Description

Technical Field

[0001] The present invention relates to the technical field of gearboxes, in particular to a gearbox with adaptive load adjustment for an electric loader. Background Art

[0002] Load regulation is a measure of a power supply's ability to maintain a constant output voltage when the output current or load changes. Ideally, load regulation should be zero, meaning the power supply's output voltage remains constant regardless of the load. Good load regulation ensures the power supply provides the required stable voltage to the circuit or system.

[0003] Existing gearboxes with load regulation are often composed of two parts: a speed transmission mechanism and a speed control mechanism. The main function of the speed transmission mechanism is to change the value and direction of torque and speed; the main function of the control mechanism is to control the transmission mechanism to achieve the change of the transmission ratio.

[0004] In the existing technology, by combining load regulation technology with the gearbox, the gear shifting timing and transmission ratio of the gearbox can be adjusted in time according to the load conditions of the electric loader, so that the electric loader can maintain a stable driving state under different loads, thereby reducing the wear of the electric loader.

[0017] 1. This invention incorporates a tilt sensor in conjunction with an automatic load adjustment system, enabling it to automatically adjust the transmission's shift timing and gear ratio based on the vehicle's real-time load and driving conditions, eliminating the need for manual driver intervention. During hill climbing, the driver only needs to focus on driving, eliminating the need to consider shifting gears or adjusting the load. This reduces the driver's operational burden and makes driving easier and safer.

[0018] 2. The present invention can isolate the interior of the gearbox housing to a certain extent through the structural design of the rotating assembly through the first heat insulation plate and the second heat insulation plate, thereby preventing the temperature inside the gearbox housing from being too low and causing oil to agglomerate. On the other hand, when the electric loader is climbing a slope, the engine needs to output a large torque to overcome gravity, and the gearbox will be in a high-load working state accordingly. At this time, the friction between the components inside the gearbox will increase, thereby generating more heat, causing the temperature of the gearbox to rise, and heat dissipation is required. At this time, the driving block is driven to drive the driving slot to move, and the driving slot drives the rotating small rod to move, so that the rotating small rod rotates with the rotating disk as the axis, the rotating small rod drives the rotating disk to rotate, the rotating disk drives the rotating long rod to rotate, and the rotating long rod drives the first heat insulation plate to rotate in the opposite direction, so that the first heat insulation plate no longer blocks the heat dissipation pipe, thereby improving the heat dissipation performance inside the gearbox housing, avoiding excessive temperature inside the gearbox housing causing wear on components, and increasing the service life of the gearbox;

[0019] 3. Through the structural design of the auxiliary mechanism, the present invention can enable the connecting rod to drive the torsion housing to move when the continuously variable transmission is adjusted, and the torsion housing drives the separation plate to move, so that the separation plate can separate the oil stains on the surface of the inclined bottom plate, preventing the oil stains from remaining on the surface of the inclined bottom plate due to the low temperature, causing a safety hazard.

[0032] Example 1

[0033] The present invention proposes a gearbox with adaptive load adjustment for an electric loader. By arranging a tilt sensor 12 in the gearbox, the gearbox can adaptively adjust the load when the electric loader climbs a slope, eliminating the need for the driver to repeatedly and frequently perform manual adjustments, thereby reducing the driving burden and improving driving safety.

[0034] In this embodiment, the structure of the gearbox is as follows: Figures 1 to 6 As shown, Figures 2 to 6 Only part of the gearbox is shown, mainly showing the part related to the present invention. The gearbox of the present invention includes a gearbox housing 1, a transmission rod 2, a first bevel gear 3, a second bevel gear 4 and a continuously variable transmission, such as Figures 1 to 3As shown, a transmission rod 2 is rotatably installed inside the gearbox housing 1, and a first bevel gear 3 is fixedly installed on one end of the transmission rod 2. A second bevel gear 4 is meshed and installed on one side of the first bevel gear 3, and a continuously variable transmission is fixedly installed on one end of the second bevel gear 4. The continuously variable transmission includes a first speed-changing cone 5, an outer wall of the first speed-changing cone 5 is sleeved with a transmission belt 6, and the other end of the transmission belt 6 is sleeved with a second speed-changing cone 7. An adjusting block (not shown in the figure) is sleeved on the outer wall of the transmission belt 6, and a first moving block 8 is fixedly installed on the bottom end of the adjusting block. Drive assemblies are provided on both sides of the first moving block 8, and a screw rod 9 is threadedly installed on the inner wall of the first moving block 8. A motor 10 is provided at one end of the screw rod 9, and the motor 10 is connected to an external power supply through a wire. An output rod 11 is fixedly installed on one end of the second speed-changing cone 7, as shown in FIG. Figures 1 to 3 As shown, a tilt sensor 12 is fixedly installed on the inner wall of the gearbox housing 1. When the gearbox in the prior art is used by the electric loader to climb a slope, the driver needs to have high driving skills and experience, and frequent gear shifting and adjustment are required when climbing a slope. The operation is relatively complicated, which can easily distract the driver's attention and increase the difficulty and risk of driving. After the gearbox adopts the tilt sensor 12 of the present invention, the automatic load adjustment system can automatically adjust the gear shifting timing and transmission ratio of the gearbox according to the real-time load condition and driving state of the vehicle without manual intervention by the driver. During the climbing process, the tilt sensor 12 senses the electric loader The carrier is in a tilted state and sends a signal to the engine based on the degree of tilt, causing the engine to adaptively reduce its output power. At the same time, a signal is sent to start the motor 10, causing the motor 10 to rotate the screw rod 9, which in turn drives the first moving block 8 to move, which in turn drives the adjustment block to move, which in turn drives the transmission belt 6 to move, thereby changing the transmission ratio between the first speed-changing cone 5 and the second speed-changing cone 7. The driver only needs to focus on driving operations and does not need to be distracted by considering when to shift gears or adjust the load, which reduces the driver's operating burden and makes driving easier and safer. The model of the motor 10 is LW100.

[0035] In this embodiment, if Figures 1 to 4As shown, the rotating assembly includes a driving groove 19 opened on the inner side of the driving block 18, and a pair of driving grooves 19 are opened on the inner side of each driving block 18. The inner walls of the driving grooves 19 are all in contact with a rotating small rod 20, and the outer walls of the rotating small rod 20 are fixedly installed with a rotating disk 21. The bottom end of one of the rotating disks 21 is fixedly installed with a rotating long rod 22, and one side of the rotating long rod 22 is fixedly installed with a first heat insulation plate 23. The bottom end of the other rotating disk 21 is sleeved on the outer wall of the rotating long rod 22, and one side of the rotating long rod 22 is fixedly installed with a second heat insulation plate 24. The first heat insulation plate 23 and the second heat insulation plate 24 are both rotatably installed on the inner wall of the heat dissipation pipe 25, and the heat dissipation pipe 25 is fixedly installed on both sides of the gearbox housing 1. With this design, on the one hand, when the electric loader is operating normally, the first heat insulation plate 23 and the second heat insulation plate 24 can be used to isolate the inside of the gearbox housing 1 to a certain extent, thereby avoiding the gearbox housing 1 The phenomenon of oil agglomeration is caused by the low internal temperature. On the other hand, when the electric loader climbs a slope, the engine needs to output a large torque to overcome gravity, and the gearbox will be in a high-load working state accordingly. At this time, the friction between the components inside the gearbox will increase, thereby generating more heat, causing the gearbox temperature to rise, and heat dissipation is required. At this time, the driving block 18 is driven, so that the driving block 18 drives the driving slot 19 to move, and the driving slot 19 drives the rotating rod 20 to move, so that the rotating rod 20 rotates with the rotating disk 21 as the axis, and the rotating rod 20 drives the rotating disk 21 to rotate, and the rotating disk 21 drives the rotating long rod 22 to rotate, and the rotating long rod 22 drives the first heat insulation board 23 to rotate in opposite directions, so that the first heat insulation board 23 no longer blocks the heat dissipation pipe 25, thereby improving the heat dissipation performance in the gearbox housing 1, avoiding excessive temperature in the gearbox housing 1 to cause wear on components, and improving the service life of the gearbox.

[0036] Furthermore, in this embodiment, Figure 2 and Figure 3 As shown, the driving assembly includes a connecting rod 13 arranged on both sides of the first moving block 8, the outer wall of the connecting rod 13 is provided with an auxiliary mechanism, one end of the connecting rod 13 is fixedly installed with a second moving block 14, one side of the second moving block 14 is fixedly installed with a guide block 15, the outer wall of the guide block 15 is provided with a first guide rail, the first guide rail is fixedly installed on the inner wall of the gearbox housing 1, the top of the second moving block 14 is fixedly installed with a third moving block 16, one side of the third moving block 16 is slidably installed with a fourth moving block 17, one end of the fourth moving block 17 is fixedly installed with a driving block 18, and the inner side of the driving block 18 is provided with a rotating assembly. With this design, when the gearbox is load adjusted, the first moving block 8 drives the connecting rod 13 to move, the connecting rod 13 drives the second moving block 14 and the guide block 15 to move along the first guide rail, the second moving block 14 drives the third moving block 16 to move, the third moving block 16 drives the fourth moving block 17 to move, and the fourth moving block 17 drives the driving block 18 to move, thereby driving the rotating assembly to operate.

[0037] Furthermore, in this embodiment, Figure 3 and Figure 4 As shown, a connecting bar 26 is provided between the third moving block 16 and the fourth moving block 17, one end of the connecting bar 26 is fixedly mounted on one end of the third moving block 16, and a sliding block 27 is fixedly mounted on the other end of the connecting bar 26. The sliding blocks 27 are slidably mounted on the inner wall of the sliding groove 28, and the sliding grooves 28 are opened on both sides of the fourth moving block 17. A guide shell 29 is fixedly mounted on one side of the sliding groove 28. In this design, when the third moving block 16 moves toward the direction close to the fourth moving block 17, the third moving block 16 first drives the connecting bar 26 to move, and the connecting bar 26 drives the sliding block 2 7 moves, so that the sliding block 27 slides along the inner wall of the sliding groove 28, thereby providing a guiding effect on the movement of the third moving block 16, making the movement of the third moving block 16 more stable and smooth. At the same time, the continuously variable transmission can drive the third moving block 16 to move a certain distance and then abut against the fourth moving block 17, so that when the load is adjusted to a relatively small extent, the driving component will not drive the rotating component to operate, thereby preventing the rotating component from still operating when the load of the electric loader is relatively small, thereby improving the heat dissipation performance, resulting in a low temperature in the transmission housing 1, and affecting the operation of the transmission, thereby improving the stability and reliability of the rotating component.

[0038] Example 2

[0039] See also Figure 5 and Figure 6 As shown, compared with Example 1, as another embodiment of the present invention, an inclined bottom plate 30 is fixedly installed at the bottom end of the gearbox housing 1, and an oil screw plug 31 is fixedly installed on one side of the gearbox housing 1. The inclined bottom plate 30 is inclined downward in the direction close to the oil screw plug 31. This design allows the oil generated in the gearbox housing 1 to move to the lowest end of the inclined bottom plate 30 under the action of gravity, and can be discharged from the gearbox housing 1 through the oil screw plug 31, preventing the oil from accumulating to a certain extent and causing a fire if it encounters high temperature, posing a serious safety threat to the vehicle and personnel.

[0040] In this embodiment, if Figure 5 and Figure 6 As shown, the auxiliary mechanism includes a torsion shell 32 arranged on the outer wall of the connecting rod 13, a torsion spring is arranged inside the torsion shell 32, and a separation plate 33 is fixedly installed on the bottom end of the torsion shell 32. With this design, when the continuously variable transmission is adjusted, the connecting rod 13 drives the torsion shell 32 to move, and the torsion shell 32 drives the separation plate 33 to move, so that the separation plate 33 separates the oil and dirt on the surface of the inclined bottom plate 30, preventing the oil and dirt from remaining on the surface of the inclined bottom plate 30 due to the low temperature, causing a safety hazard.

[0041] Furthermore, in this embodiment, the separation plate 33 is configured to have one side convex and the other side concave. This design allows the concave side of the separation plate 33 to penetrate into the recessed areas on the surface of the object, separating the oil from these areas, thereby improving the separation effect. At the same time, the concave side can better fit the surface of the object, reducing the gap between the separation plate 33 and the surface of the object, avoiding oil residue between the separation plate 33 and the surface of the object, and further reducing the wear of the separation plate 33. In addition, the convex side helps to guide the movement direction of the separation plate 33 so that it better fits the surface of the object, especially when separating solidified oil, the convex side can help the separation plate 33 to separate in the correct direction, thereby improving the accuracy and effect of the separation.

[0042] Furthermore, in the present embodiment, an abutment block 34 is fixedly mounted on one end of the torsion housing 32, and the abutment blocks 34 are all in abutment with the abutment bars 35, and the abutment bars 35 are all fixedly mounted on the inner wall of the gearbox housing 1. With this design, the abutment blocks 34 and the abutment bars 35 cooperate with the torsion spring provided inside the torsion housing 32, so that when the electric loader is operating normally, the torsion spring drives the torsion housing 32 to rotate, and the torsion housing 32 drives the separation plate 33 and the abutment block 34 to rotate, so that the abutment block 34 abuts with the abutment bar 35. At this time, the separation plate 33 is lifted upward, and a gap is generated between it and the surface of the inclined bottom plate 30, so that oil and dirt can pass through the gap to the outermost part of the inclined bottom plate 30 The low-end flow prevents the separation plate 33 from abutting the surface of the inclined bottom plate 30 to hinder the movement of oil and dirt. In addition, when the first moving block 8 drives the torsion shell 32 to move through the connecting rod 13, the torsion shell 32 drives the abutment block 34 to move, so that the abutment block 34 abuts against the abutment bar 35, so that the abutment bar 35 drives the abutment block 34 to rotate, and the abutment block 34 drives the torsion shell 32 to rotate, and the torsion shell 32 drives the separation plate 33 to rotate, so that the separation plate 33 abuts against the surface of the inclined bottom plate 30. At the same time, the torsion spring arranged in the torsion shell 32 is tightly abutted against the bottom end of the abutment bar 35 through the torsion shell 32, further enhancing the separation effect of the separation plate 33.
