[0037] Example

[0038] Please also refer to Figure 1 and Figure 2 This embodiment provides a drive system applied to vehicles, including but not limited to tractors. The drive system includes a power mechanism 100, a power take-off mechanism 200, and a first switching mechanism 300.

[0039] The power mechanism 100 includes a drive member 110 and a drive shaft 120. The drive end of the drive member 110 is connected to the drive shaft 120, and the drive shaft 120 is provided with a first engagement part 121.

[0040] The power take-off mechanism 200 includes a power take-off shaft 210. The axis of the power take-off shaft 210 coincides with the axis of the drive shaft 120, and a second engagement part 211 is provided on the power take-off shaft 210.

[0041] The first switching mechanism 300 includes a first engaging sleeve 310 and a first actuating assembly 320. The first engaging sleeve 310 is slidably sleeved on the first engaging portion 121 along the axial direction of the drive shaft 120. The actuating end of the first actuating assembly 320 is connected to the first engaging sleeve 310 and is used to drive the first engaging sleeve 310 to slide along the axial direction of the drive shaft 120, so that the first engaging sleeve 310 engages or disengages from the second engaging portion 211.

[0042] Understandably, during the sliding of the first engagement sleeve 310 along the axial direction of the drive shaft 120, the first engagement sleeve 310 always remains engaged with the first engagement part 121.

[0043] When the aforementioned drive system is operating, the drive end of the drive component 110 drives the drive shaft 120 to rotate, continuously outputting power through the drive shaft 120. When it is necessary to drive an external accessory device, the actuating end of the first actuating component 320 drives the first engaging sleeve 310 to slide along the axial direction of the drive shaft 120, so that the first engaging sleeve 310 maintains engagement with the first engaging part 121 while also engaging with the second engaging part 211. At this time, the drive shaft 120 is connected to the power take-off shaft 210 in sequence through the first engaging part 121, the first engaging sleeve 310, and the second engaging part 211, which can drive the power take-off shaft 210 to rotate, thereby driving the external accessory device through the power take-off shaft 210 without the need for an additional power source, saving space and cost.

[0044] Conversely, the actuating end of the first actuating component 320 drives the first engaging sleeve 310 to slide in the opposite direction along the axis of the drive shaft 120, so that the first engaging sleeve 310 is separated from the second engaging part 211, thereby preventing the drive shaft 120 from being connected to the power take-off shaft 210 and stopping the drive of the external accessory device.

[0045] In some embodiments, the drive unit 110 is a geared motor, and the shaft of the geared motor is connected to the drive shaft 120 through a gear set.

[0046] In some embodiments, the first actuation assembly 320 includes a first actuation element 321, a first linkage structure 322, and a first paddle 323.

[0047] The first actuating element 321 is connected to the first paddle 323 via the first connecting rod structure 322, and is used to drive the first paddle 323 to move along the axial direction of the drive shaft 120. In addition, the first paddle 323 is connected to the first engagement sleeve 310.

[0048] In use, the first actuating element 321 drives the first paddle 323 to move along the axial direction of the drive shaft 120 via the first connecting rod structure 322. The first paddle 323 then actuates the first engagement sleeve 310, causing the first engagement sleeve 310 to slide along the axial direction of the drive shaft 120.

[0049] Optionally, the first actuating element 321 is a motor.

[0050] Furthermore, the outer wall of the first engagement sleeve 310 is provided with a first slot 311. The first slot 311 extends circumferentially along the drive shaft 120, and the first paddle 323 engages with the first slot 311.

[0051] In use, the first engagement sleeve 310 is always engaged with the first engagement part 121 and rotates with the drive shaft 120. Since the first slot 311 extends circumferentially along the drive shaft 120, the first paddle 323 is always engaged with the first slot 311 and does not affect the rotation process of the drive shaft 120.

[0052] Furthermore, the power take-off mechanism 200 also includes an output shaft 220 and an output gear set 230. The axis of the output shaft 220 is parallel to the axis of the power take-off shaft 210, and the output shaft 220 is connected to the power take-off shaft 210 through the output gear set 230.

[0053] In use, the output shaft 220 is directly connected to an external accessory device to output power. The power take-off shaft 210 drives the output shaft 220 to rotate through the output gear set 230, thereby driving the external accessory device.

[0054] In some embodiments, the drive shaft 120 is further provided with a third engagement portion 122.

[0055] Accordingly, the drive system also includes a shift mechanism 400, a second switching mechanism 500, a front axle mechanism 600, and a rear axle mechanism 700.

[0056] Please combine Figure 3 The shifting mechanism 400 includes a first driving gear 410, a second driving gear 420, a shifting shaft 430, a first driven gear 440, and a second driven gear 450.

[0057] The first driving gear 410 and the second driving gear 420 are both rotatably sleeved on the driving shaft 120 and are located on both sides of the third meshing part 122 along the axial direction of the driving shaft 120. The first driving gear 410 has a fourth meshing part 411 at one end facing the third meshing part 122, and the second driving gear 420 has a fifth meshing part 421 at one end facing the third meshing part 122.

[0058] The axis of the shift shaft 430 is parallel to the axis of the drive shaft 120, and the shift shaft 430 is connected to the front axle mechanism 600 and the rear axle mechanism 700 respectively.

[0059] The first driven gear 440 and the second driven gear 450 are both sleeved on the shift shaft 430, and the first driven gear 440 meshes with the first driving gear 410, and the second driven gear 450 meshes with the second driving gear 420.

[0060] Furthermore, the second switching mechanism 500 includes a second engaging sleeve 510 and a second actuating assembly 520. The second engaging sleeve 510 is slidably sleeved on the third engaging portion 122 along the axial direction of the drive shaft 120. The actuating end of the second actuating assembly 520 is connected to the second engaging sleeve 510 and is used to drive the second engaging sleeve 510 to slide along the axial direction of the drive shaft 120, so that the second engaging sleeve 510 engages or disengages with the fourth engaging portion 411, and engages or disengages with the fifth engaging portion 421.

[0061] Understandably, during the sliding of the second engagement sleeve 510 along the axial direction of the drive shaft 120, the second engagement sleeve 510 always remains engaged with the third engagement part 122.

[0062] In use, the actuating end of the second actuating assembly 520 drives the second engagement sleeve 510 to slide along the axial direction of the drive shaft 120, so that the second engagement sleeve 510 is engaged with the third engagement part 122 and also with the fourth engagement part 411. At this time, the drive shaft 120 is connected to the shift shaft 430 in sequence through the third engagement part 122, the second engagement sleeve 510, the fourth engagement part 411, the first drive gear 410 and the first driven gear 440, which can drive the shift shaft 430 to rotate, thereby driving the front axle mechanism 600 and the rear axle mechanism 700 through the shift shaft 430.

[0063] Alternatively, the actuating end of the second actuating assembly 520 can also drive the second engaging sleeve 510 to slide in the opposite direction along the axis of the drive shaft 120, so that the second engaging sleeve 510 is engaged with the third engaging part 122 and also with the fifth engaging part 421. At this time, the drive shaft 120 is connected to the shift shaft 430 in sequence through the third engaging part 122, the second engaging sleeve 510, the fifth engaging part 421, the second drive gear 420 and the second driven gear 450, which can also drive the shift shaft 430 to rotate, thereby driving the front axle mechanism 600 and the rear axle mechanism 700 through the shift shaft 430.

[0064] Understandably, the speed ratio of the first driving gear 410 and the first driven gear 440 is different from the speed ratio of the second driving gear 420 and the second driven gear 450. By switching between them, different reduction ratios can be achieved, thereby changing the rotational speed of the shift shaft 430 and realizing gear shifting.

[0065] Specifically, when the second engagement sleeve 510 engages only with the third engagement part 122, the drive shaft 120 is not connected to the shift shaft 430, and the aforementioned drive system is in neutral.

[0066] In addition, by matching different gears, the gears can output a certain speed to the front axle mechanism 600 and the rear axle mechanism 700, which can solve the problem of inconsistent wheel and axle speeds caused by the difference in the diameter of the front and rear wheels.

[0067] In some embodiments, the second toggle assembly 520 includes a second toggle member 521, a second linkage structure 522, and a second toggle piece 523.

[0068] The second actuating element 521 is connected to the second paddle 523 via the second connecting rod structure 522, and is used to drive the second paddle 523 to move along the axial direction of the drive shaft 120. In addition, the second paddle 523 is connected to the second engagement sleeve 510.

[0069] In use, the second actuating member 521 drives the second paddle 523 to move along the axial direction of the drive shaft 120 via the second linkage structure 522. The second paddle 523 then actuates the second engagement sleeve 510, causing the second engagement sleeve 510 to slide along the axial direction of the drive shaft 120.

[0070] Optionally, the second actuating element 521 also uses a motor.

[0071] Furthermore, the outer wall of the second engagement sleeve 510 is provided with a second slot 511. The second slot 511 extends circumferentially along the drive shaft 120, and the second paddle 523 engages with the second slot 511.

[0072] In use, the second engagement sleeve 510 is always engaged with the second engagement part 211 and rotates with the drive shaft 120. Since the second slot 511 extends circumferentially along the drive shaft 120, the second paddle 523 is always engaged with the second slot 511 and does not affect the rotation process of the drive shaft 120.

[0073] Please see Figure 4 Furthermore, the front axle mechanism 600 includes an input shaft 610, a differential gear set 620, a first wheel axle 630, and a second wheel axle 640.

[0074] One end of the input shaft 610 is connected to the shift shaft 430, and the other end of the input shaft 610 is connected to the first gear shaft 630 and the second gear shaft 640 respectively through the differential gear set 620.

[0075] Specifically, the axis of the input shaft 610 is parallel to the axis of the shift shaft 430, and the input shaft 610 is connected to the shift shaft 430 through a gear set.

[0076] In addition, the differential gear set 620 can change the rotation direction of the drive shaft, reduce speed and increase torque, solve the problem of the difference in speed between the left and right wheels when turning, and make the vehicle drive more smoothly.

[0077] Furthermore, the front axle mechanism 600 also includes a pair of planetary gear sets 650. One planetary gear set 650 is connected to the first axle 630, and the other planetary gear set 650 is connected to the second axle 640.

[0078] Specifically, the planetary gear set 650 includes a sun gear 651, a ring gear 652, a planet carrier 653, and planet gears 654. The sun gear 651 is connected to either a first gear shaft 630 or a second gear shaft 640. The ring gear 652 is fixedly mounted, possibly to a housing, and its axis coincides with the axis of the sun gear 651. The planet gears 654 are rotatably mounted on the planet carrier 653, positioned between the sun gear 651 and the ring gear 652, and mesh with both the sun gear 651 and the ring gear 652.

[0079] In operation, the first axle 630 or the second axle 640 drives the corresponding sun gear 651 to rotate, which in turn drives the planetary gears 654 to rotate. Since the ring gear 652 remains stationary, the planetary gears 654 also revolve around the axis of the sun gear 651, thereby driving the planet carrier 653 to rotate. The planet carrier 653 is used for output, achieving the effect of speed reduction and torque increase, thus realizing a larger torque output to meet the working conditions of the vehicle towing a large load.

[0080] It should be noted that the rear axle mechanism 700 also adopts the design of differential gear set 620 and planetary gear set 650, which will not be elaborated here.

[0081] In summary, when the aforementioned drive system is operating, the drive end of the drive component 110 drives the drive shaft 120 to rotate, continuously outputting power through the drive shaft 120, and driving the front axle mechanism 600 and the rear axle mechanism 700 through gear shifting. When it is necessary to drive external accessory devices, the actuating end of the first actuating component 320 drives the first engaging sleeve 310 to slide along the axial direction of the drive shaft 120, so that the first engaging sleeve 310 maintains engagement with the first engaging part 121 while also engaging with the second engaging part 211. At this time, the drive shaft 120 is connected to the power take-off shaft 210 in sequence through the first engaging part 121, the first engaging sleeve 310, and the second engaging part 211, which can drive the power take-off shaft 210 to rotate, thereby driving the external accessory devices through the power take-off shaft 210 without the need for an additional power source, saving space and cost. Conversely, the actuating end of the first actuating component 320 drives the first engaging sleeve 310 to slide in the opposite direction along the axis of the drive shaft 120, so that the first engaging sleeve 310 is separated from the second engaging part 211, thereby preventing the drive shaft 120 from being connected to the power take-off shaft 210 and stopping the drive of the external accessory device.

[0082] This embodiment also provides a vehicle including the above-described drive system.

[0083] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not limiting, and thus other examples of the exemplary embodiments may have different values.

[0085] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention.
