Description
Technical Field
[0001] The present invention belongs to the technical field of vehicle suspensions, and particularly relates to a distributed temporarily decouplable dual-motor harmonic reduction active stabilizer bar. Background Art
[0002] During vehicle driving, the suspension system plays a crucial role in the handling stability and riding comfort of the vehicle. When dealing with complex road conditions, traditional stabilizer bars are difficult to achieve pitch attitude adjustment of the suspension. For example, it is impossible to adjust the pitch attitude during sudden braking of the vehicle, which limits the further improvement of vehicle performance. Moreover, due to structural limitations, traditional single-motor active stabilizer bars have poor stability and passability when facing muddy beach and gravel road conditions.
[0003] With the continuous development of automotive technology, the demand for active stabilizer bars is increasing day by day. Existing stabilizer bar structures have deficiencies in terms of passability, handling stability, and comfort, and cannot meet the requirements of modern vehicles for high-performance suspension systems.
[0004] In response to this, we designed a distributed temporarily decouplable dual-motor harmonic reduction active stabilizer bar to solve the above problems. Summary of the Invention

[0009] The stable half-rod actuator module includes an output half-rod, a self-lubricating axial limiting bushing, an electromagnetic clutch output end, a radial limiting bearing, a shaft snap ring, an electromagnetic clutch input end, and a friction plate. The electromagnetic clutch output end is fixed to one side of the end face of the output half-rod by screws. The electromagnetic clutch input end is arranged on one side of the electromagnetic clutch output end. The friction plate is arranged in the inner ring of the electromagnetic clutch output end. The inner ring of the radial limiting bearing is in interference fit with the shaft end of the output half-rod. The outer ring of the radial limiting bearing is fixed to the machine frame. The self-lubricating axial limiting bushing is in transitional fit with the end of the output half-rod shaft.

The shaft snap ring is arranged on one side of the inner ring of the radial limiting bearing.
[0010] The synchronous belt drive mechanism includes a large synchronous belt wheel on the reducer side, a small synchronous belt wheel on the motor side, and a synchronous drive belt. The stepped shaft tube is welded to the large synchronous belt wheel on the reducer side. The synchronous drive belt is arranged between the large synchronous belt wheel on the reducer side and the small synchronous belt wheel on the motor side.
[0011] One side of the small synchronous belt wheel on the motor side is provided with a mounting bracket.

Compared with the traditional integral active stabilizer bar, the split-type dual-motor structure can not only perform pitch adjustment to reduce the risk of forward and backward flipping during high-speed emergency braking and car accidents, but also leaves room for optimizing the control strategy and planning the torque distribution coefficient of the stabilizer bar unit, improving the vehicle's maneuverability.

[0031] Please refer to Figures 1-4 As shown, the present invention is a distributed double-motor harmonic reduction active stabilizer bar that can be temporarily decoupled, including a stable half-rod actuator module 1. Harmonic reduction mechanisms 5 are provided on both sides of the two stable half-rod actuator modules 1 that are close to each other. A synchronous belt drive mechanism 4 is provided outside the harmonic reduction mechanism 5. One side of the synchronous belt drive mechanism 4 is connected to a driving motor 3. A torque transmission component is provided between the two synchronous belt drive mechanisms 4. The harmonic reduction mechanism 5 includes:
[0032] Internal spline flexspline 5.1 and oil seal module. A steel wheel 5.7 is sleeved on the outer side of the internal spline flexspline 5.1 away from the stable half-rod actuator module 1. A stepped shaft tube 5.3 is arranged on the inner side of the internal spline flexspline 5.1 close to the steel wheel 5.7. A bearing bushing and torque rod limiter 5.2 is arranged on the outer side of one end of the stepped shaft tube 5.3 located in the inner cavity of the internal spline flexspline 5.1. A torque tube isolation bearing 5.6 is arranged between the inner ring of the bearing bushing and torque rod limiter 5.2 and the outer wall of the stepped shaft tube 5.3. An elliptical bearing 5.5 is sleeved on the outside of the stepped shaft tube 5.3, and the elliptical bearing 5.5 is arranged inside the internal spline flexspline 5.1. Through the outer ring of the elliptical bearing 5.5, the deformation is facilitated to be transmitted to the internal spline flexspline 5.1, so that the internal spline flexspline 5.1 crawls on the steel wheel 5.7, thereby achieving the purpose of decelerating and increasing torque. An elliptical compensation bushing 5.10 is welded on the stepped shaft tube 5.3. The elliptical compensation bushing 5.10 is arranged between the stepped shaft tube 5.3 and the elliptical bearing 5.5, and the elliptical compensation bushing 5.10 is in interference fit with the inner ring of the elliptical bearing 5.5.

Through the oil seal skeleton 5.8, the oil seal rubber 5.9 is effectively supported, ensuring the roundness retention of the oil seal rubber 5.9 to avoid losing roundness and leaking lubricating fluid in a high-speed working environment.
[0034] The stable half-rod actuator module 1 includes an output half-rod 1.1, a self-lubricating axial limit bushing 1.2, an electromagnetic clutch output end 1.3, a radial limit bearing 1.4, a shaft snap ring 1.5, an electromagnetic clutch input end 1.6, and a friction plate 1.7.

The electromagnetic clutch input end 1.6, the electromagnetic clutch output end 1.3, and the friction plate 1.7 together constitute an electromagnetic clutch module. When the stabilizer bar needs to act, the electromagnetic clutch output end 1.3 clamps the friction plate 1.7, so that the movement of the electromagnetic clutch input end 1.6 is transmitted to the output half-rod 1.1. The inner ring of the radial limit bearing 1.4 is interference-fitted on the shaft end of the output half-rod 1.1, and the outer ring of the radial limit bearing 1.4 is fixed to the frame, effectively playing an accurate radial positioning role. One side of the self-lubricating axial limit bushing 1.2 is transition-fitted to the end of the shaft of the output half-rod 1.1, and the other side of the self-lubricating axial limit bushing 1.2 is closely attached to the stepped shaft tube 5.3. Through the good self-lubricating performance of the self-lubricating axial limit bushing 1.2 itself, the rotational speed difference between the two sides is effectively isolated, and at the same time, the vibration response performance of the system is balanced. The shaft snap ring 1.5 is arranged on one side of the inner ring of the radial limit bearing 1.4 to perform reliable axial positioning on the radial limit bearing 1.4.
[0035] The synchronous belt transmission mechanism 4 includes a large synchronous belt pulley 4.1 on the reducer side, a small synchronous belt pulley 4.2 on the motor side, and a synchronous transmission belt 4.3. The stepped shaft tube 5.3 is welded to the large synchronous belt pulley 4.1 on the reducer side. The synchronous transmission belt 4.3 is arranged for transmission between the large synchronous belt pulley 4.1 on the reducer side and the small synchronous belt pulley 4.2 on the motor side. An installation bracket 9 is arranged on one side of the small synchronous belt pulley 4.2 on the motor side. The driving motor 3 is installed on the installation bracket 9, and the output end of the driving motor 3 passes through the installation bracket 9 and is connected to the small synchronous belt pulley 4.2 on the motor side.
[0036] The torque transmission assembly includes a connector 6, a spline torque rod 7, and a spline torque tube 8. The outer walls of the two spline torque tubes 8 on the sides away from each other are connected to the connector 6. The spline torque rod 7 is arranged inside the spline torque tube 8, and the spline torque rod 7 cooperates with the inner wall of the spline torque tube 8. One end of the two spline torque rods 7 away from each other passes through the inner spline flexspline 5.1 and the inner cavity of the stepped shaft tube 5.3, and is in spline cooperation with the output half-rod 1.1. The connector 6 is connected to the steel wheel 5.7. The electromagnetic clutch input end 1.6 is in keyway cooperation with the spline torque rod 7, and the friction plate 1.7 is in clearance fit on the spline torque rod 7.
[0037] An actuator threaded end cap 2 is installed at the tail end of the stable half-rod actuator module 1, further playing a sealing role to ensure that the system has good sealing performance and prevent water seepage and oil leakage.
[0038] Example:
[0039] During the actual installation and debugging process, first install the mounting bracket 9 to the appropriate position of the vehicle frame, and install the drive motor 3 to the mounting bracket 9, ensure the stability of the installation of the drive motor 3 and the mounting bracket 9, ensure that the power output shaft of the drive motor 3 and the synchronous belt transmission mechanism 4 are connected accurately, and adjust the tension of the synchronous transmission belt 4.3 to a suitable state to avoid slipping due to excessive looseness and increase component wear due to excessive tightness;
[0040] The assembly accuracy of the components of the harmonic reduction mechanism 5 is extremely important, especially the coordination between the elliptical compensation sleeve 5.10 and the elliptical bearing 5.5, the internal spline flexible wheel 5.1 and the steel wheel 5.7, and the installation of the oil seal module. The operation should be carried out strictly in accordance with the design requirements to ensure the deceleration and torque increase effect and the system sealing.
[0041] The spline torque tube 8 and the spline torque rod 7 must be tightly connected to ensure stable torque transmission. After the stable half-rod actuator module 1 is installed, the actuator threaded end cap 2 is finally installed to complete the installation of the entire stable rod;
[0042] During the debugging process, the drive motor 3 is started, and the small synchronous pulley 4.2 on the motor side is driven to rotate through the drive motor 3. Under the action of the synchronous transmission belt 4.3, the large synchronous pulley 4.1 on the reducer side is driven to rotate, and the stepped shaft tube 5.3 is welded and connected to the large synchronous pulley 4.1 on the reducer side, and then the speed and torque are transmitted to the harmonic reduction mechanism 5, and the elliptical bearing 5.5 is driven to rotate through the stepped shaft tube 5.3, and the deformation is transmitted to the inner spline flexible wheel 5.1 through the outer ring of the elliptical bearing 5.5, so that the inner spline flexible wheel 5.1 climbs on the steel wheel 5.7, thereby achieving the purpose of deceleration and torque increase;
[0043] The torque increased by the harmonic reduction mechanism 5 is transmitted to the spline torque rod 7 through the connector 6 and the spline torque tube 8, and the spline torque rod 7 then transmits the torque to the stabilizing half-rod actuator module 1, and finally outputs it to the vehicle suspension, so as to achieve the purpose of adjusting the stability of the vehicle suspension;
[0044] The electromagnetic clutch input end 1.6, the electromagnetic clutch output end 1.3 and the friction plate 1.7 together constitute an electromagnetic clutch module. When the stabilizer bar needs to move, the electromagnetic clutch output end 1.3 holds the friction plate 1.7, so that the movement of the electromagnetic clutch input end 1.6 is transmitted to the output half-rod 1.1. Through the electromagnetic clutch module, the active stabilizer bar is provided with temporary decoupling capability, so that the vehicle can be temporarily decoupled under bumpy conditions, thereby improving the vehicle's passability in the face of complex road excitation and eliminating the conflict between the active stabilizer bar and the air suspension.
