The invention provides an anti-overturning suspension method for a heavy truck, which relates to the technical field of heavy-load automobiles and comprises the following steps: when a new energy heavy truck is started, obtaining the front, back, left and right suspension heights of a cab; when the suspension height is higher than a preset height value, the air cylinder is deflated, and when the suspension height is lower than the preset height value, the air cylinder is inflated; when the maximum suspension height difference of the cab is larger than a preset threshold value, a rear suspension air cylinder is inflated and deflated according to the pressure of the ends of the two transverse buffer rods till the pressure of the ends of the two transverse buffer rods is the same; inflating and deflating the front overhang cylinder according to the pressure of the end parts of the two longitudinal buffer rods until the pressure of the end parts of the two longitudinal buffer rods is the same; and after balance adjustment of the heavy truck is completed, normal adjustment is recovered. The left and right sides of the front suspension and the left and right sides of the rear suspension are effectively matched, the front, back, left and right suspension height values of the cab can be effectively obtained, when the cab has a balance difference, the cab is adjusted through the four sets of suspension air cylinders, and the overturning risk of a heavy truck is effectively reduced.

    本发明提供一种用于重卡的防倾覆悬置方法,涉及重载汽车技术领域,包括以下步骤:新能源重卡启动时,获取驾驶室前后左右悬置高度;在悬置高度高于预设高度值时气缸放气,在悬置高度低于预设高度值时气缸充气;驾驶室最大悬置高度差大于预定阈值时,根据两个横向缓冲杆端部的压力,对后悬气缸充放气,直至两个横向缓冲杆端部压力相同;根据两个纵向缓冲杆端部的压力,对前悬气缸充放气,直至两个纵向缓冲杆端部压力相同;重卡平衡调解完成之后,恢复正常调节。本发明前悬置左右两侧和后悬置左右两侧进行有效配合,可以有效获取驾驶室前后左右的悬置高度值,在驾驶室出现平衡差时,通过四组悬置气缸对驾驶室进行调节,有效降低重卡倾覆风险。
