Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and more specifically, to an intermediate shaft assembly, a steering system, and a vehicle. Background Technology

[0002] In related technologies, multi-section intermediate shafts require dust covers for support. However, when the position of the intermediate shaft changes due to manufacturing tolerances and steering wheel adjustments, stress concentration can easily occur in this area, thus affecting the performance of the intermediate shaft. Utility Model Content

[0003] The purpose of this disclosure is to provide an intermediate shaft assembly, a steering system, and a vehicle, wherein the intermediate shaft and bearing components of the intermediate shaft assembly can swing within a housing to at least partially solve the aforementioned technical problems.

[0004] To achieve the above objectives, a first aspect of this disclosure provides an intermediate shaft assembly, comprising: a bracket including chambers extending through opposite sides of the bracket; a housing connected within the chambers; an intermediate shaft passing through the chambers and the housing; and a bearing member located within the chambers, wherein the inner ring of the bearing member is sleeved on the outside of the intermediate shaft for fixed connection to the intermediate shaft, and the outer ring of the bearing member is fixedly connected to the housing; wherein the intermediate shaft and the inner ring of the bearing member are rotatable about the axis of the intermediate shaft, and the intermediate shaft and the bearing member are oscillating relative to the housing. The bearing member and the housing are connected and can oscillate within the housing, thereby absorbing at least a portion of the force on the intermediate shaft within the bracket, reducing the force on the bearing member, or preventing the bearing member from being subjected to force, thus avoiding noise generation in the intermediate shaft assembly and extending the service life of the bearing member. Furthermore, this allows for flexible arrangement of the steering wheel angle adjustment axis, thereby improving the design flexibility of the steering column and the overall vehicle handling performance.

[0005] In some possible implementations, the housing is fixedly connected to the inner wall of the chamber and is arranged circumferentially along the chamber to form a receiving chamber capable of accommodating the bearing member and a portion of the intermediate shaft; when the bearing member and the intermediate shaft swing, the bearing member is located within the receiving chamber; and / or, a portion of the bearing member can be moved out of the receiving chamber. The housing's circumferential arrangement within the chamber maximizes its contact area with the outer ring of the bearing member, thereby ensuring the stability of the bearing member when it swings within the housing.

[0006] In some possible implementations, the outer ring of the bearing member includes a first connecting surface on the side facing away from the intermediate shaft, and the housing includes a second connecting surface on the side near the intermediate shaft that can mate with the first connecting surface, the second connecting surface covering at least a portion of the first connecting surface. The bearing member and the housing are connected by surface contact, which increases the connection area between them, allowing the bearing member to move stably on the second connecting surface via the first connecting surface, and ensuring that the intermediate shaft and the bearing member can swing together relative to the housing.

[0007] In some possible implementations, the first connecting surface and / or the second connecting surface comprises a sphere; wherein the center of the sphere is located on the axis of the intermediate shaft. The spherical arrangement can utilize the swing of the bearing within the housing, and due to the large connection area between the bearing and the housing, localized crushing or excessive wear between the bearing and the housing can be avoided.

[0008] In some possible implementations, the housing and the chamber are interference-fitted; and / or, the inner ring of the bearing is interference-fitted with the intermediate shaft. Using interference fits to connect the housing and the chamber, as well as the bearing and the intermediate shaft, ensures a tight connection, preventing relative movement between components.

[0009] In some possible implementations, the cavity has a limiting structure for restricting the movement of the housing along the extension direction of the cavity. The limiting structure ensures the stability of the connection between the housing and the cavity, preventing displacement of the intermediate shaft and bearing components within the cavity due to their oscillation within the housing, thereby also ensuring the stability of the connection between the bearing components and the housing.

[0010] In some possible implementations, the limiting structure is disposed on one side of the housing; alternatively, the limiting structure includes a first limiting member and a second limiting member spaced apart along the extension direction of the chamber, the first limiting member abutting against one side of the housing, and the second limiting member abutting against the opposite side of the housing. The limiting structure can simultaneously limit the housing from one or both sides to prevent movement of the housing within the chamber.

[0011] In some possible implementations, at least one of the first and second limiting members includes a protrusion extending toward the interior of the cavity. The protrusion can effectively limit the housing while maintaining a simplified internal cavity structure.

[0012] In some possible implementations, at least one of the first and second limiting members is provided in multiples, with the multiple first and / or multiple second limiting members arranged at circumferential intervals along the cavity. The provision of multiple limiting members can enhance the limiting effect of the limiting structure on the housing.

[0013] In some possible implementations, the housing includes a mating surface for connection with the front bulkhead of the vehicle, and a seal is provided on the mating surface. The seal ensures the airtightness of the housing after connection with the front bulkhead of the vehicle, thereby achieving a certain degree of sound insulation and preventing external impurities such as water and dust from entering the cavity.

[0014] A second aspect of this disclosure provides a steering system including the aforementioned intermediate shaft assembly.

[0015] A third aspect of this disclosure provides a vehicle including the aforementioned steering system.

[0016] Through the above technical solution, a bearing and a housing are sequentially arranged between the intermediate shaft and the bracket. The intermediate shaft is connected to the housing via the bearing, allowing it to rotate and swing within the housing. Therefore, when the intermediate shaft's position changes due to manufacturing tolerances of the vehicle or steering wheel adjustments, it can absorb at least a portion of the force on the intermediate shaft within the bracket, and reduce or eliminate the force on the bearing, thereby preventing noise from the intermediate shaft assembly and extending the service life of the bearing. Furthermore, this allows for flexible arrangement of the steering wheel angle adjustment shaft, improving the design flexibility of the steering column and the overall vehicle handling performance.

[0017] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0020] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0021] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to "inner" and "outer" relative to the contour of the corresponding component itself. Furthermore, the terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not imply sequentiality or importance. Additionally, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0022] The intermediate shaft assembly in the exemplary embodiments of this disclosure will now be described with reference to the accompanying drawings.

[0023] refer to Figures 1 to 5 As shown, in a first aspect of this disclosure, an intermediate shaft assembly is provided, including a support 1, a housing 2, an intermediate shaft 3, and a bearing 4. The support 1 includes a chamber 110 extending through opposite sides of the support 1. The housing 2 is connected within the chamber 110. The intermediate shaft 3 can pass through the chamber 110 and the housing 2. The bearing 4 is located within the chamber 110, with its inner ring 41 sleeved on the outside of the intermediate shaft 3 for fixed connection to the intermediate shaft 3, and its outer ring 42 fixedly connected to the housing 2. The intermediate shaft 3 and the inner ring 41 of the bearing 4 are rotatable about the axis of the intermediate shaft 3, and the intermediate shaft 3 and the bearing 4 are oscillating relative to the housing 2.

[0024] The intermediate shaft 3 is connected to the housing 2 in the chamber 110 via the bearing component 4. The housing 2 can provide certain support for the intermediate shaft 3 and has a certain dustproof effect. The bearing component 4 can reduce the rotational friction between the intermediate shaft 3 and the housing 2, thereby improving the rotation effect of the intermediate shaft 3. In addition, this setting can also reduce the noise generated by the intermediate shaft 3 when it rotates.

[0025] As the intermediate shaft 3 rotates, it drives the inner ring 41 of the bearing 4 to rotate together. The intermediate shaft 3 transmits the torque of the steering wheel to the vehicle's steering gear through its own rotational motion, thereby driving the tires to rotate and realizing the steering of the vehicle.

[0026] When the position of the intermediate shaft 3 changes due to manufacturing tolerances of the vehicle or steering wheel adjustment, the intermediate shaft 3 and bearing 4 can swing within the housing 2 to a certain extent. For example, when the chamber 110 is a circular chamber, there can be an angle between the central axis of the chamber 110 and the axis of the intermediate shaft 3. This can absorb at least part of the force on the intermediate shaft within the bracket 1, and reduce or prevent the force on the bearing 4, ensuring that the bearing 4 can work normally. This avoids noise from the intermediate shaft assembly and extends the service life of the bearing 4. In addition, this allows for flexible arrangement of the steering wheel angle adjustment rotation axis, thereby improving the design flexibility of the steering column and the handling performance of the entire vehicle.

[0027] Among them, the bearing component 4 can be a deep groove ball bearing. The steel ball located between the inner ring 41 and the outer ring 42 of the bearing component 4 can rotate when the intermediate shaft 3 and the inner ring 41 rotate. Thus, by converting sliding friction into rotational friction, the frictional torque is reduced. Compared with the plastic bearing structure used in related technologies, it has the advantages of low friction and low noise, and is less affected by environmental factors, which can ensure the service life of the bearing component 4.

[0028] In addition, bearing component 4 can also be selected from other types of bearings such as plastic bearings or needle roller bearings. This disclosure does not limit the specific type of bearing, as long as it can facilitate the rotation of the intermediate shaft 3 and swing together with the intermediate shaft 3 in the housing 2.

[0029] In embodiments of this disclosure, such as Figures 1 to 4 As shown, the housing 2 can be fixedly connected to the inner wall of the chamber 110 and is arranged circumferentially along the chamber 110 to form a receiving chamber 210 capable of accommodating the bearing 4 and a portion of the intermediate shaft 3; when the bearing 4 and the intermediate shaft 3 swing, the bearing 4 can be located within the receiving chamber 210; and / or, a portion of the bearing 4 can be moved out of the receiving chamber 210. The housing 2 is arranged circumferentially along the chamber 110 to maximize its contact area with the outer ring 42 of the bearing 4, thereby ensuring the stability of the bearing 4 when it swings within the housing 2.

[0030] After the position of the intermediate shaft 3 changes, the bearing component 4 and the intermediate shaft 3 can swing within the housing 2. Depending on the displacement of the intermediate shaft 3, the swing angle of the bearing component 4 and the intermediate shaft 3 will also change accordingly. When the intermediate shaft 3 moves only slightly, the swing angle of the intermediate shaft 3 and the bearing component 4 relative to the housing 2 is small. At this time, the bearing component 4 can still be located in the receiving chamber 210. However, when the displacement of the intermediate shaft 3 is large, the swing angle of the intermediate shaft 3 and the bearing component 4 relative to the housing 2 is large, which can cause part of the bearing component 4 to move out of the receiving chamber 210.

[0031] In addition, the area from which the bearing component 4 can be removed from the receiving chamber 210 should be a small part of the overall bearing component 4. This prevents the bearing component 4 from coming out of the housing 2 and ensures that the intermediate shaft 3 and the bearing component 4 can work normally.

[0032] In embodiments of this disclosure, such as Figure 1 and Figure 2 As shown, the outer ring 42 of the bearing component 4, on the side facing away from the intermediate shaft 3, may include a first connecting surface 43. The side of the housing 2 near the intermediate shaft 3 may include a second connecting surface 220 that can mate with the first connecting surface 43. The second connecting surface 220 covers at least a portion of the first connecting surface 43. That is, the bearing component 4 and the housing 2 are connected by surface contact, which can increase the connection area between them, thereby allowing the bearing component 4 to move stably on the second connecting surface 220 through the first connecting surface 43, and ensuring that the intermediate shaft 3 and the bearing component 4 can swing together relative to the housing 2.

[0033] Among them, such as Figure 1 and Figure 2 As shown, the first connecting surface 43 and / or the second connecting surface 220 include a spherical surface 100; wherein the center N of the spherical surface 100 is located on the axis of the intermediate shaft 3. The spherical surface 100 provides a certain curvature for both the first connecting surface 43 and the second connecting surface 220, allowing the bearing component 4 to swing within the housing 2. Furthermore, due to the large connection area between the bearing component 4 and the housing 2, the contact stress between them is relatively small, and the stress distribution is more uniform. This avoids localized crushing or excessive wear between the bearing component 4 and the housing 2.

[0034] The shell 2 can be constructed as a ring structure with a circular central opening. After the ring structure is placed in the chamber 110, a perpendicular line is drawn from the tangent M on a point on its inner wall. The intersection of this perpendicular line and the axis of the intermediate axis 3 is the aforementioned center N of the sphere.

[0035] With the center N of the sphere as the point and the first preset distance as the radius, a virtual sphere can be formed. The distance from the center N of the sphere to the outer side wall of the outer ring 42 of the bearing component 4 or the distance from the center N of the sphere to the inner side wall of the housing 2 is the first preset distance. It can also be understood that the plane where the first connecting surface 43 and the second connecting surface 220 meet is part of the virtual sphere.

[0036] In some possible implementations, such as Figure 1 and Figure 2 As shown, the housing 2 and the chamber 110 can be interference-fitted; and / or, the inner ring 41 of the bearing 4 and the intermediate shaft 3 can be interference-fitted. Using interference fits to connect the housing 2 and the chamber 110, as well as the bearing 4 and the intermediate shaft 3, ensures a tight connection, preventing relative movement between components. This reduces or even eliminates wear, noise, and loosening caused by slight relative movement, improving connection reliability and component lifespan. Furthermore, it allows for efficient torque transmission between components, ensuring the optimal performance of the intermediate shaft assembly.

[0037] For example, the housing 2 of this disclosure can form an annular structure in the chamber 110, which can form the aforementioned receiving chamber 210. The annular structure can have two oppositely arranged openings, and its inner wall can form a second connecting surface 220. The intermediate shaft 3 can pass through the opening, and the outer ring 42 of the bearing member 4 sleeved outside the intermediate shaft 3 can form a first connecting surface 43.

[0038] The bearing component 4 can be positioned at the center of the housing 2 along the extension direction of the chamber 110, so as to... Figure 1 and Figure 2 Taking the direction shown in the diagram as an example, the bearing component 4 is located in the middle position of the housing 2 in the left-right direction, and ensures that when the intermediate shaft 3 does not undergo relative displacement, the first connecting surface 43 of the bearing component 4 can be completely covered by the second connecting surface 220. This ensures the stability of the intermediate shaft assembly and the bearing component 4 during operation. When the intermediate shaft 3 undergoes relative displacement, the bearing component 4 is positioned such that... Figure 1 and Figure 2Taking the direction shown in the diagram as an example, the intermediate shaft 3 can be tilted from the lower left to the upper right. The upper part of the bearing component 4 can swing to the left so that part of its area moves out of the housing 2. Conversely, the lower part of the bearing component 4 can swing to the right so that part of its area moves out of the housing 2. At this time, the swing angle of the bearing component 4 and the intermediate shaft 3 relative to the housing 2 can be the limit swing angle. Alternatively, the intermediate shaft 3 can be tilted from the upper left to the lower right. The upper part of the bearing component 4 can swing to the right so that part of its area moves out of the housing 2. Conversely, the lower part of the bearing component 4 can swing to the left so that part of its area moves out of the housing 2. At this time, the swing angle of the bearing component 4 and the intermediate shaft 3 relative to the housing 2 can also be the limit swing angle. In order to prevent the bearing component 4 from falling out of the housing 2, the swing amplitude of the bearing component 4 and the intermediate shaft 3 relative to the housing 2 should be kept within the limit swing angle to ensure the stability of the intermediate shaft assembly during operation.

[0039] In embodiments of this disclosure, such as Figures 1 to 4 As shown, the chamber 110 may have a limiting structure 5 for restricting the movement of the housing 2 along the extending direction of the chamber 110. The limiting structure 5 can ensure the stability of the housing 2 after the connection between the housing 2 and the chamber 110, and prevent the friction generated when the intermediate shaft 3 and the bearing 4 swing in the housing 2 from causing the housing 2 to be displaced in the chamber 110, thereby also ensuring the connection stability between the bearing 4 and the housing 2.

[0040] The limiting structure 5 can limit the housing 2 in various ways, such as Figures 1 to 4 As shown, for example, the limiting structure 5 can be provided on one side of the housing 2. After the housing 2 is installed in the chamber 110, the side wall of one side can abut against the limiting structure 5. Thus, when the housing 2 has a tendency to move within the chamber 110, the limiting structure 5 can restrict the movement of the housing 2, so that the limiting structure 5 can improve the limiting effect on the housing 2 to a certain extent.

[0041] In other embodiments, the limiting structure 5 may include a first limiting member 51 and a second limiting member 52 spaced apart along the extending direction of the chamber 110. The first limiting member 51 may abut against one side of the housing 2, and the second limiting member 52 may abut against the opposite side of the housing 2. That is, the first limiting member 51 and the second limiting member 52 may be disposed on both sides of the housing 2 to clamp the housing 2 between them. In this way, the housing 2 can be limited from both sides simultaneously to prevent the housing 2 from moving within the chamber.

[0042] In addition, the first limiting member 51 and the second limiting member 52 can also be located on one side of the housing 2 at the same time. In this case, the first limiting member 51 is provided on part of the inner wall surface of the chamber 110, and the second limiting member 52 can be provided on another part of the inner wall surface. The first limiting member 51 and the second limiting member 52 can simultaneously limit one side of the housing 2.

[0043] It should be noted that the bracket 1 of this disclosure can be configured as a plastic structure. In this way, when the housing 2 is assembled with the bracket 1, the bracket 1 can undergo a certain deformation, which facilitates the housing 2 to be installed in the cavity 110 and located between the first limiting member 51 and the second limiting member 52.

[0044] Among them, such as Figures 1 to 3 As shown, at least one of the first limiting member 51 and the second limiting member 52 may include a protrusion structure 200 extending toward the interior of the chamber 110. The protrusion structure 200 can effectively limit the housing 2 while ensuring a simplified structure within the chamber 110. Exemplarily, the first limiting member 51 may be configured as a boss structure extending toward the interior of the chamber 110, which may abut against the outer wall of the housing 2 along the extension direction of the chamber 110 to increase the connection area between the first limiting member 51 and the housing 2. The second limiting member 52 may be configured as a protrusion structure extending toward the interior of the chamber 110 to abut against the opposite side of the housing 2; or, both the first limiting member 51 and the second limiting member 52 may be configured as protrusion structures extending toward the interior of the chamber 110, as long as they can restrict the movement of the housing 2.

[0045] The protruding structure 200 can be integrally formed with the chamber 110, or the protruding structure 200 can be connected to the inner wall of the chamber 110 through a connector.

[0046] In addition, such as Figures 1 to 3 As shown, at least one of the first limiting member 51 and the second limiting member 52 can be provided in multiples, with multiple first limiting members 51 and / or multiple second limiting members 52 arranged circumferentially around the cavity 110. When the limiting structure 5 is constructed as a protrusion structure, multiple protrusion structures can be arranged circumferentially around the cavity 110, thereby abutting against multiple areas on the same side of the housing 2, thus reducing the space occupied by the limiting structure 5 while ensuring the limiting effect of the limiting structure 5 on the housing 2.

[0047] In some possible implementations, such as Figure 1 , Figure 2 and Figure 4As shown, the housing 2 may include a mating surface 300 for connecting with the front bulkhead of the vehicle, and a seal 6 may be provided on the mating surface 300. The seal 6 can ensure the sealing of the housing 2 after it is connected with the front bulkhead of the vehicle, thereby achieving sound insulation and preventing external impurities such as water and dust from entering the chamber 110 to a certain extent, thus ensuring the normal use of the intermediate shaft 3.

[0048] For example, the seal 6 can be configured as a sealing sponge, which can be attached to the mating surface 300. Since the sealing sponge has a certain degree of compression resilience, it can fill the gaps in the connection area between the mating surface 300 and the front bulkhead as much as possible, thereby forming an effective seal. In addition, the sealing sponge itself also has certain water absorption, dustproof and sound insulation properties, thereby ensuring the normal use of the intermediate shaft 3.

[0049] The second aspect of this disclosure, such as Figure 5 As shown, a steering system is provided, including the aforementioned intermediate shaft assembly. It should be noted that this steering system possesses all the beneficial effects of the aforementioned intermediate shaft assembly, which will not be elaborated upon here.

[0050] A third aspect of this disclosure provides a vehicle including the aforementioned steering system. It should be noted that this vehicle possesses all the beneficial effects of the aforementioned steering system, which will not be elaborated upon further herein.

[0051] In summary, this disclosure exemplarily illustrates the use of the intermediate shaft assembly.

[0052] When there is no relative displacement, the intermediate shaft 3, while rotating, can also drive the inner ring 41 of the bearing 4 to rotate, thereby transmitting the torque of the steering wheel to the vehicle's steering gear, which in turn drives the tires to rotate. After relative displacement occurs, the intermediate shaft 3 and the bearing 4 can swing relative to the housing 2 to a certain extent. This can absorb at least a portion of the force on the intermediate shaft 3 within the bracket 1, and can reduce or avoid the force on the bearing 4, thereby preventing noise from the intermediate shaft assembly and extending the service life of the bearing 4. In addition, this allows for flexible arrangement of the steering wheel angle adjustment rotation axis, thereby improving the design flexibility of the steering column and the overall handling performance of the vehicle.

[0053] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0054] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0055] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
