Torsion bar suspension

The utility model discloses a torsion bar suspension which comprises a first support, a second support, a third support and a fourth support. One side of the second support is connected with the auxiliary frame; one side of the hydraulic mechanism is connected with the other side of the first support, the other side of the hydraulic mechanism is connected with the other side of the second support, and the hydraulic mechanism is used for providing damping. The damping of the torsion bar suspension is increased by additionally arranging the hydraulic mechanism, the impact vibration enhancing speed is high, shaking is avoided under the gear shifting, ignition and flameout working conditions, meanwhile, the hydraulic mechanism does not need to be installed in an auxiliary frame, the space of the auxiliary frame is not occupied, and shock isolation is facilitated. 本申请公开了一种扭力杆悬置，包括：第一支架，所述第一支架的一侧和变速器连接；第二支架，所述第二支架的一侧和副车架连接；液压机构，所述液压机构的一侧和所述第一支架的另一侧连接，所述液压机构的另一侧和所述第二支架的另一侧连接，用于提供阻尼。通过增加液压机构增大扭力杆悬置的阻尼，进而冲击振动增强速度较快、换挡
