Problems solved by technology
However, the diverter mechanism and the steering mechanism in the hydromechanical differential steering system are hydraulically controlled, requiring high-precision, high-power hydraulic components, which makes the tracked vehicles equipped with this steering system costly to manufacture and use. Currently, it is used on domestic tracked vehicles also subject to certain restrictions

The invention relates to a stepless steering system for a crawler, comprising a splitting mechanism, a non-stop mechanism and a steering mechanism, wherein the splitting mechanism is provided with an input end and two output ends, the input end is connected with a corresponding power source, and the two output ends are respectively connected with the non-stop mechanism and the steering mechanism; the splitting mechanism comprises a splitting planetary line which is composed of a planetary gear transmission mechanism, and the planetary gear transmission mechanism is provided with three elements, namely a sun gear, a gear ring and a planet carrier; and one of the elements is a power input element which is used as the input end of the splitting mechanism, the other two elements are power output elements which can be respectively braked by brake mechanisms, and the two power output elements are used as the two output ends of the splitting mechanism. With the adoption of the mechanical splitting mechanism, the machining difficulty and manufacturing cost of the existing hydraulic mechanical differential steering system are reduced.
Description
technical field [0001] The invention relates to a mechanical stepless steering system for tracked vehicles. Background technique [0002] The development of the steering system of tracked vehicles has roughly gone through steering clutches and hydromechanical differential steering systems. [0003] The steering clutch is a multi-disc friction clutch, which transmits torque by the friction force of the friction surface. When the steering clutch on one side is disengaged, the torque transmitted by the driving wheel on this side can be reduced or cut off, so that the tracked vehicle can turn. Because of its simple structure and convenient manufacture, it has been widely used in early medium and small tracked vehicles. However, due to its low production efficiency and high energy consumption, the application of the steering clutch is limited to a certain extent with the continuous increase of the power of the tracked vehicle. [0004] The hydraulic-mechanical differential stee...
