What is the difference between CVT and ECVT, and which one is more durable?
1 Answers
Due to inconsistent conditions for durability comparison, there is no direct comparability. The durability depends on the vehicle's usage. Below are the differences between these two transmissions: 1. Structural differences: First, the structure of the CVT transmission consists of a steel belt and a pair of pulleys, resembling two wheels connected by a steel belt that rotates. In contrast, the architecture of the ECVT is completely different from that of the CVT. The main components of the ECVT are planetary gears and an electric motor. By changing the combination of planetary gears, the motor's speed is altered, thereby adjusting the motor's power output to achieve different speeds and power levels. 2. Differences in power drive and transmission methods: Regarding power drive and transmission methods, the CVT transfers the engine's power to the vehicle through a driving pulley and a steel belt. On the other hand, the ECVT primarily relies on changes in the planetary gear structure to transmit power from either the electric motor or the engine, or a combination of both, to the vehicle. This involves differences in power drive, such as the distinction between electric motors, and differences in power transmission, including variations in planetary gears and the combination of electric motors and engines.
