The invention provides a steering control system and an operation machine. The steering control system comprises a rear axle steering transmission rod system, a telescopic device, a steering information obtaining unit and a driving device. The telescopic device is provided with a telescopic rod hinged to the rear axle steering transmission rod system, and the driving device is used for controlling the telescopic rod to do telescopic motion or not according to rear axle steering information. According to the arrangement, when all the rear axles steer, the driving device controls the telescopic rod to do corresponding telescopic motion according to current steering information, and the rear axle steering transmission rod system is driven to move. And when each rear axle cannot steer, the driving device controls the telescopic rod not to stretch out and draw back, and the rear axle steering transmission rod system is locked. In this way, steering of all the rear axles is achieved through transmission connection of the mechanical rod system, various steering modes during driving can be met by controlling movement of the telescopic rod, the structure is simple, use of parts is greatly reduced, the production cost is reduced, and the reliability and accuracy of the steering angle relation during steering of all the rear axles are effectively improved.
本发明提供一种转向控制系统及作业机械,包括后桥转向传动杆系、伸缩装置、转向信息获取单元和驱动装置。伸缩装置设有与后桥转向传动杆系铰接的伸缩杆,驱动装置用于根据后桥转向信息控制伸缩杆是否作伸缩运动。如此设置,当各后桥转向时,驱动装置根据当前转向信息控制伸缩杆作相应的伸缩运动,带动后桥转向传动杆系运动。当各后桥不能转向时,驱动装置则控制伸缩杆不能进行伸缩,将后桥转向传动杆系锁止。这样各后桥的转向通过机械杆系传动连接和实现,而且通过控制伸缩杆的运动能够满足行驶时的多种转向模式,结构简单,大大减少了零部件的使用,降低生产成本,有效提升了各后桥转向时转角关系的可靠性和准确性。
