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.
