Description

Technical Field

[0001] This utility model belongs to the field of turbocharger technology, specifically relating to an adjustable-angle turbocharger. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] During actual assembly, the engine turbocharger needs to be installed in conjunction with the expansion joint, exhaust pipe, and rigid pipe connection structure. Some features of the expansion joint have specific angle adjustment requirements. Only by properly adjusting the angle can the precise fit between the turbocharger and the expansion joint, exhaust pipe, and rigid pipe be ensured, thereby guaranteeing the connection stability and operational coordination of the entire assembly system.

[0004] Under current technological conditions, meeting the aforementioned angle adjustment requirements typically requires disassembling and adjusting the turbocharger. However, this operation presents certain problems. Unauthorized disassembly and adjustment can easily damage critical performance parameters of the turbocharger, such as bolt torque. Bolt torque is a core indicator ensuring the connection strength, sealing performance, and power transmission efficiency of turbocharger components. Once damaged, it will directly lead to performance impairment of the turbocharger, specifically manifested as decreased boost efficiency, failure of seals between components, abnormal vibration or noise during operation, and in severe cases, even damage to the internal structure of the turbocharger, affecting its normal service life and further impacting the overall reliability and safety of the engine.

[0005] If the turbocharger is left unadjusted to avoid performance damage from disassembly and adjustment, then other methods must be used to meet the assembly and compatibility requirements: on the one hand, the machining accuracy of mating parts such as expansion joints, exhaust pipes, and rigid pipes needs to be significantly improved, increasing the difficulty and cost of parts production; on the other hand, the overall design scheme related to the engine turbocharger also needs to be adjusted, extending the design cycle. Utility Model Content

[0006] To address the aforementioned issues, this utility model provides an adjustable-angle booster. By engaging the volute groove with the flange protrusion, and connecting the flange to the volute end intermediate body, angle adjustment can be achieved without disassembly, avoiding damage to parameters such as bolt torque, and adapting to components such as expansion joints. The pressure plate limits the axial movement of the flange without hindering rotation, ensuring smooth adjustment.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable-angle turbocharger includes a turbocharger pressure end, a turbocharger intermediate body, and a turbocharger scroll end. One end of the turbocharger pressure end is connected to one end of the turbocharger intermediate body, and the other end of the turbocharger intermediate body is connected to the turbocharger scroll end. The turbocharger scroll end includes a scroll housing and a scroll end intermediate body. A flange is provided on the inner side of the scroll housing. A plurality of protrusions are spaced apart on the outer ring of the flange. A plurality of slots are spaced apart on the inner wall surface of the scroll housing. The protrusions are installed in the slots to engage the scroll housing and the flange. There is a gap between the outer wall surface of the protrusion and the inner wall surface of the slot.

[0008] As a further technical solution, a pressure plate is provided on one side of the flange, and several pressure plates are arranged at intervals around the flange, with several threaded holes opened at intervals on the pressure plates.

[0009] As a further technical solution, threaded holes are provided on the side of the vortex housing, and several threaded holes are provided at intervals.

[0010] As a further technical solution, the threaded hole of the pressure plate is aligned with the threaded hole on the side of the volute, and the pressure plate and the volute are detachably connected by pressure plate bolts.

[0011] As a further technical solution, the upper part of the inner side of the pressure plate is in close contact with the side of the volute, and there is a gap between the lower part of the inner side of the pressure plate and the flange.

[0012] As a further technical solution, the flange is provided with threaded holes, and the threaded holes are arranged at intervals.

[0013] As a further technical solution, optical holes are provided on the intermediate body of the vortex end, and several optical holes are provided at intervals.

[0014] As a further technical solution, the threaded hole on the vortex end intermediate body is aligned with the threaded hole on the flange, and the vortex end intermediate body and the flange are detachably connected by intermediate body bolts.

[0015] As a further technical solution, one end of the turbocharger intermediate body is detachably connected to one end of the turbocharger intermediate body, thereby realizing the detachable connection between the turbocharger turbocharger and the turbocharger intermediate body.

[0016] As a further technical solution, the other end of the turbocharger intermediate body is detachably connected to the turbocharger pressure end.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are: The turbocharger's turbine housing has a groove on its inner wall. Protrusions spaced at intervals on the outer ring of the flange fit into the groove, forming a movable fit, with a pre-existing gap between the protrusions and the inner wall of the groove. Simultaneously, the flange is fastened to the turbine housing's intermediate body via bolts, forming a synchronously moving unit. During angle adjustment, the flange drives the turbine housing's intermediate body to rotate circumferentially around the turbocharger's core axis relative to the turbine housing. The gap between the protrusions and the groove provides the space for rotation. Through the structural fit between the turbine housing, flange, and turbine housing's intermediate body, non-destructive adjustment of the turbocharger's angle is achieved, effectively avoiding damage to key performance parameters such as bolt torque caused by disassembly. It can precisely adapt to the angle requirements of the expansion joint, exhaust pipe, and rigid pipe connection structure, ensuring accurate docking between the turbocharger and its mating components, thereby maintaining the connection stability of the assembly system.

[0018] The pressure plate of this utility model provides stable support for angle adjustment through a specific fit with the volute and flange. The pressure plate is spaced around the flange and is detachably connected to the side of the volute by pressure plate bolts. The upper inner part of the pressure plate is in close contact with the side of the volute, and a small gap is reserved between the lower inner part of the pressure plate and the flange. This allows the pressure plate to apply continuous axial pressure to the flange, restricting the flange's movement in the axial direction and avoiding axial gaps between the flange and the volute and the volute end intermediate body during angle adjustment. At the same time, the small gap design does not hinder the circumferential rotation of the flange, ensuring smooth angle adjustment.

[0020] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0021] Under current technological conditions, meeting the aforementioned angle adjustment requirements typically requires disassembling and adjusting the turbocharger. However, this operation presents certain problems. Unauthorized disassembly and adjustment can easily damage critical performance parameters of the turbocharger, such as bolt torque. Bolt torque is a core indicator ensuring the connection strength, sealing performance, and power transmission efficiency of turbocharger components. Once damaged, it will directly lead to performance impairment of the turbocharger, specifically manifested as decreased boost efficiency, failure of seals between components, abnormal vibration or noise during operation, and in severe cases, even damage to the internal structure of the turbocharger, affecting its normal service life and further impacting the overall reliability and safety of the engine.

[0022] If the turbocharger is left unadjusted to avoid performance damage from disassembly and adjustment, then other methods must be used to meet the assembly and compatibility requirements: on the one hand, the machining accuracy of mating parts such as expansion joints, exhaust pipes, and rigid pipes needs to be significantly improved, increasing the difficulty and cost of parts production; on the other hand, the overall design scheme related to the engine turbocharger also needs to be adjusted, extending the design cycle.

[0023] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses an adjustable-angle booster, such as... Figure 1 As shown, it includes a turbocharger pressure end 7, a turbocharger intermediate body 8, and a turbocharger scroll end 9. One end of the turbocharger pressure end 7 is connected to one end of the turbocharger intermediate body 8, and the other end of the turbocharger intermediate body 8 is connected to the turbocharger scroll end 9, as shown. Figure 2 and Figure 3 As shown, the turbocharger volute 9 includes a volute housing 6 and a volute intermediate body 3. A flange 5 is provided on the inner side of the volute housing 6. Several protrusions 10 are provided at intervals on the outer ring of the flange 5. Several slots 11 are provided at intervals on the inner wall surface of the volute housing 6. The protrusions 10 are installed in the slots 11 to engage the volute housing 6 and the flange 5. There is a gap between the outer wall surface of the protrusions 10 and the inner wall surface of the slots 11.

[0024] Specifically, the inner wall of the turbine housing 6 of the turbocharger turbine tip 9 is provided with a groove 11. The flange 5 has protrusions 10 spaced apart on its outer ring that fit into the groove 11, forming a movable fit. A gap is reserved between the protrusions 10 and the inner wall of the groove 11. Simultaneously, the flange 5 is fastened to the turbine tip intermediate body 3 via intermediate bolts 4, forming a synchronously moving unit. During angle adjustment, the flange 5 can drive the turbine tip intermediate body 3 to rotate circumferentially relative to the turbine housing 6 around the turbocharger's core axis. The gap between the protrusions 10 and the groove 11 provides the space for rotation.

[0025] Through the structural cooperation of the volute housing 6, flange 5 and volute end intermediate body 3, the angle of the turbocharger can be adjusted without damage. This effectively avoids the problem of damage to key performance parameters such as bolt torque caused by disassembly. It can accurately adapt to the angle requirements of the expansion joint, exhaust pipe and hard pipe plug structure, and ensure the precise docking of the turbocharger and each mating component, thereby maintaining the connection stability of the assembly system.

[0026] Specifically, the turbocharger pressure end 7 is detachably connected to one end of the turbocharger intermediate body 8. Its main function is to draw in fresh air and compress it, delivering high-density intake air to the engine cylinders, providing a basis for complete fuel combustion, thereby ensuring the engine's power output and combustion efficiency. At the same time, the detachable connection with the turbocharger intermediate body 8 facilitates subsequent inspection and maintenance of the pressure end or other turbocharger components.

[0027] The turbocharger scroll end 9 is a key component for the installation of the turbocharger with the expansion joint and exhaust pipe. It includes structures such as the scroll housing 6 and the scroll end intermediate body 3. It is detachably connected to one end of the turbocharger intermediate body 8 through the scroll end intermediate body 3, thus completing the assembly with the turbocharger as a whole. The turbocharger scroll end 9 is used to receive the exhaust gas from the engine, and its angle can be adjusted through its own structure to meet the assembly angle requirements of components such as the expansion joint, ensuring precise fit between the turbocharger and all mating components.

[0028] When adjustments are needed, first ensure that the flange 5 and the turbine intermediate body 3 are securely connected by the intermediate body bolts 4, and that the turbine intermediate body 3 and the turbocharger intermediate body 8, and the turbocharger intermediate body 8 and the turbocharger pressure end 7 are all detachably connected. During adjustment, because the outer ring protrusion 10 of the flange 5 is embedded in the groove 11 of the turbine housing 6 and there is a gap between them, the flange 5 can be pushed to drive the turbine intermediate body 3 to rotate circumferentially relative to the turbine housing 6 until the required angle for matching the expansion joint and exhaust pipe is achieved. The entire process does not require disassembling the core components of the turbocharger, thus avoiding damage to key parameters such as bolt torque.

[0029] A pressure plate 2 is provided on one side of the flange 5, with several pressure plates 2 spaced around the flange 5 and several threaded holes spaced on the pressure plate 2. Threaded holes are also provided on the side of the volute 6, with several threaded holes spaced apart. The threaded holes of the pressure plate 2 are aligned with the threaded holes on the side of the volute 6, and the pressure plate 2 and the volute 6 are detachably connected by pressure plate bolts 1. The upper part of the inner side of the pressure plate 2 is in close contact with the side of the volute 6, while there is a gap between the lower part of the inner side of the pressure plate 2 and the flange 5.

[0030] Specifically, the pressure plate 2 provides stable support for angle adjustment through a specific fit with the volute housing 6 and the flange 5. The pressure plate 2 is spaced around the flange 5 and is detachably connected to the side of the volute housing 6 by the pressure plate bolts 1. The upper inner part of the pressure plate 2 is in close contact with the side of the volute housing 6, and a small gap is reserved between the lower inner part and the flange 5. This allows the pressure plate 2 to apply continuous axial pressure to the flange 5, restricting the movement of the flange 5 in the axial direction and avoiding axial gaps between the flange 5 and the volute housing 6 and the intermediate body 3 of the volute end during the angle adjustment process. At the same time, the small gap design does not hinder the circumferential rotation of the flange 5, ensuring smooth angle adjustment.

[0031] The flange 5 is provided with threaded holes, which are spaced at intervals. The scroll end intermediate body 3 is provided with smooth holes, which are also spaced at intervals. The threaded holes on the scroll end intermediate body 3 are aligned with the threaded holes on the flange 5, and the scroll end intermediate body 3 and the flange 5 are detachably connected by intermediate body bolts 4.

[0032] Specifically, when assembling the flange 5 and the scroll end intermediate body 3, first align the threaded holes spaced apart on the flange 5 with the smooth holes spaced apart on the scroll end intermediate body 3, ensuring that each threaded hole is precisely aligned with its corresponding smooth hole. Then, pass the intermediate body bolts 4 through the smooth holes of the scroll end intermediate body 3 and screw them into the threaded holes of the flange 5 until the bolts are tightened, thus connecting the flange 5 and the scroll end intermediate body 3.

[0033] When maintenance is required on the flange 5 or the vortex end intermediate body 3, the intermediate body bolts 4 can be unscrewed to separate the two. At the same time, the precise alignment of the holes can prevent relative misalignment after the flange 5 and the vortex end intermediate body 3 are connected, ensuring that the flange 5 can stably drive the vortex end intermediate body 3 to move synchronously during subsequent angle adjustments.

[0034] One end of the turbocharger intermediate body 3 is detachably connected to one end of the turbocharger intermediate body 8, thereby achieving a detachable connection between the turbocharger turbocharger 9 and the turbocharger intermediate body 8. The other end of the turbocharger intermediate body 8 is detachably connected to the turbocharger pressure end 7.

[0035] Specifically, when assembling the turbocharger scroll end 9 and the turbocharger intermediate body 8, one end of the scroll end intermediate body 3 is detachably connected to one end of the turbocharger intermediate body 8, so that the turbocharger scroll end 9 and the turbocharger intermediate body 8 form a stable assembly through the scroll end intermediate body 3. If the turbocharger scroll end 9 or the turbocharger intermediate body 8 needs to be inspected or repaired later, this connection structure can be disassembled to separate the two. The other end of the turbocharger intermediate body 8 is detachably connected to the turbocharger pressure end 7, completing the overall assembly of the turbocharger pressure end 7, the turbocharger intermediate body 8, and the turbocharger scroll end 9.

[0036] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
