Description

Technical Field

[0001] This utility model relates to the field of exhaust gas bypass valve technology, specifically to a mounting bracket for a booster exhaust gas bypass valve. Background Technology

[0002] The turbocharger wastegate valve is a key control component in a turbocharged engine. Its core function is to precisely regulate the boost pressure generated by the turbocharger, preventing excessive boost pressure in the engine under specific operating conditions, thereby protecting the engine and turbocharger itself, and optimizing engine performance and response.

[0003] Application number CN201220369866.6 discloses a turbocharger exhaust gas bypass valve connection structure, including an exhaust gas bypass valve assembly, a connecting rod, a connecting rod bearing, a turbine housing, and an actuator; the exhaust gas bypass valve assembly includes an exhaust gas bypass valve, a valve mounting plate, and a gasket; characterized in that: the exhaust gas bypass valve is sealed to the conical surface of the turbine housing; the exhaust gas bypass valve and the valve mounting plate are clearance-fitted, and the connecting rod bearing is interference-fitted onto the turbine housing; the connecting rod and the connecting rod bearing are clearance-fitted. The valve mounting plate is welded to one end of the connecting rod, and the other end of the connecting rod is welded to the actuator rod. The actuator rod and the connecting rod move in opposite linear directions. The connecting rod moves upward along the axis within the connecting rod bearing, opening the waste gas bypass valve. The connecting rod moves downward along the axis within the connecting rod bearing, closing the waste gas bypass valve. The clearance fit between the waste gas bypass valve and the valve mounting plate achieves automatic concentric alignment of the conical surface seal, ensuring good sealing performance. The conical columnar sealing surface is more suitable for controlling the opening degree of the waste gas bypass valve.

[0004] The waste gas bypass valve is fixedly connected to the connecting rod via a valve mounting plate, resulting in a rigid connection between the waste gas bypass valve and the connecting rod. When any component, such as the sealing surface of the waste gas bypass valve, wears or the connecting rod deforms and malfunctions, the damaged component cannot be replaced individually. Instead, the valve mounting plate, connecting rod, and related components must be replaced as a whole, which significantly increases maintenance costs and spare parts consumption. Therefore, a booster waste gas bypass valve mounting bracket is proposed. Utility Model Content

[0005] The main purpose of this utility model is to provide a mounting bracket for a turbocharger exhaust bypass valve, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A turbocharger exhaust gas bypass valve mounting bracket includes a bracket with a second sliding groove inside the bracket. A connecting plate is slidably mounted inside the second sliding groove. A first fixing plate and a second fixing plate are fixedly connected to both ends of the connecting plate, respectively. A first mounting groove is provided at the end of the first fixing plate away from the connecting plate. The first mounting groove is used for the second valve mounting plate to be inserted. The second valve mounting plate is fixedly sleeved on the upper outer side of the exhaust gas bypass valve body.

[0008] The second fixing plate has a second mounting groove at the end away from the connecting plate. The second mounting groove is used for inserting the plug. The plug is movably installed inside one end of the first valve mounting plate. The first valve mounting plate is fixedly sleeved on the upper outer side of the connecting rod.

[0009] By adopting the above technical solution and using modular mounting brackets, the waste gas bypass valve can be automatically locked upon insertion. When disassembling, the lock can be quickly released simply by pressing the push block or pushing the push rod. This allows the waste gas bypass valve body and connecting rod to be completely disassembled and maintained independently. When repairing or replacing a single component, it is not necessary to disassemble the entire mechanism, which significantly simplifies the operation process and reduces maintenance complexity and time costs.

[0010] Specifically, movable blocks are movably connected to both sides of the second valve mounting plate. One end of each movable block is fixedly connected to one end of the first spring, and the other end of the first spring is fixedly connected to the inner wall of the first spring cavity, which is located inside the second valve mounting plate.

[0011] Specifically, limiting blocks are fixedly connected to both sides of the inner side of the first mounting groove, and the limiting blocks are adapted to the movable blocks. Push blocks are movably installed on both sides of the first fixed plate.

[0012] By adopting the above technical solution, the limiting block, as a cooperating component of the locking structure, will exert a squeezing effect on the movable block when the second valve mounting plate is inserted into the first mounting groove, guiding the movable block to retract. When the second valve mounting plate is in place, the vertical surface of the limiting block will abut against the popped-out movable block to prevent the second valve mounting plate from falling out. When it is necessary to disassemble the waste gas bypass valve body, push the push blocks on both sides of the first fixing plate inward. The push blocks will squeeze the movable block, causing the movable block to overcome the elastic force of the first spring and retract into the first spring cavity, releasing the lock with the limiting block. At this time, the second valve mounting plate can be pulled out from the first mounting groove.

[0013] Specifically, one end of the insert block is fixedly connected to one end of the second spring, and the other end of the second spring is fixedly connected to the inner wall of the second spring cavity, which is located inside the first valve mounting plate.

[0014] By adopting the above technical solution, when the second fixing plate is aligned with the first valve mounting plate and the second mounting groove corresponds to the position of the insert block, the second spring is in a naturally extended state. Its elastic force will push the insert block out from the second spring cavity and insert it into the second mounting groove, thereby locking the first valve mounting plate and the second fixing plate. This structure ensures that the insert block always remains in an extended and locked state when not disassembled by the continuous action of the elastic force of the second spring, thus ensuring the stability of the connection between the connecting rod and the second fixing plate.

[0015] Specifically, a third sliding groove is provided on the top surface of the first valve mounting plate. The third sliding groove is used for sliding installation of the push rod, and the bottom end of the push rod is fixedly connected to the top end of the insert block.

[0016] By adopting the above technical solution, when it is necessary to disassemble the connecting rod or the first valve mounting plate, the push rod is pushed along the third slide groove. The push rod will drive the plug block fixedly connected to it to move synchronously. The plug block compresses the second spring and retracts into the second spring cavity. At this time, the plug block disengages from the second mounting groove, releases the lock between the first valve mounting plate and the second fixed plate, and can then separate the first valve mounting plate from the second fixed plate. The third slide groove provides guidance for the movement of the push rod, ensuring that the push rod drives the plug block to move smoothly.

[0017] Specifically, the second slide groove has a first slide groove on both sides, the first slide groove is used for the sliding installation of the ball bearings, and the ball bearings are rotatably installed on both sides of the connecting plate.

[0018] By adopting the above technical solution, when it is necessary to adjust the position of the first fixed plate and the second fixed plate, the connecting plate can slide in the second slide groove of the bracket. At this time, the balls on both sides of the connecting plate will roll in the first slide groove on both sides of the second slide groove, converting the sliding friction between the connecting plate and the second slide groove into rolling friction, reducing the resistance during relative movement, making the position adjustment of the first fixed plate and the second fixed plate smoother and easier, and facilitating quick alignment of the installation position.

[0019] The beneficial effects of this utility model are:

[0020] The present invention discloses a turbocharger waste gas bypass valve mounting bracket. Through the modular mounting bracket, the waste gas bypass valve is automatically locked upon insertion. During disassembly, the lock can be quickly released simply by pressing the push block or pushing the push rod. This allows the waste gas bypass valve body and connecting rod to be completely disassembled and maintained independently. When repairing or replacing a single component, it is not necessary to disassemble the entire mechanism, which significantly simplifies the operation process and reduces maintenance complexity and time costs.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] As one embodiment of this utility model, such as Figures 1-4 As shown, the present invention provides a turbocharger waste gas bypass valve mounting bracket, including a bracket 4. The bracket 4 has a second sliding groove 6 inside, and a connecting plate 3 is slidably installed inside the second sliding groove 6. A first fixing plate 8 and a second fixing plate 17 are respectively fixedly connected to both ends of the connecting plate 3. A first mounting groove 15 is provided at the end of the first fixing plate 8 away from the connecting plate 3. The first mounting groove 15 is used for the second valve mounting plate 9 to be installed and inserted. The second valve mounting plate 9 is fixedly sleeved on the upper outer side of the waste gas bypass valve body 10.

[0029] The second fixing plate 17 has a second mounting groove 18 at one end away from the connecting plate 3. The second mounting groove 18 is used for the insertion of the plug 14. The plug 14 is movably installed inside one end of the first valve mounting plate 2. The first valve mounting plate 2 is fixedly sleeved on the upper outer side of the connecting rod 1.

[0030] During use, when the second valve mounting plate 9 is inserted into the first mounting groove 15, the limiting block 21 in the first mounting groove 15 will squeeze the movable blocks 16 on both sides of the second valve mounting plate 9. After being forced, the movable blocks 16 retract into the first spring cavity 22, while compressing the first spring 23. When the second valve mounting plate 9 is fully inserted, the movable blocks 16 are no longer squeezed, and the first spring 23 restores its deformation and generates elastic force, pushing the movable blocks 16 out of the first spring cavity 22. At this time, the movable blocks 16 are engaged with the inner side of the limiting block 21, thereby locking the second valve mounting plate 9 in the first mounting groove 15, realizing the fixed connection between the waste gas bypass valve body 10 and the first fixed plate 8.

[0031] The present invention also includes movable blocks 16 movably connected to both sides of the second valve mounting plate 9. One end of the movable block 16 is fixedly connected to one end of the first spring 23, and the other end of the first spring 23 is fixedly connected to the inner wall of the first spring cavity 22. The first spring cavity 22 is located inside the second valve mounting plate 9.

[0032] The present invention also includes a limiting block 21 fixedly connected to the inner two sides of the first mounting groove 15, the limiting block 21 being adapted to the movable block 16, and a push block 11 being movably installed on both sides of the first fixing plate 8.

[0033] In use, the limiting block 21 acts as a cooperating component of the locking structure. When the second valve mounting plate 9 is inserted into the first mounting groove 15, it will exert a squeezing effect on the movable block 16, guiding the movable block 16 to retract. When the second valve mounting plate 9 is in place, the vertical surface of the limiting block 21 will abut against the popped-out movable block 16 to prevent the second valve mounting plate 9 from coming out. When it is necessary to disassemble the waste gas bypass valve body 10, push the push blocks 11 on both sides of the first fixing plate 8 inward. The push blocks 11 will squeeze the movable block 16, causing the movable block 16 to overcome the elastic force of the first spring 23 and retract into the first spring cavity 22, releasing the lock with the limiting block 21. At this time, the second valve mounting plate 9 can be pulled out from the first mounting groove 15.

[0034] The present invention further includes that one end of the insert block 14 is fixedly connected to one end of the second spring 20, and the other end of the second spring 20 is fixedly connected to the inner wall of the second spring cavity 19, wherein the second spring cavity 19 is disposed inside the first valve mounting plate 2.

[0035] When in use, when the second fixing plate 17 is aligned with the first valve mounting plate 2 and the second mounting groove 18 corresponds to the position of the insert 14, the second spring 20 is in a naturally extended state. Its elastic force will push the insert 14 out of the second spring cavity 19 and insert it into the second mounting groove 18, thereby locking the first valve mounting plate 2 and the second fixing plate 17. This structure ensures that the insert 14 always remains in the extended and locked state when not disassembled by the continuous action of the elastic force of the second spring 20, thus ensuring the stability of the connection between the connecting rod 1 and the second fixing plate 17.

[0036] The present invention also includes a third sliding groove 12 provided on the top surface of the first valve mounting plate 2, the third sliding groove 12 being used for sliding installation of the push rod 13, and the bottom end of the push rod 13 being fixedly connected to the top end of the insert block 14.

[0037] When in use, when it is necessary to disassemble the connecting rod 1 or the first valve mounting plate 2, push the push rod 13 along the third slide groove 12. The push rod 13 will drive the plug block 14 fixedly connected to it to move synchronously. The plug block 14 compresses the second spring 20 and retracts into the second spring cavity 19. At this time, the plug block 14 disengages from the second mounting groove 18, releases the lock between the first valve mounting plate 2 and the second fixing plate 17, and can then separate the first valve mounting plate 2 from the second fixing plate 17. The third slide groove 12 provides guidance for the movement of the push rod 13, ensuring that the push rod 13 drives the plug block 14 to move smoothly.

[0038] The present invention also includes a first slide groove 5 provided on both sides of the inner side of the second slide groove 6. The first slide groove 5 is used for sliding installation of the ball bearing 7. The ball bearing 7 is rotatably installed on both sides of the connecting plate 3.

[0039] When in use, when it is necessary to adjust the position of the first fixed plate 8 and the second fixed plate 17, the connecting plate 3 can slide in the second slide groove 6 of the bracket 4. At this time, the balls 7 on both sides of the connecting plate 3 will roll in the first slide groove 5 on both sides of the second slide groove 6, converting the sliding friction between the connecting plate 3 and the second slide groove 6 into rolling friction, reducing the resistance during relative movement, making the position adjustment of the first fixed plate 8 and the second fixed plate 17 smoother and easier, and facilitating quick alignment of the installation position.

[0040] In use and installation, the second valve mounting plate 9, which is fixed to the upper outer side of the exhaust bypass valve body 10, is inserted into the first mounting groove 15 of the first fixing plate 8 on the bracket 4. During insertion, the movable blocks 16 on both sides of the second valve mounting plate 9 are squeezed by the limiting blocks 21 in the first mounting groove 15, compressing the first spring 23 inside and retracting it. When the second valve mounting plate 9 is fully inserted, the movable block 16 pops out under the action of the spring force and is locked inside the limit block 21, forming a mechanical lock, thereby fixing the waste gas bypass valve body 10 on the first fixed plate 8. At the same time, the second fixed plate 17 slides up and down to align with the first valve mounting plate 2, so that the insert 14 inside extends out under the action of the second spring 20 and is inserted into the second mounting groove 18 of the second fixed plate 17. After the insert 14 enters the second mounting groove 18, it remains in the extended state, forming a lock, thereby fixing the connecting rod 1 on the second fixed plate 17 through the first valve mounting plate 2. In this way, the movement of the waste gas bypass valve body 10 is transmitted to the connecting rod 1 through the second valve mounting plate 9, the first fixed plate 8, the connecting plate 3, the second fixed plate 17, the insert 14, and the first valve mounting plate 2, realizing valve opening and closing control.

[0041] When maintenance is required, components can be disassembled independently: To replace the waste gas bypass valve body 10, push the push blocks 11 on both sides of the first fixed plate 8 to squeeze the movable block 16 so that it retracts against the force of the first spring 23 and disengages from the limit block 21, and the second valve mounting plate 9 can be pulled out from the first mounting groove 15. At this time, the connecting rod 1 does not need to be disassembled. To replace the connecting rod 1 or the first valve mounting plate 2, push the push rod 13 at the top of the first valve mounting plate 2 to drive the insert block 14 to retract against the force of the second spring 20 and disengage from the second mounting groove 18, and the first valve mounting plate 2 can be separated from the second fixed plate 17. At this time, the waste gas bypass valve does not need to be disassembled. This design achieves fast and reliable modular connection and independent disassembly through the spring locking mechanism, and allows relative displacement through the sliding mechanism, ultimately significantly reducing maintenance costs and spare parts consumption.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
