Description

Technical Field

[0001] This utility model relates to the field of automotive automation technology, and in particular to an automotive transmission solenoid valve. Background Technology

[0002] Solenoid valves in automotive transmissions are core electro-hydraulic actuators in modern automatic transmissions, dual-clutch transmissions, and even some continuously variable transmissions (CVTs). They act as "switches" or "flow / pressure regulators," translating electronic commands from the transmission control unit into precise hydraulic actions to control the shifting process and other critical functions. When a solenoid valve is damaged, it can cause the transmission to fail to downshift, or result in shift delays or neutral engagements, posing safety hazards. Therefore, when a solenoid valve fails, multiple solenoid valves within the automotive transmission need to be inspected and repaired.

[0003] However, the current method of removing the solenoid valve from the transmission requires removing the bolts, which is cumbersome and time-consuming, affecting the efficiency of repairing or replacing the solenoid valve. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an automotive transmission solenoid valve.

[0005] This utility model provides an automotive transmission solenoid valve, comprising:

[0006] A valve body, wherein the axial direction of the valve body is a first direction, and one end of the valve body along the first direction is connected to a transmission housing;

[0007] The fixing mechanism includes a first fixing base disposed on the transmission housing, and a third sliding unit that can move along a second direction is provided inside the first fixing base. The end of the third sliding unit near the valve body is a fixing block.

[0008] The mounting mechanism includes a mounting base disposed on the side surface of the valve body and corresponding to the first fixing base. The mounting base has a third sliding groove for the fixing block to be inserted inside. The third sliding groove has a second sliding groove on both inner walls along the third direction. The second sliding groove has a second sliding unit that moves along the third direction. The second sliding unit has a first sliding groove on the side away from the fixing block. The first sliding groove has a first sliding unit that moves along the second direction. The first direction, the second direction and the third direction are perpendicular to each other.

[0009] When the fixed block moves along the second direction, the fixed block pushes the second sliding unit to move along the third direction into the first sliding groove; when the first sliding unit moves away from the valve body along the second direction, the first sliding unit pushes the second sliding unit to move along the third direction into the second sliding groove, and the first sliding unit is used to restrict the second sliding unit from moving away from the fixed block.

[0010] According to the technical solution provided in the embodiments of this application, the second sliding unit has a first inclined surface and a second inclined surface at one end near the third sliding unit. The first inclined surface forms a first angle with the inner wall of the third sliding groove, and the opening of the first angle faces the valve body. The second inclined surface forms a second angle with the inner wall of the third sliding groove, and the opening of the second angle faces the fixing mechanism.

[0011] According to the technical solution provided in the embodiments of this application, the second sliding groove is provided with a limiting groove at one end near the first sliding groove; the second sliding unit includes a locking block, and the locking block is provided with a limiting protrusion on the side away from the valve body. The limiting protrusion fits into the limiting groove, and the limiting protrusion and the limiting groove are used to restrict the second sliding unit from moving towards the side near the fixed block in a third direction.

[0012] According to the technical solution provided in the embodiments of this application, the first sliding unit includes a first sliding plate disposed in the first sliding groove. The first sliding plate has a third inclined surface, and the third inclined surface forms a third angle with the second sliding unit. The opening of the third angle faces the fixing mechanism. A first connecting plate is connected to the side of the two first sliding plates away from the transmission housing.

[0013] According to the technical solution provided in the embodiments of this application, the installation mechanism further includes a first fixing plate, which is disposed on one end face of the mounting base away from the transmission housing. The first fixing plate is located on the side of the first connecting plate away from the valve body, and along the first direction, the projection of the first fixing plate partially overlaps with the projection of the first sliding plate.

[0014] According to the technical solution provided in the embodiments of this application, the third sliding unit further includes a connecting rod disposed on one end face of the fixed block away from the valve body, the first fixed base is provided with a first through hole for the connecting rod to pass through on one end face of the valve body, and the other end of the connecting rod is connected to a second connecting plate.

[0015] According to the technical solution provided in the embodiments of this application, the transmission housing is further provided with a shock-absorbing mechanism, which is used to reduce the vibration of the mounting mechanism along the first direction and along the second direction.

[0016] According to the technical solution provided in the embodiments of this application, the shock-absorbing mechanism includes a second fixing plate disposed on the transmission housing. The second fixing plate is connected to the end face of the first fixing base away from the valve body. A second shock absorber is provided on the end face of the second fixing plate near the valve body. The other end of the second shock absorber is connected to the second connecting plate.

[0017] According to the technical solution provided in the embodiments of this application, the shock-absorbing mechanism further includes a second fixed base disposed on the transmission housing. The second fixed base is a U-shaped plate. A plurality of first shock absorbers are provided at the top of the inner wall of the second fixed base. A third connecting plate is connected to the other end of the first shock absorber. The end face of the third connecting plate away from the first shock absorber abuts against the first fixed plate.

[0018] According to the technical solution provided in the embodiments of this application, a rubber pad is also provided between the third connecting plate and the first fixing plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] When the solenoid valve needs to be installed, the third sliding unit is driven to slide towards the valve body, so that the fixing block is inserted into the third sliding groove and abuts against the second sliding unit. The fixing block pushes the second sliding unit to move away from the fixing block into the first sliding groove. Then the first sliding unit is driven to slide away from the valve body, so that the first sliding unit abuts against the second sliding unit and pushes the second sliding unit back into the second sliding groove, so that the second sliding unit locks the fixing block, and the installation is completed.

[0021] When the solenoid valve needs to be disassembled, the first sliding unit is driven to slide towards the valve body, so that the first sliding unit is no longer in contact with the second sliding unit. Then, the third sliding unit is driven to slide away from the valve body. The fixing block pushes the second sliding unit away from the fixing block and moves it into the first sliding groove, so that the fixing block is disassembled from the third sliding groove, completing the disassembly. Compared with bolts, this invention allows for faster installation or disassembly. In addition, compared with other technical fields that use springs to control the extension and retraction of the second sliding unit, this invention uses the first sliding unit to abut, achieving a more stable fixing effect and preventing the solenoid valve from being unstable due to the extension and retraction of the second sliding unit controlled by the spring, thus affecting the normal use of the solenoid valve.

[0022] This utility model also includes a shock-absorbing mechanism. The first and second shock absorbers in the shock-absorbing mechanism can effectively reduce the vibration of the valve body in the left-right and up-down directions, greatly improving the shock resistance of the battery valve and helping to prevent the solenoid valve from falling off during vehicle operation.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0038] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] Please refer to Figures 1-6 An embodiment of this utility model provides an automotive transmission solenoid valve, comprising:

[0040] Valve body 1, the axis of valve body 1 extends in a first direction, and one end of valve body 1 along the first direction is connected to transmission housing 5; the first direction is Figure 1 The vertical direction in the middle;

[0041] The fixing mechanism 3 includes a first fixing base 33 disposed on the transmission housing 5. The first fixing base 33 has a third sliding unit 31 that can move along a second direction inside it. The end of the third sliding unit 31 near the valve body 1 is a fixing block 311; the second direction is... Figure 1 The left and right directions in the middle;

[0042] The mounting mechanism 2 includes a mounting base 21 disposed on the side surface of the valve body 1 and corresponding to the first fixing base 33. The mounting base 21 has a third sliding groove 28 for inserting a fixing block 311. The third sliding groove 28 has two second sliding grooves 26 on its two inner walls along the third direction. Each second sliding groove 26 contains a second sliding unit 24 that moves along the third direction. The side of the second sliding unit 24 away from the fixing block 311 has a first sliding groove 27. Each first sliding groove 27 contains a first sliding unit 23 that moves along a second direction. The first direction, the second direction, and the third direction are perpendicular to each other. The third direction is... Figure 1 The front and back directions in the middle;

[0043] When the fixed block 311 moves along the second direction, the fixed block 311 pushes the second sliding unit 24 to move along the third direction into the first sliding groove 27; when the first sliding unit 23 moves along the second direction away from the valve body 1, the first sliding unit 23 pushes the second sliding unit 24 to move along the third direction into the second sliding groove 26, and the first sliding unit 23 is used to restrict the second sliding unit 24 from moving away from the fixed block 311.

[0044] like Figure 3 As shown, when the solenoid valve needs to be installed, the third sliding unit 31 is driven to slide towards the valve body 1, so that the fixing block 311 is inserted into the third sliding groove 28 and abuts against the second sliding unit 24. The fixing block 311 pushes the second sliding unit 24 to move away from the fixing block 311 into the first sliding groove 27. Then the first sliding unit 23 is driven to slide away from the valve body 1, so that the first sliding unit 23 abuts against the second sliding unit 24 and pushes the second sliding unit 24 back into the second sliding groove 26, so that the second sliding unit 24 locks the fixing block 311, and the installation is completed.

[0045] like Figure 6 As shown, when the solenoid valve needs to be disassembled, the first sliding unit 23 is driven to slide towards the valve body 1, so that the first sliding unit 23 is no longer in contact with the second sliding unit 24. Then, the third sliding unit 31 is driven to slide away from the valve body 1. The fixing block 311 pushes the second sliding unit 24 to move away from the fixing block 311 into the first sliding groove 27, so that the fixing block 311 is dislodged from the third sliding groove 28, and the disassembly is completed. This utility model can easily and quickly install or disassemble the solenoid valve, which greatly improves the maintenance speed.

[0046] In some embodiments, the second sliding unit 24 has a first inclined surface and a second inclined surface at one end near the third sliding unit 31. The first inclined surface forms a first angle with the inner wall of the third sliding groove 28, and the opening of the first angle faces the valve body 1. The second inclined surface forms a second angle with the inner wall of the third sliding groove 28, and the opening of the second angle faces the fixing mechanism 3.

[0047] like Figure 2 and Figure 3 As shown, when the fixed block 311 abuts against the first inclined surface, under the action of force, the second sliding unit 24 will move away from the fixed block 311, and the fixed block 311 can continue to move in the original direction; when the first sliding unit 23 abuts against the second sliding unit 24, under the action of force, the second sliding unit 24 will be pushed back into the second sliding groove 26 by the first sliding unit 23, thereby locking the fixed block 311 and completing the fixation; as Figure 6 As shown, when the fixed block 311 abuts against the second inclined surface, under the action of force, the second sliding unit 24 will move away from the fixed block 311. The fixed block 311 can continue to move in the original direction. At this time, the first sliding unit 23 is driven to slide towards the valve body 1, so that the second sliding unit 24 is not restricted by the first sliding unit 23. In this way, the fixed block 311 can be dislodged from the third sliding groove 28 and the disassembly is completed. This allows the solenoid valve to be installed quickly and can be fixed more stably, which is beneficial to improving the installation speed of the solenoid valve.

[0048] In some embodiments, the second sliding groove 26 is provided with a limiting groove at one end near the first sliding groove 27; the second sliding unit 24 includes a locking block 241, and the locking block 241 is provided with a limiting protrusion 242 on the side away from the valve body 1. The limiting protrusion 242 fits into the limiting groove, and the limiting protrusion 242 and the limiting groove are used to restrict the second sliding unit 24 from moving towards the side near the fixed block 311 in a third direction.

[0049] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the second sliding groove 26 and the limiting groove form an L-shaped groove. The limiting protrusion 242 of the second sliding unit 24 fits into the limiting groove. When the first sliding unit 23 pushes the second sliding unit 24 back into the second sliding groove 26, the second sliding unit 24 will not slide into the third sliding groove 28 due to the limitation of the limiting protrusion 242 and the limiting groove. This ensures that the fixing block 311 can be firmly fixed, thereby preventing the fixing mechanism 3 and the installation mechanism 2 from separating, thus preventing the normal use of the solenoid valve from being affected.

[0050] In some embodiments, the first sliding unit 23 includes a first sliding plate 231 disposed in the first sliding groove 27. The first sliding plate 231 has a third inclined surface, which forms a third angle with the second sliding unit 24. The opening of the third angle faces the fixing mechanism 3. The side of the two first sliding plates 231 away from the transmission housing 5 is connected to a first connecting plate 232.

[0051] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the third inclined surface of the first sliding plate 231 abuts against the second sliding unit 24. Under the action of force, the second sliding unit 24 will move towards the direction of the fixed block 311, which makes it easier for the second sliding unit 24 to lock the fixed block 311. The first connecting plate 232 can drive the sliding of the two first sliding plates 231 at the same time, which facilitates unified adjustment and makes it easier to install or disassemble the solenoid valve.

[0052] Furthermore, a first spring 22 is connected between the first sliding groove 27 and the first sliding plate 231. The first spring 22 can automatically push the first sliding unit 23 away from the valve body 1, which helps to reduce manual operation when driving the first sliding unit 23 to push the second sliding unit 24 back into the second sliding groove 26, making the operation more convenient.

[0053] In some embodiments, the mounting mechanism 2 further includes a first fixing plate 25, which is disposed on one end face of the mounting base 21 away from the transmission housing 5. The first fixing plate 25 is located on the side of the first connecting plate 232 away from the valve body 1, and the projection of the first fixing plate 25 coincides with the projection of the first sliding plate 231 along the first direction.

[0054] like Figure 2 and Figure 5 As shown, the first fixing plate 25 is provided with screw holes, and the mounting base 21 is provided with screw holes that correspond one-to-one with the first fixing plate 25. The first fixing plate 25 can be fixedly connected to the mounting base 21 by screws. From a top view, the projection of the first fixing plate 25 coincides with the projection of the first sliding plate 231. The first fixing plate 25 can effectively prevent the first sliding plate 231 from coming out of the first sliding groove 27 during the driving of the car, thereby causing the fixing block 311 to come out of the third sliding groove 28, thus preventing the normal use of the solenoid valve from being affected.

[0055] In some embodiments, the third sliding unit 31 further includes a connecting rod 312 disposed on one end face of the fixing block 311 away from the valve body 1, and the first fixing base 33 is provided with a first through hole near one end face of the valve body 1 for the connecting rod 312 to pass through, and the other end of the connecting rod 312 is connected to a second connecting plate 313.

[0056] like Figure 2 , Figure 3 and Figure 4 As shown, the first fixed base 33 is provided with a fourth sliding groove 32, and the third sliding unit 31 can move in the left and right direction in the fourth sliding groove 32; the setting of the fixed block 311, the connecting rod 312 and the second connecting plate 313 can ensure the fixed connection between the mounting mechanism 2 and the fixing mechanism 3, which is beneficial to the stable installation of the solenoid valve on the transmission housing 5.

[0057] In some embodiments, the transmission housing 5 is further provided with a shock-absorbing mechanism 4, which is used to reduce the vibration of the mounting mechanism 2 along the first direction and along the second direction.

[0058] like Figures 1-5 As shown, the shock-absorbing mechanism 4 can reduce the vibration of the mounting mechanism 2 in the vertical and horizontal directions, and can effectively prevent the solenoid valve from falling off during vehicle operation.

[0059] In some embodiments, the shock-absorbing mechanism 4 includes a second fixing plate 45 disposed on the transmission housing 5. The second fixing plate 45 is connected to the end face of the first fixing base 33 away from the valve body 1. A second shock absorber 46 is disposed on the end face of the second fixing plate 45 near the valve body 1. The other end of the second shock absorber 46 is connected to a second connecting plate 313.

[0060] like Figures 1-5As shown, the second fixing plate 45 is fixed to the transmission housing 5. A second shock absorber 46 is connected to one end face of the second fixing plate 45. The second shock absorber 46 is connected to the third sliding unit 31 and is located on the left and right sides of the valve body 1. The second shock absorber 46 can effectively reduce the vibration of the valve body 1 in the left and right directions, thereby making the valve body 1 more firmly fixed to the transmission housing 5 and preventing the solenoid valve from falling off during vehicle operation.

[0061] In some embodiments, the shock-absorbing mechanism 4 further includes a second fixed base 41 disposed on the transmission housing 5. The second fixed base 41 is a U-shaped plate. A plurality of first shock absorbers 42 are provided at the top of the inner wall of the second fixed base 41. A third connecting plate 43 is connected to the other end of the first shock absorber 42. The end face of the third connecting plate 43 away from the first shock absorber 42 abuts against the first fixed plate 25.

[0062] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a first shock absorber 42 is connected between the second fixed base 41 and the third connecting plate 43. The second fixed base 41 is a U-shaped plate, which facilitates the installation of the first shock absorber 42 on the upper side of the mounting mechanism 2. The third connecting plate 43 abuts against the first fixed plate 25. The first shock absorber 42 can effectively reduce the vibration of the valve body 1 in the vertical direction and prevent the solenoid valve from falling off during vehicle operation.

[0063] Furthermore, the first shock absorber 42 or the second shock absorber 46 can be a spring damper, which only needs to have the function of reducing vibration.

[0064] In some embodiments, a rubber pad 44 is further provided between the third connecting plate 43 and the first fixing plate 25.

[0065] like Figure 2 and Figure 4 As shown, the rubber pad 44 can further reduce the vibration of the valve body 1 in the vertical direction, which helps to increase the shock resistance of the anti-vibration mechanism 4 and further prevent the solenoid valve from falling off during vehicle operation.

[0066] When the solenoid valve needs to be installed, the third sliding unit 31 is driven to slide towards the valve body 1, so that the fixing block 311 is inserted into the third sliding groove 28 and abuts against the first inclined surface of the second sliding unit 24. The fixing block 311 pushes the second sliding unit 24 to move away from the fixing block 311 into the first sliding groove 27. Then the first sliding unit 23 is driven to slide away from the valve body 1, and the third inclined surface of the first sliding unit 23 abuts against the second sliding unit 24, thereby pushing the second sliding unit 24 back into the second sliding groove 26, so that the second sliding unit 24 locks the fixing block 311.

[0067] When the solenoid valve needs to be disassembled, the first sliding unit 23 is driven to slide towards the valve body 1, so that the first sliding unit 23 is no longer in contact with the second sliding unit 24. Then, the third sliding unit 31 is driven to slide away from the valve body 1, so that the fixing block 311 abuts against the second inclined surface. Under the action of force, the second sliding unit 24 will move into the first sliding groove 27, so that the fixing block 311 will be dislodged from the third sliding groove 28, and the disassembly is completed. This utility model can easily and quickly install or disassemble the solenoid valve, and can fix the solenoid valve more stably, which greatly improves the maintenance speed.

[0068] This utility model also includes a first shock absorber 42 and a second shock absorber 46, which can effectively alleviate the vibration of the valve body 1 in the left-right and up-down directions, greatly improve the shock resistance of the battery valve, and help prevent the solenoid valve from falling off during vehicle operation.
