Description

Technical Field

[0001] This utility model relates to a turbocharger connector, specifically a two-section tie rod and crank combination turbocharger connector. Background Technology

[0002] For various precision connecting transmission rod assemblies, such as the connecting parts between the electronic control actuator of an automotive turbocharger and the turbine housing end, they have properties such as high temperature resistance, high precision, and high wear resistance. In addition, the assembly position is generally subject to shape and spatial complexity constraints, and the structure also needs to meet requirements such as quick and easy fastening connection.

[0003] In existing turbochargers, the connection between the turbine housing and the electronically controlled actuator is generally a single-piece structure, which is heavy and complicated to assemble. The actuator also has noise issues during operation. Utility Model Content

[0004] This utility model proposes a two-stage turbocharger connector, which aims to overcome the above-mentioned shortcomings of the existing technology and solve the noise problem while ensuring precise connection and transmission.

[0005] The technical solution of this utility model is a two-section turbocharger connector, the structure of which includes an injection-molded tie rod and a stainless steel tie rod coaxially connected at one end. The other ends of the injection-molded tie rod and the stainless steel tie rod are respectively connected to the electronically controlled actuator and the turbine housing end of the automotive turbocharger through a crank assembly. The two-section structure can reduce the overall structural weight while meeting heat resistance requirements, and is easy to assemble.

[0006] Preferably, the crank assembly has a connection hole at the end not connected to the injection-molded tie rod and the stainless steel tie rod. This hole is used to connect the electronic actuator and the volute end.

[0007] Preferably, the other end of the injection-molded tie rod and the stainless steel tie rod are respectively rotatably connected to the corresponding crank assembly via a crank pin. This facilitates assembly and production.

[0008] Preferably, one end of the injection-molded tie rod is injection-molded to wrap around the other end of the stainless steel tie rod. This facilitates connection.

[0009] Preferably, a noise-reducing rubber sleeve is provided between the other end of the injection-molded tie rod and the crank pin. This achieves a noise reduction function.

[0010] The advantages of this utility model are: It features a reasonable structural design, replacing the existing one-piece stainless steel tie rod with a combination of a two-piece injection-molded tie rod and a stainless steel tie rod. Combined with the noise-reducing rubber sleeve, it achieves noise reduction while meeting the requirements of precision connection and transmission. The overall structure is compact and simple, easy to manufacture and assemble, and meets the durability requirements under high-temperature environments. It is suitable for scenarios with high precision, high wear resistance requirements, assembly position relative shape constraints, and complex spatial requirements. Attached Figure Description

[0015] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0016] like Figure 1-3 As shown, a two-stage turbocharger connector includes an injection-molded tie rod 4 and a stainless steel tie rod 5 coaxially connected at one end. The other ends of the injection-molded tie rod 4 and the stainless steel tie rod 5 are respectively connected to the electronic control actuator and the turbine housing end of the automobile turbocharger through a crank assembly 2.

[0017] The crank assembly 2 has a connection hole at one end, excluding the injection-molded tie rod 4 and the stainless steel tie rod 5. This hole is used to connect the assembled components, namely the electric actuator and the volute end.

[0018] The other ends of the injection-molded tie rod 4 and the stainless steel tie rod 5 are respectively rotatably connected to the corresponding crank assembly 2 via a crank pin 1.

[0019] The stainless steel pull rod 5 is the heat-resistant end, which can meet the heat resistance requirements. One end of the injection-molded pull rod 4 is injection-molded to wrap the other end of the stainless steel pull rod 5, so that they can be connected to each other.

[0020] A noise-reducing rubber sleeve 3 is provided between the other end of the injection-molded tie rod 4 and the crank pin 1. This enables noise reduction.

[0021] Based on the above structure, during specific processing, a connection hole is reserved at the end of the crank assembly 2 away from the tie rod, which can be conveniently connected to the assembled parts. The crank assembly 2 and the crank pin 1 are combined to form a connecting assembly. After the crank assembly 2 is installed with the vehicle body, the assembly with the crank pin 1 forms a ready-to-connect state, and it is connected with the corresponding connecting rod to form an integral connecting part.

[0022] All of the components described above are existing technologies, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0023] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
