The invention relates to a torsion rod spring and a control method thereof and a vehicle, the torsion rod spring comprises a first rod section (1), a second rod section (2), a connecting structure (3) and a rigidity adjusting mechanism, an axial first end portion (11) of the first rod section abuts against an axial second end portion (21) of the second rod section in an attached mode, and the connecting structure is connected between the first end portion and the second end portion. The connecting structure (3) can be switched between a first connecting position and a second connecting position, and at the first connecting position, the connecting structure (3) limits rotation of the first rod section (1) relative to the second rod section (2); and at the second connecting position, the connecting structure (3) allows the first rod section (1) to rotate relative to the second rod section (2), and the rigidity adjusting mechanism can adjust the pressing force between the first end part (11) and the second end part (21). According to the torsion rod spring, the rigidity of the torsion rod spring can be constant and adjustable, and the technical problem that the rigidity of the torsion rod spring cannot be adjusted is solved.

    本公开涉及一种扭杆弹簧及其控制方法和车辆,扭杆弹簧包括第一杆段(1)、第二杆段(2)、连接结构(3)以及刚度调节机构,第一杆段轴向的第一端部(11)贴合地抵接于第二杆段轴向的第二端部(21),连接结构连接在第一端部和第二端部之间,并能够在第一连接位置和第二连接位置之间切换,在第一连接位置,连接结构(3)限制第一杆段(1)相对于第二杆段(2)转动;在第二连接位置,连接结构(3)允许第一杆段(1)相对于第二杆段(2)转动,并且刚度调节机构能够调节第一端部(11)与第二端部(21)之间的压紧力。该扭杆弹簧能够兼顾自身刚度的恒定以及刚度的可调,解决自身刚度不可调节的技术问题。
