The invention belongs to the technical field of engineering machinery, and particularly relates to a traction force control method, a traction force control system and an articulated dump truck. The traction force control method comprises the following steps: judging whether wheels of a drive axle slip or not, if so, further judging which drive axle slips, and judging whether the wheels on one side slip or the wheels on two sides slip, and when judging that one drive axle slips on one side, stopping the traction force control. If yes, an inter-wheel differential lock between the left half shaft and the right half shaft of the slipping drive axle is controlled to be locked; when it is judged that the wheels on the two sides of a certain drive axle slip, the inter-wheel differential lock between the left half axle and the right half axle of the slipping drive axle is controlled to be locked, and meanwhile the inter-axle differential lock between the front drive axle and the middle drive axle and the inter-axle differential lock between the front drive axle and the rear drive axle are controlled to be locked. By means of the traction force control method, the inter-wheel differential lock and/or the inter-axle differential lock can be locked at the accurate time, it is guaranteed that the vehicle can get out of trouble, and no loss is caused to the traction force control system.
本发明属于工程机械技术领域,尤其涉及一种牵引力控制方法、牵引力控制系统及铰接式自卸车。牵引力控制方法包括:判断驱动桥车轮是否打滑,若是,则进一步判断是哪个驱动桥发生车轮打滑,并判断是单侧车轮打滑还是双侧车轮打滑,当判断为某个驱动桥发生单侧车轮打滑时,则控制发生打滑的驱动桥的左半轴与右半轴之间的轮间差速锁锁止;当判断为某个驱动桥发生双侧车轮打滑时,则控制发生打滑的驱动桥的左半轴与右半轴之间的轮间差速锁锁止,同时控制前驱动桥与中驱动桥和后驱动桥之间的轴间差速锁锁止。通过上述牵引力控制方法,能够在准确的时机对轮间差速锁和/或轴间差速锁进行锁止,保证了车辆能够脱困,且不会对牵引力控制系统造成损耗。
