Title:
CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2008/029697
Kind Code:
A1
Abstract:
Provided is a continuously variable transmission, which is constituted to comprise
an input shaft (20) disposed rotatably in a housing, a first speed change unit
(U1) and a second speed change unit (U2) so disposed in the housing as may confront
each other symmetrically with respect to a plane normal to the axial direction
(L) of the input shaft so that they may change the speed of the rotations of the input
shaft continuously with the traction force, an output rotation gear (90) supported
rotatably on the input shaft so that it may rotate in association with the rotations
changed in speeds by the first speed change unit (U1) and the second speed change
unit (U2), and an output shaft (110) disposed so rotatably in the housing as to
rotate in association with the output rotation gear. According to this constitution,
the torque of the input shaft can be continuously changed in speed while being
doubled by the two speed change units, and these two speed change units are so disposed
in the housing as may confront each other symmetrically with respect to the plane
normal to the axial direction of the input shaft, so that the thrust loads in the
axial directions of the input shaft can act in the opposite directions thereby
to offset each other.
