Linkage structure null of the nosewheel change gears clutch feature in the riding job

摘要

PURPOSE: To improve the travelling performance in a wet puddy field by reducing resistance of a bottom of machine during travelling in the wet puddy field, surely prevent a poor operation caused by adhering muddy soil or catching small stones, etc., to a buffer spring and improve the reliability of transmission function by affecting a energisation power of the buffer spring directly. ;CONSTITUTION: A linking structure of a front wheel transmission clutch mechanism on a riding working machine is constituted by installing a buffer spring 46 on the shifter shaft 37 of a transmission clutch mechanism 27, in providing the buffer spring 46 for avoiding a shock due to transmission in a linking route, where the transmission clutch mechanism 27 capable of forcing to produce a constant rotation difference according to a pivoting direction of the machine, is linked with a pitman arm 42 in between the left and right front wheels, so as to change speed according to the pivoting operation of the machine automatically.;COPYRIGHT: (C)1995,JPO
