What is the difference between CVT and ECVT?

[MacKingston]

ECVT is a hybrid transmission integrated with an electric motor, and its structure is completely different from CVT. CVT, when compared to traditional AT transmissions, can be understood as a continuously variable transmission, hence its Chinese interpretation as a continuously variable transmission. The specific introduction is as follows: 1. 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, control computer, etc. The composition is relatively complex, and the steel belt has limited torque capacity, so it is generally only used in small vehicles as a transmission system. 2. The structure of ECVT is much simpler. It does not have complex mechanisms such as clutches, torque converters, or gear shaft sets found in traditional transmission systems, but is composed of a set of planetary gears and two electric motors.
