Abstract

This invention relates to the field of engine component technology and discloses a low-leakage VVT ​​phaser assembly, including a housing with a cover on the front surface and a stator and rotor inside; a fastening mechanism on the front surface of the cover; a debris collection mechanism on both sides of the blades; and an anti-impact mechanism on both sides of the stator. A limiting sleeve is fitted over the bolts connected to the stator. A moving insert and pressure plate, in conjunction with magnetic force and a fitting seat, block and fix the limiting sleeve to restrict bolt rotation. Engine oil flows into the collection box along the throttling ramp and flows at the intercepting plate. When the blades approach the stator, they compress the rubber pad, causing the receiving seat to move inwards and retract the spring into the hollow interior.

Description

Technical Field

[0001] This invention relates to the field of engine component technology, specifically to a low-leakage VVT ​​phaser assembly. Background Technology

[0002] VVT phaser is the core actuator of the engine's variable valve timing system. It mainly relies on the hydraulic difference generated by the internal engine oil to drive the rotor to deflect inside the stator, changing the relative angle between the external gear and the internal shaft to adjust the valve timing. In actual operating environments, the vibration generated by the engine is directly transmitted to the phaser assembly, causing the fastening bolts connecting the cover and the stator to rotate and loosen, resulting in a loss of clamping force at the joint surface between the cover and the stator. Internal engine oil leaks to the outside along the loose gaps, disrupting the internal hydraulic balance. As oil circulates, metal debris enters the cavity between the stator and rotor. With the flow of oil, it gets stuck in the mating gap between the inner wall of the stator and the tip of the blade. When the blade deflects, the metal debris it carries scratches the sealing surface, causing wear on the mating surface and forming a connecting channel, resulting in internal leakage of oil between adjacent cavities. When the hydraulically driven blade deflects to its limit position, the blade sidewall and the stator sidewall come into direct contact and collide. The continuous rigid impact causes the blade edge and the stator force surface to undergo metal plastic deformation, which changes the initial design assembly gap and causes the sealing performance of the phaser assembly to decrease. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a low-leakage VVT ​​phaser assembly, which solves the problems of vibration-induced bolt loosening and oil leakage, oil debris scratching the sealing surface leading to internal cross-contamination, and blade deflection hard impacting the stator causing structural deformation.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a low-leakage VVT ​​phaser assembly, comprising a housing, a housing cover on the front surface, and a stator and a rotor disposed inside, providing internal component housing space and foundation support; a fastening mechanism disposed on the front surface of the housing cover, used to restrict the rotation of bolts passing through the housing cover and connected to the stator to prevent oil leakage; a debris collection mechanism disposed on both sides of blades fixed to the outer wall of the rotor, used to intercept and collect debris in the oil; and an anti-impact mechanism disposed on both sides of the stator, used to buffer the compressive force generated when the blades approach the stator.

[0005] Preferably, a gear is fixedly connected to the outer surface of the housing, a bolt is threaded inside the housing cover, and the bolt is threaded to the stator. A rotating shaft is installed inside the housing, and multiple oil inlet holes are opened on the outer wall of the rotating shaft. The rotor is sleeved on the outer wall of the rotating shaft. The oil enters the internal cavity through the oil inlet holes on the outer wall of the rotating shaft. The rotor and the rotating shaft are deflected inside the housing by relying on the hydraulic difference on both sides, thereby changing the relative angle between the gear and the rotating shaft to complete the phase adjustment.

[0006] Preferably, the fastening mechanism includes a limiting sleeve, and the limiting sleeve is connected to the bolt sleeve, and a connecting plate is fixedly connected to the outside of the limiting sleeve.

[0007] Preferably, a rod is inserted through the inside of the connecting plate, and a hollow tube is fitted into the outer wall of the rod, and the hollow tube is fixedly connected to the front surface of the cover; the hollow tube guides and supports the movement of the rod.

[0008] Preferably, one end of the insertion rod is provided with a first magnet, and the other end of the insertion rod is fixedly connected to a pressure plate. The rear surface of the pressure plate is provided with a second magnet, and the outer wall of the second magnet is fitted with a fitting seat, which is fixedly connected to the front surface of the shell cover. The movable connecting plate drives the insertion rod to slide inside the hollow tube. The insertion rod drives the first magnet and the pressure plate to move synchronously. The pressure plate drives the second magnet to fit into the fitting seat. The position of the limiting sleeve is fixed by the magnetic attraction between the first magnet and the second magnet and the physical blocking of the fitting seat. The limiting sleeve is used to fit against the outer surface of the bolt to form a limit, restricting the bolt from rotating and preventing the bolt from loosening due to vibration and causing oil leakage.

[0009] Preferably, the debris collection mechanism includes a throttling plate, and the throttling plate is fixedly connected to the inner wall of the blade, and a collection box is fixedly connected to the upper surface of the throttling plate.

[0010] Preferably, the upper surface of the collection box is open, and an interceptor plate is fixedly connected inside the collection box. The oil flows into the collection box along the throttling ramp and flows over the interceptor plate. The interceptor plate forms a physical barrier and changes the local flow velocity, trapping metal debris mixed with the oil at the bottom of the collection box. This prevents impurities from getting stuck in the stator and blade mating gap due to random oil flow, causing scratches on the contact end face, maintaining the flatness of the component mating surface and reducing the risk of internal cross-cavity.

[0011] Preferably, the anti-collision mechanism includes a spring, one end of which is fixedly connected to the outer wall of the stator and extends into the interior of the stator, and the other end of the spring is fixedly connected to a storage base, which is hollow.

[0012] Preferably, the storage base has a spherical ball inside and a support frame fixedly connected to the outer wall of the storage base.

[0013] Preferably, a rubber pad is provided on one side of the support frame, and the rubber pad is positioned facing the blade, with the rubber pad in contact with the blade. When the blade deflects and approaches the stator, it contacts the rubber pad and applies pressure. The rubber pad deforms to absorb the initial contact stress. The support frame is pressed and pushes the storage seat to move into the stator. When the storage seat is pressed, the internal hollow space accommodates the spring, causing the spring and the storage seat to retract into the stator together. At the same time, the movable ball connected in the storage seat is compressed and generates relative displacement, which is used to distribute the off-center load applied to the surface of the support frame, prevent the storage seat from getting stuck, provide buffer space for the contact between the blade and the stator, and prevent the blade from hitting the stator hard and causing structural deformation.

[0014] This invention provides a low-leakage VVT ​​phaser assembly. It offers the following advantages: 1. This invention provides a fastening mechanism on the front surface of the housing cover, which fits the limiting sleeve over the bolt. The moving connecting plate drives the insert rod and the pressure plate to move synchronously. The pressure plate drives the second magnet to engage with the fitting seat. The magnetic force generated by the first magnet and the second magnet, combined with the physical blocking of the fitting seat, fixes the position of the limiting sleeve. The limiting sleeve restricts the bolt rotation, preventing the bolt from loosening during equipment operation and vibration, thus preventing external oil leakage and maintaining the tightness and sealing between the components.

[0015] 2. This invention provides a debris collection mechanism on both sides of the blades. The engine oil is guided by the throttling plate into the collection box with an open surface. The engine oil flows through multiple channels inside the collection box, passing over the interception plate. The interception plate forms a barrier to intercept and collect the debris mixed in with the engine oil inside the collection box. This prevents impurities from getting stuck in the gap between the stator and the blade and causing end face scratches. It also ensures the flatness of the contact surface of the moving parts during operation and reduces the risk of internal combustion engine oil leakage.

[0016] 3. This invention provides anti-collision mechanisms on both sides of the stator. When the blades deflect towards the stator, they contact the rubber pads on one side of the support frame. The blades compress the rubber pads, causing deformation that absorbs the initial contact force. The support frame pushes the hollow storage seat into the stator. When the storage seat is compressed, the internal space stores the spring, causing the spring and the storage seat to retract into the reserved space inside the stator. The pressure on the movable ball inside the storage seat creates a relative displacement that distributes the surface force, thus buffering the contact between the blades and the stator and preventing the blades from impacting the stator and causing structural deformation.

[0019] The technical solutions in 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.

[0020] Please see the appendix Figure 1 -Appendix Figure 9 This invention provides a low-leakage VVT ​​phaser assembly, comprising: The housing 1 has a cover 3 on its front surface and a stator 5 and a rotor 11 inside, which provide space for internal components and basic support. Fastening mechanism 8, located on the front surface of housing cover 3, is used to restrict the rotation of bolt 4 that passes through housing cover 3 and is connected to stator 5 to prevent oil leakage; The debris collection mechanism 9 is set on both sides of the blades 7 fixed to the outer wall of the rotor 11, and is used to intercept and collect debris in the oil. The anti-collision mechanism 10 is set on both sides of the stator 5 to buffer the squeezing force generated when the blade 7 approaches the stator 5.

[0021] Please see the appendix Figure 2 Appendix Figure 5 Appendix Figure 6 and attached Figure 7 In one embodiment of the present invention, a gear 2 is fixedly connected to the outer surface of the housing 1, a rotating shaft 6 is provided inside the housing 1, a plurality of oil inlet holes are provided on the outer wall of the rotating shaft 6, the rotor 11 is sleeved on the outer wall of the rotating shaft 6, the debris collection mechanism 9 includes a throttling inclined plate 91, and the throttling inclined plate 91 is fixedly connected to the inner wall of the blade 7, a collection box 92 is fixedly connected to the upper surface of the throttling inclined plate 91, the upper surface of the collection box 92 is open, and an intercepting plate 93 is fixedly connected inside the collection box 92; Specifically: The external power drives the gear 2, which is fixedly connected to the outer surface of the housing 1, to rotate. The gear 2 drives the housing 1 and the stator 5, which is fixedly connected inside the housing 1, to rotate synchronously. The oil enters the housing 1, passes through multiple oil inlet holes opened on the outer wall of the rotating shaft 6 inside the housing 1, and flows into the cavity formed between the rotor 11 sleeved on the outer wall of the rotating shaft 6 and the blades 7 fixed on the outer wall of the rotor 11 and the stator 5. The hydraulic pressure difference generated by the oil on both sides of the cavity drives the rotor 11 and the rotating shaft 6 to deflect inside the housing 1, changing the relative angle between the gear 2 and the rotating shaft 6 to complete the phase adjustment. When the engine oil flows inside the cavity, it generates a directional flow. The flow contacts the debris collection mechanism 9 set on both sides of the blade 7. The engine oil flows along the throttling inclined plate 91 fixedly connected to the inner wall of the blade 7. The inclination angle of the throttling inclined plate 91 guides the flow of the engine oil, causing the engine oil to flow into the collection box 92 fixed on the upper surface of the throttling inclined plate 91. The engine oil enters the collection box 92 with an opening on the upper surface and contacts the intercepting plate 93 fixedly connected inside the collection box 92. The intercepting plate 93 changes the straight flow state of the engine oil, guiding the engine oil to flow through the intercepting plate 93 in a multi-channel manner inside the collection box 92. The intercepting plate 93 physically blocks and intercepts the debris in the engine oil. In practical applications, the multi-channel flow path inside the collection box 92 guides a local change in the oil flow rate, causing large metal debris to be deposited at the bottom of the collection box 92 under the combined effect of reduced flow rate and physical obstruction. This prevents impurities from being stuck in the gap between the stator 5 and the blade 7 due to random oil flow, thus preventing scratches on the contact surface. It also ensures the flatness and sealing performance of the contact surface when the moving parts are in operation, and reduces the probability of internal oil leakage.

[0022] Please see the appendix Figure 1 Appendix Figure 8 and attached Figure 9In one embodiment of the present invention, the inner thread of the cover 3 is connected to a bolt 4, and the bolt 4 is connected to the inner thread of the stator 5. The fastening mechanism 8 includes a limiting sleeve 81, and the limiting sleeve 81 is sleeved and connected to the bolt 4. The outer side of the limiting sleeve 81 is fixedly connected to a connecting plate 82. The inner side of the connecting plate 82 has a through rod 86. The outer wall of the through rod 86 is fitted with a hollow tube 83, and the hollow tube 83 is fixedly connected to the front surface of the cover 3. One end of the through rod 86 is provided with a first magnet 87, and the other end of the through rod 86 is fixedly connected to a pressure plate 85. The rear surface of the pressure plate 85 is provided with a second magnet 88. The outer wall of the second magnet 88 is fitted with a fitting seat 84, and the fitting seat 84 is fixedly connected to the front surface of the cover 3. Specifically: Bolt 4 is inserted into the shell cover 3 located on the front surface of the housing 1 and threaded into the stator 5 to complete the basic assembly. The limiting sleeve 81, whose inner contour matches the outer contour of bolt 4, is fitted onto the outside of bolt 4. The connecting plate 82, which is fixedly connected to the outside of the limiting sleeve 81, is moved. The connecting plate 82 is driven by force to move the insert rod 86 that passes through it. The insert rod 86 slides in a straight line inside the hollow tube 83. The hollow tube 83 is fitted into the outer wall of the insert rod 86 and fixedly connected to the front surface of the shell cover 3, which guides the movement trajectory of the insert rod 86 and provides radial support. The insertion rod 86 moves forward, causing the first magnet 87 at one end and the pressure plate 85 fixedly connected at the other end to move synchronously. The pressure plate 85 causes the second magnet 88 on the rear surface to move closer to the fitting seat 84, so that the outer wall of the second magnet 88 fits into the fitting seat 84 fixedly connected to the front surface of the cover 3. The magnetic attraction generated by the proximity of the first magnet 87 and the second magnet 88, together with the physical obstruction formed by the inner wall of the fitting seat 84 on the outer wall of the second magnet 88, fixes the position of the limiting sleeve 81. The limiting sleeve 81 fixes and limits the bolt 4 in a circumferential manner, preventing the bolt 4 from loosening and falling off during long-term engine operation, which would lead to oil leakage. In practical applications, the inner wall of the limiting sleeve 81 fits tightly with the outer surface of the bolt head 4, forming a physical limiting structure on the outside to restrict the rotation of the bolt 4. At the same time, the constant adsorption force generated by the first magnet 87 and the second magnet 88 in conjunction with the fitting seat 84 resists the displacement tendency caused by the high-frequency vibration of the engine and maintains the clamping force between the shell cover 3 and the stator 5.

[0023] Please see the appendix Figure 3 and attached Figure 4In one embodiment of the present invention, the anti-collision mechanism 10 includes a spring 101. One end of the spring 101 is fixedly connected to the outer wall of the stator 5 and extends into the interior of the stator 5. The other end of the spring 101 is fixedly connected to a storage seat 104, and the storage seat 104 is hollow. A ball 102 is movably connected inside the storage seat 104. A support frame 105 is fixedly connected to the outer wall of the storage seat 104. A rubber pad 103 is provided on one side of the support frame 105, and the rubber pad 103 is positioned facing the blade 7 and is in contact with the blade 7. Specifically: when the rotating shaft 6 drives the rotor 11 and the blade 7 to deflect, the blade 7 moves closer to the anti-collision mechanism 10 provided on both sides of the stator 5. The side wall of the blade 7 is in contact with the rubber pad 103 provided on one side of the support frame 105. The blade 7 compresses the rubber pad 103, and the support frame 105 is pushed by the pressure to move the storage seat 104 fixedly connected to the outer wall towards the inside of the stator 5. When the storage base 104 moves, it compresses the spring 101 fixed between the storage base 104 and the outer wall of the stator 5. At the same time, the ball 102 movably connected inside the storage base 104 generates relative displacement under pressure. Since the storage base 104 is hollow, when it is continuously compressed, the hollow space inside the storage base 104 will store the compressed spring 101 inside. With the structure that one end of the spring 101 extends into the stator 5, the spring 101 and the storage base 104 will retract smoothly into the space reserved inside the stator 5 when compressed. This will prolong the contact time between the blade 7 and the stator 5 and buffer the contact stress. In practical applications, the rubber pad 103 generates initial elastic deformation to absorb the initial contact energy, the spring 101 and the storage seat 104 that retracts into the stator 5 provide a secondary telescopic buffer space, the ball 102 undergoes a slight relative displacement inside the storage seat 104, changing the position of the contact point to evenly distribute the asymmetrical force applied to the surface of the support frame 105, preventing uneven wear and jamming due to uneven force when the storage seat 104 moves into the stator 5, and avoiding the blade 7 from hard impacting the stator 5 and causing plastic deformation of the internal metal structure.

[0024] Working principle: External power drives gear 2, which is fixedly connected to the outer surface of housing 1, to rotate. Gear 2 drives housing 1 and stator 5, which is fixedly connected inside housing 1, to rotate synchronously. Oil enters the interior of housing 1, passes through multiple oil inlets on the outer wall of rotating shaft 6 inside housing 1, and flows into the cavity formed between rotor 11, which is sleeved on the outer wall of rotating shaft 6, and blades 7 fixed on the outer wall of rotor 11, and stator 5. The hydraulic pressure difference generated by the oil on both sides of the cavity drives rotor 11 and rotating shaft 6 to deflect inside housing 1, changing the pressure difference between gear 2 and rotating shaft 6. The relative angle completes the phase adjustment. When the oil flows inside the cavity, it comes into contact with the debris collection mechanism 9 set on both sides of the blade 7. The oil flows along the throttling inclined plate 91 fixedly connected to the inner wall of the blade 7. The throttling inclined plate 91 guides the oil into the collection box 92 fixed on the upper surface of the throttling inclined plate 91. The oil enters the collection box 92 with an opening on the upper surface and comes into contact with the interception plate 93 fixedly connected inside the collection box 92. The oil flows through multiple channels inside the collection box 92, passing over the interception plate 93. The interception plate 93 intercepts and collects the debris in the oil. Bolt 4 is inserted into the cover 3 located on the front surface of housing 1 and threaded into the stator 5. The limiting sleeve 81 of the fastening mechanism 8 is fitted over bolt 4. The connecting plate 82, fixedly connected to the outside of the limiting sleeve 81, is moved. The connecting plate 82 drives the insertion rod 86, which passes through the connecting plate 82, to move. The insertion rod 86 slides inside the hollow tube 83, which is fitted into the outer wall of the insertion rod 86 and fixedly connected to the front surface of the cover 3, providing guidance and support for the movement of the insertion rod 86. The insertion rod 86 drives one end of the insertion rod 86... The first magnet 87 and the pressure plate 85 fixedly connected to the other end of the insertion rod 86 move synchronously. The pressure plate 85 drives the second magnet 88 set on the rear surface of the pressure plate 85 to move closer to the fitting seat 84, so that the outer wall of the second magnet 88 fits into the fitting seat 84 fixedly connected to the front surface of the shell cover 3. The position of the fixed limiting sleeve 81 is fixed by the magnetic force generated by the first magnet 87 and the second magnet 88 and the physical blocking of the fitting seat 84. The bolt 4 is fixed and limited by the limiting sleeve 81 to prevent the bolt 4 from loosening during long-term operation and causing oil leakage. When the rotating shaft 6 drives the rotor 11 and the blade 7 to deflect, the blade 7 moves closer to the anti-collision mechanism 10 set on both sides of the stator 5. The blade 7 comes into contact with the rubber pad 103 set on one side of the support frame 105. The blade 7 squeezes the rubber pad 103, and the support frame 105 pushes the storage seat 104, which is fixedly connected to the outer wall of the support frame 105, to move inward toward the stator 5. The storage seat 104 squeezes the spring 101 fixed between the storage seat 104 and the outer wall of the stator 5. The ball 102, which is movably connected inside the storage seat 104, is compressed and generates relative displacement. Since the storage seat 104 is hollow, when it is squeezed, the hollow space inside the storage seat 104 will store the spring 101. With the spring 101 extending into the stator 5 at one end, the spring 101 and the storage seat 104 retract into the stator 5 together when squeezed, which serves to buffer the contact between the blade 7 and the stator 5.

[0025] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended specification and its equivalents.
