The invention relates to a hydraulic mechanical stepless transmission and steering device for a multi-section tracked vehicle. The hydraulic mechanical stepless transmission and steering device comprises an input system, a hydraulic system, a speed change system, a differential system, an output system and a section position switching system. The advantages of hydraulic transmission and mechanical transmission are combined into a whole, and the tracked vehicle transmission and steering system which is compact in structure, capable of achieving a large transmission ratio, large in transmission power, high in efficiency and capable of achieving stepless speed regulation is provided. In the in-situ steering working condition, multiple modes such as hydraulic steering, mechanical steering and hydraulic and mechanical double-flow steering can be achieved.
