The invention relates to a truck cab suspension structure, and belongs to the technical field of vehicle suspension, the truck cab suspension structure comprises a locking mechanism, and the locking mechanism comprises a first-stage locking mechanism and a second-stage locking mechanism which are arranged on a rear suspension upper support and used for locking a cab; the limiting mechanism comprises a limiting column and a safety limiting bolt, wherein the limiting column is arranged on the rear suspension lower support and matched with the first-stage locking mechanism for locking, and the safety limiting bolt is matched with the second-stage locking mechanism for locking. Impact can be resisted through the first-stage locking mechanism, the cab is prevented from being separated from the frame, after the first-stage locking mechanism loses efficacy and is broken, the second-stage locking mechanism still enables the cab to be connected with the frame, the insurance effect is achieved, and the situation that only one connecting mechanism is arranged between the cab and the frame, so that the cab is damaged is avoided. And after failure is caused, the cab is completely separated from the frame, so that the connecting effect of the rear suspension mechanism is improved, the service life of the rear suspension mechanism is prolonged, and the safety of a driver is improved.

    本申请涉及一种货车驾驶室悬置结构,属于车辆悬置技术领域,所述货车驾驶室悬置结构,包括所述锁止机构包括设置于后悬上支架上用于锁止驾驶室的一级锁止机构和二级锁止机构,所述限位机构包括设置于后悬下支架上与一级锁止机构配合锁止的限位柱和与二级锁止机构配合锁止的保险限位栓;本申请可以通过一级锁止机构对抗冲击,避免驾驶室与车架分离,在一级锁止机构失效断裂后,二级锁止机构依然使驾驶室与车架之间连接,起到保险的作用,避免只有驾驶室与车架之间只有一个连接机构,导致失效后会使驾驶室与车架完全脱离,提高了后悬机构的连接效果,提高了后悬机构的寿命,且提高了对驾驶人员的安全性。
