Abstract

PURPOSE: A continuously variable transmission enables the continuously variable speed change on the total range of speeds such as reverse, neutral and maximum advance speeds. CONSTITUTION: A CVT(continuously variable transmission) has two power transmission paths. One is a path from an input shaft(1) to an element2(2) where there is no speed change. The other is a path from an element3(3) to an element5(5) where there are various speed changes by the CVT. The two paths are combined to an element6(6) of a planetary gear set, thereby making one output terminal. The main speed change portion of the CVT is applied on the element2(2) and element3(3). Thus, the CVT makes the total range of speed changes as a continuously variable speed change type.

The transmission line constitutes two power transmission paths, and these two lines are connected to the planetary gear set as elements 2 and 5, again by the element 6 of the planetary gear set. It is a structure that is finally output to the output shaft 7 by combining the lines of. The power of one line is divided into two lines, and the divided two lines are output again as one line.
