[0021] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] This utility model embodiment provides a steering clamshell device, comprising: Upper clam shell assembly 1, wherein the upper clam shell assembly 1 is bent at a first angle on a first plane; The lower shell assembly 2 is connected and communicates with the upper shell assembly 1. The lower shell assembly 2 is bent at a second angle on a second plane, and the first plane intersects with the second plane.

[0023] It should be noted that when there is a large deviation between the engine exhaust end and the central axis of the three-way catalytic converter assembly, or when there is a three-dimensional spatial rotation, multiple castings with different structures are usually required for assembly. In this application, the upper shell assembly 1 and the lower shell assembly 2 are designed as follows: Figure 1 and Figure 2 As shown, since the upper shell assembly 1 is bent at a first angle on the first plane and the lower shell assembly 2 is bent at a second angle on the second plane, and the first plane intersects with the second plane, the upper shell assembly 1 and the lower shell assembly 2 can achieve a three-dimensional spatial rotation mechanism. The structure is simple and compact. This application can replace most casting structures. Compared with heavy castings, this structure effectively reduces the process production cost, facilitates on-site assembly, and is suitable for various special car models with complex peripheral gaps and compact structural space.

[0024] Furthermore, the first plane intersects the second plane at a 90° angle.

[0025] Furthermore, the upper shell assembly 1 includes: A first upper housing 11, wherein a first through hole 1a is provided on the first upper housing 11; The second upper housing 12 is disposed opposite to the first upper housing 11, and the first upper housing 11 and / or the second upper housing 12 are bent at a first angle on a first plane.

[0026] In a specific embodiment, such as Figure 1 and Figure 3 As shown, the upper shell assembly 1 is divided into a first upper shell 11 and a second upper shell 12, which is beneficial for on-site assembly. The first through hole 1a is used to connect the waste recycling pipe (EGR pipe).

[0027] Furthermore, the first upper housing 11 and / or the second upper housing 12 include a first flange, and the width between the first flanges is 5~7mm; And / or, the connection between the first upper housing 11 and the second upper housing 12 is a full weld.

[0028] This application adopts a full welding method. Compared with welding methods such as electric welding, full welding forms an integral structure through full-area fusion, ensuring the sealing between the first upper shell 11 and the second upper shell 12. During welding, the weld seam is spaced 6mm from the flange, which can avoid thermal deformation between the first upper shell 11 and the second upper shell 12 during welding, ensuring that the structure of the upper shell assembly 1 remains intact.

[0029] Furthermore, the second upper housing 12 is provided with a clearance groove 1b. The clearance groove 1b is used to avoid the installation sleeve tool of the air intake flange 4, which facilitates on-site installation.

[0030] Furthermore, the lower shell assembly 2 includes: A first lower shell 21 is provided with an annular portion at one end near the upper shell assembly 1, and the annular portion is fixedly connected to the upper shell assembly 1; The second lower housing 22 is disposed opposite to the first lower housing 21, and the second lower housing 22 is provided with a second through hole 2a.

[0031] In a specific embodiment, such as Figure 1 and Figure 4 As shown, configuring the lower shell assembly 2 as a first lower shell 21 and a second lower shell 22 facilitates on-site assembly. The annular portion facilitates the merging of the first upper shell 11 and the second upper shell 12, improving the sealing between the lower shell assembly 2 and the upper shell assembly 1. The second through hole 2a is used to install a sensor mounting base.

[0032] In this application, the number, position, shape, and size of the first through hole 1a and the second through hole 2a are not limited. The number, position, shape, and size of the first through hole 1a and the second through hole 2a can be adaptively adjusted according to actual needs. In a specific embodiment, the diameter of the first through hole 1a is 20~30mm. And / or, the diameter of the second through hole 2a is 20~25mm.

[0033] Furthermore, the first lower housing 21 and / or the second lower housing 22 include a second flange, the width of which is 5~7mm; And / or, the connection between the first lower housing 21 and the second lower housing 22 is a full weld.

[0034] During installation, the first upper shell 11 and the second upper shell 12 are fully welded together to obtain the upper shell assembly 1. Then, the first lower shell 21 and the second lower shell 22 are fully welded together to obtain the lower shell assembly 2. Finally, the upper shell assembly 1 and the lower shell assembly 2 are combined and installed on the tooling assembly fixture for welding connection, thus completing the installation of the steering shell device.

[0035] Furthermore, the first upper housing 11 is also provided with a first platform portion 1c, and the second lower housing 22 is provided with a second platform portion 2b. The steering clamshell device also includes a mounting bracket 3, one end of which is fixedly connected to the first platform part 1c and the other end of which is fixedly connected to the second platform part 2b.

[0036] In a specific embodiment, such as Figure 1 , Figure 3 , Figure 4As shown, the mounting bracket 3 is used to install the heat insulation cover. One end of the mounting bracket 3 is welded to the first platform part 1c, and the other end is welded to the second platform part 2b. The first platform part 1c and the second platform part 2b adopt a platform structure, which can increase their contact area with the mounting bracket 3, ensure a firm weld, avoid the mounting bracket 3 from shifting or tilting, and improve the safety of the steering clamshell device.

[0037] Furthermore, it also includes: An air inlet flange 4 is located at one end of the upper shell assembly 1 away from the lower shell assembly 2 and is fixedly connected to the upper shell assembly 1. The air inlet flange 4 is also provided with several mounting holes 4a. End cap 5 is disposed at the end of the lower shell assembly 2 away from the upper shell assembly 1 and is fixedly connected to the lower shell assembly 2. The cross-sectional area of ​​the end cap 5 gradually increases from the end near the lower shell assembly 2 to the end away from the lower shell assembly 2. The diameter of the end cap 5, which is furthest from the lower clam shell assembly 2, is 132-136 mm.

[0038] It should be noted that the structure of the intake flange 4 is not limited, and the shape of the intake flange 4 can be adapted to meet actual needs. The mounting hole 4a on the intake flange 4 is used to connect engine components.

[0039] The end cap 5 is used to connect the air outlet cylinder body. The end cap 5 and the lower shell assembly 2 can be integrally formed or can be set separately and welded together.
