Description

Technical Field

[0001] The present invention relates to the technical field of single rocker wheels, and more specifically to a gear motor on a single rocker wheel. Background Art

[0002] When traditional electric vehicles are dealing with uphill sections, their traction is greatly limited due to the effect of their own gravity. In order to overcome this gravity obstacle, electric vehicles usually need to increase the current output to the motor to increase the torque of the motor, thereby ensuring that the electric vehicle can climb smoothly. However, this solution is not without cost. Increasing the current output means that the battery needs to release more energy in a short period of time, which will not only cause the battery power to drop rapidly, but may also have an adverse effect on the chemical structure inside the battery. In the long run, this high-load usage will accelerate the aging process of the battery, shorten its service life, and may even cause battery failure or safety problems.

[0003] In addition, when electric vehicles are driving, they will inevitably encounter bumpy roads. In order to pass these potholes smoothly, electric vehicles need to constantly adjust their posture and power output, which also means that the battery needs to frequently output large currents to the motor to cope with sudden power demands. This frequent current fluctuation will cause additional burden on the battery. More importantly, the frequent output of large currents by the battery will also cause rapid consumption of the electric vehicle's power. For electric vehicles that rely on battery power, the rapid decline in power will directly limit their driving distance and endurance, which will not only affect users' travel plans, but may also bring unnecessary charging troubles and increased costs. Therefore, for traditional electric vehicles, how to reduce the load and loss of the battery while ensuring power output has become a technical problem that needs to be solved urgently.

[0004] In view of this, in view of the above-mentioned deficiencies, the present invention improves and optimizes the output of electric vehicles in the prior art and develops a single rocker arm wheel gear motor. Summary of the invention

DETAILED DESCRIPTION

[0067] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0068] See also Figures 1 to 12 A single rocker wheel gear motor includes a driving assembly 1, which is composed of a driving body 101 and a driving shaft 102; a gearbox cover 19, which is installed at the output end of the driving assembly 1, and one end of the driving shaft 102 extends to the inside of the gearbox cover 19; a first gear 2, which is installed at one end of the driving shaft 102, and the first gear 2 is located in the gearbox cover 19; a second gear 4, which is meshed with the first gear 2, and the diameter of the second gear 4 is greater than the diameter of the first gear 2; a third gear 5, which is fixedly installed on one side of the second gear 4, and the third gear The diameter of the wheel 5 is smaller than that of the second gear 4; the fourth gear 6, the fourth gear 6 is meshed and connected with the third gear 5, and the diameter of the fourth gear 6 is larger than the diameter of the third gear 5, and the fourth gear 6 is arranged concentrically with the first gear 2; the stabilizing component 3, the stabilizing component 3 is installed between the first gear 2 and the fourth gear 6, and the stabilizing component 3 is used to stabilize the concentric axis of the fourth gear 6 and the first gear 2; the output bearing 7, the output bearing 7 is installed at the center position of the fourth gear 6, and the output bearing 7 moves through the gear box cover 19 and extends to the outside; the hub assembly, the hub assembly is installed on the output bearing 7 outside the gear box cover 19.

[0069] When in use, by turning on the driving component 1, the driving component 1 is a motor. When the driving component 1 is turned on, the driving shaft 102 will rotate, and the driving shaft 102 will drive the first gear 2 to rotate when rotating, and the first gear 2 will drive the second gear 4 to rotate when rotating, because the first gear 2 and the second gear 4 are small gears driving large gears to rotate, thus achieving a first reduction in the speed of the output of the driving component 1 and increasing the torque, the second gear 4 will synchronously drive the third gear 5 to rotate when rotating, and the third gear 5 will drive the fourth gear 6 to rotate when rotating, because the third gear 5 and the fourth gear 6 are small gears driving large gears to rotate, thus achieving a second reduction in the speed of the output of the driving component 1 and increasing the torque, the present invention achieves a second reduction in the speed of the output of the driving component 1 and increasing the torque by twice The driving component 1 reduces the rotation speed and increases the torque. In this way, when the driving component 1 drives the wheel hub component to travel on the road, the overall torque of the wheel hub component is greatly improved, which enables the wheel hub component to easily pass through bumpy roads without increasing the input current of the driving component 1. This allows the battery to discharge smoothly and avoids increasing the input current of the driving component 1, which means that the battery's workload is more stable and reduces the risk of battery overheating, performance degradation, or even damage due to current mutations. This is beneficial to maintaining the battery's health and extending its service life. Since various road conditions can be smoothly passed without increasing the input current of the driving component 1, the present invention effectively reduces energy consumption. In scenarios such as electric vehicles that rely on battery power, it helps to extend the cruising range and reduce the charging frequency, thereby improving energy efficiency.

[0070] In addition, the fourth gear 6 of the present invention is concentrically arranged with the first gear 2 and the hub assembly. Such a concentric arrangement makes the entire transmission system more compact, helps to save space, and facilitates hiding the motor inside the hub. The compact structure also helps to reduce the overall weight of the equipment and improve the flexibility and mobility of the equipment. The concentric arrangement can ensure the accuracy of the transmission system. The high-precision transmission system helps to improve the overall performance and efficiency of the equipment.

[0071] In some embodiments, a protective shell 18 is installed on the outside of the drive assembly 1; a heat sink 20 is installed on the outside of the protective shell 18, and the heat sink 20 is arranged in multiple groups, and the heat sink 20 is hollow; a connecting pipe 21 is installed between the heat sinks 20, and the interiors of the multiple groups of heat sinks 20 are interconnected through the connecting pipe 21; a guide pipe 23 is installed on one group of heat sinks 20, and the outer shell of the gearbox cover 19 is convexly designed corresponding to the third gear 5. The guide pipe 23 has one end away from the heat sink 20 and is connected to the protrusion of the gearbox cover 19; the paddle blades 22 have an annular hole extending through the second gear 4, and both ends of the paddle blades 22 are fixedly connected to the inner wall of the annular hole. The paddle blades 22 are arranged in multiple groups, and the multiple groups of paddle blades 22 are distributed in an annular shape; the delivery pipe 24 has one end connected to one group of heat sinks 20; the drain pipe 27 is connected to the delivery pipe 24, and the interior of the drain pipe 27 is connected to the interior of the gearbox cover 19.

[0072] Because the gear structures in the gearbox cover 19 are arranged closely to each other, the heat dissipation effect is poor. However, when the electric vehicle is running, the second gear 4 will rotate. Due to the connection or integrated design between the second gear 4 and the paddle blade 22, the paddle blade 22 will rotate synchronously with the second gear 4. The rotating paddle blade 22 pushes the lubricating oil in the gearbox cover 19, so that the lubricating oil flows to the protrusion of the gearbox cover 19. The design of the protrusion helps to guide the lubricating oil into the guide pipe 23, and the lubricating oil flows into the inside of the heat sink 20 through the guide pipe 23, and then is distributed to each heat sink 20 through the connecting pipe 21. After flowing inside the heat sink 20, the lubricating oil flows into the delivery pipe 24, and finally returns to the gearbox cover 19 through the drain pipe 27, completing a cycle. During the driving process of the electric vehicle, the external airflow will pass through the heat sink 20, increase the contact area between the heat sink 20 and the air, and improve the heat dissipation efficiency. At the same time, when the flowing lubricating oil passes through the heat sink 20, the heat sink 20 not only helps the motor to dissipate heat, but also helps the lubricating oil to cool down. The cooled lubricating oil enters the gearbox cover 19 again to cool the inside of the gearbox cover 19, reducing wear and failure caused by high temperature, thereby improving the stability and durability of the entire system. By closely combining the heat dissipation function with the gear structure, it not only meets the heat dissipation requirements, but also maintains the compactness of the structure, thereby improving the overall performance of the electric vehicle.

[0073] In some embodiments, a processor cover 25, the processor cover 25 is installed at one end of the delivery pipe 24 away from the heat sink 20, and the delivery pipe 24 is connected to the upper half of the processor cover 25, and a drain pipe 27 is connected to the lower half of the processor cover 25; a filter screen cylinder 26, the filter screen cylinder 26 is arranged inside the processor cover 25, and the filter screen cylinder 26 is arranged in the lower half of the processor cover 25; a permanent magnet plate 37, the permanent magnet plate 37 is installed at the inner bottom position of the processor cover 25, a sealing plate 30, the sealing plate 30 is fixedly connected to the inner wall of the processor cover 25, and the sealing plate 30 is located above the filter screen cylinder 26; a lifting column 31, the lifting column 31 movably passes through the upper and lower ends of the sealing plate 30; a drain port 34, a drain The liquid port 34 is provided at the lower end surface of the lifting column 31; the support rod 35, the support rod 35 is fixedly connected to the side surface of the lifting column 31 near the lower end; the brush ring 36, the inner wall of the brush ring 36 is fixedly connected to the end of the support rod 35 away from the lifting column 31, and the bristles of the brush ring 36 are in contact with the inner wall of the filter cylinder 26; the spring 32, the spring 32 is sleeved on the outside of the lifting column 31, and the spring 32 is located above the sealing plate 30; the blocking disk 33, the blocking disk 33 is fixedly connected to the upper end of the lifting column 31, and the blocking disk 33 is made of permanent magnetic material; the electromagnet 38, the electromagnet 38 is installed at the upper end of the processor cover 25, and the electromagnet 38 is energized to push the blocking disk 33 to move downward through the magnetic repulsion force.

[0074] By adopting the above technical solution, the lubricating oil in the delivery pipe 24 will be discharged into the processor cover 25, and flow into the filter screen cylinder 26 through the drain port 34, filtered by the filter screen cylinder 26, and then discharged into the gear box cover 19 through the drain pipe 27. Because the wear between the gears will produce iron filings, these iron filings flow into the gaps of the gear meshing with the lubricating oil, which will accelerate the wear of the gears. The present invention removes the iron filings in the lubricating oil by filtering the filter screen cylinder 26, which slows down the wear between the gears to a certain extent. During the driving of the electric vehicle, the electromagnet 38 can be intermittently energized. When the electromagnet 38 is energized, the magnetic repulsion of the electromagnet 38 will push the blocking plate 33 to move downward, and the blocking plate 33 will drive the lifting column 31 to move synchronously when moving downward, so that the lifting column 31 can be lifted. When the lowering column 31 moves downward, the discharge port 34 will move downward to the bottom of the sealing plate 30, and the lifting column 31 will seal the opening of the sealing plate 30. At this time, the lubricating oil can no longer flow from the top of the sealing plate 30 to the bottom of the sealing plate 30. When the lifting column 31 moves downward, it will drive the support rod 35 and the brush ring 36 to move downward synchronously. When the brush ring 36 moves downward, it will clean the iron filings on the inner wall of the filter screen cylinder 26, because at this time the lubricating oil no longer passes through the filter screen cylinder 26. In the absence of lubricating oil impacting the filter screen cylinder 26, the cleaning effect is better. The iron filings cleaned by the brush ring 36 are also easy to fall down with their own gravity. A permanent magnet plate 37 is provided below the filter screen cylinder 26. The permanent magnet plate 37 can lock the iron filings at the bottom of the filter screen cylinder 26 through magnetic force to prevent the lubricating oil from floating up again and clogging the filter screen cylinder 26 when circulating. When the blocking plate 33 moves downward, it will also squeeze the spring 32. When the electromagnet 38 is powered off, the blocking plate 33 will no longer be subjected to a magnetic repulsive force. The previously compressed spring 32 will push the blocking plate 33 to move upward. When the blocking plate 33 moves upward, it will drive the lifting column 31 to move synchronously. Finally, the drain port 34 will move to the opening of the sealing plate 30 and open the opening of the sealing plate 30. At this time, the lubricating oil can pass through the drain port 34 and the opening of the sealing plate 30 and flow into the filter screen cylinder 26 for circulation filtration.

[0075] In some embodiments, the first jet tube 28 and the second jet tube 29 are both connected to the end of the drain pipe 27 away from the processor cover 25, and the ends of the first jet tube 28 and the second jet tube 29 away from the drain pipe 27 extend to the interior of the gear box cover 19, and the opening of the first jet tube 28 faces the meshing position of the third gear 5 and the fourth gear 6, and the opening of the second jet tube 29 faces the meshing position of the first gear 2 and the second gear 4.

[0076] The lubricating oil discharged from the drain pipe 27 of the present invention will flow out from the openings of the first jet tube 28 and the second jet tube 29. When the motor rotates at high speed, the circulating lubricating oil will flow rapidly. At this time, the rapidly flowing lubricating oil will be ejected from the openings of the first jet tube 28 and the second jet tube 29, respectively toward the meshing position of the third gear 5 and the fourth gear 6 and the meshing position of the first gear 2 and the second gear 4. By impacting the meshing position of the gears with the lubricating oil, iron filings at the meshing position of the gears can be quickly removed, greatly reducing the wear of the gears during meshing transmission, and facilitating the iron filings at the meshing position of the gears to flow with the lubricating oil to the filter screen cylinder 26 for filtering treatment. In addition, when the lifting column 31 blocks the opening of the sealing plate 30, the rotation of the paddle blades 22 will continuously transport lubricating oil into the processor cover 25, causing the oil pressure in the upper half of the processor cover 25 to increase. When the lifting column 31 moves up to open the opening of the sealing plate 30, the lubricating oil in the upper half of the processor cover 25 will instantly release pressure and flow downward. Finally, the openings of the first jet tube 28 and the second jet tube 29 will instantly spray a high jet of lubricating oil to impact the gear meshing. By intermittently ejecting a high jet of lubricating oil to the gear meshing, the effect of removing iron filings at the gear meshing can be improved. The injection of lubricating oil can not only remove iron filings, but also reduce the friction and wear of the gears during meshing transmission, thereby extending the service life of the gears.

[0077] In some embodiments, the deflector sheets 39 are fixedly connected to the inner wall of the delivery tube 24, and are distributed in multiple groups in a ring shape. The deflector sheets 39 are made of elastic material. When the deflector sheets 39 are in a free state, adjacent deflector sheets 39 are close to each other, so that the connection between the delivery tube 24 and the processor cover 25 is in a closed state, and multiple groups of deflector sheets 39 are inclined toward the processor cover 25.

[0078] When the lubricating oil circulates, it will break open the multiple groups of reversal plates 39 to ensure the circulation of the lubricating oil. If the lubricating oil flows in the opposite direction, for example, when the electric vehicle is reversing, the paddle blades 22 rotate in the opposite direction, and the reverse-flowing lubricating oil impacts the reversal plates 39. Because the multiple groups of reversal plates 39 are close to each other and the reversal plates 39 are tilted toward the processor cover 25, the lubricating oil cannot flow in the opposite direction. The multiple groups of reversal plates 39 act as a one-way valve. This design can prevent the iron filings in the processor cover 25 from flowing back.

[0079] In some embodiments, the processor cover 25 is composed of an upper cover 251 and a lower cover 252, the upper cover 251 and the lower cover 252 are threadedly connected, the upper cover 251 is arranged above the lower cover 252, the outer circular surface of the filter screen cylinder 26 is connected to an outer ring near the upper end, and a barrier ring is arranged at the lower end of the outer ring, and the barrier ring is fixedly connected to the inner wall of the lower cover 252.

[0080] If the filter screen cartridge 26 needs to be replaced, one only needs to unscrew the upper cover 251 and the lower cover 252, take out the old filter screen cartridge 26, put the new filter screen cartridge 26 into the lower cover 252, and tighten the upper cover 251 and the lower cover 252 again. The operation is simple and convenient.

[0081] In some embodiments, the centering assembly 3 also includes a crescent plate 301, which is arranged between the first gear 2 and the fourth gear 6. A threaded hole is opened on the crescent plate 301, and the crescent plate 301 is fixedly connected to the gear box cover 19 by screws passing through the threaded hole; a stabilizing sleeve 302, which is fixedly installed on the adjacent surface of the crescent plate 301 and the first gear 2, and the first gear 2 is hidden in the stabilizing sleeve 302, and one side of the stabilizing sleeve 302 is opened with an opening for the first gear 2 to mesh with the second gear 4; a plug-in shaft 303, which is fixedly connected to a side of the crescent plate 301 away from the stabilizing sleeve 302, and the output bearing 7 is hollow in design, and the end of the plug-in shaft 303 away from the crescent plate 301 is plugged into the hollow part of the output bearing 7; a bearing 8, which is plugged into the outside of the plug-in shaft 303, and the outer wall of the bearing 8 is in contact with the hollow inner wall of the output bearing 7.

[0082] In the present invention, the fourth gear 6, the first gear 2 and the hub assembly are concentrically arranged to ensure the accuracy and stability of the transmission. The crescent plate 301 is firmly fixed inside the gearbox cover 19 by screws, providing stable support for subsequent assembly. The first gear 2 is hidden in the stabilizing sleeve 302, which not only protects the first gear 2, but also ensures the stability of the first gear 2 during the transmission process through its structural characteristics. The output bearing 7 is directly inserted into the plug-in shaft 303. This design simplifies the assembly process, making the assembly of the fourth gear 6 and the third gear 5 easier. At the same time, the plug-in shaft 303 also provides a stable support for the output bearing 7, avoiding the eccentric rotation during the rotation process. The setting of the bearing 8 further reduces the friction between the output bearing 7 and the plug-in shaft 303, so that the output bearing 7 can rotate more smoothly. By ensuring that the fourth gear 6, the first gear 2 and the hub assembly are concentrically arranged, the accuracy and stability of the transmission are improved. This improvement helps to reduce errors and vibrations during the transmission process, thereby improving the driving performance and riding comfort of the vehicle. By simplifying the assembly process of the gears inside the gearbox cover 19, the production cost can be reduced and the production efficiency can be improved.

[0083] In some embodiments, the wheel hub assembly includes a brake disc 13 and an outer gear ring 12, wherein the outer gear ring 12 is installed at the center of the brake disc 13; an inner gear ring 10, wherein the inner gear ring 10 is fixedly connected to the outer circumferential surface of the output bearing 7, and the outer circumferential surface of the inner gear ring 10 can be engaged with the inner wall of the outer gear ring 12; a limiting ring 9, wherein the limiting ring 9 is fixedly connected to the outer circumferential surface of the output bearing 7, and the limiting ring 9 is located between the fourth gear 6 and the inner gear ring 10, and the limiting ring 9 is used to block the movement of the brake disc 13; a wheel hub 14, The wheel hub 14 is inserted into the output bearing 7; the bolt hole 16 is provided on the brake disc 13; the bolt 15 is inserted into the bolt hole 16, one end of the bolt 15 passes through the wheel hub 14 and extends to the outside; the nut 17 is threadedly connected to the portion of the bolt 15 passing through the wheel hub 14; the fastening cap 11, one end of the output bearing 7 passes through the wheel hub 14 and is threadedly connected to the fastening cap 11, and the threaded fixing direction of the fastening cap 11 and the output bearing 7 is the same as the forward direction of the wheel hub 14.

[0084] To fix the wheel hub 14 and the brake disc 13, the bolt 15 is passed through the bolt hole 16 and the bolt hole on the wheel hub 14, and then the nut 17 is tightened to achieve the fixation between the wheel hub 14 and the brake disc 13. The output bearing 7 of the present invention passes through the center of the brake disc 13 and the center of the wheel hub 14. At this time, the outer gear ring 12 will be stuck on the inner gear ring 10. At this time, the fastening cap 11 is tightened on the thread of the output bearing 7 to achieve the fixation of the wheel hub 14 and the brake disc 13. When the wheel hub 14 needs to be disassembled, only the fastening cap 11 needs to be screwed off to disassemble the wheel hub 14 and the brake disc 13. The operation is simple, convenient and practical. In addition, the threaded fixing direction of the fastening cap 11 and the output bearing 7 is the same as the forward direction of the wheel hub 14. When the wheel hub 14 is moving forward, the threaded connection between the fastening cap 11 and the output bearing 7 will be subjected to a preload force in the same direction as the driving direction. This preload force helps to maintain the stability of the connection. In the present invention, a rocker frame 40 is installed outside the protective shell 18 to facilitate installation of the wheel hub 14 with power output on the electric vehicle, thereby forming a modular assembly.
