Description

Technical Field

[0001] This utility model relates to the field of vehicle component technology, and in particular to an active lateral stabilizer bar and a vehicle having the same. Background Technology

[0002] As competition intensifies in the new energy passenger vehicle market and vehicle configurations are further upgraded, active stabilizer bars, previously used only in high-end models, are now being used more and more extensively. For example... Figure 1 and Figure 2 As shown, in the prior art, the fixed-end rocker arm 91 and the actuator housing 92 are welded together to form the input end, while the output-end rocker arm 93 is threadedly connected to the end-face spline connector 94. The end-face spline connector 94 is connected to the output shaft of the three-stage planetary gear reduction mechanism 95 through a shock-absorbing structure. During operation, the output-end rocker arm 93 rotates with the output torque of the actuator. Therefore, a thrust bearing 97 is located between the output-end rocker arm 93 and the housing 92. The outer ring of the thrust bearing 97 is clearance-fitted with the housing 92, and the inner ring is connected to the end-face spline connector 94. The end-face spline connector 94 is connected to the output shaft of the three-stage planetary gear reduction mechanism 95, thereby forming torque output.

[0003] To secure the inner ring of the thrust bearing 97, in the prior art, a groove 941 is formed on the end face spline connector 94, a retaining spring 942 is disposed within the groove 941, and a shim 943 is disposed between the retaining spring 942 and the thrust bearing 97. By using shims 943 of different specifications, the thrust force on the end face of the thrust bearing 97 can be adjusted.

[0004] However, the adjustment method using shims 943 is complex, cumbersome, and difficult to control, which in turn affects the axial force on the thrust bearing 97. Furthermore, because shims 943 are prone to deformation, this can lead to abnormal bearing noise and premature failure. Utility Model Content

[0005] To address the aforementioned problems, this invention provides an active lateral stabilizer bar and a vehicle incorporating it. This active lateral stabilizer bar enables more convenient and quick adjustment of the thrust bearing axial force and eliminates the risk of abnormal noise from the snap ring structure.

[0006] This utility model provides an active lateral stabilizer bar, including a housing, an end-face spline connector, and a thrust bearing. The end-face spline connector and the thrust bearing are disposed within the housing. The thrust bearing includes an inner bearing ring and an outer bearing ring. The outer bearing ring is connected to the inner sidewall of the housing, and the inner bearing ring is connected to the outer sidewall of the end-face spline connector. An outer ring compression nut and an inner ring compression nut are disposed on one end of the thrust bearing facing the active lateral stabilizer bar. The outer ring compression nut is disposed on the inner sidewall of the housing and compresses the outer bearing ring, and the inner ring compression nut is disposed on the outer sidewall of the end-face spline connector and compresses the inner bearing ring.

[0007] Furthermore, the outer ring clamping nut and the inner ring clamping nut are arranged in a staggered manner.

[0008] Furthermore, along the direction toward the thrust bearing to the direction away from the thrust bearing, both the outer ring clamping nut and the inner ring clamping nut are provided with a first nut segment and a second nut segment. On the outer ring clamping nut, an outer ring stepped surface is formed between the first nut segment and the second nut segment, facing the inner ring clamping nut. On the inner ring clamping nut, an inner ring stepped surface is formed between the first nut segment and the second nut segment, facing the outer ring clamping nut. The inner ring stepped surface and the outer ring stepped surface are arranged opposite to each other.

[0009] Furthermore, both the outer ring step surface and the inner ring step surface are inclined.

[0010] Furthermore, on the outer ring clamping nut, the inner diameter of the first nut segment is larger than the inner diameter of the second nut segment, and on the inner ring clamping nut, the outer diameter of the first nut segment is larger than the outer diameter of the second nut segment.

[0011] Furthermore, the distance from the inner wall of the second nut segment of the outer ring clamping nut to the axis of the housing is less than the distance from the outer wall of the first nut segment of the inner ring clamping nut to the axis of the housing.

[0012] Furthermore, a plurality of recesses are formed on the end face of the outer ring clamping nut away from the thrust bearing, and / or a plurality of notches are provided on the end of the inner ring clamping nut away from the thrust bearing.

[0013] Furthermore, the active lateral stabilizer bar includes an output rocker arm and a rocker arm clamping nut. The rocker arm clamping nut is connected to the end face spline connector and fixes the output rocker arm to the end face spline connector.

[0014] Furthermore, a sealing ring is provided between the rocker arm clamping nut and the inner wall of the housing.

[0015] A vehicle including the aforementioned active lateral stabilizer bar.

[0016] In summary, in this invention, the outer and inner rings of the bearing are clamped by an outer ring clamping nut and an inner ring clamping nut, respectively. In this structure, the outer and inner ring clamping nuts apply clamping force to the outer and inner rings along the axial direction of the active lateral stabilizer bar. Since the clamping nuts are threaded, the axial force of the thrust bearing can be adjusted by the depth of thread tightening. Because shims are no longer required, the connection between each nut and the outer or inner ring of the bearing is relatively tight, eliminating the risk of abnormal noise from the snap ring structure. Furthermore, by staggering the outer and inner ring clamping nuts, the axial and radial dimensions of the housing are reduced while maintaining the rigidity of the outer and inner ring clamping nuts themselves, resulting in a more compact structure.

[0034] This invention provides an active lateral stabilizer bar and a vehicle having the same. The active lateral stabilizer bar makes it easier and faster to adjust the axial force of the thrust bearing 30, and can eliminate the risk of abnormal noise from the snap ring structure.

[0035] like Figure 3 and Figure 4 As shown, the active lateral stabilizer bar provided in this embodiment of the present invention includes a housing 10, an end-face spline connector 20, and a thrust bearing 30. Both the end-face spline connector 20 and the thrust bearing 30 are disposed within the housing 10. The thrust bearing 30 includes an inner bearing ring 31 and an outer bearing ring 32. The outer bearing ring 32 is connected to the inner wall of the housing 10, and the inner bearing ring 31 is connected to the outer wall of the end-face spline connector 20. At the output end of the thrust bearing 30 facing the active lateral stabilizer bar (i.e.,...) Figure 3 and Figure 4 An outer ring clamping nut 41 and an inner ring clamping nut 42 are provided on one end of the bearing (the right end of the bearing). The outer ring clamping nut 41 is provided on the inner side wall of the housing 10 and clamps the outer ring 32 of the bearing. The inner ring clamping nut 42 is provided on the outer side wall of the end face spline connector 20 and clamps the inner ring 31 of the bearing. Understandably, in order to install the outer ring clamping nut 41 and the inner ring clamping nut 42, threads are provided on the inner surface of the housing 10 and the outer surface of the end face spline connector 20.

[0036] In this embodiment, the outer ring clamping nut 41 and the inner ring clamping nut 42 respectively clamp the outer ring 32 and the inner ring 31 of the bearing. In this structure, the outer ring clamping nut 41 and the inner ring clamping nut 42 apply a clamping force to the outer ring 32 and the inner ring 31 of the bearing along the axial direction of the active lateral stabilizer bar. Since the clamping nuts are threaded, the axial force of the thrust bearing 30 can be adjusted by the depth of thread tightening. Because shims are no longer provided, the connection between each nut and the outer ring 32 or the inner ring 31 of the bearing is relatively tight, which can eliminate the risk of abnormal noise from the snap ring structure.

[0037] Please continue to refer to Figure 3 and Figure 4 The outer ring clamping nut 41 and the inner ring clamping nut 42 are staggered, which makes the axial and radial dimensions of the housing 10 smaller and the structure more compact while ensuring the rigidity of the outer ring clamping nut 41 and the inner ring clamping nut 42 themselves.

[0038] Specifically, along the direction toward the thrust bearing 30 to the direction away from the thrust bearing 30 (i.e.) Figure 3(From left to right in the middle), both the outer ring clamping nut 41 and the inner ring clamping nut 42 are provided with a first nut section 51 and a second nut section 52. For example... Figure 4 As shown, on the outer ring clamping nut 41, an outer ring stepped surface 411 is formed between the first nut segment 51 and the second nut segment 52, facing towards the inner ring clamping nut 42. On the inner ring clamping nut 42, an inner ring stepped surface 421 is formed between the first nut segment 51 and the second nut segment 52, facing towards the outer ring clamping nut 41. The outer ring stepped surface 411 and the inner ring stepped surface 421 are arranged opposite to each other. More specifically, both the outer ring stepped surface 411 and the inner ring stepped surface 421 are inclined.

[0039] In this embodiment, on the outer ring clamping nut 41, the inner diameter of the first nut segment 51 is larger than the inner diameter of the second nut segment 52, while on the inner ring clamping nut 42, the outer diameter of the first nut segment 51 is larger than the outer diameter of the second nut segment 52.

[0040] Furthermore, the distance from the inner wall of the second nut segment 52 of the outer ring clamping nut 41 to the axis of the housing 10 is less than the distance from the outer wall of the first nut segment 51 of the inner ring clamping nut 42 to the axis of the housing 10. This further reduces the radial dimension of the housing 10. That is, viewed from the output end of the active lateral stabilizer bar along the axial direction of the housing 10, the second nut segment 52 of the outer ring clamping nut 41 will at least partially obscure the first nut segment 51 on the inner ring clamping nut 42.

[0041] Furthermore, such as Figures 5 to 7 As shown, in this embodiment, a plurality of recesses 412 are formed on the end face of the outer ring clamping nut 41 away from the thrust bearing 30. The recesses 412 can reduce the weight of the outer ring clamping nut 41 on the one hand, and provide a force application point for the installation tool on the other hand, so as to facilitate the installation of the outer ring clamping nut 41.

[0042] Understandably, threads are formed on the outer surface of the outer ring clamping nut 41 so that the outer ring clamping nut 41 can be fixed to the inner surface of the housing 10 by means of thread engagement.

[0043] like Figures 8 to 10 As shown, in this embodiment, a plurality of notches 422 are provided at the end of the inner ring clamping nut 42 away from the thrust bearing 30. Specifically, the notches 422 can be formed on the second nut section 52 of the inner ring clamping nut 42. The notches 422 facilitate the installation of the inner ring clamping nut 42 and reduce its weight.

[0044] Understandably, threads are formed on the inner surface of the inner ring clamping nut 42 so that the inner ring clamping nut 42 can be fixed to the outer surface of the end face spline connector 20 by means of thread engagement.

[0045] Please continue to refer to Figure 3 and Figure 4 In this embodiment, the active lateral stabilizer bar also includes an output rocker arm 61 and a rocker arm clamping nut 62. The rocker arm clamping nut 62 is threadedly connected to the end face spline connector 20, and the output rocker arm 61 is fixedly connected to the end face spline connector 20.

[0046] In this embodiment, threads are provided on the outer surface of the end face spline connector 20, from the position of the thrust bearing 30 toward the output end of the active lateral stabilizer bar to the end of the end face spline connector 20. The inner ring clamping nut 42 and the rocker arm clamping nut 62 are both provided on the threads of the end face spline connector 20.

[0047] Furthermore, a sealing ring 63 is provided between the rocker arm clamping nut 62 and the inner wall of the housing 10 to ensure internal sealing.

[0048] In summary, in this invention, the outer ring clamping nut 41 and the inner ring clamping nut 42 respectively clamp the outer ring 32 and the inner ring 31 of the bearing. In this structure, the outer ring clamping nut 41 and the inner ring clamping nut 42 apply clamping force to the outer ring 32 and the inner ring 31 of the bearing along the axial direction of the active lateral stabilizer bar. Since the clamping nuts are connected by threads, the axial force of the thrust bearing 30 can be adjusted by the depth of thread tightening. Since shims are no longer provided, the connection force between each nut and the outer ring 32 or the inner ring 31 of the bearing is relatively tight, which can eliminate the risk of abnormal noise from the snap ring structure. Furthermore, by staggering the outer ring clamping nut 41 and the inner ring clamping nut 42, the axial and radial dimensions of the housing 10 are smaller and the structure is more compact while ensuring the rigidity of the outer ring clamping nut 41 and the inner ring clamping nut 42.

[0049] This utility model also provides a vehicle including the aforementioned active lateral stabilizer bar. For other technical features of this vehicle, please refer to the prior art, which will not be repeated here.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
