[0038] In the related art, during the manufacturing and assembly process of the traditional automobile steering intermediate shaft device, there will inevitably be an assembly gap between the inner and outer intermediate shaft bodies. The gap will change due to the action of various forces when the vehicle is driving normally, especially when the steering wheel is turning, and thus produce unnecessary vibration and noise.

The long-term existence of the assembly gap and the resulting vibration may cause increased wear of the steering system components, and may even cause safety hazards such as steering failure, posing a threat to the life safety of the driver and passengers.

[0039] Reference below Figure 1-Figure 8 A steering intermediate shaft assembly 1 according to an embodiment of the present invention is described.

[0040] like Figure 1-Figure 3 As shown, the steering intermediate shaft assembly 1 according to the utility model is used for a vehicle, and the steering intermediate shaft assembly 1 includes a first intermediate shaft 11, a second intermediate shaft 12, a force transmission member 13 and an elastic member 14. The first intermediate shaft 11 is formed with an accommodating cavity; a matching portion 121 is formed at one end of the second intermediate shaft 12, and the matching portion 121 is arranged in the accommodating cavity; the force transmission member 13 is arranged in the accommodating cavity, and the force transmission member 13 is constructed as a ring sleeved on the outer periphery of the matching portion 121 and is respectively matched with the first intermediate shaft 11 and the second intermediate shaft 12, so as to be suitable for transmitting torque between the first intermediate shaft 11 and the second intermediate shaft 12; the elastic member 14 is arranged on the force transmission member 13 and is suitable for generating an elastic force that makes the force transmission member 13 tightly match the first intermediate shaft 11 and the second intermediate shaft 12 respectively.

[0041] According to the steering intermediate shaft assembly 1 of the utility model, the matching portion 121 of the second intermediate shaft 12 is arranged in the accommodating cavity of the first intermediate shaft 11, thereby realizing the assembly of the first intermediate shaft 11 and the second intermediate shaft 12. By setting the force transmission member 13, the force transmission member 13 is arranged in the accommodating cavity, and is annularly sleeved on the outer periphery of the matching portion 121 of the second intermediate shaft 12, so that the force transmission member 13 can respectively cooperate with the first intermediate shaft 11 and the second intermediate shaft 12 to transmit torque between the first intermediate shaft 11 and the second intermediate shaft 12, thereby realizing the transmission of steering force. By setting the elastic member 14, the elastic member 14 is arranged on the force transmission member 13, and the elastic member 14 can play the role of filling and adjusting the gap, and can generate elastic force through its own elastic deformation, so that the force transmission member 13 is respectively tightly matched with the first intermediate shaft 11 and the second intermediate shaft 12, thereby reducing or eliminating the assembly gap between each other. When the driver turns the steering wheel, the steering force will be transmitted through the first intermediate shaft 11 and the second intermediate shaft 12. The force transmission member 13 is provided so that the torque can be transmitted between the first intermediate shaft 11 and the second intermediate shaft 12. The elastic force generated by the elastic member 14 can make the force transmission member 13 closely fit with the first intermediate shaft 11 and the second intermediate shaft 12, respectively, reduce the possibility of looseness, effectively reduce or eliminate the assembly gap, reduce unnecessary vibration and noise, not only improve driving comfort, but also help improve the steering performance of the vehicle, and even reduce the potential safety hazards caused by vibration and noise.

[0042] Therefore, according to the steering intermediate shaft assembly 1 of the present invention, by providing the force transmission member 13 and the elastic member 14, a close fit between the first intermediate shaft 11 and the second intermediate shaft 12 is achieved, thereby effectively reducing or eliminating the assembly gap, improving driving comfort and vehicle steering performance, and reducing safety hazards.

[0043] According to some embodiments of the present invention, Figure 3 , Figure 4 and Figure 8 As shown, the elastic member 14 is arranged between the first intermediate shaft 11 and the force transmission member 13, and the elastic member 14 is respectively formed with an adjustment portion 141 and a connecting portion 142 at both ends of the circumference of the force transmission member 13. The radial thickness of the elastic member 14 in the force transmission member 13 gradually decreases from the adjustment portion 141 to the connecting portion 142, and the adjustment portion 141 is suitable for being compressed and deformed under the pressure between the first intermediate shaft 11 and the force transmission member 13, and the connecting portion 142 is cooperatively connected with the force transmission member 13. By arranging the elastic member 14 between the first intermediate shaft 11 and the force transmission member 13, the elastic member 14 will be subjected to the pressure between the first intermediate shaft 11 and the force transmission member 13, thereby being compressed and deformed to generate elastic force, so that the first intermediate shaft 11 and the second intermediate shaft 12 are closely matched, and the surface of the force transmission member 13 matching with the first intermediate shaft 11 is close to the outer peripheral edge of the steering intermediate shaft assembly 1, and the space between the first intermediate shaft 11 and the force transmission member 13 is sufficient. The elastic member 14 is arranged between the first intermediate shaft 11 and the force transmission member 13 to fully utilize the space to reduce or eliminate the assembly gap. The elastic member 14 is formed with an adjustment portion 141 and a connection portion 142 at both ends of the circumferential direction of the force transmission member 13, respectively. The adjustment portion 141 can be compressed and deformed under the pressure between the first intermediate shaft 11 and the force transmission member 13; the connection portion 142 is responsible for matching and connecting with the force transmission member 13 to fix the position of the elastic member 14, so that the elastic member 14 can effectively generate elastic force and play a role. The radial thickness of the elastic member 14 in the force transmission member 13 gradually decreases from the adjustment portion 141 to the connection portion 142, so that when the elastic member 14 is subjected to radial pressure from the first intermediate shaft 11, the adjustment portion 141 can be compressed and deformed toward the connection portion 142, thereby effectively absorbing the pressure and generating corresponding elastic force, thereby filling and adjusting the gap, reducing unnecessary vibration and noise, and improving driving comfort.

[0044] According to some embodiments of the present invention, Figure 8 As shown, the cross-sectional shape of the adjustment portion 141 is configured as an arc. By configuring the cross-sectional shape of the adjustment portion 141 as an arc, the adjustment portion 141 can evenly disperse stress when subjected to pressure, thereby avoiding local stress concentration. In addition, the elasticity of the adjustment portion 141 can be improved, so that the adjustment portion 141 can be more easily deformed when subjected to pressure, thereby adapting to different working conditions. In addition, the arc-shaped cross-sectional shape also has high structural strength and stability, which enables the adjustment portion 141 to maintain stable performance during long-term use.

[0045] According to some embodiments of the present invention, Figure 3 , Figure 5 and Figure 7As shown, a first force transmission tooth 131 extending in the radial direction is formed on the surface of the force transmission member 13 that cooperates with the first intermediate shaft 11. The first force transmission tooth 131 is configured to be a plurality of teeth arranged at intervals in the circumferential direction. A plurality of first tooth grooves 111 corresponding to and cooperating with the first force transmission teeth 131 are formed on the inner circumferential wall of the first intermediate shaft 11. An accommodating gap 131a is defined between two adjacent first force transmission teeth 131. The elastic member 14 is configured to be a plurality of teeth and each elastic member 14 is correspondingly arranged in an accommodating gap 131a. The first force transmission teeth 131 of the force transmission member 13 cooperate with the first tooth grooves 111 of the first intermediate shaft 11, thereby realizing the cooperation and torque transmission between the force transmission member 13 and the first intermediate shaft 11. At the same time, there are a plurality of first force transmission teeth 131 arranged at intervals in the circumferential direction, and each first force transmission tooth 131 will match a first tooth groove 111, so the first tooth grooves 111 on the first intermediate shaft 11 are a plurality of first force transmission teeth 131 that match one by one, which helps to improve the accuracy and stability of the matching between the force transmission member 13 and the first intermediate shaft 11, so that when the force transmission member 13 transmits torque, the force transmission member 13 can more evenly distribute the force to each first force transmission tooth 131, thereby enhancing the structural strength of the force transmission member 13. At the same time, since the first force transmission teeth 131 are arranged at intervals, the accommodation gap 131a formed between two adjacent first force transmission teeth 131 provides space for the arrangement of the elastic member 14, so that the elastic member 14 can be arranged in the accommodation gap 131a, playing the role of filling and adjusting the gap. By constructing the elastic member 14 into multiple pieces, each elastic member 14 corresponds to an accommodation gap 131a and is arranged in the corresponding accommodation gap 131a, so that each elastic member 14 can independently play an elastic role, compensate and adjust a specific assembly gap, and improve the assembly accuracy and performance stability of the entire steering intermediate shaft assembly 1. When subjected to pressure, each elastic member 14 can be appropriately deformed and adjusted according to the position and force conditions, ensuring a tight fit between the force transmission member 13 and the first intermediate shaft 11.

[0046] According to some embodiments of the present invention, Figure 3 and Figure 4As shown, the adjustment parts 141 of two adjacent elastic members 14 are adjacent to each other, or the connection parts 142 of two adjacent elastic members 14 are adjacent to each other. In two adjacent elastic members 14, either the respective adjustment parts 141 are adjacent, or the respective connection parts 142 are adjacent. Specifically, in the arrangement of multiple elastic members 14, every two adjacent elastic members 14 will form a group. In each group, the two elastic members 14 can be arranged in a manner that the adjustment parts 141 are adjacent to each other, then the two adjacent elastic members 14 between the two groups are adjacent to each other in the connection parts 142; in each group, the two elastic members 14 can also be arranged in a manner that the connection parts 142 are adjacent to each other, then the two adjacent elastic members 14 between the two groups are adjacent to each other in the adjustment parts 141. When the steering intermediate shaft assembly 1 rotates clockwise, one elastic member 14 in each group can be compressed and deformed in the clockwise direction under the pressure of the first intermediate shaft 11; and when the steering intermediate shaft assembly 1 rotates counterclockwise, another elastic member 14 in each group can be compressed and deformed in the counterclockwise direction under the pressure of the first intermediate shaft 11; the elastic member 14 can be adaptively compressed and deformed according to the rotation direction of the steering intermediate shaft assembly 1, thereby effectively filling and adjusting the gap to adapt to the gap change during the rotation process, thereby effectively reducing the vibration and noise caused by the gap change, thereby improving the driving comfort and safety.

[0047] According to some embodiments of the present invention, Figure 3 , Figure 6 and Figure 7As shown, the second transmission teeth 132 extending in the radial direction are formed on the surface of the transmission member 13 that cooperates with the second intermediate shaft 12. The second transmission teeth 132 are configured to be arranged in a plurality at intervals in the circumferential direction. The outer peripheral wall of the second intermediate shaft 12 is formed with a plurality of second tooth grooves 122 corresponding to the second transmission teeth 132. Two adjacent second transmission teeth 132 define an oil storage gap 132a between the transmission member 13 and the second intermediate shaft 12. The oil storage gap 132a is used to accommodate lubricating oil. The second transmission teeth 132 extending in the radial direction are formed on the surface of the transmission member 13 that cooperates with the second intermediate shaft 12. The plurality of second transmission teeth 132 are arranged in a circumferentially spaced manner. At the same time, the outer peripheral wall of the second intermediate shaft 12 is formed with a plurality of second tooth grooves 122 corresponding to the second transmission teeth 132. The cooperation between the second transmission teeth 132 and the second tooth grooves 122 realizes the cooperation and torque transmission between the transmission member 13 and the second intermediate shaft 12, and the design of multiple second transmission teeth 132 arranged at intervals in the circumferential direction enables the force to be more evenly distributed to each second transmission tooth 132, thereby enhancing the overall structural strength of the transmission member 13. An oil storage gap 132a can be formed between two adjacent second transmission teeth 132, and the oil storage gap 132a can accommodate lubricating oil, so that the lubricating oil can be effectively stored in the oil storage gap 132a, thereby realizing the lubrication of the steering intermediate shaft assembly 1, reducing friction loss and wear, and extending the service life of the steering intermediate shaft assembly 1.

[0048] According to some embodiments of the present invention, Figure 3 and Figure 7 As shown, a plurality of first force transmission teeth 131 and a plurality of second force transmission teeth 132 are arranged in a one-to-one correspondence in the radial direction of the force transmission member 13. In the radial direction of the force transmission member 13, each first force transmission tooth 131 has a corresponding second force transmission tooth 132. The first force transmission teeth 131 and the corresponding second force transmission teeth 132 are at the same radial position of the force transmission member 13, which helps to ensure that the torque can be smoothly and evenly transmitted between the force transmission member 13 and the first intermediate shaft 11 and the second intermediate shaft 12. Each first force transmission tooth 131 can be closely matched with the corresponding second force transmission tooth 132 to form a continuous and stable torque transmission path, and also make the structure of the steering intermediate shaft assembly 1 more compact and stable. It should be noted that the one-to-one corresponding arrangement does not mean that the first force transmission teeth 131 and the second force transmission teeth 132 must be exactly the same in shape and size. The first force transmission teeth 131 and the second force transmission teeth 132 only need to be matched in the radial direction of the force transmission member 13. The specific shape and size may need to be selected and adjusted according to actual design requirements and performance requirements.

[0049] According to some embodiments of the present invention, Figure 3 , Figure 7 and Figure 8As shown, the force transmission member 13 is formed with a mounting hole 133, and a limiting pin 1421 is provided on the connecting portion 142. The limiting pin 1421 is arranged in the mounting hole 133 so that the connecting portion 142 is connected to the force transmission member 13. The mounting hole 133 formed on the force transmission member 13 cooperates with the limiting pin 1421 on the connecting portion 142 to achieve a stable connection between the elastic member 14 and the force transmission member 13. The limiting pin 1421 is arranged in the mounting hole 133 to limit the relative movement between the elastic member 14 and the force transmission member 13, thereby ensuring stability and reliability. Through the cooperation between the limiting pin 1421 and the mounting hole 133, the connection between the elastic member 14 and the force transmission member 13 is quick and convenient, which improves the assembly efficiency, and also reduces the manufacturing cost and maintenance difficulty.

[0050] According to some embodiments of the present invention, Figure 7 and Figure 8 As shown, the mounting holes 133 are configured to be multiple and spaced apart in the axial direction of the force transmission member 13, and the stop pins 1421 on the elastic member 14 are configured to be multiple and correspond to the mounting holes 133 one by one and are respectively arranged in each mounting hole 133. By configuring the mounting holes 133 to be multiple, more connection points can be provided, thereby enhancing the stability of the connection. Each stop pin 1421 on the elastic member 14 corresponds to a mounting hole 133 on the force transmission member 13, and the number and position of the stop pins 1421 and the mounting holes 133 are matched. Each stop pin 1421 is arranged in the mounting hole 133 corresponding thereto, thereby realizing the connection between the elastic member 14 and the force transmission member 13. Multiple mounting holes 133 are spaced apart in the axial direction of the force transmission member 13, which can effectively disperse the force, and the connection between the force transmission member 13 and the elastic member 14 is more uniform, adapting to the force requirements in different directions, reducing the structural stress concentration, and further enhancing the stability of the connection.

[0051] According to some embodiments of the utility model, the first intermediate shaft 11 and the second intermediate shaft 12 can move relative to each other in the axial direction. When the second intermediate shaft 12 is installed with the steering gear, the first intermediate shaft 11 and the second intermediate shaft 12 move relative to each other in the axial direction, and the length of the steering intermediate shaft assembly 1 can be adjusted to meet the installation requirements. When installing the steering gear, the first intermediate shaft 1 and the second intermediate shaft 12 can flexibly move relative to each other in the axial direction, thereby adjusting the length of the steering intermediate shaft assembly 1, enhancing the adaptability and flexibility of the steering intermediate shaft assembly 1, and enabling the steering intermediate shaft assembly 1 to easily adapt to different installation environments and requirements. By controlling the relative movement distance between the first intermediate shaft 1 and the second intermediate shaft 12, it can be ensured that the length of the steering intermediate shaft assembly 1 matches the installation size of the steering gear, thereby improving the assembly accuracy and stability of the entire steering system, and also simplifying the installation process, reducing the difficulty of installation, and improving work efficiency.

[0052] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the steering intermediate shaft assembly 1 further includes a dust cover 15, which is sleeved on the outer circumference of the first intermediate shaft 11 and is suitable for closing the gap between the first intermediate shaft 11 and the second intermediate shaft 12. By providing the dust cover 15, the dust cover 15 can close the gap between the first intermediate shaft 11 and the second intermediate shaft 12, effectively preventing foreign matter from entering the steering intermediate shaft assembly 1, and protecting the components in the steering intermediate shaft assembly 1 from damage. In addition, the dust cover 15 can also play a role of limiting, limiting the components in the steering intermediate shaft assembly 1 from escaping from the gap between the first intermediate shaft 11 and the second intermediate shaft 12, thereby improving reliability.
