Continuously variable transmission with cooling structure for speed-change control actuator |
摘要 |
A continuously variable transmission for an automotive vehicle, including a power train whose speed ratio is variably changeable in accordance with an oil pressure signal from a control valve assembly. A mechanical feedback mechanism is provided including an actuator for speed-change control operable in accordance with an electric signal. The actuator has a solenoid section. A speed-change control valve is provided to control an oil pressure to be supplied to the power train. A speed ratio sensor is provided to be moved in mechanical relation to a part of the power train in accordance with a change in the speed ratio of the power train. A linking member is provided to link the actuator, the speed-change control valve and the speed ratio sensor. Additionally, an oil bath is provided to contain oil in which at least a part of the solenoid section of the actuator is immersed.
