The invention provides an automatic lock shaft retaining mechanism, which belongs to the technical field of traffic transportation, and comprises a chassis fixing part, a lock rod and an axle connecting part, the chassis fixing part comprises a first state and a second state, the road wheels are arranged at the normal driving positions when the chassis fixing part is in the first state, and the road wheel shafts are lifted to the lifting positions from the driving positions when the chassis fixing part is in the second state; one end of the lock rod is movably connected with the underframe fixing part, and the other end of the lock rod is rotationally connected with the axle connecting part. Through the mechanical locking function of the chassis fixing part and the lock rod, rapid switching and reliable positioning of the road axle between a normal driving position and a lifting position are achieved, the whole lock shaft retaining mechanism is arranged between longitudinal beams of a vehicle chassis, the installation space can be fully utilized, the locking gap can be flexibly adjusted, locking can be achieved after the axle is lifted in place, and the locking effect is good. The ground clearance of the wheels is effectively ensured, and the reliability and safety of transportation are improved.
本发明提供一种自动锁轴保持机构,属于交通运输技术领域,包括:底架固定部、锁杆和车轴连接部;底架固定部包括第一状态和第二状态,底架固定部在第一状态下公路车轮置于正常行驶位,底架固定部在第二状态下公路轮轴由行驶位上提至提升位;锁杆的一端与底架固定部活动连接,锁杆的另一端与车轴连接部转动连接。本发明通过底架固定部与锁杆的机械锁止功能实现公路轮轴在正常行驶位与提升位之间快速转换及可靠定位,整个锁轴保持机构布置在车辆底架纵向梁之间,既可充分利用安装空间,实现锁止间隙灵活可调,又能在车轴提升到位后锁止,有效确保车轮离地高度,提高了运输的可靠性和安全性。
