According to a rigidity-variable anti-side-rolling torsion bar device and a method for achieving rigidity variation thereof, at least one torsion arm assembly of the torsion bar device is arranged to be a movable arm assembly, the movable arm assembly comprises a movable arm, a bearing and a backstop, the bearing and the backstop are arranged on the outer side of a torsion bar shaft in a sleeving mode, the movable arm is arranged on the outer side of the bearing and the backstop in a sleeving mode, the bearing and the torsion bar shaft are in smooth contact, an outer spline is arranged on the outer periphery, making contact with the backstop, of the torsion bar shaft, an inner spline is arranged on the inner side of the backstop, the tooth space angle of the outer spline is larger than the tooth thickness angle of the inner spline, the tooth space angle of the inner spline is larger than the tooth thickness angle of the outer spline, variable stiffness is achieved through smooth rotation between the bearing and the torsion bar shaft and idle strokes in the splines. According to the anti-side-rolling torsion bar device, variable rigidity can be achieved on a straight torsion bar device, the application range of the rigidity-variable anti-side-rolling torsion bar device is expanded, the structure of the rigidity-variable part is simple and compact, and compared with a conventional anti-side-rolling torsion bar device, the space needing to be increased is very small.

    一种刚度可变的抗侧滚扭杆装置及其实现变刚度的方法,将扭杆装置的至少一个扭转臂组件设置为活动臂组件,活动臂组件包括活动臂、轴承和止挡,轴承和止挡套设在扭杆轴外侧,活动臂套设在轴承和止挡外侧,且轴承与扭杆轴之间光滑接触,扭杆轴与止挡相接触的外侧周设有外花键,止挡内侧设有内花键,并且所述外花键的齿槽角大于所述内花键的齿厚角,所述内花键的齿槽角大于所述外花键的齿厚角,通过轴承与扭杆轴之间的光滑转动和花键内的空程来实现变刚度。本发明的抗侧滚扭杆装置可在直扭杆装置上实现变刚度,扩大了变刚度抗侧滚扭杆装置的应用范围,且实现变刚度部分的结构简单紧凑,与常规抗侧滚扭杆装置相比,需要增加的空间很小。
