無段変速機のプーリ作動油圧シリンダ装置。 A hydraulic cylinder that forms a hydraulic working chamber is formed in a non-rotating member such as a case member, and a piston that pushes a movable pulley is fitted into this hydraulic cylinder so that it can slide in the pushing direction. It is integrally attached to the non-rotating member in the direction of rotation,
A fluid bearing is formed on the sliding surface of the piston that makes sliding contact with the movable pulley, and in order to supply the hydraulic oil in the hydraulic working chamber to this fluid bearing as lubricant, the piston has a fluid bearing and a hydraulic working chamber. A lubrication passage communicating with the hydraulic fluid bearing is provided, and this lubrication passage is formed into a passage with a relatively wide cross-sectional area so that a rise in the hydraulic pressure of the hydraulic oil supplied to the hydraulic working chamber can be transmitted to the fluid bearing almost simultaneously, and a belt type continuously variable transmission characterized in that a spring means acting on the piston is interposed in the hydraulic operating chamber, and a preload is applied to a fluid bearing on a sliding surface of the piston with a movable pulley. Machine pulley actuated hydraulic cylinder device.
