The invention provides a torsion bar spring space inclined type variable stiffness decoupling suspension which comprises a stand column, a control arm structure, a push rod, a torsion bar spring, an electromagnetic clutch and a spiral spring. The control arm structure is arranged on the stand column and connected with the push rod. The torsion rod spring is connected with the push rod and the electromagnetic clutch. The electromagnetic clutch is used for being fixed to a vehicle, and the electromagnetic clutch is further connected with the spiral spring through the rotating support. When the electromagnetic clutch is powered on, the spiral spring stops working, meanwhile, the control arm structure swings to drive the push rod to move, and then the torsion rod spring is driven to twist so that the suspension can work in a high-rigidity mode. When the electromagnetic clutch is powered off, the control arm structure swings to drive the push rod to move so as to drive the torsion rod spring to twist, and then the spiral spring is driven to move so that the suspension can work in a low-rigidity mode. The suspension can work in two different rigidity modes, the vehicle handling stability is good, and therefore better riding comfort is achieved.

    本发明提供了一种扭杆弹簧空间斜置式多变刚度解耦悬架,包括立柱、控制臂结构、推杆、扭杆弹簧、电磁离合器和螺旋弹簧。控制臂结构配置在立柱上,并与推杆连接。扭杆弹簧分别与推杆和电磁离合器连接。电磁离合器用于固定在车辆上,且该电磁离合器还通过旋转支架与螺旋弹簧连接。本发明的电磁离合器通电时,螺旋弹簧停止工作,同时通过控制臂结构摆动可带动推杆运动,进而带动扭杆弹簧扭动以使悬架在高刚度模式下工作。在电磁离合器断电时,通过控制臂结构摆动可带动推杆运动以带动扭杆弹簧扭动,进而带动螺旋弹簧运动以使悬架在低刚度模式下工作。本发明的悬架可在两种不同的刚度模式下工作,且车辆操纵稳定性好,因而具有更好的乘坐舒适性。
