The invention relates to the technical field of truck suspensions, in particular to a drive axle left-right interconnection suspension which comprises a damping cavity, a damping cavity piston rod, a piston, an oil conveying pipe, a molecular spring hydraulic cavity, a molecular spring piston rod, a sealing ring, a molecular spring cavity and a molecular spring. The damping cavity is filled with hydraulic oil, and the damping cavity piston rod drives the piston to reciprocate in the damping cavity to generate damping force. The top of the damping cavity piston rod is connected with a frame; the oil conveying pipe is used for transmitting pressure of the hydraulic oil cavity to the molecular spring hydraulic cavity; when the damping cavity piston rod moves downwards, the molecular spring piston rod moves into the molecular spring cavity; on the contrary, the molecular spring piston rod moves into the molecular spring hydraulic cavity under the action of the elastic restoring force of the molecular spring. The molecular spring is used for the automobile suspension, the molecular spring can achieve left-right interconnection of suspension elastic elements, and therefore a new structure is provided for the automobile interconnection suspension.
本发明涉及卡车悬架技术领域,具体的涉及一种驱动桥左右互联悬架,其包括阻尼腔、阻尼腔活塞杆、活塞、输油管、分子弹簧液压腔、分子弹簧活塞杆、密封圈、分子弹簧腔和分子弹簧;阻尼腔内充满液压油,阻尼腔活塞杆带动活塞在阻尼腔内往复运动时产生阻尼力;阻尼腔活塞杆顶部与车架连接;输油管用于把液压油腔的压力传递到分子弹簧液压腔;阻尼腔活塞杆向下运动时,分子弹簧活塞杆向分子弹簧腔内移动;反之,分子弹簧活塞杆受到分子弹簧的弹性回复力作用向分子弹簧液压腔内移动。本发明用于汽车悬架,分子弹簧能够实现悬架弹性元件的左右互联,从而为汽车互联悬架提供一种新的构型。
