摘要： PROBLEM TO BE SOLVED: To accurately detect the state that a traction coefficient between a disk and a roller becomes approximately maximum.
SOLUTION: A mean slip factor calculating section 86 calculates a mean slip factor Sm at a contacting portion between the input disk or the output disk and the roller based on the rotational speeds ωi, ωo of the input disk and the output disk and the tilting angle θ of the roller, and outputs the calculation results to a traction state judging section 88. The traction state judging section 88 judges that a traction coefficient μ between the input disk or the output disk and the roller is approximately equal to a maximum value μmax when the mean slip factor Sm has exceeded a specified value X1, and outputs the judgement results to a pinch pressure control command calculating section 84. When it has been judged that the traction coefficient μ is approximately equal to the maximum value μmax, the pinch pressure control command calculating section 84 outputs a pinch pressure control command to a pressure control valve 54 to the input disk and the output disk in order to increase a pushing force Fa.

摘要： PROBLEM TO BE SOLVED: To provide a power transmission device to perform power transmission through a rolling contact of a troidal type CVT (a transmission with continuously variable gear ratio) in which the durability is enhanced.
SOLUTION: The power transmission device includes a roller 16 which makes rolling contact both with an input and an output discs for performing power transmission between the two discs. The surface 22 of the roller 16 confronting the two discs has a contacting part 26 which contacts actually with the input and output discs for performing power transmission. The width B of the surface 24 exceeds three times as large as the width 2b of the contacting part 26. This lessens the influence of the end face upon the internal shearing stress generated in the neighnourhodd of the contacting part to drop the stress. This drop of the stress lessens the amount of heat emission. The heat capacity of the roller 16 can be made greater by enlarging the width B of the confronting surface, and also the area of heat emission is widened. The drop of stress and the drop in temperature result in enhancement of the durability.
