Abstract: In a wave gear device, an annular rigid externally toothed gear is disposed on the inner side of a cup-shaped flexible internally toothed gear. An internal-tooth-formation portion of the flexible internally toothed gear and a pushed portion pushed by a wave generator and flexed ellipsoidally are formed in different positions along the center axis line. The wave generator is disposed on the inner side of the flexible internally toothed gear, the pushed cylindrical portion is pushed from the inner side to the outside along the radial direction thereof by the wave generator, whereby the pushed cylindrical portion is flexed ellipsodially. As the outside diameter dimension of the wave gear device is determined by that of the flexible internally toothed gear, a wave gear device having a small outside diameter dimension can be obtained.

Abstract: A method of adjusting a pressure signal to an actuator piston to control movement of a synchronizer actuator fork of a transmission includes moving the synchronizer actuator fork from a start position into a target position by applying an initial fluid pressure value. The time required to move the synchronizer actuator fork is measured to define a measured actuation time, and compared to a target actuation time. A correction factor is applied to the initial fluid pressure value to define a revised fluid pressure value when the measured actuation time is not within a pre-defined time range of the target actuation time. When the measured actuation time is greater than the pre-defined time range of the target actuation time, the initial fluid pressure value is increased. When the measured actuation time is less than the pre-defined time range of the target actuation time, the initial fluid pressure value is decreased.
