<p><P>PROBLEM TO BE SOLVED: To provide a toroidal continuously variable transmission type working vehicle securing responsiveness when rapid operation to a reverse side is performed during forward traveling. <P>SOLUTION: The toroidal continuously variable transmission type working vehicle includes a toroidal transmission section (4) with a planetary mechanism converting and outputting variable speed power and differential power, and a high and low switching clutch (30) transmitting the variable speed power for a forward medium and high speed range and transmitting the differential power including a stop speed to a running system for a forward and reverse low speed range. As a rotation speed difference between the variable speed power and the differential power, which forms a switching condition from the former to the latter in the high and low switching clutch (30), there are provided a first acceptable limit difference and a second acceptable limit difference larger than the first acceptable limit difference. The first acceptable limit difference is applied to switching at a deceleration within a predetermined range and the second acceptable limit difference is applied to switching at rapid deceleration corresponding to switching to reverse traveling by momentary operation of a forward and reverse selection lever (K). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
