Description

Technical Field

[0001] This invention relates to a walking device for tracked plant protection machinery used in agriculture, forestry, and sanitation fields, and particularly to a transmission method for a gear transmission box suitable for a tracked chassis. Background Technology

[0002] Tracked machinery is characterized by its ability to cross obstacles and trenches and move on various complex working surfaces. Currently, the main methods for controlling the movement and steering of tracked equipment are mechanical control and electronic control.

[0003] The mechanical control method involves the engine power being transmitted through a mechanical transmission box, from the input shaft to an output shaft via an intermediate shaft, and then through a central transmission bevel gear to two sets of high-torque steering clutches and brakes. The internal combustion engine power of the equipment's traveling mechanism is also transmitted through the mechanical transmission box, from the input shaft to the intermediate shaft to two output shafts. The rotation direction of these two output shafts is fixed, enabling the vehicle to move forward or backward. Alternatively, the vehicle can be turned left or right by manually engaging or disengaging the clutches to change the rotation direction of one of the output shafts or by braking one of the output shafts. However, this transmission box, where the traveling and steering of agricultural equipment are achieved by manually engaging or disengaging the mechanical clutches within the transmission box, is structurally complex, inconvenient to operate, and cannot achieve automated control.

[0004] The electronic control method involves automated remote control of the walking and steering mechanisms of the aforementioned agricultural equipment. The transmission box of this walking device converts the engine's power output shaft from a single, fixed-direction shaft into two controllable-direction output shafts. These controllable-direction output shafts are connected to the left and right half-shaft drive wheel systems, enabling the vehicle to move forward, backward, or turn. This method is convenient, flexible, and reliable. Furthermore, a long-distance wireless remote control of the electromagnetic clutch can be used to achieve automated control of the vehicle's forward, backward, or turning movements. However, the drive speed of the left and right output shafts of this transmission box is singular, making it impossible to adjust the drive speed of the left and right output shafts as needed. This fails to meet the requirements for rapid forward movement, slow forward movement, rapid turning, slow turning, and backward movement, resulting in low working efficiency for the tracked vehicle. Summary of the Invention

[0042] This embodiment also provides a transmission method for a gear transmission box based on a tracked chassis, specifically:

[0043] Power is output from the engine to the input shaft S1. The clockwise rotation of the input shaft S1 drives the first gear Z1 to rotate clockwise. The clockwise rotation of the first gear Z1 drives the second gear Z2 and the third gear Z3 to rotate counter-clockwise. The counter-clockwise rotation of the second gear Z2 and the third gear Z3 drives the second gear shaft S2 and the third gear shaft S3 to rotate counter-clockwise, respectively. Initially, the first electromagnetic clutch C1, the second electromagnetic clutch C2, the third electromagnetic clutch C3, the right electromagnetic clutch C4, and the left electromagnetic clutch C5 are all disengaged. The left drive wheel on the left track of the tracked chassis is connected to the output shaft S16 of the left wheel-side reducer, and the right drive wheel on the right track of the tracked chassis is connected to the output shaft S12 of the right wheel-side reducer. Ultimately, this enables the tracked vehicle to move forward slowly, turn slowly, move forward quickly, turn quickly, and move backward, as detailed below:

[0044] (1) When the third electromagnetic clutch C3 in the transmission box is in the closed state, and the first electromagnetic clutch C1 and the second electromagnetic clutch C2 are both in the open state, the input shaft S1 rotates forward, driving the first gear Z1 to rotate forward. The first gear Z1 rotates forward, driving the third gear Z3 to rotate in reverse. The third gear Z3 rotates in reverse, driving the third gear shaft S3 to rotate in reverse. The third gear shaft S3 rotates in reverse and transmits the reverse rotation to the seventh gear shaft S7 via the third electromagnetic clutch C3. The seventh gear shaft S7 drives the seventh gear Z7 to rotate in reverse. The seventh gear Z7 rotates in reverse, driving the sixth gear Z6 to rotate forward. The sixth gear Z6 rotates in forward, driving the first reducer output shaft S6 to rotate forward. The first reducer output shaft S6 rotates in forward, driving the first bevel gear Z8 to rotate forward. The first bevel gear Z8 drives the second bevel gear Z9 to rotate in reverse. The power is transmitted from this pair of bevel gears to the long shaft S8, causing the long shaft S8 to rotate in reverse. The long shaft S8 is equipped with half of the right electromagnetic clutch C4 and the left electromagnetic clutch C5 at each end. At this time:

[0045] If both the right-side electromagnetic clutch C4 and the left-side electromagnetic clutch C5 at both ends of the long shaft S8 are in the closed state, then power is transmitted from the long shaft S8 to the left-side wheel-side reducer and the right-side wheel-side reducer respectively, causing the ninth gear shaft S9 and the thirteenth gear shaft S13 to rotate in reverse. The reverse rotation of the ninth gear shaft S9 and the thirteenth gear shaft S13 respectively drives the tenth gear Z10 and the sixteenth gear Z16 to rotate in reverse. The reverse rotation of the tenth gear Z10 and the sixteenth gear Z16 respectively drives the eleventh gear Z11 and the seventeenth gear Z17 to rotate in the forward direction. The forward rotation of the eleventh gear Z11 and the seventeenth gear Z17 respectively drives the tenth gear shaft S10 and the fourteenth gear shaft S14 to rotate in the forward direction. The forward rotation of the tenth gear shaft S10 and the fourteenth gear shaft S14 respectively drives the twelfth gear Z12 and the eighteenth gear Z18 to rotate in the forward direction. The forward rotation of the twelfth gear Z12 and the eighteenth gear Z18 respectively... The thirteenth gear Z13 and the nineteenth gear Z19 rotate in reverse. The reverse rotation of the thirteenth gear Z13 and the nineteenth gear Z19 respectively drives the eleventh gear shaft S11 and the fifteenth gear shaft S15 to rotate in reverse. The reverse rotation of the eleventh gear shaft S11 and the fifteenth gear shaft S15 respectively drives the fourteenth gear Z14 and the twentieth gear Z20 to rotate in reverse.

[0046] If the left electromagnetic clutch C5 is closed and the right electromagnetic clutch C4 is open, then power is only transmitted to the left wheel-side reducer, the left track moves and the right track is stationary, the tracked vehicle turns towards the stationary track side, realizing the slow right turn of the tracked chassis;

[0047] If the left electromagnetic clutch C5 is disengaged and the right electromagnetic clutch C4 is engaged, power is only transmitted to the right wheel-side reducer, the right track moves while the left track remains stationary, and the tracked vehicle turns towards the stationary track side, achieving a slow left turn of the tracked chassis.

[0048] (2) When the second electromagnetic clutch C2 in the transmission box is engaged, and the first electromagnetic clutch C1 and the third electromagnetic clutch C3 are both disengaged, the input shaft S1 rotates forward and transmits the forward rotation to the output shaft S6 of the first reducer via the second electromagnetic clutch C2. The output shaft S6 of the first reducer rotates forward, driving the first bevel gear Z8 to rotate forward. The first bevel gear Z8 drives the second bevel gear Z9 to rotate in reverse. The power is transmitted from this pair of bevel gears to the long shaft S8, causing the long shaft S8 to rotate in reverse. The long shaft S8 is equipped with half of the right electromagnetic clutch C4 and the left electromagnetic clutch C5 at each end. At this time:

[0049] If the right electromagnetic clutch C4 and the left electromagnetic clutch C5 at both ends of the long shaft S8 are both closed, the power is transmitted from the long shaft S8 to the left wheel-side reducer and the right wheel-side reducer respectively. After passing through the two-stage reduction of the left wheel-side reducer and the right wheel-side reducer, the power is finally output from the output shaft S12 of the right wheel-side reducer and the output shaft S16 of the left wheel-side reducer, driving the left drive wheel and the right drive wheel in the two tracks, realizing the rapid forward movement of the tracked chassis.

[0050] If the left electromagnetic clutch C5 is closed and the right electromagnetic clutch C4 is open, then power is only transmitted to the left wheel-side reducer, the left drive wheel in the left track moves, and the right drive wheel in the right track is stationary. The track chassis turns towards the stationary track side, realizing the rapid right turn of the track chassis.

[0051] If the left electromagnetic clutch C5 is disengaged and the right electromagnetic clutch C4 is engaged, power is transmitted only to the right wheel-side reducer. The right drive wheel in the right track moves while the left drive wheel in the left track remains stationary. The track chassis turns towards the stationary track side, achieving a rapid left turn of the track chassis.

[0052] (3) When the first electromagnetic clutch C1 in the transmission box is engaged, and the second electromagnetic clutch C2 and the third electromagnetic clutch C3 are disengaged, the input shaft S1 rotates forward, driving the first gear Z1 to rotate forward. The first gear Z1 rotates forward, driving the second gear Z2 to rotate in reverse. The second gear Z2 rotates in reverse, driving the second gear shaft S2 to rotate in reverse. The second gear shaft S2 rotates in reverse and transmits the reverse rotation to the fourth gear shaft S4 via the first electromagnetic clutch C1. The fourth gear shaft S4 rotates in reverse, driving the fourth gear Z4 to rotate in reverse. The fourth gear Z4 rotates in reverse, driving the fifth gear Z5 to rotate forward. The fifth gear Z5 rotates in forward, driving the sixth gear Z6 to rotate in reverse. The sixth gear Z6 rotates in reverse, driving the first reducer output shaft S6 to rotate in reverse. The first reducer output shaft S6 rotates in reverse, driving the first bevel gear Z8 to rotate in reverse. The first bevel gear Z8 rotates in reverse, driving the second bevel gear Z9 to rotate forward. Power is transmitted from this pair of bevel gears to the long shaft S8, causing the long shaft S8 to rotate forward. The long shaft S8 is equipped with half of the right electromagnetic clutch C4 and half of the left electromagnetic clutch C5 at each end. At this time:

[0053] If the right electromagnetic clutch C4 and the left electromagnetic clutch C5 at both ends of the long shaft S8 are both closed, the power is transmitted from the long shaft S8 to the left wheel-side reducer and the right wheel-side reducer respectively. After passing through the two-stage reduction of the left wheel-side reducer and the right wheel-side reducer, the power is finally output from the output shaft S12 of the right wheel-side reducer and the output shaft S16 of the left wheel-side reducer, driving the left drive wheel and the right drive wheel in the two tracks to move, realizing the backward movement of the tracked chassis.

[0054] If the left electromagnetic clutch C5 is closed and the right electromagnetic clutch C4 is open, then power is only transmitted to the left wheel-side reducer, the left drive wheel in the left track moves, and the right drive wheel in the right track is stationary. The track chassis turns towards the moving track side, thereby realizing the reverse left turn of the track chassis.

[0055] If the left electromagnetic clutch C5 is disengaged and the right electromagnetic clutch C4 is engaged, power is transmitted only to the right wheel-side reducer. The right drive wheel in the right track moves while the left drive wheel in the left track remains stationary. The track chassis turns towards the moving track side, thus achieving the reverse right turn of the track chassis.

[0056] The reducer in this embodiment mainly achieves speed reduction by using two meshing gears with different diameters, resulting in different rotational speeds. The specific diameters of the gears are designed according to actual needs. The second gear Z2 and the third gear Z3 have the same diameter, but the diameter of the third gear Z3 is larger than that of the first gear Z1. The first gear Z1 drives the transmission from the second gear Z2 to the third gear Z3, causing speed reduction. The fourth gear Z4 and the fifth gear Z5 have the same diameter, but the diameter of the fifth gear Z5 is smaller than that of the sixth gear Z6. The fifth gear Z5 drives the transmission from the sixth gear Z6, causing speed reduction. The seventh gear Z7 and the sixth gear Z6 have the same diameter. The sixteenth gear Z16 has a smaller diameter than the seventeenth gear Z17. The sixteenth gear Z16 drives the transmission from the seventeenth gear Z17, causing speed reduction. The eighteenth gear Z18 has a smaller diameter than the nineteenth gear Z19. The eighteenth gear Z18 drives the transmission from the nineteenth gear Z19, causing speed reduction. The twentieth gear Z20 has a smaller diameter than the twenty-first gear Z21. The twentieth gear Z20 drives the transmission from the twenty-first gear Z21, causing speed reduction. The diameter of the tenth gear Z10 is smaller than that of the eleventh gear Z11. The transmission from the tenth gear Z10 to the eleventh gear Z11 results in speed reduction. The diameter of the twelfth gear Z12 is smaller than that of the thirteenth gear Z13. The transmission from the twelfth gear Z12 to the thirteenth gear Z13 results in speed reduction. The diameter of the fourteenth gear Z14 is smaller than that of the fifteenth gear Z15. The transmission from the fourteenth gear Z14 to the fifteenth gear Z15 results in speed reduction.

Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art fall within the scope of protection of this invention.
