The invention relates to a nonlinear seat suspension. The nonlinear seat suspension comprises a lower frame, an upper frame, a first connecting rod and a second connecting rod which are arranged between the lower frame and the upper frame, an adjusting rod arranged in the upper frame, a hand wheel arranged at one end of the upper frame for driving the adjusting rod to rotate, main springs arranged at the two sides of the adjusting rod, a first sliding block and a second sliding block arranged at one end of the main springs, a first boss arranged on the second sliding block, a torsion bar arranged on the upper frame, a second boss arranged on the torsion bar, and a third connecting rod of which the two ends are hinged to the first sliding block and the first connecting rod respectively. The middle of the first connecting rod is hinged to the middle of the second connecting rod. Negative rigidity is achieved through the torsion bar, and force acting on the upper frame and displacement of the upper frame are nonlinear through cooperation of the torsion bar and the main spring; the structure is simple, low-frequency vibration caused by the working environment can be effectively isolated, and therefore the body health of the driver is guaranteed.
本发明涉及一种非线性座椅悬架,包括下框架、上框架、设置于下框架和上框架之间的第一连杆和第二连杆、设置于上框架中的调整杆、设置于上框架一端驱动调整杆转动的手轮、设置于调整杆两侧的主弹簧、设置于主弹簧一端的第一滑块和第二滑块、设置于第二滑块上的第一凸台、设置于上框架上的扭杆、设置于扭杆上的第二凸台以及两端分别与第一滑块和第一连杆铰接的第三连杆;第一连杆的中部和所述第二连杆的中部铰接。本发明通过所述扭杆实现了负刚度,通过扭杆与主弹簧的配合,使作用于上框架的力与所述上框架的位移为非线性;结构简单,可以有效隔离由于工作环境引起的低频振动,从而保证了驾驶员的身体健康。
