Description

Technical Field

[0001] This utility model relates to the field of engine technology, and in particular to an engine transmission and speed change structure. Background Technology

[0002] Engines and their internal transmission systems generate a significant amount of heat during high-speed operation. To ensure stable mechanical performance and extend service life, effective cooling of these critical components is essential. High temperatures reduce the viscosity of engine oil, decreasing its lubricating properties and potentially leading to excessive wear or even damage to parts. Therefore, equipping the transmission system with an efficient cooling system is crucial.

[0003] Currently, a common solution is to use an external forced-air cooling system. This system uses an oil pump to extract the high-temperature engine oil from inside the transmission structure, cool it through an external radiator, and then return it to the external system, forming a circulating cooling oil circuit. This method requires the use of high-pressure resistant oil pipes to connect the engine block to the external radiator, and the reliability and convenience of the connection points directly affect the performance of the entire system and the efficiency of subsequent maintenance.

[0004] In existing technologies, these oil pipes are typically fastened using traditional threaded joints or flanges. While these connection methods can meet basic sealing and securing requirements, they also have shortcomings in practical applications. On the one hand, when performing disassembly and assembly work in the compact engine compartment, using tools such as wrenches to operate on threads or bolts is often space-constrained and very inconvenient, which greatly reduces the efficiency of maintenance and repair.

[0005] More importantly, the engine generates continuous high-frequency vibrations during operation. Traditional threaded connection structures are at risk of gradually loosening fasteners under long-term vibration and periodic impacts from oil pressure. Once the connection loosens, it can lead to oil leakage, affecting heat dissipation and polluting the environment, or even cause oil pipes to detach, resulting in the transmission structure losing lubrication and cooling instantly and causing catastrophic mechanical failure.

[0006] Therefore, this utility model proposes an engine transmission speed change structure to overcome the shortcomings of the prior art. Utility Model Content

[0007] To overcome the above shortcomings, this utility model provides an engine transmission and speed change structure, which aims to improve the existing technology where the external oil pipe connections of the engine transmission and speed change structure are usually fastened with threads, making the disassembly and assembly process cumbersome and time-consuming, and posing a risk of loosening and oil leakage under vibration conditions.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: An engine transmission transmission structure includes: an engine, an oil pump, an oil filter, a radiator, a first oil pipe and a second oil pipe; and a quick-connect structure for connecting the first oil pipe and the second oil pipe, the structure including a housing fixedly connected to a first pipe that is the end of the first oil pipe, a pipe joint fixedly connected to a second pipe that is the end of the second oil pipe, a buckle provided on the pipe joint, a limiting buckle seat fixed inside the housing, a fixing ring that can slide axially on the first pipe, and a first magnet and a second magnet.

[0009] The buckle on the pipe fitting can be rotatably engaged with the limiting buckle seat inside the housing.

[0010] Furthermore, the first and second magnets are located inside the outer casing and are used to push the retaining ring with magnetic force, so that one end of the retaining ring abuts against the buckle, thereby locking the buckle.

[0011] Preferably, the oil pump is connected to the engine drive, the inlet of the oil filter element is connected to the outlet of the oil pump, the outlet of the first oil pipe is connected to the inlet of the radiator, the inlet of the second oil pipe is connected to the outlet of the radiator, and the outlet of the second oil pipe is connected to the engine, so as to form an oil cooling circulation loop.

[0012] Preferably, the limiting buckle seat is provided with a buckle groove that matches the buckle.

[0013] Preferably, as one specific implementation, the buckle includes an elastic unlocking part capable of elastically deforming to disengage from the slot.

[0014] Preferably, the outer shell has a hollow structure and covers the outside of the first pipe.

[0015] Preferably, the limiting buckle seat, the first magnet, and the second magnet are all fixedly connected to the inner wall of the outer shell.

[0016] Preferably, the first magnet and the second magnet are located between the fixing ring and the limiting buckle seat.

[0017] Preferably, as a specific implementation, the magnetic poles of the first magnet and the second magnet are configured to repel each other from the corresponding magnetic poles of the fixed ring.

[0018] This utility model has the following beneficial effects: 1. This utility model solves the problem that existing oil pipelines mostly use threaded or flanged connections, which require tools for disassembly and assembly, are cumbersome, time-consuming, and have low maintenance efficiency. It achieves the beneficial effect of quickly disassembling and assembling pipelines without tools, greatly improving work efficiency.

[0019] 2. This utility model solves the problem that the existing pipe connection structure is prone to loosening under the high-frequency vibration of the engine and the impact of the high-pressure oil circuit, resulting in connection failure or oil leakage and poor reliability. It achieves the beneficial effect of forming a secondary lock on the buckle, effectively preventing accidental loosening of the connection, and significantly enhancing the connection firmness and sealing performance.

[0020] 3. This utility model solves the problem in the prior art where insufficient heat dissipation in some engine transmission and gear transmission structures leads to excessively high oil temperature, reduced lubrication performance, and thus accelerated wear of key components. It achieves the beneficial effects of effectively reducing the working temperature of transmission and gear transmission components, ensuring the lubrication performance of the oil, and extending the service life of the engine.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3This utility model provides an embodiment of an engine transmission transmission structure, which includes an engine 1, an oil pump 2, an oil filter 3, a radiator 5, a first oil pipe 4, and a second oil pipe 6. The oil pump 2 is connected to the engine 1 in a transmission manner. The inlet of the oil filter 3 is connected to the outlet of the oil pump 2. The outlet of the first oil pipe 4 is connected to the inlet of the radiator 5. The inlet of the second oil pipe 6 is connected to the outlet of the radiator 5, and the outlet of the second oil pipe 6 is connected to the engine 1, thereby forming a complete oil cooling circulation loop. In order to achieve convenient and reliable disassembly and assembly between the first oil pipe 4 and the second oil pipe 6, the end of the first oil pipe 4 is set as a first pipe 8, and the end of the second oil pipe 6 is set as a second pipe 13. The end of the first pipe 8 is fixedly connected to a housing 7, and the end of the second pipe 13 is fixedly connected to a pipe joint 12.

[0025] The housing 7 has a fixed limiting buckle seat 11 inside, and the pipe joint 12 is provided with a buckle 14. When the first pipe 8 is connected to the second pipe 13, the buckle 14 can be rotatably engaged with the limiting buckle seat 11 to achieve initial axial fixation and circumferential locking. To further enhance the reliability of the connection, the housing 7 also has a fixed ring 15 that can slide axially on the first pipe 8, as well as a first magnet 9 and a second magnet 10 for pushing the fixed ring 15. After the buckle 14 is engaged with the limiting buckle seat 11, the fixed ring 15 slides axially along the first pipe 8 under the magnetic force of the first magnet 9 and the second magnet 10 until one end of it tightly abuts against the buckle 14. This abutting action restricts the rotational freedom of the buckle 14, preventing the buckle 14 from accidentally unlocking due to reverse rotation caused by vibration or other reasons, thus ensuring the long-term stability of the pipe connection.

[0026] The outer shell 7 is a hollow structure that covers the outside of the first pipe 8 and provides it with protection. A limiting buckle seat 11 is fixedly connected to its inner wall. The limiting buckle seat 11 is provided with a groove that matches the buckle 14. The groove is used to circumferentially limit and axially guide the buckle 14 on the pipe joint 12. At the same time, the pipe joint 12 is correspondingly provided with a buckle 14. The shape and size of the buckle 14 are adapted to the groove of the limiting buckle seat 11. In the assembled state, the pipe joint 12 drives the buckle 14 to insert into the groove of the limiting buckle seat 11 and rotate to realize the snap-fit ​​between the two. This rotating snap-fit ​​structure ensures that the first pipe 8 and the second pipe 13 can quickly complete the initial locking after connection.

[0027] To further prevent the connection structure from loosening under vibration, a first magnet 9 and a second magnet 10 are fixedly connected to the inner wall of the outer shell 7. Inside the outer shell 7, a fixing ring 15 sleeved on the outer periphery of the first pipe 8 can slide axially in the first pipe 8. The first magnet 9 and the second magnet 10 are located between the fixing ring 15 and the limiting buckle seat 11, and the magnetic poles of the first magnet 9 and the second magnet 10 are set to repel each other with the corresponding magnetic poles of the fixing ring 15. When the buckle 14 is engaged in the limiting buckle seat 11, the magnetic repulsion will continue to push the fixing ring 15 to move axially until its end face abuts against the side of the buckle 14, thereby forming a physical block, effectively preventing the buckle 14 from rotating in the opposite direction, and greatly improving the reliability of the connection. When disassembly is required, simply apply external force to rotate the pipe joint 12 in the opposite direction, causing the buckle 14 to overcome the magnetic force and push the fixing ring 15 back, thus unlocking it. The buckle 14 also includes an elastic unlocking part that can be elastically deformed to disengage from the slot, making the disassembly process smoother.

[0028] In a preferred embodiment, in order to construct a clear and efficient oil cooling path, the oil pump 2 is connected to the engine 1, the inlet of the oil filter element 3 is connected to the outlet of the oil pump 2, the outlet of the first oil pipe 4 is connected to the inlet of the radiator 5, the inlet of the second oil pipe 6 is connected to the outlet of the radiator 5, and the outlet of the second oil pipe 6 is finally connected to the transmission and gearbox assembly inside the engine 1.

[0029] As another preferred embodiment, in order to achieve precise snap-fit ​​positioning and convenient unlocking operation, the limiting buckle seat 11 is provided with a slot that matches the buckle 14. The structural shape of the buckle 14 matches the contour of the slot to achieve a tight fit. In addition, the buckle 14 also includes an elastic unlocking part that can elastically deform to disengage from the slot. When the pipe joint 12 is rotated in the opposite direction, the elastic unlocking part can produce a slight deformation, thereby smoothly disengaging from the limiting of the slot.

[0030] As another preferred embodiment, in order to form an integrated installation platform and protect the internal components, the housing 7 is a hollow structure that covers the outside of the first pipe 8. The limiting buckle seat 11, the first magnet 9 and the second magnet 10 are all fixedly connected to the inner wall of the housing 7, thereby forming an integral connector seat.

[0031] In another preferred embodiment, in order to generate a stable and reliable locking thrust, the first magnet 9 and the second magnet 10 are located between the fixing ring 15 and the limiting buckle seat 11, and the magnetic poles of the first magnet 9 and the second magnet 10 are set to repel each other with the corresponding magnetic poles of the fixing ring 15. This non-contact magnetic repulsion provides the fixing ring 15 with a continuous and wear-free axial thrust, so that it is stably abutted against the buckle 14.

[0032] Working principle: When connecting the first pipe 8 and the second pipe 13, align the two ports, push the pipe connector 12 to allow the buckle 14 to enter the housing 7 and align with the slot entrance of the limiting buckle seat 11. Then, rotate the pipe connector 12, and the buckle 14 rotates along the guide track of the slot to the locking position, completing the initial mechanical locking. During this process, the retaining ring 15 is inside the housing 7 and is repelled by the magnetic force of the first magnet 9 and the second magnet 10, always maintaining a pre-tight force in the direction of the buckle 14. Once the buckle 14 is rotated into place, the retaining ring 15 immediately slides forward under its magnetic force, and its end face tightly abuts against the side of the buckle 14, forming an axial physical block on the buckle 14. This block prevents the buckle 14 from accidentally rotating out of control in the event of engine vibration or oil pressure fluctuation, thereby ensuring the long-term firmness and sealing of the connection.

[0033] When it is necessary to separate the pipes, the operator only needs to rotate the pipe joint 12 in the opposite direction by hand. The applied torque will first overcome the abutting friction and magnetic force generated by the first magnet 9 and the second magnet 10 pushing the fixing ring 15, forcing the fixing ring 15 to retract axially, making room for the buckle 14 to rotate. As the pipe joint 12 continues to rotate, the elastic unlocking part on the buckle 14 allows it to smoothly disengage from the slot of the limiting buckle seat 11. At this time, the first pipe 8 and the second pipe 13 can be easily pulled apart axially. The entire connection and separation process does not require any tools and is intuitive and quick to operate.

[0034] During engine 1 operation, oil pump 2 draws high-temperature engine oil from inside engine 1. The oil flows through oil filter element 3 for filtration, and then enters radiator 5 for forced air cooling through first oil pipe 4, first pipe 8, connected pipe joint 12, second pipe 13 and second oil pipe 6. The cooled and cleaned engine oil then flows back to the transmission and gearbox components inside engine 1 through the return oil line for lubrication and heat removal, and finally flows back to the oil pan, completing an efficient heat dissipation cycle.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
