The cab turnover mechanism comprises a front suspension swing arm assembly, a cab front suspension, a turnover oil cylinder, a cab and a vehicle frame, the front suspension swing arm assembly is connected with the cab front suspension, the upper end of the cab front suspension is connected with the cab, the lower end of the cab front suspension is connected with the vehicle frame, and the rear end of the cab front suspension in the vehicle advancing direction is connected with the turnover oil cylinder; when the cab begins to turn over, an oil cylinder telescopic shaft of the turning oil cylinder extends, the rear end of the cab is jacked up, the cab is turned over forwards with a pin shaft in the front overhanging swing arm assembly as the center, the front end of the front overhanging swing arm assembly moves downwards, and after the center of the cab turns over the turning shaft, the cab is turned over. Effective pressure of descending generated by the cab under the action of gravity is conducted to the frame through the front suspension swing arm assembly, and vibration impact is relieved. On the premise that the structural strength is guaranteed, the weight of a workpiece is reduced, the impact force of the structure is reduced, the risk that the cab is damaged when the cab falls back is reduced, and the stability in the overturning process is guaranteed.
本发明公开了一种驾驶室翻转机构,包括前悬摆臂总成、驾驶室前悬置、翻转油缸、驾驶室和车架,所述前悬摆臂总成与驾驶室前悬置连接,所述驾驶室前悬置上端与驾驶室连接,下端与车架连接,沿车辆前进方向的后端与翻转油缸连接;驾驶室开始翻转时,翻转油缸的油缸伸缩轴伸长,将驾驶室后端顶起,驾驶室以前悬摆臂总成中的销轴为中心向前翻转,前悬摆臂总成前端向下移动,驾驶室的中心在翻过翻转轴后,驾驶室在重力作用下产生下降的效应压力通过前悬摆臂总成传导到车架上,减缓了振动冲击。本发明在保证结构强度的前提下,降低了工件重量,减少结构的冲击力,降低了驾驶室回落时对驾驶室造成损坏的风险,保证了翻转过程的平稳性。
