The invention provides an anti-side-rolling torsion bar device and a vehicle, and relates to the technical field of rail transit vehicles. The anti-side-rolling torsion bar device comprises a torsion bar shaft; each rotating arm assembly comprises a mounting sleeve, a rotating shaft and a rotating shaft; the first end of the mounting arm is connected to the mounting sleeve, and the second end of the mounting arm is suitable for being rotationally connected with the connecting seat; the two expansion sleeves are installed between the two ends of the torsion bar shaft and the inner walls of the two installation sleeves respectively, and the expansion sleeves are constructed to fixedly connect the torsion bar shaft with the installation sleeves in a radial expansion mode; and the two supporting seats are rotationally connected with the two ends of the torsion bar shaft correspondingly and are suitable for being fixedly connected with a vehicle body chassis. The mounting sleeve and the torsion bar shaft are fixedly connected through radial expansion generated by the expansion sleeve, and when a vehicle rolls laterally, the side rolling resistance of the vehicle is improved, the side rolling angle of the vehicle is limited, and the transverse stability and the side rolling resistance of the vehicle are enhanced.
本公开提供了一种抗侧滚扭杆装置及车辆,涉及轨道交通车辆技术领域。抗侧滚扭杆装置包括:扭杆轴;两个转臂组件,每个转臂组件包括:安装套筒;以及安装臂,安装臂的第一端连接至安装套筒,安装臂的第二端适用于与连接座转动连接;两个胀紧套,分别安装在扭杆轴的两端和两个安装套筒的内壁之间,胀紧套被构造成通过径向胀紧的方式将扭杆轴与安装套筒固定连接;以及两个支撑座,分别与扭杆轴的两端转动连接,且适用于与车体底架固定连接。通过胀紧套产生径向膨胀以将安装套筒和扭杆轴固定连接,当车辆发生侧滚运动时,增加车辆抗侧滚强度,限制车辆侧滚角度,增强车辆的横向稳定性和抗侧滚能力。
