K11CVT无段自动变速系统.PPT

* 注意: The general chain or rubber belt transmits power with pulling force. * It consists of a reverse brake fixing the ring gear and a forward clutch connecting input shaft and sun gear. Centrifugal fluid pressure canceling mechanism is used for the forward clutch. * [前進行駛時] The forward clutch is engaged and driving force is input into the sun gear. Therefore, the driving force from the engine is transmitted to the continuously variable transmission through the sun gear in the same direction. [倒車行駛時] Driving force from the engine is input into the ring gear with the forward clutch OFF. Driving force is transmitted to the continuously variable transmission in the reverse rotation by action with the planetary carrier locked by the reverse brake. * * * Belt clamp pressure is necessary for transmitting torque. 藉由調節第二轉盤壓力可控制皮帶夾力 Linear solenoid valve is used to control the belt clamp pressure by the optimal fluid pressure. * 藉由控制液壓流至及流離主轉盤以執行速率控制 This control is electronically performed, allowing greater flexibility to the speed ratio control. In addition, separating the acceleration and deceleration control achieved fine control and high reliability. * S速度感知器NIN; Detects primary pulley speed, Pick-up coil type 速度感知器NOUT; Detects reduction drive gear speed (= secondary pulley speed), Hall IC type 速度感知器NT; Detects forward clutch drum speed (= input shaft speed), Hall IC type 油壓感知器 Detects belt clamp pressure (= pressure for secondary pulley) * Construction of the parking lock mechanism is basically the same as general AT. * The CVT fluid warmer increases the warm-up speed of CVT fluid upon engine start and functions as an oil cooler during normal driving. * Maintenance schedule for CVT fluid is the same as general AT. * The K111 CVT does not have an oil filler tube and oil level gauge. When adding fluid, add fluid through the refill hole on the transaxle case. The fluid level can be adjusted by draining excess fluid through the overflow tube of the oil pan. 注意: Re
