Abstract

PURPOSE: To automatically prevent a work vehicle from any damage caused by an unreasonable operation by providing a driving side actuating member of a stepless variable speed gear with a hydraulic cylinder with a feed-back type oil pressure controlling circuit in a side-by-side relation.
CONSTITUTION: When an overload is applied onto an automatic load controller for a work vehicle, a V-belt 13, which is provided between a pulley 12 mounted on an output shaft 11 and a pulley 29 mounted on an input shaft 28, is tensioned and a tension pulley 33, which is a load detector, is pushed forward against the force of spring 34. Then, the oil pressure in an oil chamber 16b of a cylinder 16 is decreased via a variable throttle valve 24, so that a piston moves to the decreased pressure side, the channel width of a counter pulley 4 is widened, the input shaft 28 is rotated at a low speed by a stepless speed change gear, which are constituted by the pulley 4, an input pulley 6 and a V-belt 7, and thereby the output shaft 11 is rotated at a low speed.
