The vehicle body height adjusting device for the trailer axle comprises a piston cylinder, a piston plate is vertically connected into the piston cylinder in a sealed and sliding mode, the piston plate divides the interior of the piston cylinder into a first buffer area and a second buffer area from top to bottom, and the first buffer area and the second buffer area are both filled with hydraulic oil; the invention discloses a vehicle body height adjusting method for a trailer axle. The vehicle body height adjusting method mainly comprises the following steps: S1, assembling; s2, calibration is carried out; s3, buffer adjustment; and S4, cooling. According to the invention, through the arrangement of the first driving mechanism and the second driving mechanism, the conduction area between the first through hole and the first liquid discharge pipe and the conduction area between the second through hole and the second liquid discharge pipe can be adjusted, so that the flowing resistance of hydraulic oil in the first liquid discharge pipe and the second liquid discharge pipe is changed; and therefore, the height of the axle can be automatically buffered and adjusted according to the vibration intensity of the axle, and the stability of the axle is improved.

    本发明公开了一种用于挂车车桥的车身高度调节装置,包括活塞筒,所述活塞筒内竖直密封滑动连接有活塞板,且活塞板将活塞筒内部由上至下分隔为第一缓冲区和第二缓冲区,所述第一缓冲区和第二缓冲区内均填充有液压油;一种用于挂车车桥的车身高度调节方法,主要包括以下步骤:S1、组装;S2、校准;S3、缓冲调节;S4、冷却。本发明中,通过设置第一驱动机构和第二驱动机构,可以对第一通孔和第二通孔与第一排液管和第二排液管之间导通面积进行调节,从而改变第一排液管和第二排液管内液压油流动的阻力大小,进而可以根据车桥受到的震动强度大小自动对车桥的高度进行缓冲调节,提高了车桥的稳定性。
