Description

Technical Field

[0001] This invention relates to the field of lubricating oil pipe technology, and in particular to a lubricating oil pipe for a transmission in a new energy vehicle. Background Technology

[0002] In new energy vehicles, transmission oil lines are typically used to deliver lubricating oil from the transmission to various components, ensuring smooth and efficient operation of the transmission. Transmission oil not only lubricates but also helps cool and clean internal parts, preventing wear and carbon buildup, and extending the transmission's lifespan. Therefore, the design and performance of the oil lines directly affect the transmission's efficiency and the overall performance of the new energy vehicle's powertrain.

[0003] Besides the transmission lubrication lines, other components of new energy vehicles, such as the battery management system (BMS), electric drive system, thermal management system, and power electronics system, also play a crucial role in the overall performance of the vehicle. The coordination between the transmission and these systems depends on the precise design and collaborative operation of various components. Therefore, the overall coordination and reliability of new energy vehicle components have a critical impact on the overall performance and lifespan of the vehicle.

[0004] The prior art publication CN221857490U provides a transmission lubricating oil pipeline structure for automobiles. By connecting the threaded sleeve at the end of the pipeline body to the threaded pipe, the push block at the end of the pipeline body drives the trapezoidal clamping block to be inserted into the reserved groove. Then, the threaded sleeve is screwed to move into the threaded pipe. The trapezoidal clamping block will squeeze the flexible connecting tube tightly against the outside of the clamping tube. The flexible connecting tube is made of elastic rubber tubing, which can fit tightly with the clamping tube to reduce oil leakage at the connection and improve the performance of the transmission lubricating oil pipeline structure for automobiles.

[0005] As lubricating oil flows through the pipes, sludge accumulates on the inner walls. This sludge not only affects the flow efficiency of the lubricating oil but can also cause blockages, impacting the lubrication of the transmission and even damaging internal parts. Existing lubrication pipes do not automatically self-clean themselves from the sludge, requiring manual intervention for regular inspection and cleaning. This increases maintenance costs and may lead to delayed maintenance, affecting the transmission's lifespan.

[0006] In summary, the existing technology lacks a technique for automatic internal wall maintenance of transmission lubrication lines. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting up a piston column and pipe wall treatment mechanism, when the piston column moves on the inner wall of the lubricating oil pipe, it can drive the conical scraper to rotate, which can actively remove the sludge on the inner wall of the lubricating oil pipe without manual intervention, reducing the frequency and difficulty of regular maintenance. Combined with the self-rotation cleaning function of the conical scraper, it can not only effectively remove the sludge in the lubricating oil pipe, but also improve the lubricating oil flow efficiency, extend the service life of the transmission, reduce maintenance costs, and improve the reliability and safety of the entire system.

[0019] 2. By setting up an inflation seat and an air guide reset mechanism, while the transmission mechanism drives the pipe wall treatment mechanism to move, it can drive the inflation seat to continuously inflate the lubricating oil pipe. The air pressure pushes the piston column and the pipe wall treatment mechanism to move and maintain within the lubricating oil pipe. At the same time, the air guide reset mechanism can drive the air guide hose to rewind while the transmission mechanism drives the pipe wall treatment mechanism to move, thereby automatically pulling the piston column back to its original position. This enables automatic cleaning and maintenance of the lubricating oil pipe, and the air pressure drives the piston column for precise cleaning. The automatic reset mechanism simplifies the operation process and can further improve the cleaning efficiency of the lubricating oil pipeline and the stability of the system.

[0020] 3. By setting guide seats A and B, the lubricating oil pipeline is sealed and sludge is collected. The lubricating oil is then filtered through the filter element tube and returned. This has multiple advantages such as high efficiency and cleaning, automated operation, lubricating oil recycling, reduced maintenance costs, improved system reliability and environmental protection.

[0040] like Figure 8 As shown, the air guiding and reset mechanism 8 includes a hollow tube frame 801.

An annular rack 802 is fixedly connected to the upper end of the hollow tube frame 801, and the annular rack 802 is meshed with the transmission wheel 403 for transmission. An air guiding hose 803 is wound on the hollow tube frame 801. One end of the air guiding hose 803 is fixedly connected to the inner wall of the hollow tube frame 801, and the other end of the air guiding hose 803 extends through the inner wall of the piston column 4 to the outside and is fixedly connected to a double-port air guiding pipe B804. Both ends of one side of the double-port air guiding pipe B804 are fixedly connected to the inner wall of the guide seat A3. An electric one-way valve is fixedly installed inside both ends of one side of the double-port air guiding pipe B804.

[0041] like Figure 9 As shown, a guide seat B901 is slidably fitted inside the oil treatment seat 9. A guide hole B902 is formed through the upper end of the guide seat B901, and a drain hole 903 is formed through the lower end of the guide seat B901. An electric valve is installed inside the drain hole 903. An electric actuator B904 is fixedly connected to the inner wall of the upper end of the guide seat B901. The other end of the electric actuator B904 is fixedly connected to the inner wall of the top of the oil treatment seat 9. A return pipe 905 is fixedly connected to the outer wall of one side of the oil treatment seat 9. One end of the return pipe 905 is fixedly connected through the inner wall of the lubricating oil pipe 1, and the other end of the return pipe 905 is fixedly connected to a filter element tube via a flange. The other end of the filter element tube is fixedly connected to the bottom opening of the oil treatment seat 9 via a flange. The electric valve is an electric ball valve: the rotation of the ball is controlled by an electric actuator to open or close the valve. A sealing gasket is provided on the outer wall of the guide seat B901.

[0042] Working principle: When it is necessary to clean and maintain the inner wall of the lubricating oil pipe 1, the electric actuators A302 and B904 are used to drive the guide seat A3 and guide seat B901 to move respectively, so that the guide hole A301 and guide hole B902 are misaligned with the inner wall of the lubricating oil pipe 1, thereby sealing both ends of the lubricating oil pipe 1. After the guide seat A3 moves, the contact rod 202 is unrestricted and will drive the cleaning cover 203 to move upward under the action of the tension spring 204, so that the air intake filter pipe 201 is open.

[0043] Then the system controls the exhaust solenoid electric check valve in the dual-port air duct A703 to open, controls the intake solenoid electric check valve in the dual-port air duct B804 to open, and simultaneously controls the electric ball valve in the guide seat B901 to open.

[0044] Then, the motor 601 drives the connected drive wheel 602 to rotate. At this time, the drive wheel 602 drives the L-shaped rod 603 to rotate. At this time, the other end of the L-shaped rod 603 will make a circular motion, thereby driving the piston plate 701 connected to the opening frame 702 to move back and forth. At this time, the external air will be filtered through the air intake filter pipe 201 and enter the air guide hose 803 through the air intake electromagnetic electric one-way valve in the double-port air guide pipe B804. It will then be injected into the hollow coil frame 801 through the air guide hose 803, and then into the air inflator 7 through the hollow coil frame 801. Finally, it will be injected into the space between the guide seat A3 and the piston column 4 through the air intake electromagnetic electric one-way valve in the double-port air guide pipe B804. Through the air pressure, the piston column 4 can be pushed to move.

[0045] At the same time, the rotating drive wheel 602 will drive the worm 502 connected to the driven wheel 503 to rotate, so that the worm 502 can drive the conical scraper 501 to rotate and scrape off the sludge on the inner wall of the lubricating oil pipe 1.

[0046] At the same time, the worm gear 502 will drive the worm wheel 402 to rotate, which will drive the transmission wheel 403 connected to the universal joint assembly 401 to rotate, so that the transmission wheel 403 can drive the hollow hose reel 801 connected to the ring rack 802 to rotate, so that the hollow hose reel 801 can realize the action of releasing the air guide hose 803.

[0047] When the piston rod 4 moves, the tapered scraper 501 can collect the sludge and oil in the lubricating oil pipe 1 by injecting it into the inner wall of the oil treatment seat 9 through the guide hole B902 on the guide seat B901 via the electric ball valve.

[0048] When cleaning and maintaining the lubricating oil pipe 1, first close the electric ball valve, the exhaust solenoid electric check valve in the double-port air pipe A703 and the intake solenoid electric check valve in the double-port air pipe B804, and open the intake solenoid electric check valve in the double-port air pipe A703 and the exhaust solenoid electric check valve in the double-port air pipe B804. At this time, when the piston plate 701 moves back and forth, the air between the guide seat A3 and the piston column 4 can be discharged. Then, the motor 601 drives the connected drive wheel 602 to rotate in the opposite direction. At this time, the hollow tube reel 801 will rotate in the opposite direction, so as to drive the air guide hose 803 to retract and drive the piston column 4 to retract into the guide seat A3.

[0049] Then, electric actuators A302 and B904 are used to drive guide seat A3 and guide seat B901 to reset respectively. At this time, guide seat B901 will squeeze the oil containing sludge. After being filtered by the filter core tube, the oil is reinjected into the lubricating oil pipe 1 through the return pipe 905. At the same time, guide seat A3 can contact and squeeze contact rod 202, causing contact rod 202 to drive the connected cleaning cover 203 to move down and reset, sealing the opening of the air intake filter pipe 201.
