Special mechanical transmission telescopic door type axle of high-ground-clearance machinery

The invention provides a special mechanical transmission telescopic door type axle of high-ground-clearance machinery. The mechanical transmission telescopic door type axle mainly comprises a cross beam, a vertical shaft frame, vertical shafts with steering transmission, wheel hub reducers, wheels, right-angle boxes, transmission shafts, a differential transmission device, steering arms, a steering oil cylinder and a wheel tread adjustment oil cylinder. The special mechanical transmission telescopic door type axle of high-ground-clearance machinery is compact in structure, reasonable in configuration, high in ground clearance, high in mechanical transmission reliability and low in maintenance cost, has functions of steering, driving and wheel tread adjustment, and can be mounted on common high-ground-clearance machinery in a matched manner and mounted on special high-ground-clearance machinery with four-wheel steering, four-wheel driving and wheel tread adjustment, thus having a wide application range.
