Description

Technical Field

[0001] This utility model relates to turbochargers, and more particularly to a turbocharger volute housing. Background Technology

[0002] Currently, a turbocharger is essentially an air compressor that increases the intake air volume by compressing air. It utilizes the inertial force of the exhaust gases from the engine to drive a turbine within the turbine housing. The turbine, in turn, drives a coaxial impeller, which compresses the air supplied through the air filter, forcing it into the cylinders. As engine speed increases, the exhaust gas velocity and turbine speed also increase simultaneously. The impeller then compresses even more air into the cylinders. The increased air pressure and density allow for the combustion of more fuel. By correspondingly increasing the fuel quantity and adjusting the engine speed, the engine's output power can be increased.

[0003] However, existing volute components have limitations because they require the selection of appropriate specifications for casting based on the required air intake level. This means that if a single component malfunctions, the entire volute component must be replaced.

[0004] Therefore, in view of the shortcomings of the above-mentioned solutions in actual manufacturing and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created. It provides a turbocharger volute component structure to solve the problem that the existing volute components, which require the selection of appropriate specifications for casting according to different air intake levels, require the replacement of the entire volute component when a single component malfunctions, which is a limitation.

[0021] like Figure 1 , Figure 2 and Figure 5 As shown, a turbocharger housing includes a housing assembly 1, on which an exhaust pipe 102 is provided. The end face of the exhaust pipe 102 is provided with a connecting end face 103, as shown... Figure 6 As shown, a guide cylinder 3 is installed on the top of the housing assembly 1. In this embodiment, the guide cylinder 3 is welded to the housing assembly 1. In this embodiment, the guide cylinder 3 is an annular body. The guide cylinder 3 is covered by a cover 302, and the guide cylinder 3 and the cover 302 are detachably connected. A detachable guide cone is installed on the cover 302. The guide cone includes a connecting part 305 connected to the cover 302 and a conical ring 306 located below the connecting part 305. A partition 307 is installed inside the connecting part 305. Preferably, the partition 307 is a cross-shaped partition 307. Through the guide cone, the conical structure of the guide cone can stably guide and transport the airflow drawn in from the outside, thereby achieving a more practical purpose.

[0022] In this embodiment, as Figure 3 As shown, the cover 302 and the guide cone are detachably connected by threads. That is, an internal thread is provided on the inner wall of the central hole of the cover 302, while an external thread is provided on the guide cone. The guide cone and the cover 302 are connected by threads. During disassembly and installation, the cross-shaped partition 307 can be turned to realize the threaded disassembly and assembly of the guide cone and the cover 302.

[0023] In this embodiment, as Figure 1As shown, at least three guide grooves 301 are axially formed on the outer circumference of the top of the guide cylinder 3, and the guide grooves 301 extend downward along the axial direction. Preferably, there are four guide grooves 301, which are evenly distributed on the same circumference. A threaded hole is formed at the bottom of the guide groove 301. A guide post 308 corresponding to the guide groove 301 is provided on the inner side of the cover 302. A threaded through hole is formed on the guide post 308, and the threaded through hole extends upward along the axial direction and penetrates the cover 302. The guide post 308 is fitted into the corresponding guide groove 301, and the cover 302 and the guide cylinder 3 are connected by the threaded through hole and the threaded through hole. The positioning screw 304 in the hole is locked. During the installation of the cover 302, the cooperation between the guide post 308 and the guide groove 301 can ensure the installation accuracy of the guide cylinder 3 and the cover 302. The cover 302 and the guide cylinder 3 are finally locked by the positioning screw 304, thereby ensuring the reliability of the installation of the cover 302 and the guide cylinder 3. Furthermore, after the threaded through hole penetrates the cover 302, the hole on the cover 302 forms a positioning countersunk hole 303. When the locking screw is installed, the head of the locking screw is located in the positioning countersunk hole 303, so that the head of the locking screw does not protrude from the cover 302.

[0024] In this embodiment, as Figure 3 As shown, protruding guide blocks 309 are provided on both sides of the guide post 308, and grooves corresponding to the guide blocks 309 are opened on both sides of the guide groove 301. The guide blocks 309 slide in the guide groove. Through the cooperation between the guide blocks 309 and the guide groove, the installation accuracy of the cover 302 and the guide cylinder is further guaranteed.

[0025] In this embodiment, as Figure 4 As shown, a splicing mechanism 2 is installed inside the housing assembly 1. The splicing mechanism 2 includes a top plate and a bottom plate 203. The bottom plate 203 is located below the housing assembly 1, and the top plate is located inside the housing assembly 1. The top plate and the bottom plate 203 are locked together by a locking assembly 201. A bushing 204 is also provided on the top of the bottom plate 203, and the bushing 204 abuts against the top plate. In this embodiment, the housing assembly 1 includes an upper housing and a lower housing 101. The upper housing and the lower housing 101 are welded together. Before the upper housing and the lower housing 101 are welded together... Then the splicing mechanism 2 needs to be installed. Since the top plate and bottom plate 203 are connected by the locking assembly 201, both the bottom plate 203 and the lower housing 101 have through holes through which the locking assembly 201 passes. The screw of the locking assembly 201 is welded to the top plate. During installation, the screw is passed through the corresponding through hole, and then the nut 202 of the locking assembly 201 is tightened to realize the installation of the splicing assembly and the lower housing 101. After the splicing assembly is installed, the upper housing and the lower housing 101 are welded together.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
