Description

Technical Field

[0001] This utility model relates to the field of turbocharger technology, and in particular to a turbocharger exhaust bypass valve connection structure. Background Technology

[0002] A turbocharger is a device used to increase the amount of air entering an engine, primarily to improve engine power and efficiency. Its basic principle is to increase the intake air volume by compressing air, thereby allowing for more complete combustion of fuel and improving engine performance. The wastegate valve is an important component of the turbocharger; its main function is to bypass and discharge exhaust gas entering the turbocharger housing when the pressure is too high, reducing the turbocharger's workload and protecting it from excessive pressure.

[0003] Existing devices operate at high temperatures under heavy loads, making their structures susceptible to deformation due to material expansion. Furthermore, they lack stability when dealing with complex working environments (such as vibration and pressure changes). Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a connection structure for a turbocharger exhaust bypass valve.

[0005] This utility model is achieved using the following technical solution: a turbocharger exhaust bypass valve connection structure, including a lower connecting cylinder, a protective ring provided on the surface of the lower connecting cylinder, an upper connecting cylinder provided at the top of the lower connecting cylinder, a fixing block one provided on the surface of the lower connecting cylinder, a threaded hole one provided at the top of the fixing block one, a fixing block two provided on the surface of the lower connecting cylinder, a threaded hole two provided at the top of the fixing block two, a limit block one provided at the right end of the upper connecting cylinder, a connecting block one provided on the inner wall of the limit block one, and a connection block one provided inside the connecting block one. The connection includes bolts, a rotating shaft inside the first connecting block, a second connecting block on the surface of the rotating shaft, a connecting rod at the bottom of the second connecting block, a connecting ring at the bottom of the connecting rod, a valve handle at the bottom of the connecting ring, a support rod at the left end of the first connecting block, a nut at the bottom of the support rod, a support column at the bottom of the nut, a hydraulic spring on the surface of the support column, a limit block two at the bottom of the hydraulic spring, a fixing column at the bottom of the limit block two, and a base at the bottom of the fixing column.

[0006] As a further improvement to the above solution, the surface of the lower connecting cylinder is fixedly connected to the inner wall of the protective ring, the bottom end of the upper connecting cylinder contacts the bottom end of the lower connecting cylinder, the surface of the lower connecting cylinder is fixedly connected to the inner wall of the first fixing block, the surface of the upper connecting cylinder is fixedly connected to the inner wall of the first fixing block, two threaded holes are provided, the two threaded holes are opened at the top of the first fixing block, the surface of the upper connecting cylinder is fixedly connected to the inner wall of the second fixing block, and two threaded holes are provided, the two threaded holes are opened at the top of the second fixing block.

[0007] Through the above technical solution, the lower connecting cylinder, as part of the entire connection structure, provides a connection base for other parts. For example, it works with the upper connecting cylinder to jointly construct a connection channel or support structure. The protective ring directly protects the lower connecting cylinder, reducing the possibility of it being subjected to external physical damage or chemical corrosion, extending the service life of the lower connecting cylinder, thereby ensuring the stability of the entire connection structure. Together with the lower connecting cylinder and the upper connecting cylinder, they jointly construct a complete connection channel, ensuring smooth gas flow during the operation of the waste gas bypass valve.

[0008] As a further improvement to the above solution, the left end of the limiting block one is fixedly connected to the right end of the upper connecting cylinder, the surface of the bolt is threaded to the inner wall of the limiting block one, the surface of the bolt is driven to the inner wall of the connecting block one, the surface of the rotating shaft is driven to the inner wall of the connecting block one, and the inner wall of the connecting block two is driven to the surface of the rotating shaft.

[0009] Through the above technical solution, the limiting block 1 serves the functions of connection and limitation, restricting the movement range of components such as connecting block 1, and ensuring the stability and accuracy of the connection structure during operation. The bolts and rotating shaft inside connecting block 1 realize the transmission function, transmitting and converting the movement of each component. For example, the constraint of limiting block 1 is linked to the movement of connecting block 2, which is an important hub for the transmission and connection of movement in the entire structure. The rotating shaft surface is connected to the inner wall of connecting block 1 and connecting block 2 through transmission, serving as an intermediate motion transmission medium, transmitting the power of connecting block 1 to connecting block 2, so that the movement of the entire structure can proceed continuously.

[0010] As a further improvement to the above solution, the top end of the connecting rod is fixedly connected to the bottom end of the connecting block two, the bottom end of the connecting rod is fixedly connected to the top end of the connecting ring, and the bottom end of the connecting ring is fixedly connected to the top end of the valve handle.

[0011] Through the above technical solution, the top end is fixedly connected to the bottom end of the connecting block two, and the bottom end is fixedly connected to the top end of the connecting ring, so that the movement of the connecting block two is accurately transmitted to the connecting ring, thereby driving the valve handle to move and ensuring the accuracy of valve operation.

[0012] As a further improvement to the above solution, the left end of the connecting block is fixedly connected to the right end of the support rod, the bottom end of the support rod is fixedly connected to the top end of the nut, the top end of the support column is threadedly connected to the inner wall of the nut, and the top end of the hydraulic spring contacts the bottom end of the support rod.

[0013] Through the above technical solution, the right end of the support rod is fixedly connected to the left end of the connecting block 1, and the bottom end is fixedly connected to the top of the nut, which serves to support the connecting block 1. The nut is connected to the support column to ensure the stability of the connecting block 1 during operation. The top of the support column is threaded to the inner wall of the nut, and the bottom end is fixedly connected to the top of the chassis, providing vertical support for the entire structure and ensuring the stability of the structure during operation. Furthermore, the adjustment of the nut can adapt to different working conditions.

[0014] As a further improvement to the above solution, the top end of the second limiting block is fixedly connected to the bottom end of the hydraulic spring, and the bottom end of the second limiting block is fixedly connected to the top end of the fixed column.

[0015] Through the above technical solution, the top of the hydraulic spring contacts the bottom of the support rod, which plays a buffering role during the movement of the structure, absorbing part of the impact force. At the same time, it can reset the relevant components after the force disappears, ensuring the normal operation cycle of the structure. The top of the limiting block is fixedly connected to the bottom of the hydraulic spring, and the bottom is fixedly connected to the top of the fixed column, which limits the lower end of the hydraulic spring and connects the hydraulic spring to the fixed column to ensure the stability of the entire structure in the vertical direction.

[0016] As a further improvement to the above solution, the bottom end of the support column is fixedly connected to the top end of the chassis, and the top end of the chassis contacts the bottom end of the lower connecting cylinder.

[0017] Through the above technical solution, the fixed column fixes the limiting block 2 in a suitable position, thereby ensuring the normal working position of the hydraulic spring and playing an important role in the vertical support and stability of the entire structure. The chassis provides the bottom support foundation for the entire turbocharger exhaust bypass valve connection structure, ensuring the stability of the entire structure during operation.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This utility model provides a protective ring on the surface of the lower connecting cylinder, which can protect the lower connecting cylinder and reduce damage to the lower connecting cylinder from external factors, thereby improving the stability and service life of the entire connection structure. The upper connecting cylinder and the lower connecting cylinder are connected by fixing block one and fixing block two, and the fixing blocks are provided with threaded hole one and threaded hole two. This connection method makes the upper and lower connecting cylinders firmly connected, which can effectively prevent the connection from loosening during the operation of the booster and ensure the overall stability of the exhaust gas bypass valve connection structure.

[0020] The valve handle is connected to the upper connecting cylinder through components such as connecting ring, connecting rod, connecting block two, rotating shaft and connecting block one. This structural design makes the operation of the valve handle more flexible and facilitates the opening and closing of the waste gas bypass valve.

[0021] This utility model provides effective support for the entire connection structure through a support structure composed of a support rod, nut, support column, hydraulic spring, limit block two, and fixed column. The hydraulic spring acts as a buffer; when the vibration generated by the turbocharger is transmitted to the waste gas bypass valve connection structure, the hydraulic spring absorbs the vibration energy, reducing the impact of vibration on the connection structure and further protecting the various components within the connection structure. It also helps reduce noise generation. Attached Figure Description
