The invention belongs to the technical field of engineering machinery, and particularly relates to an engineering machinery traveling driving system and engineering machinery. The engineering machinery running driving system comprises a left driving assembly, a right driving assembly and a left driving assembly, wherein the left driving assembly comprises a left running pump and a left motor mechanism which are connected through an oil path; the right driving assembly comprises a right driving pump and a right motor mechanism which are connected through an oil path; the two ends of the differential lock assembly are connected with a first advancing high-pressure valve port of the left traveling pump and a second advancing high-pressure valve port of the right traveling pump through oil ways correspondingly, and the differential lock assembly can make the first advancing high-pressure valve port and the second advancing high-pressure valve port communicated. And a controller. The differential lock assembly can be controlled to be switched on or switched off according to the running state of the engineering machinery, so that left and right self-adaptive oil flow distribution is achieved during high-speed gear running to prevent pressure building, the left and right driving wheels are independently driven during low-speed gear running to prevent slipping, hydraulic elements are prevented from being damaged, tire abrasion is delayed, and the service life of the engineering machinery is prolonged. And the maintenance cost of the engineering machinery can be reduced.

    本发明属于工程机械技术领域,具体涉及工程机械行驶驱动系统和工程机械。工程机械行驶驱动系统包括:左驱动组件,包括通过油路连接的左行驶泵和左马达机构;右驱动组件,包括通过油路连接的右行驶泵和右马达机构;差速锁组件,两端分别通过油路与左行驶泵的第一前进高压阀口以及右行驶泵的第二前进高压阀口连接,差速锁组件能够使第一前进高压阀口与第二前进高压阀口之间导通;控制器。本发明能够根据工程机械的行驶状态控制差速锁组件导通或关闭,以在高速挡行驶时实现左右自适应分配油液流量以防止憋压,而在低速挡行驶时独立驱动左右两个驱动轮行驶以防止打滑,以防止液压元件损坏,并延缓轮胎磨损,有利于降低工程机械的维修成本。
