TOROIDAL TYPE CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2005/100821
Kind Code:
A1
Abstract:
A toroidal type continuously variable transmission enabling the stabilization of the control of reduction gear ratio by preventing a trunnion (30 (31)) from rattling due to assembling clearances. An elastic material (63), which is a disk spring pressing the trunnion (30 (31)) to the axial one side of pivot shafts (33) and (33), is installed between a swing frame (21 (22)) and the trunnion (30 (31)). Namely, the elastic material (63) is installed between the inner side face of one end plate (48) fixedly joined to the swing frame (21 (22)) and a sliding member (65) fitted to the end face of one pivot shaft (33). By the elastic material (63), a force to move the trunnion (30 (31)) apart from the one end plate (48) is added to the trunnion (30 (31)) in the axial direction of the pivot shafts (33) and (33).
