Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, and specifically relates to a stabilizer bar coupling assembly, a hydraulically clutched stabilizer bar device and a vehicle. Background Art

[0002] As an important component of the suspension system, the stabilizer bar of a vehicle has the main function of connecting the suspension components on both sides, effectively suppressing the roll of the vehicle when turning, thereby improving the vehicle's handling stability and driving safety. However, when driving on rough roads, the independent bouncing of the left and right wheels due to uneven ground will interfere with each other, and this interference often has an adverse effect on the vibration comfort of the vehicle.

[0003] To solve this problem, some existing technologies integrate a clutch device inside the stabilizer bar, aiming to dynamically adjust the working state of the stabilizer bar according to different road conditions to balance the requirements between handling stability and ride comfort. However, these clutch devices often face a key problem in practical applications: the engagement process is not smooth enough, and it is difficult to achieve a stable engagement or disengagement state. This not only affects the vehicle's ability to respond immediately to changes in road conditions, but may also increase the sense of instability during driving and reduce the overall driving experience.

[0004] Therefore, there is room for improvement in the clutch device. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Reference below Figure 1 - Figure 7 A stabilizer bar coupling assembly 20 according to an embodiment of the present invention is described.

[0038] It is worth noting that the stabilizer bar coupling assembly 20 according to an embodiment of the present invention is applied to a stabilizer bar of a vehicle.

[0039] like Figure 1 - Figure 2 As shown, the stabilizer bar coupling assembly 20 according to the first embodiment of the utility model comprises: a first coupling body 21 and a second coupling body 24. The stabilizer bar coupling assembly 20 has a coupled state and a decoupled state.

[0040] Specifically, combined Figure 1 When the first coupling body 21 and the second coupling body 24 are locked by meshing with the gear ring, the stabilizer bar coupling assembly 20 enters the coupled state. On the contrary, when the first coupling body 21 and the second coupling body 24 are free to rotate by disengaging the gear ring so that the rotation of each other does not interfere with each other, the stabilizer bar coupling assembly 20 enters the uncoupled state.

[0041] The first coupling body 21 includes a first rotating body 211 and a first gear ring 212 . The first gear ring 212 surrounds the first rotating body 211 and is movable in the axial direction.

[0042] Combination Figure 1 In the present invention, the direction in which the first rotating body 211 extends along the length is called the axial direction, the direction perpendicular to the axial direction is called the radial direction, and the direction surrounding the axial direction is called the circumferential direction.

[0043] Optionally, the first gear ring 212 is located outside the first rotating body 211 and is disposed around the first rotating body 211. When the first gear ring 212 moves along the axial direction of the first rotating body 211, the effect of locking or unlocking the second coupling body 24 can be achieved.

[0044] Combination Figure 3 The second coupling body 24 includes a second rotating body 241 and a second gear ring 242. The second rotating body 241 is coaxially rotatably connected with the first rotating body 211, and the second gear ring 242 is disposed around the second rotating body 241.

[0045] Optionally, the second gear ring 242 is located outside the second rotating body 241 and is disposed around the second rotating body 241 .

[0046] In some embodiments, a limiting structure is provided between the first rotating body 211 and the second rotating body 241. The limiting structure can ensure that the two rotate synchronously, thereby improving the transmission efficiency of the two.

[0047] In addition, the first rotating body 211 and the second rotating body 241 are rotatably connected to achieve pre-positioning of the first coupling body 21 and the second coupling body 24 , thereby improving the accuracy of the meshing of the first gear ring 212 and the second gear ring 242 .

[0048] Optionally, the limiting structure between the first rotating body 211 and the second rotating body 241 includes, but is not limited to: a pin slot structure, a gear meshing structure, a spline connection structure, etc.

[0049] In some optional embodiments, one of the first rotating body 211 and the second rotating body 241 is a positioning column, and the other is a positioning groove matched with the positioning column. During the coupling process of the first coupling body 21 and the second coupling body 24, the rotating body designed as the positioning column is naturally guided and directed to the positioning groove preset on the other rotating body. The positioning groove completely matches the size, shape and position of the positioning column.

[0050] When the positioning column enters the positioning groove, the relative position between the two rotating bodies is accurately fixed. At this time, the first rotating body 211 and the second rotating body 241 not only achieve accurate axial positioning, but also limit the radial and circumferential movement between them to a certain extent, thereby ensuring the stability and reliability of the entire stabilizer bar coupling assembly 20.

[0051] The stabilizer bar coupling assembly 20 has a coupled state and a decoupled state. In the coupled state, the first gear ring 212 is meshed with the second gear ring 242 . In the decoupled state, the first gear ring 212 is axially away from the second gear ring 242 to be disengaged from the second gear ring 242 .

[0052] Specifically, when the stabilizer bar coupling assembly 20 is in a coupled state, the first gear ring 212 meshes with the second gear ring 242. This meshing relationship ensures that power or torque can be efficiently and smoothly transmitted from one rotating body to another. During the meshing process, the teeth of the first gear ring 212 are in close contact with the teeth of the second gear ring 242 to form a stable transmission chain. At this time, the first rotating body 211 and the second rotating body 241 maintain synchronous rotation, and the transmission efficiency of the speed and torque reaches a high level.

[0053] When the stabilizer bar coupling assembly 20 needs to enter the decoupling state, the first gear ring 212 will move away from the second gear ring 242 in the axial direction, thereby disengaging from the second gear ring 242. This decoupling operation can be achieved by reversely driving the first gear ring 212 in the first coupling body 21, so that the two gear rings can be separated freely. In the decoupling state, the power transmission between the first rotating body 211 and the second rotating body 241 is cut off, and they can rotate or stop independently. This design allows the stabilizer bar coupling assembly 20 to flexibly adapt to different working requirements. For example, when it is necessary to stop the transmission, the two gear rings can be separated.

[0054] It should be noted that the structure used to apply axial driving force to the first gear ring 212 in the stabilizer bar coupling assembly 20 in the present application can adopt existing structures in the prior art, such as a hydraulic structure, etc. The hydraulic structure is not limited or elaborated here.

[0055] According to some embodiments of the present invention, the stabilizer bar coupling assembly 20 further includes a guide structure 25 , and the guide structure 25 includes a guide rib 251 and a guide groove 252 extending along the axial direction.

[0056] The guide structure 25 is provided to ensure that the first gear ring 212 can move smoothly and accurately during the coupling and decoupling processes.

[0057] In some embodiments not shown in the figures, the guide ribs 251 are provided on the inner circumference of the first gear ring 212. The guide ribs 251 are arranged in such a way that they can directly act on the rotating body in contact with the first gear ring 212. This direct action mechanism enables the first gear ring 212 to smoothly move along a preset path when moving, reducing the possibility of deviation and shaking.

[0058] The guide groove 252 is provided on the outer circumference of at least one of the first rotating body 211 and the second rotating body 241. Then, the first gear ring 212 can achieve a stable and reliable guiding effect with at least one of the first rotating body 211 and the second rotating body 241 through the guide groove 252.

[0059] Specifically, when a coupling operation is required, the first gear ring 212 moves axially along the guide groove 252 on the first rotating body 211. During this process, the guide rib 251 is tightly embedded in the guide groove 252, providing stable guidance and support for the first gear ring 212. As the first gear ring 212 continues to move, it gradually approaches and eventually meshes with the second gear ring 242 on the second rotating body 241. This meshing process becomes accurate and reliable due to the presence of the guide structure 25, ensuring the continuity and stability of power transmission.

[0060] Alternatively, the guide rib 251 is disposed on the outer circumference of at least one of the first rotating body 211 and the second rotating body 241 , and the guide groove 252 is disposed on the inner circumference of the first gear ring 212 .

[0061] In the design of the stabilizer bar coupling assembly 20, there is another configuration scheme of the guide structure 25, that is, the guide rib 251 is arranged on the outer circumference of at least one of the first rotating body 211 or the second rotating body 241, and the corresponding guide groove 252 is arranged on the inner circumference of the first gear ring 212. This reverse configuration can also achieve a stable and reliable guiding function.

[0062] Specifically, when the first gear ring 212 needs to slide axially to couple or decouple with the second gear ring 242 on the rotating body, the guide groove 252 on its inner circumference will closely cooperate with the guide rib 251 on the outer circumference of the rotating body. The guide rib 251 slides along the track of the guide groove 252, providing a clear movement path and stable support for the first gear ring 212. This matching mechanism ensures the accuracy and stability of the first gear ring 212 during movement, reducing the negative impact caused by position offset or shaking.

[0063] Combination Figure 2 , Figure 4 The guide rib 251 is arranged on the outer peripheral surface of the first rotating body 211.

[0064] In some embodiments, Figure 4 As shown, a plurality of guide ribs 251 are arranged at intervals along the circumferential direction on the outer circumferential surface of the first rotating body 211, so that the portion of the first rotating body 211 provided with the guide ribs 251 constitutes a spline shaft 2511, and a plurality of guide grooves 252 are provided on the inner circumferential surface of the first gear ring 212, and the plurality of guide grooves 252 are arranged one-to-one correspondingly to the plurality of guide ribs 251.

[0065] By providing circumferentially spaced guide ribs 251, not only the structural strength of the rotating body is enhanced, but also this part of the rotating body is functionally similar to the spline shaft 2511, providing a precise guide path for the components that cooperate with it.

[0066] like Figure 5 As shown, correspondingly, guide grooves 252 corresponding to the guide ribs 251 are provided on the inner circumference of the first gear ring 212. The shape, size and position of the guide grooves 252 are adapted to the guide ribs 251 to ensure that they can perfectly match the guide ribs 251 on the first rotating body 211. When the first gear ring 212 needs to slide axially, the guide grooves 252 on its inner circumference will slide along the guide ribs 251 on the outer circumference of the rotating body, thereby achieving a stable and reliable guiding function.

[0067] This arrangement not only improves the transmission efficiency and precision of the stabilizer bar coupling assembly 20, but also enhances its durability and reliability. By ensuring the close fit between the guide rib 251 and the guide groove 252, the friction and wear during the sliding process can be effectively reduced, and the service life of the assembly can be extended.

[0068] According to the stabilizer bar coupling assembly 20 of some embodiments of the present invention, the dimension of the guide groove 252 along the circumferential direction is the width dimension, and the width of the guide groove 252 is greater than the width of the guide rib 251 .

[0069] First, the wider width of the guide groove 252 provides a larger sliding space for the guide rib 251, reducing the jamming phenomenon caused by slight dimensional deviations or manufacturing tolerances, thereby ensuring smooth axial sliding between the first gear ring 212 and the first rotating body 211 (or the second rotating body 241).

[0070] Secondly, even when affected by adverse factors such as external vibration, impact or load changes, the wider guide groove 252 can effectively maintain the stable position of the guide rib 251 therein, preventing it from deviating from the predetermined sliding trajectory, thereby ensuring the reliable operation of the stabilizer bar coupling assembly 20.

[0071] In addition, in some optional embodiments, lubricant is also filled between the guide groove 252 and the guide rib 251. Then the wider guide groove 252 is conducive to the accommodation and distribution of the lubricant. During the sliding process, the lubricant is filled in the gap between the guide groove 252 and the guide rib 251, reducing the friction coefficient, reducing the wear rate, and further improving the sliding efficiency and component life.

[0072] According to some embodiments of the present invention, the stabilizer bar coupling assembly 20 is as follows: Figure 2 - Figure 5 As shown, the end surface of the first gear ring 212 facing the second gear ring 242 forms the first meshing teeth 2121, the inner circumference of the first gear ring 212 forms the guide groove 252, and the inner circumference of the first gear ring 212 between two adjacent guide grooves 252 is the spacer 253. The first meshing teeth 2121 and the spacer 253 are arranged one by one.

[0073] In the above technical solution, these spacers 253 not only play the role of separating the guide grooves 252, but also enhance the overall structural strength of the first gear ring 212. They are arranged one by one with the first meshing teeth 2121, which means that each meshing tooth corresponds to a spacer 253. This layout helps to optimize the stress condition of the first gear ring 212, reduce stress concentration, and improve the bearing capacity and service life of the component.

[0074] In addition, the spacer 253 is provided to facilitate the assembly and positioning of the stabilizer bar coupling assembly 20. During the assembly process, the spacer 253 can be used to ensure that the relative position between the first gear ring 212 and the first rotating body 211 (or the second rotating body 241) is correct to avoid misalignment or deflection. At the same time, the spacer 253 can also be used as a reference point for adjusting the gap or compensating for wear, so that the stabilizer bar coupling assembly 20 can maintain stable performance during long-term use.

[0075] In some embodiments, surfaces of all first meshing teeth 2121 and all spacers 253 that face the axis of the first gear ring 212 are located on the same cylindrical surface.

[0076] Combination Figure 4 - Figure 5 , from the axial direction of the first gear ring 212, the edges or contact surfaces of the first meshing teeth 2121 for transmitting power and the spacers 253 for separating, supporting or adjusting the gap between them are perfectly fitted on the surface of an imaginary cylinder. This alignment ensures high precision, low noise and long-term stability of the stabilizer bar coupling assembly 20 during operation.

[0077] This setup also simplifies the manufacturing and assembly process because all related parts follow the same cylindrical surface standards, reducing assembly difficulties caused by dimensional deviations or position errors.

[0078] According to some embodiments of the stabilizer bar coupling assembly 20 of the present invention, the meshing teeth of the first gear ring 212 and the second gear ring 242 are trapezoidal teeth or triangular teeth.

[0079] In some embodiments, Figure 1 - Figure 2 As shown, the meshing teeth of the first gear ring 212 and the second gear ring 242 are trapezoidal teeth. This is because the wider tooth surface and gradual tooth shape of the trapezoidal teeth can withstand larger normal loads and tangential loads, and are suitable for transmitting high power and high torque. The involute tooth shape design of the trapezoidal teeth makes the meshing between teeth more stable, reduces impact and vibration, and improves transmission efficiency and service life. The processing of trapezoidal teeth is relatively simple, and can be achieved through various methods such as hobbing and gear shaping, thereby reducing manufacturing costs.

[0080] In some optional embodiments, the meshing teeth of the first gear ring 212 and the second gear ring 242 are triangular teeth. This is because the tooth surfaces of the triangular teeth overlap to a large extent, which can not only improve the transmission efficiency, but also ensure good stability during the transmission process, and are not prone to impact and vibration. Therefore, the triangular teeth have low noise and long service life.

[0081] like Figure 2 - Figure 3 As shown, the stabilizer bar coupling assembly 20 according to some embodiments of the present invention further includes an elastic member 26 connected between the first rotating body 211 and the first gear ring 212 to drive the first gear ring 212 to disengage from the second gear ring 242 .

[0082] Specifically, when the first gear ring 212 needs to be disengaged from the second gear ring 242, the elastic member 26 can store and release energy to drive the first gear ring 212 to slide axially, thereby disengaging from the second gear ring 242. This design makes the clutch operation simple and quick. During the clutch process, the elastic member 26 can also play a role in buffering and shock absorption, reducing the impact and vibration caused by sudden disengagement, and protecting other components of the stabilizer bar coupling assembly 20 from damage.

[0083] Of course, in other embodiments, the elastic member 26 is connected between the first rotating body 211 and the first gear ring 212 , and can also be used to drive the first gear ring 212 and the second gear ring 242 to approach and mesh with each other.

[0084] In some optional embodiments, the elastic member 26 includes but is not limited to a spring member, a rubber member, etc.

[0085] In some embodiments, the first rotating body 211 includes a base, which is disposed at an end of the first rotating body 211 and extends outward in a direction away from the axis thereof.

[0086] One end of the elastic member 26 is connected to the end of the first gear ring 212 away from the first meshing tooth 2121, and the other end of the elastic member 26 is connected to the base of the first rotating body 211. This arrangement realizes flexible connection and force transmission during dynamic operation.

[0087] Optionally, there are multiple elastic members 26 and they are distributed at intervals along the circumference of the first rotating body 211 .

[0088] The multiple elastic members 26 can provide elastic forces from multiple directions at the same time, so as to ensure that the first gear ring 212 is subjected to uniform and balanced forces when it is separated from the second gear ring 242. This uniform force not only helps to reduce stress concentration and wear caused by uneven force, but also improves the stability and reliability of the clutch action. Each elastic member 26 can work independently, reducing the load and failure risk of a single component.

[0089] like Figure 7 As shown, a hydraulically clutched stabilizer bar device 100 according to an embodiment of the second aspect of the utility model comprises: a stabilizer bar assembly 10 and a stabilizer bar coupling assembly 20 , wherein the stabilizer bar assembly 10 comprises a first rod body 101 and a second rod body 102 .

[0090] The first rotating body 211 of the first coupling body 21 is connected to the first rod 101, and the second rotating body 241 of the second coupling body 24 is connected to the second rod 102. The above-mentioned stabilizer bar coupling assembly 20 is the stabilizer bar coupling assembly 20 of the first aspect of the utility model.

[0091] The engagement and disengagement of the stabilizer bar assembly 10 is driven by the stabilizer bar coupling assembly 20 .

[0092] like Figure 7 As shown, the stabilizer bar assembly 10 includes: a first rod body 101 and a second rod body 102. The first rod body 101 and the second rod body 102 are two independent rod bodies, and one end of the first rod body 101 and the second rod body 102 away from each other is connected to the suspension of the vehicle.

[0093] When the vehicle is in a stable driving state, the first rod body 101 and the second rod body 102 are separated from each other, and when there is no significant roll moment acting on the vehicle body, the first rod body 101 and the second rod body 102 will remain relatively still or have a slight relative movement in the radial direction. At this time, they will not be involved with each other, and will not have a significant impact on the driving state of the vehicle. Therefore, the driver and passengers can enjoy a stable and comfortable riding experience.

[0094] Among them, the stabilizer bar coupling assembly 20 is the stabilizer bar coupling assembly 20 of the first embodiment of the utility model, the first rotating body 211 of the first coupling body 21 is connected to the first rod body 101, and the second rotating body 241 of the second coupling body 24 is connected to the second rod body 102.

[0095] When the driving state of the vehicle changes, such as when turning or driving on an uneven road, the vehicle body will generate a roll moment. At this time, the stabilizer bar coupling assembly 20 enters the coupled state from the decoupled state, and the first gear ring 212 of the first coupling body 21 approaches the second gear ring 242 of the second coupling body 24 and meshes with it, thereby achieving the connection between the first rod body 101 and the second rod body 102, thereby increasing the restraining force of the first rod body 101 and the second rod body 102 on each other, thereby achieving the effect of preventing the vehicle from rolling.

[0096] When the roll moment decreases or disappears, the stabilizer bar coupling assembly 20 enters the decoupling state from the coupling state. At this time, the first gear ring 212 of the first coupling body 21 gradually moves away from the second gear ring 242, so that the first gear ring 212 is separated from the second gear ring 242, and the first rod body 101 and the second rod body 102 are separated, and the mutual restraint between the two is stopped, so as to restore the stable driving state of the vehicle.
