The invention provides a torsion bar spring and a preparation method thereof, and belongs to the technical field of motor vehicles. The torsion rod spring comprises a spring body and two connecting shafts, wherein the two connecting shafts are connected to the end parts of the spring body correspondingly, the spring body comprises a shell and a filling rod, the shell is a conductive composite structural part, the two end parts of the shell are provided with wire connectors correspondingly, the wire connectors are used for being connected with a vehicle-mounted power supply and a vehicle-mounted current control system so as to change the rigidity of the shell by adjusting the current loaded on the shell, the filling rod is inserted into the shell in the length direction of the shell, the outer wall of the filling rod is connected with the inner wall of the shell, the torsion bar spring further comprises connector bodies corresponding to the connecting shafts in a one-to-one mode, and the connector bodies are fixedly arranged on the corresponding connecting shafts in a sleeve mode correspondingly. According to the torsion bar spring and preparation method thereof, through the torsionrod spring, the overall mass of the torsion rod spring can be reduced, and the rigidity change requirement can be met.
