Transmission ratio control system for a continuously variable transmission |
| 摘要 |
A control system has a transmission ratio control valve having a spool for controlling oil supplied to a cylinder of a drive pulley to change the transmission ratio. The transmission ratio control valve has chambers at both ends of the spool. The amount of oil supplied to the chambers is controlled by a control signal which is determined by a desired transmission ratio and the actual transmission ratio, so that the transmission ratio is controlled.
