Abstract
A torque converter, a forward and reverse changeover apparatus including a planetary gear, a reverse brake and a forward clutch, and a lock-up clutch are integrally accommodated in the same torque converter case. Further, the planetary gear, the reverse brake, the forward clutch and the lock-up clutch are arranged on approximately the same plane expanded in the radial direction with respect to a transmission input shaft. Further, a forward clutch piston and a lock-up piston are arranged side by side on the transmission main shaft and a hydraulic chamber for operating the lock-up piston is provided independently from other hydraulic circuits. Thus constituted continuously variable automatic transmission provides a transmission having a short width and a good controllability.
