Japanese Patent JPS6057019
Kind Code:
A
Abstract:
PURPOSE:To reduce the cost and miniaturize a device by providing a start-adjusting/completely-fastening control valve on a controlling device for a stepless speed change gear. CONSTITUTION:On the control device of a stepless speed change gear, is provided a start-adjusting/completely-fastening control valve 108, which adjusts a start-adjusting pressure in accordance with the position of a rod 182, in and about the maximum speed change ratio position or in an overstroke area beyond the position of the rod 182 whose position is set by means of a speed change motor 110, and which feeds this adjusted pressure to a starting valve 116. Thereby, the control of a clutch feed pressure before starting, control of starting, control of complete clutch fastening, and speed change control can be carried out only by means of a speed change motor, without need for using a force motor. Accordingly, the cost can be reduced while the device can be miniaturized.
