Description

Technical Field

[0001] This utility model relates to the field of turbochargers, and in particular to a pressure shell structure for a turbocharger. Background Technology

[0002] The turbocharger is a key component for improving engine power. It cleverly uses the energy of the exhaust gas from the engine to drive the turbine to rotate at high speed. The turbine drives the compressor on the other side to operate synchronously through a rigid shaft. The compressor efficiently compresses fresh air and forces it into the engine cylinder, allowing more air to participate in combustion. This significantly increases power output without increasing engine displacement. This technology not only enhances the vehicle's power performance but also improves fuel efficiency.

[0003] The volute at the compressor end of a turbocharger is usually called the compressor housing. The surface of the compressor housing is usually equipped with a connector to connect a bypass line. One end of the bypass line connects to the flow channel inside the compressor housing, and the other end connects to a bypass valve, so that compressed air can be discharged when necessary. However, since the traditional bypass line is only fitted onto the output pipe of the connector and then fixed with Dacromet elastic clamps, it is prone to loosening during use or falling off due to accidents. The connector fixed on the compressor housing is also prone to loosening and leakage after long-term use. The current compressor housing structure is not convenient for monitoring the leakage at these two points.

[0004] Therefore, it is necessary to provide a new turbocharger housing structure to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a turbocharger pressure shell structure that can effectively monitor possible air leakage at the connection between the bypass pipeline and the output pipeline, as well as at the connection between the joint and the pressure shell.

[0006] To solve the above-mentioned technical problems, the present invention provides a turbocharger housing structure comprising: a housing body, a monitoring structure installed on the housing surface of the housing body, the monitoring structure including a cover, the bottom surface of the cover being fixedly connected to the outer surface of the housing body, a fixing pipe being fixedly connected to the bottom inner wall of the cover, a connector being installed on the surface of the fixing pipe, a top cover being installed on the top of the cover, and a bypass pipe being installed on one side wall surface of the cover;

[0007] A discharge pipe is fixedly connected to one side wall surface of the cover. The interior of the discharge pipe is connected to the interior of the cover. A pressure relief valve and a flow sensor are installed at one end of the discharge pipe. The input end of the pressure relief valve is fixedly connected to the end of the discharge pipe, and the input end of the flow sensor is fixedly connected to the output end of the pressure relief valve.

[0008] As a further embodiment of this utility model, the top cover is fitted onto the top of the housing and a sealing gasket is provided between the mating surfaces of the top cover and the housing. The top end face of the housing is provided with a plurality of equally spaced and evenly distributed mounting holes. The surface of the top cover is provided with through holes corresponding to the mounting holes. Mounting bolts are inserted into the through holes, and the mounting bolts are threaded into the mounting holes.

[0009] Through the above technical solution, in the traditional pressure shell structure, the connector is fixed to the shell surface, and the bypass pipe is sleeved on the output end of the connector and clamped by Dacromet elastic clamps. During vehicle operation, these two structures may sometimes loosen or fall off due to factors such as vehicle vibration or improper operation during maintenance, resulting in the airflow inside the pressure shell structure being directly discharged from these points and failing to enter the bypass valve of the turbocharger equipment. In order to monitor this situation, this device sets a cover on the outside of the connector. The top of the cover is firmly fixed and sealed by multiple sets of mounting bolts. The outside of the through hole on the cover for the bypass pipe to pass through is sealed by mounting rings, multiple sets of locking bolts, and PTFE gaskets, so that the internal space of the cover is in a sealed state. When high-pressure airflow leaks at the above two outlets, the airflow will be discharged from the pressure relief valve side and will be detected by the flow sensor. By receiving the data from the flow sensor, the user can promptly perceive the leakage.

[0010] As a further embodiment of this utility model, the interior of the fixed tube is connected to the internal flow channel of the pressure shell body, the fixed tube and the input end of the interface are threaded together, and a sealing ring is provided between the mating surfaces of the fixed tube and the input end of the interface.

[0011] With the above technical solution, the interface input end is fixed to the fixed pipe by a threaded connection, and a sealing ring is clamped between the two mating surfaces to improve its anti-leakage performance.

[0012] As a further embodiment of this utility model, the output end of the connector is fixedly connected to an output pipe, and one end of the bypass pipe is sleeved on the output pipe and located outside the output pipe. A Dacromet elastic clamp is installed on the surface of the bypass pipe, and the Dacromet elastic clamp is clamped on the surface of the bypass pipe.

[0013] The above technical solution utilizes Dacromet elastic clamps to clamp the bypass pipe onto the output pipe.

[0014] As a further embodiment of this utility model, a mounting base is fixedly connected to the side wall surface of the cover on the side of the discharge pipe. The surface of the mounting base is provided with a through hole, which penetrates the wall of the cover. One end of the bypass pipe extends through the through hole to the outside of the cover.

[0015] The purpose of the through hole in the structure described above is to allow the bypass pipe to pass through smoothly and connect to the bypass valve in the turbocharger.

[0016] As a further embodiment of this utility model, a PTFE collar is fitted on the surface of the bypass pipe located outside the housing. The inner wall of the PTFE collar is fixedly connected to the outer circumferential surface of the bypass pipe. An installation ring is fitted on the surface of the bypass pipe located on one side of the PTFE collar. The installation ring and the mounting seat are fixedly connected by a number of locking bolts arranged in a ring. The locking bolts penetrate the surface of the PTFE collar.

[0017] With the above technical solution, when the mounting ring is fixed to the mounting base by multiple sets of locking bolts, the PTFE collar is clamped between the mating surfaces of the two, thereby forming a sealing effect.

[0018] Compared with related technologies, the turbocharger housing structure provided by this utility model has the following advantages:

[0019] In traditional pressure shell structures, the connector is fixed to the shell surface, and the bypass pipe is fitted onto the connector output end and clamped using Dacromet elastic clamps. During vehicle operation, these two structures may loosen or fall off due to vehicle vibration or improper operation during maintenance, causing the airflow inside the pressure shell structure to be directly discharged from these points instead of entering the bypass valve of the turbocharger. To monitor this situation, this device has a cover installed on the outside of the connector. The top of the cover is firmly fixed and sealed by multiple sets of mounting bolts. The through hole on the cover for the bypass pipe is sealed on the outside using mounting rings, multiple sets of locking bolts, and PTFE gaskets, thus keeping the internal space of the cover sealed. When high-pressure airflow leaks at the two outlets, the airflow will be discharged from the pressure relief valve side and detected by the flow sensor. By receiving the data from the flow sensor, the user can promptly perceive the leakage. Attached Figure Description

Figure 2 ; Figure 4 This is a partial structural breakdown diagram of the pressure shell structure of a turbocharger according to this utility model. Figure 3 A turbocharger housing structure includes:

[0028] The pressure shell body 1 has a monitoring structure 2 installed on its shell surface. The monitoring structure 2 includes a cover 4. The bottom surface of the cover 4 is fixedly connected to the outer surface of the pressure shell body 1. A fixing pipe 18 is fixedly connected to the bottom inner wall of the cover 4. A connector 16 is installed on the surface of the fixing pipe 18. A top cover 5 is installed on the top of the cover 4. A bypass pipe 3 is installed on one side wall surface of the cover 4.

[0029] A discharge pipe 20 is fixedly connected to one side wall surface of the housing 4. The interior of the discharge pipe 20 is connected to the interior of the housing 4. A pressure relief valve 17 and a flow sensor 9 are provided at one end of the discharge pipe 20. The input end of the pressure relief valve 17 is fixedly connected to the end of the discharge pipe 20, and the input end of the flow sensor 9 is fixedly connected to the output end of the pressure relief valve 17.

[0030] like Figure 1-4As shown, the top cover 5 is fitted onto the top of the housing 4 and a sealing gasket 6 is provided between the mating surfaces of the top cover 5 and the housing 4. The top end face of the housing 4 is provided with several evenly spaced mounting holes 8. The surface of the top cover 5 is provided with through holes corresponding to the mounting holes 8. Mounting bolts 7 are inserted into the through holes, and the mounting bolts 7 and the mounting holes 8 are threaded together.

[0031] In a traditional pressure shell structure, connector 16 is fixed to the surface of the shell, and the bypass pipe is fitted onto the output end of connector 16 and clamped by Dacromet elastic clamp 11. During vehicle operation, these two structures may loosen or fall off due to vehicle vibration or improper operation during maintenance, causing the airflow inside the pressure shell structure to be discharged directly from there instead of entering the bypass valve of the turbocharger. To monitor this situation, a cover 4 is installed on the outside of connector 16. The top of cover 4 is firmly fixed and sealed by multiple sets of mounting bolts 7. The through hole on cover 4 through which the bypass pipe passes is sealed by mounting ring 12, multiple sets of locking bolts 13, and PTFE gaskets, thus keeping the internal space of cover 4 in a sealed state. When high-pressure airflow leaks at the two outlets, the airflow will be discharged from the pressure relief valve 17 and detected by flow sensor 9. By receiving the data from flow sensor 9, the user can promptly perceive the leakage.

[0032] like Figure 1-4 As shown, the interior of the fixed tube 18 is connected to the internal flow channel of the pressure shell body 1. The fixed tube 18 and the input end of the interface are threaded together. A sealing ring 19 is provided between the mating surfaces of the fixed tube 18 and the input end of the interface.

[0033] The interface input end is fixed to the fixed pipe 18 by a threaded connection, and a sealing ring 19 is clamped between the two mating surfaces to improve its leakage prevention performance.

[0034] like Figure 1-4 As shown, the output end of the connector 16 is fixedly connected to the output pipe 15. One end of the bypass pipe 3 is sleeved on the output pipe 15 and located outside the output pipe 15. The surface of the bypass pipe 3 is equipped with a Dacromet elastic clamp 11, which is clamped to the surface of the bypass pipe 3.

[0035] The Dacromet elastic clamp 11 allows the bypass pipe 3 to be clamped onto the output pipe 15.

[0036] like Figure 1-4 As shown, a mounting base 14 is fixedly connected to the side wall surface of the cover 4 on the side opposite to the discharge pipe 20. A through hole is opened on the surface of the mounting base 14, which penetrates the wall of the cover 4. One end of the bypass pipe 3 extends through the through hole to the outside of the cover 4.

[0037] The purpose of the through hole in this structure is to allow the bypass pipe 3 to pass smoothly through it, so that it can be connected to the bypass valve in the turbocharger equipment.

[0038] like Figure 1-4 As shown, a PTFE collar 10 is fitted on the surface of the bypass pipe 3 located outside the housing 4. The inner wall of the PTFE collar 10 is fixedly connected to the outer circumferential surface of the bypass pipe 3. An installation ring 12 is fitted on the surface of the bypass pipe 3 located on one side of the PTFE collar 10. The installation ring 12 and the mounting base 14 are fixedly connected by a number of locking bolts 13 arranged in a ring. The locking bolts 13 penetrate the surface of the PTFE collar 10.

[0039] When the mounting ring 12 is fixed to the mounting base 14 by multiple sets of locking bolts 13, the PTFE collar 10 is clamped between the mating surfaces of the two, thereby forming a sealing effect.

[0040] The working principle of the pressure shell structure of the turbocharger provided by this utility model is as follows:

[0041] In a traditional pressure shell structure, connector 16 is fixed to the surface of the shell, and the bypass pipe is fitted onto the output end of connector 16 and clamped by Dacromet elastic clamp 11. During vehicle operation, these two structures may loosen or fall off due to vehicle vibration or improper operation during maintenance, causing the airflow inside the pressure shell structure to be discharged directly from there instead of entering the bypass valve of the turbocharger. To monitor this situation, a cover 4 is installed on the outside of connector 16. The top of cover 4 is firmly fixed and sealed by multiple sets of mounting bolts 7. The through hole on cover 4 through which the bypass pipe passes is sealed by mounting ring 12, multiple sets of locking bolts 13, and PTFE gaskets, thus keeping the internal space of cover 4 in a sealed state. When high-pressure airflow leaks at the two outlets, the airflow will be discharged from the pressure relief valve 17 and detected by flow sensor 9. By receiving the data from flow sensor 9, the user can promptly perceive the leakage.
