. A gear four is externally fixedly connected to the shaft two and meshes with gear one. A shaft three is internally rotatably connected to the direct-drive traction gearbox body, and a gear five and a gear six are externally fixedly connected to the shaft three. A shaft four is internally rotatably connected to the direct-drive traction gearbox body, and a gear seven and a gear eight are externally fixedly connected to the shaft four.

[0007] Shaft 1 connects to the engine output end, driving gear 1 to rotate. Gear 1 then drives gear 4, which in turn drives shaft 2 to rotate. Shaft 2 drives the double gears, namely gears 2 and 3, to rotate synchronously. Shifting the gear shift shaft causes gears 2 and 3 to slide along shaft 2, allowing gears 2 and 3 to engage with gears 6, 7, and 8 respectively. When gear 3 engages with gear 6, it drives shaft 3 to rotate. When gear 2 engages with gear 7, or gear 3 engages with gear 8, it drives shaft 4 to rotate, thus forming three gears. This allows the equipment to select the most suitable gear according to different load and speed requirements, improving operating efficiency and adaptability.

[0008] Furthermore, gear two and gear three are fixedly connected, and gear two and gear three constitute a double gear.

[0009] Furthermore, the shift shaft extends to the outside of the direct-connect traction gearbox body, and the shaft four extends to the outside of the direct-connect traction gearbox body.

[0010] Furthermore, gears two and three mesh with gears six, seven and eight respectively by shifting the gear shaft, and gear five meshes with gear seven.

[0011] Furthermore, a first bevel gear is fixedly connected to the outside of the fourth shaft, and a fifth shaft is rotatably connected inside the direct-drive traction gearbox body, the fifth shaft passing through the direct-drive traction gearbox body.

[0012] Furthermore, a second bevel gear is fixedly connected to the outside of the shaft five, and the first bevel gear meshes with the second bevel gear.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. This device adopts an integrated design and adds a rear output design, enabling it to be modified into a four-wheel drive system. It features a simple structure, convenient operation, low failure rate, easy maintenance, and long service life. When there is a need to change the operation, it improves the replacement speed and ensures mechanical precision.

[0015] 2. All shafts and gears are integrated into a single gearbox body, and a multi-shaft parallel arrangement is adopted. Power is transmitted through direct meshing between gears, rather than using complex and additional transmission components, which effectively reduces the overall size and weight of the gearbox and makes it easier to install on equipment with limited space.

[0016] 3. The shifting mechanism consists of a shifting shaft and a shift fork on it. Shifting gears is achieved by directly moving the double gears. This mechanical shifting structure is simple, reliable, has a low failure rate, and provides the operator with a clear feel for the gear positions. Attached Figure Description

It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0025] Reference Figure 1As shown, this is a preferred embodiment of a direct-drive traction gearbox of the present invention, including a direct-drive traction gearbox body 7. A shift shaft 601 is internally connected to the direct-drive traction gearbox body 7, and a shift fork 602 is externally fixedly connected to the shift shaft 601. A shaft 101 is internally rotatably connected to the direct-drive traction gearbox body 7, and a gear 102 is externally fixedly connected to the shaft 101. A shaft 201 is internally rotatably connected to the direct-drive traction gearbox body 7, and a gear 202 is externally engaged with the shaft 201. A gear 303 is externally engaged with the shaft 201. Fork 602 is actuated between gear 202 and gear 303. Gear 4 204 is fixedly connected to the outside of shaft 201. Gear 4 204 meshes with gear 1 102. Shaft 3 301 is rotatably connected inside the direct-drive traction gearbox 7. Gear 5 302 and gear 6 303 are fixedly connected to the outside of shaft 301. Shaft 4 401 is rotatably connected inside the direct-drive traction gearbox 7. Gear 7 402 and gear 8 403 are fixedly connected to the outside of shaft 401.

[0026] Shaft 101 is connected to the engine output end, driving gear 102 to rotate. Gear 102 then drives gear 4 204, which meshes with it, to rotate, thereby driving shaft 201 to rotate. Shaft 201 drives the double gears, namely gear 202 and gear 3 203, to rotate synchronously. This actuates shift shaft 601, causing gear 202 and gear 3 203 to slide along shaft 201, allowing gear 202 and gear 3 203 to mesh with gear 6 303, gear 7 402, and gear 8 403 respectively. When gear 3 203 meshes with gear 6 303, it drives shaft 301 to rotate. When gear 202 meshes with gear 7 402, or gear 3 203 meshes with gear 8 403, it drives shaft 401 to rotate, thus forming three gears. This allows the equipment to select the most suitable gear according to different load and speed requirements, improving operating efficiency and adaptability.

[0027] Reference Figures 1-5 As shown, gear 202 and gear 3 203 are fixedly connected, and gear 202 and gear 3 203 constitute a double gear.

[0028] Reference Figures 1-5 As shown, shift shaft 601 extends to the outside of the direct-connect traction gearbox body 7, and shaft 401 extends to the outside of the direct-connect traction gearbox body 7.

[0029] Reference Figures 1-5 As shown, gear 202 and gear 3203 are engaged with gear 6303, gear 7402 and gear 8403 respectively by shifting the shift shaft 601, and gear 5302 is engaged with gear 7402.

[0030] Reference Figures 1-5 As shown, the first bevel gear 404 is fixedly connected to the outside of shaft 401, and shaft 501 is rotatably connected inside the direct-drive traction gearbox body 7, with shaft 501 passing through the direct-drive traction gearbox body 7.

[0031] Reference Figures 1-5 As shown, a second bevel gear 502 is fixedly connected to the outside of shaft 501, and the first bevel gear 404 meshes with the second bevel gear 502.

[0032] The rotation of shaft 401 can drive the first bevel gear 404 to rotate, which in turn drives the second bevel gear 502 that meshes with it to rotate, and finally drives shaft 501 to rotate. Shaft 501 serves as the walking output shaft. Through the meshing of a pair of bevel gears, namely the first bevel gear 404 and the second bevel gear 502, the power transmission direction is changed by 90 degrees. This is a typical requirement for traction equipment, which can convert the longitudinal power transmitted by the engine into lateral output, thereby driving the wheels or tracks.

[0033] The specific implementation process is as follows: Shaft 101 is connected to the engine output end, driving gear 102 to rotate. Gear 102 then drives gear 4204, which meshes with it, to rotate, thereby driving shaft 201 to rotate. Shaft 201 drives the double gear, namely gear 202 and gear 3203, to rotate synchronously. This actuates shift shaft 601, causing gear 202 and gear 3203 to slide along shaft 201, allowing gear 202 and gear 3203 to mesh with gear 6303, gear 7402, and gear 8403 respectively. When gear 3203 meshes with gear 6303, it drives shaft 301 to rotate. When gear 222 meshes with gear 7402, or gear 3203 meshes with gear 8403, it drives shaft 401 to rotate, thus forming three gears. This allows the equipment to select the most suitable gear according to different load and speed requirements, improving operating efficiency and adaptability.

[0034] The rotation of shaft 401 can drive the first bevel gear 404 to rotate, which in turn drives the second bevel gear 502 that meshes with it to rotate, and finally drives shaft 501 to rotate. Shaft 501 serves as the walking output shaft. Through the meshing of a pair of bevel gears, namely the first bevel gear 404 and the second bevel gear 502, the power transmission direction is changed by 90 degrees. This is a typical requirement for traction equipment, which can convert the longitudinal power transmitted by the engine into lateral output, thereby driving the wheels or tracks.
