DETAILED DESCRIPTION

[0036] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0037] In the description of the present invention, it should be understood that “plurality” means two or more than two, unless otherwise clearly defined.

[0038] See also Figures 1 to 7 The present invention provides an air suspension tractor chassis layout structure, drive system and method: comprising a drive chassis 101, a frame chassis 102 and a junction box 103, a movable bracket 104, a flip frame 105, a push-out screw rod 106, a push-out motor 107, a support member and a regulating member, wherein the support member comprises a support bracket 201, a lifting screw rod 202, a friction pad 203 and a synchronous drive component, the regulating member comprises a sliding bracket 301, a sliding screw rod 302, a sliding motor 303 and a flip component, and the synchronous drive component comprises a synchronous shaft 207. 04, synchronous bevel gear 205, driving bevel gear 206 and synchronous motor 207, the flip component includes a sleeve gear 304, a driving gear plate 305, a moving screw 306 and a moving motor 307. The above-mentioned solution solves the problem that the existing tractor chassis layout structure is fixed to each other during installation and layout, and the main power components are replaced due to the layout structure of the power device at the bottom of the vehicle. The whole process is relatively cumbersome, which makes the existing layout structure very inconvenient when the corresponding situation requires replacement and installation.

[0039] Furthermore, the two junction boxes 103 are respectively fixedly mounted on one side of the driving chassis 101 and the frame chassis 102, the movable bracket 104 is slidably mounted on the frame chassis 102, the flip frame 105 is slidably connected to the driving chassis 101, and is rotatably mounted on the movable bracket 104, the ejection screw rod 106 is threadedly connected to the movable bracket 104, and is rotatably mounted on the frame chassis 102, the output shaft of the ejection motor 107 is connected to the ejection screw rod 106, and the ejection motor 107 is fixedly mounted on the frame chassis 102, the supporting member is connected to the frame chassis 102, and is used to support and lift the entire frame chassis 102, and the regulating member is connected to the movable bracket 104, and is used to drive and regulate the flip frame 105 and the driving chassis 101 accordingly.

[0040] Specifically, a corresponding drive control mechanism is provided inside the drive chassis 101, and corresponding drive wheels are provided on the drive chassis 101. The provided drive wheels are controlled by the drive control mechanism inside the drive chassis 101, wherein all wiring of the drive control mechanism is concentrated in the junction box 103 on the side of the drive chassis 101, and the junction box 103 provided on the frame chassis 102 is connected to the driving system of the vehicle body and is connected to the junction box 103 on the side of the drive chassis 101 through corresponding wiring. In actual use, the user can place the wiring externally and then protect it by providing a corresponding shell. At the same time, an internal wiring structure can also be opened according to actual conditions to avoid the wires being exposed to the outside.

[0041] The two junction boxes 103 are used to connect the driving system to the drive control mechanism within the drive chassis 101. During actual operation, the user can drive and control the vehicle through the driving system. In this solution, the drive control mechanism within the drive chassis 101 can steer by controlling the differential speed of the wheels on both sides. The essence of differential steering technology is that by precisely controlling the speed difference between the left and right wheels, stable rotation of the vehicle body can be ensured even in the absence of steering wheel response or asynchronous rotation.

[0042] When the vehicle turns, the wheel's travel path forms an arc. To compensate for the difference between the left and right wheels, the inner wheel needs to rotate slightly slower, while the outer wheel needs to rotate faster to fill the distance difference. This technology allows the vehicle to have greater flexibility in narrow spaces or complex terrain. The use of differential steering can simplify the wheel mounting structure on the drive chassis 101 and also improve the flexibility of the tractor.

[0043] The movable bracket 104 cooperates with the slide groove provided at the bottom of the frame chassis 102, and the cylindrical turning frame 105 is rotatably provided in the movable bracket 104. The turning frame 105 is connected to the driving chassis 101 through the regulating member. At the same time, a threaded hole matching the pushing screw 106 is provided on the plate connected to the frame chassis 102 on the side of the movable bracket 104. The pushing screw 106 is driven by the pushing motor 107, which makes it convenient for the user to drive the movable bracket 104 through the pushing motor 107 and the pushing screw 106. In this way, the entire driving chassis 101 can be moved out by utilizing the movement of the movable bracket 104 and the driving of the driving chassis 101 by the regulating member.

[0044] When the chassis of the vehicle body needs to be inspected and repaired, all the wiring installed on the two junction boxes 103 of the driving chassis 101 and the frame chassis 102 are first removed, and then the frame chassis 102 is lifted up by the supporting member. After the frame chassis 102 is lifted, the push-out motor 107 cooperates with the push-out screw rod 106 to drive the movable bracket 104 to move, so that the movable bracket 104 moves to the side of the frame chassis 102. After the adjustment of the movable bracket 104 is completed, the driving chassis 101 is driven to move on the movable bracket 104 by the regulating member, and then the driving chassis 101 is moved out for inspection and repair. At the same time, the user can also flip the driving chassis 101 through the regulating member according to actual conditions, and then the operator can quickly and conveniently install the power drive structure of the vehicle chassis according to actual conditions by rearranging the existing vehicle bottom drive structure.

[0045] Furthermore, the two supporting brackets 201 are respectively slidably installed on both sides of the frame chassis 102; the two lifting screw rods 202 are respectively threadedly connected to the two supporting brackets 201 and are rotatably installed on both sides of the frame chassis 102; the two friction pads 203 are respectively fixedly installed on the two supporting brackets 201; the synchronous driving component is connected to the frame chassis 102, and is used to synchronously drive the two lifting screw rods 202.

[0046] Furthermore, the synchronization shaft 204 is rotatably mounted on the frame chassis 102; the two synchronization bevel gears 205 are fixedly mounted on both sides of the synchronization shaft 204; the two driving bevel gears 206 are respectively engaged with the two synchronization bevel gears 205, and are respectively fixedly mounted on the top of the two lifting screw rods 202; the output shaft of the synchronization motor 207 is connected to the synchronization shaft 204, and the synchronization motor 207 is fixedly mounted on one side of the frame chassis 102.

[0047] When this embodiment is in use, the supporting brackets 201 are installed on both sides of the frame chassis 102, and the plates that cooperate with the supporting brackets 201 and the internal guide grooves of the frame chassis 102 are provided with threaded holes that match the lifting screw rods 202. The tops of the two lifting screw rods 202 are fixed with the driving bevel gears 206, and the two driving bevel gears 206 correspond to the two synchronous bevel gears 205 fixedly sleeved on the synchronous shaft 204. The synchronous bevel gears 205 provided on the two synchronous shafts 204 can adjust the transmission direction of the two driving bevel gears 206 by changing the matching position. In this solution, the two synchronous bevel gears 205 need to drive the two driving bevel gears 206 to ensure the consistency of the steering, thereby synchronously driving the lifting screw rods 202 on both sides, and the synchronous shaft 204 is driven by the synchronous motor 207;

[0048] The synchronous shaft 204 is driven to rotate by the synchronous motor 207, and then the two synchronous bevel gears 205 fixedly mounted on the synchronous shaft 204 drive the two driving bevel gears 206 and the lifting screw 202 to rotate. When the lifting screws 202 on both sides rotate, the two supporting brackets 201 can slide on the frame chassis 102, thereby supporting and lifting the entire vehicle body. When lifting, the supporting bracket 201 can ensure the stability of the support by the friction pad 203 fixedly installed at the bottom.

[0049] Furthermore, the sliding bracket 301 is slidably connected to the flip frame 105 and is fixedly installed on one side of the driving chassis 101; the sliding screw 302 is threadedly connected to the sliding bracket 301 and is rotatably installed on one side of the flip frame 105; the output shaft of the sliding motor 303 is connected to the sliding screw 302, and the sliding motor 303 is fixedly installed on one side of the flip frame 105; the flip component is connected to the flip frame 105 for driving the flip frame 105 to rotate.

[0050] Furthermore, the sleeve gear 304 is fixedly mounted on one side of the flip frame 105; the driving gear plate 305 is engaged with the sleeve gear 304 and is slidably mounted on one side of the movable bracket 104; the output shaft of the moving motor 307 is connected to the moving screw 306, and the moving motor 307 is fixedly mounted on one side of the movable bracket 104.

[0051] When in use, the sliding bracket 301 cooperates with the guide groove provided inside the flip frame 105. The sliding bracket 301 is fixedly provided on the side of the driving chassis 101. The sliding bracket 301 is provided with a threaded hole that cooperates with the sliding screw 302. The sliding screw 302 is driven by the sliding motor 303, so that the sliding motor 303 cooperates with the sliding screw 302 to realize the driving of the sliding bracket 301 and the driving chassis 101.

[0052] The sleeve gear 304 is fixedly arranged at the side end of the flip frame 105, and the driving tooth plate 305 cooperates with the connecting bracket provided on the back side of the movable bracket 104. The driving tooth plate 305 is provided with a threaded hole that cooperates with the moving screw rod 306. The moving screw rod 306 is driven by the moving motor 307, so that the sleeve gear 304 and the flip frame 105 are driven to rotate by driving the driving tooth plate 305.

[0053] After the movable bracket 104 moves to the side of the frame chassis 102, the sliding motor 303 can cooperate with the sliding screw 302 to drive the sliding bracket 301 and the driving chassis 101, thereby completely moving the driving chassis 101 out from the side of the frame chassis 102, so that the surface of the driving chassis 101 will not be blocked by the frame chassis 102, which is convenient for users to directly maintain the components on the driving chassis 101. It should be noted that before the movable bracket 104 moves, the entire chassis will be lifted up under the action of the supporting member, so the driving chassis 101 can be directly moved to the frame On the corresponding side of the chassis 102, after the driving chassis 101 is completely moved out, the moving motor 307 can cooperate with the moving screw rod 306 to drive the driving gear plate 305, and then the driving gear plate 305 cooperates to drive the sleeve gear 304 and the flip frame 105 to rotate. In order to avoid the interference between the driving gear plate 305 and the plate structure during the movement, the frame chassis 102 is provided with a side through groove at the corresponding position. At the same time, since the entire supporting member is in a raised state, the corresponding plate will not affect the movement of the driving gear plate 305 after moving downward, thereby facilitating the user to install the driving chassis 101.

[0054] Preferably, the installation assembly provided by the present invention further includes an extension support frame 401, a pulley support plate 402, an extension screw rod 403 and an extension motor 404.

[0055] Furthermore, the two extension support frames 401 are respectively slidably installed on the two supporting frames 201; the pulley support plate 402 is fixedly installed on the bottom of each extension support frame 401; the two exhibition screw rods 403 are respectively threadedly connected to the two extension support frames 401, and are respectively rotatably installed on the two supporting frames 201; the output shafts of the two exhibition motors 404 are respectively connected to the two exhibition screw rods 403, and the two exhibition motors 404 are respectively fixedly installed on the two supporting frames 201.

[0056] When the present embodiment is in use, the extension support frame 401 is slidably provided on each of the support brackets 201, the pulley support plate 402 is fixedly installed at the bottom of each of the extension support frames 401, and multiple sets of pulley shafts are provided at the bottom of the pulley support plate 402. The extension screw rod 403 matches the threaded hole on the side plate of the extension support frame 401, and the extension screw rod 403 is driven by the extension motor 404;

[0057] After the driving chassis 101 is moved sideways and expanded, the center of balance of the entire frame during support may be slightly offset. Therefore, after support is performed, the extension support frame 401 on the support bracket 201 can be moved out from the side of the support bracket 201 with the cooperation of the expansion motor 404 and the expansion screw rod 403. When the extension support frame 401 moves, the pulley support plate 402 can ensure the stability of the movement of the extension support frame 401, and the friction pad 203 arranged at the bottom of the support bracket 201 can ensure the stability of the entire support position. In this way, by expanding the support structure, the support stability of the support structure can be guaranteed after the driving chassis 101 is subsequently moved out. After the operation is completed, the extension support frame 401 can be moved and retracted, so that the vehicle body will not be affected by the support structure during normal operation.

[0058] See also Figure 8 A drive system for an air suspension tractor is applied to the chassis arrangement structure of the air suspension tractor, and is characterized by comprising a control instruction issuing module 1, a scheme setting module 2, a motor parameter acquisition module 3, and an execution module 4, wherein the control instruction issuing module 1 is connected to the execution module 4, the scheme setting module 2 is connected to the execution module 4, and the execution module 4 is connected to the motor parameter acquisition module 3;

[0059] The control instruction issuing module 1 is used to generate and output the operation instruction;

[0060] The scheme setting module 2 is used for the customer to set in advance a drive system arrangement scheme for the tractor for rearranging the bottom drive system;

[0061] The motor parameter acquisition module 3 is used to monitor the operating parameters of all motors;

[0062] The execution module 4 executes the drive system arrangement scheme in the scheme setting module 2 based on the operation instruction of the control instruction issuing module 1 and the real-time motor operating parameters obtained by the motor parameter obtaining module 3;

[0063] Specifically, the control command issuing module 1 is mainly used to generate and output the two commands of chassis expansion and folding. Secondly, the user can also output the corresponding chassis flip command according to the actual situation. The scheme setting module 2 is used to set the drive system layout scheme for chassis expansion and folding in advance. The corresponding drive system layout scheme mainly includes controlling the driving sequence of each motor and controlling the operating parameters of each motor;

[0064] The motor parameter acquisition module 3 is used to provide feedback on the real-time operating parameters of each motor, so as to better implement the drive system layout scheme set by the scheme setting module 2;

[0065] When the scheme setting module 2 receives a request to unfold the vehicle chassis, the scheme setting module 2 will call out the set chassis unfolding drive system layout scheme;

[0066] The above-mentioned chassis deployment drive system layout mainly includes:

[0067] First, the synchronous motor 207 is controlled to work, and the motor parameter acquisition module 3 monitors and feeds back the operating parameters of the synchronous motor 207 so that the supporting brackets 201 on both sides can lift the entire vehicle body. The lifting height can be calculated and determined based on the rotation operating parameters of the synchronous motor 207;

[0068] After the lifting of the supporting bracket 201 is completed, the two unfolding motors 404 are controlled to unfold the extension support frames 401 provided on the two supporting brackets 201, and then the pushing motor is controlled to drive the movable bracket 104 to move on the frame chassis 102;

[0069] After the frame chassis 102 moves a set distance, the driving chassis 101 can be moved out by controlling the sliding motor 303 to cooperate with the sliding screw 302 and the sliding bracket 301, thereby completing the deployment of the frame chassis 102 structure;

[0070] At the same time, the chassis folding drive system layout mainly includes:

[0071] First, the driving chassis 101 and the movable support 104 are moved and reset in sequence by controlling the sliding motor 303 and the pushing motor 107, and then the extension motor 404 is controlled to retract the extension support on the supporting support 201, and finally the supporting support 201 is retracted by controlling the synchronous motor 207;

[0072] When the user issues a flip command through the control command issuing module 1, a judgment unit is provided inside the execution module 4. When receiving the flip command, it is necessary to judge whether the chassis deployment drive system layout plan has been completed. Only after the chassis deployment drive system layout plan has been implemented can the flip command be implemented to avoid unreasonable manipulation of the corresponding structure due to user's misoperation, thereby avoiding collisions and the like.

The tops of the two lifting screw rods 202 are fixed with the driving bevel gears 206, and the two driving bevel gears 206 correspond to the two synchronous bevel gears 205 fixedly sleeved on the synchronous shaft 204. The synchronous bevel gears 205 provided on the two synchronous shafts 204 can adjust the transmission direction of the two driving bevel gears 206 by changing the matching position. In this solution, the two synchronous bevel gears 205 need to drive the two driving bevel gears 206 to ensure the consistency of the steering, thereby synchronously driving the lifting screw rods 202 on both sides, and the synchronous shaft 204 is driven by the synchronous motor 207;

[0077] The synchronous shaft 204 is driven to rotate by the synchronous motor 207, and then the two synchronous bevel gears 205 fixedly mounted on the synchronous shaft 204 drive the two driving bevel gears 206 and the lifting screw 202 to rotate. When the lifting screws 202 on both sides rotate, the two supporting brackets 201 can slide on the frame chassis 102, thereby supporting and lifting the entire vehicle body. When lifting, the supporting bracket 201 can ensure the stability of the support by the friction pad 203 fixedly installed at the bottom.

[0079] S4: After the movable bracket 104 is adjusted, the driving chassis 101 is moved on the movable bracket 104 by the regulating member, and the driving chassis 101 is removed for inspection. At the same time, the user can also flip the driving chassis 101 by the regulating member according to actual conditions.

[0080] Specifically, the movable bracket 104 cooperates with the slide groove provided at the bottom of the frame chassis 102, and the cylindrical turning frame 105 is rotatably provided in the movable bracket 104.
