Technical Field
[0001] This application relates to the field of steering gear technology, and more particularly to a split steering gear assembly. Background Technology
[0002] The steering gear is the core component of a vehicle's steering system. It is responsible for converting the rotation of the steering wheel into the steering action of the wheels, which directly affects the driving feel and safety.
[0003] Existing steering gear housings are typically formed as a single piece using a mold, resulting in a large mold size and difficulty in achieving stable molding, which can easily lead to defective products. Therefore, this application proposes a split steering gear assembly. Utility Model Content

[0005] To achieve the above objectives, this application adopts the following technical solution: a split steering gear assembly, including an aluminum housing and a cylinder housing, wherein the outer edge of the aluminum housing is connected to one end of two pipes, and the other end of the two pipes is connected to the cylinder housing, a connecting block is fixedly installed on the outer edge of the aluminum housing, an insertion hole is opened on the inner wall of the connecting block, a insertion pipe is inserted into the inner wall of the insertion hole, a positioning block is fixedly installed on the outer edge of the insertion pipe, two slots are opened on the inner wall of the positioning block, and the two pipes are inserted into the inner wall of the two slots, and an interference fit is provided between the aluminum housing and the cylinder housing.
[0006] In a preferred embodiment, a mounting block is fixedly installed on the outer edge of the cylinder housing, and a through hole is formed on the inner wall of the mounting block.
[0007] By adopting the above technical solution, bolts can be inserted into the inner wall of the through hole, thereby connecting the bolts to the frame and realizing the connection between the cylinder housing and the frame.
[0008] In a preferred embodiment, a frame is welded and installed on the outer edge of the cylinder housing. A round tube is fixedly installed inside the frame. The outer ring of a bearing is fixedly connected to the inner wall of the frame. Buffer pads are installed on both sides of the bearing.
[0009] By adopting the above technical solution, it can be used to connect the frame and ensure stable rotation. The buffer pad can effectively buffer the friction during rotation, further ensuring the stability during operation and the smoothness of rotation.
[0010] In a preferred embodiment, a second frame is welded to the outer edge of the aluminum shell, and bearings are also installed on the inner wall of the second frame.
[0011] By adopting the above technical solution, the aluminum shell can be easily connected to the frame, ensuring the stability of the connection.
[0012] In a preferred embodiment, the cylinder housing is equipped with a riveting recessed strip, and the outer edge of the aluminum housing is provided with a groove, and the riveting recessed strip is adapted to be snapped into the inner wall of the groove.
[0013] By adopting the above technical solution, the aluminum housing and the cylinder housing can be easily spliced and assembled, and the interference fit can ensure the stability of the aluminum housing and the cylinder housing after assembly.
[0014] In a preferred embodiment, the positioning block is made of rubber, and the width of the openings of the two slots is smaller than the diameter of the pipe.
[0015] By adopting the above technical solution, two pipes can be snapped into the inside of two slots. The elastic properties of the positioning block rubber material can be used to position the two pipes, ensuring that they can be stably set inside the two slots and will not swing around or rub against the aluminum shell, cylinder shell and frame.
[0016] The beneficial effects of this application are:
[0017] This type of split steering gear assembly is produced by a split molding process. Two molds are used to cast the aluminum housing and cylinder housing of the steering gear, respectively. The aluminum housing and the pipes are stably connected to each other through an interference fit and a riveting structure. This improves the stability of the steering gear assembly production and reduces the production of defective products. It can also reduce casting costs while maintaining the sealing of the aluminum housing and cylinder housing of the steering gear.
[0018] This split-type steering gear assembly uses two pipes to be pressed and snapped into the interior of two slots to position the two pipes, ensuring that they are stably installed inside the two slots and will not swing around or rub against the aluminum housing, cylinder housing and frame, thereby ensuring the service life of the pipes.

[0025] Reference Figure 1-4 A split steering gear assembly includes an aluminum housing 1 and a cylinder housing 2. The outer edge of the aluminum housing 1 is connected to one end of two pipes 3, and the other end of the two pipes 3 is connected to the cylinder housing 2. A connecting block 4 is fixedly installed on the outer edge of the aluminum housing 1. An insertion hole 5 is opened on the inner wall of the connecting block 4. An insertion pipe 6 is inserted into the inner wall of the insertion hole 5. A positioning block 7 is fixedly installed on the outer edge of the insertion pipe 6. Two slots 8 are opened on the inner wall of the positioning block 7, and the two pipes 3 are inserted into the inner wall of the two slots 8. An interference fit 16 is provided between the aluminum housing 1 and the cylinder housing 2.
[0026] See Figure 1 - Figure 3 An mounting block 9 is fixedly installed on the outer edge of the cylinder housing 2. A through hole 10 is provided on the inner wall of the mounting block 9, so that bolts can be inserted into the inner wall of the through hole 10, thereby connecting the bolts to the frame and realizing the connection between the cylinder housing 2 and the frame.
[0027] See Figure 3 and Figure 4 A frame 11 is welded and installed on the outer edge of the cylinder housing 2. A round tube 12 is fixedly installed inside the frame 11. The outer ring of the bearing 13 is fixedly connected to the inner wall of the frame 11. Buffer pads 14 are installed on both sides of the bearing 13, which can be used to connect to the frame and ensure stable rotation. The buffer pads 14 can effectively buffer the friction during rotation, further ensuring the stability and smoothness of operation.

The interference fit 16 can ensure the stability of the aluminum housing 1 and the cylinder housing 2 after assembly.
[0030] See Figure 1 and Figure 2 The positioning block 7 is made of rubber, and the opening width of the two slots 8 is smaller than the diameter of the pipe 3, so that the two pipes 3 can be snapped into the inside of the two slots 8. In addition, the elasticity of the rubber material of the positioning block 7 can be used to position the two pipes 3, ensuring that they can be stably set inside the two slots 8 and will not swing randomly and rub against the aluminum shell 1, the cylinder shell 2 and the frame.
[0031] Working principle: First, aluminum housing 1 and cylinder housing 2 can be taken separately. The riveting recessed strip on the inner wall of cylinder housing 2 can be inserted into the groove on the outer edge of aluminum housing 1 to achieve splicing between aluminum housing 1 and cylinder housing 2. Then, the insertion pipe 6 can be inserted into the inner wall of insertion hole 5 and connected to the inner wall of insertion pipe 6 and the frame by bolt thread. At the same time, the two pipes 3 can be pressed and snapped into the inside of the two slots 8 for positioning the two pipes 3. Then, frame one 11 and frame two 15 can be connected to the frame by bolts to achieve the installation of aluminum housing 1 and cylinder housing 2.
