The invention provides a crawler belt assembly and engineering machinery, the crawler belt assembly is installed on a frame, the crawler belt assembly comprises a driving wheel set, a tensioning wheel, a tensioning assembly and a crawler belt, and the driving wheel set is connected with the frame; in the moving direction, the tensioning wheel is arranged on the front side of the driving wheel set. One end of the tensioning assembly is connected with the frame, and the other end is connected with the tensioning wheel; the crawler belt is arranged on the circumferential outer sides of the driving wheel set and the tensioning wheel in a sleeving manner; the tensioning wheel is movably connected with the tensioning assembly so that the position of the tensioning wheel can be changed in the vertical direction when the crawler assembly moves. In this way, when the engineering machine provided with the crawler belt assembly encounters a protrusion or a recess in the moving process, the position of the tensioning wheel and the position of the driving wheel set can be changed in the vertical direction, the tensioning wheel can drive the crawler belt arranged on the outer side of the circumferential direction of the tensioning wheel to move upwards or downwards, and therefore inclination and shaking of the whole vehicle body are slowed down, and the service life of the vehicle body is prolonged. Therefore, inclination and shaking of operators in the cab are slowed down, and the stability of the engineering machinery during movement is improved.
本申请提供了一种履带组件及工程机械,履带组件安装于车架上,履带组件包括驱动轮组、张紧轮、张紧组件及履带,驱动轮组与车架连接;在移动方向上,张紧轮设置于驱动轮组的前侧;张紧组件一端与车架连接,另一端与张紧轮连接;履带套设于驱动轮组和张紧轮的周向外侧;张紧轮与张紧组件活动连接,以使张紧轮在履带组件移动时,能够在竖直方向上发生位置改变。这样当设置有该履带组件的工程机械在移动过程中遇到凸起或凹陷时,张紧轮能够在竖直方向上与驱动轮组的位置发生改变,张紧轮会带动设置于张紧轮周向外侧的履带向上或向下位移,从而减缓车身整体的倾斜和晃动,进而减缓驾驶室的操作人员的倾斜和晃动,提升工程机械移动时的稳定性。
