Description

Technical Field

[0001] The present invention relates to the technical field of solenoid valves, and in particular to a solenoid valve used in a gearbox. Background Art

[0002] The Automated Manual Transmission (AMT) is developed on the basis of the traditional manual transmission. It retains the gear transmission structure and shifting mechanism of the manual transmission, but automatically controls the separation and combination of the clutch and the shifting action of the shift lever through the electronic control unit (ECU), pneumatic or electric actuator. The AMT has the advantages of low cost, diverse driving modes and high transmission efficiency, and has become the mainstream of modern cars. As an important component of the transmission, the solenoid valve has the problem of too small flow during the operation of the transmission, which will reduce the working efficiency of the system. For example, during the shifting process, insufficient flow may not provide enough pressure to the clutch or shifting actuator in time, resulting in a delay in shifting. This will cause the vehicle to have a long power interruption time when shifting, affecting the driving experience, especially in scenarios where fast shifting is required, such as downshifting and upshifting during rapid acceleration or deceleration.

[0003] Furthermore, in the prior art, the stator of the solenoid valve is often designed to extend into the mover for exhaust. This design reduces the electromagnetic force of the solenoid valve. At the same time, since the free length of the spring is too long and the rigidity is insufficient, this design causes the spring to bear a larger load during operation, aggravating the wear of the spring and having an adverse effect on the durability of the solenoid valve.

[0004] Therefore, it is necessary to improve the existing technology. Summary of the invention

[0005] The problem solved by the invention is to increase the electromagnetic force between the stator and the mover of the gearbox electromagnetic valve while reducing the air resistance and increasing the flow of the electromagnetic valve.

[0006] To solve the above problems, the present invention adopts the following technical solutions: a solenoid valve for a gearbox comprises: a stator, a mover, a nozzle and a buffer, the stator is provided with an air outlet, the air outlet has a first air outlet end and a first air inlet end; the mover is arranged on one side of the first air inlet end, the mover comprises a buffer mounting part, a nozzle mounting part and a ventilation groove, the buffer mounting part is arranged at one end of the mover, the nozzle mounting part is arranged at the other end opposite to the mover, and the ventilation groove is arranged on the outside of the buffer mounting part; the nozzle abuts the nozzle mounting part; the buffer is installed on the buffer mounting part; wherein, when the solenoid valve is energized, the mover abuts the stator, the buffer closes the first air inlet end, and the nozzle is away from the nozzle mounting part.

[0007] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: specifically, by arranging the buffer between the stator and the mover, while improving the electromagnetic force between the stator and the mover, when the stator and the mover are attracted, the buffer isolates the contact between the stator and the mover, which can effectively cushion the vibration and reduce noise.

[0008] Furthermore, when the solenoid valve is energized, the mover abuts against the stator, and the buffer closes the first air inlet. This design can accurately control the timing of gas on and off. When it is necessary to stop the gas supply or switch the gas path, the close contact between the mover and the stator and the effective closure of the first air inlet by the buffer can quickly and reliably cut off the path, ensuring the accuracy and stability of the control of the transmission-related path system, thereby helping to accurately control the pressure inside the transmission, achieve precise gear shifting operations, and improve the smoothness and response speed of gear shifting.

[0009] Furthermore, the solenoid valve is also provided with a valve sleeve, and the mover is also provided with a mover fixing part; the stator is arranged at one end inside the valve sleeve, and the mover is arranged at the other end inside the valve sleeve, and the valve sleeve is provided with an abutting part, and the abutting part is arranged at one end of the mover; the mover fixing part, the mover fixing part is arranged on the outside of the nozzle mounting part, and the mover fixing part is connected and fixed to the abutting part.

[0010] Compared with the prior art, the technical effect achieved by adopting this technical solution is that the valve sleeve provides a stable installation environment for the stator and the mover, and the stator is arranged at one end of the valve sleeve and the mover is arranged at the other end, so that the relative position of the two can be accurately fixed. This helps to maintain the stability of the internal structure of the entire solenoid valve during the frequent operation of the solenoid valve, especially when the mover moves frequently under the action of electromagnetic force, and reduces the possibility of displacement or collision between the stator and the mover due to external vibration or impact, thereby ensuring the normal operation of the solenoid valve and extending its service life.

[0011] At the same time, the mover is fixed by the abutment part so that the mover maintains a stable posture and position when subjected to the electromagnetic force to avoid shaking or deviation, thereby ensuring that the matching accuracy between the mover and the nozzle, stator and other components is always in good condition, which is conducive to the solenoid valve to achieve precise passage control function.

[0012] Furthermore, the solenoid valve is also provided with a tower spring, one end of which abuts against the abutting portion, and the other end of which is connected to the movable member fixing portion, and the tower spring is used to maintain the movable member in an abutting state with the nozzle.

[0013] Compared with the prior art, the technical effect achieved by adopting this technical solution is that one end of the tower spring abuts against the abutment part, and the other end is connected to the mover mounting part. This connection method provides a stable elastic support force for the mover. Compared with the prior art, the tower spring has better stability and longer service life, and can provide stable support for the mover and the nozzle.

[0014] Furthermore, the nozzle mounting part includes: an air inlet hole and a sealing gasket, wherein one side of the air inlet hole is connected to the ventilation groove and the other side is connected to the nozzle, and the sealing gasket is installed on the other side of the air inlet hole; the nozzle includes a nozzle port, the nozzle port is connected to the air inlet hole, and the sealing gasket covers the nozzle port; wherein, when the solenoid valve is energized, the sealing gasket opens the nozzle port.

[0015] Compared with the prior art, the technical effect achieved by adopting this technical solution is that one side of the air inlet of the nozzle mounting part is connected to the venting groove, and the other side is connected to the nozzle, and the sealing gasket is installed on the other side of the air inlet and shields the nozzle opening. In the initial state when the solenoid valve is not powered, the sealing gasket can effectively close the nozzle opening passage to ensure the sealing of the nozzle opening passage.

[0016] Furthermore, the sealing gasket also includes a ventilation fence and a sealing ring, the sealing ring shields the connection between the air inlet and the nozzle opening, and the ventilation fence is evenly distributed on the outside of the sealing ring.

[0017] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the ventilation fences are evenly distributed on the outside of the sealing ring. When the solenoid valve is not energized, the ventilation fences, the air inlet holes and the ventilation grooves form a passage and are discharged through the air outlet of the stator; when the solenoid valve is energized, the sealing gasket opens, the air outlet is closed, and the gas entering the passage is discharged from the nozzle mouth.

[0018] Furthermore, the nozzle also includes a second air inlet hole, which is connected to the ventilation fence and is evenly distributed on the outside of the nozzle opening.

[0019] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: Specifically, the gas enters the ventilation fence from the second air inlet and then enters the mover air inlet, so the design increases the flow rate of gas entering the nozzle. When the solenoid valve is energized, the gas no longer relies on a single air inlet to flow in, but can flow in through multiple second air inlets at the same time, thereby effectively increasing the gas flow rate.

[0020] Furthermore, the nozzle includes a second clamping platform, which is arranged outside the second air inlet, the valve sleeve is provided with a second clamping wall, the second clamping platform is clamped to the second clamping wall, and the second clamping platform is used to fix the nozzle.

[0021] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the clamping method of the second clamping platform and the second clamping wall can realize the precise installation and positioning of the nozzle in the valve sleeve. During the assembly process of the solenoid valve, this clamping structure can ensure that the relative position between the nozzle and other components such as the valve sleeve and the mover is accurate. This fixing method can effectively maintain the position stability of the nozzle during the long-term operation of the solenoid valve. Whether it is the vibration and impact suffered during the driving of the vehicle, or the internal stress generated by the frequent operation of the solenoid valve, the clamping structure can prevent the nozzle from displacement or loosening. The stable nozzle position helps to maintain the consistency and reliability of the gas circuit system, reduce the fluctuation of the passage parameters caused by the change of the nozzle position, improve the durability and service life of the solenoid valve, and reduce the risk of failure due to loose components, thereby ensuring the stability and reliability of the transmission control system.

[0022] Furthermore, the air outlet portion includes: a first air outlet hole and a first air inlet hole, the first air outlet hole is arranged at the first air outlet end, the first air inlet hole is arranged at the first air inlet end, and the aperture of the first air outlet hole is larger than the aperture of the first air inlet hole.

[0023] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: during the operation of the solenoid valve, when the gas is discharged from the air outlet, it enters the first air outlet with a large aperture from the first air inlet with a small aperture, thereby stabilizing the pressure of the gas when it is discharged and realizing precise control of the gas pressure.

[0024] Furthermore, the buffer component includes a buffer disk and a clamping disk, the diameter of the buffer disk is larger than the diameter of the first air inlet, and the diameter of the clamping disk is larger than the diameter of the buffer disk; the buffer component mounting portion is provided with a clamping space and a clamping protrusion, the clamping protrusion is provided on the wall of the clamping space, the buffer component is installed in the clamping space, and the clamping disk is fixed against the clamping protrusion.

[0025] Compared with the prior art, the technical effect achieved by adopting this technical solution is that the buffer component installation portion is provided with a clamping space and a clamping protrusion, and the clamping disc is fixed against the clamping protrusion, and this clamping structure enables the buffer component to be firmly installed in the buffer component installation portion. During the long-term operation of the solenoid valve, the buffer component will not be easily displaced or loosened, ensuring its reliability and stability in the action of closing the first air inlet end.

[0026] Furthermore, the ventilation groove includes a U-shaped opening and a ventilation hole, one end of the ventilation hole is connected to the U-shaped opening, and the other end of the ventilation hole is connected to the nozzle.

[0027] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by setting a U-shaped opening and a vent hole, the U-shaped opening is on the outside, and the air resistance encountered when the gas enters the U-shaped opening through the vent hole is reduced, thereby increasing the flow rate of the entire solenoid valve.

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] See also Figure 1-Figure 9, which is a solenoid valve 100 for a gearbox provided by an embodiment of the present invention, specifically comprising: a stator 10, a mover 20, a nozzle 30 and a buffer 40, the stator 10 is provided with an air outlet 11, the air outlet 11 has a first air outlet end and a first air inlet end; the mover 20 is arranged at one side of the first air inlet end, the mover 20 comprises a buffer mounting portion 22, a nozzle mounting portion 23 and a ventilation groove 21, the buffer mounting portion 22 is arranged at one end of the mover 20, the nozzle mounting portion 23 is arranged at the other end opposite to the mover 20, and the ventilation groove 21 is arranged on the outside of the buffer mounting portion 22; the nozzle 30 abuts against the nozzle mounting portion 23; the buffer 40 is installed on the buffer mounting portion 22; wherein, when the solenoid valve 100 is energized, the mover 20 abuts against the stator 10, the buffer 40 closes the first air inlet end, and the nozzle 30 is away from the nozzle mounting portion 23.

[0032] Specifically, by arranging the buffer 40 between the stator 10 and the mover 20, the electromagnetic force between the stator 10 and the mover 20 is increased. When the stator 10 and the mover 20 are attracted, the buffer 40 isolates the stator 10 from contact with the mover 20, thereby effectively absorbing vibration and reducing noise.

[0033] Preferably, the buffer member 40 may be made of rubber particles.

[0034] Furthermore, when the solenoid valve 100 is energized, the mover 20 abuts against the stator 10, and the buffer 40 closes the first air inlet. This design can accurately control the on-off timing of the gas. When it is necessary to stop the gas supply or switch the gas path, the mover 20 abuts against the stator 10 and the buffer 40 effectively closes the first air inlet, which can quickly and reliably cut off the passage, ensuring the accuracy and stability of the control of the transmission-related passage system, thereby helping to accurately control the pressure inside the transmission, achieve precise gear shifting operations, and improve the smoothness and response speed of gear shifting.

[0035] For further information, see Figure 1 , Figure 2 , Figure 4 , Figure 7 The solenoid valve 100 is also provided with a valve sleeve 60, and the mover 20 is also provided with a mover fixing portion 26; the stator 10 is arranged at one end of the interior of the valve sleeve 60, and the mover 20 is arranged at the other end of the interior of the valve sleeve 60; the valve sleeve 60 is provided with a butt portion 61, and the butt portion 61 is arranged at one end of the mover 20; the mover fixing portion 26 is arranged on the outside of the nozzle mounting portion 23, and the mover fixing portion 26 is connected and fixed to the butt portion 61.

[0036] The existence of the valve sleeve 60 provides a stable installation frame for the stator 10 and the mover 20. The stator 10 is arranged at one end of the valve sleeve 60, and the mover 20 is arranged at the other end, so that the relative positions of the two can be accurately fixed. This helps to maintain the stability of the internal structure of the entire solenoid valve 100 during the frequent operation of the solenoid valve 100, especially when the mover 20 frequently moves under the action of the electromagnetic force, and reduces the possibility of displacement or collision between the stator 10 and the mover 20 due to external vibration or impact, thereby ensuring the normal operation of the solenoid valve 100 and extending its service life.

[0037] At the same time, the mover 20 is fixed by the abutment portion 61, so that the mover 20 maintains a stable posture and position when subjected to the electromagnetic force, avoiding shaking or deviation, ensuring that the matching accuracy between the mover 20 and the nozzle 30, stator 10 and other components is always in a good state, which is conducive to the solenoid valve 100 to achieve precise passage control function.

[0038] Specifically, see Figure 1 , Figure 2 , Figure 4 The solenoid valve 100 is further provided with a tower spring 50 , one end of which abuts against the abutting portion 61 , and the other end of which is connected to the mover fixing portion 26 . The tower spring 50 is used to maintain the abutting state between the mover 20 and the nozzle 30 .

[0039] One end of the tower spring 50 abuts against the abutment portion 61, and the other end is connected to the mover mounting portion. In the present embodiment, the tower spring 50 has better stability and longer service life than ordinary springs, and can provide more stable support for the mover 20 and the nozzle 30. At the same time, when the solenoid valve 100 is powered off, the elastic force of the tower spring 50 will quickly take effect, prompting the mover 20 to quickly return to its initial position abutting against the nozzle 30, and quickly reset.

[0040] For further information, see Figure 1-Figure 4 as well as Figure 8 The nozzle mounting portion 23 includes: an air inlet hole 24 and a sealing gasket 25. One side of the air inlet hole 24 is connected to the vent groove 21, and the other side is connected to the nozzle 30. The sealing gasket 25 is installed on the other side of the air inlet hole 24. The nozzle 30 includes a nozzle port 31, which is connected to the air inlet hole 24. The sealing gasket 25 covers the nozzle port 31. When the solenoid valve 100 is energized, the sealing gasket 25 opens the nozzle port 31.

[0041] One side of the air inlet 24 of the nozzle mounting portion 23 is connected to the venting groove 21, and the other side is connected to the nozzle 30. The sealing gasket 25 is installed on the other side of the air inlet 24 and covers the nozzle opening 31. In the initial state where the solenoid valve 100 is not powered, the sealing gasket 25 can effectively close the passage of the nozzle opening 31 to ensure the sealing of the passage of the nozzle opening 31.

[0042] For further information, see Figure 8The sealing gasket 25 further includes a ventilation fence 28 and a sealing ring 27 . The sealing ring 27 shields the connection between the air inlet 24 and the nozzle opening 31 . The ventilation fence 28 is evenly distributed on the outer side of the sealing ring 27 .

[0043] Preferably, the sealing ring 27 is a protruding circular pad that abuts against the nozzle opening 31 , and the sealing ring 27 is made of rubber particles.

[0044] The ventilation fences 28 are evenly distributed on the outside of the sealing ring 27. When the solenoid valve 100 is not energized, the ventilation fences 28, the air inlet holes 24 and the ventilation grooves 21 form a passage and are discharged through the air outlet 11 of the stator 10. When the solenoid valve 100 is energized, the sealing gasket 25 opens, the air outlet 11 is closed, and the gas entering the passage is discharged from the nozzle opening 31.

[0045] For further information, see Figure 2 , Figure 3 , Figure 4 as well as Fig. 9 The nozzle 30 further includes a second air inlet hole 33 , which is in communication with the ventilation fence 28 , and the second air inlet holes 33 are evenly distributed on the outer side of the nozzle opening 31 .

[0046] The gas enters the ventilation grille 28 from the second air inlet 33 and then enters the mover air inlet 24. This design increases the flow rate of the gas entering the nozzle 30. When the solenoid valve 100 is powered on, the gas no longer relies solely on a single second air inlet 33 to flow in, but can flow in through multiple second air inlets 33 at the same time, effectively increasing the gas flow rate of the solenoid valve.

[0047] Specifically, see Figure 4 , Figure 7 as well as Fig. 9 The nozzle 30 includes a second clamping platform 32, which is arranged on the outer side of the second air inlet 33. The valve sleeve 60 is provided with a second clamping wall 62, and the second clamping platform 32 is clamped on the second clamping wall 62. The second clamping platform 32 is used to fix the nozzle 30.

[0048] The clamping method of the second clamping platform 32 and the second clamping wall 62 can realize the precise installation and positioning of the nozzle 30 in the valve sleeve 60. During the assembly process of the solenoid valve 100, this clamping structure can ensure that the relative position between the nozzle 30 and other components such as the valve sleeve 60 and the mover 20 is accurate. This fixing method can effectively maintain the position stability of the nozzle 30 during the long-term operation of the solenoid valve 100. Whether it is the vibration and impact suffered during the driving of the vehicle, or the internal stress generated by the frequent operation of the solenoid valve 100, the clamping structure can prevent the nozzle 30 from displacement or loosening. The stable position of the nozzle 30 helps to maintain the consistency and reliability of the air circuit system, reduce the fluctuation of the passage parameters caused by the change of the position of the nozzle 30, improve the durability and service life of the solenoid valve 100, and reduce the risk of failure due to loose components, thereby ensuring the stability and reliability of the gearbox control system.

[0049] For further information, see Figure 2-Figure 4 The air outlet portion 11 of the stator 10 includes: a first air outlet hole 12 and a first air inlet hole 13, the first air outlet hole 12 is arranged at the first air outlet end, the first air inlet hole 13 is arranged at the first air inlet end, and the aperture of the first air outlet hole 12 is larger than the aperture of the first air inlet hole 13.

[0050] Preferably, the first air inlet hole 13 is arranged to protrude from the first air inlet end and abut against the buffer member 40 .

[0051] During operation of the solenoid valve 100 , when gas is discharged from the gas outlet 11 , it enters the first gas outlet 12 with a larger aperture from the first gas inlet 13 with a smaller aperture, thereby stabilizing the pressure of the gas when it is discharged and achieving precise control of the gas pressure.

[0052] Furthermore, see Figure 2-Figure 6 The buffer component 40 includes a buffer disk 42 and a clamping disk 41. The diameter of the buffer disk 42 is larger than the diameter of the first air inlet 13, and the diameter of the clamping disk 41 is larger than the diameter of the buffer disk 42. The buffer component mounting portion 22 is provided with a clamping space 43 and a clamping protrusion 44. The clamping protrusion 44 is provided on the wall of the clamping space 43. The buffer component 40 is installed in the clamping space 43, and the clamping disk 41 is fixed against the clamping protrusion 44.

[0053] The buffer component mounting portion 22 is provided with a clamping space 43 and a clamping protrusion 44. The diameter of the clamping disc 41 is larger than the diameter of the buffer disc 42 and is fixed against the clamping protrusion 44. This clamping structure enables the buffer component 40 to be firmly mounted in the buffer component mounting portion 22. During the long-term operation of the solenoid valve 100, the buffer component 40 will not be easily displaced or loosened, ensuring its reliability and stability in the action of closing the first air inlet end. At the same time, the provision of the clamping space 43 and the clamping protrusion 44 makes the installation of the buffer component 40 relatively simple, without the need for other complicated connection methods.

[0054] Also, see Figure 2-Figure 6 The ventilation groove 21 includes a U-shaped opening 211 and a ventilation hole 212 , one end of the ventilation hole 212 is connected to the U-shaped opening 211 , and the other end of the ventilation hole 212 is connected to the nozzle 30 .

[0055] By providing the U-shaped opening 211 and the vent hole 212 , the U-shaped opening 211 is on the outside, and when the gas enters the U-shaped opening 211 through the vent hole 212 , the air resistance encountered is reduced, thereby increasing the flow rate of the entire solenoid valve.

[0056] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
