What does ECVT continuously variable transmission mean?
1 Answers
ECVT continuously variable transmission refers to a hybrid transmission integrated with electric motors, which has a completely different structure from CVT, though theoretically it can achieve continuously variable transmission. The structure of CVT mainly consists of two sets of pulleys (drive pulley and driven pulley), a transmission belt (steel belt), oil pump, torque converter, actuating mechanism (valve body, oil circuit), sensors, and control computer. Its composition is relatively complex, and the steel belt has limited torque capacity, generally only suitable for use in small vehicles as a transmission system. The structure of ECVT is relatively simple, lacking complex mechanisms such as clutches, torque converters, or gear shaft sets found in traditional transmission systems. It is composed of a set of planetary gears and two electric motors.
