The invention provides a rear suspension safety locking method, which relates to the technical field of new energy trucks, and comprises the following steps: when a new energy truck is started, if a cab bottom beam is clamped in a lock catch, a height valve acquires a suspension distance between a rear suspension upper beam and a rear suspension lower beam in real time; when the suspension distance is larger than a first preset threshold value, the buffer air bag is deflated; when the suspension distance is smaller than a first preset threshold value, the buffer air bag is inflated until the distance between the rear suspension upper beam and the rear suspension lower beam is stable; whether the difference value of the buffering distances of the two buffering rods is not larger than a second preset threshold value or not is judged, and if yes, the locking valve locks the cab bottom beam in the lock catch; otherwise, the operation is not executed. By means of the buffering air bag and the buffering rod in the rear suspension structure, buffering is effectively conducted in the descending process of the compartment, the safety of the compartment is effectively recognized when the compartment descends, rear suspension locking is conducted under the condition that the safety of the gravity center of the compartment is guaranteed, the cab compartment is effectively prevented from overturning, and safety is high.

    本发明提供一种后悬挂安全锁止方法,涉及新能源货车技术领域,包括以下步骤:新能源货车启动时,若锁扣内卡入有驾驶室底梁,则高度阀实时获取后悬上梁和后悬下梁之间的悬置间距;使得悬置间距大于第一预定阈值时,缓冲气囊进行放气;以及在悬置间距小于第一预定阈值时,缓冲气囊进行充气,直至后悬上梁和后悬下梁之间间距稳定;判断两个缓冲杆的缓冲距离的差值是否不大于第二预定阈值,若是则锁止阀将驾驶室底梁锁在锁扣内;反之则不执行操作。本发明通过后悬置结构中的缓冲气囊和缓冲杆,有效对车厢降下过程进行缓冲,并在车厢降下时有效识别车厢安全性,在确保车厢重心安全下进行后悬锁止,有效防止驾驶室车厢倾覆,安全性高。
