The invention relates to the technical field of supporting suspension, and discloses a suspension device for eliminating a truck rear wheel steering difference. The device comprises a top plate, a trigger device is fixedly mounted in the middle of the bottom of the top plate, and a coupler is movably arranged at one end of each hydraulic rod and fixedly mounted at the other end of a universal rod.When each hydraulic rod stretches out and draws back, the universal rod can be driven to move; a posture of a hub seat is changed; an included angle between the bottom of an inclined panel and the top plate is 35 degrees; an adjusting direction of the hydraulic rod can be decomposed into a horizontal component and a vertical component; the component in the horizontal direction can be used for adjusting a turning angle of a wheel; the component in the vertical direction can be used for adjusting a height of the wheel; and the hydraulic rods in the adjusting devices on the two sides of the bottom of the top plate are opposite in a movement direction so that the adjusting devices can be matched with each other to synchronously and reversely adjust the wheel postures on the two sides, a turning radius of a trailer is larger when the trailer turns along with a truck head, and a turning difference of the trailer during truck turning is eliminated.

    本发明涉及支撑悬挂技术领域,且公开了一种消除货车后轮转向差的悬挂装置,包括顶板,顶板底部的中间位置上固定安装有触发装置,液压杆的一端活动套接有联轴器,联轴器固定安装在万向杆的另一端。使液压杆进行伸缩时能够带动万向杆进行运动,从而改变轮毂座的姿态,由于斜面板底部与顶板所成夹角为三十五度,使液压杆的调节方向可分解为水平和竖直的两个分量,水平方向上的分量可以对车轮的转角进行调节,竖直方向上的分量可以对车轮的高度进行调节,又由于顶板底部两侧调节装置中的液压杆运动方向相反,实现调节装置可以相互配合对两侧的车轮姿态进行同步反向调节,使挂车在跟随车头转弯时转弯半径更大,消除了货车转弯时挂车存在转向差。
