The invention discloses a track-type vehicle chassis with a variable wheelbase, and relates to the technical field of track-type vehicles. The problems that an existing crawler with a fixed chassis length cannot meet the trafficability in complex terrains, the stability under different loads and the adaptability to diversified operation scenes are solved. A front frame compartment and a rear frame compartment are arranged below a wheel base adjusting mechanism, two crawler belt adjusting mechanisms are arranged on the two sides of the wheel base adjusting mechanism respectively, a wheel base adjusting executing assembly is installed at the lower end of a bottom plate and connected with two connecting plates, and the front frame compartment and the rear frame compartment are installed at the lower ends of the two connecting plates. The axle distance adjusting execution assembly drives the front frame compartment and the rear frame compartment to move inwards or outwards at the same time, the axle distance of a vehicle chassis is adjusted, and the driving wheel transmission execution assembly and the driven wheel transmission execution assembly are installed in the front compartment body and the rear compartment body respectively. The wheel base can be flexibly adjusted to change the length of the chassis according to actual working conditions, and various complex working environments and task requirements are met.

    一种可变轴距的履带式车辆底盘,它涉及履带车辆技术领域。本发明解决了现有的固定底盘长度履带车存在难以满足车辆在复杂地形中的通过性、不同载荷下的稳定性及其对多样化作业场景的适应性的问题。本发明的轴距调整机构下方设有前、后车架厢,两组履带调整机构分别布置在轴距调整机构两侧,底板下端安装轴距调整执行组件,轴距调整执行组件连接两个连接板,两个连接板下端安装前、后车架厢,轴距调整执行组件带动前车架厢和后车架厢同时向内或向外移动,实现车辆底盘轴距的调节,前、后厢体内部分别安装驱动轮、从动轮传动执行组件。本发明可根据实际工况灵活调整轴距改变底盘长度,用于适应多种复杂作业环境与任务需求。
