POWER TRANSMISSION STRUCTURE OF WORK VEHICLE EQUIPPED WITH TOROIDAL TYPE TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To compactly construct a transmission case of a work vehicle equipped with a toroidal type transmission so as to drive narrow streets such as mountainous regions or back roads in towns and have a small turning circle in workshops. SOLUTION: A first shaft 4, a second shaft 12 and a third shaft 24 are juxtaposed at a power downstream side of a engine 1. The toroidal type transmission is constructed on the first shaft 12 and a planetary gear mechanism 18 to combine the output of the toroidal type transmission 2 is constructed on the second shaft 12. Rotation power is transmitted to the third shaft 24 driving PTO shaft 23 through a gear 13 transmitting power to the second shaft 12.
