Abstract
A reversing gearset of a continuously variable transmission, in particular a continuously variable belt transmission has a drive input shaft (6), a primary shaft (10), a simple planetary gearset with a sun gear (2), a web (3) for the planetary gears (4) and an annular gear (5) and two shift elements (7, 8) for shifting to the forward or the reverse directions. The transmission ratio of the reversing gearset (1), in the reverse direction, is greater than one (i.e., it is a speed-drop ratio), such that in the forward direction, the transmission ratio of the reversing gearset (1) is equal to one.
