The invention relates to the technical field of damping devices, and provides an automobile damping suspension device which comprises a damper and a spiral spring, the damper comprises a working cylinder barrel and a piston rod axially and movably connected to the working cylinder barrel, and the peripheral side of the working cylinder barrel is fixedly sleeved with a fixed carrying table; the peripheral side of the piston rod is sleeved with a rotary carrying table and a movable carrying table, the rotary carrying table is rotationally arranged on the piston rod, and a rotary driving mechanism is arranged between the rotary carrying table and the piston rod; the movable carrying table is located between the fixed carrying table and the rotary carrying table, the movable carrying table is axially arranged on the piston rod in a sliding mode, and the spiral spring is arranged between the fixed carrying table and the movable carrying table; and a rotary lifting mechanism is arranged between the movable carrying table and the rotary carrying table. On the basis, the elastic force of the spiral spring in the initial state can be adaptively adjusted, so that the elastic force of the spiral spring can be correspondingly changed under the condition that different numbers of passengers are carried, and the situation that an automobile bumps greatly during driving due to the fact that the elastic force of the spiral spring is too large is reduced.
本申请涉及减震装置技术领域,提供了一种汽车减震悬挂装置,包括减震器和螺旋弹簧,减震器包括工作缸筒以及轴向活动连接于工作缸筒的活塞杆,工作缸筒的外周侧固定套设有固定载台;活塞杆的外周侧套设有旋转载台和活动载台,旋转载台转动设置于活塞杆,且旋转载台与活塞杆之间设有旋转驱动机构;活动载台位于固定载台与旋转载台之间,活动载台轴向滑动设置于活塞杆,螺旋弹簧设置于固定载台与活动载台之间;活动载台与旋转载台之间设有旋转升降机构。基于此,能够对螺旋弹簧初始状态下的弹力大小进行适应性调整,使得在搭载不同数量乘客的情况下螺旋弹簧的弹力能够相应变化,减少由于螺旋弹簧弹力过大而造成汽车驾驶时大幅度颠簸的情况。
