The invention discloses an anti-side-rolling system without a torsion bar shaft, the anti-side-rolling system comprises two independent anti-side-rolling devices which are respectively arranged between bogies on two sides of a train and a carriage, each anti-side-rolling device comprises a connecting rod piece, a torsion arm, an outer shell and a torsion shaft, one section of the torsion shaft is positioned in the inner space of the outer shell, and the other section of the torsion shaft is positioned in the inner space of the outer shell. An elastic torsion piece is arranged between the periphery of the torsion shaft and the inner wall of the outer shell, so that the torsion shaft has elastic torque larger than zero when rotating, the outer shell is fixed to a bogie, the outer end of the torsion shaft is fixedly connected with one end of a torsion arm perpendicular to the torsion arm, the other end of the torsion arm is rotatably connected with the lower end of a connecting rod piece, and the upper end of the connecting rod piece is connected with a compartment. When the distance between the carriage on one side and the bogie is changed, the elastic torsion piece in the anti-side-rolling device on the side provides elastic resistance for resisting the change of the distance. The bogie has the advantages that a torsion bar shaft is omitted in the middle, so that other parts on the bogie can be freely arranged; and if the anti-side-rolling torsional rigidity is improper, the anti-side-rolling torsional rigidity can be conveniently assembled, disassembled and replaced.
本发明公开了一种无扭杆轴的抗侧滚系统,由分别安装在列车两侧转向架与车厢之间的独立的两个抗侧滚装置组成,每个抗侧滚装置包括连杆件、扭转臂、外壳体和扭转轴,扭转轴的一段位于外壳体的内空间,其外周与外壳体的内壁之间设有弹性扭转件,使扭转轴转动时具有大于零的弹性扭矩,外壳体固定在转向架上,扭转轴的外端与扭转臂的一端垂直于扭转臂固定连接,扭转臂的另一端与连杆件的下端可转动连接,连杆件的上端与车厢连接,当一侧车厢与转向架之间的间距发生变化时,由所在侧的抗侧滚装置中的弹性扭转件提供抵抗该间距变化的弹性阻力。其优点在于:中间免去了扭杆轴的设置,使得转向架上其他部件能够自由布设;若发现抗侧滚扭转刚度不合适,能够方便地装拆更换。
