The invention relates to the technical field of vehicles, and particularly discloses a stabilizer bar, an auxiliary frame assembly and a vehicle. One end of the first torsion bar is coaxially connected to one end of the rigidity adjusting assembly; one end of the second torsion bar is coaxially connected to the other end of the rigidity adjusting assembly; wherein the rigidity adjusting assembly is configured to selectively adjust the coupling state of the first torsion bar and the second torsion bar, the coupling state comprises a full coupling state, a semi-coupling state and a decoupling state, and when the coupling state is the full coupling state, the first torsion bar and the second torsion bar synchronously rotate; in the semi-coupling state, the first torsion bar and the second torsion bar relatively rotate with damping force; when the transverse stabilizer bar is in the decoupling state, the first torsion bar and the second torsion bar rotate freely without damping force, so that the rigidity of the transverse stabilizer bar is actively adjusted under different road working conditions of the vehicle, and the comfort and the driving stability of the vehicle are improved.

    本发明涉及车辆技术领域,具体公开了一种稳定杆、副车架总成及车辆,稳定杆包括刚度调节组件;第一扭力杆,第一扭力杆一端同轴联接于刚度调节组件一端;第二扭力杆,第二扭力杆一端同轴联接于刚度调节组件另一端;其中,刚度调节组件被配置为可选择性调节第一扭力杆与第二扭力杆的耦合状态,耦合状态包括:全耦合状态、半耦合状态以及解耦状态,当为全耦合状态,第一扭力杆与第二扭力杆同步旋转;当为半耦合状态,第一扭力杆与第二扭力杆具有阻尼力地相对旋转;当为解耦状态,第一扭力杆与第二扭力杆无阻尼力自由地旋转,实现车辆在不同道路工况主动地调节横向稳定杆的刚度,改善车辆的舒适性和行驶稳定性。
