摘要： PROBLEM TO BE SOLVED: To provide a toroidal continuously variable transmission in which a power roller can be prevented from coming off a trunnion at assembly in a structure in which the power roller is not supported on the trunnion via a displacement shaft.
SOLUTION: Grooves 160, 160 are each formed along the direction perpendicularly intersecting rotation center axis of the power roller 11 and perpendicularly intersecting pivot shafts 14, 14 on the inside surfaces facing each other of a pair of bent wall parts 20, 20 of the trunnion 15. Protruding parts 170, which protrude outside along the outside circumference so as to be inserted into the grooves 160, are provided on the outside circumferential part of the outer ring main body 28a of an outer ring 28.

In assembling, both the male and female parts 24 and 25 of the multiple sets of trunnions 4 and rods 8 having threading directions reversed to each other are simultaneously threaded and tightened with each other. By this configuration, forces based on tightening forces applied to the support plates 16 and 16 can be offset each other.

摘要： PROBLEM TO BE SOLVED: To prevent impartment of a sense of discomfort to an occupant; and to improve durability of a constituting member of a power transmission system, by relieving a sudden change in the gear ratio caused by switching both modes of a low speed and a high speed. SOLUTION: This continuously variable transmission is constituted by combining a toroidal type continuously variable transmission, a planetary gear type transmission, and both clutches 39b and 40b for the low speed and the high speed. When switching both modes of the low speed and the high speed, supply-discharge of pressure oil in hydraulic chambers 60 and 61 for both clutches of the low speed and the high speed, is controlled by switching both selector valves 66 and 70 for the low speed clutch and the high speed clutch on the basis of switching of a shifting selector valve 74. In switching, time for simultaneously connecting both these clutches 39b and 40b is set by setting delay time for switching both selector valves 66 and 70 for the low speed clutch and the high sped clutch. This constitution solves the problem by restraining the sudden change in the gear ratio caused by changing the direction of torque passing through the toroidal type continuously variable transmission in response to a mode change.

摘要： PROBLEM TO BE SOLVED: To prevent fretting abrasion between outside surface of an input side disk 4b and one side surface of a first connecting plate 43a and to prevent a transmission efficiency of a planetary gear type transmission 2b from being deteriorated if required. SOLUTION: The stepless transmission is configured to abuts one side surface of the first connecting plate 43a and outside surface of the input side disk 4b with respect to radial directions of the first connecting plate 43a and the input side disk 4b on inner diameter side and simultaneously to oppose them via clearance on outer diameter side as well. Thereby, an elastic deformation of the input side disk 4b is hard to transmit to the first connecting plate 43a. In addition, both of the side surfaces between one another abut only with a portion of low rigidity in axial direction of a carrier 7a, and form film for preventing abrasion on both of the side surfaces, and form a recess for storing lubricant.
