Description

Technical Field

[0001] This invention relates to the field of motor cooling technology, specifically to an integrated dual-drive coaxial gear motor device based on a continuously variable transmission. Background Technology

[0002] Continuously variable transmissions (CVTs) use a drive belt and variable-diameter primary and driven pulleys to transmit power, allowing for continuous changes in the transmission ratio and thus achieving optimal matching between the transmission system and engine operating conditions. Common CVTs include hydraulic-mechanical CVTs and metal belt CVTs. In their use, a dual-shaft motor is required to drive the CVT. Within the application of CVTs, there are integrated dual-drive coaxial gear motor drive systems.

[0003] Gear motors utilize coaxial dual shafts to connect to continuously variable transmissions (CVTs) or other power sources. During operation, high motor temperatures are a concern; the motor must be shut down if the surface temperature exceeds 80 degrees Celsius. When connecting the motor bearings to the CVT, grease needs to be applied. Some greases can reach temperatures as high as 85 degrees Celsius, which can easily melt the grease, posing an extreme danger. Therefore, the motor surface temperature must be controlled below 50 degrees Celsius, reaching a maximum of 60-65 degrees Celsius in summer. Traditional solutions involve using air coolers for auxiliary cooling, but this method suffers from problems such as untimely cooling, excessive energy consumption, and incomplete cooling coverage. Therefore, we propose an integrated dual-drive coaxial gear motor device based on a CVT. Summary of the Invention

The surface of the thermal induction base is fixedly connected to the surface of the drive disc. A memory spring is fixedly connected internally to the thermal induction base.

[0008] Preferably, the output shaft auxiliary cooling device includes a cooling oil tank and an automatic feeding device. The end of the cooling oil tank is fixedly connected to the surface of the motor body. An extrusion plate is elastically connected inside the cooling oil tank by a spring.

[0013] As can be seen from the above technical solutions, the integrated dual-drive coaxial gear motor device based on a continuously variable transmission provided in the embodiments of this specification has at least the following beneficial effects:

[0014] (1) The present invention uses an automatic overall cooling device to drive the fan plate to tilt and fan when the motor is at high temperature, thereby achieving the effect of tilting and driving the air during the revolution of the fan plate, improving the air cooling effect, and then achieving the purpose of rapid cooling. The fan plate is driven to rotate and air cool by the force of the output shaft rotation of the motor during operation, achieving timely cooling while achieving the effect of one shaft for multiple uses.

The intermittent up and down movement of the first valve rod can achieve the effect of small amount and intermittent oil intake. While ensuring the oil cooling function, it avoids excessive waste of cooling oil. Only at high temperature can the second valve rod, which allows oil to flow, be given way, to further improve the effectiveness of oil cooling and avoid the problem of rapid consumption and waste of cooling oil caused by ineffective oil cooling.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] Please see Figures 1-5 As shown, an integrated dual-drive coaxial gear motor device based on a continuously variable transmission includes a motor body 1, with a support base 2 fixedly connected to the surface of the motor body 1; an automatic overall cooling device 3, which is located at the end of the motor body 1, for overall air cooling of the surface of the dual-drive coaxial gear motor under high temperature; and an output shaft auxiliary cooling device 4, which is located on the surface of the motor body 1, for oil cooling of the motor output shaft, thereby achieving cooling of the motor surface and the output shaft respectively.

[0029] In this embodiment, the automatic overall cooling device 3 includes an induction drive device 31 and a support bushing 32. The end of the support bushing 32 is fixedly connected to the end of the motor body 1. A drive ring 33 is rotatably connected to the surface of the support bushing 32. A drive slide rod 34 is slidably connected inside the drive ring 33. A limit ring 35 is slidably connected to the surface of the drive slide rod 34. A connecting base 36 is fixedly connected to the surface of the limit ring 35. A fan shaft 37 is rotatably connected inside the connecting base 36. When the surface temperature of the motor exceeds 65 degrees Celsius, the induction drive device 31 is connected to the output shaft of the motor in the working state to drive it. The drive ring 33 drives the connecting base 36 to rotate on the support bushing 32 through the drive slide rod 34. The connecting base 36 drives the fan blades on the multiple circularly arrayed fan shafts 37 to rotate and blow air onto the surface of the motor body 1, thereby achieving the effect of overall air cooling of the motor surface.

[0030] Furthermore, the drive ring 33 has a groove inside, the end of the drive slide rod 34 is fixedly connected to a limiting plate, the inside of the connecting base 36 is rotatably connected to the surface of the support bushing 32, the surface of the fan shaft 37 is fixedly connected to a fan plate, and the end of the fan shaft 37 is fixedly connected to a drive plate 38. The surface of the drive plate 38 is movably connected to the surface of the drive slide rod 34. Under the influence of rotational inertia and centrifugal force, the drive slide rod 34 slides in the groove on the ring relative to the original drive ring 33. During the sliding, the drive slide rod 34 is limited by the limiting ring 35 and squeezes the drive plate 38. After the drive plate 38 is subjected to force, it drives the fan plate to tilt and fan through the fan shaft 37, thereby achieving the effect of tilting and driving the air during the revolution of the fan plate, improving the air cooling effect, and thus achieving the purpose of rapid cooling.

[0031] Furthermore, the induction drive device 31 includes a connecting gear 311 and a thermal induction base 312. The connecting gear 311 is internally fixedly connected to the output shaft of the motor body 1. The surface of the thermal induction base 312 is fixedly connected to the surface of the drive disc 33. A memory spring 313 is fixedly connected inside the thermal induction base 312. A limit plate 314 is fixedly connected to the end of the memory spring 313. A passive block 315 is fixedly connected to the limit plate 314. The surfaces of the limit plate 314 and the passive block 315 are slidably connected to the inner wall of the thermal induction base 312. The memory spring utilizes the memory effect of the memory alloy. At low temperatures, the spring is in a contracted state. When the ambient temperature exceeds 65 degrees Celsius, the spring returns to its original position and stretches. That is, when the motor is in a high-temperature state, the memory spring 313 can immediately drive the passive block 315 on the limit plate 314 to move towards the axis of the motor body 1. After the movement, the output shaft of the motor body 1 will contact and drive the passive block 315 to rotate as a whole when it drives the connecting gear 311 to rotate. The passive block 315 drives the drive disc 33 to achieve the effect of air cooling on the surface of the motor. The force of the output shaft rotation when the motor is working drives the fan plate to rotate for air cooling, achieving timely cooling while achieving the effect of multiple uses of one shaft.

[0032] Example 2

[0033] Please see Figure 1 , Figure 6 and Figure 7 As shown, the output shaft auxiliary cooling device 4 includes a cooling oil tank 41 and an automatic feeding device 48. The end of the cooling oil tank 41 is fixedly connected to the surface of the motor body 1. The interior of the cooling oil tank 41 is elastically connected to a pressing plate 42 via a spring. A connecting seat 43 is fixedly connected to the surface of the cooling oil tank 41. A spray seat 45 is fixedly connected to the connecting seat 43 via a telescopic tube 44. A threaded rod 46 is fixedly connected to the spray seat 45. An adjusting disc 47 is threadedly connected to the surface of the threaded rod 46. The cooling oil in the cooling oil tank 41 is squeezed into the connecting seat 43 under high pressure by the pressing plate 42, and flows through the through groove in the first valve rod 483 and the through groove in the second valve rod 410 to the telescopic tube 44. Finally, it is sprayed out by the spray seat 45 aligned with the output shaft of the motor body 1 to achieve the effect of oil cooling of the motor output shaft. The height of the spray seat 45 on the threaded rod 46 can be adjusted by rotating the adjusting disc 47.

[0034] Furthermore, the end of the adjusting disc 47 is rotatably connected to the connecting seat 43. The automatic feeding device 48 includes an extrusion ring 481 and a first valve stem 483. The end of the extrusion ring 481 is rotatably connected to the end of the fan shaft 37. A cam 482 is fixedly connected to the surface of the extrusion ring 481. A connecting column 484 is fixedly connected to the end of the first valve stem 483. The extrusion ring 481 is driven to revolve by the rotating fan shaft 37. During the rotation of the extrusion ring 481, the cam 482 intermittently contacts and squeezes the first valve stem 483 to make it move up and down. The intermittent up and down movement of the first valve stem 483 can achieve the effect of small amount and intermittent oil intake, which ensures the oil cooling function while avoiding excessive waste of cooling oil.

[0035] Furthermore, the inner wall of the extrusion ring 481 is movably connected to the surface of the motor body 1, the inside of the first valve stem 483 is provided with a through groove, the surface of the first valve stem 483 is slidably connected to the inside of the connecting seat 43, and a spring is fixedly connected between the surface of the connecting column 484 and the surface of the connecting seat 43.

[0036] It is worth noting that an oil inlet pipe 49 is fixedly connected inside the cooling oil tank 41, and a second valve stem 410 is slidably connected inside the connecting seat 43. A memory spring 411 is fixedly connected between the end of the second valve stem 410 and the connecting seat 43. The memory spring 411 will move under the influence of high temperature. The force of the movement drives the second valve stem 410 to move upward. After the movement, the through groove inside the second valve stem 410 will connect with the through groove inside the connecting seat 43. At this time, the connecting seat 43 can communicate with the inside of the telescopic pipe 44 through the through groove inside the second valve stem 410. The memory spring 411 is sleeved on the second valve stem 410. Only under high temperature can the second valve stem 410, which is used for oil supply, can make way for the oil-carrying second valve stem 410, thereby improving the effectiveness of oil cooling and avoiding the problem of rapid consumption and waste of cooling oil due to ineffective oil cooling.

[0037] In addition, a waste oil tank 5 is fixedly connected to the support base 2, and an oil receiving plate 7 is fixedly connected to the waste oil tank 5 through a pipe 6. The oil receiving plate 7 is used to receive and guide the cooling oil at the output shaft of the motor body 1, so that the waste oil is collected in the waste oil tank 5, thereby avoiding the waste of cooling oil.

[0038] In the present invention, an integrated dual-drive coaxial gear motor device based on a continuously variable transmission (CVT) is used such that the two output shafts of the dual-axis gear motor are respectively connected to the CVT and other devices. The motor body 1 drives the devices connected to the two output shafts respectively, achieving a coaxial dual-drive effect. During motor use, if the surface of the motor is hot, when the temperature exceeds 65 degrees Celsius, the memory spring utilizes the memory effect of the memory alloy. At low temperatures, the spring is in a contracted state, and when the ambient temperature exceeds 65 degrees Celsius, the spring returns to its original position and stretches. That is, the memory spring 313 drives the passive block 315 on the limit plate 314 to move towards the axis of the motor body 1. After the movement, when the output shaft of the motor body 1 drives the connecting gear 311 to rotate, it will contact and drive the passive block 315 to rotate as a whole. The passive block 315 drives the drive ring 33 to rotate on the support bushing 32. At this time, the drive ring 33 drives the connecting base 36 to rotate as a whole through the drive slide rod 34 slidably connected inside it. The fan blades on the fan shaft 37, which are arranged in a circular array, rotate on the support bushing 32 and connect to the base 36, thereby rotating and blowing air onto the surface of the motor body 1. This achieves a comprehensive air cooling effect on the motor surface. At the same time, due to the influence of rotational inertia and centrifugal force, the drive slide rod 34 slides in the groove on the original drive disc 33. During the sliding, the drive slide rod 34 is limited by the limiting ring 35 and presses against the drive plate 38. After being subjected to force, the drive plate 38 drives the fan plate to tilt and fan through the fan shaft 37, thereby achieving the effect of tilting and driving air during the revolution of the fan plate, improving the air cooling effect, and thus achieving the purpose of rapid cooling.

[0039] During air cooling of the motor surface, the memory spring 411 moves due to the high temperature. The force of this movement drives the second valve stem 410 to move upward. After moving, the through groove inside the second valve stem 410 connects with the through groove inside the connecting seat 43. At this time, the connecting seat 43 can communicate with the inside of the telescopic tube 44 through the through groove inside the second valve stem 410. Simultaneously, the rotating fan shaft 37 drives the compression ring 481 to revolve. During the rotation of the compression ring 481, the cam 482 intermittently contacts and compresses the first valve stem 483, causing it to move up and down. After the first valve stem 483 moves upward, its internal through groove aligns and connects with the through groove inside the connecting seat 43. During this period, cooling... The cooling oil in the oil tank 41 is forced into the connecting seat 43 under high pressure by the elastic compression plate 42, and flows through the through groove in the first valve stem 483 and the through groove in the second valve stem 410 to the telescopic tube 44. Finally, it is sprayed out by the spray seat 45 at the output shaft of the motor body 1, achieving the effect of oil cooling the motor output shaft. The intermittent up and down movement of the first valve stem 483 can achieve the effect of small amount and intermittent oil intake, ensuring the oil cooling function while avoiding excessive waste of cooling oil. Combined with the second valve stem 410, which can only allow oil to flow at high temperature, the effectiveness of oil cooling is further improved, avoiding the problem of rapid consumption and waste of cooling oil due to ineffective oil cooling.
