What is the difference between Honda eCVT and CVT?
1 Answers
The differences between Honda eCVT and CVT are as follows: 1. Different structures: The structure of CVT mainly consists of two sets of pulleys (drive pulley, driven pulley), a transmission belt (steel belt), an oil pump, a torque converter, an actuator (valve body, oil circuit), sensors, and a control computer. 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; The structure of eCVT is simpler, without complex mechanisms such as clutches, torque converters, or gear shaft sets found in traditional transmission systems. It consists of a set of planetary gears and two motors. 2. Different principles: In CVT technology, Motor 2 is responsible for starting, low-speed driving, and hybrid driving; Motor 1 is mainly responsible for starting the engine and generating electricity. In most cases, the engine does not directly drive the wheels; eCVT not only transmits power but also couples the energy of the engine and the motor to achieve power output. Therefore, it is actually a power combination system, specifically designed as a power distribution mechanism for hybrid models. 3. Different power characteristics: eCVT is Toyota's strong hybrid solution's electric transmission mechanism, consisting of two motors and a set of planetary gears. It can achieve electric drive, continuously variable transmission, and energy recovery; CVT refers to the ordinary mechanical continuously variable transmission.
