The embodiment of the invention provides a chassis and engineering machinery, which relate to the technical field of engineering machinery. The chassis comprises a frame, a positioning assembly, a driving piece, a first support and a second support, wherein the positioning assembly is installed on the frame, the first support and the second support are arranged on the two sides of the frame respectively and connected with the frame, the driving piece is connected with the first support and the second support respectively, and the positioning assembly is connected with the first support and thesecond support respectively; the driving piece is used for driving the first support and the second support to move away from or close to each other; the positioning assembly is used for keeping thedistance between the first support and the frame equal to the distance between the second support and the frame. In the embodiment of the invention, the frame is prevented from moving back and forth in the working process, and the working stability of the chassis under any width is ensured.
本发明的实施例提供了一种底盘及工程机械,涉及工程机械技术领域。底盘包括车架、定位组件、驱动件、第一支架及第二支架,定位组件安装在车架上,第一支架与第二支架分别设置在车架的两侧,并与车架连接,驱动件分别与第一支架及第二支架连接,定位组件分别与第一支架及第二支架连接;驱动件用于驱动第一支架及第二支架向远离或靠近对方的方向运动;定位组件用于保持第一支架与车架之间的距离和第二支架与车架之间的距离相等。在本发明实施例中,避免在工作过程中车架来回窜动,确保底盘在任何宽度下工作的稳定性。
