Description

Technical Field

[0002] RV reducer is a reducer with a special transmission method. It has the characteristics of compact structure, smooth transmission and high efficiency. It is widely used in new energy vehicle power systems. With the rapid development of the new energy vehicle industry, electric drive systems have higher and higher requirements for high efficiency, compact design and stability. RV reducers have become an important part of electric vehicle (EV) drive systems due to their high torque transmission capability, excellent seismic resistance and efficient energy conversion.

[0003] There are many types of existing RV reducers, such as a steering transmission device for RV reducers disclosed in publication number CN118149059B. The device realizes the steering function by rotating the connecting gear, respectively meshing with the first gear shaft and the second gear shaft. However, when the connecting gear is driven to rotate and meshes with the second gear shaft, the connecting gear is stationary. When the connecting gear is in meshing contact with the second gear shaft, the tooth grooves are likely to be misaligned. When the tooth grooves are misaligned, the contact surface between the gears will slide, increasing the friction. This abnormal friction will cause wear on the gear surface, especially under high load or high speed conditions, the wear will be more serious, and will affect the efficiency and life of the entire transmission device.

The lower end of the oil inlet box 503 is fixedly installed with a nozzle, which passes through the second oil box 502 and extends into the interior thereof.

[0024] The working principle of the present invention is as follows: First, reversing: when the reducer 1 drives the output main shaft 301 to rotate, the output main shaft 301 drives the transmission shaft 303 to rotate through the meshing transmission gear pair 302, and the rotating transmission shaft 303 drives the long shaft 305, the first transmission gear 307 and the second transmission gear 308 to rotate together, and the rotating first transmission gear 307 drives the first driven gear 402 to rotate together, and the rotating first driven gear 402 drives the rotating main shaft 401 to move and rotate forward. At this time, the rotating long shaft 305 also drives the second transmission gear 308 to rotate, and the rotating second transmission gear 308 meshes with the pinion 405 to drive the second driven gear 403 to rotate on the outer wall of the rotating main shaft 401. When the rotating main shaft 401 is driven to rotate forward, the second driven gear 403 is driven to reverse on the outer wall of the rotating main shaft 401. At the same time, the second transmission gear 308 and the pinion 405 are always kept in a meshing state; When reversal is required, the screw 314 is driven to rotate by opening the rotary drive member 315. The rotating moving block 316 drives the rotating ring 309 and the rotating sleeve 304 to move through the rotating collar 310, so that the rotating sleeve 304 slides on the outer wall of the transmission shaft 303. When the rotating collar 310 is driven to move, the two connecting electrical contacts 311 provided are disconnected. The connecting electrical contacts 311 stop supplying power to the electromagnetic clutch 306, so that the clutch plate loses its magnetism and stops adsorbing the long shaft 305. The moving rotating sleeve 304 drives the long shaft 305 and the first transmission gear 307 and the second transmission gear 308 to move together. Because the width of the first transmission gear 307 is relatively large, it is still meshed with the first driven gear 402 when being driven to move. When the rotating sleeve 304 is driven to move, the snap ring 419 is driven to move together. The snap ring 419 contacts the rotating wheel 415 and squeezes the rotating wheel 415, the vertical plate 414 and the moving plate 413 to move in the fixed frame 412. The moving moving plate 413 compresses the second spring 416 and drives the moving rod 417 to squeeze the hydraulic oil set in the hydraulic chamber, so that the hydraulic pressure of the hydraulic oil is increased. The hydraulic oil with increased hydraulic pressure drives the disc 410 and the push rod 408 to slide in the inner groove 418 and compresses the third spring 420. The push rod 408 The conical head arranged at one end of the rod 404 contacts the top block 409 and squeezes the top block 409 to slide inside the short rod 404. The top block 409 slides into the second passive gear 403. After the electromagnetic clutch 306 stops adsorbing the outer wall of the long shaft 305, the force of the rotation of the long shaft 305 drives the pinion 405 and the second passive gear 403 to rotate through the second transmission gear 308. At this time, the rotating second passive gear 403 extends inside the top block 409 due to its sliding, and drives the rotating main shaft 401 to reverse during the rotation. When the rotating main shaft 401 is driven to rotate forward and reverse, the first transmission gear 307 and the second transmission gear 308 are respectively meshed with the first passive gear 402 and the second passive gear 403 for rotation. During the forward rotation, the first transmission gear 307 is meshed with the first passive gear 402 for transmission, and the second transmission gear 308 and the pinion 405 and the second passive gear 403 remain in a meshed and non-transmission state. During the reverse rotation, the second transmission gear 308 and the pinion 405 and the second passive gear 403 are meshed for transmission, and the first transmission gear 307 and the first passive gear 402 remain in a meshed and non-transmission state. This can effectively avoid the wear caused by the tooth grooves not being aligned when the gears are meshed, and avoid uneven meshing of the internal gears of the reducer, thereby making the power transmission more stable. Second, lubrication: During the gear meshing transmission process, lubricating oil is usually required for lubrication. The main function of lubricating oil is to form an oil film to reduce direct contact and friction between gears. However, if the amount of lubricating oil is insufficient, or the oil film is not formed completely due to oil degradation, the friction between gears will increase. The increased friction will not only accelerate the wear of the gears, but also generate more heat, leading to overheating. If the temperature is too high, the working efficiency of the reducer will decrease, because overheating may cause the softening and deformation of the gear material, or the viscosity of the lubricating oil will change, which will affect the lubrication effect, which will lead to a decrease in the energy efficiency of the entire drive power system, increase the burden on the battery of new energy vehicles, and affect the cruising range; By providing the first semiconductor chip 506, the second semiconductor chip 507 and the third semiconductor chip 508, when the lubricating oil between the gears in the first oil box 501 and the second oil box 502 is insufficient or the oil is degraded, the temperature in the first oil box 501 and the second oil box 502 will rise, and the first semiconductor chip 506 and the second semiconductor chip 507 provided in the first oil box 501 and the second oil box 502 will be heated by the increased temperature. Through the thermoelectric effect, the first semiconductor chip 506 and the second semiconductor chip 507 will form a temperature difference with the third semiconductor chip 508 when they are heated. The temperature difference formed will generate voltage in the series circuit, and the relay 509 will sense the generated voltage and control the external power supply to transmit voltage to the rotating motor 510, driving the rotating motor 510 to rotate. The rotating rotating motor 510 will drive the auger rotating shaft 512 to rotate in the delivery barrel 511, and then turn on the external oil pump to deliver part of the lubricating oil to the oil inlet box 503 through the connecting port 514. Part of the hydraulic oil entering the oil inlet box 503 will be sprayed from the nozzle into the second oil box 502 to the first transmission gear 307, the second transmission gear 308, and the first passive gear 40 2 and the second passive gear 403 are lubricated, while the other part of the hydraulic oil will enter the first oil box 501 through the delivery pipe 504 to lubricate the meshing transmission gear pair 302 and reduce the temperature in the first oil box 501 and the second oil box 502. The lubricating oil falling into the bottom of the first oil box 501 will flow into the second oil box 502 through the delivery pipe 505, and the rotating auger rotating shaft 512 will transport the lubricating oil accumulated in the second oil box 502 back to the oil inlet box 503 through the return pipe 513, so as to circulate lubrication and cool down. When the temperature difference among the first semiconductor chip 506, the second semiconductor chip 507 and the third semiconductor chip 508 arranged in 02 is reduced to be consistent, the voltage in the series circuit disappears, the relay 509 disconnects the voltage supplied to the rotating motor 510, and the temperature of the equipment in the first oil box 501 and the second oil box 502 is reduced and lubrication effect is obtained. For reducers, motors and other important components, excessively high temperatures may cause aging, deformation, wear, etc. of the materials.
