スキツドステアリング機構。 A reversing gear mechanism for skid steering is arranged on the final reduction shafts 6L and 6R of the lower stage of the transmission equipped with a hydraulic clutch type transmission, a hydraulic steering clutch device, and a hydraulic steering brake device,
In a configuration in which interlining rotation is possible by changing the reduction gear 1 on the final reduction shafts 6L and 6R and the side bevel gear 3 of the reversing gear mechanism from a loosely fitted state to an engaged state by a hydraulic clutch device, the hydraulic clutch device is used. The hydraulic pressure that presses and disconnects the hydraulic steering clutch device is also used as the pressure oil of the automatic steering valve 36, and at the same time as the skid steering valve 40 is switched to operate the hydraulic clutch, the automatic steering is performed. A skid steering mechanism characterized in that it is configured to rotate the interlining by also switching the valve 36.
