TOROIDAL CONTINUOUS VARIABLE TRANSMISSION TRACTOR

摘要

PROBLEM TO BE SOLVED: To provide a toroidal continuously variable transmission tractor with a control part for controlling a travelling speed to carry out working travel while suppressing the influences of a load change due to the working start of a ground working machine for stable working travel. SOLUTION: The toroidal continuously variable transmission tractor comprises the control part C for controlling the variator ratio of a speed control toroidal mechanism 5a for the tractor T to carry out working travel. The control part C controls a change of the variator ratio in relation to the working start of the ground working machine R. COPYRIGHT: (C)2007,JPO&INPIT
