What is the difference between ECVT and CVT?
1 Answers
ECVT and CVT mainly have the following differences: 1. Structural differences: The structure of CVT mainly consists of two sets of pulleys (drive pulley, driven pulley) and a transmission belt (steel belt), oil pump, torque converter, actuator (valve body, oil circuit), sensors, control computer, etc.; ECVT has a simple structure and does not have complex mechanisms such as clutches, torque converters, or gear shaft sets in traditional transmission systems. It is composed of a set of planetary gears and two motors. 2. Different working principles: In CVT technology, motors 1 and 2 need to work together, and the engine cannot directly drive the wheels in most cases; ECVT not only transmits power but also couples the energy of the engine and the motor to achieve power output, so it is actually a power combination system, specifically designed as a power distribution mechanism for hybrid models. 3. Different power solutions: ECVT is the electric transmission mechanism of Toyota's strong hybrid solution, composed of two motors and a set of planetary gears, which can achieve electric drive, continuously variable transmission, and energy recovery; CVT refers to ordinary mechanical continuously variable transmission.
