The crawler chassis comprises a frame (1), a first crawler frame (2), a second crawler frame (3), a first driving device (4) and a second driving device (5), the first driving device (4) is arranged between the frame (1) and the first crawler frame (2) and is configured to drive the first crawler frame (2) to stretch out and draw back in the first direction relative to the frame (1), and the second driving device (5) is configured to drive the second crawler frame (3) to stretch out and draw back in the second direction relative to the frame (1). The second driving device (5) is arranged between the frame (1) and the second track frame (3) and is configured to drive the second track frame (3) to stretch out and draw back relative to the frame (1) in the first direction so as to adjust the distance between the first track frame (2) and the second track frame (3) in the first direction. The distance between the first crawler frame and the second crawler frame can be adjusted in the first direction through the first driving device and the second driving device, so that the width of the whole crawler chassis is adjusted, and the requirements of operation and transition in a narrow space are met.

    本发明涉及一种履带底盘和工程车辆,其中履带底盘包括车架(1)、第一履带架(2)、第二履带架(3)、第一驱动装置(4)和第二驱动装置(5),第一驱动装置(4)设置于车架(1)和第一履带架(2)之间并被配置为驱动第一履带架(2)相对于车架(1)沿第一方向伸缩,第二驱动装置(5)设置于车架(1)和第二履带架(3)之间并被配置为驱动第二履带架(3)相对于车架(1)沿第一方向伸缩,以调节在第一方向上第一履带架(2)和第二履带架(3)之间的距离。本发明通过第一驱动装置和第二驱动装置可以实现在第一方向上对第一履带架和第二履带架之间距离的调节,从而实现整个履带底盘的宽度调节,满足狭窄空间作业和转场的需求。
